First Claim
Patent Images
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.

Abstract
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.
