A variety of technologies using portable devices in connection with media
content are detailed. Some enable users to participate interactively in
entertainment content, such as by submitting plot directions, audio
input, character names, etc., yielding more engaging, immersive, user
experiences. Other aspects involve a program directory database, compiled
automatically from information reported by network nodes that watch and
identify content traffic. By identifying content resident at a number of
different repositories (e.g., web sites, TV networks, P2P systems, etc.),
such a directory allows users to identify the diversity of sources from
which desired content can be obtained--some available on a scheduled
basis, others available on demand. A great number of other features and
arrangements are also detailed.
1. A portable device comprising: a wireless interface for communication
with a remote station; a memory; a processor responsive to instructions
stored in the memory; and a user interface; the memory containing
instructions that configure the device to: receive first user input,
through the user interface, concerning a name to be used in connection
with a character in a television program; receive second user input,
through the user interface, concerning clothing to be worn by a person
appearing in said television program; and transmit information relating
to the first and second user inputs, from the wireless device, using the
wireless interface; wherein the information transmitted from the device
functions to control, in part, selection of a name for said character,
and also functions to transform, in part, appearance of the person
appearing in the television program, the user inputs thereby contributing
to authoring of the television program.
2. A method comprising: receiving plural data, sent by wireless phones of plural television program viewers, relating to clothing to be worn by a person appearing in a television program; determining clothing to be worn by the person based, at least in part, on said received plural data; and clothing the person in accordance with said determining.
3. A method comprising: during presentation of a broadcast television program to a viewer, sensing a gesture of the viewer, the gesture including at least motion of the viewer's hand and arm, the sensing being performed by one or more sensors; sending data corresponding to the sensed gesture for use in connection with the broadcast television program; and controlling conduct of a character in the broadcast television program, in part, based on said sent data.
4. The method of claim 3 wherein at least one of said sensors is in a telephone device conveyed by the viewer.
5. The method of claim 3 wherein the character is synthetic, comprising computer generated imagery.
6. A method comprising: receiving audio information sent from a dozen or more telephone devices, corresponding to audio captured from viewers of a broadcast television program by microphones in said devices; using said received audio information to generate a composite audio track; and broadcasting said composite audio track as part of said television program.
RELATED APPLICATION DATA
 This application is a division of application Ser. No. 12/490,980, filed Jun. 24, 2009 (now published as US20100205628), which claims priority from provisional applications 61/167,828, filed Apr. 8, 2009; 61/160,660, filed Mar. 16, 2009; and 61/152,226, filed Feb. 12, 2009. These applications are incorporated herein by reference.
 The present technology concerns cell phones and other portable devices, and more particularly concerns use of such devices to enhance viewer engagement with television programs and the like.
 The present technology builds on, and extends, technology disclosed in prior patent applications by the present assignee. The reader is thus directed to the following applications (which are incorporated herein by reference) that serve to detail arrangements in which applicants intend the present technology to be applied, and that technically supplement the present disclosure:
 application Ser. No. 12/271,772, filed Nov. 14, 2008 (now published as US20100119208), entitled Content Interaction Methods and Systems Employing Portable Devices;
 Application Ser. No. 61/150,235, filed Feb. 5, 2009, entitled Second Screens and Widgets;
 Application Ser. No. 61/157,153, filed Mar. 3, 2009, entitled Narrowcasting from Public Displays, and Related Methods; and
 application Ser. No. 12/484,115, filed Jun. 12, 2009 (now published as US20100048242), entitled Methods and Systems for Content Processing.
 These earlier patent applications detail how a cell phone can watch or listen to the user's environment, and identify content (e.g., media objects or physical objects) from that environment. The cell phone can then be used to help complement the user's experience.
 The present disclosure details a great variety of further improvements and new innovations.
 For example, in accordance with one aspect of the below-detailed technology, it is not necessary for a cell phone to watch or listen to the user's environment. Guessing is often sufficient. The cell phone, or other device, may successfully infer--based on various factors (time of day, user location, television location, user viewing history, other profile data, EPG data, etc.)--the content, if any, to which the user is being exposed. (A die-hard Pittsburgh Steelers fan is probably in front of a TV screen at game time--whenever the Steelers are playing.)
 Once an initial inference has been made, additional information can optionally be sought to confirm or refute the initial hypothesis. For example, sound or imagery can be sampled--perhaps not enough to identify video programming in the absence of other information, but enough to reinforce (or discount) an initial inference. Alternatively, the cell phone can simply pose one or more confirmatory questions to the user, e.g., "Are you watching TV?" and/or "Are you watching the Steelers game on TV?" and/or "Are you watching program X or program Y (or neither)?"
 In other arrangements, the fact of viewing activity is inferred first. For example, if the locations of a television system and a cell phone can both be determined (e.g., by GPS), and the cell phone is found to be within ten feet of the television, then user viewing of the television may be inferred from proximity alone. If an affirmative inference is made by the cell phone, it can then estimate what programming is being viewed (e.g., by reference to current EPG data, user history and profile--accessed from a home network disk drive, or cached previously in the cell phone memory, etc.). If the television system makes the determination of proximity, it knows whether it is "on" and what programming it is rendering. It can transmit such information to the cell phone, so that either can then fetch auxiliary content for presentation to the user.
 Based on the thus-approximated circumstances, the cell phone can again provide a complementary experience to the user.
 One way to list available auxiliary content, without cluttering the intended video presentation, is to pause the main video programming. (The pausing may be user-initiated, or triggered by the system when auxiliary content is identified or becomes available.) A graphical control can appear--on either the cell phone or the main screen--from which the user can select desired auxiliary content. The graphical control can comprise, e.g., icons representing available auxiliary content--which selection changes in accordance with the contents of the paused screen. (E.g., if John Wayne is shown in the paused screen, then biographical information or other video clips about Wayne may be shown as available; a moment later, if Ronald Reagan is shown in the paused screen, then biographical information or other video clips about Reagan may be shown as available.)
 If desired, the cell phone may be programmed to cause the main video presentation to pause when a cell phone motion sensor(s) indicates a certain movement (or any movement). For example, if the cell phone senses that it is being moved from a rest position to a use position (e.g., to answer an incoming call), the television display may be automatically paused. If auxiliary content is being presented--on the cell phone or elsewhere--it too may be automatically paused.
 In some arrangements, a user's cell phone is registered as being associated with the user's television system. For example, in the user's TiVo digital video recorder, a data structure may store identifiers--such as phone numbers--of associated cell phones. Information relating to video programming (text alerts, auxiliary content, video content itself, etc.) can be sent from the television system to the associated cell phone(s).
 The registered cell phone may have a mode in which it is ready to present auxiliary content--call it a WatchingTV mode. (This status may be indicated by the cell phone to the associated television system, e.g., by the Apple Bonjour protocol or otherwise.) If the user's cell phone is in the WatchingTV mode, the user may be presumed to be viewing programming in accordance with past viewing history, recording history, preference data, etc. Auxiliary content can be provided to the cell phone accordingly.
 In other arrangements, a WatchingTV mode is not required. Information can be sent to the cell phone based on available programming and user data, which the user can choose to present on a screen, or not.
 If the user is determined to be remote from home (e.g., by reference to location information periodically provided to the home network from the user's cell phone), the system may determine how the user can access favorite programming (determined, e.g., by reference to previous viewing history or recording history) at the user's current location, and send such information to the user's cell phone.
 Similarly, reminders can be sent to alert users about programs of potential interest that are upcoming--localized to the user's current location.
 Although not presently implemented by TiVo, TiVo's design can be altered to support two or more users--each having their own viewing preference data, recording history data, and other profile data. Each user can have one or more associated cell phones registered with the TiVo device. When the television system is operated, but the user is not expressly declared, the system can infer the user's identity from various factors (e.g., comparing the content metadata, such as genre, title, synopsis with stored data for each user; considering time of day; determining the current locations of associated phones and identifying any that are proximate to the system; applying facial recognition techniques to image data captured by a camera to help sense particular users, etc.). System operations can then be tailored in accordance with the inferred user identity.
 It will be recognized that the cell phone can serve as a "second screen." The user can interact with the cell phone while others in the room watch the television screen--undistracted by overlays and other interruptions to the full-screen experience. They, in turn, may interact with their own cell phones--interacting with auxiliary content of their own choosing (and exchanging text messages and other content with others in the group). Yet the group has the shared experience of the common big screen and the common physical environment.
 (In some embodiments, groups can assemble on a virtual basis--from two or more locations. Each simultaneously views the same video content on a primary screen at their location, while also being able to interact with personal second screens--including online social interaction with other members of the group. The cell phones may simultaneously operate in conference call mode--allowing each person to speak to and hear others in the group.)
 When two or members of a group assemble for a second screen experience (physically or virtually), information may be shared between the members' cell phones. Each user may set an option on their cell phone indicating whether visual content information may be shared with other cell phones. If this option is set, then other members of the group can "tune into" the second screen experience of any other member (or all may share the same second screen experience).
 In other embodiments the cell phone need not be used to present content. Instead, it can simply provide information to other systems, e.g., identifying the user's location; or specifying--by reference to a calendar application--whether the user is free or busy; or indicating whether the user is stationary or in motion; or identifying which user is proximate to a particular display system, etc. The other systems can then adapt their operation in accordance with such information.
 Some embodiments allow the user to easily transfer displayed content from a cell phone screen onto a television screen for easier viewing. Conversely, the user may transfer displayed content from a television onto a cell phone for portability. The transfer can occur during playback of video entertainment or during game play, allowing play to resume from the point of interruption.
 Other aspects of the present technology enable users to participate in entertainment content, such as by submitting plot directions, audio input, character names, etc., yielding a more engaging, immersive, user experience.
 In accordance with still other aspects of the present technology, a program-centric content directory is compiled from information reported by network nodes that watch and identify content traffic passing into (and/or out of) network databases. Spanning a variety of content repositories (e.g., web sites, TV networks, P2P systems, etc.), such a directory allows cell phone users to identify the diversity of sources from which desired content can be obtained--some available on a scheduled basis, others available on demand. Depending on the application, the directory information may be transparent to the user--serving to identify sources for desired content, from which application software can pick for content downloading, based, e.g., on context and stored profile data.
 The foregoing are just a few of the novel aspects of the present technology. These and other features and advantages will be more readily apparent from the remainder of this specification, which proceeds with reference to the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
 FIG. 1 shows elements of an exemplary implementation incorporating aspects of the present technology.
 FIG. 2 is a block diagram of a digital video recorder system that can be used in certain implementations of the present technology, including certain stored data.
 FIG. 3 is a block diagram of a cell phone that can be used in certain implementations of the present technology.
 FIG. 4 is a representation of sample records from a database associating primary content with auxiliary content.
 FIGS. 5-8 detail aspects of an illustrative arrangement by which a Program Directory Database can be compiled automatically.
 Certain embodiments of the subject technology provide content on a user's personal screen (e.g., a cell phone) that complements content available on another screen (typically, a bigger screen).
 For expository convenience, content available on the bigger screen is often termed the primary content, and content presented on the personal screen (the "second screen") is regarded as auxiliary content. Examples of auxiliary content include audio and video, web pages and other textual data, application programs and software widgets. (In some circumstances, users may regard the auxiliary content as the more relevant and, in some circumstances, view it without viewing the primary content.)
 Referring to FIG. 1, certain embodiments 10 of the present technology can include a television system 12 and plural second screen devices 14, 16, 18.
 The television system 12 may comprise elements such as a set top box 20, a satellite receiver 22, a digital video recorder (DVR) 24, a television receiver/monitor 26, a Blu-ray device 28, and one or more other components 30 (e.g., a computer, a Slingbox device, an Apple TV device, an iPod, Boxee media center software, etc.).
 Primary content can be delivered to television system 12 by any communications channel 36. Examples include satellite, cable, wired- or wireless-internet, over the air broadcast, etc. A content distributor 32 (e.g., Comcast, DirectTV, a television network or station, etc.) typically aggregates content from various content sources 34 (such as film companies, content networks, sports teams, etc.) for distribution over communications channel 36. Other entities, such as the Apple iTunes store, Netflix, Google, YouTube, Hulu, peer-to-peer networks, etc., may also serve as content distributors.
