Abstract: - Digital video watermarking has been widely used technology for copyright protection of the digital media. It prevents the illegal distribution of the digital data. Watermarking is the process of embedding some information in the digital media and then transmitting it. The extraction of this watermark will indicate the originality of the digital data. The additional information could be very easily transmitted along with the video without affecting the quality of the original video. In this paper, a hybrid approach based on two effective techniques is used. The first technique Discrete Wavelet Transform divides the video frames into sub-bands and the second technique Principal Component Analysis is applied on each LL and HH sub blocks. Watermark is embedded into those sub-bands to obtain the watermarked video as good as that of the original video.
