The present invention relates to a television with a built-in video half-cycle, and more particularly, to display OSD text when the position of the lyrics pre-stored in graphics and the text signal output from the on-screen display (OSD) circuit is increased in the video half-cycle mode. The present invention relates to a method of moving a character position of a video semi-permeable television with a position shift. In general, a TV is provided with an external signal input terminal for receiving a radio signal transmitted from a broadcasting station to introduce a video signal and an audio signal, and through this, a CRT tube is provided for video and audio signals provided from a video cassette recorder, a camcorder, a video accompaniment device, and the like. Can be monitored by the and and 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 for displaying lyrics along with song accompaniment by connecting to a TV monitor, and 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. 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, computer accompaniment system cannot provide the same sound quality as accompaniment system using laser disc player 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 select the song. 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 device using a memory, which provides a stereo accompaniment signal and lyrics information and is connected to 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. 2 is a schematic block diagram of a TV with built-in video half-period, which is classified into a video-related system and a voice-related system. Also, in the operation of performing the functions of a television, adjustment terminals including channel selection, video selection, and volume are included. In the operation to perform the function of the image accompaniment device, the curve tack, the pitch and speed adjustment, reservation setting, etc. are all performed. In particular, in the video accompaniment mode, the audio signal is provided only by the video accommodating device, but the video signal is one of a broadcast signal of a selected channel formed by the television, an externally provided signal, and a graphic signal generated from the video accompaniment signal generator. By providing it, it is possible to provide a lively image corresponding to the contents of the song. First, in operation of the video signal system, a broadcast signal (RF signal) input to the tuner 12 through the antenna 10 is converted into an intermediate frequency signal (IF signal) and input to the demodulator 14. The IF signal input to the demodulator 14 is formed of a composite video signal (CVS) and an audio signal (L / R) and input to the television signal selector 16. The television signal selector 16 also receives signals from the outside. That is, signals V1 and V2 at the first and second video signal sources (not shown) and signals S-V at the super VHS signal source (not shown) are input. The video signal CVS, V1 or V2 selected by the television signal selection unit 16 is input to the luminance / color signal separation unit 18. The luminance signal Y + S including the synchronization signal separated by the luminance / color signal separator 18 is input to one side input of the first selector 20 and the color signal C is input to the color demodulator 22. On the other hand, as the other input of the first selector 20, the pseudo sync signal PS generated by the image accompaniment signal generator 24 is input. The signal Y + S or PS selected by the first selector 20 is input to the color demodulator 22. On the other hand, when the super VHS signal S-V is selected by the television signal selector 16, it is directly input to the color demodulator 22 and the first selector 20 without passing through the luminance / color signal separator 18. The first selector 20 is controlled by the graphic mode signal G generated by the image accompaniment signal generator 24. When the graphic mode signal G is high, the image accompaniment signal generator 24, the pseudo synchronous signal PS is selected and output, and in the case of LOW, the video signal from the television signal selector 16 is selected and output. The color signal C and the luminance signal Y + S inputted to the color demodulator 22 are demodulated into color difference signals R-Y, B-Y, G-Y, and -Y, and are input to the image signal synthesizing unit 26. The synchronization signal H / V extracted from the luminance signal Y + S including the composite synchronization signal is provided to the image accompaniment signal generator 24 and the controller 28. The OSD (On Screen Display) signal applied to the color demodulator 2 by the controller 28 is combined with the demodulated color difference signal and output. As another input of the image synthesizing unit 26, graphic signals and text signals from the image accompaniment signal generating unit 24 are input in the form of R, G, B, BLK, and synthesized with the color difference signals provided from the color demodulation unit 22. And output to the cathode ray tube (CRT) driver 30. Here, by applying the blanking signal BLK_OSD of the control unit 28 and the blanking signal BLK of the image accompaniment signal generator 24 to the image signal synthesizing unit 26, the OSD signal of the control unit 28, The order of priority is set in the order of the graphic signal and the text signal in the video accompaniment signal generator 24 and the signal in the television signal selector 16. Next, in the operation of the audio signal system, the audio signal SVCS, V1, V2, or S-V selected by the television signal selector 16 is input to the second selector 32. When the television mode is selected by the controller 28, the audio signal from the television signal selector 16 is selected by the second selector 32. When the video accompaniment mode is selected, the video accompaniment signal generator 24 The accompaniment signal is selected and output to the audio output device. That is, the signal output from the second selector 32 is input to the reverberation sound processing unit 34, and after the reverberation sound processing and equalizing processing are performed, it is output to the amplifier 36. The signal amplified by the amplifier 36 is provided as a voice output by the speakers L, R, and WOOPER. The voice signal VOICE introduced through the microphone is combined with the accompaniment signal of the image accompaniment signal generator 24 by the voice synthesizer 38 and then provided to the second selector 32. On the other hand, as shown in FIG. 2, the image accompaniment signal generator 24 includes a graphic / text signal generator 242, an accompaniment signal generator 244, an image accompaniment controller 246, and an external interface (not shown). It includes. The graphic / text signal generator 242 generates a graphic signal and a text signal. The accompaniment signal generator 244 generates accompaniment sounds. The image accompaniment controller 246 controls the operation of the graphic / text signal generator 242 and the accompaniment signal generator 244 and generates a pseudo synchronous signal. The graphic / text signal generator 242 inputs graphic / text information and sound source information that may be provided from the outside to the graphic / text signal generator 242 and the accompaniment signal generator 244 through an external interface (not shown). to provide. The graphic / character signal generator 242 includes a graphic memory for storing graphic information, a character memory for storing character information, a graphic / character processor for combining graphic information read from the graphic memory and character information read from the character memory, and the graphic. And a D / A converter for digitally / analog converting the output of the character processor.

