Watermarking to set video usage permissions |
摘要 |
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. |
