An Video Watermarking is proposed to improve the robustness against collusion attacks. The Using this new algorithm, all video frames are first divided into several sets so that frames of each set carry the same watermarks. Then in each group of frames, watermark is estimated. it has been shown that the watermarking maker can use this algorithm to build sets of frames carrying the same watermark for avoiding collusion attacks.
