Abstract

This paper has proposed and implemented a new approach to detect MPEG-2 header errors using a MD5 hash function and information hiding technique. The video picture header information is protected by a MD5 hash technique, and any change in the header level is detected immediately. The information hiding technique is used to locate the error block number in the corrupted MPEG-2 video. The results show that the new approach can detect 100% of header error at both block level and higher levels without increasing the transmission bit rate.
