Abstract

The invention provides a method and apparatus for providing content in a network having a network proxy arranged between a mobile terminal and a content provider. The method features a step of adapting or transforming the content in the network proxy based on one or more digital rights issued by the owner of the content. The network proxy includes an adaption policy module that receives the digital rights and provides an adaption policy; and an adaption engine module that receives the adaption policy and the content from the content provider, and provides adapted content to the terminal. In operation, the network proxy uses the digital rights to determine an optimal adaptation policy and then uses that to transform the content.

2. A method according to claim 1, wherein the digital rights include privileges/rights for adapting the content, restrictions/constraints under which the adaptation/transformation procedure of the content takes place, or a combination thereof.

3. A method according to claim 2, wherein the privileges/rights are absolute conditions for adapting the content.

4. A method according to claim 2, wherein the restrictions/constraints are boundary conditions for adapting the content.

5. A method according to claim 1, wherein the content provider is the owner of the content.

6. A method according to claim 1, wherein the network proxy uses the digital rights to determine an optimal adaptation policy and then uses that to transform the content.

7. A method according to claim 1, wherein the content provider has the responsibility of ensuring the integrity of the content is not lost in the adaptation process.

8. A method according to claim 1, wherein the owner issues the digital rights using any rights expression language (REL).

9. A method according to claim 8, wherein the rights expression language has a permission element for adapting the content, which can be executed/used in combination with already existing permission elements or any other permission elements that might emerge in the future.

10. A method according to claim 8, wherein the rights expression language has digital rights elements including an adapt element for providing a digital right in the form of a constraint on adapting the content.

11. A method according to claim 8, wherein the rights expression language has digital rights elements including a constraint element for providing a digital right with respect to either a color, size, format, layout or quality in relation to adapting the content, or a combination thereof.

12. A method according to claim 8, wherein the rights expression language has digital rights elements including a color element for providing a digital right in relation to a color of the content.

13. A method according to claim 8, wherein the rights expression language has digital rights elements including a size element for providing a digital right in relation to a size of the content.

14. A method according to claim 8, wherein the rights expression language has digital rights elements including a layout element for providing a digital right in relation to a layout of the content.

15. A method according to claim 8, wherein the rights expression language has digital rights elements including a reformat element for providing a digital right in relation to a reformatting of the content.

48. A method according to claim 1, wherein the method further comprises implementing the step of the method via a computer program running in a processing means in a network server.

49. A computer program product with a program code, which program code is stored on a machine readable carrier, for carrying out the steps according to claim 1 when the computer program is run in a processing means in a network server.

50. A method according to claim 1, wherein the content includes person-to-person, application-to-person and general Web or WAP browsing content.

16. A network having a network proxy arranged between a mobile terminal and a content provider for providing content characterized in that

the network proxy adapts or transforms the content based on one or more digital rights issued by the owner of the content.

17. A network according to claim 16, wherein the digital rights include privileges/rights for adapting the content, restrictions/constraints under which the adaptation/transformation procedure of the content takes place, or a combination thereof.

18. A network according to claim 17, wherein the privileges/rights are absolute conditions for adapting the content.

19. A network according to claim 17, wherein the restrictions/constraints are boundary conditions for adapting the content.

20. A network according to claim 16, wherein the content provider is the owner of the content.

21. A network according to claim 16, wherein the network proxy uses the digital rights to determine an optimal adaptation policy and then uses that to transform the content.

22. A network according to claim 16, wherein the content provider has the responsibility of ensuring the integrity of the content is not lost in the adaptation process.

23. A network according to claim 16, wherein the owner issues the digital rights using any rights expression language (REL).

24. A network according to claim 23, wherein the rights expression language has a permission element for adapting the content, which can be executed/used in combination with already existing permission elements or any other permission elements that might emerge in the future.

25. A network according to claim 23, wherein the rights expression language has digital rights elements including an adapt element for providing a digital right in the form of a constraint on adapting the content.

26. A network according to claim 23, wherein the rights expression language has digital rights elements including a constraint element for providing a digital right with respect to either a color, size, format, layout or quality in relation to adapting the content, or a combination thereof.
