A real-time synchronization model and transport protocol for multimedia applications

Abstract

In considering transport layer protocol for multimedia applications in packet networks, real-time and synchronization characteristics of multimedia applications have to be considered. Synchronization means that intermedium temporal relationship for an application has to be satisjied, after the transmission across the network. Since the random delay of packet networks makes synchronization among media more complicated; therefore, a model is required to specify the temporal relationship among media across the network and can be easily implemented in a transport protocol. In this paper, a realtime synchronization model (RTSM), is presented for synchronization, and a new protocol, namely MSTP (Multimedia Synchronization Transport Protocol), is proposed based on RTSM.
