Packaged elementary stream

from Wikipedia, the free encyclopedia

A packetized elementary stream or packetized elementary stream (PES) is a data stream in the specification of MPEG-2 is described in Part 1 (Systems) (ISO / IEC 13818-1) and ITU-T H.222.0. An audio or video encoder generates a packetized elementary stream by packing the generated data stream (elementary stream) into standardized packets, each with a PES packet header. In a second step, elementary audio and video streams packaged in this way can easily be combined into program or transport streams for a DVD or DVB .

The data packets of such streams can vary in size from packet to packet; this is to be expected for video sequences. To embed such a stream in a transport stream , the packets are subdivided again, since a transport stream uses small packets with only 188 bytes and the data content in these packets is therefore very low.
