The present invention relates to a method of selecting a menu of a compact disc video song accompaniment apparatus, and in particular, by rhythm, year, and genre, from a song accompaniment compact disc in which thousands of music lyrics and accompaniment data and thousands of background data are recorded. The present invention relates to a menu selection method of a compact disc video song accompaniment device capable of selecting songs.

Conventional song accompaniment apparatus, also known as karaoke apparatus, uses magnetic tape, video disk, so-called laser disk or semiconductor memory as recording medium.

The karaoke apparatus using the magnetic tape is not a random search due to the characteristics of the magnetic tape, so high speed search is difficult. Karaoke devices that use video discs can be searched at high speed, but the lyrics are superimposed on the background of the fairy tale and the song accompaniment is played back. Limited to overtures. Therefore, 50 discs must be prepared for accompaniment of 1000 songs, so it is a burden to purchase a large number of discs to enjoy various songs, and even if a large number of discs are provided, the disc has to be replaced frequently. It was uncomfortable.

Therefore, the karaoke shop has had the economic burden of preparing several or ten video disc players and having at least one disc changer to replace the disc at that time or to have an expensive automatic disc changer. Karaokes using semiconductor memories can record hundreds of songs, but up to now, the cost of semiconductor memories is expensive, and it has been economically expensive to use large amounts of memory to express image data suitable for songs.

On the other hand, a karaoke device that uses a compact disc as a recording medium has also been introduced. Since the CDG karaoke device writes graphic data as a sub code, the amount of information that can be recorded is limited, so that the screen configuration can provide a high quality image of more than graphic level. Since it is difficult and can not record more than 99 songs because of using the table of contents of the CD, there is a problem that a large amount of discs must be purchased in order to enjoy a lot of songs like a video disc.

More specifically, the CD is a recording medium capable of storing optically modulated digital data signals on a disc having a diameter of 12 cm in a large capacity (up to 600 M bytes), and an audio-only CD-DA containing digital audio data, digital audio data and text. There are CD-G and CD-EG that contain data and graphic data to provide lyrics and graphic background as well as audio, and CDV which contains digital audio and video data. In addition, there are CD-ROMs for recording computer data and using them in databases, electronic publishing, etc., and CD-1 for recording audio, video, text and computer data for multimedia use.

The physical recording format of such CDs is based on the recording format of CD-DA. The data recording area of the CD is roughly divided into a lead-in area LIA, a program area PMA, and a lead-out area LOA. The CD-DA records digital audio data in the PMA and the program's time content, or table of contents information, in the LIA. Therefore, the CD player reads the table of contents recorded in the LIA before playing and seeks the selected program to play the program. The LIA has eight subcode channels called P, Q, R, S, T, U, V, and W. The table of contents information uses the Q channel and displays the song number and index of up to 99 programs from 1 to 99. CD-G adds a graphic function that displays karaoke lyrics and song images using R-W sub-code channels not used in CD-DA.

Since such CD-DA or CD-G searches PMA programs by referring to the contents of the LIA, the number of programs that can be stored in the PMA is limited.

For example, the maximum capacity of one CD is 800M bytes, so 8,000 still pictures of 100K bytes can be recorded. Therefore, 8,000 catalog information cannot be included in the LIA. The CD-ROM and CD-I reconstruct and record or process an audio data block composed of 98 frames, which is a data processing unit of a CD-DA, in units of sectors. The CD-ROM driver is connected to a host computer (personal computer) and performs playback operation dependently by a CD-ROM operating program mounted on the hard disk or floppy disk of the host computer. Therefore, CD-ROM-specific host computers must be used, so compatibility between systems is inevitably required, and it is limited to spread in each home.

