In this paper, a novel marking algorithm for IP Diffserv based on the transmission condition and the different importance of video streams for decoder has been introduced. Using the marking algorithm, video transmission over the IP Diffserve networks model, which we have set up has been studied. Combined with the error concealment technology in the video decoder, in case of severe congestion, which causes the lose of a lot of IP packets, the algorithm has been proved effective, hence the delay, jitter and the perceived picture quality entirely meet requirement for real-time video transmission.
