Digital Watermarking Compressed Video Captured From Aerial Sensors
First Claim
1. A method comprising:
- capturing video depicting at least a portion of the earth'"'"'s surface, the video captured by an aerial, unmanned apparatus;
compressing the captured video;
obtaining geographical metadata associated with at least the captured video; and
hiding a first digital watermark in the compressed captured video through alterations to data representing the compressed video, wherein the first digital watermark is generally imperceptible to a human observer of the video, and wherein the digital watermark comprises a plural-bit payload including at least some of the geographical metadata associated with the captured video.

Abstract
Digital watermarking technology is used in conjunction with compressed video captured from aerial, unmanned apparatus, such as satellites and aircraft. One implementation includes a method of capturing video depicting at least a portion of the earth'"'"'s surface, the video captured by an aerial, unmanned apparatus; compressing the captured video; and hiding a first digital watermark in the compressed captured video through alterations to data representing the compressed video. The first digital watermark is generally imperceptible to a human observer of the video. And the digital watermark has a plural-bit payload including at least geographical metadata associated with the captured video. Other implementations are also provided.

19. A method comprising:
-
capturing video depicting at least a portion of the earth'"'"'s surface, the video captured by an aerial, unmanned apparatus;
compressing the captured video;
hiding first digital watermarking in the compressed captured video through alterations to data representing the compressed video, wherein the first digital watermarking is generally imperceptible to a human observer of the video, and wherein the first digital watermarking comprises at least a first plural-bit payload including at least first geographical metadata associated with the captured video;
hiding second digital watermarking in the compressed captured video through alterations to data representing the compressed video, wherein the second digital watermarking is generally imperceptible to a human observer of the video, and wherein the second digital watermarking comprises at least a second plural-bit payload including at least second, different geographical metadata associated with the captured video. - View Dependent Claims (20, 21, 22, 23)
