英文摘要: The project focuses on processing, transmission and applications of the wireless multimedia content using network aware information processing scheme to deal with the challenges of the wireless network multimedia techniques and applications. The detail research points of the project include dynamic awareness and QoS parameters adjustment of the wireless networks, cross-layer joint optimization of application layer, network layer and link layer of the networks, video quality improvement by super-resolution, resolution conversion and error concealment for heterogeneous networks and terminals, copyright protection and authentication by watermarking and etc., and finally implement of a hybrid distributed stream multimedia platform by combining P2P with client/servers. The main achievement of the project is to use the idea of network aware multimedia information processing which combines the distributed multimedia content processing with network transmission techniques for guarantee the network and terminals QoS. The research results of the project will provide theory support for the future broadband wireless multimedia networks design and applications.
