Abstract

Video watermarking plays an important role intoday´s copyright protection of video media, in this paper a blind watermarking algorithm for mpeg2 video is proposed. In this algorithm, several DCT intermediate frequency coefficients of the video pictures are selected and divided into some groups, the watermark was embedded into the video pictures by adjusting the intermediate frequency coefficients in each group. The watermark capacity of this algorithm is adequate and experimental result shows the proposed algorithm is robust to video compression attack within a certain range and has little effect on the quality of the video.
