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 reproduced by the CD-OK decoder 124, and selects an output of the CDG. The audio selector 130 selects the accompaniment signal output from the CD-OK decoder 124 in the case of a CD-OK disc and otherwise selects the 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 the built-in sound source integrated circuit. The video signal is output through the 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. 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 detecting means 90 and the detected signal is CD-.

FIG. 5 is a diagram for explaining the power cutoff of the television receiver with a compact disc player integrated television according to the present invention, and when the power key is pressed to cut the power while the door of the compact disc player with a television receiver is opened, FIG. The power cutoff signal is input to the microprocessor 84 of the television control unit 42. When the power cut-off signal is input to the microprocessor 84, the control signal SC for cutting off the power of the video signal processor 36 is output to the video signal processor power supply 81 to turn off the video signal processor 36. Turn off the television screen (CRT) 10. Therefore, the user recognizes that the power cutoff signal has been input. On the other hand, when a signal indicating that the door is completely closed from the compact disc player 34 is input to the microprocessor 84, the microprocessor 84 sends a control signal MC for turning off the compact disc player 34 to the main power supply unit. Output to (83).

Another method of turning off the power of the compact disc integrated television receiver outputs a control signal for adjusting the contrast of the television screen (CRT) 10 to the television signal processor 36 when the power-off signal is input to the microprocessor 84. As a result, the contrast of the television screen (CRT) 10 is changed and the user recognizes that the power cutoff signal has been input. If a signal indicating that the door is completely closed from the compact disc player 34 after changing the contrast of the television screen (CRT) 10 is input to the microprocessor 84, the microprocessor 84 causes the compact disc player 34 ) Is output to the main power source 83 for turning off the control signal MC.

At this time, the main power supply unit 83 outputs the standby signal Vstc to the microprocessor 84 to bring the television into a standby-by state. In addition, when the power is applied again, the microprocessor 84 stores data that is being performed when the power off signal is input to maintain the state before the power is turned off.

The effects of the present invention configured as described above are as follows.

First, in the state in which commercial exchange 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, 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 control, the TV power supply voltage is supplied to the television signal receiver 32, the video signal processor 36, and the audio signal processor 38 through the television power supply 80. This is provided. In the initial state, the selection means 44, 52, 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. When 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 the power control signal PW to enable the CD power supply 82, and thus the CD power supply 82 Supplies power 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 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 displays with the OSD shown on the CRT. 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 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, 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 unit 34 may output a video signal, which is a composite video signal, and output the RGB signal to display 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.

As described above, the compact disc player integrated television receiver integrates the TV set and the CD song accompaniment set into one set, which can improve the convenience of use and can easily provide a variety of background images in the song accompaniment function. You can save resources by unifying some of the

In addition, if the power cutoff key is input while the door of the compact disc player integrated television receiver is open, the TV screen notifies that the power cutoff signal has been input and cuts off the power after the door is completely closed. It can be recognized.
