The use of digital media applications , and copyright protection has obtained tremendous importance. Digital Watermarking is a technology used for the copyright protection of digital applications. A comprehensive approach for watermarking digital video is introduced. Hybrid digital video watermarking scheme based on Discrete Wavelet Transform (DWT) and Discrete Cosine Transform (DCT) has been proposed. Discrete Cosine Transform (DCT) with Principal Component Analysis (PCA) helps in reducing correlation among the wavelet coefficients. Wavelet decomposition of each video frame is done thereby dispersing the watermark bits into the uncorrelated coefficients. The video frames are first decomposed using DWT. The binary watermark is embedded in the low frequency wavelet coefficients. The imperceptible high bit rate watermark embedded is robust against various attacks that can be carried out on the watermarked video, such as filtering, contrast adjustment, noise addition and geometric attacks.
