Abstract

PURPOSE:To improve the convenience of a user by executing a prescribed display by a display device at the time of having no video signal in a video mode in which a switch circuit is connected to an external input video signal side. CONSTITUTION:The switch circuit 5 selectively selects the video signal and the external input video signal from a tuner 2. A synchronizing signal is detected by a detecting means 6 disposed in the output side of the switch circuit 5. When the video mode is selected and the video signal is not present, the synchronizing signal is not detected by the detecting means 6. When the synchronizing signal is not detected by the detecting means 6, the prescribed display is executed on the display device 12.
