The present invention relates to a music selection method of a multi-mode TV with a built-in video half-cycle. More specifically, the broadcasting system (NTSC, PAL) can be used in other regions without additional circuit configuration, and user's preference. The present invention relates to a method of selecting a song of a multi-type television having a built-in image half-cycle that can automatically select stored sound source data according to the type.

In general, a television is provided with an external signal input terminal for receiving a radio signal transmitted from a broadcasting station and introducing a video and audio signal. The television is used to display video and audio signals provided from a video cassette recorder, camcorder, video accompaniment device, and the like. Can be monitored by the speaker. 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. 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 that of an 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 so that the user You can sing along with the accompaniment.

However, the computer accompaniment apparatus 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.

Disclosure of Invention The present invention provides a song selection method for a multi-broadcast TV having a built-in video half cycle in which a user can arbitrarily select sound source data that can be shared by the world.

In order to achieve the above object, a feature of the song selection method of a multi-mode TV having a built-in image accompaniment according to the present invention is a microprocessor for generating an image accompaniment unit, a television unit, and a control signal for selecting the image accompaniment unit and a television signal. A method for selecting a song of a multi-mode television having a video half-cycle for generating an image signal according to an input television broadcasting system, the method comprising: detecting whether an auxiliary memory operation key is input in a video half-cycle mode; Detecting input of a corresponding key for each year; The year consists in selecting the desired data from the song data displayed by the input of the corresponding key.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a multi-mode TV with a built-in video half-cycle according to the present invention will be described in detail.

3 is a schematic block diagram of a multi-mode television with a built-in image semi-period according to the present invention.

Referring to FIG. 3, a broadcast signal R.F. input to the tutor 32 through an antenna is converted into an intermediate frequency I.F. signal and input to the multi-IF processing unit 33. The IF signal input to the multi-IF processing unit 33 is divided into a composite video signal and an audio signal and input to the switching circuits 36 and 37, respectively. The television signal switching circuits 36 and 37 are input with external signals, i.e., the first and second video signals V1 and V2 and the signal S-V from a straight signal source (not shown). The composite video signal that has passed through the multi-IF processing unit 33 is divided into a luminance signal (Y + S) and a color signal (C) including a synchronization signal in a luminance / color signal separation unit (not shown), respectively. ), The luminance signal (Y + S) is also input to the synchronization signal separation unit, and only the synchronization signal is separated, and then to the broadcasting system determination unit (45).

The broadcast discrimination unit determines a broadcast method by determining how many scan line pulses exist during one frame.

Here, it can be seen that the number of scan line pulses is NTSC and 625/2 is PAL. After recognizing the broadcast method, the microprocessor controls the sync signal generator 49 to generate a Composite Synchro Nizing Signal suitable for the identified sync method, and on the other hand, the image generator 50. By generating a graphic screen with a vertical resolution of 525 lines (NTSC), 625 lines (PAL) for the synchronization method. The composite synchronous signal and the graphic signal generated in this way are input to the multi video color signal processor 34, and are processed to the image signal synthesizer 51 after the color signal processing is performed by the control signal C3 of the microprocessor.

The video signal synthesizing unit 51 inputs signals of the graphics / character processing unit 43 on the image half-period board (karaoke board) and the OSD circuit (not shown) in the microcomputer 40, and then broadcast signals or graphics. It is synthesized with the character processing unit signal and then input to the CRT driving unit 52. The CRT driver 52 displays a screen on the CRT.

On the other hand, a music selection method in the case where a cartridge, which is a nonvolatile memory that stores voice information as an auxiliary memory, is electrically connected according to a user's selection, will be described below with reference to FIG.

First, the microprocessor in the microcomputer 40 checks the operation signal input from the command input unit 31a or the remote controller 31a. In this case, the program may be embedded so that the user can determine whether the image is in the half-cycle mode according to the number of times the user presses the keypad (not shown) mounted on the television receiver or the set-on key mounted on the remote controller. It may be configured.

Once it is determined that the image is in the half-cycle mode, the microcomputer 40 detects whether an auxiliary memory operation key has been input (S403). If the auxiliary memory operation key is not input, the general image half-cycle mode is performed (S408). On the contrary, when it is confirmed that the auxiliary memory key operation key is input, the microcomputer checks the key input for each year.

That is, according to the present invention, the sound source data memory is already configured to store memories of pop songs for each year and to display data for each year on the screen. If you want to listen to the 1960's song on the program, press the corresponding numeric key, the microcomputer 40 recognizes it, finds the corresponding memory address, accepts the data in the address, and synthesizes the video signal through the image accommodating processor 42. Control to provide to the unit 51 (S404). Preferably, for example, in 1960, when 6 is pressed, the 1960s song may be displayed.

After the song display mode (S405) of the corresponding year is performed, the microcomputer again checks whether there is a song selection key input (S406), which is performed by the user to move the cursor pointing to the data displayed on the screen. It is the process of checking whether there is a key input pressed by the user.

If the song selection key is not input, the process returns to step 405, and if the selection key is input, the corresponding mode for the selected song is performed (S407).

As described above, according to the song selection method of the multi-method television with the built-in video half-cycle according to the present invention, it is possible to perform the video half-cycle and the TV mode in all regions regardless of the broadcast system, The built-in old pop song is built into the auxiliary memory, allowing you to select a song that suits your preferences.
