De-jittering in the transport of MPEG-4 and MPEG-2 video over ATM

In this paper a de-jittering scheme which can be used in the transport of MPEG-4 and MPEG-2 video to absorb any introduced network jitter is proposed. The essence of the de-jittering scheme is based on the statistical approximation of delay variation in the arrival times of video packets carrying encoded clock reference values and a filtering and re-stamping mechanism. In addition, a brief overview of the MPEG-4 system is presented.
