BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording control method of a TV having a built-in image half-period, and more particularly, to a background screen generated from a TV having a built-in image half-period and a subject photographed through an external camcorder as a picture in a picture or either The present invention relates to a recording control method of a built-in video half-period television which can record on a recording medium by using a camcorder by selectively displaying and selectively applying a background screen or a subject to a camcorder.

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 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 compact 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 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 the number of songs contained in the compact disc is limited to about 15 songs. Therefore, there is a disadvantage in that a disc changer is required as in a system using a laser disc player.

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 used in connection with a general monitor and an audio amplifier.
