System for integrated distribution of switched voice and television on coaxial cable and with video signal transmission originating from subscriber locations

摘要

A system for voice and video distribution amongst a plurality of telephone subscriber locations operating on a broadband cable network. The subscriber locations are adapted to establish RF transmitting and receiving channels for carrying voice and signalling information and each further includes a tunable video signal generator and a tunable video signal receiver for coupling video signals to and from subscriber location video RF broadband channels of the cable network. A central switch is also coupled to the cable network and enables each RF transmitting channel to be selectively coupled to any of the RF receiving channels and also enables a particular subscriber location video RF broadband channel to be assigned to a subscriber location.
