In this paper, a video watermarking scheme is proposed, which has high capacity and is robust against transcoding between MPEG2, MPEG4 and H.264. In the proposed scheme, the watermark is embedded into the DCT blocks and the frames in the same GOP are watermarked with the same watermark. During the embedding, the spatial relationship of DCT coefficient between an 8*8 block and its four 4*4 sub-blocks is exploited to select out the coefficients which are affected slightly by compression and… CONTINUE READING
