Paper Abstract

To overcome the problem that the video information packet lost occasionally when the video stream transfers in the low dependable channel, it is absolutely necessary to adopt effective error control technique to recover the false video signal. According to the multiple-reference frames characteristic of H.264/AVC, this paper improves the traditional boundary matching algorithm and proposes a multiple-reference frames enhanced weighted boundary matching error concealment algorithm. The simulation experiments show that the proposed algorithm improves the limitations of the traditional temporal error concealment and decreases the matching distortion contrasting normal single-reference frame boundary matching algorithm at the condition of strong movement and video scenes switching. Therefore more exact motion vector would be obtained to restrain the diffusion of video error effectively. Moreover, the improved algorithm run on decoder end, without any changes of H.264 video stream structure and extra burden in transport channel, and has wide adaptability in multiple media transmission.
