Data transmission system and method

摘要

The data transmission method employs IEEE P1394 protocol. The data header of the transmitted isochronous packet is added with a node identifier identifying the transmitter node, so that the receiver node can immediately identify the transmitter node, and can thereby request the transmitter node to maintain transmission. A Broadcast channel is a default channel used for isochronous packet transmission, unless a different channel number is otherwise specified. Thus, it is not necessary for the user to coordinate the channel number used by the transmitting and receiver nodes. It is also not necessary for the transmitter node to notify the receiver node, or the receiver node to notify the transmitter node, of the channel number used.
