Abstract: A computer system and method for providing digital video and data 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. A user requests a particular program and, if authorized, receives at least that program over the communication channel. Simultaneous with the digital video content supplied on the channel is both bi-directional data service (such as for example, Internet data) and POTS (plain old telephone service). In this manner, a communication channel that is presently available to a large percentage of the population may be used to deliver digital video content, bi-directional data and POTS simultaneously.

Abstract: A novel system and method for maintaining timing synchronization in a digital video network, in conjunction with a 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.
