Abstract

This paper proposed a video watermarking scheme which embeds watermarking directly in the compressed domain, and thus can be deployed in a real-time scenario. Our method embeds a pseudo-random sequence to the qualified AC coefficients for a number of selected 8 by 8 DCT blocks. The effects of motion compensation introduced by the video compression is carefully considered to reduce the watermark-interference, phenomena which can significantly affect the detection performance if not taken care of. Our scheme shows a low computation overhead and compatible robustness under moderate video compression
