Abstract

System renewability message data is transmitted to set top boxes, or other devices, using a transport protocol such as, for example, an Internet protocol-type data stream. In accordance with one embodiment, an Extensible Markup Language-type file is received via an Internet protocol-type transport stream. Data, which corresponds to the identities of devices that are unauthorized for the use of certain content, is selected from the Extensible Markup Language-type file. This data from the file is processed whereupon use of the content is prevented in accordance with the data.

Claims

1. A method comprising:

receiving an XML-type file via an IP-type transport stream;

selecting data from the XML-type file; and

preventing use of content in accordance with the data,

wherein the data corresponds to identities of one or more devices that are unauthorized for the use of the content.

2. The method of claim 1 wherein the XML-type file is a compressed file.

3. The method of claim 1 wherein the data includes a first value corresponding to a first attribute definition and to an identity of a provider of copy protection technology.

4. The method of claim 3 wherein the first value is registered with a central authority.

5. The method of claim 4 wherein the central authority comprises one of a Digital Video Broadcasting Project-type organization and a Society of Motion Picture and Television Engineers Registration Authority-type organization.

6. The method of claim 3 wherein the data further includes a second value corresponding to a second attribute definition and to a version of the data.

7. The method of claim 1 wherein the XML-type file is an XML instance file having a format that is generally consistent with an XML schema.

8. The method of claim 7 wherein the data is comprised of a first data block and a second data block, wherein the first data block includes data provided by a first provider of copy protection technology, wherein the second data block includes data provided by a second provider of copy protection technology, and wherein the first provider of copy protection technology is different than the second provider of copy protection technology.

9. The method of claim 7 wherein the data is comprised of at least one data block,

wherein the XML schema includes a first element, a second element and a third element,

wherein the first element is for containing the data block, wherein the data block is carried as an instance of a first metadata element,

wherein the second element includes at least one instance of the first metadata element, wherein the instance of the first metadata element is defined according to the third element, and

wherein the third element defines a data structure for the data block.

10. The method of claim 9 wherein the third element has a first attribute definition corresponding to a first value, wherein the first value corresponds to an identity of a copy protection provider.

11. The method of claim 10 wherein the third element further has a second attribute definition corresponding to a second value, wherein the second value corresponds to a version of the data block.

12. An article of manufacture for preventing the use of content by a plurality of devices that are unauthorized for the use of the content and that have identities, the article of manufacture being for use by another device having a processing unit, the article of manufacture comprising:

at least one computer usable media including at least one computer program embedded therein, the at least one computer program being adapted to cause the other device to perform;

receiving an XML-type file via an IP-type transport stream;

selecting data from the XML-type file; and

preventing use of content in accordance with the data,

wherein the data corresponds to the identities of the plurality of devices.

13. The article of manufacture of claim 12 wherein the data includes a first value corresponding to a first attribute definition and to an identity of a provider of copy protection technology.

14. The article of manufacture of claim 13 wherein the first value is registered with a central authority.

15. The article of manufacture of claim 14 wherein the central authority comprises one of a Digital Video Broadcasting Project-type organization and a Society of Motion Picture and Television Engineers Registration Authority-type organization.

16. The article of manufacture of claim 13 wherein the data further includes a second value corresponding to a second attribute definition and to a version of the data.

17. The article of manufacture of claim 12 wherein the XML-type file is an XML instance file having a format that is generally consistent with an XML schema.

18. The article of manufacture of claim 17 wherein the data is comprised of a first data block and a second data block, wherein the first data block includes data provided by a first provider of copy protection technology, wherein the second data block includes data provided by a second provider of copy protection technology, and wherein the first provider of copy protection technology is different than the second provider of copy protection technology.

19. The article of manufacture of claim 17 wherein the data is comprised of at least one data block,

wherein the XML schema includes a first element, a second element and a third element,

wherein the first element is for containing the data block, wherein the data block is carried as an instance of a first metadata element,

wherein the second element includes at least one instance of the first metadata element, wherein the instance of the first metadata element is defined according to the third element, and

wherein the third element defines a data structure for the data block.

20. The article of manufacture of claim 19 wherein the third element has a first attribute definition corresponding to a first value, wherein the first value corresponds to an identity of a copy protection provider.

21. The article of manufacture of claim 20 wherein the third element further has a second attribute definition corresponding to a second value, wherein the second value corresponds to a version of the data block.

22. A system for preventing the use of content by a plurality of devices that are unauthorized for the use of the content and that have identities, the system comprising:

another device having a processing unit capable of executing software routines, and

programming logic executed by the processing unit, wherein the programming logic comprises;

means for receiving an XML instance file via an IP-type transport stream,

wherein the XML instance file has a format that is generally consistent with an XML schema;

means for selecting data from the XML instance file; and

means for preventing the use of the content in accordance with the data,

wherein the data corresponds to the identities of the plurality of devices.

23. The system of claim 22 wherein the data is comprised of at least one data block,

wherein the XML schema includes a first element, a second element and a third element,

wherein the first element is for containing the data block, wherein the data block is carried as an instance of a first metadata element,

wherein the second element includes at least one instance of the first metadata element, wherein the instance of the first metadata element is defined according to the third element, and

wherein the third element defines a data structure for the data block.
