Abstract:
A communication method for communication system in which a plurality of audio/video equipments are connected via a digital bus capable of transferring synchronous communication packets labeled with channel numbers and asynchronous communication packets in a certain communication cycle, wherein each of said audio/video equipments have virtual output plugs which output said synchronous communication packets or virtual input plugs which input said synchronous communication packets, said method comprising the steps of:controlling said virtual output plugs or said virtual input plugs as registers to which respective addresses are allocated; and connecting one virtual output plug at a transmitting audio/video equipment and one virtual input plug at a receiving audio/video equipment being connected via one channel when said synchronous communication packets are transferred between said audio/video equipments via said digital bus; wherein said registers for said virtual output plug include information indicating state of said virtual output plug whether or not said virtual output plug is capable of transmitting said synchronous communication; and wherein said registers for said virtual input plug include information indicating state of said virtual input plug whether or not said virtual input plug is capable of receiving said synchronous communication.