 The auxiliary content can likewise be delivered by any communications channel 38. Often the internet 40 is used. The auxiliary content can also come from several sources, including the same entities that provide primary content, as well as from other sources (e.g., web sites such as Flickr and Wikipedia, advertisers, Apple App store vendors, social network friends and other individuals, etc.) In some instances the auxiliary content can comprise an associated software widget, e.g., as detailed in patent application 61/150,235.
 In one particular implementation, the auxiliary content is transmitted to the user's home over the internet 40, and wirelessly delivered to second screen devices 14, 16 from a router 42 over a home network 44. (Second screen content can also be provided to wired devices over the home network, such as a desktop computer 46, although this is not as common.)
 An exemplary DVR 24 is shown in FIG. 2, and includes a network connection 50 (e.g., to the home network 44). The DVR also has an input 52 through which video content is provided, as well as a phone connection 54. Input 52 can connect to a device such as a satellite receiver, a set top box, or an antenna, or it can eliminated if video content is provided to the DVR over the network connection 50. The phone input provides a connection by which the DVR can dial into a data center to download electronic program guide (EPG) data and other instructions periodically. Again, input 54 may be eliminated if such data is provided through the video or network inputs.
 The illustrated DVR also includes a processor 56, a user interface 58 (which may include both physical controls and on-screen menus/controls), a remote control 60, and a data store 62. The data store 62 can include both semiconductor and disc storage. In addition to operating system software, user interface software, and application programs, the illustrated data store 60 also includes EPG data, software widgets (see, e.g., patent application 61/150,235), other data and software program modules, and stored video data.
 Also included in data store 60 is a variety of user-specific data. This includes schedule data detailing programs to be recorded as well as programs earlier recorded, user profile data, and user cell phone data. The user profile data can include a variety of information, such as program viewing history, program recording history, season pass subscriptions and other standing recording instructions, viewer rankings and votes concerning certain programs, and other expressed viewing preferences. The profile data may also include demographic information such as zip code, user age and gender, data about affinity and social groups to which the user belongs, etc.
 In more sophisticated embodiments profile data is accessed from various data stores and can encompass the user's web browsing history and other sources of information. These can include all manner of data that the user touches and in which the user leaves traces, e.g., Google search history, cached web pages, cookies, email archives, travel reservations on Expedia and Orbitz, music collections on iTunes, cable television subscriptions, Netflix movies viewed and in-queue, cell phone billing statements, credit card statements, shopping data from Amazon and EBay, GPS tracking information, social network friends, data and activities, activities and postings on photo sites such as Flickr and Picasa and video sites such as YouTube; the times of day memorialized in these records, etc. (This collection may be termed a "digital life log.")
 Moreover, reference may be made to digital life log data of the user's family and friends, and for others having demographic similarities with the user (all this with appropriate anonymization and privacy safeguards).
 The DVR 24 may also have a module by which its location can be determined. One such module is a GPS receiver.
 FIG. 3 shows an exemplary cell phone 14, including elements such as a microphone, a camera 70, a processor 72, a display/touchscreen 74, a physical user interface, a location module, and memory. The memory stores operating system software, user interface software, other functional software modules, widget software, etc.
 The cell phone can employ a location module as described in connection with the DVR.
 In accordance with one aspect of the present technology, user profile data is used in conjunction with context information to make an estimate (or inference, or guess) identifying one or more particular television programs the user may be watching (or will watch in the future). The context information can include the user's location. It may also include whether the user is stationary at that location, or moving. Additionally, or alternatively, the context information can be television program schedule information, e.g., from an electronic program guide (EPG), and/or current date/time.
 To illustrate, profile information may suggest that the user is a committed fan of the Pittsburgh Steelers, and watches many other professional football games--routinely watching Monday Night Football. It may further indicate that the user watches most of the televised University of Oregon basketball games, occasionally watches some golf, and that the user's home television is most commonly tuned to ESPN.
 Location information may identify the user's location by latitude and longitude. Researching this location using one of the geolocation services identified in application Ser. No. 12/484,115 (e.g., Yahoo's GeoPlanet service) may indicate that the user is at Claude's Sports Bar on S.E. Hawthorne Avenue in Portland, Oreg. The location data may also be static over a period of time, indicating the user is not simply driving past the bar.
 With no other data, the system may infer the user is probably watching a sports channel on a television in the bar. The profile data indicates the user's interest in televised sports. A Google search for Claude's Sports Bar on S.E. Hawthorne in Portland finds a web page full of sports- and television-related references ("big screen" "satellite," "channels," "football," etc.). An inference engine takes these facts as inputs, identifies a set of stored rules relevant to such inputs, resolves any conflicts between the rules, and produces one or more inferences as output (e.g., that the user is probably watching television, and the watched television is probably displaying sports content).
 (Artificial intelligence techniques can be applied in these and in other contexts where the present technology is employed. One branch of artificial intelligence is natural language processing (NLP). NLP techniques can be used to make sense of information like the terms found on the web page for Claude's Sports Bar. U.S. Pat. No. 7,383,169 details how dictionaries and other large works of language can be processed by NLP techniques to compile lexical knowledge bases that serve as formidable sources of such "common sense" information about the world. Wikipedia is another reference source that can serve as the basis for such a knowledge base. This common sense knowledge can be applied in the processing detailed herein.)
 With more information, the system can make a more refined estimate--or a more confident estimate--about what the user is doing. For example, if the date and time indicate a Monday evening in November, an inference may be made that the user is watching Monday Night Football on ESPN. If it is a Tuesday evening when the University of Oregon is playing basketball, an inference may be made that the user is watching the basketball game--on whatever network it is airing.
 If it is a Monday evening in November AND the University of Oregon basketball team is playing a televised game, the algorithm applies other heuristics and/or profile data to address the conflict: is the user watching Monday Night Football, or the University of Oregon basketball game? From data such as the user's past viewing history, the inferencing engine may estimate that there is a 70% likelihood the user is watching the basketball game, and a 30% likelihood that user is watching the football game.
 Based on the inferences, the system identifies to the user's cell phone corresponding auxiliary content, e.g., of the sort detailed in the earlier-referenced patent applications. Two or more different auxiliary content options may be presented (e.g., in thumbnail or icon form; static or streaming), from which the user can select. These options may include, for example, NFL statistics for the playing football teams; a dedicated camera shot of the offensive quarterback, or an interactive game inviting the user to guess what play the quarterback will next call.
 Where the system yields a probabilistic outcome (e.g., 70% chance of football; 30% of basketball), the content or options presented to the user can be weighted accordingly.
 Likewise, the confidence of an inference can also influence what content or options the system offers to the user. For example, if the system is only 10% certain that the user is watching golf, it may not promote golf-related auxiliary content. Instead, it may offer default auxiliary content that more generally caters to the user's profile (e.g., highlights from recent Steelers football games and University of Oregon basketball games; commentary on their upcoming games; ESPN headlines, etc.).
 In some embodiments, the system checks its inference by asking the user one or more questions. For example, the system can send a text message to the user's cell phone inquiring, "Are you watching the University of Oregon basketball game?" Or an application program on the user's cell phone might present such a question. The auxiliary content (or content options) presented to the user can be tailored in accordance with the user's response.
 Instead of interrupting the user with such a query, the cell phone may simply capture audio or visual information from the user's environment (e.g., by the cell phone's microphone or camera)--seeking to confirm the estimate, e.g., by a technique such as a digital watermark decoding, or fingerprint extraction.
 Television audio typically bears a Nielsen digital watermark signal inserted by the content distributor (e.g., KOIN television), prior to its transmission. The watermark repetitively conveys two items of information: a source ID, and a time stamp. The source ID has two parts. The first generally identifies the network from which the content is distributed, e.g., CBS, ESPN, etc.; the second identifies the local outlet, e.g., KOIN television, Comcast cable-West Portland, etc. The time stamp is an incrementing clock that gives the date and time of the transmission. The encoders that insert the watermarks are part of an existing network that helps The Nielsen Company track television consumption. Nielsen maintains a database that details the program lineup for each channel in each geographic market and national network, by date and time. This database is fed by program guide information compiled by vendors such as Tribune Media Company and/or TV Guide.
 A customary watermark usage model is to identify an unknown television program from a watermark. In that case the watermark ID/time stamp are input as a query to the database, and the database returns output data identifying the program that was airing on that television source at that time.
 The present application is somewhat different, because a guess as to the likely program(s) has already been made. In this case, information identifying the estimated program(s) is used to query the database, and retrieve the source ID (and optionally time-stamp data indicating the scheduled time for the program). Audio captured from the user's environment is then checked to see if it is consistent with the retrieved source ID. (Technically, it is easier to analyze audio to determine whether one or more expected watermarks is present, than it is to analyze audio to identify whether an unknown watermark is present.)
 The system assumes that the content available in the user's environment is being presented during the program slot of its original transmission. The database is thus queried to identify the source or sources that are currently transmitting the estimated program. For example, Monday night football may be distributed by ESPN and by a local broadcast station. Source IDs for these sources are then obtained from the database, and the ambient audio in the user's environment is analyzed to determine whether a watermark corresponding to one of these source IDs is present. If so, the estimate has been confirmed. (A similar approach can be employed with recorded content, although a larger universe of candidate programming must be considered.)
 As noted, another approach to content identification (or confirmation) is fingerprinting. Fingerprinting works by matching features from unknown media content with features from known media content, to make an identification. Again, the present context is simpler than that usually presented, since the system has already made an estimate about the identity of the content. So the captured audio (or imagery) is simply analyzed to check for consistency with the estimated program, in order to confirm the estimate. (For example, fingerprints for the estimated program may be checked for correspondence to the sampled audio; this is a simpler task than using fingerprint technology to identify sampled content from a virtually unlimited set of possibilities.)
 In still other arrangements, the sampled audio or imagery simply tends to confirm that the user is watching television, rather than engaged in some other activity. For example, television audio often has a spectral distribution that can be distinguished from, e.g., the spectral distribution of two people engaged in conversation. Television audio is frequently band-limited and compressed (limited) to increase its average power, and to concentrate its energy where the human auditory system is most acute. Similarly, TV video has distinctive visual features. CRT television monitors use color phosphors that produce characteristic peaks in the visual spectrum. Television screens are refreshed at a fixed rate, by which their imagery can be distinguished from natural scenery. These and other hallmarks can be used to help confirm that a user is watching television instead of, e.g., engaged in discussion or watching a live football game.
 In one implementation, the processing described above is performed by processor 72 and associated applications software in the user's cell phone. In other implementations this processing takes place in the user's DVR, or at a cable company server, or in the cloud, or elsewhere (or distributed among such processors).
 Sometimes the user may be traveling in a city remote from home. The user's position is known by GPS or otherwise. However, the television programming available in that remote city may be different than that normally tracked by the user's cell phone or the home DVR. In such cases the system can use online resources, such as the TV Guide web site, or data from Tribune Media Company (or the Program Directory Database detailed below), to determine the availability and scheduling of content in the remote city. With knowledge of the programming line-up available in the remote city, together with the user's location and profile information, the system may still estimate a particular program that the user is currently watching (or may watch in the future).
 Information about the user's estimated viewing activity can be sent back to the user's home (if it was determined by a remote device), where it can be stored or otherwise used as particular applications may require. If the user confirms a viewing activity, this information can be similarly logged, e.g., in a data store coupled to the user's home network.
 The arrangement just-described guesses at what the content the user is presently viewing, and acts accordingly. A similar procedure can be used to guess what content the user will be viewing in the future--or may be interested in viewing. Auxiliary content, or reminders, can then be sent to the user--immediately, or later.
 A particular implementation receives data indicating a location of the user (e.g., a location of the user's cell phone) and, in conjunction with profile data relating to the user, identifies one or more upcoming television programs that the user may want to view. Alerts are then sent to the user (e.g., to the user's cell phone) about the upcoming television program(s). The alert may invite the user to press a button, or otherwise signal, if the user is (or will be) watching the program. Again, if the user is remote from home, program line-up data from the media market where the user is currently located can be used to customize the alert.
