Mechanisms of MPEG Stream Synchronizatio n G J L,u, H K Pung and T S Chu a Department of Information Systems and Computer Scienc e National University of Singapor e Singapore 051 1 Abstract Media synchronization is an important issue in developing multimedia applications . MPEG is an international standard for coding moving pictures and associated audio for multimedi a applications . Coded audio, video and other data streams are multiplexed into an MPEG stream . We introduce the syntax of the multiplexed MPEG stream and explain the mechanisms used t o maintain media synchronization in a hypothetical model, system target decoder, in which it i s assumed that data transfer and decoding are carried out instantaneously . Then we propos e extensions to these mechnisms to achieve MPEG stream synchronization in a practical decoder . le Introduction MPEG (Motion Picture Expert Group) is an international standard for coding of moving pictures and associated audio for digital storage media up to about 1 .5 Mbit/s, prepared by ISO/IEC JT C 1/SC 29/WG11[l] . The draft standard [1] was published as ISO/IEC 11172 . When referring to this standard, MPEG and ISO 11172 are used interchangeably . The standard
