Error Detection Scheme for H.264/AVC using Error-Control Coded Copyright Information

摘要

This paper proposes a new copyright protection and video error detection scheme for H.264 video using information embedding technique and Error Control Coding (ECC). At the H.264 encoder, the ECC coded copyright information and the parity bit of the sums for the non-zero coefficients in 8x8 sub-blocks are embedded into the selected "optimal position" in the intra frames of the encoded video. Then the embedded information can be used to detect the transmission errors in the video at H.264 decoder. After the error detection process, the embedded copyright information can be extracted and automatically reconstructed even if the information is corrupted. Experimental results show that the proposed scheme can efficiently protect the copyright information and detect more video errors than the standard H.264 codec.