 The profile data may be as simple as information indicating that the user's home DVR is set to record a particular program at a particular time. For example, the user may have earlier operated the user interface of a home TiVo device to program a "season pass," instructing the device to record all broadcasts of Minnesota Timberwolves basketball games. At the time of each game, or a brief interval in advance (e.g., 5, 15 or 60 minutes), the system may send the user a reminder that a game is about to air. (In the DVR shown in FIG. 2, the user's cell phone number is known to the DVR--allowing it to send such a reminder by a text message, a voice alert, etc.)
 If the user confirms viewing a particular program (or if viewing is confirmed otherwise, e.g., by audio sampling), this fact can be relayed to the network, to the content creator, or to other parties--allowing them to offer complementary auxiliary content. To illustrate, a user may be invited to participate in an online poll to determine Player of the Game for a football game, or who should be voted off the island in a reality show. The outcome of the primary content may thus depend, in some measure, on involvement of the audience with the auxiliary content. (This feature is discussed in further detail, below.) In another example, a user is presented with occasional trivia, e.g., that President Obama is a longtime Pittsburg Steelers fan. If user profile data is shared with the networks etc., they can better engage the viewer with meaningful auxiliary content.
 In some embodiments the user can respond to the alert by requesting that the scheduled program be transmitted to the user's cell phone for viewing.
 Just as the fact of a user viewing a television program may be inferred, so may be the fact of a user discontinuing viewing. This can be done, for example, by sensing audio or image data using the cell phone. It may additionally or alternatively involve sensing movement of the cell phone (such as by accelerometers, or movement of visible features in a field of view of a cell phone camera).
 If the viewer has apparently stopped viewing the television, corresponding action(s) may be taken. One is to pause the programming, so that the viewer can resume watching at a later time. Another is to send the viewer information about a missed portion of the content. This can comprise key frames, video highlights, a textual synopsis, etc. One or more of these can link to a recorded version of the missed content.
 As noted, one or more cell phones may be associated with a particular television system, e.g., by registration data in a DVR data store, or elsewhere on a home network. Information can then be shared between the system and one or more of the associated cell phone(s).
 In a particular arrangement, a husband and wife both have cell phones registered with a family TiVo system. Each may have their own TiVo profile including, e.g., preferences, viewing history, video recordings, season passes, etc.
 In some cases it is clear whether the husband or wife is associated with a given program. For example, a program may have been recorded at the instruction of one or the other, and appear on their respective list of recordings. When the television plays the recorded program, it may direct auxiliary content (or a message about the availability of auxiliary content) to the person who scheduled the program for recording.
 In other cases there is ambiguity about which person (or both) is associated with a program. Consider a Saturday afternoon when someone turns on the television system and tunes to a golf broadcast. Who is watching? A variety of heuristics may be applied.
 One is to analyze past recording history. If the wife's list of recordings includes golf broadcasts, but the husband's does not, then the system can infer the wife is watching. Data may thus be directed to the wife's cell phone. Other profile data can be used to similar effect.
 Another approach is to sense location of one or both phones. Data can be sent to whichever phone (or both) is near the television system.
 The phone may be running the Bonjour protocol--advising other devices on the home network of who it is (e.g., to which spouse it belongs) and what it is doing. The television may receive this broadcast and thereby identify a phone watching television.
 A variety of other arrangements can also be adopted. For example, the television system may include a camera and facial recognition algorithm to identify the viewer(s). It may monitor periodic transmissions from the cell phone by which it identifies itself to the local cell site. Or the television system may simply inquire of one spouse whether they are watching golf. If the person responds `yes,` auxiliary content information can be sent to that spouse; if `no,` the auxiliary content information can be sent to the other spouse.
 In the example just-given, the television system is pro-active: seeking to identify a viewer so that auxiliary content may be provided. In other arrangements it works the other way. A user may operate a cell phone (e.g., by launching a WatchingTV application) to indicate interest in auxiliary content or other interactivity. A logical association is then determined between the cell phone and a television system. This association may be ad hoc, or determined by information previously-stored in a data registry or the like.
 An example of the ad hoc case is a phone that senses it is near a television system, such as by location determination, by Bonjour broadcast from a local wireless network, by watermark or other distinctive feature of ambient audio/video, etc. (Identity of the television system may be established by decoding a digital watermark encoded in content rendered by that television system, where the watermark conveys an identifier of the particular television system.) Once a logical association is established, auxiliary content corresponding to primary content displayed on the television is provided for the user's enjoyment. (As in other cases, the auxiliary content may be dependent on the user profile, user location, etc.)
 In the other case, the logical association is determined by information previously-stored in a data registry or the like. An example is a phone registered with the user's home TiVo system. In some instances the user may not even be near the associated television system. Nonetheless, the user's cell phone can consult with the associated television system and present related information to the user. The presented information may simply comprise the status of the television system, or the name of a program being viewed or recorded on that system. Or it may comprise auxiliary video or web content corresponding to content being processed (or earlier stored) on the associated system. (Here, as in the other embodiments, the cell phone may present a menu from which the user can select among plural options. If several different items of auxiliary content are available, the menu may comprise thumbnail views of the content--including motion video--from which the user can select.)
 It should be recognized that the second screen auxiliary content may be some or all of the primary content, depending on the application. For example, in a circumstance earlier-discussed--in which a user is alerted to a program about to be recorded on a home DVR--the auxiliary content may be the primary content re-formatted and streamed for presentation on the user's cell phone display. The user interface on the cell phone can alert the user to the availability of such content, which can be played by a corresponding gesture on the phone's touch-screen interface.
 In this and other embodiments, the user may respond to an offer of auxiliary content by instructing that the auxiliary content also be offered, or directed, to one or more other cell phones or second screens. Thus, when a user's cell phone is alerted that a Timberwolves game is beginning, the user can forward the auxiliary content to the user's laptop, and also offer the auxiliary content to the cell phone of a classmate who is also a Timberwolves fan. Such relaying can be done by wireless from the user's cell phone (e.g., by Bluetooth for nearby second screen devices, or by WiFi and then internet to more remote devices). The Bonjour protocol can alternatively be employed--transmitting data that can be received by all devices on the home (or other) network.
 In some embodiments the user's cell phone may instruct that the auxiliary content be distributed to the designees from an upstream node in the distribution process (e.g., from one of the servers 34 in FIG. 1, or from the user's home DVR 12, etc.).
 The content may be shared with individuals with whom the user has an association (e.g., "friend" status on a social network), or to individuals who are physically nearby, or to individuals in the user's phone book, or on a common network, etc.
 The shared content may appear on the other person's cell phone in a sub-portion of the display screen, e.g., in a window. By selecting the window, the other person may cause the display to occupy the full screen. Desirably, the content is presented simultaneously on all screens on which it is displayed.
 In some implementations, the DVR can be programmed to send program alerts to multiple individuals, and make auxiliary content available to each if requested.
 It is not necessary to know the user's absolute location in order to infer that the user is watching television. In other arrangements the mere fact that a user is in proximity to a television can be inferred, and action can be based thereon.
 Various techniques for inferring proximity were discussed above, e.g., detecting characteristic features of audio and imagery produced by televisions, as contrasted with other audio and imagery. Low level stray emissions from televisions or other video equipment can also be detected (e.g., the colorburst oscillator of an NTSC television; the refresh rate for a television screen, or a video scanning frequency, etc.). A Bonjour protocol transmission from the television can also be used.
 Conversely, the television may detect the nearby presence of a cell phone, e.g., by the near field RF signal regularly transmitted by the phone to the cellular network, by the near field WiFi signal sent to a nearby router, by a Bluetooth emission, by a Bonjour protocol transmission, etc. The television system can identify the cell phone by such transmission, and--once proximity is established--an estimate can be made of the television content that the user is most likely viewing.
 Once proximity is established between a user and a video screen, auxiliary content can be provided to the user in accordance with user profile data.
 Eventually the day may come when all devices know their own location, such as by one of various emerging geolocation arrangements (e.g., as detailed below). They may share this information with local devices (e.g., by wireless and/or Bonjour), and/or post the location data to a networked data store--where it can be accessed by other devices. In this environment the user's cell phone can learn the location and identity of nearby electronic devices (which may be presented in map form). If a television monitor is found to be near the cell phone, the system may infer that the user is watching the television. ("Nearby" depends on the particular requirements of a given application. In some cases ten feet may be nearby. Sometimes twenty. In the case of a Jumbotron video monitor, ten or a hundred yards may be considered nearby.)
 Next generation video systems may also publish data (e.g., wirelessly, by Bonjour, or to a networked data store) identifying the content they are displaying. In such case an estimate of the content no longer needs to be made. The video equipment unambiguously makes this information available. Systems using the present technology can access such information and, based thereon (and, optionally, on profile data), provide corresponding auxiliary content to the cell phone of a nearby user.
 In these examples, as earlier, the system may seek confirmation, e.g., that the user is actually watching the video content being displayed on the nearby screen. Such confirmation may be sought recurringly, rather than just once.
 In all of these examples, the auxiliary content need not be presented on the user's cell phone. It may be presented on the big screen with the primary content (e.g., in a window). Or it may be delivered otherwise.
 In addition to (or as an alternative to) presenting information or content to the user, a cell phone can simply provide information to other systems. For example, it can identify the user's location; or specify--by reference to a calendar application--whether the user is free or busy; or indicate whether the user is stationary or in motion; or identify that a user is proximate to a particular display system, etc. Next generation cell phones may report biological indicators, e.g., suggesting whether the user is asleep or eating, etc. The other systems can then adapt their operation in accordance with such information.
 For example, if a television system in an airport lounge senses the stationary nearby presence of Jane Doe (or more accurately her cell phone), the television system may retrieve profile information for Jane Doe (e.g., from the phone or an online resource), and identify what video programming may be of most interest, e.g., a current LPGA golf tournament. The television can automatically present such programming to Jane while she waits. When Jane leaves and John Smith sits down, the television may similarly tune to CNBC.
 Instead of, or in addition to, selecting primary programming, such a system can identify auxiliary content of particular interest to the nearby user. For example, John Doe's cell phone may make available, over a WiFi network or Bluetooth, the names of stocks on his default Yahoo Finance portfolio (but not the share amounts). The television system can automatically overlay a small window on the CNBC screen, scrolling current prices for those stocks.
 Thus, while cell phones according to the present technology can respond to the user's environment, they also allow the user's environment to respond to the user.
More on Auxiliary Content
 The item(s) of auxiliary content that is made available with a particular item of primary content may be selected by the provider of primary content (e.g., a video network, such as ESPN), or another network or commercial entity. However, an alternative is for auxiliary content to be crowd-source-identified, e.g., in social network fashion.
 The social network can be defined in advance (e.g., Facebook friends of John Doe, or high school students in Portland, Oreg.), or it can be ad hoc (e.g., whoever is currently watching tonight's Timberwolves game).
 Individual users may find their own auxiliary content. For example, high school students watching a James Bond movie may browse to the Austin Martin home page, or to the home page for the United Kingdom's MI6 Secret Intelligence Service. Retirees watching the same movie may tend to browse to the Wikipedia page for "Shaken, Not Stirred." Or to the Tanqueray Gin home page.
 Similarly, when watching NBA Minnesota Timberwolves basketball, high school students at the alma mater of player Kevin Love may navigate to the page at NBA.com with Kevin's statistics, or to a YouTube video of him breaking a basketball backboard during a celebrated high school game.
 , and can serve as a resource from which others can identify relevant content. Each item of auxiliary content may be associated with (1) profile information about users who viewed it, and (2) information identifying content with which it has been associated.
 One implementation employs a relational database that can group data using common attributes. A schematic representation of data in such a database is shown in FIG. 4.
 Naturally, this is just a sampling. The database desirably includes, or has access to, other data. This other data can include metadata associated with each item of content--classifying by genre, actors, keyword descriptors, ISAN (International Standard Audiovisual Number) and/or DOI (Digital Object Identifier), date, etc. Additional profile data for each user can also be provided, e.g., telephone number area code and exchange; IP address (or domain), and profile information noted earlier.
