Real-time MPEG2 video watermarking in the VLC domain

This paper proposes a compressed domain video watermarking scheme for copyright protection. Our scheme is designed based on the concept of communications with side information. For making the real-time detection a reality, the watermark is directly embedded and detected in the VLC domain. The typical problems of video watermarking such as preservation of bit rate, video attacks, real-time detection is examined. The performance of the new watermarking scheme is examined by checking its robustness capability against attacks together with false positive analysis.
