The present invention relates to a compact disc video song accompaniment playback apparatus having a voice service function. In particular, the present invention relates to a compact disc video song accompaniment reproducing apparatus that reads data of a selected song from a song accompaniment compact disc in which thousands of music lyrics and accompaniment data are recorded. The present invention relates to a compact disc image song accompaniment reproducing apparatus capable of playing a song accompaniment with a background of lyrics overlapping and providing a voice service according to each operation.

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

Karaoke devices using magnetic tapes are difficult to search at high speeds because they cannot be randomly searched due to the characteristics of magnetic tapes. Karaoke devices that use video discs are capable of high-speed search, but they display superimposed lyrics on a fairy tale background and play back song accompaniment. Limited to. Therefore, 50 discs must be prepared for accompaniment of 1000 songs, so it is burdensome to purchase a large number of discs to enjoy various songs, and it is inconvenient to use the discs frequently even if a large number of discs are provided. It was.

Thus, the karaoke shop has had the economic burden of preparing several or tens of video disc players and having at least one disc changer at that time to replace the disc or to have an expensive operating disc changer. Karaokes that use semiconductor memory can record hundreds of songs, but up until now, it has been economically expensive to use a large amount 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 the table of contents format of the CD is used, 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). The CD-DA, which contains digital audio data, and digital audio data, CD-G and CD-EG, which contain text and graphic data, provide lyrics and graphic backgrounds as well as audio, and CDV, which contains digital audio and video data.

There are also CD-ROMs for recording computer data and using them in databases, electronic publishing, and the like, and CD-Is for recording audio, video, text and computer data for multimedia and the like.

The physical recording format of such CDs is based on the recording format of CD-DA. The data recording area of the CD is largely divided into a lead-in area LIA, a program area PMA, and a lead-out area LOA. The CD-DA records the digital audio data in the PMA and the time contents of the program, that is, the table of contents information, in the LIA. Therefore, the CD playback apparatus reads the characters recorded in the LIA before playing and seeks the selected program to play the program. The LIA has eight subcode channels: P, Q, R, S, T, U, V, and W. The table of contents uses the Q channel and displays the song numbers and indexes of up to 99 programs, up to one-hundred 99. CD-G adds a graphic function that displays karaoke lyrics and song images using R-W subcode 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 audio data blocks consisting of 98 frames, which are data processing units of CD-DA, in sector units. 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, since CD-ROM must use a specific host computer, compatibility between systems is inevitably required and is limited to spread in each home. In order to make up for the shortcomings of the CD-ROM, the CD-I is equipped with a computer, a character reproducing circuit, an image reproducing circuit, an audio reproducing circuit, and a computer data reproducing circuit. It is solved. In other words, the CD-I system may be referred to as a computer dedicated to regeneration by replacing a hard disk or a floppy disk 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 application programs are inevitably required. This has the drawback of raising the cost. In addition, it is inconvenient that a computer cannot directly access a data location stored on a disk, but must access it through an OS or an application program. U.S. Patent 5,243,582 discloses a reproducing apparatus for a karaoke compact 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.

An object of the present invention is to provide a voice service corresponding to the operation while playing thousands of song accompaniment with a high-quality background that fits the music atmosphere in one compact disc to solve the problems of the prior art as described above A compact disc video song accompaniment player is provided.

The apparatus of the present invention for achieving the above object is a CD playback means; A command input unit; A display unit; A digital decoder configured to input digital data output to the CD player to generate an accompaniment signal of the selected music and a background image signal composed of a plurality of still images suitable for the song lyrics of the music; An audio selector which selects an audio signal of the CD playback unit or an audio signal of the CD decoder and outputs the audio signal to an audio output terminal; A video selector for selectively outputting a background image signal of the CD-OQ decoder to a video output terminal; And display an operation state on the display unit and control a CD playback unit to read the selected data from the disc according to the command of the command input unit and the address information from the CD decoder. And control means for controlling the signal selection of the controller and controlling the voice message to be output through the audio selector in response to the system operation.

Therefore, in the present invention, a single compact disc can be used to display thousands of music and a plurality of still images suitable for each music as a background image, and can provide a voice service in response to a system operation. 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 the 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, and W of 98 frames consists of 96 bits except for the first 2 bits of sync bit (12). . 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, an 24-bit address (minutes, seconds, and frames) 22, an 8-bit interval bit (24), and 24f bits. Is composed of pointer addresses (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 0 decimal. 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 Alh, 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 Alh 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. An area 36, a third table area 39, a first data area 38, a second data area 40, and a third data area 41 are included.

Information for displaying an image group in which groups of background images having similar images are grouped together, etc., and 00h denotes the beginning of an image group, and 01h denotes 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.
