The present invention relates to a method of detecting usage data of a television having a built-in video cycle period, and more particularly, to a usage data of a television having a built-in video cycle period, in which a user can detect cumulative data by using a confirmation key when the image accompaniment mode is used for a predetermined time. It relates to a detection method.

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 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 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. In addition to the deterioration of the connection between the image and the music, since the songs contained on the compact disc are 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, 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.

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. 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, the user has to operate a TV receiver separately in addition to the operation of the image accompaniment device.

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.
