Today’s life internet offers great convenience in transmitting large amount of data in different parts of the world. However, the safety and security of long distance communication remains an issue. In order to solve this problem has led to the increase in the need of copyright protection. The application of video watermarking in copy control, broadcast monitoring, copyright protection, video authentication, finger printing, annotation etc. is immensely rising. The main objectives of video watermarking are undetectability, robustness, and capacity of hidden data. Video watermarking algorithms normally prefers robustness. In this paper, techniques used in video watermarking are discussed with the literature survey and then the shortcoming are analyzed and as conclusion proposal for new points for hiding watermark in video is given.
