<P>PROBLEM TO BE SOLVED: To provide a network system transmitting a timing of a word clock with sufficient stability through a transmission route same as that for audio signals. <P>SOLUTION: In forming an audio network system in which a plurality of processors each having two sets of transmission I/Fs and reception I/Fs are connected in the form of a loop and a TL frame generated by a master node and including a plurality of storage regions for audio signals circulates along two looped transmission routes formed between the processors in different directions in each constant period to transport the audio signals among processors, the system is configured such that the master node measures time Dfw from transmission of a sound transmission frame to the return of the frame to the master node, and writes the time Dfw in the sound transmission frame, and each of other node generates a word clock for signal processing, based on the time, receiving times Tr1 and Tr2 of TL frames of the same period which circulate through two transmission routes, and a predetermined target time Tt. <P>COPYRIGHT: (C)2010,JPO&INPIT |
