Abstract
Digital watermarking technology proposed in recent years is a new technology for copyright protection and authentication for digital contents. Compared with still pictures, video watermark technology must meet the blind-detection requirement. In this paper, according to the feature of motion vector, a new video watermark algorithm based on motion vector is presented. Experimental results show that the proposed algorithm can meet the real-time requirement of video watermarking, and it is also compatible with present video compression standards. The embedded watermark does not affect the I-frame image quality and can be extracted blindly.
