Multi-component video system controller

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