在MPEG-2 TS流内实现字幕信息的插入,避免了对MPEG-2数据进行解码-编码的过程,是在数字电视广播(DVB)中插入字幕信息的一种灵活而有效的方法,对DVB字幕进行介绍,并提出一种在TS流中插入DVB字幕的实现方法。

It is a flexible and effective method to insert the DVB subtitling information into the MPEG -2 Transport Stream, which avoids the decoding and coding of the MPEG - 2 original Transport Stream.
