Television Studio Video Switching Design for Control and Operating Simplification

The video system described simplifies the operational controls for studio program switching by indiscriminately accepting input signals which may or may not be synchronous with the local synchronizing pulses. Changes in signal system paths and video processing required by different forms of input signals are made automatically during a few picture lines, thus eliminating a manual control operation function and possible undesirable interruption of the video and synchronizing signals. Furthermore, the number of input circuits is reduced by means of flexible subswitching among a number of off-premise sources and all available inplant support facilities.
