提出一种基于MPEG-2的视频水印方案，利用分组调制技术，将影视作品的版权信息嵌入到低频DCT系数中，以此来保护版权。实验结果表明，该算法生成的视频质量较高，同时算法在抵抗旋转、剪切、缩放、投影攻击方面具有较强的鲁棒性。

We propose an MPEG-2-based video watermarking algorithm,which uses grouping modulation technology to embed the copyright information of film and television works into low-frequency DCT coefficient as the way to protect their copyrights.Experimental results show that the video generated with the proposed algorithm has higher quality,meanwhile,the algorithm also has stronger robustness in resisting the attacks of rotation,cutting,zooming and projecting,etc.
