Abstract
An identification terminal voltage detecting circuit detects a voltage of an identification terminal. A video switch is inserted into a signal line connecting a video circuit included in an internal circuit and the identification terminal. When a voltage representing that a video cable is connected to a connector is detected, and then a voltage representing that the video cable is terminated with specified impedance is detected, the control unit turns on the video switch.
