Abstract
Digital video is a group of moving visual images, text and sounds. The popularity of using digital video in Internet
leads to illicit copying and dispersal of content. In order to avoid this, video watermarking technique are used as a
preventive measure for illegal copying of copyrighted material. In this paper, watermarking algorithm for identification of
optimal frames and embedding of nested watermark using static block selection is proposed. The nested watermark is
embedded in the uncompressed video data and is extracted without the use of original video sequences. These algorithms
preserve the video quality and provide more security. The performance of the algorithm is analyzed using Peak Signal to
Noise Ratio, Normalized Correlation and Mean structure similarity index with respect to various attacks. Experimental
evaluation demonstrate that the proposed algorithm perform satisfactorily compared to traditional algorithms in terms of
payload, transparency and it is also robust against various attacks.
