Provided is a clock synchronization method in a heterogeneous network. The method includes the steps of: at a cycle master, transferring a cycle begin packet with a current time to a transmitting-side bridge; at the transmitting-side bridge, synchronizing using the time included in the cycle begin packet and a time to transmit the cycle begin packet, and transmitting the cycle begin packet with a first synchronization time to a wireless 1394 coordinator; at the wireless 1394 coordinator, synchronizing using the first synchronization time and calculating a second synchronization time; at the wireless 1394 coordinator, transmitting the beacon frame with a created information element structure to a receiving side bridge on a wired IEEE 1394 network; at the receiving bridge, synchronizing using the second synchronization time and calculating a third synchronization time; and at the receiving-side bridge, synchronizing the heterogeneous network by transferring the third synchronization time to the receiving node.
