Abstract:
1. A network system comprising a series of a plurality of connected nodes, each node having two interface sets of receivers and transmitters, each of the receivers and the transmitters performing communication in a single direction respectively, the plurality of nodes are connected in such a manner that one interface set including a receiver and a transmitter in one node is connected with one interface set including a transmitter and a receiver in a next node, respectively, in the series wherein each one node X in the series which receives a frame from one next node Y via the receiver in one interface set S one of the plurality of nodes operates as a master node which generates and transmits an audio transport frame at a constant period, the audio transport frame circulates along said formed ring transmission route at said constant period, said audio transport frame including a plurality of storage regions for audio signals, and each of said nodes writes audio signals to or reads audio signals from the audio transport frame to thereby transport the audio signals among said nodes connected in series, said master node operates in a single mode and in a twin mode, the master node in the single mode transmits the audio transport frame generated by the master node from the transmitter in one interface set SM said master node comprises:
