摘要： Two or more set-top boxes are installed in a household. A communications link, preferably a physical link, is provided between or among the set-top boxes. One of the boxes is designated as a “master” box while the other box or boxes are “slaves.” The slave box will use the communications link to communicate in a secured and encrypted manner with the master box. If that communication is severed, e.g., if an attempt is made to move the slave box to another household to provide unauthorized service in that household, the slave box will stop working when it can no longer communicate with the master box.

摘要： A client device implements a media player and a proxy application. The media player controls playback of media content on the client device. The proxy application is implemented to request a playlist from a media server, where the playlist corresponds to the media content. The proxy application receives the playlist from the media server, and the playlist includes encryption key reference parameters to obtain an encryption key. The proxy application modifies the playlist to include local encryption key access parameters for the media player, and the modified playlist is communicated to the media player. The proxy application can then receive a request for the encryption key from the media player that utilizes the local encryption key access parameters included in the modified playlist, and the proxy application securely communicates the encryption key to the media player.

摘要： A secure Internet Protocol (IP) telephony system, apparatus, and methods are disclosed. Communications over an IP telephony system can be secured by securing communications to and from a Cable Telephony Adapter (CTA). The system can include one or more CTAs, network servers, servers configured as signaling controllers, key distribution centers (KDC), and can include gateways that couple the IP telephony system to a Public Switched Telephone Network (PSTN). Each CTA can be configured as secure hardware and can be configured with multiple encryption keys that are used to communicate signaling or bearer channel communications. The KDC can be configured to periodically distribute symmetric encryption keys to secure communications between devices that have been provisioned to operate in the system and signaling controllers. The secure devices, such as the CTA, can communicate with other secure devices by establishing signaling and bearer channels that are encrypted with session specific symmetric keys derived from a symmetric key distributed by a signaling controller.

摘要： In embodiments of an object model for domain-based content mobility, a client object model architecture (146) is configured for scalable and adaptive implementation to interface a mobile client device (128) with a media server (126) for wireless, secure download of media content (136) to the mobile client device. The client object model architecture can be implemented for domain-based control of a software application that invokes a media player (142) on the mobile client device, and interfaces with the media server that communicates the media content to the mobile client device. The client object model architecture also controls domain discovery of the media server, domain-based registration of the mobile client device with the media server, channel change requests, and solicited and unsolicited channel changes.

摘要： A content moving device which enables providing content stored on a first user device, such as a DVR, in a first format and resolution to be provided to a second user device, such as a portable media player (PMP) in a second format and resolution. The content moving device identifies content on the first user device as candidate content which may be desired by the PMP and receives the candidate content from the DVR. The content moving device transcodes the candidate content at times independent of a request from the PMP for the content. The content moving device may provide a list of available transcoded content to the PMP for selection, and provide selected content to the PMP. The content moving device may also provide information relating to any protection schemes of the content provided to the PMP, such as DRM rights and decryption keys. The content moving device performs the often computationally intense and time consuming transcoding of user content to enable the user to move content between different user devices in a convenient manner.

摘要： The present invention discloses an apparatus and method for delivering a revocation list over a one-way broadcast network to receivers with limited memory capabilities. In one example, the revocation list is partitioned to form a first certificate revocation list (CRL) sequence if the number of entries in the revocation list exceeds a predetermined value. Individual identification numbers belonging to a first identification number series are subsequently assigned to partitions of the first CRL sequence. Afterwards, the first CRL sequence is interleaved into a first content transport stream.

摘要： A consumer set-top terminal and method that receives and stores digital programming services such as television programs for subsequent playback by the user in a manner analogous to a conventional video cassette recorder (VCR). An interface allows the terminal's user to control a transcoding proces based on the desired quality level for the transcoded data, e.g., high, medium or low. The transcoding is provided without the expense and complexity of a full encoder. By performing transcoding at the terminal, the bit rate of the data can be reduced sufficiently to allow economical storage at the terminal. Moreover, the user can set the quality level to be different for different programs, different parts of the same program, or for different channels. The user input can be received via an interface, such as an on-screen display, which is optionally integrated with electronic program guide data. The user input can be established beforehand as well.
