In the sixth step S6, the fact that the front panel 32 of the disc storage unit 19 has been opened is transmitted to the commander 5 (or the operation unit 1) via the transmission / reception device 37 by setting a status flag or the like.

When the commander 5 receives the status flag as shown in the seventh step S7, the commander 5 judges that a new disc has been accommodated or removed in the disc accommodating portion 19 and starts reading the genre code.

FIG. 4 is a flowchart for rewriting on the commander 5 side. When the commander status flag is received in the first step ST1 (S7), initialization for rewriting is started.

That is, as shown in the second step ST2, EE
-Clear the genre code recording areas of a plurality of discs stored in the PROM 39 or 41.

Next, as shown in the third step ST3, the disks 18, for example BGV, arranged in parallel in the disk storage portion 19 are provided.
Read the genre code recorded on the CD for (background video).

In the next fourth step ST4, the genre code is written in the EE-PROM 41 or / and 39 to reach the end.

Although reading and rewriting of the genre code have been described in each of the above-mentioned flowcharts, the track information such as the number of added or removed discs detected by the movement of the sensor 28 of the disc housing portion 19 is also read and rewritten. Writing is done.

Embodiments The contents of various discs housed in the autochanger as the karaoke apparatus of the present invention and the disc arranging method will be described in detail below with reference to FIGS. 5 to 13.

First, a method of arranging the disks will be described with reference to FIG. 5 which is a view of the disk storage portion 19 of the autochanger 4 shown in FIG.

The disk storage unit 19 has a total of 100
CDs can be placed side by side. The types of CDs arranged in parallel are four types of CDs indicated by "A" to "D", and these "A" to "D" CDs will be described below.

The "A" CD is a CD in which only MIDI (general music) data is recorded, and is a CD containing only MIDI data.
It is a ROM disc that does not contain video CD images.

The "B" CD is a CD on which MIDI (management music) data is recorded, and contains the image of the video CD in addition to the MIDI data. The video on this video CD is BG
Used as V.

"C" CD is a BGV video CD,
Video of BGV used for backing during karaoke performance is recorded, and MPEG (Moving Picture Image Coding Expe
rtsGroup) Only video is used without audio data. This BGV video CD consists of the following two types. BGV disc for 256 genres BGV disc with subdivided video types up to 256. BGV disc for a specific genre (optional) A BGV disc that has 255 types of series in the video and 256 video genres are set for each series. This allows more detailed video designation. This disc is optional and is purchased per user.

"D" CD is BGM (Background
It is a CD / DA for music), a video CD disc, and a BGM disc played between karaoke songs. It is assumed that the BGM video CD does not contain a file with the extension "TXT", and the disc containing the file with the extension "TXT" is used as a BGV video CD.

The CDs defined by the above "A" to "D" are arranged side by side in the disc storage portion 19 as shown in FIG. That is, 1 to 5 "B" CDs are sequentially arranged in parallel from the front panel 32 side. This "B" CD is fixed to five.

Next, a maximum of 10 "A" CDs, from the 6th to the 15th, are arranged in parallel. The "A" CD will be released when MIDI data is full on the hard disk of the communication karaoke controller, so one by one will be added and not 10 from the beginning.
"C" CDs to be placed next to each other from the 6th to the 15th
Do not put in.

"C" CD [FMV which is a CD for BGV
(Frequency Modulation Video) decoder is built into the autochanger 4], and MIDI data is not inserted, and the 16th sheet is sequentially set and set.

The "D" CD, which is a CD for BGM, is set in order from the last 100th disc in the disc storage unit 19 to the front (front panel 32) side.

Of the CDs indicated by "A" to "D", two types of 2 indicated by "C" CD which is a BGV video CD.
In the 56-genre BGV disc and the optional specific-genre BGV disc, a text file containing a code called a genre code indicating the type of video is recorded on the disc.

Also, since 10 images are contained in the "B" CD for MIDI (management music), this image is a BGV up to the 10th genre.

The above-mentioned genre code is represented as follows by the series number which takes a value from 0 to 255 and the genre number.

Mmm-nnn mmm: series number (0 to 255) The series number "0" indicates a code of a 256-genre BGV disc. nnn: Genre number (0 to 255)

The genre code expression for each disc described above is shown below.

Video CD (10 genres) contained in "B" CD in which MIDI (managed music) data is recorded The number obtained by adding 2 to the genre code sent from the karaoke controller 2 is the disc track number.
No need to read genre code file.

