SYNCHRONIZATION OF MULTIMEDIA DATA FOR A MULTIMEDIA NEWS-ON-DEMAND APPLICATION

In this paper, we present a complete software control architecture for synchronizing multiple data streams generated from distributed media- storing database servers without the use of a global clock, Independen t network connections are set up to remote workstations for multimedia presentations, Based on the document scenario and traffic predictions , stream delivery scheduling is performed in a centralized manner, Cer tain compensation mechanisms at the receiver are also necessary due to the presence of random network delays, A stream synchronization proto col (SSP) allows for synchronization recovery, ensuring a high quality multimedia display at the receiver, SSP uses synchronization quality of service parameters to guarantee the simultaneous delivery of the di fferent types of data streams. In the proposed architecture, a priorit y-based synchronization control mechanism for MPEG-2 coded data stream s is also provided, A performance modeling of the SSP is presented usi ng the DSPN models, Relevant results such as the effect of the SSP, th e number of synchronization errors, etc., are obtained.
