A Multi To Multi Streaming Media System's Synchronize

Nowdays transporting audio and video and other multimedia in net by using download with more delay or streaming-transfer. The later avoids that user must wait until the whole file be downloaded completed .The key is streaming-transfer for streaming-media technology. While streaming-media synchronize must be solved during the streaming-transfer. Streaming-synchronize is caused by the special quality of streaming-media data. So far, there is no universal model about streaming media-synchronize. There are a lot of problems about streaming media waiting us to study.The theme discusses the synchronization of a multi to multi streaming-media system. It contain synchronization inner streaming and synchronization between streaming and group synchronize only belongs to the multi to multi streaming media system. First, we introduce the developing situation of streaming media technology and synchronize and the streaming media transfer protocols. Second, we analyze construction of streaming media and limited-relation inner streaming media data and its time-space feature expressing. At last, we analyze the system synchronizations and give the corresponding synchronize arithmetic and control strategy to inner streaming and between streaming and the groups. And we deduce the minimum of memory for every receiver and the starting time offset of the first LDU of every code streaming playing in every receiver and the concrete method for judgment whether realize the group synchronization.
