<p>To make it possible to transmit a transmission packet which always includes correct information for identifying a transmission end. In a bridge portal 103b, a transmission packet, which is transmitted from a 13940HCI section 124b to a Link section 125b, is made to include transmission end information for indicating whether the transmission end of the transmission packet is a self-node, or the transmission end thereof is another node residing in another bus. When an asynchronous data packet is produced in the Link section 125b based on the transmission packet, if another node is a transmission end, the node ID of another node included in the transmission packet is used as a source ID. Contrarily, if the self-node is a transmission end, the node ID of the self-node is used. In this manner, it becomes possible to transmit an asynchronous data packet which always include the node ID of the correct transmission end to the 1394-bus 102 (Bus #2). <IMAGE></p> |
