In this paper, an improved video watermarking algorithm is presented for copy protection. Each video frame is divided into non-overlapping 8*8 blocks. Each block is a transformed 2D-DCT. After performing the same transformation to all the blocks and frames, embedding of image watermarking is performed with the selected DCT coefficients. Performance of the system is evaluated using peak Signal to Noise Ratio, Mean Square Error, Normalized Mean Square Error, Root Mean Square Error and Absolute Mean Error.


Keywords : Image, Video, Watermarking, Copy Protection, DCT.
