What are the different MPEG-2 Systems components?
MPEG-2 Systems provides a two layer multiplexing approach. The first layer is dedicated to ensure tight synchronisation between video and audio. It is a common way for presenting all the different materials which require synchronisation (video, audio, and private data). This layer is called Packetized Elementary Stream (PES). The second layer is dependent on the intended communication medium. The specification for error free environments such as local storage is called MPEG-2 Program Stream, while the specification addressing error prone environments is called MPEG-2 Transport Stream.
