Abstract
A system for selectively interconnecting a plurality of audio/video sources and a plurality of audio/video communication devices including a single switch, a mixer to combine the audio and video signals as a single signal from a source to the switch and a modulator for modulating the video signal after the switch for optical transmission to the communication devices. The modulated audio and video signals directly drive an optical transmitter as a composite signal. A programmable interface is provided at the sources and at the communication devices for translating system remote control signals to source and communication device control signals for the connected device. The interface provides ALL CALL overrides.
