提出了一种新的H. 264/AVC水印算法。该方法将鲁棒水印嵌入到DCT域，将脆弱水印嵌入到运动矢量中，实现了版权保护和认证的联合。我们的方案优于其他视频水印方案在更高的水印容量，特别是在较低的压缩比特率。此外，与H.264/AVC中用于模式选择的拉格朗日优化很好地对齐，所提出的方案仅向视频内容引入小的失真。实验结果也表明，该解决方案是非常计算效率在水印提取。
A novel H.264/AVC watermarking method is proposed in this paper. By embedding the robust watermark into DCT domain and the fragile watermark into motion vectors respectively, the proposed method can jointly achieve both copyright protection and authentication. Our scheme outperforms other video watermarking schemes on higher watermarking capacity especially in lower compression bit-rates. Furthermore, being well aligned with Lagrangian optimization for mode choice featured in H.264/AVC, the proposed scheme only introduces small distortions into the video content. Experimental results also demonstrate that the proposed solution is very computationally efficient during watermark extraction.
