Summary

This Recommendation | International Standard specifies generic methods for multimedia multiplexing, synchronization and timebase recovery. The specifications provide a packet based multimedia multiplexing where each elementary bit stream is segmented into Packetized Elementary Stream (PES), and then respective packets are multiplexed into either of the two streams: Program Stream (PS) which is a multiplex of variable length PES packets and designed for use in error free environments, Transport Stream (TS) which consists of 188 byte fixed length packets, has functionality of multiple program multiplexing as well as multiplexing of various PES packets and is designed for use in error prone environments. The multimedia synchronization and timebase recovery are achieved by time-stamps for system time clock and presentation/decoding.
