Study for error resilience in video compress coding

With the development of communication technique,network techniques,computer technology,error of transmission channel,not only can dagages the seriously video service quality.But also makes communication system collapse.So technique is an important part.This paper the video coding signal channel of system gave a detail description of the content and principle of error resilience technique,such as resynshronization,datapartitioning reverisible variable length coding,reference picture selection mode and error cocealment,which are use in diversified new video coding international standarda.This paper also gave some simulation results of error resilience technique based on MT-2200 channel models.The results shows error resilience technique can remarkably improve the subjective and objective quality of the reconstruted image.
