Watermark and fingerprint systems for media
A number of novel watermarking applications, and improvements to watermarking methods, are disclosed. Included are techniques for selectively incorporating promotional messages into rendered video content, monitoring whether promotional messages are rendered or skipped, permitting payment for content upon rendering rather than receipt, controlling rendering of video to include or omit adult-themed sections, confirming a person's age by reference to a watermarked identification document, and watermarking digital cinema projections.
1. A method of video content delivery comprising:
receiving from an electronic communication network, using one or more electronic processors, entertainment video content comprising at least one watermark;
receiving from the electronic communication network a promotional message that is separate from the entertainment video content;
detecting a watermark calibration signal using a hardware decoder in the one or more electronic processors, to locate the at least one watermark in the entertainment video content;
selecting, using the one or more electronic processors, the promotional message based upon at least the located at least one watermark; and
embedding, using the one or more electronic processors, the selected promotional message into the entertainment video content at a location based upon at least the at least one watermark.
2. A system comprising:
one or more electronic processors configured to:
receive video entertainment content from an electronic communication network, wherein the video entertainment content comprises at least one watermark;
receive from the electronic communication network a promotional message that is separate from the entertainment video content;
detecting a watermark calibration signal with a hardware decoder to locate the at least one watermark in the entertainment video content;
select the promotional message based at least upon the located at least one watermark; and
embed the selected promotional message into the entertainment video content at a location based at least upon the at least one watermark.
3. The system of claim 2 , wherein the one or more electronic processors are further configured to determine a reward for rendering the promotional message, wherein the reward comprises a discount for a product promoted by the promotional message.
4. The system of claim 2 , wherein the one or more electronic processors are further configured to display an on-screen signal with the entertainment content to indicate that an opportunity exists for the user to earn credit by viewing additional information.
5. The method of claim 1 , wherein the selecting the promotional message based at least upon the located at least one watermark comprises selecting the promotional message based at least upon a time.
6. The method of claim 1 , further comprising:
rendering at least a portion of the entertainment video content;
rendering the promotional message;
determining if the promotional message was completely rendered; and
charging for the rendering of the at least a portion of the entertainment video content based at least upon the determining if the promotional message was completely rendered.
7. The method of claim 1 , wherein the entertainment video content comprises a plurality of watermarks including the at least one watermark, wherein the sensing the at least one watermark comprises sensing two or more of the plurality of watermarks, wherein the method further comprises:
determining to insert the promotional message based at least upon a number of sensed watermarks.
8. The method of claim 1 , wherein the selecting the promotional message based at least upon the sensed at least one watermark comprises selecting a personalized promotional message.
9. The method of claim 1 , wherein the at least one watermark indicates a programming subject of the entertainment video content, and wherein the selecting the promotional message based at least upon the sensed at least one watermark comprises selecting the promotional message based at least upon the indicated programming subject.
10. The method of claim 1 , further comprising displaying an on-screen signal with the entertainment content to indicate that an opportunity exists for the user to earn credit by viewing additional information.
11. The system of claim 2 , wherein the one or more electronic processors are further configured to select the promotional message based at least upon a time.
12. The system of claim 2 , wherein the one or more electronic processors are further configured to:
render at least a portion of the entertainment video content;
render the promotional message;
determine if the promotional message was completely rendered; and
charge for the rendering of the at least a portion of the entertainment video content based at least upon the determining if the promotional message was completely rendered.
13. The system of claim 2 , wherein the entertainment video content comprises a plurality of watermarks including the at least one watermark, wherein the one or more electronic processors are further configured to:
sense two or more of the plurality of watermarks; and
determine to insert the promotional message based upon at least a number of sensed watermarks.
14. The system of claim 2 , wherein the promotional message comprises a personalized promotional message.
15. The system of claim 2 , wherein the at least one watermark indicates a programming subject of the entertainment video content, and wherein the one or more electronic processors are further configured to determine the promotional message based in part on the programming subject.
16. A non-transitory computer-readable medium, having instructions stored thereon, the instructions comprising:
instructions to receive entertainment video content from an electronic communication network, wherein the entertainment video content comprises at least one watermark;
instructions to receive, from the electronic communication network, a promotional message that is separate from the entertainment video content;
instructions to detect a watermark calibration signal using a hardware decoder, in the at least one watermark in the entertainment video content;
instructions to select the promotional message based upon at least the at least one watermark; and
instructions to embed the promotional message into the entertainment video content at a location based upon at least the at least one watermark.
17. The non-transitory computer-readable medium of claim 16 , wherein the instructions to select the promotional message based upon at least the sensed at least one watermark comprises instructions to select the promotional message based upon at least a time.
18. The non-transitory computer-readable medium of claim 16 , further comprising:
instructions to render at least a portion of the entertainment video content;
instructions to render the promotional message;
instructions to determine if the promotional message was completely rendered; and
instructions to charge for the rendering of the at least a portion of the entertainment video content based at least upon the determining if the promotional message was completely rendered.
19. The non-transitory computer-readable medium of claim 16 , wherein the entertainment video content comprises a plurality of watermarks including the at least one watermark, wherein the sensing the at least one watermark comprises sensing two or more of the plurality of watermarks, wherein the instructions further comprises:
instructions to determine to insert the promotional message based upon at least a number of sensed watermarks.
20. The non-transitory computer-readable medium of claim 16 , wherein the at least one watermark indicates a programming subject of the entertainment video content, and wherein the instructions to select the promotional message based upon at least the sensed at least one watermark comprises instructions to select the promotional message based upon at least the indicated programming subject.
