PROBLEM TO BE SOLVED: To miniaturize components by sharing an external input terminal and an external output terminal and to individually switch the video/audio signals of the external terminals corresponding to the needs of a user. SOLUTION: In an external input/output circuit, an input signal processing circuit 3 is switched by an input/output signal changeover switch 4 so that an external video input/output sharing terminal 1 and an external audio input/ output sharing terminal 2 can be switched to the input terminal and the output terminal corresponding to the needs of the user. Thus, components can be miniaturized and the video/audio signals of the external terminals can be individually switched as needed. |