 This data can be mined in other ways. A person who independently browses to the MI6 official site might be prompted to consider viewing the Goldfinger movie, etc. A web browser may briefly overlay a sidebar on presented content, advising "Users that were interested in this page were also interested in the following: <identification of other content>"
 Such a database can be hosted on a discrete computer, or distributed (and/or replicated) among many different platforms. Peer-to-peer arrangements can be employed, with different parts of the database residing on different users' machines.
 Such a database may be managed in wiki form, with users expressly contributing and annotating the listings. Another alternative is for a vendor such as Google to compile the data. A new service (e.g., "MediaGuide") could then be provided, which would provide a ranked list of auxiliary content (e.g., web pages) that is most commonly consumed with a given item of primary content (e.g., a television show).
 Already, assenting users of the Google Toolbar product provide data to Google identifying visited web sites. The Google Toolbar can be enhanced to also provide
 Google with data identifying media content that is present in the user's environment during web browsing (a background media data collection mode).
 The media content can be identified by the various techniques detailed in this and the incorporated-by-reference documents, including digital watermarks, fingerprints, etc. The Google Toolbar may fully identify the content (e.g., by decoding a watermark from captured audio), or it can simply perform some processing of captured audio (or video), and forward the processed data to Google's servers for completion of the identification task, such as by fingerprint matching. (The processing desirably removes personally identifiable information, such as by making the audio unintelligible. One type of such processing is Wiener filtering, or subtracting the short-term average of the audio amplitude from its instantaneous value. Another is by extracting the timing and frequencies of certain landmarks in the audio, e.g., as detailed in Shazam's U.S. Pat. No. 7,359,889.)
 The ambient media needn't be identified with a high degree of certainty. Guesses based on incomplete data or circumstances (as described elsewhere in this specification) can often suffice--especially when large numbers of such data are collected. Associations between primary content and companion auxiliary content based on correctly-identified primary content tend to cluster; clear patterns emerge. For example, many viewers of Oprah's television program may visit web pages for the Oprah Book Club and for personalities appearing on Oprah's show; many viewers of CNBC may visit the Wall Street Journal web site and the Yahoo Finance web site. Associations based on mis-identified content, in contrast, are un-clustered; they don't occur with the frequency that would place them among the top ranked search results. So even if the media identification were correct only 20% or 2% of the time, useful associations would eventually emerge.
 In other embodiments, no guessing or discernment is required; the primary content is expressly identified by data from the television system, or from a device elsewhere in the distribution/rendering chain. For example, a TiVo box knows what content it is supplying to a television monitor, and it can make this identification data available to the Google Toolbar. In one particular embodiment, software in the TiVo system employs the Bonjour protocol to inform other devices within the home network of the identity of the video being currently rendered. The Google Toolbar software can receive this broadcast, and forward same to Google (as it forwards data identifying visited web pages).
 In query mode, the contemplated MediaGuide service takes identifiers of primary content as input, and provides a ranked listing of corresponding auxiliary content identified from the database as output. The input identifiers may be keywords typed by a user, e.g., Oprah or CNBC. Alternatively, the user's device (e.g., a module associated with the Google Toolbar) may simply sample the ambient audio (in response to user command, or automatically) and provide associated identifiers to the service. These identifiers may be text keywords (e.g., program title), or other identifiers that are associated with a particular program (e.g., watermark payload, audio or video fingerprint, etc.) In some embodiments, the captured audio data, or processed audio data, may be submitted as input, and the Google servers can identify the primary content based on this audio data--and respond with ranked identification of corresponding auxiliary content.
 In still other embodiments, the primary content is expressly identified by data from the television system, or from a device elsewhere in the distribution/rendering chain, as detailed above.
 Results from such a MediaGuide query may be presented in the same familiar format as Google's web search results. Hyperlinked results from the database fill most of the screen. To the edge can be placed sponsored links. For example, Nike may pay to present a link to its Air Jordan web page on the top right of a page of results to a media query based on a Trailblazers basketball broadcast.
 After an initial corpus of primary content-auxiliary content association data is collected, use of the system in query mode allows further media association data to be collected. The Google Toolbar can note which auxiliary content search results are selected when different primary (ambient) media is present. This information is sent to Google and can inform future searches based on that primary media content.
 The search results may be customized for the user's demographics (e.g., age, gender, zip), if demographic data is known while in media data collection mode. For example, a MediaGuide query based on a Trailblazer basketball game by a 19 year old male in Portland can report the most popular auxiliary content consumed by other users of similar profile.
 It will be recognized that the just-detailed arrangement is a departure from the usual careful scripting of content consumption. Historically, commercial entities--such as advertisers and content networks--paired primary content with auxiliary content (consider broadcast television and associated commercials). The present approach, in contrast, taps a wealth of information by examining actual user behavior--establishing appropriate content pairings organically rather than by fiat.
 While described in the context of Google offerings, any number of particular implementations is of course possible. One employs Personal People Meters (PPMs)--pager-sized devices that sense ambient media for audience survey purposes (see, e.g., Nielsen patent publication 20090070797, and Arbitron U.S. Pat. Nos. 6,871,180 and 7,222,071). Audience survey companies recruit and compensate individuals to wear such meters. These same individuals may be recruited to install software with their web browsers to report what web sites are visited, when. An individual's web site data and PPM data can then be temporally correlated to establish associations between web content and broadcast content.
 Similarly, instead of using the Google Toolbar software, such data collection can be effected by a network-connected media monitoring device, such as the one detailed in Nielsen's patent publication 20080320508.
 It will be recognized that the technology detailed herein offers enhanced audience measurement for television and other content. The operator of such a system receives real-time information about the consumption of media worldwide. Audience analysis techniques, such as used by Nielsen and Arbitron, can be employed.
 Moreover, the detailed system provides another dimension of audience information, namely information about co-consumed content. This can be of particular use to advertisers.
 Consider a company that wants to promote its product to a particular demographic that is not tracked by traditional television audience measurement surveys, e.g., frequent leisure travelers. In the past, other metrics have been used as gross proxies for the desired demographic, e.g., persons 49-64 with incomes over $100,000. But this is unsatisfactory--often identifying programs that are not relevant, or failing to identify programs that are relevant.
 Paired with web visit data, however, television audience measurement takes on new meaning. Instead of identifying a demographic proxy for the targeted group, the advertiser queries the just-detailed database with web sites that serve the targeted group, e.g., Expedia, Travelocity, Priceline, Hotwire. In this mode of operation the database responds with the names of television programs that most commonly are being rendered while such sites are being visited. Television programs that provide the desired audience demographic are readily and confidently identified.
 If a company wants to advertise on television programs popular with off-roaders, it queries the database for programs associated with the web sites Fourwheeler, Offroaders and Pirate4×4. If a company wants to advertise on television shows watched by families dealing with Alzheimers, it queries the database for programs most-commonly watched while surfing the Alzheimers' Association web site. For programs watched by online gamers, it searches the database for programs airing while users are at popular gaming sites (e.g., World of Warcraft).
 Such an approach provides a significant advance in the accuracy of television audience measurement. No longer are viewers classified solely by generic demographics such as age, geography, income, education, etc. Now their subjective interests are revealed--factors that distinguish statistically identical neighbors. And such interests are not collected using questionnaires of uncertain reliability, but by reference to actual web browsing habits.
 The ambient media information can be used in other ways as well. One is as cookie information. Cookies have long been used to allow websites to tailor their presentations to returning users, e.g., customizing the presented information based on users' past activities or interests. Likewise, information about a television program currently being rendered to a user can be relayed to a web site to which the user surfs, and the web server can adapt its presentation accordingly. If sports programming (e.g., content from ESPN) is sensed in the viewer's environment, and the user navigates to the New York Times website, the Times web server may present sports news more prominently than otherwise. Similarly, if the program Washington Week in Review is playing in the user's environment, the Times web site may give greater prominence to national political news in the first web page served to the user.
 This need not be implemented using traditional cookies. Other data exchange arrangements can be used. One data exchange arrangement is as header data in the HTTP packet sent to the New York Times web site, asking for a page to be loaded. The header data already carries a variety of information, such as data identifying the web site from which the user just navigated (the referring page). It can also carry data identifying the television program currently playing in the user's environment, so that the responding web site can adapt its content accordingly.
 In this embodiment, as in others, the data identifying the television program can be of any form. Examples include ISAN identifiers, time/channel data, audio data from which a remote detector can discern identifying watermark or fingerprint data, decoded watermark data, fingerprint data, EPG coordinates from a TiVo system, text title data (e.g., from an EPG), etc.
Organically Compiled Program Directory
 The concept of a program guide is an old one, dating back to the earliest days of television, and printed TV Guide magazines. A gridded structure is used, with columns indicating time (usually in 30 minute increments), and rows indicating channels. With the development of cable networks featuring large numbers of channels, this gridded format migrated to scrolling on-screen guides--originally delivered on cable channels dedicated for this purpose.
 A great number of subsequent technical developments have occurred in the field, but the gridded time/channel format remains entrenched.
 Schedule data for TV Guide, and the later electronic counterparts, has traditionally been compiled by a labor intensive process. Clerical workers at TV Guide, and later Tribune Media Services, called television networks and individual stations on a regular basis to obtain program lineup information for the week ahead. When last minute program changes occurred--as unavoidably happens--the guides presented incorrect information.
 In accordance with aspects of the present technology, the inventors believe that it is time to disintermediate programs from channels. The consumer has a display screen, on which content desirably appears (whether from TV broadcast, cable, web streams, iTunes, Netflix, peer-to-peer networks, etc.). Channels as an organizing principle have outlived their usefulness. (Identifying content by reference to channels is akin to identifying postal mail by reference to the name of the mailman that brings it to the door, or identifying a web page by reference to the data's routing through nodes of the internet.) How content gets to the consumer's screen is of secondary interest--if that.
 An embodiment incorporating this aspect of the technology may refer to a program-centric directory that details multiple alternate sources from which content may be available. Instead of indicating a desired channel, a consumer indicates a desired program. An automated system, referring to the directory, chooses from among the available sources and presents the desired content on the screen. Only rarely does the consumer need to be involved.
 In one particular embodiment, the system employs stored heuristics and rules, which cooperate with user preference and profile data, to choose from among different sources for content. A user may express a preference, or a requirement, for downloaded content over streaming, free content over paid, no commercials, resolution of at least 1024×768, no delivery for sources that may be unauthorized, etc. Some such preferences may apply across all content types; others may be tailored to particular types of content (e.g., theatrical movies and sports: prefer resolution of at least 1024×768; current events and comedy: prefer resolution of at least 720×480; paid content: require no commercials). The preferences/requirements can be applied in a particular order (e.g., always exercise the user's first preference, where possible, without regard to whether meeting that preference means other preferences will not be met). Alternatively, the preferences can be accorded different relative weightings, with a final choice made only after each alternative has been scored in the aggregate--considering all the relevant preferences and weightings.
 Sometimes the rules/heuristics will refer the decision to the user. For example, a rule may specify not to automatically authorize any content payment exceeding $0.99 ($2.99 in the case of a movie within two weeks of its theatrical release). The user can then specify, through a phone or other UI, whether to authorize the payment.
 In other cases the user may specify and ordered list of preferred providers. Obtain from Hulu, if available; else obtain from YouTube, if available; else obtain from iTunes, if available; else present options to user for manual selection.
 FIG. 5 illustrates a database record corresponding to an episode of the Daily Show program. The illustrated data structure gives information about the program, and lists various sources from which the program is available. Some are web sources. Some are TV sources. One is from a P2P network (Limewire).
 Associated with each of the listed content outlets is further information about the content (metadata), such as an identifier used by that outlet (e.g., 77973 for Hulu), the ISAN number for the content (where available), and information about availability of the content from that outlet.
 For some outlets, the availability information indicates that the content is available "on demand." The information may further specify when the content was first available from that outlet, and may specify when availability is expected to end.
 For example, the sample Daily Show episode was available on Comedy Central (its originating network) at the date and time the episode originally aired (i.e., 8:00 μm on June 15), and is available until midnight on the Sunday before the fifth week anniversary of the original airing. The copy provided to Hulu, however, was embargoed for an hour--not being available from that source until 9:00 p.m., and is available from that source for only 30 days.
