The television control unit 42 controls the switching of the selection means in accordance with the disc type.

In the case of a CD digital audio disc, the switching control signal X6 is generated to switch the second selection means 62 to the CD mode and display related information, for example, disc table contents information in the OSD. Thus, the user can interactively use the set through the remote control while viewing the OSD displayed on the CRT. In the case of a CDG or CD-OK disc, switching control signals X2 and X6 are generated to switch the selection means 44 and 62 to the CD mode. When using the song playing function using a CD-OK disc, a background image is provided as a still image recorded on the disc. When the user presses the background selection key of the control box 26, the switching control signal X3 is generated, and the third selection means 50 is switched on. Therefore, the TV screen can be selected as the background image at the time of song performance. In addition, when the user wants to receive a background image from an external video source such as a video camera or a video cassette recorder, a switching control signal (X1) is obtained by connecting the video output terminal of the corresponding device to the external video input terminal and selecting the corresponding external video input terminal. Is generated so that the selection means 74 switches to select the corresponding external video signal. In the case of using the external video as a background screen, the compact disc player unit 34 inputs an external video signal to the input terminal EX to superimpose the lyrics information generated internally, and to output the video signal having the lyrics information superimposed. Display on the CRT 10 via the first selection means 44. In addition, the compact disc player 34 may output a video signal as a composite video signal, but may output an RGB signal and display the 58 on the CRT 10 through the video processor 46. If the CD mode is not selected in order to minimize power consumption, the CD power supply unit 82 is in a disabled state to cut off the power supply to the compact disc player unit 34.
