On the basis of H.264 video coding standard,a video watermarking scheme is proposed.Through the analysis of the H.264 inter- frame predictive coding features,combined with H.264 interframe the characteristics predictive coding principle and the human visual system to select the MV P frame macroblocks as watermarking information embedding objects.The MV is quantified,to get two independent regions.According to the different watermarking information,through modifying the motion vector so that it points to the different regions,the spread spectrum technology is used to realize the watermarking embedding.In order to improve the robustness of watermarking.The experimental results that this scheme can resist re- coding compression,load noise,frame average attack,showing better robustness.
