Security and copyright protection are becoming important issues in multimedia applications and services, as Past few years have witnessed rapid growth in Digital video watermarking. Watermarking techniques have been proposed for these purposes in which the copyright information is embedded into multimedia data in order to protect the ownership. This paper presents a novel technique for embedding a binary logo watermark into video frames. The proposed scheme is an imperceptible and a robust hybrid video watermarking scheme. PCA is applied to each block of the two bands (LL – HH) which result from Discrete Wavelet transform of every video frame. The watermark is embedded into the principal components of the LL blocks and HH blocks in different ways. In this paper, a comprehensive approach for digital video watermarking is introduced, where a binary watermark image is embedded into the video frames. The proposed scheme is tested using a number of video sequences. Experimental results show high imperceptibility where there is no noticeable difference between the watermarked video frames and the original frames. Combining the two transforms improved the performance of the watermark algorithm. The scheme can be tested by applying various attacks .