In order to make up for the shortcomings of the CD-ROM, the CD-I has a computer, a character playback circuit, an image playback circuit, an audio playback circuit and a computer data playback circuit. Would solve it. In other words, the CD-I system may be referred to as a reproduction-only computer in which a hard disk or floppy disk of the computer is replaced with a CD-I disk. Such a CD-I system can access virtual data only by applications stored on disk in the operating system environment, which is almost the same as a computer. Therefore, specific OS and applications are inevitably required. The disadvantage is that the cost increases with development. In addition, it is inconvenient that the computer cannot directly access the data location stored on the disk, but must be accessed through an OS or an application program. U.S. Patent 5,243,582 discloses a playback apparatus for a karaoke disc. In the above patent, by recording a file TOC in a data area of a compact disc and addressing the data area with reference to the file TOC, the capacity of the TOC can be expanded to 99 or more, so that an arbitrary position of a song can be selected and a specific song can be selected. Disclosed is a technique capable of repeatedly playing back a section of.

SUMMARY OF THE INVENTION An object of the present invention is to provide a compact disc video song accompaniment apparatus capable of reproducing thousands of song accompaniments together with a high-quality background for a song atmosphere in order to solve the problems of the prior art as described above. By selecting songs by rhythm, year, and genre, the present invention provides a menu selection method for enjoying a variety of song accompaniment.

The menu selection method of the video song accompaniment playback apparatus of the present invention for achieving the above object comprises music from a compact disc including a second table area in which music index table information is recorded and a second data area in which thousands of music information is recorded.

The selection items include the challenge difference mode and the medley mode, and the classification items include rhythm, age, and genre classification.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

The compact disc for accommodating a video song of the present invention (hereinafter referred to as a CD-OK disc) has a lead-in area LIA, a program area PMA, and a lead-out area LOA as in the case of a conventional CD-DA disc. 1 shows a data structure of a Q channel in LIA. The 98-bit Q channel data structure consisting of the second channel bits of the eight channels of P, Q, R, S, T, U, V, and W of 98 frames is 96 bits except for the first 2 bits of sync bit (12). It is composed. A 4-bit control bit 14 and a 4-bit address bit 16 are followed by a 72-bit data bit. Data bits include an 8-bit track number code 18, an 8-bit pointer 20, a 24-bit address (minutes, seconds, and frames) 22, an 8-bit interval bit (24), and 24 bits. Is composed of a pointer address (PMIN, PSEC, PFRAME) (26). Next to the data bit is a 16-bit CRC code 28. In LIA, the track number code (TNO) of the Q channel is decimal zero. In the LIA, the contents of the contents recorded on the disk, that is, the contents table (TOC) are recorded. The TOC is composed of a pointer 20 and a pointer address 26 of the Q channel. The pointer address 26 represents the minute, second, and frame value of the start point of each track of the PMA having a specific track number.

2 shows an example of a TOC according to the present invention. When the pointer value is 01h, the minute, second, and frame data indicate the start address of the first track of the program area. When the pointer value is A0h, PMIN indicates the first track number in the program area. When the pointer value is A1h, PMIN indicates the last track number in the program area. When pointer value A2h, minute, second and frame data indicate starting address of LOA. Therefore, as described above, the TOC configuration of the present invention has one track number and the values of the pointers A0h and A1h are the same.

Referring to FIG. 3, the program area PMA of an embodiment according to the present invention is largely divided into a disc label area 30, a disc description area 32, a first table area 34 and a second table of a CD-ROM. The area 36 includes a first data area 38 and a second data area 40. At least one CD-DA track may be included between the second data area 40 and the LOA. In this case, a pointer and an address of this track are additionally set in the TOC. Here, the disc label area 10 adopts the ISO 9660 format as it prescribes the well-known CD-ROM format.

Referring to FIG. 4, the disc description area 32 has a predetermined time interval, that is, an absolute address, as a start address A from a start frame of 00 minutes 00 seconds, which is a start address of the program area PMA. VERSION X X 'Disc identification information and version number are recorded in ASCii code. The disc description area 32 is composed of two sectors in mode 1 of the CD-ROM format.

Referring to FIG. 5, the first table area 34 is index index and start address and characteristic information of each background information of the first data area 38 in which thousands of background information are recorded. The background index table of FIG. 3 is recorded, and has a start address B of FIG. 3. Each index information includes a 2-byte index 42, a 1-byte minute, a 1-second second, and a 1-byte frame. Each of the background information includes a start address 44 and one byte of feature information 46. The one-byte feature information 46 includes background information such as mountain, sea, forest, person 1, person 2, building, harbor, ship, car, train, flower, bird, animal, sky, night view, foreground,. Information for displaying an image group in which groups of background images having similar images are formed by .. etc., 00h indicates the start of an image group, and 01h indicates an image group sequence. Therefore, for example, if the required number of sectors in the background address table for indexing 4000 still images is calculated,

(6 bytes * 4,000 wallpaper information) / 2048 = 11.78 sectors

Therefore, 12 sectors are required for the mode 1 sector.

