摘    要:在点播电视、数据广播和数字电视系统中,为了客户的需要,常常需要对媒体流格式进行转换,这就涉及到对流进行解复用、多路ES流的复用。而复用和解复用必须考虑到缓冲区的控制策略。提出一种ES流复用时的缓冲区控制策略,并且使用这种策略成功地实现了VCD,DVD格式的数据转化为TS流的软件编程。

关 键 词:ES流  MPEG-2  TS流  控制策略  缓冲区  复用  STD

Abstract:In VOD, Digital broadcast, Digital TV, demultiplexing and multiplexing are necessary in order to transform a media stream format to another format according to customers' requirements. Demultiplexing and multiplexing must consider controlling strategy of buffere. A buffer controlling strategy of multiplexing of multiple elementaries was presented in this paper. With the strategy, we wrote a softwarwe that VCD and DVD format datum were transformed to MPEG-2 transport stream datum.
Keywords:buffer  multiplexing  system target decoder  video and audio
