本文提出了一种基于H.264/AVC运动矢量的快速水印系统。通过限制对DCT系数和像素信息的访问，水印嵌入器/抽取器的计算复杂度保持在较低的水平，并且比H.264解码器低得多。监视由运动预测补偿引起的误差传播，并且其效果由仅基于来自比特流的运动信息的跟踪方法来限制。虽然本文的研究重点是H.264/AVC标准，但是这种新的水印技术同样适用于MPEG1-2和MPEG4视频标准
In this paper, we propose a fast watermarking system that works on the H.264/AVC motion vectors. By restricting access to DCT coefficients and pixel information, the computational complexity of the watermark embedder/extractor is kept low and much lower than that of the H.264 decoder. The error propagation due to motion prediction compensation is monitored and its effect is limited by a tracking method that is based solely on the motion information from the bitstream. Although this work focuses on the H.264/AVC standard, the novel watermarking technique is also applicable to the MPEG1-2 and MPEG4 video standards
