Abstract
A video signal transmission system transmits a video signal and data corresponding to the location and size of active areas for some of the frames of the video signal (but not other frames of the video signal). A video reception and display system determines the location and size for the active areas based on an interpolation technique. A viewer can click on the active areas to thereby link the receiving system to a web page or other information source.
