A novel video watermarking scheme based on motion vectors and DCT coefficients is proposed in this paper.In the field of video watermarking scheme based on compressed domain，the scheme based motion vectors and the scheme based on DCT coefficients have become a hot research topic，but there are both advantages and disadvantages in each scheme.So a hybrid video watermarking scheme based on motion vectors and DCT coefficients is proposed.The watermark is embedded in motion vectors and DCT coefficients of the video sequence.And the two kinds of watermark can be corrected for each other.Experiments indicate that after embedding the watermark，both the objective video quality and the subjective video quality are the same as that of original video sequence and the increasing of bitrates is controlled in 1%.
