20080247730 | SYSTEM AND METHOD FOR INTERNET ACCESS TO A PERSONAL TELEVISION SERVICE - A communication system and a family of methods for remote access to personal television service are disclosed. According to this invention, a remote personal TV service center provides centralized program guide information. A user may access to the personal TV service center through a digital video recorder which is connected to the personal TV service center via telephone modem or a network server. A user may access to the personal TV service center through a remote computer terminal or a personal digital assistant which is connected to a computer network. The user selects program events and programs the digital video recorder by using a graphical user interface installed in the front panel of the digital video recorder in case of local programming, or using a similar GUI which is incorporated into the Web pages presented to remote users by a Web server in case of remote programming. The media stream stored in one digital video recorder may be transferred to another digital video recorder. For data security protection during data transfer, all communication are authenticated and encrypted. | 10-09-2008 |
20090240692 | HIERARCHICAL TAGS WITH COMMUNITY-BASED RATINGS - A method for generating and maintaining hierarchical tags with community-based ratings is provided. Tags for media streams are organized into a hierarchical format. Users may select tags from the hierarchical tag database that describes a particular multimedia content. If the user is unable to locate a desired tag, the user may submit a new tag. Upon submission of the new tag, a librarian approves the tag before storing and placing the tag in the hierarchical tag database. Users are also able to rate the quality of the association between the tag and the multimedia content. If a tag is rated low, the tag may be removed from the hierarchical tag database. If the tag is rated highly, display of the tag in a list of tags becomes more prominent. | 09-24-2009 |
20090256718 | MULTIMEDIA MOBILE PERSONALIZATION SYSTEM - A multimedia mobile personalization system provides a remote control that detects a user's electronic tag, e.g. an RFID tag. The remote control notifies a multimedia device of the user's identity. The multimedia devices tailors it operations to the user's preferences stored locally. Multimedia content such as broadcast or recorded television programs, music play lists, and the like could be sorted, displayed, or restricted, depending on the user identifier. | 10-15-2009 |

20090316895 | CONDITIONAL ACCESS SYSTEM AND METHOD FOR PREVENTION OF REPLAY ATTACKS - In a conditional access system, a headend transmits content to one or more receivers in encrypted transport streams. The system provides a multi-layer security architecture, rendering the system resistant to key replay attacks; if one layer is circumvented, subsequent layers remain intact. A first layer prevents unencrypted keys from being recorded by shielding the unencrypted keys from users and encrypting the path from the receiver's conditional access module to the transport decryption module; a second layer prevents a key recorded on one receiver from being played back to the transport decryption module on a second receiver; a third layer prevents a user from decrypting transport streams without the encryption module by encrypting the stream a second time prior to being passed through any user-accessible memory or processor. | 12-24-2009 |
20100042833 | DATA ANONYMITY SYSTEM - A method and system for providing data anonymously is provided. The method involves receiving an encrypted operator match ID by a client device from a first entity, where the encrypted operator match ID is encrypted using a first encryption key; decrypting the encrypted operator match ID using a first decryption key, associated with the first encryption key, by the client device to obtain a decrypted operator match ID; encrypting the decrypted operator match ID using a second encryption key by the client device to obtain a re-encrypted operator match ID; and sending the client device usage information with the re-encrypted operator match ID by the client device to a second entity through an anonymous channel, where the second entity decrypts the re-encrypted operator match ID using a second decryption key, associated with the second encryption key, to obtain the operator match ID. | 02-18-2010 |
20100319014 | Multimedia Mobile Personalization System - A multimedia mobile personalization system allows a user to record and play multimedia content on a set top box at a location other than his home using the user's preferences from his home DVR. | 12-16-2010 |

20130294754 | Distributed Database Management System - A distributed database management system provides a central database resident on a server that contains database objects. Objects, e.g., program guide data, to be replicated are gathered together into distribution packages called “slices,” that are transmitted to client devices. A slice is a subset of the central database which is relevant to clients within a specific domain, such as a geographic region, or under the footprint of a satellite transmitter. The viewer selects television programs and Web content from displayed sections of the program guide data which are recorded to a storage device. The program guide data are used to determine when to start and end recordings. Client devices periodically connect to the server using a phone line and upload information of interest which is combined with information uploaded from other client devices for statistical, operational, or viewing models. | 11-07-2013 |
