〔Example〕

MIDI standard and MIDI sound source Prior to detailed explanation of the present invention, the first section regarding the MII)I standard and MIDI sound source used in the present invention will be explained.
This will be explained with reference to FIGS. 3, 14, and 15.

M I D I (Mutical ln+t+um
What is en+DigitalInte+face)?
It is a well-defined standard that allows musical instruments such as synthesizers and electronic pianos to be connected and exchange information.

An electronic musical instrument that is equipped with hardware according to the MIDI standard and has a function of transmitting and receiving MIDI control signals, which are musical instrument performance control signals in a format defined to carry music information, is called a MIDI device.

CD (compact disc), CD-V (video)
Subcodes are recorded on discs such as LVD (laser video disc) and tapes such as DAT, which contain CD format digital audio. The subcodes are P, Q,
It consists of R, S, T, U, V, and W channels, of which the P and Q channels are used for the purpose of controlling and displaying the disc player.

On the other hand, the R-W channel is an empty channel called a user's bit, and various applications such as graphics, audio, and images have been studied, and a standard for the graphic format has already been proposed.

An MII) I format signal can also be recorded in this user's bit, and the standard has already been proposed.

In this case, in addition to supplying the audio/video signals played by the disc player to the AV system to view the program recorded on the disc, performance program information is also transmitted to MIDI equipment attached to or beyond the AV system. Various applications are being considered for the construction of immersive AV systems including electronic musical instruments and the creation of educational software.

MIDI equipment converts MIDIID-mat signals sequentially supplied from a disc player into serial signals.
A performance is performed according to a musical instrument performance program formed by IDI signals.

First, the MIDI control signal supplied to the MIDI device is serial data with a transfer rate of 31.25 [Kbaud], and is 1 byte of data with a total of 10 bits, including 8 bits of data and 1 bit each of start bit and stop bit. It consists of

Furthermore, at least one status byte for specifying the type of data to be sent and the MIDI channel, and one or two data bytes guided by the status are combined to form a message that is music information. Therefore, 1 message consists of 1 to 3 bytes,
The transfer requires a transfer time of 320 to 960 [μsec]. A musical instrument performance program is formed by a series of messages.

As an example of such a message, the structure of a note-on message, which is one of the channel voice messages, is shown in FIG.

The note-on message of the status byte, for example, is a command corresponding to the action of pressing a key on a keyboard, and is used in pair with the note-off message, which corresponds to the action of releasing a key on the keyboard. This is shown in FIG.

The note number of data byte 1 is 128, which is assigned to the keyboard centered on "middle C" of an 88-key piano.
Specify one of the stages. The velocity of data byte 2 is used to make a difference in the strength of the sound during boat fishing. A MIDI device that receives a note-on message generates a note of the specified scale at a specified intensity.

Further, upon receiving the note-off message, the MIDI device performs an action of releasing a key on a keyboard, for example.

Therefore, instead of an electronic musical instrument, as shown in FIG.
MIDI control signal S by using IDI sound source module MD, amplifier AM3, and speaker SP5
Any musical tone can be generated by IDI.

2, an interface 93, a display device 94, and R
AM95.

Next, the operation of this MIDI karaoke performance device 110A during performance will be explained.

First, before the performance, as shown in FIG. 11, the distributed OMDOD is loaded into the OMDD 5A for the distribution OMD. In this case, OMDOD has the number of copies (n)
The same data for each minute is memorized. Under the control of the host computer 8, the recorded information content for one copy in the distribution OMDOD 1 is sent to the OMDD 5B for the recording OMD and stored in the storage OMDOD 2. At the same time, under the control of the board computer 8, the recorded information content for one time of the distribution OMDOD is transferred to the OMD for the distribution OMD.
It is erased by irradiation with strong laser light from the optical pickup of D5A. In this way, the stored information content is erased one copy each time it is copied (each time it is distributed), and when it is copied n times, all the recorded information content of the distribution ○MDOD is erased, and it cannot be copied thereafter.

The above operation is not limited to this, and may be as follows. In other words, OMDOD has copy count information (
n) is stored, and under the control of the board computer 8, the OMDOD for distribution.

MDD5B for recording information content or OMD for recording
and stored in the recording OMDOD2. At the same time, under the control of the board computer 8, the distribution OMDOD is provided with copy count information (n-), which is the copy count (n) minus 1.
1) Memorize.

In this way, the copy count information is decremented by 1 for each copy (each time it is distributed), and when it is copied n times, the distribution OMD
The copy count information of OD becomes n=o, and it is no longer possible to copy.

Next, of the MIDI karaoke data, quick reference file I
F is sent to a RAM (not shown) in the host computer 8 when the system is started up.

