The present invention relates to a method of performing a display function of a built-in video accommodating television, and more particularly, by adding lyrics selection and deletion functions to a video accompaniment function of a built-in video accommodating television. How to perform the lyrics selection and deletion function of the built-in video repeater built-in TV that allows the user to arbitrarily block or select the text signal outputted from the 9th and to replace the lyrics information with a bar when the text signal is blocked. It is about.

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 view the video and audio signals input through the television signal or the external signal input terminal using the remote control, which is an operation button installed in the television.

On the other hand, the video accompaniment device currently being developed and marketed is a device that displays lyrics along with song accompaniment by connecting to a TV monitor, LD video accompaniment system using a laser disc player, and CDG image accompaniment system using a cassette disc graphic player. And a computer accompaniment system using a memory.

By the way, LD video accompaniment system using laser disc player has the best image 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 video accompaniment system can provide the same sound quality as a laser disc, but provides only a limited number of still picture information recorded in a sub-code channel of a compact disc, compared to a laser disc. Not only is the connection between video and music deteriorating, but also the connection between video and music is reduced compared to compact discs, and since the number of songs contained on the compact disc is limited to about 15 songs, a disc changer as in a system using a laser disc player There was a downside required.

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 can provide a large amount of lyrics information such as 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 device 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. 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 by 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.
