Abstract : The patent describes a composite display system for a plurality of television cameras in which one camera develops synchronizing signals and video waveform switching signals for the other cameras using delays from one-shot multivibrator circuits. The video switching is performed by a circuit having dual gate insulated field effect transistors with one gate of each being fed by a switching waveform signal and the other gate by the video signal from the corresponding camera.
