Abstract
A network interface module operably connected to a subscriber's television receiver and to a switched broadband digital network includes a fiber-compatible digital transceiver. A downlink receiver in the transceiver detects video/audio/data information that is time-multiplexed within a serially transmitted digital signal optically transmitted by the switched digital network as a broadband digital downlink channel. The detected information is decoded into a parallel format of video/data samples, audio samples, and recovered sample clock that are applied to a digital switch in the television receiver.
