Robust video watermarking for MPEG compression and DA-AD conversion

In this paper, we proposed a robust video watermarking system. Using DCT domain spread-spectrum watermarking, our system achieved robustness to various non-hostile video processings such as MPEG compression, and DA-AD conversion. Our proposed system guarantees that 16-bit data can be extracted in any 15 second interval, even in a long video, by using adaptive frame selection. To verify the performance of the proposed system, various experiments were carried out under a DA-AD conversion environment. Experimental results show that the proposed method is not only robust to non-hostile video processings but also achieves invisibility.