 In the case of television broadcasts, the data structure includes a pointer to a list of arbitrary length, detailing the original airing and all scheduled repeats of the program. Thus, the Comedy Central TV entry shows the original 8:00 p.m. airing, followed by a repeat at 10:30, 7:30 the next morning, etc. (In the illustrated data record, all times are Pacific.)
 Included in the same database as contains the FIG. 5 information, or in another, is a data structure that maps television networks to channels. For example, Comedy Central is channel 107 on the Dish Network, channel 55 on Comcast, etc. By reference to such information, a user's system can locate the desired programming on different distribution systems.
 FIG. 6 shows how the source data is collected. The content creator provides each item of content with an inherent identifier that can be digitally extracted from the content wherever it goes. Digital watermark technology is preferred, although fingerprinting can also be used. The identifier is stored in a database, together with metadata about the content. The content is then distributed to one or more recipients, such as television networks, web sites, etc.
 Recipients of the content are equipped with watermark (and/or fingerprint) detectors (shown by triangles in FIG. 6) that read the content's inherent identifier, and issue reports back to a database. (See, e.g., Digimarc's patent publication 20070208711 for additional information about such watermark/fingerprint detectors.) Desirably, each recipient includes recipient-specific information with the report, such as particulars of the intended use. These particulars may include scheduling data (e.g., when the content is to be broadcast, when it is to be downloadable from the web, when availability will be discontinued, etc.). Other information may also be included, such as the format(s) in which the content is/will be available, the identifier assigned to the content by the recipient's system etc. The database thus has a record of where the content is stored, together with all of the other recipient-contributed information.
 In addition to locating detectors at content ingest points for authorized distributors, the detectors (triangles in FIG. 6) may also be placed elsewhere to identify the content at other locations, such as it leaks to unintended destinations. For example, an individual may download the content from a web site, and re-post it on a P2P network site. A detector at an internet node may sense the P2P traffic, and submit information to the database identifying the P2P network as an alternative source for the content.
 FIG. 7 shows the content creator's (e.g., a movie studio's) part of the process in greater detail. The content is originally created by film or digital capture. Dailies are reviewed by the production team, and editing takes places. If the content is originated in film, it is scanned into digital form.
 The content is then digitally watermarked with a studio-assigned identifier. (In some arrangements the content is watermarked still earlier, such as at the production of dailies.) The watermark identifier is stored in a studio database, in association with metadata about the content. (Alternatively, or in addition, fingerprint data is extracted from the content, and similarly stored in the studio's database with associated metadata.) Film prints and digital cinema files are created and distributed.
 The content creation process does not end with the theatrical release materials. Dozens of other cuts and/or formats of the content may be produced, e.g., for television (in both standard definition and high definition), video on demand, airplane viewing, DVD releases, web vide in a variety of formats including MPEG2, Adobe Flash, Windows Media Format, etc., etc. The content may also be sent to outside transcoding companies (e.g., Rhozet/Harmonic) for creation of files in still other formats.
 Desirably, the watermark is of a variety that allows successive layers of watermark data to be added. In such case, a second, different, watermark is applied to each variant of the content. These identifiers, too, are stored in the studio database with other associated information (e.g., about the cut and format).
 The studio's database typically contains a great deal of proprietary information. Thus, portions of the data suitable for public dissemination (e.g., program title, synopsis, running time, watermark/fingerprint information etc.) may be sent to a different database, shown in FIG. 7 as the Program Directory Database. This is the database in FIG. 6 that collects reports identifying all the sources from which the content may be available. It may be administered by an industry association (e.g., the MPAA) or a contracted service provider (e.g., Secure Path).
 In other arrangements, suitable protection mechanisms may allow portions of the studio's internal database to be made accessible to outsiders for limited purposes. In such case, the database of FIG. 6 may comprise a federated database--with many different portions, maintained by different studios and other content creators. Combinations of external and internal databases can also be used.
 FIG. 8 further details the system from the content distributor's viewpoint (e.g., that of a television network, such as CBS). Content arrives from the movie studio at the distributor's content ingest server, accompanied by metadata. The metadata (which is typically "out-of-band" information, such as header data, or an accompanying file) details the content title, synopsis, running time, format particulars, file size, release date, etc. Both the content and the metadata are enrolled in the network's internal digital asset management system ("checked-in").
 The network adds its own metadata to the digital asset management system in association with the checked-in content, detailing internal administrative information, including when the content is scheduled for broadcast, when it is scheduled for posting on the web, internal identifiers, etc.
 In compliance with a contractual requirement with the content creator (e.g., as part of a distribution agreement), as part of the check-in process, the content distributor sends at least some of the metadata it authored and stored in its internal database--including schedule information--to the Program Directory Database, where it is stored in association with the content.
 Similarly, the content distributor can be contractually required to electronically update the Program Directory Database when there is any change to the earlier-provided information, or when new scheduling information becomes available (e.g., additional air dates, when the content is scheduled to be removed from the web, etc.).
 By such an arrangement, the Program Directory Database grows organically, with different parties contributing information as the content is first produced, and then distributed, and then as changes occur. Supplemented with information contributed by monitoring nodes remote from expected content distributors, the Program Directory Database becomes a formidable collection of information about content availability from diverse sources--all compiled automatically. Moreover, it details availability far beyond the week or ten days that are typical with known electronic program guides.
 Sometimes a content outlet may receive content but not then know the schedule by which it will be distributed. Nonetheless, the content is detected by a watermark/fingerprint detector at the outlet's content ingest point, and a record of the content as being stored at that outlet (and the date/time of detection) can be entered into the Program Distribution Database.
 Such a Program Directory Database can be used in the manners described for EPGs elsewhere in this specification. For example, the database can be consulted by cell phone applications to find--and to schedule the downloading of--desired content. If a user samples a program of interest, a quick check of the database can immediately reveal the many outlets and schedules by which full copies of the program are available. A download of the full program may be made immediately, or scheduled for a later time.
 Sometimes a user may encounter (and the user's cell phone may sample) a program seen before--such as a particular episode of a series, such as Friends or House. A software application on the cell phone that identifies the program may summon, from the Program Directory Database or elsewhere, a listing of all episodes in the sampled series, and present the listing (with program synopses) to the user. The user may not be interested in viewing the currently playing episode (since it was watched previously), but may chose to watch, or schedule for later downloading, one or more un-viewed episodes in the series (including both repeated episodes, and episodes not yet aired). Thus, an encounter with a repeated program may prompt a user to arrange for viewing of another episode of the same series. The Program Directory Database facilitates identification and location of such other episode for viewing. (In some embodiments, a file may be compiled identifying all of the episodes of a series downloaded and/or viewed by a user. This can serve as a ready reference to identify un-watched episodes of the series.)
 Known user interface paradigms from EPGs can be employed in connection with the presently described Program Directory Database. For example, a user may identify certain programs or genres as Favorites, and such programs may be featured more prominently in a user-customized presentation of the database contents.
 Some user interfaces may feature visual icons--or thumbnails--for programs, by which they are iconically represented. Thematically-consistent variants may be employed to represent different forms of content availability, e.g., web-based, streaming, download, pay, high definition, etc. For example, the same basic artwork may be used for all icons for a particular program, with different styles of borders to indicate the different variants. Such icons may be organized in folders corresponding to different programs. A folder for a particular program may also include icons representing auxiliary content that is associated with such program (e.g., information on characters, blooper reels, contests to win studio audience tickets, widgets, etc). As described elsewhere in this specification, the user may be provided an opportunity to submit feedback to the program (e.g., on plot decisions, character actions and motivations, etc); the program folder can include one or more icons that launch applications by which such feedback may be submitted.
 Desirably, differently formatted versions of the same content are merged together under a single program entry (e.g., represented as a folder) in the Program Directory Database, as presented to the user. (E.g., unlike present channel-centric EPG displays, a user would not be presented with entirely different entries for the High Definition and Standard Definition counterparts of the same broadcast, such as on ESPN and ESPN-HD.)
 In addition to folders for user-defined favorites, the user interface by which contents of the Program Directory Database are presented to the user may include folders for specials, late breaking news, and other programs of potential interest to the user that do not have dedicated folders.
 In some implementations, the information in the Program Directory Database is checked on a periodic or ongoing basis, for accuracy. For example, a monitoring service--such as offered by Nielsen--may sample local television channels to confirm that programs are available in accordance with the indicated schedules. If not, the database record can be flagged as possibly in error, and follow-up action can be taken to redress any related mistakes in the directory, and to ensure that similar errors don't recur. Such a monitoring service can likewise check web availability of content. If it finds that particular content is no longer available from a web outlet shown in the Program Directory Database to have such content, the database record can be amended accordingly.
 Watermark/fingerprint detectors may be located at other locations in the content distribution workflow--other than at public content outlets. For example, companies that offer transcoding, subtitling, and DVD authoring services may have detectors at their ingest servers--reporting content upon its receipt. These reports may be logged in the Program Directory Database, but access to these reports may be limited to the content's originator (e.g., studio). Alternatively, such detectors may report such content to a private database at the content originator.
 In still another variant, users' cell phones can generate content reports that are provided to the Program Directory Database. For example, if a user browsing the internet happens across an episode of Friends from a particular social networking web site, this fact may be reported to the Program Directory Database, and the web site can be added as an alternative outlet for the content (if not already listed). Likewise, if a user samples a television broadcast (which may be watermark-encoded with a source ID and timestamp, as described above), the content may be identified (by watermark or fingerprint), and this information reported to the Program Directory Database to check the database accuracy, and/or for audience survey purposes.
 In recent years television programming has shifted from the "lean-back" passive entertainment of decades past to the "lean-forward" entertainment that almost invites viewers to shout at the TV, such as Jerry Springer's combative offerings.
 Some emerging technologies offer the promise of 3D television, hoping to further engage viewers. However, practical problems with the user experience, such as prompting headaches, and triggering epileptic seizures, may limit the practical prospects for such physically immersive experiences.
 Better, it seems to the present applicants, are technologies that allow greater user immersion without the disorientation that attends 3D and other virtual reality experiences.
 In accordance with this aspect of the present technology, users are invited to engage with the characters, plot and environment of television and other content programs in a participatory manner, typically through a user interface provided by an associated cell phone application.
 In one particular arrangement, aspects of the program are influenced by the audience--either collectively or individually. For example, users may opt to expose certain personal profile information from their phone to the originator or distributor of the content. If a particular program is thereby found to have a viewership with an unusually large percentage of truck owners (or wine drinkers), then truck companies (or wine brands) may be accorded differential treatment in the program's production and/or advertising sponsors--shaping the content or commercial offerings to correspond to the audience. In some instances the adaptation can occur in nearly real-time, such as by advertising being inserted dynamically based on current context--just as Google's Adwords tailor ads to accompany web search results. In other arrangements, the audience profile information is provided to the program's writers, and is used to adapt the plot and/or other program features in accordance with the users' profile information.
 If a program has a high percentage of Budweiser beer drinkers, Miller Brewing Company may be willing to pay a premium ad rate to be promoted during such a program. Television and online content may take a lesson from massively multiplayer online role-playing games (MMORPGs) such as World of Warcraft, in which teams of players ("Guilds") have collective sets of talents, tools, and other assets, which determine the teams' successes and failures. Likewise with an audience for entertainment content. The composition and attributes of the audience collectively can be used to influence the content's plot, the characters' motivations and successes/failures, the advertising, etc.
 Different viewers may ally themselves with different characters in a program's cast. For example, in the program Friends, some viewers may enter information through the cell phone's user interface identifying themselves with Phoebe, others with Monica, others with Chandler, others with Ross, etc. Each program character may act, in some respects, as a proxy for the corresponding segment of the viewing audience. The audience can offer suggestions, advice, decisions, etc., which may influence the way the character responds, or other twists and turns of the plot. (The audience may urge Chandler that he is not ready to propose marriage to Monica.)
 In one particular arrangement, a program may be originally produced with several alternate plot paths (akin to the Choose Your own Adventure series of children's books). Depending on audience sentiment expressed through their cell phones, the plot may proceed in different ways (e.g., by playing one of plural different recorded segments for different portions of the program).
