ABSTRACT:
When a user commands a microprocessor, using a remote control, to output information about a video and audio signal output device itself to a monitor device, the microprocessor superimposes, on video signals decoded by a decoder, video signals of a terminal connection information image for displaying, on the monitor device, color images corresponding to output signals from respective output terminals of red (R), green (G) and blue (B) in a VGA terminal or a BNC terminal so as to form and output combined video signals to the monitor device. Thus, e.g. if the monitor device has multiple video signal input terminals for inputting output signals from the respective output terminals of R, G and B, and if no signal is input from one of the input terminals, the user can confirm the input terminal, from which no signal is input, by just watching the screen of the monitor device without confirming the actual connection of the input terminals.
