MPEG-2 TS流的拼接问题

Splicing of MPEG-2 TS

节目拼接技术是MPEG-2节目编辑的关键技术之一。基于MPEG-2TS流的拼接技术可以不必修改PES包而直接在TS流中实现单个节目或多个节目之间的拼接。本文在简要介绍了TS流的基础上着重阐述了TS流拼接的一般方法,并对作为其功能扩展的拼接信息表技术作了简单的说明。

As the level of digitization at TV stations is being constantly heightened, the MPEG-2 has become a mainstream format for edit and storage. The edit between different programs in MPEG-2 TS, therefore, is now a hotspot of researches in related fields. After a brief introduction of TS a special effort is made to expound common methods of TS splicing and the splicing information list technology as an extension of splicing functions is explained.
