摘要：

Multiple description (MD) video coding generates several descriptions so that any subset of descriptions can reconstruct video, which provides much error resilience. But most of current MD video coding schemes are for two descriptions and for "on-off" channels, which is not suitable for packet-loss networks. This paper proposes a scheme to enhance the error resilience of traditional MD video coding in such environment, by periodically inserting S frames, a kind of switching frame, in the video stream to make good description recover the 'bad' description, with very small redundancy. This proves to perform well in packet lossy networks especially lower packet loss rate.
