The present invention relates to a method of performing a reserved song mixing function of an embedded video half-period television, and more particularly, to a reserved song mixing function added to a video accompaniment function of a built-in video half-period television, corresponding to a reserved song number input by a plurality of users. The present invention relates to a method of performing a reserved song mixing function of a video semi-permeable built-in TV having a variety of menus that can be multiplied by a random mix of music pieces, and by arbitrarily designating a mixed reserved song and a user.

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 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 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. The connection between the video and the music is not only deteriorated, but since the songs are limited to about 15 songs on a compact disc, 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.

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 the adjustments of the control terminals, and the like, and performs all the functions of the video accompaniment device, including curve tack, pitch and speed adjustment, and reservation setting.

In particular, in the video accompaniment mode, the audio signal is provided only by the video accompaniment 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.

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 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 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 accommodating signal generator 24 to the image synthesizing unit 26, the OSD signal and the image of the control unit 28 are applied. The priority is set in order of the graphic signal, the text signal in the 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 operates the graphic / text signal generator 242 for generating graphic signals and text signals and the accompaniment signal generator 244 for generating accompaniment sounds. And input the graphic / character signal generator 242 and the accompaniment signal generator 244 by inputting graphic / character information and sound source information that can be provided from the outside. An external interface (not shown) is provided.

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 D / A converter for digital / analog conversion of the output of the character processor.

The accompaniment signal generator 244 digitally / analog converts the output signals of the sound source information processing unit and the sound source information processor, which input sound source information stored from the sound source memory, the sound source memory, and convert the sound source information into an 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 from a remote control device (not shown) And a synchronization signal generator for generating a pseudo-synchronous signal equivalent to a registered signal of a television signal and an interface for transmitting a command to a microprocessor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a method for performing a reserved song mixing function of a video semi-permeable television according to the present invention will be described in detail with reference to the accompanying drawings.

3 is a flowchart showing a method of performing a reserved song mixing function of a TV having a built-in image repeating period according to the present invention.

Referring to FIG. 3, it is determined whether the image accompaniment mode is selected (S301). If the video accompaniment mode is not selected, the television mode is performed (S302).

If the video accompaniment mode is selected, it is determined whether the reserved song mixing function is set (S303). If the reserved song mixing function is not set, a general accompaniment function is performed (S304).

If the reserved song mixing function is set, the initial screen is displayed on the screen (S305). At this time, the initial screen is displayed with a message for inputting the number of people together with the background screen arbitrarily set by the user's taste.

Enter the number of people (S306). At this time, the input of the number of people using the numeric keypad mounted on the keyboard or the remote control. When the number of persons is input, the reserved song input screen is displayed (S307).

When the reserved song input screen is displayed, the reserved song number is input (S308). It is determined whether the input of the reserved song number is completed (S309). If the input of the reserved song is not completed, the process returns to the reserved song number input step (S308). At this time, the number of digits of the reserved song number is arbitrarily set, compared with the number of digits of the reserved song input by the user, and if it is the same as the set digit, it is set to determine that the reserved song input is completed.

When the reserved song input is completed, the microcomputer randomly mixes the corresponding person number and the reserved song number (S310). When the mixing is completed, the microcomputer displays one of the mixed corresponding person number and the reserved song number on the screen (S311).

The initial number of advances is set to 1 (S312). When the setting is completed, the image accompaniment function is performed (S313).

If it is determined that the song is finished (S314), if the song is not finished, it returns to the video accompaniment function performing step (S313) again, and when the song ends, it is determined whether the number of times and the number of the same number is the same (S315) If the number of people is the same value, the process is finished. If the number of times and the number of people is different, set the value of the current number of times plus 1 as the new number of times (S316), and then mix the number of the person and the reserved song number. (S316). When the corresponding person number and the reserved song number are displayed, the process returns to step S313 to perform the image accompaniment function.

For example, to describe in more detail as follows.

Determines whether image accompaniment mode is selected. If the image accompaniment mode is not selected, the television mode is performed. If the video accompaniment mode is selected, it is determined whether the reserved song mixing function is set. If the reserved song mixing function is not set, the normal image accompaniment function is performed.

When the reserved song mixing function is selected, the initial screen is displayed on the screen. In this case, the initial screen displays a message for inputting a title arbitrarily selected by the user and the total number of users. At this time, the state displayed on the screen is shown in [Table 1].

The user enters the number of people. For example, if the total number of people is 4, look at the input process as follows [Table 2] and [Table 3].

When the number of persons is input, the screen is displayed on the screen in which the reserved song number can be entered. The state at this time is shown in [Table 4].

Here, the numbers 1, 2, 3, and 4 for inputting the reserved song number are the corresponding numbers of the respective users. This is set arbitrarily among users.

When the user corresponding to No. 1 selects the song of '1234', the state displayed on the screen is shown in [Table 5] to [Table 9].

When the first user's song number input is completed, the cursor is automatically positioned at the first digit of the next user's song number.

By repeating the above process, if all four reserved song numbers are input, it is determined whether the input is completed. When the entry is complete, the cursor is automatically removed and the screen displays the reserved number and the person's number. The state at this time is shown in [Table 9].

When all the input is completed, the microcomputer selects a song corresponding to the input song number from among the plurality of songs stored in the memory, and then randomly mixes the song with the corresponding number.

When the mixing is complete, the microcomputer optionally displays one of the mixed numbers. For example, when the third user selects '2345' and the song corresponding to the number is 'emoji', the state displayed on the screen is shown in [Table 10].

When the corresponding person number, the reserved song number, and the song title are displayed, the microcomputer sets the number of times to be '1'. Here, it is preferable to display a message on a specific portion of the screen so that the user knows that the number of times of progress is set. In this case, the displayed state is shown in [Table 11].

When the setting is completed, perform the video accompaniment function. If it is determined that the song is finished and the song is not finished, the video accompaniment function is continued again, and when the song is finished, the microcomputer compares the number of progresses and the number of people. Here, if the number of times and the number of people are different from each other, the microcomputer sets a value of one plus the current number of times as a new number of times. When the setting is completed, randomly selected and the corresponding person number, song number and song number are displayed. At this time, the state displayed on the screen is shown in [Table 12].

If the number of steps and the number of people is the same value in the step of repeating the above process and comparing the number of times and the number of people, it is determined that all the users are covered once and finishes all the processes.

Here, when the microcomputer performs an image accompaniment function by initially selecting one of the mixed money numbers, the corresponding person and the performed song are removed from the memory so that the same user does not have two chances.

On the other hand, in the above case, if there are four users, and one user wants to proceed more interesting by inputting two or more reserved songs, the number of the person mentioned above and the performed song are changed to the same song without removing from the memory. You can mix it so that more than one person can sing, or that the same person can sing multiple songs.

As described above, according to the method of performing the reserved song mixing function of the built-in video accommodating TV according to the present invention, after mixing a plurality of music numbers reserved by a plurality of users to the video accompaniment function of the built-in video accommodating TV, The user's interest was increased by selecting one of the person's number and the reserved song number to perform the image accompaniment.
