4 is a circuit block diagram of a preferred embodiment of the compact disc player section 34. As shown in FIG. 102 is a compact disc, 104 is an optical pickup, 106 is a spindle motor, 108 is a high frequency signal amplifier, 110 is a servo circuit, 112 is a digital signal processor, 114 is a main controller, 116 is a sub-controller, 118 is a disc tray driving circuit, 120 A CDG decoder, 122 a CD-ROM decoder, 124 a CD-OK decoder, 126 a video selector, 128 a digital analog converter, and 130 an audio selector. The signal reproduced from the disc is output from the digital signal processor 112 to the CD.

Here, if the disc is a CDG disc, the sub code is transmitted to the CDG decoder 120 so that the NTSC encoded graphic signal is reproduced and output. At this time, the CD signal is reproduced and output through the digital analog converter 128.

In the case of a CD-OK disc, the video selector selects a video signal to be re-audioed by the CD-OK decoder 124, and otherwise selects an output of the CDG. The audio selector 130 selects an accompaniment signal output from the CD-OK decoder 124 in the case of a CD-OK disc and otherwise selects an audio signal output from the digital analog converter 128.

The CD-OK decoder 124 receives data obtained from the CD-ROM decoder 122, and outputs the MIDI data as an accompaniment signal through an internal magneto integrated sound integrated circuit. The RGB video data of the background image having the lyrics data superimposed is an RGB signal. It can be output as a video signal through a built-in NTST encoder.

In addition, the CD-OK decoder 124 may input an external video signal and output a back video signal in which lyrics are superimposed as a video signal. In addition, as shown in FIG. 3, the signal input through the microphone 15 is amplified by the amplifier 88 and the amplified signal is detected by the microphone input detection unit 90 and the detected signal is CD-OK. The decoder 124 receives the score, performs a score determination, and loads the result on a video signal.

The sub-controller 116 exchanges the first control signal C1 in the form of data with the television control unit 42 via the data line and also receives the second control signal C2 received from the remote control signal receiver 86. . The sub-control unit 116 compares the first and second control signals (C1, C2) and if the two signals match, and recognizes the remote control signal as a legitimate command signal to perform the corresponding command.

The operation of the apparatus shown in FIGS. 3 and 4 is as follows.

First, in the state where the use alternating current is applied, the set is maintained in the standby state by the primary power supply unit 78 of the power supply unit 40. That is, the standby power is supplied to the microprocessor 84 of the television control unit 42 to maintain the reception standby state of the remote control signal.

When the user presses the power button 24 or inputs a power-on command via the remote control, the television power source 80 supplies the television signal to the television signal receiver 32, the video signal processor 36, and the audio signal processor 38. The voltage is high. In the initial state, the selectors 44, 62, 72 and 74 are switched to the TV mode. The selector 50 is kept off. Therefore, the television mode is always set as the initial mode.

If the user presses the CD power key of the control box or inputs the CD power key through the remote controller, the microprocessor 84 generates a power control signal PW to enable the CD power supply 82, and thus the CD power supply 82 ) Supplies a power supply voltage to the compact disc player 34.

The compact disc player 34 reads disc information from the lead-in area of the disc inserted through the door, and transmits a control signal corresponding to the disc to the television control unit 42.

The television control unit 42 controls the switching of the selection units 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 selector 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, the switching control signals X2 and X6 are generated to switch the selectors 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 number control signal X3 is switched to the on-state state of the third audio selection unit 50. 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, the switching video suppressor signal (X1) is connected by connecting the video output terminal of the device to the wall terminal and selecting the corresponding external video input terminal. Is generated so that the selector 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. Displayed on the CRT 10 through the first selector 44.

In addition, the compact disc player unit 34 may output a video signal as a composite video signal, but may output an RGB signal and display the same on the CRT 10 through the RGB mixer 58 of 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.
