The present invention relates to a television with a built-in video accommodating device, and more particularly, to a television with a built-in video accommodating device in which a plurality of specific image signal sources and accompaniment signal sources having different recording methods and formats are freely available to a user. .

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 is provided for introducing a video and audio signal from an external device. Video and audio signals from video cameras, camcorders and video accompaniment devices can be monitored by CRT and speakers. 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 being developed and marketed is a device that displays lyrics along with song accompaniment by connecting to a TV monitor. It is largely 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 sound source, but since only 30 songs are contained on one laser disc, Juke Box is needed to service a large amount of songs. A disk changer such as

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 a decrease in the connection between the music and the music, since the number of songs contained in the compact disc is limited to about 15 songs, there is a disadvantage in that a disk changer is required as in a system using a laser displayer.

On the other hand, the computer accompaniment system cannot provide the same sound quality as the accompaniment system using a laser disc player and a compact disc graphic player, but it can provide a large amount of accompaniment information and lyrics information about 1,000 to 1500 songs. There is an advantage that the selection can be made faster, 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 generally connected to a 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 lyrics information of a specified song. To do that. At the same time, the controller 2 controls the text signal generator 4 to generate lyrics information of a specified song.

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 on its own, the user has to operate the television receiver separately in addition to the operation of the image accompaniment device, thereby causing inconvenience.

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

The image signal synthesizing unit is selected by the switch 604 by the selection control signal S1 among the output image signals of the LDP 601, the CDP 602, the VCR 603, or the signals of the graphic / text signal generator 242. The background image signal output to the cathode ray tube driver 30 is given to the cathode ray tube driver 30 in preference to an output television signal input to another input terminal by a blanking signal BLK generated in the image accompaniment mode. Output and display on CRT.

The accompaniment signal selected by the switch 607 by the selection control signal S2 is input to the adder 38, synthesized with the external microphone input signal, and then applied to the second selection unit 32. The second selector 32 selects the audio signal input from the adder 38 in the image accompaniment mode by the mode selection signal KA ₁ , and outputs the audio signal to the reverberation sound processor 34. After the reverberation sound processor 34 performs the reverberation sound processing and the equalizing process, the reverberation sound processing unit 34 outputs the amplification unit 36, and the microphone sound signal synthesized by the amplification unit 36 and the synthesized microphone audio signal are output through the speaker.

By such a control operation, if the user wants to output the background image and the accompaniment from a specific recording storage medium, the microcomputer 28, according to the key operation of the command input unit 42 and the remote controller (not shown), selects the control signal ( S1) and S2 are output to the switches 604 and 607, and a desired signal source can be selected and output from among a plurality of image signal sources and accompaniment signal sources having different formats according to the selection control signal. .

Specifically, when the user wants the background image and the accompaniment output from the LDP 601, the user operates the command input unit 42 and the keys of the remote controller (not shown). Accordingly, the selection control signals S1 and S2 are output from the microcomputer 28 to the switches 604 and 607, and the switch 604 selects and outputs the output signal of the LDP 601, and the switch. 607 also selects and outputs the output signal of the LDP 601.

If the user operates the command input unit 42 and the keys of the remote controller (not shown) to receive the background image from the VCR 603 and the accompaniment signal from the mini disk 605, then the microcomputer 28 The switch 604 selects and outputs a video reproduction signal of the VCR 603 according to the selection control signals S1 and S2 output from the switch, and the switch 607 selects and outputs an audio reproduction signal of the mini disc 605. do.

As described above, a plurality of image signal sources and accompaniment signal sources can be provided to freely output background images and accompaniment according to a user's selection, and background images and accompaniment signals recorded in various forms can be used.

As described above, according to the present invention, the image semi-permeable built-in television has an effect of maximizing satisfaction by allowing the user to be provided with various background images and accompaniment using the image semi-permeable-embedded television.
