Abstract :
Two classifications of robustness were given in video digital watermark. Then extracting watermark was deduced to sample overlap in two random samplings. With the help of "two thirty" conclusion, a new algorithm was proposed with high reliability and robustness. The proposed algorithm can resist frame-edit attacks efficiently which are familiar and hard to solve. And it supplies an important technical method for practical applications of video digital watermarks.
