  • Publication number: 20040006769
    Abstract: 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.

  • Publication number: 20040005039
    Abstract: A digital subscriber line access network comprises a remote Ethernet device disposed in a serving area interface. The remote Ethernet device serves as an Ethernet bridge for a neighborhood service area. The remote Ethernet device communicates with a plurality of customer premises modems in the neighborhood service area using an Internet Protocol over an Ethernet standard with a digital subscriber line physical layer. An Ethernet switch disposed at a central office communicates with the remote Ethernet device via a fiber optic medium using an Internet Protocol over a second Ethernet standard. The Ethernet switch provides a packet data core network termination.

  • Publication number: 20040006772
    Abstract: Each of a plurality of remote control devices is to receive a user-initiated video selection of any of a plurality of channels. Each of a plurality of video processing modules is responsive to a corresponding one of the remote control devices to request a channel based on the user-initiated video selection. A distribution module simultaneously receives all channels requested by the video processing modules and distributes the channels to those of the video processing modules requesting same. Each of a plurality of modulators is to generate a television signal based on the channel requested by an associated video processing module. A network interface is in communication with a modem to provide a data networking signal. Each of a plurality of combiners combines the television signal from a modulator with the data networking signal to form a corresponding combined television and data networking signal.

  • Publication number: 20030182237
    Abstract: A storage medium having stored thereon content for a plurality of different versions of a motion picture is provided at a retail store. After a customer has selected the storage medium at the retail store, data is stored to the storage medium at the retail store to select one of the different versions of the motion picture for playback by the customer. A transaction is performed which permits the storage medium to be removed from the retail store for playback of the version of the motion picture by the customer.

  • Publication number: 20030118098
    Abstract: A single compression engine determines a plurality of discrete cosine transform (DCT) coefficients based on a discrete cosine transform of a plurality of blocks of data. The single compression engine provides first and second DCT-encoded signals. The first DCT-encoded signal uses at most t coefficient bits to represent each of the DCT coefficients. The second DCT-encoded signal uses at most u coefficient bits, where u is less than t, to represent each of the DCT coefficients.

  • Publication number: 20030056223
    Abstract: Society of Motion Picture and Television Engineers (SMPTE) video data is separated into first data and second data. A first signal is formed based on the first data. A second signal is formed based on the second data. The first signal is transported via a first Optical Carrier 3 (OC-3) channel. The second signal is transported via a second OC-3 channel.

  • Publication number: 20030043915
    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.

  • Publication number: 20020170063
    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.