The user operates the operation unit 15 to search for the quick reference file IF and requests the song he/she wants to sing. In response to the request, the board computer 8 sends data of the corresponding song in the sequential file (note file NF, lyrics file L).
F, PCM file PF) is read from OMDD5,
It is stored in the RAM in the board computer 8. The song data includes a note file NF (including screen selection data) sent to the MIDI ID module 6, a lyrics file LF sent to the superimpose circuit 25, and a PCM file PF sent to the D/A converter 22.

Next, send a command to the LVD player 7 to search for the background image specified in the data in the quick reference file IF, and
Make the VD player 7 play.

The music starts playing as soon as the video appears. The host computer 8 reads the note file data NF from the RAM, converts it into a MIDI signal, and MfD! It is sent to the sound source module 6. The audio signal from Joule 6 on MIDIID is sent to mixer 24. In synchronization with this, PCM file data PF is read out and sent to the D'/A converter 22.

The D/A converter 22 converts the data into an analog audio signal and sends it to the mixer 24. The two signals are mixed and sent to amplifier 41, and sound is output from speakers 43 and 44. The amplifier 41 mixes the audio signal from the microphone 4 with the above signal and outputs the sound from the speakers 43 and 44. The board computer 8 receives audio-related MIDI signals,
In synchronization with outputting the PCM signal, lyrics file data L
F is read out, converted into a character signal, and sent to the superimpose circuit 25. The superimpose circuit 25 superimposes the character signal and the video signal sent from the LVD player 7 and sends it to the singer's display 57. The singer looks at the singer's display 57 and sings into the microphone 4 while checking the lyrics. Also,
A signal generator (not shown) provided in the microphone 4 outputs a key control signal to match the pitch of the singer's voice, and the controller board computer 8 outputs keys for MIDI and PCM signals in accordance with key changes. You can change the key of the sound by changing and sending it.

In this case, if the MIDI karaoke data is configured as shown in FIG. 4(A), the operation section 1 in FIG.
If the switch is not switched to "abbreviated performance" in step 5, the entire song P D 1 will be played as shown in FIG. After reading the jump start status byte 80hKD5 in KD, data search is performed for the jump destination status byte 87hKD8, and data reading is resumed from then on, and as shown in FIG. 4(C), the second interlude part PD5 and It is possible to perform an abbreviated performance using the composition PD of the song in which the third chorus part PD6 is skipped.

Next, the operation of this MIDI karaoke performance device 110A regarding data communication will be explained.

At present, LVD and CD karaoke provide new releases by distributing discs. However, in the MIDI karaoke system, the songs are in the form of data rather than discs, so it is possible to supply them through data communication. The configuration is divided into a data receiving system 11 added to the basic system MIDI karaoke performance device 110A and a data transmitting system 12 on the supply side.

Communication is performed according to a determined communication protocol. The data transmission system 12 is entirely controlled by a center computer 74. The center computer 74 reads the MIDI karaoke data stored in the storage unit 76,
It is sent to the data receiving system 11 through the modem 75 in accordance with the communication protocol described above. The data receiving system 11 side is entirely controlled by a microcomputer 71, receives and receives data through a modem 73, and temporarily stores it in a storage section 72 according to the communication protocol described above.

This allows you to visually tell things you couldn't do with conventional karaoke machines, such as which number the song you reserved will be played, or whether the song you're trying to sing has already been reserved. become.

In the above embodiments, an example of a writable OMD was explained as a karaoke information storage medium, but this does not necessarily have to be writable, and it may be a normal CD, CD-ROM, etc.
It may be a ROM, a semiconductor memory, an IC card, a magnetic memory, a magneto-optical disk, or the like.

Also, in the above embodiment, the status byte at the start of the jump was set to a position that temporally precedes the status byte at the destination, or conversely, the status byte at the start of the jump or the status byte at the destination It may be provided at a later position in time. With this configuration, it is also possible to repeatedly perform repeat or refrain performances. It is also possible to set a plurality of pairs of jump start/jump destination status bytes in one song, so that a part of the song can be arbitrarily skipped during performance. These status bytes can be set externally via the operation unit or board computer.

Furthermore, in the above embodiment, the distribution OMD may be configured to be separated and independent from the karaoke apparatus main body and to supply data through an interface. For recording ○MD is M
To confirm that the OMD is for IDI Karaoke,
The karaoke apparatus main body may be configured to confirm the ID data (identification data). In this way, reliability is further improved.

〔Effect of the invention〕

It is possible to skip the middle of a song without any time lag, and it also has a function to prevent copying of karaoke songs, so it can expand the karaoke function, prevent unauthorized copying, and improve the accuracy of payment collection.
It has advantages such as solving copyright problems. Another advantage is that the karaoke system can be expanded and managed in a healthy manner.