 In another arrangement, audience feedback is provided to the program's producers, who tailor writing of forthcoming episodes in accordance with such feedback.
 Sometimes the audience is given the opportunity to judge different program characters. In the program The Mole, for example, a cast of characters works to achieve a shared goal, but includes a double-agent saboteur--trying to foil the group, who needs to conceal his identity. At the end of each episode the audience can be polled for their assessment of who is the mole. The character with the least number of audience votes can then be removed from the cast for the next episode.
 In still another arrangement, characters in reality and other live action shows are literally informed of viewer feedback, clues, motivation, or instructions, and tailor their actions accordingly. A live comedy show may take user-submitted ideas or dilemmas as the bases for improvisational comedy sketches, which are performed after giving the comedy troop a few minutes to put together their skit.
 Great Broadway actors tell of their sense of being responsive to the particular audience in attendance at each performance. Comedians such as Lily Tomlin conspicuously adapt their acts to the particular audience before which they are performing. Although the cell phone interface does not provide quite the immediacy or intimacy of a live audience, it still allows a great step forward in enabling a performance to be adapted to the viewing audience. (With accelerometers, magnetometers, multi-touch user interface capabilities, etc., cell phones offer far richer capabilities to provide feedback than other devices available in the past, e.g., television remote controls.) New hybrids of electronic content can thereby be realized, incorporating both scripted aspects, and aspects dependent on the viewing audience.
 On-the-fly adaptation of program plot and content to reflect user feedback is becoming easier as more programming becomes wholly synthetic. That is, for programs produced with animated computer generated imagery, rather than live actors and physical sets, the plot can be dynamically configured based on real-time audience suggestions. (E.g., a Chandler-like character may miss the subway train on his way to propose marriage to a Monica-like character--delaying his arrival until after she's left for the evening--all in accordance with a CGI script adapted per audience suggestion. Or an action character can reach for either a sword or his left hip, or a mace on his right, depending on the direction that most of the audience members move their cell phones.) While popular animated Pixar productions take great lengths of time to animate and render, the lower resolutions needed for productions to be presented on televisions and cell phone screens--together with the continued exponential growth of processing power per Moore's Law, makes audience-responsive animation and rendering possible.
 In some arrangements, a program may include one or more avatars whose actions and/or motivations are established in accordance with input from the whole audience, or a portion. (E.g., content featuring a Civil War battle may include an avatar hero in the Confederate Army, responsive to input from viewers in the Confederate states, and an avatar hero in the Union Army, responsive to input from the northern states.)
 (Reference has been made to controlling motivations. A single motivation may dictate a large set of consequent actions. Thus, if a hero's motivation is to rescue the damsel, even at the price of his own life, then numerous actions in the ensuing scenes may logically follow. If the hero's motivation is instead to vanquish the opponent and live to tell about it, then a different set of actions may logically follow. Depending on circumstance, receiving audience input as to character motivation may be preferable to receiving audience input as to individual actions.)
 Names and/or locations of participating audience members can be submitted together with their content input. The program can incorporate such names into the story line. (E.g., on arriving at Monica's apartment, Chandler may note "I rode up the elevator with a guy named Tony, visiting from Portland, who said he could see my aura, and said it looked disturbed. Do you think my aura looks disturbed?") Subplots may unfold based on the input of audience participants.
 If audience avatars are included in a program, they may be given the names most common among participating audience members--increasing audience affinity to the content. Or an avatar name may be assigned otherwise, such as the name of a first viewer to correctly respond to a question, etc. Or instead of naming the avatar after an audience member, an audience member who wins a competition may be granted the privilege of assigning the avatar a name of his/her choosing.
 A plot may be scripted to include rhetorical questions, or questions between characters, to which the audience can also respond. ("I don't know if I should wear this red dress for my date tomorrow with Chandler; maybe it's too forward.") Depending on the audience response, she may or may not choose to wear the red dress (and may credit advice given by a "Tony" for her decision).
 In some cases, viewers may submit voiced (audio) instructions or other audio input. Such audio input may be incorporated into the soundtrack of the content--further increasing viewer involvement. (The soundtrack to a mob scene may comprise dozens or hundreds of superimposed audio tracks, submitted by audience members using their cell phones.)
 Naturally, audience members whose suggestions are adopted in the story as it unfolds (or whose audio is incorporated) will take pride in their involvement--giving them some bragging rights in water cooler discussions at the office, etc.
 In accordance with another aspect of the present technology, cell phones may be used to signal the "thumbs-up" or "thumbs-down" that were used to indicate gladiators' fates in ancient Rome. However, instead of the Emperor passing judgment, it is the collective audience.
 The "thumbs-up" or "thumbs-down" signals may be entered by various user interface controls, by shaking the phone while right-side-up, or by shaking it while inverted, or by other gestures or actions.
 If an audience signals approval for a first game show contestant, and disapproval for a second, the show's producers may increase the first contestant's likelihood of winning.
 Gestural use of a cell phone to signal input to an unfolding plot can be used to good effect in large audiences, such as in a theatrical auditorium screening of an action movie. The audience can be invited to thrust and jab, as with a sword, to help a hero defeat an on-screen villain. Again, the battle can unfold with different outcomes, depending on the participation of the audience (e.g., by selecting one of two earlier-produced different endings, or by animating different computer graphics sequences that are that are rendered on the fly).
 In still another aspect, mobile phones are used as input devices at live performance venues, such as concerts. The audience can use the cell phones to tell the performers what songs they want played, and suggest encore tunes. The concert promoter may publish a software application for submitting such input, and may require that users provide their email addresses (and optionally other demographic data) in order to activate the capability. By so doing, of course, the promoter gains a valuable marketing resource. The glow of cell phone screens from concert audiences may replace the glow of lighter flames to signal audience affinity for the concert performer.
 In still another aspect, the features just-described (e.g., providing user input to content programming) may be complemented by data going the other way, i.e., from the content program to the users' cell phones. The content may include watermark or other encoded data that triggers a synchronized action by the user's cell phone. This can include the various forms of auxiliary content detailed in this application and those incorporated by reference. An interplay may take place, in which user input triggers responsive action in the content, which in turn triggers responsive action in the auxiliary content, and back and forth.
 By arrangements such as the foregoing, users may involve themselves in content as it unfolds, with their actions and views influencing program actions and plot twists. Instead of the passive, lean-back viewing of decades past, or the shout-at-the-TV viewing invited by some current programming, viewers are granted control of the programming in unprecedented manners--through gestural or other interaction with their mobile phones, yielding more fully-engaging, immersive experiences.
 In accordance with a still further aspect of the present technology, users are provided straight-forward means for switching content from the small screen (e.g., a cell phone) to a nearby big screen (e.g., television display), or vice versa.
 In one form, this means comprises a user interface control that sends instructions to the destination screen, by which it can continue the user experience presently underway on the current screen (e.g., rendering of entertainment content, etc.). For web content, such as a video download from YouTube, the cell phone can send a pointer to the web site, together with state data for the video player application, e.g., detailing the current point in the video and buffered content. For a video game, the cell phone can similarly send current state information to the processor in the television computer--allowing it to resume from the current state.
 In some implementations, the transfer may be effected using the Bonjour protocol--advising the receiving processor of the information available for transfer, and inviting the receiving processor to take over.
 In some instances, rather than "push" the content from the present screen onto a different device screen, the destination device can communicate with the currently-playing device, to "pull" the content.
 In other applications, the originally displayed content may be under the control of a Java application, such as a BDJ application provided with a Blu-ray disc, or a Tru2Way application provided by a cable company's interactive service. Such content can be provided to another screen by loading a counterpart Java application on the receiving computer, and initializing its execution state in accordance with the execution state of the originating computer at the moment of the requested transfer.
 One such Java application is a program that allows viewers to play along with game shows, such as Who Wants to Be a Millionaire (in which a contestant elects how many questions to answer for doubled- or nothing-stakes), or Deal or No Deal (in which a contestant chooses a box with an unknown cash prize, from a set of boxes whose cash prizes are collectively known; the contents of other boxes are then successively revealed, indicating--by the process of elimination--prizes that are not in the chosen box; a banker offers the contestant an alternative cash deal whose value fluctuates as the process of elimination continues).
 A viewer watching such a content program can elect to receive a Java counterpart of the game (e.g., as auxiliary content--using arrangements described elsewhere in this specification). The Java version is loaded (and periodically updated) with the particular parameters of the episode being played. At any point in the episode the viewer can pause the regular presentation of the game, and try playing the game to the end with the Java application. The viewer can then compare his or her results with that of the televised contestant.
 (The original content program may be paused automatically when the Java version of the game is activated. Pausing may comprise a TiVo pause operation, which buffers ongoing content delivery on a local or remote disc. Or the original game may be delivered in an on-demand mode from a cable or online source, and pausing can be achieved simply by instructing the downloaded stream to stop, and resume later.)
 As another example, consider a person playing World of Warcraft on a home PC, who wants to continue the game while riding a bus. By operation of a content-transfer user interface control on the user's cell phone, state information about the game is transferred to the phone (together with game software, if not already present) and the player can resume action on the small screen.
 Consider also a person playing a game or watching content on a big screen, whose cell phone receives content (e.g., images) send by a friend. To better view the received content, the user may operate a control on the cell phone interface (or on the big screen interface) to automatically pause the big screen content, and display instead the information sent to the cell phone. After reviewing the images on the big screen, the user may invoke a messaging application--still on the big screen--to respond with comments back to the friend. With another operation of the UI control, the big screen then resumes the original content presentation.
 Users may want to use the big screen for many such operations, such as viewing pictures and videos, video messaging, reading, control/set-up, etc. The big screen becomes an extension of the cell phone's user interface. Content delivered to cell phones can be authored with this capability in mind, e.g., integrating a Screen Transfer button into the user interface that controls the content.
 In this and other of the detailed arrangements, screen switching can be facilitated by utilizing cloud resources for most of the associated processing (e.g., game play, user interface operation, etc.). The cloud resource receives user input from UI controls on big- and small-screen devices, and dynamically produces responsive MPEG streams that are sent to destination devices and rendered to the user. The user issuing a command on, e.g., a cell phone, quickly sees a responsive screen display--as if the cell phone is responding to the user command. In fact, it is the cloud processing that is responding; the user is simply watching a video of a remotely-authored response. By performing processing in the cloud, and using the cell phone (or big screen processor) simply as an input-output peripheral, switching screens becomes easy. The MPEG stream authored in the cloud, responsive to user input, is simply routed to a desired local device.
 Returning to the World of Warcraft game, the user controls the program as is customary. However, the user's input is sent to the cloud processor, which interacts with the game and feeds a responsive MPEG stream back to the user's PC. When the user wants to take the game onto the bus, the destination for the remotely computed MPEG stream is simply switched to the user's cell phone.
 In the case of viewing pictures (e.g. JPEG images) sent by a friend to the user's cell phone, the JPEG imagery is decompressed and presented as frames of video sent to the cell phone. A single picture is continuously rendered until the user operates a user interface control to advance to the next picture. This command is relayed to the cloud processor, which then presents the next picture as a series of video frames. When the user wants to switch to the big display for viewing, the MPEG stream is simply re-routed to the desired display.
 By such arrangements, users can switch between small- and big-screen presentations of content, and--if desired--may interrupt the usual linear unfolding of entertainment content by electing to become actively involved in content-related activities.
 Google recently announced Google Voice, which offers a number of improvements to traditional telephone systems. Vonage and Skype also offer advanced telephony features. Such features can be used in conjunction with application of the present technology.
 For example, such a service can establish rules governing how the user's phone may be employed to convey media reminders. The service can be arranged to permit delivery of television program reminders to the user only between the hours of 8 pm and 10 pm on Monday-Thursday, and between 9 am and 11 pm on Friday-Sunday, but not if the user's current location is determined to be at a movie theatre or at work, etc.
 Other features of Google Voice can be employed as well. One is locating the user. If a user sets Google Voice to ring phones at her office, residence, and beach house, and the user answers a call on the beach house phone, location data for the user is thereby generated. This information can be used with the location-based services detailed herein (as well as other location-based services).
