FIG. 1 is a block diagram of a data processing apparatus according to an embodiment of the present invention. The data processing device 1 includes switching devices 2 corresponding to the number of connected control devices 4 and merging devices 3 corresponding to the number of controlled devices 5 to be connected. Exchange device 2 and control device, and merge device 3
And the controlled device 5 are connected in a one-to-one correspondence.

The configuration shown in FIG. 1 assumes a state mainly used for a large-scale karaoke system.
In addition to a performance data reproducing device that outputs karaoke performance data, an input device such as a percussion operated by a singer, a gesture detection device that detects a singer's gesture, and the like are connected. As the controlled device 5, an electronic musical instrument, a display control device, a lighting control device, and the like are connected. The electronic musical instrument generates a karaoke performance sound according to the input performance data. The display control device edits a character pattern such as lyrics and displays it on a monitor. The lighting control device controls the brightness and color of the lighting according to the performance state such as the volume.

The transmission of data from the control device 4 to the switching device 2 is performed in a MIDI format. The switching device 2 transfers the MIDI data received from the control device 4 to a predetermined merge device 3. As described above, since the merge device 3 is connected to the controlled device 5 in one-to-one correspondence, the transfer to the merge device 3 has the same meaning as the transfer to the controlled device 5. The controlled device 5 of the transfer destination is determined by an exchange table (see FIG. 3) stored in each exchange device 2. The merge device 3 receives data from the plurality of switching devices 2, that is, the control device 4, combines the data so as not to collide, and outputs the combined data to the controlled device 5. As described above, the controlled device 5 has an active function such as an electronic musical instrument or a lighting control device, and controls its own operation in accordance with the input data.

Here, the exchange device 2 can transfer the MIDI data input by setting the exchange table to any merge device 3. Further, the input MIDI data can be transferred in the same format, and the MIDI data can be converted into data of another format and transmitted. That is, the controlled device 5
If the device has a function of receiving and decoding MIDI data and executing a corresponding operation, the device directly transfers the MIDI data. After converting to the data of this, this is transmitted. Even if the device does not have a function of receiving MIDI data, if the device has a function of receiving data in another format, the device converts the format to that format and transmits the data. In the case of a non-intelligent device, control data used in the device is generated to directly control the device.

FIG. 2 is a block diagram of the switching device 2. The control unit 10 including a microcomputer has a memory 11
In addition, an input interface 12 and an output interface 13 are connected. In the memory 11, in addition to the exchange table shown in FIG. 3, a buffer area for buffering data input from the input interface 12 is set. The input interface 12 has a 5-pin DIN connector and a UART, and converts serial data input from the control device into parallel data and inputs the parallel data to the control device 10. The control device 10 receives the type of MIDI data (note on / off, data,
The exchange table is searched using the program change data, system exclusive data, etc.) as search keys.
In addition to determining the transfer destination of the data, the device determines whether the transfer destination device can receive the MIDI data, that is, determines whether the data needs to be rewritten. When rewriting is necessary, how the rewriting should be performed is also stored in the exchange table, so after rewriting according to the method, the data is transferred to the device. Data to be transmitted is input to the multiplexer 14 via the output side interface 13. The multiplexer 14 is used for all the merging devices 3
And one of them is connected to the output side interface 13 by the select signal.

The communication between the switching device 2 and the merging device 3 may be of any type as long as both the devices can process. In this embodiment, transmission and reception are performed in the MIDI format in principle (except when the controlled device 5 is directly controlled by control data).

FIG. 3 is a diagram showing an example of the exchange table.
In the exchange table, the type of the input MIDI data and the transfer destination of the data are stored in correspondence with each other, and whether or not the data needs to be rewritten at the time of the transfer and how to rewrite the data if necessary Is described. In the example of FIG. 7, if the data is other than the system exclusive data, the transfer destination is determined according to the designated MIDI channel. In that case, the data does not need to be rewritten. In the case of system exclusive data, the transfer destination of the data is determined by the device number included in the data, and it is necessary to rewrite the data depending on the transfer destination. The contents of the exchange table are stored in the control device 4 connected to the exchange device 2.
Is transmitted as MIDI exclusive system exclusive data.

The controlled device 5 to which the MIDI data is directly transferred from the switching device 2 via the merge device 3 has a function of decoding and receiving the MIDI data. (OMNI) may be set, or only the data of the channel number selected by the switching device 2 may be set to be received.

FIG. 4 is a flowchart showing the operation of the switching device. The control unit 10 of the switching device executes various operations to maintain the operation of the device, but this flowchart shows only the data reception / transfer operation. First,
It is monitored whether MIDI data is input from the input interface 12 (n1). If there is no input, execute another operation. If there is an input, this data is received and buffered (n2). When the reception of the MIDI data is completed, the head of the data is read out and the type of the data is analyzed (n3). If this data is table data (n4), the contents are written in the exchange table set in its own memory 11 (n10). The table data is described in the format of system exclusive data. On the other hand, if it is not table data, the transfer destination of this data is read out (n6) by referring to the exchange table (n5). Further, it is determined whether or not this data needs to be rewritten when the data is transferred to the transfer destination (n7). If the rewriting is not necessary, the contents stored in the buffer are transferred to the read transfer destination as it is (n8). If rewriting is necessary, the contents are rewritten according to the format (n11), and the rewritten data is transmitted to the transfer destination (n12).

In this embodiment, when the controlled device 5 having no MIDI data receiving function is connected, data is rewritten by the exchange device 2, but this is performed by the merge device 3. You may. Since the merging device 3 is connected to the controlled device 5 on a one-to-one basis, it is sufficient to uniformly rewrite the received data into a format that can be received by the controlled device 5, and the exchange device 2 does not need to rewrite the data. The device 3 does not need to determine whether the received data should be rewritten.

When configuring the data processing apparatus of the present invention, the switching apparatus 2 and the merging apparatus 3 are modularized, and assembled in accordance with the number and type of the connected control apparatuses 4 and controlled apparatuses 5. Also, connect many interfaces to high-speed data processing equipment,
The above functions may be realized by software.

In the above embodiment, the data to be received is M
Although the IDI data is used, the data format is not limited to this.

[0021]
