Introduction to MPEG

MPEG Packet Elementary Stream - PES

A packet elementary stream is a raw information component stream (such as audio and video) that has been converted to packet form (a sequence of packets). This packetization process involves dividing (segmenting) a group of bits in an elementary stream and adding packet header information to the data. This packet header includes a packet identification code (PID) that uniquely identifies the packetized elementary stream from all other packetized elementary streams that are transmitted. PES packets are variable length packets that have a length limited determined by 16 bits length field in the header of each packet.

PES streams may include time decoding and presentation time stamps that help the receiver to decode and present the media. Decoding time stamps are the insertion of reference timing information that indicates when the decoding of a packet or stream of data should occur. A presentation time stamp is reference timing values that are included in MPEG packet media streams (digital audio, video or data) that are used to control the presentation time alignment of media.