BGV disc for 256 genres The series number of the genre code is fixed to "0". 0-nnn nnn: Genre number (0 to 255) Example: 0-250,0-3

BGV disc for specific genre (optional) The genre code series numbers "1 to 255" and "0" are not used. mmm-nnn mmm: Series number (1-255) nnn: Genre number (0-255) Example: 8-34, 145-32

Next, the directory and genre code file format will be described. (a) Directory A BGV video CD (“C” CD) contains two genre code files indicating genre codes of songs. All information such as the type of disc is put in the genre code file so that the genre code can be set only by reading the genre code file. VCDBGV00. TXT Genre code only for this BGV disc. VCDBGV01. TXT All genre codes of BGV discs released in packages including this disc. For example, in the case of a package consisting of 5 discs, the VCDBGV01. Insert TXT. If you sell one, enter the genre code for one of the discs (the contents of the file will be the same as VCDBGV00.TXT). VCDBGV02. TXT A file containing change data for the genre code that has already been set. 3 files are disk (“BGV” directory)
Put in. FIG. 6 shows an example.

(B) File Format In the "C" CD of the BGV video, three text files containing the genre codes of the songs shown in "(a) Directory" are put. All the information such as the type of disc is put in the genre code file, and the genre code can be set only by reading the genre code file.

Next, a setting method for setting the plurality of CDs shown in "A" to "D" in the disc storage portion 19 will be described. As the disc, there are a disc sold in a package and a disc sold in one package. In the case of a package disc, when the serial numbers for the number of discs are printed on the discs and the discs are arranged side by side in the disc accommodating portion 19, the discs from the front panel side Arrange them in numerical order. For example 5 sheets 1
1 to 5 for packaged discs in set
The numbers are printed so that the discs are arranged in order from the first from the front panel 32 side of the disc storage portion 19. In the case of a single disc sold, it is arranged so that it does not fit between a plurality of discs of a set sold as a package.

In FIG. 10, as a BGV video CD which is a "C" CD, one disc is sold in the disc storage portion 19 (plan view), nine discs, ten discs, one package, eight disc packages, one package and five discs. The structure in which one set of packages is arranged in parallel is shown.

The genre code set in the disc storage unit 19 as described above is read as shown in FIGS. 3 and 4, but the BGV C in the third step ST3 of FIG. 4 is read.
The reading of the genre code of D does not read the genre code one by one from all the discs in order to shorten the reading time. T
The genre code is read by reading the data of the XT file.

Here, as an example, "A" shown in FIG.
The reading of the genre code when the "D" disc is set in the disc storage portion 19 will be described. FIG.
In the case of 0, an example in which one disc sold is arranged separately is shown, but it is obvious that the discs may be collected and set in one place.

In FIG. 10, the genre code initialization is started.
After clearing the genre code of the EE-PROM 41 or / and 39, the VCDBGV of the 16th disc
01. Read TXT file. The 16th disc VCDBGV01. The TXT file contains the genre codes of 10 discs. By writing this data in the EE-PROM, the genre codes for 10 sheets can be read at one time.

VCDBGV02. If the TXT file is included, VCDBGV01. After reading the TXT file and setting the genre code data in the EE-PROM, the EE-PROM is searched again and the VCB
GV02. Correct the genre code that has a modification instruction in the TXT file.

From now on, the genre code is EE-PROM.
All operations to write to a. VCDBGV01. Read TXT file, E
Write to E-PROM b. VCDBGV02. The TXT file is read, and the data already written in the EE-PROM is corrected. In the description, the description of the above item b is omitted,
VCDBGV01. V after reading TXT file
CDBGV02. Performs TXT file search and read operations.

Next to the 16th disc, the V of the 25th disc
CDBGV00. Read TXT file. Genre code file (VCD
BGV01. The disk is set according to the TXT file) or VCDBGV0 of the 25th disk
0. Check the disk number of the TXT file. If the disc numbers are correct, it is determined that the discs are set in the specified order, and the subsequent operation is continued.

If the disc numbers are different, it is judged that the discs are not set in the specified order, and 17
From the first disc, one by one VCDBGV01. TXT
Read the file and set the genre code correctly.

If it is determined that the 10-package disc is set as specified, the 25th disc, then the 26th disc VCDBGV01. Read TXT file. This disc is a disc sold for one, so it is VCDBGV01. TXT contains only one genre code for one disc. Therefore, only one genre code can be written in the EE-PROM. The 4th disc from the 26th disc to the 29th disc is a disc that is sold as one disc, so one disc from one disc to VCDBGV01. Read the TXT file and record it in the EE-PROM.

The 30th disc of VCDBGV01.
Since the TXT file contains genre codes for eight discs in the same manner as, the genre codes for eight discs are recorded once in the EE-PROM.

Next to the 30th disc, the V of the 38th disc
CDBGV01. Read TXT file. This file also contains the genre codes for 5 discs, so the genre codes for 5 discs can be EE-PRO at once.
Record in M.

Next to the 38th disc, the V of the 43rd disc
CDBGV01. Read TXT file. This disc is a disc sold for one, so it is VCDBGV01.
TXT contains only one genre code for one disc. Therefore, only one genre code is EE-PR
Cannot write to OM. The 5th disc from the 43rd disc to the 48th disc is a disc sold for 1 disc, so 1 disc from 1 disc to V disc
CDBGV01. Read TXT file and EE-PR
Record in OM.