When the first data area 38 has a start address D, a plurality of background information is sequentially recorded in the index number order. As shown in FIG. 6, each background information is composed of two bytes of pixel information 48 consisting of a start bit of 15 bits and an RGB 555 code of 15 bits, a continuous bit of 15 bits, and a run length code of 15 bits. And 360-dot * 240 lines of still picture information compressed into 2 bytes of run-length information 50. Therefore, the background information takes (360 * 240 * 2) /2048=84.37 sectors when coding with RGB555, but when runlength coding, it is compressed to about 40 sectors in case of naturalization, and greatly compressed for graphic screens. It is compressed to about 5 sectors. Therefore, 400 megabytes is required for recording 4000 naturalized images.

Referring to FIG. 7, each background screen information includes a header 52, a body 54 composed of compressed background screen data, and a taylor 56 indicating the end of each background screen information. The header 52 includes a 'CD-OK' indication, a pointer XX indicating the start position of the body 54 and a pointer YY indicating the start position of the taylor 56.

Referring to FIG. 8, the second table area 36 constitutes a music index table consisting of the index number 58, the start address 60, and the classification information 62 of each music information. A start address 60 of music information consisting of a 2-byte index number 58, a 1-byte minute, a 1-second second, and a 1-byte frame, and the classification information of each 1-byte music information 62 ) The feature information 62 is identification information according to the type of music information. For example, as shown in FIG. 9, the feature information 62 displays the upper 4 bits of the 1 byte as the BCD code, indicating that 0 is not flexible, and 1 to 7 (column direction) are flexible rhythms. Indicates the type. The lower 4 bits are represented by the BCD code. When the upper digit is 0, 2 to 8 (low direction) indicate the genre type, and when the non-zero is 0, it indicates the timeline of the song. The second table area 36 is a mode 1 sector similar to the first table area 34 and has a size of 12 sectors.

Referring to FIG. 10, when the second data area 40 has a start address E, thousands of pieces of music information are recorded in index number order. Each music information has a start address in the second table area 36. ) Is largely comprised of a header 64, a body 66 and a taylor 68. The body 66 includes accompaniment data 70, lyrics data 72, and background screen order table 74 having a MIDI format. In the header 64, the identification information " CDOK " and the pointer WW indicating the start of the body 66, the pointer XX indicating the start of the character data 72, and the pointer YY indicating the start of the background screen order table 74 are shown. And a pointer ZZ that designates the beginning of the taylor 68. The background screen order table is composed of group information of the background screen according to a preset display order of the background screens of the music when the accompaniment data is output. Here, the group information of the background screens according to the preset display order is prepared to be edited into screens that match the image or mood of the music.

A method of reproducing a disk recording medium having such a signal format will be described below with reference to FIG.

In the method of reproducing a disc recording medium of the present invention, at the beginning of reproduction, the disc content table TOC is read from the lead-in area LIA of the CD-OK disc to obtain the start address 0 of the program area PMA, which is started. Starting addresses C and D of the first and second table areas 34 and 36 are found from the address 0, and the background index table 35 and the music index table 37 are read from the disc. For example, when the user selects No. 1, the music index table 37 reads the address M2 of the music index 0001 corresponding to No. 1 and starts the address M1 from the second data area 40 of the disc. The music information 63 having the address is read. Reference is made to the display (G3-G1-G2-G3-G2-G1) of the background screen from the background screen order table 74 by the pointer value YY from the header 64 of the music information 63 that has been read. The starting address of the wallpaper indexes (0010-0001-0005-0011-0006-0002) corresponding to this order is referred to the wallpaper index table 35, and the referenced address (V10-V1-V5-V11-V6-V2) is referred to. Background image information having a start address) is sequentially read from the first data area 38 of the disc. Lyric data (W1-W2-W3) corresponding to background information (P1-P2-P3-P4-P5-P6) corresponding to accompaniment data (U1-U2-U3 --- UN) of music information 63 --- WN) overlaps the output.

