Abstract

A plurality of devices connected to a network each includes at least either one or more output plugs for transmitting one or more data streams, or one or more input plugs for receiving one or more data streams, and each of the devices is capable of packeting a plurality of data streams and isochronously transferring the packet to another device in the network. Connection setting program, designed to set connection between a transmission source device and a transmission destination device in the network, includes a step of detecting a predetermined condition for performing automatic setting of logical connection, and a setting step of, in response to detection of the predetermined condition, automatically setting logical connection between the one or more input plugs and the one or more output plugs of the devices. Such arrangements facilitate setting of logical connection between the devices interconnected via the network.

Claims

1. A connection setting program containing a group of instructions for causing a computer to perform processing for setting connection between a transmission source device and a transmission destination device in a music system, said music system comprising a plurality of devices connected to a network, each of said devices in said network being capable of organizing a plurality of data streams into a packet and isochronously transferring the packet to another device in said network, each of said plurality of devices including at least either one or more output plugs for transmitting one or more data streams, or one or more input plugs for receiving one or more data streams,

said connection setting program comprising:

a step of detecting a predetermined condition for performing automatic setting of logical connection; and

a setting step of, in response to detection of the predetermined condition, automatically setting logical connection between the one or more input plugs and the one or more output plugs included respectively in said plurality of devices.

2. A connection setting program as claimed in claim 1 wherein said predetermined condition is when software containing at least said connection setting program is installed in any one of said plurality of devices.

3. A connection setting program as claimed in claim 1 wherein said predetermined condition is when a bus reset has occurred in said network, when another device has been newly connected to said network, or when device-connecting driver software is started up in response to powering-on.

4. A connection setting program as claimed in claim 1 wherein said data stream is a stream of waveform data, and the waveform data are synchronized in sampling frequency between said plurality of devices, and wherein said predetermined condition is when the synchronized sampling frequency is to be changed.

5. A connection setting program as claimed in claim 1 wherein said music system includes a memory for storing the logical connection between said devices set by said setting step, and wherein said setting step automatically sets the logical connection on condition that no logical connection between said devices is currently stored in said memory.

6. A connection setting program as claimed in claim 1 wherein said music system includes a detector for detecting a type of each of said devices connected to said network, and wherein said setting step automatically sets the logical connection in response to a result of detection by said detector.

7. A connection setting method for causing a computer to perform processing for setting connection between a transmission source device and a transmission destination device in a music system, said music system comprising a plurality of devices connected to a network, each of said devices in said network being capable of organizing a plurality of data streams into a packet and isochronously transferring the packet to another device in said network, each of said plurality of devices including at least either one or more output plugs for transmitting one or more data streams, or one or more input plugs for receiving one or more data streams,

said connection setting method comprising:

a step of detecting a predetermined condition for performing automatic setting of logical connection; and

a setting step of, in response to detection of the predetermined condition, automatically setting logical connection between the one or more input plugs and the one or more output plugs included respectively in said plurality of devices.

8. A connection setting apparatus for setting connection between a transmission source device and a transmission destination device in a music system, said music system comprising a plurality of devices connected to a network, each of said devices in said network being capable of organizing a plurality of data streams into a packet and isochronously transferring the packet to another device in said network, each of said plurality of devices including at least either one or more output plugs for transmitting one or more data streams, or one or more input plugs for receiving one or more data streams,

said connection setting apparatus comprising:

a detection section that detects a predetermined condition for performing automatic setting of logical connection; and

a setting section that, in response to detection of the predetermined condition, automatically setting logical connection between the one or more input plugs and the one or more output plugs included respectively in said plurality of devices.
