A Whole Rate-Distortion Optimize Pronounce Based on Wireless Sensor Network
Based on the Joint Video Team (JVT) of the ITU-T Video Coding Experts Group VCEG and the ISO/IEC Moving Picture Experts Group MPEG,an RD optimal Macro Block mode decision scheme for Internet error channel streaming is introduced.The scheme employs tne luminance Rate Distortion (RD) optimal mode decision scheme so as to take the effects of video encoding distortion and the channel error propagation to get higher error robustness for error transmission.Based on the Wireless Sensor Network,this paper analyzes the data distortion problem when transmitting H.264 coded video stream over error-prone channel.And the authors also have discussed a widely accepted technique that introduces more intra-coded information on macro block basis.Additionally,this paper introduces a simple loss and multiplication factor estimation method,the rate-distortion optimized assessing strategy over the whole situation.