14 shows a block diagram of the internal circuit diagram of the set. The structure of the playback apparatus of the present invention is largely divided into a CD playback section and a CD-OK playback section. The CD reproducing unit includes a spindle motor 116 for rotating the disc 114, an optical pickup 118, an RF amplifier 120, a servo controller 121, a digital signal processor 122, a main controller 124, and a sub controller. 126, disc deck drive unit 128, display unit 130, command input unit 132, digital-to-analog converter 134, audio signal selector 136, audio output amplifier 138, audio output terminal 140 It includes.

The CD-OK playback unit includes a CD-ROM decoder 142, an interface unit 144, a system memory unit 148, a control signal generator 149, a MIDI data transmitter 150, a sound source processor 152, and an audio converter ( 154, digital echo processing unit 155, audio input amplifier 156, microphone ohmic input terminal 158, microphone sound detection unit 160, video memory unit 162, image conversion unit 164, superimposing means 166, synchronous signal generator 168, synchronous detector 170, video input amplifier 172, video selector 174, video output amplifier 176, video input terminal 178, video output terminal And 180. The main controller 124 controls the switching of the audio selector 136 and the video selector 174. The VS signal is a switching control signal of the video selector. 182 is a compact disc graphics decoder.

15 is a circuit diagram of a clock generator of the control signal generator 149 according to the present invention. The clock generator includes a horizontal synchronous separator 182, a phase difference detector 184, a synchronous detector 196, a first oscillator 192, a second oscillator 194, a signal selector 190, and gate means. 186 and the frequency divider 188.

The synchronizing signal separator 168 applies the complex synchronizing signal to the one-shot circuit composed of the resistor R1 and the capacitor C1 through the inverter G1, passes through the one-shot circuit, and removes the vertical synchronizing signal and the horizontal synchronizing signal EHSY. Only output through the inverter (G2).

The phase difference detector 184 is supplied with an external horizontal synchronization signal, which is an output of the synchronization signal separator 10, to a clock terminal of the first flip-flop FF1, a 5V power supply voltage is applied to the data input terminal and the set terminal, and a clear terminal is applied to the clock terminal of the first flip-flop FF1. The positive output signal of the second flip flop FF2 is applied. The internal horizontal copper signal IHSY is applied to the clock terminal of the second flip-flop, the ground is connected to the data input terminal, the power supply voltage is applied to the clear terminal, and the positive output signal of the first flip-flop is applied to the set terminal. The positive output signal of the first flip flop is provided as a phase difference detection signal PD between the external horizontal synchronization signal EHSY and the internal horizontal synchronization signal IHSY.

The synchronous detector 196 provides the energized output signal and the negative output signal of the monostable multivibrator MM1 for inputting the external composite synchronous signal to the trigger input terminal as a switching control signal of the signal selector 600. The control signal of the gate means 70 is provided. The resistor R3 and the capacitor C2 are for setting the time of the monostable multivibrator MM1 and the resistor R2 is a pullup resistor. Therefore, when the external composite synchronization signal ECSYNC is applied, the trigger pulse is continuously applied to the trigger terminal, so that the constant output signal is kept high and the negative output state is kept low. Then, when there is no input of the external composite synchronous signal, the constant output signal remains high for a time determined by the resistor and capacitor, and then transitions to a low state. Therefore, when the external complex synchronous signal is applied, the signal selector 90 selects and outputs the first oscillation signal 58.5MH _{Z of} the first oscillator and the second oscillation signal of the second oscillator disappears when the external complex synchronous signal disappears. Select (57.252MH _Z ) to print. The first oscillation signal is a reference oscillation signal for synchronizing with the video signal reproduced from the laser disk, and the second oscillation signal is a standard oscillation signal for synchronizing with the video signal of NTST television system. In addition, the gate means 186 passes the phase difference detection signal PD in the low state of the sub-output signal and blocks it in the high state.

