| Traditional Video compress are Discrete Cosine Transform encode based on detach block, which has good irrelated and energy compress performance, has become the most Image/Video compress international standard of kernel technology. However, block effect and flying mosquito yawp based on DCT picture is inevitable. So how to provide many extended encode struct , for instance, quality,resolution is the topic that many project teams studies, which could realize multi resolution encode ,embedded encode and could provide personal service to user in wireless environment. The Video compress based on Wavelet could need the most of necessary character of modern application, such as multi resolution encode , multilayer quality control, embedded code stream, which could be mixed together entirely. Wavelet transform is the newest and important develop direction of transform encode.This paper study deeply the wavelet transform theory and statistical image encode arithmetic ,and improve on embedded zerotree wavelet arithmetic. Based on spatial domain, transforming field, three dimension wavelet ,this paper study wavelet field motion compensation technology and put forward an improved Video encode arithmetic of wavelet field motion compensation based on motion field.Based on wavelet transform theory ,the paper uses the video encode arithmetic which is provided in the paper to encode the video data, comparing compress rate and loss rate of data with H.263 compress technology, we found higher compress rate and less loss rate. To improve the function of Video Meeting System, produce the Synchronization of Audio and Video and support the dynamic IP Address. Video Meeting System have more powerful function and become a full real Video Meeting System. |
