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 a video signal and an audio signal input through a television signal or an external signal input terminal using an operation button or a remote controller installed in the television.

On the other hand, the video accompaniment device that is rapidly 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 CD 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 can be used to service a large amount of songs. A disk changer such as

In addition, the CD accompaniment system can provide the same sound quality as that of a laser disc, but provides only a limited number of still picture information recorded in a sub-code channel of a compact disc. In addition to the deterioration of the connection between the music and the music, it is stored on a compact disc, and since the number of songs is limited to about 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, computer accompaniment system cannot provide the same sound quality as accompaniment system using laser disc and compact disc graphic player, but it can provide a large amount of accompaniment information and lyrics information about 1,000 ~ 1,500 songs, and selection of songs. There is an advantage that can be made at a 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.
