A Content-Adaptive Digital Watermarking Scheme in H.264/AVC Compressed Videos

A digital video watermarking scheme under the framework of H.264/AVC is proposed in this research. The watermark signal is embedded into quantization indices of intra-coded slices to ensure both the effectiveness of watermarking and the compact size of video data. The luminance masking of Watson´s visual model is employed to guarantee the imperceptibility of watermark signal. The coding procedure of H.264/AVC is taken into account in the design of watermarking procedures to achieve efficiency. An application of the watermarking scheme on authenticating digital videos will be shown in the experimental results, which demonstrate the feasibility of the proposed system.
