A New Robust Video Watermarking Technique Using H.264/AAC Codec Luma Components Based On DCT

Video watermarking is well known as the process of embedding copy right information in video bit streams. It had been proposed in recent years to solve the problem of illegal manipulation and distribution of digital video . In this study, an effective, robust DCT transform using MATLAB. In the proposed method, first the video frames are extracted from the host video. Then, each frame gets watermarked with mul ti-level discrete cosine transform which is also known as embedding. After that each watermarked video frame gets reconstructed. Watermarked video is obtained after reconstruction of watermarked video frame. Experimental results shows that the proposed algorithm is imperceptible as well as robust against wide variety of signal and video processing attacks like Gaussian noise, cropping, geometric attack, , over writing etc. The technique is fairly acceptable and watermarked video is of good quality, achieves high PSNR and other results.
