Abstract

Content browsers determine and enforce the digital rights of one piece of multimedia content to embed another. Such digital rights are encoded as data inside the content, as data in associated files, or managed by digital rights network services. In one example, Web browsers determine digital rights by comparing URLs of the embedding and embedded content, potentially with the help of digital rights Web services.

Claims

1. A computer-implemented method for provision and use of digital rights data for embedded data over networked systems, said method comprising:

a. preparing to render “

outer”

content that contains a reference to “

inner”

content, with the semantics of rendering the inner content as a sub-part of the outer content;

b. comparison of outer content metadata with inner content metadata to see if the outer content has the digital rights to render the inner content as a sub-part;

c. based on the comparison, rendering the inner content as a sub-part of the outer content, or not.

2. The method according to claim 1 wherein the networked system is based on Internet technologies including Web browsers, Web servers, Uniform Resource Locators/Indicators (URLs/URLs) and the Hypertext Transport (HTTP) protocol, content is referenced by URL, and content metadata includes the referencing URLs.

3. The method according to claim 1 wherein inner content digital rights data may be encoded into the inner content itself, and content browsers use this data to confirm digital rights between content metadata.

4. The method according to claim 1 wherein the comparison of content metadata for the purpose of determining digital rights is performed by a network service at the request of a content browser.

5. The method according to claim 1 wherein if said comparison fails to confirm digital rights, the content browser displays information about how to acquire the digital rights to embed the inner content in the outer content.

6. The method according to claim 4 wherein if the said network service reports a lack of digital rights to the content browser, that it may also respond with information on how to acquire the necessary digital rights.

7. The method according to claim 2 wherein digital rights are encoded as a relation between inner and outer content URLs.

8. The method according to claim 7 wherein said relation between URLs is implemented as white-list and black-list specifications of URL patterns.

9. The method according to claim 2 wherein digital rights management functionality is built-in to a Web browser.

10. The method according to claim 2 wherein digital rights management functionality is part of a Web browser media-handler plug-in.

11. The method according to claim 4 wherein said network service'"'"'s location is derived from the inner content location.

12. The method according to claim 11 wherein said locations are indicated by URLs.

13. The method according to claim 1 wherein said inner and outer content reside as separate networked content owned and provided by separate entities.

14. The method according to claim 1 wherein said comparison also checks an expiration date and/or time to determine digital rights.

15. The method according to claim 1 wherein said comparison also checks the number of times the inner content is embedded in the outer content.
