发明名称 APPARATUS AND METHOD FOR VIDEO SIGNAL WATERMARKING
摘要 <p>An apparatus for, and method of, encoding information into and decoding information from, a sequence of moving images, such as video images, MPEG. The present invention identifies moving and static portions of an image in an image sequence and provides two separate channels, one for the moving portion of an image and the other for a static portion of an image. One or more watermarking codes are then inserted into moving, or both moving and static image channels, so that moving image sequences including the watermark code are produced. Static edges and moving edges are detected by edge detectors for the purposes of encoding or decoding the image sequence.</p>
