Embodiment Construction

[0040] Embodiments of the present invention will be described below with reference to the drawings.

[0041] FIG. 1 shows a detailed structure of a node device 100 such as a mixing engine and a console 130 connected to the device in an audio network system according to an embodiment of the present invention. A node device 100 such as a hybrid engine includes a central processing unit (CPU) 101, a flash memory 102, a random access memory (RAM) 103, a communication input / output interface (COM I / O) 104, a card input / output interface (I / O ) unit 105, signal processor (DSP) 106, local network interface (Net I / O) 107, and bus 109. The connection to the network interface (Net I / O) 108 will be described later.

[0042] The CPU 101 is a processing device that controls the overall operation of the node device 100 . The flash memory 102 is a nonvolatile, rewritable storage device that stores programs to be executed by the CPU 101, various data, and the like. The RAM 103 is a volatile ...

Abstract

The present invention provides audio-frequency network system, wherein, a plurality of partial networks can work independently from each other, and each partial network connects together several nodes including a connection node for transmission of audio signals. A connection network connects respective connection nodes of the respective partial networks so as to connect the plurality of the partial networks with each other through the connection nodes. The connection node of the partial network operates when the audio signal is transmitted from the partial network to the connection network, for forwarding the audio signal from a transmission channel used for carrying the audio signal in the partial network to another transmission channel to be used for carrying the audio signal in the connection network, and operates when the audio signal is transmitted from the connection network to the partial network, for forwarding the audio signal from a transmission channel used for carrying the audio signal in the connection network to another transmission channel to be used for carrying the audio signal in the partial network.
