Title:
DATA TRANSMITTING METHOD
Document Type and Number:
Japanese Patent JP3152233
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To contrive effective data transmission by simplifying procedures for transmission and reception between nodes by outputting an output instruction to an other node after a channel number and a band to be used are acquired by the side of a node to request the output of data to the other node.
SOLUTION: When synchronous communication data are transmitted by using a P1394 protocol of the IEEE, a channel number and a band are acquired by instructing an interface block 201 by using a node CFM to manage communication and asynchronous communication by an instruction of a user of the node A on the side to request the output by a control block 203. When the acquisition is confirmed, the output instruction is transmitted to a node B so as to output it with the acquired channel number by using the asynchronous communication via the interface 201. Synchronous communication data are outputted by using the designated channel according to the output instruction by the node B and transfer of communication between the node A and a CFM to acquire the channel and the band is eliminated by the node on the output side.
