摘要： The present disclosure is directed to a system and method of correcting video data errors. In a particular embodiment, the method includes receiving a stream of data packets at a re-generator of an Internet Protocol (IP) video transport stream. The stream of data packets includes a plurality of IP media packets and a plurality of forward error correction (FEC) packets. The method also includes determining an error profile of an error within the plurality of IP media packets. The method includes identifying one of the plurality of FEC packets, where the identified FEC packet is associated with an error correction code corresponding to the error profile. The method also includes selecting an inverse FEC function from a plurality of inverse FEC functions. The selected inverse FEC function corresponds to the identified FEC packet.

摘要： A system for transporting content to subscriber premises includes a centralized content repository, a subscriber unit, and a network connecting the subscriber unit and repository. The content can be video, image, or other files and the network can include a digital subscriber line (DSL) link. The repository stores higher quality parts of decomposed content files. The subscriber unit locally stores lower quality parts of the content files corresponding to the higher quality parts in the repository. The lower quality parts can be downloaded to the subscriber unit during off-peak hours. During operation, a subscriber selects a locally stored file. In response to the selection, the repository downloads at least one of the higher quality parts corresponding to the selected file to be combined with one of the lower quality parts stored by the subscriber unit for real-time presentation of the content.

摘要： Systems and methods for providing direct broadcast satellite (DBS) and digital subscriber line (DSL) video services to multiple display devices are disclosed. Generally the disclosed system receives a plurality of DBS channels and DSL content. The system receives a first user-initiated video selection and generates a first television signal based on the first user-initiated video selection. The first television signal combines video from at least one DBS channel and video from DSL content for simultaneously displaying at least a portion of the video from at least one DBS channel and at least a portion of the video from the DSL content on a display device. The first television signal is then transmitted to a first display device. Additionally, the system receives a second user-initiated video selection, generates a second television signal based on the second user-initiated video selection, and transmits the second television signal to a second display device.

摘要： Each of a plurality of remote control devices receives user-initiated video selections of any of direct broadcast satellite (DBS) channels, digital subscriber line (DSL) video content, and combinations of DBS channels and DSL video content. Based on the selections, each of a plurality of video processing modules is responsive to a corresponding one of the remote control devices to request any of a DBS channel, DSL video content, and a combination of a DBS channel and DSL video content, and to generate a television signal based thereon. A DBS distribution module simultaneously receives and distributes all DBS channels requested by the video processing modules. A DSL modem receives any DSL video content requested by the video processing modules. A networking module distributes the DSL video content to those of the video processing modules requesting same.
