MPEG-2 Video Compressed Watermarking
Mahak · Journal of Emerging Technologies and Innovative Research · 2016
Video watermarking is an important method of protecting the intellectual property copyright of the video media. In this paper a video watermarking based on MPEG-2 video compression is proposed. MPEG video compression is used in many current and emerging products. These applications benefit from video compression in the fact that they may require less storage space for archived video information, less bandwidth for the transmission of the video information from one point to another or a combination of both. First starting with MPEG-2 compressed video standard and then the algorithm principle of video watermarking is given, after video streams are partly decoded, the watermarking information modulated by m sequence is embedded into the direct current coefficients of chroma DCT of video I frame or P frame.
