In view of the copyright protection of digital videos,a blind video watermarking algorithm based on MPEG- 2 standard has been proposed by using human visual system( HVS) characteristics. Firstly,three 8 × 8 DCT blocks of the brightest B frames are selected as the watermark embedding positions,then the watermarking information is presented through block position and the growth trend of low frequency component,and finally the simulation experiments verify the invisibility and robustness of the algorithm.
