Abstract

This paper proposes a method of error detection and recovery by hiding specific information into video bitstream using fragile watermarking and checking it later. The proposed method requires no additional bits into compressed bitstream since it embeds a user-specific data pattern in the least significant bits of LEVEL's in VLC codewords. The decoder can extract the information to check whether there is an error in the received bitstream. We also propose to use this method to embed essential data such as motion vectors that can be used for error recovery. The proposed method can detect corrupted MB's that usually escape the conventional syntax-based error detection scheme. This proposed method is quite simple and of low complexity.
