提出了一种可产生任意码率的MPEG2系统层码流发生器的设计。该方法根据MPEG2系统层传送流的时序要求,采用修正节目参考时钟(PCR)和适当插入空包的方法进行传送流码率的上变换。它适用于需要修改传送流码率的系统中。%A design for upconvert the bitrate of MPEG-2 system transport stream is discussed which is used in MPEG-2 transport stream generator. Based on modifying the Program Clock Reference (PCR) and inserting empty packets properly, the method can upconvert MPEG-2 transport stream bitrate successfully. This method is also useful in other systems needed to convert MEPG2 transport stream bitrate.
