The present invention relates to a method and apparatus for selectively moving a target or a background in an apparatus in which an image half-period and a television are integrally formed. More particularly, the present invention has a built-in image half-period for realizing a partial moving image with a small amount of data. A method of moving the screen of a television.

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 CRTs and speakers. Therefore, the user can select and view the video and audio signals input through the television signal or the external signal input terminal by using the operation button or the 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 image and sound quality than any sound source, but since only 30 songs are contained on one laser disc, it is required to service 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 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.

FIG. 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 the TV and the video accompaniment apparatus, channel selection, video selection, and volume are performed. The controller performs all of the adjustment terminals and the like, and performs all functions of the curve accompaniment, pitch and speed adjustment, and reservation setting in the operation of performing the function of the image accompaniment device.

In particular, in the video accompaniment mode, the audio signal is provided only by the video accommodating device, but the video signal is provided by one of a broadcast signal of a selected channel formed by a television, an externally provided signal, and a graphic signal generated by the video accompaniment signal generator. By doing so, it is possible to provide a lively video corresponding to the contents of the song.

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 22 by the controller 28 is combined with the demodulated color difference signal and output.

As another input of the image synthesizing section 26, graphic signals and text signals from the image accommodating signal generating section 24 are input in the form of R, G, B, BLK and synthesized with the color difference signals provided from the color demodulation section 22. And output to the monitor (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 priority is set in order of the graphic signal, the text signal in the video accompaniment signal generator 24, and the signal in the television signal selector 16. FIG.

Next, in the operation of the audio signal system, the audio signal SVBS, 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 image 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 processor 34, and after the reverberation sound processing and the equalizing process 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 WOOFER.

The voice signal VOICE introduced through the microphone is combined with the accompaniment signal of the image accompaniment signal generator 32 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 for generating graphic signals and text signals, an auxiliary signal generator 244 for generating accompaniment sounds, Controls the operation of the graphic / text signal generator 242 and the accompaniment signal generator 244, inputs the image accompaniment controller 246 for generating a pseudo synchronous signal, and graphic / text information and sound source information that can be provided from the outside. An external interface (not shown) is provided to the graphic / text signal generator 242 and the accompaniment signal generator 244.

The graphic / character signal generator 242 includes a graphic memory for storing graphic information, a character memory for storing character information, a graphics / character processor for combining graphic information read from the graphic memory and character information read from the character memory, and the graphic. And a digital-to-analog converter for outputting the character processor's output. 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 signal. 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.

The graphic / text signal generator 242, the accompaniment signal generator 244 and the image accompaniment controller 246 are interconnected by a bus having data, address and control signal lines. The microprocessor 246a of the image accompaniment controller 246 controls such that graphic signals, text signals, and accompaniment signals corresponding to the designated tunes are generated through the bus. The synchronization signal generator 246b generates a pseudo synchronization signal.

The interfacer 246c receives the remote control command from the remote controller and transmits it to the microprocessor 246a. The remote control command transmitted from the remote controller is simultaneously applied to the microcomputer 28 of FIG. 2 and the image accompaniment control unit 246 of FIG. In other words, if the remote control command is a television control command, the microcomputer 28 operates. If the video accompaniment control command is performed, the video accompaniment signal generator 24 operates.

The pseudo synchronous signal PS is used to maintain synchronization between the graphic / text signal generator 242 and the image accompaniment signal when the graphic signal from the image accompaniment signal generator 24 is applied to the first selector 20. will be. By the way, when the normal television signal is outputted, the synchronization of the graphic / text signal generator 242 is maintained by the synchronization signal H / V generated by the color demodulation unit 22.

In the operation of the accompaniment signal generator 244, data such as the pitch, the length and length of the sound, and the tone (type of instrument) for each song are recorded in the sound source information memory 244a according to the MIDI standard. The sound source information read from the sound source information memory 244a is input to the sound source information processor 244b, and then formed as serial data of the stereo L channel and the stereo R channel and transmitted to the digital / analog converter 244c.

