Robust and stealthy video watermarking into regions of successive frames
First Claim
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 of successive frames and not embedding the information pattern in one or more different regions which are interposed between the one or more regions;
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.

Abstract
A technology is described herein for the protection of rights in the content of a video sequence. In one example the technology embeds an information pattern in one or more regions of a video signal. A region includes a plurality of successive frames. The example does not embed the information pattern in one or more different regions which are interposed between the one or more regions. Further, in this example, for one or more regions, the information pattern is embedded into a frame of a region with a relative degree of intensity. 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.

13. 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 of successive frames; and
,embedding a watermark in individual watermark regions in an approximately plateau-shaped manner, such that the watermark is embedded on a first frame of the region which is interposed between second and third frames of the region, and wherein the watermark is embedded on the first frame at a relative intensity which is greater than a different relative intensity at which the watermark is embedded on the second and third frames. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. 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 of successive frames; and
,a region marker configured to embed an information pattern in one or more regions of the video signal, wherein, for an individual region, the information pattern is embedded into a frame of the region with a first relative degree of intensity and wherein the first frame is interposed between additional frames of that region that have the patterns embedded therein at a different relative intensity. - View Dependent Claims (23)
