According to MPEG-2 video features,a video watermarking algorithm is proposed. The positioning is achieved by using I-frame and P-frame of GOP,and the watermark information is embedded in a plurality of B frames. In determining the embedding strength,adaptive threshold is embedded by using human visual characteristics method. The simulation tests showed that the algorithm has good transparency and robustness.