The dispenser (188) when the internal synchronous clock signal is to generate a frequency divider to the input 57.252MH _Z oscillating signal and when the external synchronization input the oscillation signal of the 58.5MH _Z is phase locked to the external horizontal synchronizing signal a frequency division clock signal, Occurs. That is, during external synchronization, when the internal synchronization is correct, the division operation is reset by the phase difference to generate a clock signal matched to the external horizontal synchronization.

The synchronization signal generator 168 inputs the divided clock signal to generate a vertical synchronization signal, a horizontal synchronization signal, a vertical blanking signal, a horizontal blanking signal, and the like. The generated internal horizontal synchronizing signal is provided to the phase difference detector. Therefore, the phase is creep-formed to generate a phase locked signal to the external synchronization signal during external synchronization.

16 shows a block diagram of a synchronization signal generator 168 according to the present invention. FIG. 17 shows waveforms of respective parts of FIG. The synchronization signal generator of the present invention includes a front end detector 198, an external synchronous input detector 200, an external vertical synchronous front end detector 202, a field discriminator 204, a horizontal synchronous generator 206, The vertical synchronization generating unit 208, the signal synthesizer 210, and the synchronization selector 212 are included.

The tip detector 198 inputs the external composite synchronization signal ECSYNC of FIG. 2 to output the pulse tip detection signal SYNCP of FIG. 17 that detects the tip of each sync pulse signal.

The external synchronization input detection unit 200 includes a flip-flop FF1 for synchronizing the pulse tip detection signal SYNCP with the clock signal CLK, and a flip-flop for synchronizing the internal synchronization recovery signal V256 with the clock signal CLK. FF2 and the output of the flip-flop FF2 when the output of the flip-flop FF1 is cleared to generate an external synchronous input detection signal VD0 in a low state and the output of the flip-flop FF1 remains high. And a flip-flop FF3 for outputting the external synchronization input detection signal VD0 in a high state by clock input. Therefore, when there is no input of the pulse front end detection signal SYNCP of the external composite synchronization signal ECSYNC, the output of the flip-flop FF1 remains high and the output of the flip-flop FF2 goes from the low state to the high state. At the transition point, the flip-flop FF3 generates the external synchronization input detection signal VDO in a high state. When there is an input of the pulse tip detection signal SYNCP, the output of the flip-flop FF1 remains low, so the external sync input detection signal (the output of the flip-flop FF3, regardless of the output of the flip-flop FF2) VDO) will remain low. That is, the external synchronization input detection signal VDO is kept low when there is an input of the external synchronization signal, and is kept high when not present.

The external vertical synchronization tip detection unit 202 decodes the counter value 214 and the counter value 214 that are cleared by the pulse tip detection signal SYNCP and count the clock signal CLK, and in response to the decoding value, the respective synchronizations are decoded. The vertical synchronization pulse tip detection means 216 for detecting the pulse width of the pulse to detect the tip of the external vertical synchronization signal and the vertical initial value loading signal VLD in response to the tip detection signal VSYP of FIG. And pulse forming means 218. The counter 214 is cleared by every pulse front detection signal SYNCP to count the clock signal CLK. The vertical synchronization pulse tip detecting means 216 has a pulse width of 4.8 microseconds for the horizontal synchronization signal (246 in FIG. 17), 2.3 microseconds for the equalization pulse (248 in FIG. 17), and a vertical synchronization pulse (250 in FIG. 17). ), Focusing on 27 microseconds of width, if the sync signal ECSYNC transitions from the low state to the high state under the first decoding value (a value set between 2.3 and 4.8 microseconds), it is an equalization pulse and the first coding value. When the sync signal ECSYNC transitions from the low state to the high state between the and the second coding value (a value set between 4.8 and 27 microseconds), the horizontal sync signal and the sync signal ECSYNC is low above the second decoding value. If it is maintained, it is recognized as a vertical synchronous pulse. The first decoding value is a suitable value between 2.3 and 4.8 microseconds and the second decoding value is set to a suitable value of 4.8 microseconds or more. Accordingly, the vertical synchronizing pulse tip detecting means 2160 detects only the vertical synchronizing pulse (VSY of FIG. 17) among the external composite synchronizing signal ECSYNC and converts the detected vertical synchronizing pulse VSY to the internal vertical synchronizing signal (VSYNC of FIG. 17). ) Outputs the front end detection signal VSYP of the external vertical synchronization signal. The tip detection signal VSYP is generated as a vertical initial value loading signal VLD synchronized with the horizontal end signal YOP of FIG. 17 and the horizontal end signal H / 2 shifted 180 degrees through the pulse forming means 218. do.

