It waits for an interrupt from 29, 32, or 34, determines the contents of the interrupt processing in response to the interrupt, and performs data transfer, data conversion, and data operation with each peripheral device. For example, when the remote control receiving unit receives the request, the remote control interface 23 informs the microprocessor 20 of the occurrence and the content of the remote control operation.
Inform Then, the connection is made to the transmission line via the line connection interface 24, and the request content is transmitted to the center via the modem interface 21. When data corresponding to the request is sent from the center, if it is image information, it is written to a write address designated by the memory control 29 in the image memory 28. If the information is music information, the sound generation unit 1 is output via the music generation interface 34.
Send to 5. The procedure of these processes can be designed by a well-known program control by a microcomputer.

The display control 27 is controlled by the microprocessor 20
In accordance with the instruction, the display signal synthesizer 30 is controlled to output a display signal while reading out the image information written in the image memory 28. As the display signal, the title, number, etc. of the song requested to the television 12 are displayed. In addition,
The display control 27 and the display signal synthesizer 30 can be regarded as an image information processing device.

The sound generator 15 includes a microprocessor 33,
It comprises read / write memories (RAM) 35, 38, read memories (ROM) 36, 37, a bus switch 39, a tone synthesizer 40, and a DA converter 41 . Microprocessor 3

5 and the RAM 38 can be regarded as a performance memory.

As performance information, corresponding to a double tone performance,
For a plurality of parts i = 1 to n, sound source numbers g1 to gn,
These sound source parameters {p1} to {pn}, pair data of pitch and pitch, {P, L} 1 to {P,
Expression data such as L｝ n, tempo data, transposition data, repetition symbol data, crescendo, decrescendo, and the like can be considered. Not all of these are required,
The more data, the richer the expression. If some data is omitted, the abbreviated information is sent, and in that case, a predetermined data value can be used instead. For example, among the sound source parameters that are not transmitted, the parameters stored in the ROM 37 can be substituted.

As the processing of the performance information, it is possible to prohibit the performance of the designated part and perform a so-called minus one performance or perform the performance for each part.

As the tone synthesizer 40, a tone synthesizer having a plurality of channels, capable of generating multiple tones, and capable of generating different tone colors, respectively, is used. Descriptions of these synthesizers are omitted because they are known.

In the above description, the adapter 11 and the sound generator 15 are connected, but they may be used separately. For example, first, the microprocessor 20 connects the adapter 11 and the memory 17 and temporarily stores and stores music information and image information in the floppy disk memory. The microprocessor 20 and the memory 17 can be regarded as a transmission processing device and a storage memory, respectively. Next, the microprocessor 20 may transfer the music information from the floppy disk memory to the RAMs 35 and 38 and, at the same time, transfer the image information to the image memory 28 by connecting the sound generator 15 and the memory 17. The microprocessor 20 can be regarded as a storage memory reading device. In this way, the floppy disk storing the music information and the image information of the music desired to be played is mounted on the memory 17, and the music information is transferred from the floppy disk to the RAMs 35 and 38, and at the same time, the image information is stored in the image. Each time the data is transferred to the memory 28, the same music is played and displayed as an image. Also, music information and image information for a plurality of music pieces transmitted via a transmission line may be stored on a floppy disk. In this case, the floppy disk, that is, the storage memory is stored in the image / music file memory 9 of the center 1.
The music information and the image information of the music desired to be played are read out from the floppy disk in accordance with the request inputted from the remote controller 14, respectively.
5, 38, and may be written to the image memory 28.

With the above operation, the music information and the image information are supplied to the tone synthesizer 40 from the performance information processing device including the microprocessor 33 and the like, that is, even when the performance is being performed, the microprocessor The music information and the image information from the image music file 9 are received by the memory 20 and the memory 17.

The sound generator 15 may be provided with a keyboard so that it can be played in real time. In this case, the surplus part of the plurality of parts is used for manual performance.

A semiconductor memory may be used instead of the floppy disk memory. The sound source parameters vary depending on the tone synthesis method. In the subtraction method, the transfer characteristic of the filter and the sound source waveform may be sent. In linear predictive coding (LPC) used for speech synthesis, the residual waveform and prediction coefficient, in sine wave synthesis, the spectrum level and phase angle data of each harmonic component, and in waveform synthesis, the sample value of each waveform and , The combined weight coefficient of the waveform, the frequency of the modulated wave and the modulated wave,
The level and the phase angle are the sound source parameters, respectively.

The sound source parameters are usually closely related to the synthesis method of the tone synthesizer 40. However, it is possible to change that parameter to a parameter of a type suitable for another synthesis method. Therefore, the tone synthesizer 4
When a parameter that is not in a format that matches the synthesis method of 0 is sent, conversion may be performed. This conversion can also be performed by the microprocessor 33 and a conversion procedure program.

Note that a receiving device may be provided in place of the above-mentioned line connection device to receive transmitted music information and perform. For example, in the above description, a request for a desired music has been described. However, when the so-called BGM (background music) is designated by the same operation as above, the music information of the predetermined music transmitted from the center 1 is obtained. The image information is received by the user terminal device 6 via the line connection device 10, so that music can be enjoyed.

Further, the image and music file 9 of the center 1 and the terminal device 6 do not necessarily have to be physically far from each other, but need only be connectable via a transmission line. The music information and image information stored in the memory 17 are stored in the center 1
The file management can be performed in the same manner as the image music file memory 9.

Further, the frequency of requests to the center can be reduced. The removable storage memory can be removed from the music performance device and carried, and used in another music performance device.

Also, music is prepared in the image music file memory as music information and is used after transmission, so that the image music file memory, the storage memory, and the sound are stored.
The memory capacity of the source parameter memory and the performance data memory can be reduced.

Also, since the music is sent in a format substantially equivalent to the score, it is possible to partially change the music. For example, the tempo, pitch, and part of the part can be changed, and these can also be used for music training and education. Further, since the sound source parameters are transmitted, a sound source that matches the music can be used, and transmission and reproduction of music that matches the atmosphere of the program can be performed.
