Abstract
A bus reset method in a network connected by the IEEE 1394 bus is provided. The bus reset method in a network in which a plurality of apparatuses are connected by the IEEE 1394 bus includes the steps of (a) sensing the state change of a port, (b) confirming whether loops exist in the bus when it is sensed in step (a) that a new apparatus is connected to an apparatus of the network, (c) transmitting the bus configuration information of a slave node from the slave node to a master node when it is confirmed that loops do not exist in the step (b), (d) re-configuring the bus of the network from the transmitted bus configuration information and the existing bus configuration information of the master node, and (e) broadcasting the re-configured bus configuration information to all apparatuses connected to the network.
