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, 18 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 reproduced 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 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 the MIDI data outputs the accompaniment signal through the built-in sound source integrated circuit. The RGB video data of the background image with 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 to output an external video signal having lyrics superimposed as a video signal. Further, 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 detecting means 90 and the detected signal is CD-. The OK decoder 124 is received and score determination is performed, and the result is loaded on the video signal. The main controller 114 controls the whole of the system and controls the switching of the video selector 126 and the audio selector 130. 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, recognizes the remote control signal as a legitimate command signal to perform the corresponding command.

Effects of the compact disc player integrated television receiver configured as described above are as follows.

First, the set is maintained in the standby state by the primary power supply unit 78 of the power supply unit 40 in the state where commercial exchange is applied. That is, 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 through the remote controller, the television signal receiver 32 through the television power supply unit 80 supplies the television power to the video signal processor 36 and the audio signal processor 38. Voltage is provided. In the initial state, the selection means 44, 62, 72, 74 are switched to the TV mode. The selecting means 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 unit 34. The compact disc player unit 34 reads disc information from the read-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 means in accordance with the disc type. In the case of a CD digital audio disc, a 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 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, switch 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 to switch the third selection means 50 to the on state. Therefore, the TV screen can be selected as the background image at the time of song performance. In addition, in the case where it is desired to receive a background image from an external video source such as a video camera or a video cassette recorder, the switching control signal (X1) is connected 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 to switch the selection means 74 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. The first selecting means 44 allows the display to be displayed on the CRT 10. In addition, the compact disc player 34 may output a video signal, which is a composite video signal, but may output an RGB signal and display the RGB signal 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.
