Synchronizing and optimizing multimedia communication with fuzzy clocks

An extension of the Yang-Huang Real-Time Synchronization Model (RTSM) based on fuzzy clocks is introduced (C.-C. Yang and J.-H. Huang, 1994). For ease of implementation of the fuzzy Real-Time Synchronization Model (fRTSM), timed hierarchical colored Petri nets (HCPNs) labeled with Occam code are used. The focus of the timed HCPN model for fuzzy real time synchronization of networked multimedia communication is in terms of adjusting the timer used in preserving prescribed a priori temporal relationships in the data for multimedia presentations and optimizing the use of network by a source of media data. Contribution of the fuzzy Real-Time Synchronization Model for multimedia communication is its selection of optional work in a multimedia presentation based on the output of a fuzzy clock. A basis for optimized allocation of network bandwidth to senders of multimedia presentations is also built into the fRTSM
