ABSTRACT:
The present invention provides a distribution system for audio and video services from a centralized source using lightwave signals generated from terminal equipment through an optical carrier to multiple locations in a facility. The terminal equipment reversibly convert audio, video, and control signals from electrical into lightwave signals. The terminal equipment also provide for electrical output at the remote locations with the appropriate format for various audio and video speakers and displays. A controller selects and converts audio communication signal into a standard audio format and directs the signal to the desired remote location in response to the control signal.
