<p>An apparatus and method for transporting infrared and radio frequency signals operates in conjunction with a digital video and data delivery system to allow the transport of infrared signals and radio frequency signals along with the delivery of digital video content, bi-directional data services such as Internet data, and old telephone service (POTS) to an end user over a communications channel (16). 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 communications channel (16). Simultaneous with the digital video content supplied on the channel is both bi-directional data service and POTS. In this manner, a communications 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. In addition, the digital video and data delivery system employs novel architecture to synchronize the timing of the digital video signal to ensure that the digital video program received by the user is of high quality and complies with the present state of the art MPEG-2 video standard.</p> |
