  • Publication number: 20150003535
    Abstract: A system or method for processing a variable bit rate representation of an image sequence can include segmenting a variable bit rate representation of an image sequence into a plurality of segments and creating a second representation of the image sequence where a block of information from a first segment of the plurality of segments is interlaced with blocks of information of a second segment of the plurality of segments. The second representation of the image sequence can include a fragment header indicating the block of information of the first segment of the plurality of segments interlaced with the blocks of information of the second segment of the plurality of segments.

  • Patent number: 8904468
    Abstract: A set-top box (STB) of a television system receives web-based content, such as a web page, from a wide area network such as the Internet. The web-based content is provided to the STB for display. In response to an instruction, the STB provides all or a portion of the web-based content to a printer for printing. The printer can be connected to the STB via a network or through a computer connected to the STB on the same network. By providing an option to print the web-based content, the usefulness of the content is enhanced.

  • Publication number: 20140269931
    Abstract: A method comprises determining a plurality of time intervals Tp and Tn within a variable bit rate (VBR) representation of an image sequence. The time intervals Tp are those in which a number of blocks of information per unit time is greater than a baseline value. The time intervals Tn are those in which a number of blocks of information per unit time is less than the baseline value. A second representation of the image sequence is created in which some blocks of information Bp are removed from the time intervals Tp and interlaced with blocks of information Bn in the time intervals Tn to reduce a variation in a number of blocks of information per unit time between the time intervals Tp and Tn.

  • Patent number: 8776153
    Abstract: 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.

  • Patent number: 7849384
    Abstract: 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.
