The growing demand for on-line multimedia applications has posed a new set of challenges in the networking, modeling and scheduling scheme for transmitting multimedia data. Using the MPEG-4 data for the online multimedia applications will be one of the solutions for solving the congestion and synchronization problem. In this thesis, a general communication framework for synchronous delivery of pre-orchestrated/stored MPEG-4 multimedia data in a network environment is presented. We propose using the Object Composition Petri Net (OCPN) model to capture the synchronization requirements among temporally related multimedia objects, and further design a synchronization scheme for MPEG-4. The aim of this approach is to demonstrate the tradeoff between resource allocation (e.g. bandwidth and bu...[ Read more ]

The growing demand for on-line multimedia applications has posed a new set of challenges in the networking, modeling and scheduling scheme for transmitting multimedia data. Using the MPEG-4 data for the online multimedia applications will be one of the solutions for solving the congestion and synchronization problem. In this thesis, a general communication framework for synchronous delivery of pre-orchestrated/stored MPEG-4 multimedia data in a network environment is presented. We propose using the Object Composition Petri Net (OCPN) model to capture the synchronization requirements among temporally related multimedia objects, and further design a synchronization scheme for MPEG-4. The aim of this approach is to demonstrate the tradeoff between resource allocation (e.g. bandwidth and buffer size) and system performance in the MPEG-4 System. At the same time, the proposed modeling and scheduling scheme can also enhance the flexibility of the MPEG-4 multiplexer layer (FlexMux) for transmitting MPEG-4 multimedia data over a communication network.
