Overview: MPEG systems
MPEG systems containers multiplex timed elementary streams in arrangements suited to different storage and delivery conditions.
A transport stream and a program stream both carry related media streams, but their packaging serves different environments. Transport-stream packetization and programme identification are especially relevant to continuing broadcast or network sources. These pages explain the container choice before moving into the codecs carried inside it.
MPEG transport stream (TS and M2TS)
MPEG transport stream interleaves encoded media and programme information in small fixed-size packets suited to continuous delivery.MPEG program stream
MPEG program stream multiplexes related encoded streams into variable-size packs for storage and playback in comparatively reliable environments.