 The voice to text transcription services offered by Google Voice can be employed to transcribe the audio of primary or auxiliary content to text, which can be provided to the user by known arrangements (email, SMS texting, FAX, etc.). For some usage scenarios, text is a better form of data than audio, as the user can skim or study different parts depending on their interest.
 Privacy concerns arise whenever user information is involved. Naturally, any implementation of the present technology should pay appropriate regard to protecting user privacy. In some arrangements the user is given the opportunity to share more or less information, thereby increasing or decreasing functionality of the different systems detailed.
 Devices other than cell phones can be used in connection with the described arrangements. In some embodiments, information and content is routed directly to such devices. In others, a cell phone receives the data, and relays it to other devices (e.g., nearby devices, or devices associated with a common network), such as by WiFi, Bluetooth or Bonjour.
 The user's profile data can include data indicating a subset of the television programming universe of interest (or not of interest) to the user. In one embodiment, this profile data takes the form of channels in the EPG (or programs in the Program Directory Database) that are to be included or excluded. (ESPN may be "in," Home Shopping Network may be "out.") Profile data for a user can also indicate social groups of which the user is a member, such as a fantasy football league or a Facebook group. Not just the fact of membership, but additional information about the group, its membership, and its activities, can be used to help identify primary and auxiliary content of potential interest. (If a user's fantasy football team includes players from four NFL teams, the user may be interested in receiving text alerts from the home TiVo system whenever any of those four teams plays.)
 Although little has been said about advertisers, they doubtless will have a role to play. One is serving in the traditional role of an underwriting sponsor for programming. Another is as a provider of auxiliary content, including applications.
 Consider a pizza chain that offers a discount application downloadable from the Apple iPhone App store. The application provides a $10 discount off a $20 pizza order when a viewer has watched certain content sponsored by the pizza chain. The cell phone senses the rendering of the sponsored content to the viewer--qualifying the viewer for the discount. Since the cell phone knows the user's location, it can identify the nearest branch of the pizza store, send a viewing confirmation to that store, and arrange for payment and delivery.
 Certain embodiments of the present technology make use of inferences. Inferences can have probabilistic results: e.g., a system may conclude there is a 60% chance the user is watching the Seahawks game, and a 40% chance the user is watching the Trailblazers game. Choices for auxiliary content can be similarly weighted. For example, three of five options presented to the user by a menu of second screen content may relate to Seahawks or football; two of the five may relate to Trailblazers or basketball.
 In some embodiments, determinations about a user's viewing activity--at home and away--are tracked and collected in a data store, e.g., a disk or memory connected to a user's home network, or maintained by a service provider, such as Nielsen, Google, or Comcast. This data store can be a hub about which auxiliary content determinations for the user are made. In some arrangements, information about auxiliary content chosen by the user can also be included. This collected data can serve as a source for profile data, and to help discern the user's activities in future contexts that may otherwise be ambiguous.
 With appropriate permissions, such information may be shared--in real time, or occasionally--with content providers and other parties, so that they can offer tailored auxiliary content for that user's consumption. In some embodiments the information is shared only with the entities involved in delivering particular content to the user. For example, information about the user's viewing of ESPN programming may be shared only with ESPN. In other embodiments the information is shared with a broader class of entities. This latter arrangement, for example, can allow CBS, NBC, ABC and FOX to offer auxiliary content corresponding to an ESPN football game.
 (Such collected information may also be shared with audience measurement enterprises.)
 Different networks may all have different strategies for the second screen. Fox, NBC, ESPN may all have different auxiliary content for similar primary content.
 While the specification discusses estimating a program that the user may be watching (or may watch in the future), several programs can be similarly estimated. If the user is asked for confirmation, she may identify one of several as being watched.
 While this specification earlier noted its relation to the assignee's previous patent filings, it bears repeating. These disclosures should be read in concert and construed as a whole. Applicants intend that features in each be combined with features in the others. Thus, for example, arrangements employing widget-related technology as detailed in application 61/150,235 may be implemented to also include features and arrangements detailed in the present application--and vice versa. Audio sampling an airport television monitor to trigger a DVR back home to record the same or a preceding program, as detailed in application Ser. No. 12/271,772, can likewise query a crowd-sourced database to identify related auxiliary content as detailed in the present specification. Pushing various auxiliary content to a cell phone through which a user can scroll with arrow keys, as detailed in application Ser. No. 12/484,115, can be employed in systems using the present application's circumstance-based guess about the content to which the user is currently being exposed, as detailed in the present application. The referral of some content recognition tasks, or component tasks, to outside service providers--possibly on a reverse auction basis, as detailed in application Ser. No. 12/484,115--can similarly be employed in embodiments of the presently-described technology. Etc., etc. Thus, it should be understood that the methods, elements and concepts disclosed in the present application be combined with the methods, elements and concepts detailed in those related applications. While some have been particularly detailed in the present specification, many have not--due to the large number of permutations and combinations. However, implementation of all such combinations is straightforward to the artisan from the provided teachings.
 DVRs are usually home-based devices. But they need not be so. Embodiments of the present technology can use all manner of recording devices--wherever located. (Cablevision is offering a consumer DVR service where the actual recording is done at a head-end in a cable distribution system.)
 While FIG. 1 shows the second screen auxiliary content as being conveyed separately than the primary content, in other arrangements they can be conveyed together, or using the same distribution system.
 In some implementations, the user's proximity to other people can be used in estimating the user's activity. For example, if the user is in proximity to buddies from an after-work basketball league, this factor may make it more likely that the user is watching a basketball game (if the month is March) or a football game (if the month is November). In contrast, if the user is in proximity with his wife, and it is a Monday--Thursday evening, this factor may suggest that the user is watching the Daily Show on Comedy Central. Proximity can be sensed electronically, e.g., by Bluetooth signals, by comparison of location data, etc.
 As indicated, the meaning of physical proximity depends on the requirements of a particular implementation. Physically proximate can mean within a certain distance (e.g., 10 yards, or 100 yards), within a common dwelling, within line of sight, served by a common network, within range of a short range wireless service like WiFi or Bluetooth, etc.--depending on the application.
 The specification refers to television programs. But this is a shorthand that is meant to encompass any video content--regardless of how produced or delivered. For example, a television program can be a traditional program--distributed simultaneously across multiple different networks to plural consumers. Or it can be content distributed using other models, such as web casts, YouTube, Hulu, Video on Demand (e.g., Netflix), Boxee, DVD, theatrical presentations, etc.
 Looking forward, content programmers may create libraries of enhanced media experiences, each customized to individual users, comprising a basic content theme (e.g., a basketball game) in which complementary experiences (auxiliary content) are dynamically selected by and navigated by the user. The paradigm of a television screen and a cell phone may be eclipsed by more immersive rendering systems and by more capable user interfaces. One user may choose a Howard Cosell avatar to narrate a Jets football game, and may engage the avatar in interactive spoken dialog to clarify particular points. Another may simply chose sideline commentary by a graying Joe Namath.
 Reference was made to a Program Directory Database. Once the data is compiled by the detailed automated techniques, it can be presented, used and disseminated according to techniques discussed elsewhere in this specification in connection with EPGs, and otherwise--as known from existing EPG prior art. Prior art EPG technologies are not detailed in this specification; the reader is referred to the existing literature for further information. (This literature includes Davis et al U.S. Pat. Nos. 5,559,548, 5,576,755, 5,585,866, 5,589,892, 5,635,978, 5,781,246, 5,822,123, 5,986,650, 6,016,141, 6,141,488, 6,275,268, 6,275,648, 6,331,877, 6,418,556, 6,604,240, and 6,771,317, and U.S. Pat. No. 7,263,202 to the present inventors concerning use of watermarking in connection with EPGs.)
 While the present technology is described in the context of providing auxiliary content to complement primary video content, the same principles are applicable elsewhere, e.g., in other devices that respond to circumstances and/or their environment. Thus, for example, auxiliary content can be associated with any object, including physical objects. A user taking a picture of the Eiffel Tower, or a carton of milk, may be presented with a menu of associated content using principles detailed herein.
 It will be recognizing that certain of the above-detailed arrangements are specialized cases of a larger concept--technologies that help present content responsive to a user's environment.
 Some researchers foresee the day when all of our daily experiences are captured in digital form. Indeed, Gordon Bell at Microsoft has compiled a digital archive of his recent existence through his technologies CyberAll, SenseCam and MyLifeBits. Included Bell's archive are recordings of all telephone calls, video of daily life, captures of all TV and radio consumed, archive of all web pages visited, map data of all places visited, polysomnograms for his sleep apnea, etc., etc., etc. (For further information see, e.g., Bell, A Digital Life, Scientific American, March, 2007; Gemmell, MyLifeBits: a personal database for everything, Microsoft Research Technical Report MSR-TR-2006-23; Gemmell, Passive Capture and Ensuing Issues for a Personal Lifetime Store, Proceedings of The First ACM Workshop on Continuous Archival and Retrieval of Personal Experiences (CARPE '04), pp. 48-55; Wilkinson, Remember This, The New Yorker, May 27, 2007. See also the other references cited at Gordon's Bell's Microsoft Research web page, and the ACM Special Interest Group web page for CARPE (Capture, Archival & Retrieval of Personal Experiences) web page.)
 A more practical example is a cell phone that captures aspects of a user's daily experiences through frequent sampling of audio (e.g., five thousand samples per second, continuously; or ten thousand samples per second for sequences of twelve seconds every minute, etc.). These samples can be sent to the user's home for further query at the user's explicit request, or they may accompany the user and provide data on which other operations can be based.
 Consider a user who hears a song of interest while at a restaurant. At a later time she physically or wirelessly links her cell phone with her laptop, which runs the Google Toolbar. (Or the cell phone may itself run the Google Toolbar.) While the Google Toolbar maintains a history of past searches, the cell phone provides a history of past experiences. Using a user interface for this task provided by the Google Toolbar, the user quickly navigates through audio samples from the day (e.g., by timestamp, GPS location tag, etc.) and finds the sample taken at the restaurant. The Google Toolbar processes the identified audio and returns metadata for the song, such as title name, artist and album. However, unlike competing services (such as Shazam), the sampled history allows the user to mine past experiences--in some cases investigating captured information that didn't become of interest until later.
 In another arrangement all of the sampled audio is provided to Google (as it is captured, or later). Google initiates searches, and annotates the audio data with (or otherwise provides) results, such as metadata; speech-to-text data; links to Wikipedia and other web resources corresponding to audibly discernible words--and concepts abstracted from the words by NLP, etc. When the user later reviews the audio data, this enhancement information is immediately available.
 Crowdsourcing, and location data can be employed to good effect. For example, Google may identify a dozen other patrons who were in the restaurant at the same time as the user, by reference to GPS data and timestamps. Audio captured by those patrons can be considered in conjunction with audio captured by the user, to more completely characterize the user's audio environment (e.g., an uninterrupted stream of audio may be assembled from the occasional audio samples captured by the different phones). Google can analyze this augmented patchwork of audio to yield more and/or better information, and make this information available to users, e.g., in accordance with the respective time period that each was in the restaurant.
 In another implementation, Google may make available results from analysis of other patrons' audio data--either searches that the patrons expressly requested, or analyses that Google conducted autonomously. If a person at the next table ordered a chocolate souffle, Google's search of the term--which it recognized and combined with the restaurant name in one of its data mining efforts--may reveal the restaurant's recipe for that dessert as published in Gourmet magazine three years ago. Such information may be included among the results presented to the user, even though it was based on audio captured at another patron's table. In like fashion, the restaurant's menu may be reconstructed from the repeatedly-spoken entree names--contextually recognized by the analysis software (e.g., as following the audio clue "May I take your order?") and made available to all users known--by GPS data--to have visited the restaurant (whether or not they captured audio there).
 In still other arrangements, captured audio is fed to Google continuously, and analyzed immediately. Google streams the results of its analyses back to the users' cell phones, where they are buffered for review. (Some analyses may take longer than others, so the returning data flow may not be strictly chronological, but the returning data may each be associated with a timestamp indicating the excerpt of audio to which it corresponds, so the information can be presented in appropriate order.) At any point a user can scroll back through their experience (perhaps using a user interface suited for temporally arranged data, such as the "cover flow" interface used by Apple in the iPod and detailed in its patent publication 20080174570) to examine captured information, and to review corresponding information returned by Google.
