摘要
通过研究系统级解复用过程中出现的PCR抖动问题,提出了两种解决的策略,尤其是在符合MPEG-2标准的前提下,对MPEG-2标准进行了一些改进,自定义了一些复用和解复用的协议,使得在系统级解复用过程中,能从多节目TS流中完整准确地恢复出单节目码流。
This paper proposes two solutions to reduce the effect of PCR throbbing during the process of de-multiplexing on system level.Some changes have been made on the premise of conforming with the MPEG2 protocol,for example,some multiplexing and de-multiplexing protocols have been user-defined in order to recover the single program code out of multi-programs TS accurately during the process of de-multiplexing on system level.
