Abstract:
1. A network system comprising: a first sub-network system including a first plurality of nodes connected to one another in a cascade style or in a loop style to constitute a first sub-network conveying a plurality of audio signals among said first plurality of nodes; a second sub-network system including a second plurality of nodes connected to one another in a cascade style or in a loop style to constitute a second sub-network conveying a plurality of audio signals among said second plurality of nodes; a first connecting node in said first sub-network system and a second connecting node in said second sub-network system connected to each other to constitute a connecting network conveying a plurality of audio signals, using a plurality of transmission channels, among said first connecting node and said second connecting node; a first controller that controls transmission of the audio signals in said first sub-network system; and a second controller that controls transmission of the audio signals in said second sub-network system, wherein said first controller selects one or more audio signals among audio signals in said first sub-network in said first sub-network system and sets, to said first connecting node, one or more signal names identifying the selected one or more audio signals; wherein, based on the one or more signal names set to said first connecting node, said first connecting node reserves one or more transmission channels among said plurality of transmission channels of said connecting network, sends the one or more audio signals identified by the one or more signal names via said connecting network using the reserved one or more transmission channels, and notifies, to said second connecting node and said second controller, the one or more signal names related with the reserved one or more transmission channels; wherein said second controller selects an audio signal among the one or more audio signals identified by the one or more signal names, notified by said first connecting node, and sets, to said second connecting node, the signal name identifying the selected audio signal; and wherein, based on the signal name set to said second connecting node, said second connecting node receives the audio signal in the transmission channel related with the signal name via said connecting network, and sends the received audio signal via said second sub-network in said second sub-network system.
