Abstract
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.
