  • Patent number: 6154772
    Abstract: A novel digital video and data delivery system makes possible the delivery of digital video content, bi-directional data services such as Internet data, and plain old telephone service (POTS) to an end user over a communications channel. The channel is typically the copper wire pair that extends between a telephone company central office and a residential premises, but may be any communication medium that supports the communication of compressed digital video, bi-directional data, such as Internet data, and POTS, and indeed, may be a wireless connection. The digital video and data delivery system capitalizes on a bus, or broadcast backplane, created by circuitry contained within the central office. The broadcast backplane enables a plurality of video program data to be available to each end user, and allows a plurality of end users access to a plurality of video programming content without the necessity of delivering the entire program content to each end user.
