Abstract
A circuit for coupling the demodulated composite video signal to a Video Tape Recorder and for selectively coupling either that signal or a signal from an alternate source to the receivers video processing circuitry. The circuit includes diodes having inputs separately connected to the set of video signal sources and outputs coupled in common to a control circuit that determines which signal is coupled to the output and which is isolated from it.
