摘要： Alignment of an antenna and a polarizer for the antenna are automatically adjusted and the frequency setting of a frequency-tunable receiver is automatically adjusted while receiving a broadcast communication signal that is forward-error-correction coded by processing the forward-error-correction code of the received signal to measure a channel-bit-error-rate-affected parameter for the received signal; by realigning the antenna and the polarizer from their respective initial positions in response to the measured parameter until the measured parameter is minimized; and by retuning the receiver from its initial frequency setting in response to the measured parameter until the measured parameter is minimized. A Viterbi decoder processes the forward-error-correction code of the received signal to compute path metrics affected by the bit-error rate of the received signal and normalizes the computed path metrics; and a counter counts the normalizations over fixed intervals to measure a path metric normalization rate as the measured parameter.

摘要： A field upgradeable security system deciphers signals received from a communication network. An information processor includes a receptacle for receiving a replaceable security element. The replaceable security element generates a working key necessary to the operation of the information processor. The working key is communicated to the information processor encrypted under a secret key. The information processor decrypts the encrypted working key for use in deciphering a received communication signal. Additional layers of encryption can be added to the communications between the information processor and security element to increase the level of security.

摘要： A system for scrambling a video signal having a plurality of horizontal lines, each of which includes a video information portion and a non-video information portion. The scrambling system includes a memory; means for storing the video information portion of each video signal line in the memory; and means for forming scrambled horizontal lines by retrieving each of a plurality of said stored video information lines in a plurality of segments preceded by a non-video segment and separated by non-video segment(s). The retrieval means include means for varying the respective durations of the retrieved video information segments in individual scrambled horizontal lines in accordance with an encryption keystream; and means for varying the total duration of the non-video segments for individual scrambled horizontal lines in accordance with a predetermined timing pattern. A complementary descrambling system also is disclosed.

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： 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 method is provided by which a client device obtains authorized access to content delivered over a content delivery network. The method includes receiving an entitlement management message (EMM). The EMM includes at least one cryptographic key and a device registration server certificate ID (DRSCID) identifying a currently valid device registration server (DRS) public key certificate. The DRSCID obtained from the EMM is compared to a stored DRSCID value. An entitlement control message (ECM), which includes an encrypted traffic key for decrypting content, is received. If the DRSCID obtained from the EMM is determined to match the stored DRSCID, the traffic key is decrypted with the cryptographic key or a key derived from the cryptographic key to thereby access the content.

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.
