PURPOSE: To enable simple and comprehensive operation control by providing an operation control means of an audio visual (AV) equipment which is selected through responding to demand signal from an input means of time that is input to a timer, a selection measures, a setting means, the timer and the like.

CONSTITUTION: A controller 1 of which main constituent is a microcomputer 3, controls operation of an AV equipment system 50 via a bus interface 10 and a bus line which is shown as a bold line, following operation signal which is input from a remote control unit 100 via a light receiving part 7, and process procedures stored in a ROM 5. An equipment system 50 has an AV selector 50A by which signal to be output from a TV tuner 50a and so on, is selected and switched and thereafter is input to a TV monitor 13. While, at the selector 50A, output signal of the tuner 50a and so on is made to be able to be input to a VTR-A and the like, at an audio amplifier selector 50B, output signal of an audio tuner 50f and so on is made to be able to be input to a compact cassette recorder 50g and the like, as well as is made to be able to be dubbed between the recorder 50g and a digital audio tape recorder 50h.
