摘要

本文提出了一种视频水印技术，通过对MPEG-2视频比特流中的运动矢量进行轻微修改来隐藏版权信息。该方法将水印嵌入到大值运动矢量的运动残差中，然后将运动残差正则化成一个修改后的比特流，从而方便准确地提取水印信息。实验结果表明，该技术对MPEG解码速度影响小，对感知效果影响小，能够在短视频序列中嵌入水印，可以直接在压缩和未压缩的视频序列上加水印。

A new method of MPEG video watermarking technology

In this paper, we propose a video watermarking technology to hide copyright information by a slight modification of the motion vector in MPEG-2 video bit stream. In this method, watermark is embedded in the motion residual of large value motion vector, then the motion residual are regularized into a modified bit stream from which the watermark information can be retrieved easily and exactly. From the experimental results, this technology has the advantage of little influence on the MPEG decoding speed, little degrading the perceptive effect, capability to embed watermark in a short video sequence, and can be used to watermark directly on compressed and uncompressed video sequence.
