✦ Synopsis

In this paper, we present a new user-aware adaptive object-based video transmission approach to heterogeneous users over the next generation Internet. Firstly, we describe a new transport framework for complex multimedia applications over the next generation Internet, which provides di!erentiation functionality within one IP session as well as among di!erent IP sessions. It includes application-aware intelligent resource control at the edge of the network, fast transcoding and signaling in the network. Secondly, we propose a new bitstream classi"cation, prioritization and packetization scheme in which di!erent types of data such as shape, motion and texture are reassembled, assigned to di!erent priority classes, and packetized separately based on their priorities. Thirdly, we present a simple but e!ective mechanism of object-based dynamic rate control and adaptation by selectively dropping packets in conjunction with di!erentiated services (Di!serv) to minimize the end-to-end quality distortion. Finally, we perform the queuing analysis for our mechanism and explore how to extend our approach to the multicast case. Experimental results demonstrate e!ectiveness of our proposed approach.
