1. A method for facilitating the insertion of information into a video signal, the method comprising:
- embedding an information pattern in one or more regions of the video signal, a region comprising a plurality successive frames;
wherein, for one or more regions, the information pattern is embedded into a frame of a region with a relative degree of intensity and one or more frames of that region have the patterns embedded therein which have a relative intensity that differs from the relative intensity of the pattern embedded in other frames of the region.

14. A method for facilitating the protection of a video signal, the method comprising:
-
locating one or more watermark regions of a video signal for embedding a watermark therein, a region comprising a plurality successive frames;
for one or more watermark regions, embedding a watermark in a watermark region in an approximate plateau-shaped manner;
wherein the locating comprises randomly locating the one or more regions by randomly selecting frames of the signal, where each of the regions includes at least one of the selected frames. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A modulated video signal embodied on one or more computer-readable media and generated in accordance with acts for facilitating the protection of a video signal, the acts comprising:
-
fully encoding one or more frames of a region of a video signal with a watermark, wherein such frames are fully encoded with the watermark relative to unmarked frames;
partially encoding one or more frames of the region with the watermark, wherein such frames are partially encoded with the watermark relative to the frames of the fully encoding.

27. A modulated video signal embodied on one or more computer-readable media and generated in accordance with acts for facilitating the protection of a video signal, the acts comprising:
-
fully encoding one or more frames of a region of a video signal with a watermark, wherein the frames are fully encoded with the watermark relative to unmarked frames;
gradiently encoding at least one plurality of successive frames of the region with the watermark, wherein the plurality is gradiently encoded with the watermark relative to the unmarked frames and the fully encoded frames of the fully encoding.

28. An information pattern encoding system, the system comprising:
-
a video signal obtainer configured to obtain a video signal;
a region locator configured to locate one or more regions of the video signal, a region comprising a plurality successive frames;
a region marker configured to embed an information pattern in one or more regions of the video signal, a region comprising a plurality successive frames, wherein, for one or more regions, the information pattern is embedded into a frame of a region with a relative degree of intensity and one or more frames of that region have the patterns embedded therein which have a relative intensity that differs from the relative intensity of the pattern embedded in other frames of the region. - View Dependent Claims (29)
