Abstract: A bus management node 11 has a register for channels in use REG1 and a bus capacity register REG2. Before starting the synchronous communication, each node 12 transmits a read-out command to the register for channels in use REG1 and the register for channels in use REG1 in order to read out their contents for ascertaining the number of the un-used channel and the residual capacity. If there is any un-used channel and any residual bus capacity, the node 12 transmits write commands to these registers REG1 and REG2 so that the number of the channel to be in use and the capacity of the bus to be in use will be stored in the register for channels in use REG1 and the bus capacity register REG2. This enables bus management to be achieved easily in a system performing synchronous communication between plural nodes connected to the bus.

Abstract: In a communication system, isochronous data can be continuously received without any interruption, and also asynchronous data irregularly transmitted can be received without loss by a signal receiving apparatus. The signal receiving apparatus includes a circuit to receive isochronous data being regularly transmitted and asynchronous data being irregularly transmitted, a common bus for transferring the isochronous data and the asynchronous data thereon, and temporary storage circuit for writing therein the received isochronous data and the received asynchronous data.

Abstract: In a communication system, isochronous data can be continuously received without any interruption, and also asynchronous data irregularly transmitted can be received in a signal receiving apparatus. The signal receiving apparatus is arranged by comprising isochronous data being regularly transmitted; asynchronous data being irregularly transmitted; a common bus for transferring the isochronous data and the asynchronous data thereon; and temporary storage means for writing therein the received isochronous data and the received asynchronous data, respectively.
