| Abstract: | Firstly, this paper introduces an algorithm of watermark on digital video, then it gives some reformative idea in allusion to the problem of the small watermark capacity of the arithme tic. At last, it provides the implement process and the experimental result. The result shows that this algorithm achieves the antieipative ends and has a try on transforming digital video watermark into production and its application in the field of streaming media successfully. |
