Description
Summary:Digital watermarking is the technique which embeds the invisible signal into multimedia data such as audio, video, images, for copyright protection, including owner identification and copy control information. This paper proposes a new watermarking technique which is appropriate for MPEG2 video coding system by extending the direct sequence spread spectrum. The proposed watermarking scheme in this paper minimizes the degradation of video quality caused by embedded watermark. And this technique can also directly extract embedded watermark information from watermarked MPEG2 compressed video stream without using original video sequences, which is robust for various attacks and appropriate for real time implementation.
