METHOD AND APPARATUS FOR PROCESSING TRANSPORT STREAMS

摘要

A method of processing two or more transport streams, each stream comprising video packets and audio packets, comprises locating switch points at the same positions in each of the streams based on video packets in each stream. Then a check is performed in each stream whether the audio packets whose payloads form a given PES packets are located between two adjacent switch points or are split across switch points. A step of arranging packets in each of the streams is performed such that audio packets whose payloads relate to given PES packets within each stream are located between the same two adjacent switch points in each of the streams. Additionally, a step of comparing the clock reference value of the streams immediately after each switch point and writing a common clock reference value into the packets of the streams immediately after each switch point is performed.