 (In the arrangements just-detailed, the fact that the patrons are in a common environment (i.e., the restaurant) can be ascertained by looking up their respective latitude/longitude coordinates in a geolocation database, such as the GeoPlanet service noted above. To a low level of functional granularity, e.g., to the level of street address or business name, the patrons' latitude/longitude coordinates all correspond to the same location.)
 Various references have been made to Bonjour. Bonjour is Apple's trade name for its implementation of Zeroconf--a service discovery protocol. Bonjour locates devices on a local network, and identifies services that each offers, using multicast Domain Name System service records. This software is built into the Apple MAC OS X operating system, and is also included in the Apple "Remote" application for the iPhone, where it is used to establish connections to iTunes libraries via WiFi. (TiVo uses Bonjour to locate digital video recorders and shared media libraries.)
 Bonjour services are implemented at the application level largely using standard TCP/IP calls, rather than in the operating system. Apple has made the source code of the Bonjour multicast DNS responder--the core component of service discovery--available as a Darwin open source project. The project provides source code to build the responder daemon for a wide range of platforms, including Mac OS X, Linux, *BSD, Solaris, and Windows. In addition, Apple provides a user-installable set of services called Bonjour for Windows, as well as Java libraries.
 As indicated, Bonjour can be employed to serve various functions in implementations of the present technology. For example, a DVR can use Bonjour to periodically (e.g., every second or every several seconds) send out on a home network subnet one or more packets identifying the programming it is currently rendering (or recording), and identifying auxiliary content corresponding to that programming. It may also identify its own location, its registered user(s), and functions/services it offers, as well as detailing other programming choices that are currently available according to EPG data, and according to listings of previous recordings. These Bonjour broadcasts all include the DVR's IP address, so that responding systems can request from the DVR further information or content. Likewise, a cell phone can similarly transmit information identifying its status, the content it is rendering, its location, its available functions/services, profile data of the user, etc.
 Other software can alternatively, or additionally, be used to exchange data between devices. Examples include Universal Plug and Play (UPnP) and its successor Devices Profile for Web Services (DPWS). These are other protocols implementing zero configuration networking services, through which devices can connect, identify themselves, advertise available capabilities to other devices, share content, etc.
 The artisan is presumed to be familiar with such software tools.
 It will be recognized that certain embodiments of the present technology allow plural viewers to have individual viewing experiences on individual screens, without interfering with a collective group viewing experience on a shared screen. The net result is an enhanced social experience, in which the individuals can contribute different perspectives to a robust group experience.
 Having described and illustrated the principles of our inventive work with reference to illustrative examples, it will be recognized that the technology is not so limited.
 For example, while reference has been made to cell phones, it will be recognized that this technology finds utility with all manner of devices--both portable and fixed. PDAs, organizers, portable music players, desktop computers, wearable computers, servers, etc., can all make use of the principles detailed herein. Particularly contemplated cell phones include the Apple iPhone, and cell phones following Google's Android specification (e.g., the G1 phone, manufactured for T-Mobile by HTC Corp.). The term "cell phone" should be construed to encompass all such devices, even those that are not strictly-speaking cellular, nor telephones.
 (Details of the iPhone, including its touch interface, are provided in Apple's published patent application 20080174570.)
 For expository convenience, concepts noted in this specification are usually described singly. However, these concepts can be combined in nearly unlimited combinations (including concepts detailed in the incorporated-by-reference documents), e.g., so that a cell phone or system can employ multiple of the described features detailed. Such combinations expressly fall within the disclosure of this application.
 While the specification and drawings describe data as being stored in certain devices, this is illustrative only. Data can be stored anywhere (even in "cloud" storage), and made available whenever and wherever needed. Similarly, various operations are described as being performed by particular devices. However, processing too can be performed anywhere, and results made available wherever needed. Thus, references to a cell phone performing an operation, or data being stored in a DVR, are illustrative only. Other arrangements can of course be used.
 The present assignee has published a great deal of information about related systems and technologies in the patent literature--a body of work with which the artisan is presumed to be familiar. Included are U.S. Pat. Nos. 6,590,996, 6,947,571, and published patent application 20070156726.
 While certain arrangements employ watermark technologies for content identification or signaling, the same or similar functionality can often be realized with fingerprint-based approaches, or out-of-band technologies (e.g., VBI signaling). In some implementations, bar coding or other overt symbologies, RFID chips, and other identification technologies may be employed.
 Although disclosed as complete systems, subcombinations of the detailed arrangements are also separately contemplated.
 While this specification has detailed particular ordering of acts and particular combinations of elements, in the illustrative embodiments, it will be recognized that other contemplated methods may re-order acts (possibly omitting some and adding others), and other contemplated combinations may omit some elements and add others, etc.
 The design of cell phones and other devices referenced in this disclosure is familiar to the artisan. As indicated above, each typically includes one or more processors, one or more memories (e.g. RAM), storage (e.g., a disk or flash memory), a user interface (which may include, e.g., a keypad, a TFT LCD or OLED display screen, touch or other gesture sensors, a camera or other optical sensor, a microphone, etc., together with software instructions for providing a graphical user interface), interconnections between these elements (e.g., buses), and one or more interfaces for communicating with other devices (which may be wireless, such as GSM, CDMA, W-CDMA, CDMA2000, TDMA, EV-DO, HSDPA, WiFi, WiMax, or Bluetooth, and/or wired, such as through an Ethernet local area network, a T-1 internet connection, etc).
 The processes and system components detailed in this specification may be implemented as instructions for computing devices, such as instructions for a variety of general purpose programmable processors including microprocessors (e.g., the ARM series of 32-bit RISC processors), graphics processing units (GPUs), digital signal processors (e.g., the Texas Instruments TMS320 series of devices), etc. These instructions may be implemented as software, firmware, etc. These instructions can also be implemented in various forms of processor circuitry, including programmable logic devices, FPGAs (e.g., the Xilinx Virtex series devices), and application specific circuits--including digital, analog and mixed analog/digital circuitry. Execution of the instructions can be distributed among processors and/or made parallel across processors within a device or across a network of devices. Transformation of content signal data may also be distributed among different processor and memory devices. References to "processors" or "modules" should be understood to refer to functionality, rather than requiring a particular form of implementation.
 Software instructions for implementing the detailed functionality can be readily authored by artisans from the descriptions provided herein, e.g., written in C, C++, Visual Basic, Java, Python, Tcl, Perl, Scheme, Ruby, etc. Cell phones, DVRs and other devices according to the present technology can include software modules for performing the different functions and acts.
 Typically, each device includes operating system software that provides interfaces to hardware devices and general purpose functions, and also includes application software which can be selectively invoked to perform particular tasks desired by a user. Known browser software, communications software, and media processing software can be adapted for many of the uses detailed herein. Software is commonly stored as instructions in one or more data structures conveyed by tangible media, such as magnetic or optical discs, memory cards, ROM, etc. Some embodiments may be implemented as embedded systems--a special purpose computer system in which the operating system software and the application software is indistinguishable to the user (e.g., as is commonly the case in basic cell phones). The functionality detailed in this specification can be implemented in operating system software, application software and/or as embedded system software.
 Different of the functionality can be implemented on different devices. For example, in a system in which a cell phone communicates with a remote server, different tasks can be performed exclusively by one device or the other, or execution can be distributed between the devices. Identifying content is but one example of such a task. Thus, it should be understood that description of an operation as being performed by a device is not limiting but exemplary; performance of the operation by another device, or shared between devices, is also contemplated.
 Operations need not be performed exclusively by specifically-identifiable hardware. Rather, some operations can be referred out to other services (e.g., cloud computing), which attend to their execution by still further, generally anonymous, systems. Such distributed systems can be large scale (e.g., involving computing resources around the globe), or local (e.g., as when a portable device identifies nearby devices through Bluetooth communication, and involves one or more of the nearby devices in a task).
 It will be recognized that the detailed processing of content signals (e.g., image signals, audio signals, etc.) includes the transformation of these signals in various physical forms. Images and video (forms of electromagnetic waves traveling through physical space and depicting physical objects) may be captured from physical objects using cameras or other capture equipment, or generated by a computing device. Similarly, audio pressure waves traveling through a physical medium may be captured using an audio transducer (e.g., microphone) and converted to an electronic signal (digital or analog form). While these signals are typically processed in electronic and digital form to implement the components and processes described above, they may also be captured, processed, transferred and stored in other physical forms, including electronic, optical, magnetic and electromagnetic wave forms. The content signals are transformed in various ways and for various purposes during processing, producing various data structure representations of the signals and related information. In turn, the data structure signals in memory are transformed for manipulation during searching, sorting, reading, writing and retrieval. The signals are also transformed for capture, transfer, storage, and output via display or audio transducer (e.g., speakers).
 Reference was made to GPS data. This should be understood as a short-hand for any location-related information; it need not be derived from the Global Positioning System constellation of satellites. For example, another technology that is suitable for generating location data relies on radio signals that are that commonly exchanged between devices (e.g., WiFi, cellular, etc.). Given several communicating devices, the signals themselves--and the imperfect digital clock signals that control them--form a reference system from which both highly accurate time and position can be abstracted. Such technology is detailed in laid-open international patent publication WO08/073,347. The artisan will be familiar with several other location-estimating techniques, including those based on time of arrival techniques, and those based on locations of broadcast radio and television towers (as offered by Rosum) and WiFi nodes (as offered by Skyhook Wireless, and employed in the iPhone), etc.
 While geolocation data commonly comprises latitude and longitude data, it may alternatively comprise more, less, or different data. For example, it may include orientation information, such as compass direction provided by a magnetometer, or inclination information provided by gyroscopic or other sensors. It may also include elevation information, such as provided by digital altimeter systems.
 Reference was made to touchscreen interfaces--a form of gesture interface. Another form of gesture interface that can be used in embodiments of the present technology operates by sensing movement of a cell phone--by tracking movement of features within captured imagery. Further information on such gestural interfaces is detailed in Digimarc's U.S. Pat. No. 6,947,571.
 As noted, watermark technology can be used in various embodiments. Technology for encoding/decoding watermarks is detailed, e.g., in Digimarc's U.S. Pat. Nos. 6,614,914, 6,590,996 and 6,122,403; in Nielsen's U.S. Pat. Nos. 6,968,564 and 7,006,555; and in Arbitron's U.S. Pat. Nos. 5,450,490, 5,764,763, 6,862,355, and 6,845,360.
 Digimarc has various other patent filings relevant to the present subject matter. See, e.g., patent publications 20070156726, 20080049971, and 20070266252, and pending application Ser. No. 12/125,840 by Sharma et al, filed May 22, 2008. Content fingerprinting can also be used in various embodiments. Examples of audio fingerprinting are detailed in patent publications 20070250716, 20070174059 and 20080300011 (Digimarc), 20080276265, 20070274537 and 20050232411 (Nielsen), 20070124756 (Google), U.S. Pat. No. 7,516,074 (Auditude), and U.S. Pat. No. 6,990,453 and U.S. Pat. No. 7,359,889 (both Shazam). Examples of image/video fingerprinting are detailed in patent publications U.S. Pat. No. 7,020,304 (Digimarc), U.S. Pat. No. 7,486,827 (Seiko-Epson), 20070253594 (Vobile), 20080317278 (Thomson), and 20020044659 (NEC).
 The figures are meant to be exemplary and not limiting. For example, they sometimes show multiple databases, when a single can be used (and vice-versa). Likewise, some links between the depicted blocks are not shown--for clarity's sake.
 Contextual data can be used throughout the detailed embodiments to further enhance operation. For example, a process may depend on whether the originating device is a cell phone or another type of device; whether the ambient temperature is 30 or 80; the location of, and other information characterizing the user; etc.
 It is impossible to expressly catalog the myriad variations and combinations of the technology described herein. Applicants recognize and intend that the concepts of this specification can be combined, substituted and interchanged--both among and between themselves, as well as with those known from the cited prior art. Moreover, it will be recognized that the detailed technology can be included with other technologies--current and upcoming--to advantageous effect.
