A method for annotating a video image to include interactive links comprises the step of manually establishing active areas (114) in a subset of the frames of the video image, and using interpolation to establish the active areas for the remaining frames. The active area is an area of a screen (514) where a viewer can place a cursor and click, to thereby activate a link. This link could be a link to a URL or some other kind of link. The interpolation can be a linear interpolation or a spline interpolation technique. The video image can be communicated to a viewing system along with annotation corresponding to some of the video frames but not others of the video frames. The receiving system can determine the active areas for the others of said frames by interpolation. |
