Audiovisual domestic digital bus heterogeneous network destination node information synchronization having input node second synchronization packet set following first packet and inserting synchronization mark second packet

摘要

The node information synchronization technique has a sub network passing first packets and a base network sending second packets. When there is a determined event, the input node forms a second synchronization packet so that the synchronization corresponds to the useful information of the first packet. A synchronization mark is inserted in the second synchronization packet.
