Abstract
A method of simple network synchronization in a bus extension system with expanded capabilities wherein a plurality of independently-operable multimedia multiplexing devices are connected to the same network in parallel. The method of network synchronization for multiplexing devices connected by parallel through an extension bus is provided wherein one of two or more multiplexing devices is used as a clock master and other remaining multiplexing devices as slave devices and wherein the multiplexing device acting as the clock master is operated in synchronization with a clock received from a network while the multiplexing devices acting as the slave devices receive a clock from a clock transmission line of the extension bus which is outputted after the clock master has established synchronization with the network clock and regenerate a clock leading the received clock in phase.
