The study of digital video watermarking algorithm based on the protection of multimedia courseware

With the rapid development of the network technology and multimedia technology, the digital video watermarking technology has been becoming an effective method to protect the copyright of multimedia courseware. The paper proposes an improved digital video watermarking algorithm based on the protection of multimedia courseware according to the analyzing the traditional method of multimedia courseware copyright protection. In this paper, the streaming video watermarking embedding scheme of protecting multimedia courseware copyright has been designed by using the algorithm, meanwhile, the algorithm has been studied, the study shows that the algorithm can improve the effect of the video copyright protection greatly.
