Macroblock Importance Estimation Based Resynchronization Approach
Resynchronization is an important error resilient approach for rideo transmission.The video transmission distortion was analyzed and a new macroblock importance estimation based resynchronization approach was proposed.Through the definition of macroblock importance estimation,the approach utilized the macroblock importance combining with the bit stream length to packet compressed video with the same importance The proposed approach is compared with number of macroblock based method and bit stream length based method by different test sequences for the same video packet loss pattern.The experimental results show that the new approach can decrease video quality fluctuation in error prone channel and increase subjective quality greatly.
