PROBLEM TO BE SOLVED: To provide a means capable of correctly performing communications between respective 1394 networks even when the node ID of each information device is changed and a topology configuration is changed by bus-resetting in a certain 1394 network in a network wherein a plurality of IEEE 1394 (hereinafter called 1394) networks exist and the respective 1394 networks are connected by a network other than the 1394 networks. SOLUTION: Communication between the respective 1394 networks n is performed through communication terminals 20. The communication terminal 20is has a function of emulating an AV (audio and visual) device 10os on a second network nos. In addition, each communication terminal 20 always and virtually realizes a topology configuration of a different network n with the newest information by sensing a change in the node ID of each AV device 10is and a change in a topology configuration in a self-network nis and notifying a communication terminal 20os of the second network nos of the changes.
