The present invention relates to a television having a built-in video accommodating device. More particularly, the present invention relates to a video integrated circuit and a video accommodating disc recording medium by using an output signal of an image integrated circuit and a video accommodating disc recording medium. The present invention relates to a TV having a built-in video half-cycle, which is configured to use an output signal of a medium, so that the latest music can be additionally enjoyed by using an image integrated circuit and a video recording disc recording medium.

In general, a television can receive a video signal and an audio signal at the same time by receiving a radio signal transmitted from a broadcasting station, and an external signal input terminal for inputting a video and audio signal from an external device is installed. In addition, video and audio signals provided from a camcorder, video accompaniment apparatus, etc. can be monitored by a CRT and a speaker. Therefore, the user can select and watch the video and audio signals input through the television signal or the external signal input terminal using the operation button or the remote controller installed in the television.

On the other hand, the video accompaniment device that is rapidly developed and marketed is a device for displaying lyrics along with song accompaniment by connecting to a TV monitor, and an LD image accompaniment system using a laser disc player and a CDG image accompaniment using a cassette disc graphic player. It is divided into computer accompaniment system using system and memory.

By the way, LD video accompaniment system using laser disc player has the best video and sound quality than any other sound source. However, since only 30 songs are contained on one laser disc, it is possible to service juke box and juke box. Same exchanger is required.

In addition, the CDG image accompaniment system can provide the same sound quality as that of a laser disc, but only a limited number of still picture information recorded in a sub-code channel of a compact disc can be used. In addition to the deterioration of the connection between music and music, since the songs contained on the compact disc are limited to 15 songs, there is a disadvantage in that a disc changer is required as in a system using a laser disc player.

On the other hand, although the computer accompaniment system cannot provide excellent sound quality as in an accompaniment system using a laser disc player and a compact disc graphic player, it can provide a large amount of accompaniment information and lyrics information of about 1,000 to 1,500 songs. There is an advantage that the selection can be made at high speed, which will be described schematically with reference to FIG.

FIG. 1 is a schematic block diagram of a computer accompaniment apparatus using a memory, which provides a stereo accompaniment signal and lyrics information and is used in connection with a general monitor and an audio amplifier.

Referring to FIG. 1, when a specific song is selected by the command input unit 1 and an accompaniment start command is input, the control unit 2 controls the accompaniment signal generator 3 to generate an accompaniment signal of the specified song. To do that.

The voice signal input through the voice input unit 5 is synthesized with the accompaniment signal by the synthesizer 6 and then provided to the audio amplifier through the audio output terminal, and the output of the text signal generator 4 is provided to the monitor so that the user You can sing along with the accompaniment.

However, the computer accompaniment device requires a separate monitor and an amplifier in order to effectively monitor the accompaniment signal and the lyrics signal. In other words, the user had to purchase or handle two devices separately.

In addition, since the computer image accompaniment device is equipped with a command input unit in the control, the user has to operate a television receiver separately in addition to the operation of the image accompaniment device, which causes inconvenience in use.

In order to solve the above problems, Korean Patent Application No. 93-3422 by the present applicant discloses a system in which an image accommodating device and a television are integrated to enhance convenience of use. It will be described schematically with reference.

2 is a schematic block diagram of a TV with built-in video half-period, which performs both channel selection, video selection, adjustment of adjustment terminals including volume, and the like, in operation with an image-related system and an audio-related system. In the operation of performing the function of the image accommodating device, curve tack, pitch and speed adjustment, reservation setting, etc. are all performed.

In particular, in the video accompaniment mode, the audio signal is provided only by the video accommodating device, but the video signal is one of a broadcast signal of a selected channel formed by the television, an externally provided signal, and a graphic signal generated from the video accompaniment signal generator. By providing it, it is possible to provide a lively video corresponding to the contents of the song.

