Abstract

PURPOSE:To improve the workability and the operability of a device, by constituting a device so that a first external video signal input terminal is separated automatically by connecting the output terminal of an external video signal to a second external video signal input terminal, and a second external video signal can be supplied to a cathode-ray tube. CONSTITUTION:By connecting the output terminal of an AV selector to a second input terminal 14, first input terminals 1a-1d are separated from a video signal processing circuit 9, and the second external video signal is supplied to the video signal processing circuit 9, and is displayed on the cathode-ray tube 10. Meanwhile, at this time, a resistor 21 is separated from a resistor 15 by opening between contacts 14a and 14b, then, a transistor 19 is energized. As a result, the collector potential of the transistor is set a low level, thereby, a microcomputer 23 detects the connection of the input to the second input terminal, and performs the same on-screen display as the above. Even when a signal to be switched to a changeover switch 2 is issued from a remote control transmitter, its output signal is not issued, and no switching of the change-over switch 2 occurs.