The analog stereo L channel and stereo R channel signals output from the digital / analog converter 244c may be combined with external voice signals such as a microphone by the voice synthesizer 38 and transmitted to the second selector 32.

On the other hand, graphic information is stored in the graphic memory 242a of the graphic / character signal generator 242, and lyrics information corresponding to each song is stored in the character memory 242b. The graphic information and the character information read out from the graphic memory 242a and the character memory 242b are combined by the graphic / character information processor 242c and then input to the digital / analog converter 242d. The digital-to-analog converter 242d outputs graphic / text signals in the form of R, G, and B.

Since the video accommodating device is integrally formed and formed in the television as described above, a user can be provided with a low cost of purchase and very convenient in use, compared to purchasing a separate television set and the video accommodating device set.

However, in the conventional TV with a built-in image repeating cycle, the graphic is not set arbitrarily, but when the user presses the graphic mode key, the graphic is executed according to an internal program, thereby narrowing the user's selection of the graphic. .

Therefore, the present invention is to solve the above problems, an object of the present invention is to mix the moving object to the animation (background graphics) in the graphic mode to move the moving object or the background screen freely built-in The present invention provides a method of moving the screen of a television.

When the target and background are synthesized by the combining unit 251, the scenario memory 250 outputs an audio signal. Is output to be output through the digital-to-analog converter 244c.

FIG. 5 shows a picture of an embodiment according to the present invention. The monitor CRT shows a combination of a background graphic 300 and a target 302. FIGS. 5A and 5B show a target. The plane 302 is moved, and the background screen 300 is displayed in a fixed state. 5C and 5D illustrate a state in which the target 302 is fixed and only the background screen is moved. Therefore, the user may move only the target (background), and the background (target) may be fixed and displayed on the monitor, which will be described in detail with reference to FIG.

6 is a control flowchart for the screen moving method according to the present invention. When power is applied, the microcomputer 28 determines whether the signal input from the remote control or the command input unit 42 is a television operation signal (step). S ₁ ). If the signal currently input is a signal for television operation, the program proceeds from step S ₁ to step S ₂ so that a general television function can be performed.

However, as a result of the discrimination in step S ₁ , if the current input signal is not a television mode signal, the program proceeds from step S ₁ to step S ₃ . the flow proceeds to step (S _4).

By the way, when graphics mode signal is input (step S _5), the microcomputer 28 sets a monitor (CRT) to the initial state (step S _6). In this case, when the target mode is selected, the microcomputer 28 controls the microprocessor 246a, which controls the target storage memory 242a. At this time, the program proceeds from step S ₇ to step S ₈ . In step S ₈ , it is determined whether or not to move the target (for example, an airplane).

If the target is to be moved, the program proceeds from step S ₈ to step S ₉ , but if the target is not moved, the program proceeds to step S ₁₂ . On the other hand, in step S ₉ , the background is selected. When the background selection switch is increased, the microcomputer 28 provides a control signal to the microprocessor 246a to store a plurality of backgrounds stored in the background storage memory 242e. Among the backgrounds, any background data, for example, data for the background 300 shown in FIG. 5 is read.

After the background is selected, it is determined whether or not to move the background (step S ₁₀ ). If the background is not moved, the program proceeds from step S ₁₀ to step S ₁₁ , and the background movement is performed. If desired, the program proceeds to step S ₁₂ .

Therefore, in the case of step S ₁₁ , the target is moved and the background is fixed as in (a) and (b) of FIG. 5, and in the case of step S ₁₂ , (c), As shown in (d), the target is fixed and the background is moved.

After the background and the target are set in this way, when the user presses a start button (not shown), the program proceeds from step S ₁₃ to step S ₁₄ , and the monitor CRT shows (a) to ( Background and target may be displayed in the same manner as d). That is, the target may move as shown in (a) and (b) of FIG. 5, and the background may move as shown in (c) and (d) of FIG. 5.

When the cancel key is pressed in the background and target display modes in this way, the program is terminated (step S ₁₅ ).

As described above, according to the present invention, the screen can be moved freely, which can be useful for children's fairy tales.
