Watermarking to set video usage permissions
A digital watermark in video includes a plural-bit payload that sets different permissions governing usage of the video. One bit, for example, may flag whether fast-forwarding of the video is permitted. Another may flag whether storage in non-encrypted form is permitted. A compliant video appliance governs its actions in accordance with such flag data provided by a video watermark detector.
1. A method comprising:
detecting, at a consumer device, auxiliary data conveyed with video;
governing a use of the video in accordance with one or more usage rules indicated by the auxiliary data;
inferring a subject of potential interest to a user by reference to behavior of the user;
processing the video to discern identification data corresponding thereto, wherein the processing comprises sensing a first in-band video watermark in the video, wherein the first in-band video watermark comprises the identification data, and wherein the first in-band video watermark is repeated continuously throughout the video;
by reference to the discerned identification data, determining whether the video corresponds to the subject of potential interest to the user;
taking an action based at least in part upon the determination, wherein taking an action comprises recording the video;
detecting an absence of the first in-band video watermark for a pre-determined interval; and
terminating the recording of the video based upon the detecting of the absence of the first in-band video watermark.
2. The method of claim 1 , wherein detecting comprises sensing a second in-band video watermark data in the video.
3. The method of claim 1 , wherein governing comprises, if the second watermark data includes a first flag, permitting storage of the video only on a first type of medium, and if the second watermark does not include the first flag, not limiting storage of the video to the first type of medium.
4. The method of claim 1 , wherein inferring comprises inferring a subject of potential user interest by reference to on-line activities of the user.
5. The method of claim 1 , wherein inferring comprises inferring a subject of potential user interest by reference to on-line resources to which the user links.
6. The method of claim 1 , wherein taking an action comprises making an entry about the video in a content listing data structure presented to the user.
7. The method of claim 6 , wherein the content listing data structure comprises a personal video record table of contents.
8. A non-transitory computer-readable medium having instructions stored thereon that, if executed by a computing device, cause the computing device to perform operations comprising:
detecting auxiliary data conveyed with video;
governing a use of the video in accordance with one or more usage rules indicated by the auxiliary data;
inferring a subject of potential interest to a user by reference to behavior of the user;
processing the video to discern identification data corresponding thereto, wherein the processing comprises sensing a first in-band video watermark in the video, wherein the first in-band video watermark comprises the identification data, and wherein the first in-band video watermark is repeated continuously throughout the video;
by reference to the discerned identification data, determining whether the video corresponds to the subject of potential interest to the user;
taking an action based at least in part upon the determination, wherein taking an action comprises recording the video;
detecting an absence of the first in-band video watermark for a pre-determined interval; and
terminating the recording of the video based upon the detecting of the absence of the first in-band video watermark.
9. The non-transitory computer-readable medium of claim 8 , wherein the detecting comprises sensing a second in-band video watermark data in the video.
10. The non-transitory computer-readable medium of claim 8 , wherein the governing comprises, if the second watermark data includes a first flag, permitting storage of the video only on a first type of medium, and if the second watermark does not include the first flag, not limiting storage of the video to the first type of medium.
11. The non-transitory computer-readable medium of claim 8 , wherein inferring comprises inferring a subject of potential user interest by reference to on-line activities of the user.
12. The non-transitory computer-readable medium of claim 8 , wherein inferring comprises inferring a subject of potential user interest by reference to on-line resources to which the user links.
13. The non-transitory computer-readable medium of claim 8 , wherein taking an action comprises making an entry about the video in a content listing data structure presented to the user.
14. The non-transitory computer-readable medium of claim 13 , wherein the content listing data structure comprises a personal video recorder table of contents.
15. An apparatus comprising:
a processor configured to:
detect auxiliary data conveyed with video;
govern a use of the video in accordance with one or more usage rules indicated by the auxiliary data;
infer a subject of potential interest to a user by reference to behavior of the user;
process the video to discern identification data corresponding thereto, wherein the processing comprises sensing a first in-band video watermark in the video, wherein the first in-band video watermark comprises the identification data, and wherein the first in-band video watermark is repeated continuously throughout the video;
by reference to the discerned identification data, determine whether the video corresponds to the subject of potential interest to the user;
take an action based at least in part upon the determination, wherein taking an action comprises recording the video;
detecting an absence of the first in-band video watermark for a pre-determined interval; and
terminating the recording of the video based upon the detecting of the absence of the first in-band video watermark.
