New Packetization Method for Error Resilient Video Communications

摘要

In this paper, we present an efficient video packetization method and associated video compression / decompression methods for the increase of error resilience of video communications over error-prone packet-switched networks. The main idea is inspired from the Multiple-Description Coding (MDC) strategy in which each image is separated into two sub-images like interlaced scanned image. The main contribution of this paper is the modification of RFC2429 packetization method and video compression and error concealment methods for the sub-images. The simulation results show that the proposed method significantly improves the subjective and objective quality compared with conventional RFC2429 packetization and TCON-based decoding method.
