Abstract:

In order to achieve synchronization between the media transmission,we analyzed the characteristics of multimedia data, made the composition of multimedia data in the time domain, studied the relationship between multimedia synchronization, and compared the current method of transmission of multimedia synchronization. And a relative time-stamp synchronization scheme based on feedback control without synchronous clock of whole power was brought forward.In order to assure media synchronization we set up the buffer in the receiving end to offset delay. The method is simple, because it does not require accurate time, but only marking audio and video time-stamp simultaneously.
