Isochronous Distributed Multimedia Synchronization

Abstract

A multimedia system is characterized by the integrated computer-controlled generation, manipulation, presentation, storage, and communication of independent discrete and continuous media data. The presentation of any data and the synchronization between various kinds of media data are the key issues for this integration (Georganas, Steinmetz, & Nakagawa, 1996). Clearly, multimedia systems have to precisely coordinate the relationships among all media that include temporal and spatial relationships. Temporal relationships are the presentation schedule of media, and spatial relationships are the location arrangements of media. Multimedia synchronization is a process of maintaining these relationships by employing appropriate synchronization mechanisms and algorithms. Multimedia synchronization is traditionally challenging, especially in distributed environments.
