Abstract

Systems and methods for controlling the use of audio, video and audiovisual content are provided. A data structure includes content usage rights for multiple release windows. The usage rights may be encoded in the content or otherwise bound to the content. Playback devices are configured to access the appropriate usage rights and control usage in accordance with the usage rights.

First claim

I claim:

1. A method comprising:
receiving, by a computing device, digital content;
determining, by the computing device, first data indicating first usage rights for the digital content and indicating a first content release window that controls when the first usage rights are applied, wherein the first usage rights control how the digital content is used during the first content release window;
determining, by the computing device, second data indicating second usage rights for the digital content and indicating a second content release window that controls when the second usage rights are applied, wherein the second usage rights control how the digital content is used during the second content release window, the second usage rights being different from the first usage rights and the second content release window being different from the first content release window; and
prior to the first content release window and the second content release window, encoding, by the computing device, the digital content with a single data structure, wherein the single data structure indicates the first usage rights, the second usage rights, the first content release window, and the second content release window, associates the first usage rights with the first content release window, and associates the second usage rights with the second content release window.

2. The method of claim 1 , further comprising:
determining, by the computing device, third usage rights for the digital content, wherein the third usage rights control how the digital content is used during a third content release window,
wherein the third usage rights are different from the first usage rights and the second usage rights,
wherein the third content release window is different from the second content release window and the first content release window, and
wherein the single data structure further indicates the third usage rights and the third content release window, and associates the third usage rights with the third content release window.

3. The method of claim 1 , wherein the encoding, by the computing device, the digital content with the single data structure comprises encoding, by the computing device comprising an encoder, the digital content with the single data structure that further indicates third usage rights that control how the digital content is used during a third content release window.

4. The method of claim 1 , further comprising encoding the digital content with additional data indicating third usage rights that control how the digital content is used during a third content release window.

5. The method of claim 1 ,
wherein the determining the first data comprises determining a first number of copies of the digital content allowed to be made during the first content release window, and
wherein the determining the second data comprises determining a second number of copies of the digital content allowed to be made during the second content release window.

6. The method of claim 1 ,
wherein the determining the first data comprises determining first copy control information for the digital content during the first content release window, and
wherein the determining the second data comprises determining second copy control information for the digital content during the second content release window.

7. The method of claim 1 ,
wherein the determining the first data comprises determining first information indicating through which outputs the digital content is allowed to be output during the first content release window, and
wherein the determining the second data comprises determining second information indicating through which outputs the digital content is allowed to be output during the second content release window.

8. The method of claim 1 ,
wherein the determining the first data comprises determining whether recording of the digital content is allowed to be performed during the first content release window, and
wherein the determining the second data comprises determining whether recording of the digital content is allowed to be performed during the second content release window.

9. The method of claim 1 ,
wherein the determining the first data comprises determining whether the digital content is allowed to be viewed on a particular type of device during the first content release window, and
wherein the determining the second data comprises determining whether the digital content is allowed to be viewed on the particular type of device during the second content release window.

10. The method of claim 1 ,
wherein the determining the first data comprises determining whether the digital content is allowed to be viewed on a portable device during the first content release window, and
wherein the determining the second data comprises determining whether the digital content is allowed to be viewed on the portable device during the second content release window.

11. The method of claim 1 , wherein the single data structure comprises an extensible markup language (XML) file.

12. The method of claim 1 , wherein the second content release window overlaps in time with the first content release window.

13. A method comprising:
receiving, by a computing device, first data comprising first release window information and first usage rights information associated with the first release window information, wherein the first release window information indicates a first content release window that controls when the first usage rights information is used and that corresponds to a first period of time during which content is distributed through a first distribution channel, and wherein the first usage rights information controls how the content is used during the first content release window;
receiving, by the computing device, second data comprising second release window information and second usage rights information associated with the second release window information, wherein the second release window information indicates a second content release window that controls when the second usage rights information is used and that corresponds to a second period of time during which the content is distributed through a second distribution channel that is different from the first distribution channel, and wherein the second usage rights information controls how the content is used during the second content release window; and
prior to the first period of time and the second period of time, marking, by the computing device, the content with a file that comprises the first release window information, the first usage rights information, the second release window information, and the second usage rights information, that associates the first usage rights information with the first release window information, and that associates the second usage rights information with the second release window information.

14. The method of claim 13 , wherein the marking the content comprises watermarking the content with the first release window information, the first usage rights information, the second release window information, and the second usage rights information.

15. The method of claim 13 , wherein the marking the content comprises cryptographically binding the file to the content.

16. The method of claim 13 , further comprising:
digitally signing the content after marking the content.

17. The method of claim 13 , wherein the file comprises a pointer pointing to one of the first usage rights information and the second usage rights information.

18. The method of claim 13 , wherein t
