| Class / Patent application number | Description | Number of patent applications / Date published |
|---|
| 380240000 | Including addressed decoder control signal | 6 |
| 20090154698 | VIDEO PROCESSING SYSTEM FOR SCRAMBLING VIDEO STREAMS WITH DEPENDENT PORTIONS AND METHODS FOR USE THEREWITH - A video processing system includes a video encoder that encodes a video signal into a contiguous video stream having an independent portion and a dependent portion that requires the independent portion for decoding. A scrambling module scrambles the contiguous video stream to produce a scrambled video stream by scrambling the independent video portion and leaving the dependent portion unscrambled. | 06-18-2009 |
| 380241000 | Having program ID or authorization | 3 |
| 20080247544 | Authentication in an Audio/Visual System Having Multiple Signaling Paths - A method and structure for authentication in a system having devices capable of communicating via multiple signal paths. Authentication is carried out between first and second devices. A first device communicates with a second device over a first data signaling path of an interface between the first and second devices in a first portion of an authentication process. A second device communicates with the first device over a second data signaling path of the interface between the first and second devices in a second portion of the authentication process. | 10-09-2008 |
| 20080273699 | SYSTEM FOR CONTROLLING THE TRANSMISSION OF MASS NOTIFICATIONS - A system for authorizing the mass distribution of a digital message includes a CPU configured to prepare in digital form a message from an initiator, and to distribute the message to a plurality of recipients and/or recipient contact devices. The CPU is further configured to associate with the message data sets selected by the initiator, and: To compare the data sets with a set of authorization criteria, whereby the CPU determines if an authorization threshold has been crossed. To distribute the message if no authorization threshold has been crossed. To wait for authorization if any authorization threshold has been crossed, and, thereafter: to distribute the message if authorization is provided; or to not distribute the message if authorization is not provided. | 11-06-2008 |
| 20150071436 | Restricting Information Requested By An Application - The technology includes a method for a computing device (console) to restrict transferring information to others on the Internet. A user does not have to explicitly make a choice of having the console restrict the transferring of information to an external computing device because the technology determines that such information cannot be transferred. When an application is loaded, a NSAL is read to determine whether the application will communicate with an external computing device. A NSAL may include authorized network addresses that an application may communicate with when executing on a computing device. When the NSAL does not include any network addresses, there is no need to obtain consent from a user regarding transferring the information externally because the application does not have the capability to do so. When one or more network addresses are includes in a NSAL, consent from a user is obtained. | 03-12-2015 |
| 380242000 | Having command signal for receiver | 2 |
| 20090190757 | EFFICIENT BROADCAST ENTITLEMENT MANAGEMENT MESSAGE DELIVERY MECHANISM USING A SCHEDULED DELIVERY WINDOW - Systems and methods include broadcasting an entitlement management message (EMM) in a communication system using a scheduled delivery window. The systems and methods including receiving a EMM broadcast window from a distribution system, listening for the EMM during the EMM broadcast window, and receiving the EMM from the distribution system during the EMM broadcast window. | 07-30-2009 |
| 20120114121 | METHOD OF TRANSMITTING AND RECEIVING CONTENT - Provided is a method of transmitting and receiving content. The method includes (a) transferring, at a content server, a service key to a mobile terminal, (b) transferring, at the content server, a number to the mobile terminal, (c) scrambling, at the content server, content and transferring the scrambled content to the mobile terminal, (d) updating, at the mobile terminal, the service key on the basis of the number, and (e) descrambling, at the mobile terminal, the scrambled content using the updated service key. | 05-10-2012 |