First, in operation of the video signal system, a broadcast signal (RF signal) input to the tuner 12 through the antenna 10 is converted into an intermediate frequency signal (IF signal) and input to the demodulator 14. The IF signal input to the demodulator 14 is formed of a composite video signal (CVS) and an audio signal (L / R) and input to the television signal selector 16. The television signal selector 16 also receives signals from the outside. That is, signals V1 and V2 at the first and second video signal sources (not shown) and signals S-V at the super VHS signal source (not shown) are input.

The video signal CVS, V1 or V2 selected by the television signal selection unit 16 is input to the luminance / color signal separation unit 18. The luminance signal Y + S including the synchronization signal separated by the luminance / color signal separator 18 is input to one side input of the first selector 20 and the color signal C is input to the color demodulator 22. On the other hand, as the other input of the first selector 20, the pseudo synchronization signal PS generated by the image accompaniment signal generator 24 is input. The signal Y + S or PS selected by the first selector 20 is input to the color demodulator 22.

On the other hand, when the super VHS signal S-V is selected by the television signal selector 16, it is directly input to the color demodulator 22 and the first selector 20 without going through the luminance / color signal separator 18.

The first selector 20 is controlled by the graphic mode signal G generated by the image accompaniment signal generator 24. When the graphic mode signal G is high, the image accompaniment signal generator 24, the pseudo synchronous signal PS is selected and output, and in the case of LOW, the video signal from the television signal selector 16 is selected and output.

The color signal C and the luminance signal Y + S inputted to the color demodulator 22 are demodulated into color difference signals R-Y, B-Y, G-Y, and -Y, and are input to the image signal synthesizing unit 26. The synchronization signal H / V extracted from the luminance signal Y + S including the composite synchronization signal is provided to the image accompaniment signal generator 24 and the controller 28. The OSD (On Screen Display) signal applied to the color demodulator 22 by the controller 28 is combined with the demodulated color difference signal and output.

It is synthesized and output to the CRT driver 30. Here, the OSD of the control unit 28 is applied to the image signal synthesizing unit 26 by applying the blanking signal BLK-OSD of the control unit 28 and the blanking signal BLK of the image accompaniment signal generator 24. The priority is set in the order of the signal, the graphic signal from the video accompaniment signal generator 24, the text signal, and the signal from the television signal selector 16.

Next, in the operation of the audio signal system, the audio signal V1, V2 or S-V selected by the television signal selection unit 16 is input to the second selection unit 32. When the television mode is selected by the controller 28, the audio signal from the television signal selector 16 is selected by the second selector 32. When the image accompaniment mode is selected, the video accompaniment signal generator 24 The accompaniment signal is selected and output to the audio output device. That is, the signal output from the second selector 32 is input to the reverberation sound processor 34, and after the reverberation sound processing and the equalizing process are performed, it is output to the amplifier 36. The signal amplified by the amplifier 36 is provided as a voice output by the speakers L, R, and WOOFER.

The voice signal VOICE introduced through the microphone is provided by the voice synthesizer 38 as an accompaniment signal of the image accompaniment signal generator 32.

As shown in FIG. 2, the image accompaniment signal generator 24 includes a graphic / text signal generator 242 for generating graphic signals and text signals, an accompaniment signal generator 244 for generating accompaniment sounds, and graphics / characters.

Meanwhile, in FIG. 2, the audio signal input through the microphone MIC is processed by the external microphone signal processor 50 and synthesized with the accompaniment signal by the voice synthesizer 38. The computer 28 converts the OSD signal to an image signal synthesizing section 26 and synthesizes the video signal. A detailed block diagram of this is shown in FIG.

As shown in FIG. 3, the audio signal input through the microphone MIC has to be amplified because its signal level is weak. Therefore, the preamplifier 501 amplifies to a level usable by the component in the rear stage, and the amplified signal is input to the level amplifier 502 to correct the level. The correction made at this time is to adjust the frequency characteristic and gain gain of the signal and to adjust the output. After the correction operation is performed, the voice signal is input to the voice synthesizer 38 and to the display data processor 241. In this case, the A / D converter 243 in the display data processing unit 241 is inherent in the image accompaniment signal synthesizing unit 24, and the microprocessor 245 and the OSD unit 247 are inherent in the microcomputer 28. will be.
