A home videoconferencing system 100 uses a standard television receiver 16 and a camcorder 14. The video controller 112 converts an outgoing analog video signal into a compressed digital video signal; an audio controller 116 converts an outgoing analog audio signal into a compressed digital audio signal. The system controller 120 multiplexes, synchronizes and error corrects outgoing and incoming digital system signals. The digital system signals are coupled to a modem 122 for transmission and reception over analog phone lines 124.
