Abstract:
1. A receiving device connected to an IEEE1394 serial bus comprising: an IEEE1394 digital interface board for transmitting and receiving data via the IEEE1394 serial bus; and a processor for controlling the IEEE1394 digital interface board; wherein the IEEE1394 digital interface board is able to receive data from a sending device connected by point-to-point connection by isochronous transfer; and instead of acquiring resources of a band and a channel for isochronous data transfer every time the IEEE1394 digital interface board receives the data transmitted from the sending device by the isochronous transfer, the processor acquires the resources of the band and the channel for the isochronous data transfer via the IEEE1394 serial bus and the IEEE1394 digital interface board only when a bus reset is caused, and holds the resources until a next bus reset is caused.
