1. A method comprising:
- receiving a video image from a video image source, wherein said receiving is performed at a location remote from said video image source;
displaying said video image as a sequence of frames on a display device, wherein said display device is at said location remote from the location of said video image source;
receiving at said location remote from the location of said video image source information corresponding to the location of at least one active area for some of said frames but not others of said frames, wherein said location remote from the location of said video image source is also remote from the source of said information corresponding to the location of at least one active area; and
determining at said location remote from the location of said video image source the location of said active area for said others of said frames by interpolation.

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.

11. Method comprising:
-
communicating from a first location to a second location remote from said first location a video clip comprising a set of video frames, some of the video frames within said set of video frames being annotated such that an active area is established for said some of said video frames;
communicating from said first location to said second location the location of said active area for said some of the video frames within said set of video frames and not others of said video frames within said set of video frames;
receiving said video clip and the location of said active area for some of said video frames within said set of video frames and not said others of said video frames, said receiving being accomplished at said second location; and
establishing positions for said active area within said others of said video frames by interpolation, said establishing being accomplished at said second location. - View Dependent Claims (12, 13, 14, 15)

16. A system comprising:
-
a receiver for receiving a video signal from a video signal source;
a display coupled to said receiver for displaying a video image corresponding to said video signal, said video image comprising a set of frames; and
a circuit receiving information indicating the position of at least one active area for some of said frames and not others of said frames, said circuit determining the location of said active area for said others of said frames by interpolation based on the location of said active area for said some of said frames, wherein said receiver, display and circuit are remote from said video signal source and the source of said information. - View Dependent Claims (17, 18, 19)

26. A method comprising:
-
receiving a video image at a first location;
displaying said video image as a sequence of frames on a display device at said first location;
receiving information corresponding to the location of at least one active area for some of said frames but not others of said frames at said first location, wherein said first location is remote from the source of said information; and
determining at said first location the location of said active area for said others of said frames by interpolation.

27. Method comprising:
-
communicating to a first location a video clip comprising a set of video frames; and
communicating from a second location to said first location the location of an active area for said some of the video frames within said set of video frames and not others of said video frames within said set of video frames, said second location being remote from said first location;
wherein said communicating is accomplished such that the active area for said others of said video frames are established by interpolation at said first location.
