Imperceptibility and robustness including complexity are important issues in watermarking system, so it is desirable to consider these issues on design of watermarking system. In this paper, we will propose one of video watermarking in which motion between three continuous frames is utilized in order to provide the imperceptibility, robustness and acceptable complexity. Region R for watermarking is retrieved from three frames f(t), f(t+1) and f(t+2), and the watermarks which conveys a payload of L bits are embedded into DCT coefficients of Region R. Experimental results show that the proposed method could provide good fidelity and the robustness against MPEG-2 compression as well as some frame attacks.
