Group or inter-destination media synchronization (IDMS) addresses the presentation of a stream at all the receivers of a group, simultaneously. To ensure synchronized delivery of multimedia information, intelligent synchronization protocols/techniques are required. This article illustrates various issues on intra- and inter-media synchronization and presents the basic schemes for inter-destination media synchronization (IDMS). It presents in short IDMS standardization efforts and novel solutions for new multimedia applications. Finally, it outlines future research directions for multimedia group synchronization.
