To prevent more and more electronic information from being pirated, attacked, the digital video watermarking technology is a very good method to resolve the copyright protection of the electronic information products. In this paper, watermarking-based copyright protection techniques of the digital video is summarized. First, briefly introduces the application background and characteristics of video watermarking. Then gives the embedding and detection algorithms in common.At last, some key techniques that should be noticed in practical application are pointed out, such as frequency expanding, correct and code, suppose by mistake that waits for technology in embedding of the relevant measuring, video watermark.In all,there will be a wide development prospect in digital video watermarking technology.
