Recently, transcoding of the video contents in the environments of heterogeneous multimedia services-wired/wireless Internet and mobile networks using cellular phones, DMB(Digital Multimedia Broadcasting), IPTV(Internet Protocol Television) etc. - is raised up as a new issue. Therefore, video watermarking techniques are confronted with difficulty about not only existing video compression but also a modification considering time and spatial resolution under transmission bandwidth. In this paper, for the transcoding, we proposed a new video watermarking scheme based on DWT framework using multiresolution property of DWT and binary image watermark playing a role of synchronization pattern. In the experimental results, we confirmed robustness and invisibility of the proposed scheme about transcoding.
