Digital watermarking video captured from airborne platforms
First Claim
1. A method of controlling an airborne platform, comprising:
- controlling capture of video depicting at least a portion of the earth'"'"'s surface, wherein the video is captured by a camera on the airborne platform;
obtaining geographical metadata associated with at least captured video;
controlling encoding of first digital watermarking in the video through alterations to data representing the captured video, wherein the first digital watermarking is generally imperceptible to a human observer of the captured video when rendered to the human observer, and wherein the first digital watermarking comprises or links to the geographical metadata;
controlling encoding of second digital watermarking in the video, wherein the second digital watermarking comprises a plural-bit payload that includes data representing a refinement to the geographical metadata; and
controlling transmission of the second digital watermarked video to a remotely located receiver on or in the earth'"'"'s surface.

Abstract
Digital watermarking technology is used in conjunction with video captured from airborne platforms (e.g., satellites, remotely controlled aerial vehicles and aircraft). One claim recites an airborne platform comprising: a camera for capturing video depicting at least a portion of the earth'"'"'s surface; and an electronic processor. The electronic processor is programmed for: obtaining geographical metadata associated with captured video; encoding first digital watermarking in the captured video through alterations to data representing the captured video, in which the first digital watermarking is generally imperceptible to a human observer of the captured video when rendered to the human observer in real time, and in which the first digital watermarking comprises or links to the geographical metadata; and controlling transmission of digital watermarked video to a remotely located receiver on or in the earth'"'"'s surface. Another claim recites: that the electronic processor is further programmed for: hiding second digital watermarking in data representing the captured video, the second digital watermarking comprising a plural-bit payload that includes data representing a refinement relative to at least some of the geographical metadata. Other claims and combinations are provided too.

13. An airborne platform comprising:
-
a camera configured to capture video depicting at least a portion of the earth'"'"'s surface; and a processor configured to; obtain geographical metadata associated with captured video; encode first digital watermarking in the captured video through alterations to data representing the captured video, wherein the first digital watermarking is generally imperceptible to a human observer of the captured video when rendered to the human observer in real time, and wherein the first digital watermarking comprises or links to the geographical metadata; hide second digital watermarking data representing the captured video, wherein the second digital watermarking comprises a plural-bit payload that includes data representing a refinement relative to at least some of the geographical metadata; and control transmission of the second digital watermarked video to a remotely located receiver on or in the earth'"'"'s surface. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