The accompaniment signal generator 244 digitally / analogs an output signal of a sound source information processor and a sound source information processor that inputs sound source information stored in the sound source memory, sound source memory read from the sound source memory, and converts and outputs the accompaniment signals. A D / A converter is provided. Here, the sound source information stored in the sound source memory is MIDI information. On the other hand, the image accompaniment controller 246 performs a built-in program to control the graphic / text signal generator 242 and the accompaniment signal generator 244, a remote control command from a remote control device (not shown) And a synchronization signal generator for generating a pseudo-synchronous signal equivalent to the synchronization signal of the television signal and the interface transmitted to the microprocessor. On the other hand, the preamplifier 40 interfaces a control command from the remote control to the microcomputer 28, and the command input section 42 provides at least a television / image accompaniment mode selection key for inputting a command signal to the microcomputer 28; Accompanied video signal selection keys, curved digit number pads, start / cancel keys, reservation keys, pitch adjustment keys, and speed adjustment keys are provided. Thus, since the video accompaniment is formed integrally with the television, it is possible to increase convenience in use. Accordingly, the present invention is an advance of the above description, and an object of the present invention is to adjust the position of the characters in the OSD circuit when the position of the lyrics pre-stored in the graphic and the characters generated in the OSD circuit overlap in the image half-cycle mode. It is to provide a video semi-permeable built-in television. According to the present invention, a character position shifting method of an image semi-permeable television according to the present invention has an on-screen display circuit inside or outside, outputs a switching operation control circuit in the system, and has a micro position shifting means for shifting a text signal. A method of moving a character position of a television having a built-in image repeating period comprising a computer, the method comprising: determining a character position displayed according to the mode when one of the image repeating mode and the television mode is selected by key input; When the on-screen display key is input, when the input character and the currently displayed character overlap, the position shift key moves the character position moving step up, down, left, and right. Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the method for moving the character position of the video semi-permeable built-in television according to the present invention will be described in detail. 3 is a flowchart of a method of moving a character position in an image half-cycle mode according to the present invention. Referring to FIG. 3, by inputting a key to a keypad or a remote controller (not shown) of a television receiver, the microcomputer checks whether the image is in the half-cycle mode or the television mode (S301). Once it is determined that the image is in the half-cycle mode, and the selection song is determined by the user's start key (S303), the microcomputer 28 checks whether the start point has already been designated on the melody of the sound source IC and whether there is a character output (S304). ) If there is a character output, the OSD character position shift mode is performed (S305). Referring to FIG. 4, the character position shifting execution mode is described. When a character position key provided in the key panel or the remote controller is input, the left and right up and down arrow keys are set as keys for shifting the character position. Of course, it is already programmed to operate corresponding to the corresponding key. At this time, by pressing one of the direction keys once, it is moved up, down, left, right. Up, down, left and right position movement limits can be up to the maximum provided by the OSD circuit, and the character table may vary depending on the form. And the adjustment step can be moved by the program step by step from the fine adjustment. Then, if it is determined by step 403 that the phase shift key ↑ is input, step 404 is performed to move the character position on the monitor upward by 1V (step 405) and step 405 is performed to the OSD control register. (Inside the microcomputer, therefore not shown) stores the OSD character position shifted 1V upwards. Then, step 406 is performed to determine whether the moved position is the upper limit value. At this time, if the position of the character moved 1V in the upward direction is determined as the upper limit value supported by the OSD circuit, the character does not move any more in the upward direction no matter how much the pressing key ↑ is pressed. That is, after the step 406 is performed, pressing the phase shift key ↑ once again moves upward by 1V. Then, if the phase shift key ↑ is kept pressed, it is moved up to the upper limit value, and no more is pushed by the step 406 even if it is pressed. On the other hand, if it is determined by the step 407 that the downward movement key (↓) is input, the step 408 is performed to move the OSD character by 1V in the downward direction, and then the step 409 is performed and the OSD moved by 1V in the downward direction. The position of the character is stored in the OSD control register (built into the microcomputer, thus not shown). At this time, if the down shift key ↓ is inputted, 1V is moved downward, and if the down shift key ↓ is inputted, 1V is moved downward by that much. Lastly, when the down shift key ↓ is input, it is determined as a lower limit value by step 410, so that the character does not move further downward. At this time, if it is determined that the user pressed the erase key at step 419 to return the position of the moved character to the original character position fixed by the manufacturer, step 420 is performed to determine the initial position determined by the manufacturer at the current moved position. Return to position Pressing the Clear key while moving to the lowest limit returns to the initial position specified by the manufacturer. At this time, if the erase key is pressed while the position of the character is not moved, the input of the erase key is invalid. On the other hand, if the erase key is not input while the position of the character is moved, the position of the volume level displayed by the volume up / down key is displayed at the position of the moved character until the erase key is input. Therefore, when you want to return the position of the moved character to the original position, enter the erase key in the OSD mode. In the above embodiment, the method of moving in the up and down directions has been described, but the method of moving in the left and right directions is the same as that of the steps 401 to 420 of the embodiment. Therefore, duplicate descriptions will be avoided. In addition, this embodiment is configured to move the position of the OSD characters according to the user's moving key input, but may be configured to automatically move to any part of the screen by setting a default point by the program. As described above, according to the method of moving the position of the character of the built-in TV according to the present invention, the position of the character is moved only at a desired time zone, and if it is not desired, the erase key is immediately returned to its original position. In addition, in memory and erasing, only the mode is configured to operate independently, so that the position of the character can be stored and erased for each mode to satisfy the needs of several people. In addition, even in the positional movement of characters, it is possible to move up, down, left, right, and simultaneous movement at the current position, and the function can be improved only by a pure program within the range provided by hardware, thereby reducing the cost.
