Abstract:
A method for extending channels of the IEEE 1394 serial bus in a channel assignment through an isochronous resource manager (IRM) of an IEEE 1394 node, wherein the IEEE 1394 node comprises a CP register for physical channels and a CE register for extended channels which have the same format as the format of a CA register which holds information on channels assigned by the IRM, comprising:checking whether all the channels of the IRM are used and there is available bandwidth; setting a CE register value, which is a value obtained by adding 64 to a CP value of the CP register, to the CE register when all the channels are used and there is available bandwidth; and generating a packet by setting a tag field value of a packet as a predetermined value when the CE register value is set to the CE register.
