英文摘要: In order to meet the demands of the adaptive transmission and optimal video quality, the theory and technology about the models of multi-dimension rate control and net transmission for scalable video coding was studying in this project. The main works are as fallows. Firstly, provided some scalable schemes for video coding and transmitting. Secondly, multi-dimension rate control was built based on video trace file. Thirdly, rate control system for scalable video coding was provided to adapt net condition based on the video trace file. Fourthly, the conclusions were adopted by the nation standard. Finally, scalable video coding was used to transmit the video among terminals in the digital house.