From the 49th disc to VCDBGV0
1. An attempt is made to read the TXT file, but since there is no disc, it is determined that the area of the BGV video CD has ended, and the reading of the genre code ends.

Next, a case where a new music disc is added to the disc storage portion 19 will be described with reference to FIG. When adding a new music disc, the switch 36 must be pressed to open the front panel 32, but the C in the system controller 25 or the karaoke controller 2 must be pressed.
The PU writes the operating state of the switch 36 into the EE-PROM 39 or / and 41, and further checks the contents of the EE-PROM 39 or / and 41 when the karaoke apparatus 12 is powered on, and the switch 36 is pressed before the power is turned off. Check if it was done.

The front panel 32 is opened and the switch 3
If 6 is pressed, the CPU of the system controller 25 informs the commander 5 that the switch 36 has been pressed according to the command status of the karaoke commander.
When the commander 5 receives the status that the switch 36 is pressed, the commander 5 determines that a new score has been added, and reads the new score genre code.

When the commander 5 starts reading the new music genre code, it automatically starts reading the genre code from the disk next to the disk previously read. To reduce the read time, instead of reading the genre code from all the added discs, the V
CDBGV01. The genre code is read by reading the data of the TXT file.

Here, as an example, in the disk arrangement of FIG. 10, a case of adding one set of three package disks and two sold disks to the disk storage portion 19 will be described with reference to FIGS. 11 and 12. To do.

Of course, when the above-mentioned package selling discs are added to the disc accommodating portion 19, they are arranged in parallel in the designated disc order (the number order printed on the discs).

When loading the new music genre code,
The karaoke commander starts from VCDBGV01. TXT
Read the file. In this example, as shown in FIG. 11, the 48th disc is the one in which the genre code is read last,
49th VCDBGV01. Read TXT file. The 49th disc VCDBGV01. TXT
As shown in FIG. 12, the file contains genre codes of three discs. By writing this data in the EE-PROM, the genre codes for three sheets can be read at one time.

VCDBGV02. If the TXT file is included, VCDBGV01. After reading the TXT file and setting the genre code data in the EE-PROM, the EE-PROM is searched again and the VCDB is searched.
GV02. Correct the genre code that has a modification instruction in the TXT file.

The genre code is now EE-PROM
All operations to write to a. VCDBGV01. Read TXT file and EE
-Write to PROM b. VCDBGV02. The TXT file is read and the data already written in the EE-PROM is modified in the order of modification. In the description, item b is omitted, but VCD
BGV01. VCDB after reading TXT file
GV02. Performs TXT file search and read operations.

Next to the 49th disc, the V of the 51st disc
CDBGV00. Read TXT file. Genre code file (V
CDBGV01. The disk is set according to the TXT file) or the 51st disk is VCDBGV
00. Check the disk number of the TXT file.
If the disc numbers are correct, it is determined that the discs are set in the specified order, and the subsequent operation is continued. If the disc numbers are different, it is determined that the discs are not set in the specified order, and one by one from the 50th disc VCDBGV01. Read the TXT file and set the genre code.

If it is determined that the 51st disc has been set as specified, the 51st disc is followed by the 52nd disc VCDBGV01. Read TXT file. This disc is a single disc, so VC
DBGV01. TXT contains only one genre code for one disc. Therefore, only one genre code can be written in the EE-PROM. 52,
The 2nd disc of the 53rd disc is a disc sold for one, so from 1 disc to VCDBGV01. Read the TXT file and record it in the EE-PROM.

From the 54th disc, VCDBGV0
1. An attempt is made to read the TXT file, but since there is no disc, it is determined that the area of the BGV video CD has ended, and the reading of the genre code ends. When the new music is added and the BGV video CD area and the BGM CD area are stuck together as shown in FIG. 13,
In the karaoke commander, the disc from which the genre code is being read is a CD / DA disc genre code text file (VCDBGV0
1. If the video CD disc does not include TXT), it is determined that the area of the BGV video CD has ended.

In the above embodiment, the case where a new disc is added has been described. However, when a predetermined disc becomes unnecessary from the disc storage portion 19 and the predetermined disc 18 is removed, as shown in FIG. From the sensor 28, the removed disk 18 position data and the genre code data for correcting the same are given to the system controller 25 through the disk position detection circuit 29, so that the above-mentioned VCDBGV
02. Since the work of rewriting the TXT file is being performed, the genre code of the disc removed from the disc storage unit 19 is naturally understood.

[0094]

As is apparent from the above description, the commander automatically informs the commander that a disc has been added or removed, so that the commander can automatically detect the BGV from the disc to which the CD autochanger has been added.
By reading the code file, the position of the newly added or removed disc and the BGV code information of each image can be obtained. In addition, when the BGV code is inserted into the BGV disc, it is possible to shorten the read time of the BGV code from the disc by inserting several pieces of data.