The field discrimination unit 204 detects the odd / excellent field based on the multiple detection signal VSYP of the external vertical synchronization signal and the internal reference signal HLDE shown in FIG. 17 and the external synchronization input detection. Selecting means 222 for selecting an output signal of the discriminating means 220 during external synchronization in response to the signal VDO and a vertical blanking signal VBLK for internal synchronization, and an output signal of the selecting means 222; And pulse forming means 224 for outputting to the field discriminating means E / ODD in FIG. 17 in synchronization with the clock signal CLK. The internal reference signal HLDE is a signal for keeping a predetermined period including the 2/1 point of the horizontal period low. Therefore, in the odd field, the front end detection VSYP of the vertical synchronization signal transitions from high to low in the high period of the internal reference signal (238 in FIG. 17), and in the even field, the low period of the internal reference signal HLDE in the even field. In step 240 of FIG. 17, the tip detection signal VSYP transitions from a high state to a low state. Therefore, in the odd field, the field discrimination signal E / ODD is shifted from the high state to the low state and is kept low, while in the even field, the field discrimination signal E / ODD is shifted from the low state to the high state to maintain the high state.

In the score determination routine of FIG. 28, the coloring speed of the corresponding character is initialized to match the accompaniment beat for the coloring of each character (1202). ) Coloring of the corresponding character is started by writing the coloring data to the video memory unit 162 and screen refreshing the background screen of the video memory unit 162 to which the coloring data is written. It is checked whether the coloring has started (1204), and if it is started, the value CN of the first counter is increased by 1 (1206) and the output signal of the microphone ohmic detection unit 160 to which microphone ohms are applied through the microphone connected to the microphone connection terminal 158. It is checked whether the level of the MIC is low (1208). If it is low level, it is checked whether the flag value is 0 (1210). If it is 0, the value CM of the second counter is increased by 1 and set to the flag value 1 (1212). Otherwise, feed back to step 1208. If the input level is not low in step 1208 or the flag value is not 0 in step 1210, step 1214 is performed. Therefore, if the level of the output signal MIC of the microphone ohmic detection unit 160 is low for at least one character coloring time, the microphone input is counted during the character coloring. If the sampling frequency is 3 or more times, it is checked whether the coloring for one character is finished (1216). If it is finished, the flag value is set to 0 (1218). If the accompaniment stop command or the selected accompaniment is completed (1220), or 1202 Feedback to the stage. Therefore, input checking is performed on all characters until the song is completed. When it is stopped or terminated in step 1220, the ratio of the number of checked characters of the microphone input to the total characters with the values of the first and second counters is calculated (1222). If the obtained value X is less than or equal to 30 (1236), the score is output as 30. (1236) If it is more than 30 and less than 70 (1226), it outputs a random value from 31 to less than 70 (1238), and if it is more than 71 and less than 75 (1228), it cycles 71-75 and scores at that time. If the output is 1240, less than 90 from 76 (1230), output the scored score X (1242). If the score is more than 90 in step 1230, the fanfare setting is checked (1232). If the fanfare setting is not present, the X value is outputted (1244). If the fanfare is set in operation 1232, the fanfare is output through the sound source processing unit 152, an X value is output (1234), and the output value is displayed through the video memory unit 162 as shown in FIG. 27D.

As described above, the present invention checks whether the microphone is input within the coloring time of each character, and determines and displays the checked result as a score so that the score does not come out well if the beat does not match. In the high score of 76 or more, his song score can be properly evaluated, and in the lower stages, he can process it in three stages so that the appropriate bonus score can be evaluated so that he can enjoy more fun.
