ABSTRACT:
Apparatus for simultaneously controlling the operating modes of a plurality of coupled video signal processing devices is disclosed. Manually operated pushbutton selectors provide D.C. control voltages to a plurality of electronic RF switches to permit the simultaneous viewing and recording of signals from various sources such as cable TV (CATV), subscription TV decoder (STV), video record (or disc) player, etc., in any desired combination. Video signal losses due to signal splitting are avoided when viewing and recording the same input signal by means of unique cooperation between view and record manually operable selectors. Electronic diode switching circuitry controlled by a minimum number of user selectable inputs allows for a reduced number of controller components and simplified design while facilitating user operation.
