Abstract

Method, system and computer program product for updating pre-existing region-dependent software within multiple regions via a common software update without affecting the region-dependent nature of the software. The technique includes extracting region information from pre-existing region-dependent software on a user system; loading the non-functional software update onto the user system, the non-functional update being a common software update for the multiple regions; and merging the region information extracted from the pre-existing region-dependent software with the non-functional software update loaded onto the user system to produce a functional, updated region-dependent software on the user system. In one example, the user system comprises a digital video disc (DVD) PC system, and the distribution network is the internet. An activation module accompanies the common software update and accomplishes the extracting, loading and merging steps.

Claims

1. A method for updating pre-existing region-dependent software, said method comprising:

extracting region information from the pre-existing region-dependent software located within a user system;

loading a non-functional software update onto the user system, said update comprising a common non-functional software update for multiple regions; and

merging the region information extracted from the pre-existing region-dependent software with the non-functional software update loaded onto the user system to produce functional, updated region-dependent software.

2. The method of claim 1, wherein said pre-existing region-dependent software comprises a pre-existing copy protect module and said non-functional software update comprises an updated copy protect module.

3. The method of claim 1, further comprising providing said non-functional software update to multiple regions.

4. The method of claim 3, wherein said providing includes placing said common non-functional software update on a network, and wherein multiple user systems are coupled to said network within said multiple regions.

5. The method of claim 4, wherein said providing further comprises providing an activation module to said multiple regions in association with said non-functional software update, said activation module accomplishing said extracting, said loading, and said merging.

6. The method of claim 1, further comprising prior to said extracting, verifying presence of said pre-existing region-dependent software on said user system.

7. The method of claim 6, further comprising prior to said extracting, determining whether the pre-existing region-dependent software on said user system is valid, and if invalid, discontinuing said extracting, said loading and said merging.

8. The method of claim 1, further comprising removing the pre-existing region-dependent software from the user system subsequent to producing said functional, updated region-dependent software.

9. The method of claim 1, wherein said user system comprises a digital video disc (DVD) PC system, and wherein said loading comprises loading said non-functional software update onto the DVD PC system.

10. A system for updating pre-existing region-dependent software, said system comprising:

means for extracting region information from the pre-existing region-dependent software located within a user system;

means for loading a non-functional software update onto the user system, said update comprising a common non-functional software update for multiple regions; and

means for merging the region information extracted from the pre-existing region-dependent software with the non-functional software update loaded onto the user system to produce functional, updated region-dependent software.

11. The system of claim 10, wherein said pre-existing region-dependent software comprises a pre-existing copy protect module and said non-functional software update comprises an updated copy protect module.

12. The system of claim 10, further comprising means for providing said non-functional software update to multiple regions, said means for providing comprising means for placing said non-functional software update on a network, and wherein multiple user systems are coupled to said network within said multiple regions.

13. The system of claim 12, wherein said means for providing further comprises means for providing an activation module to said multiple regions in association with said non-functional software update, said activation module comprising said means for extracting, means for loading, and means for merging.

14. The system of claim 10, further comprising means for verifying presence of said pre-existing region-dependent software on said user system prior to extracting of said regional information.

15. The system of claim 14, further comprising means for determining prior to said extracting whether the pre-existing region-dependent software on said system is valid, and if invalid, means for discontinuing processing of said means for extracting, means for loading and means for merging.

16. The system of claim 10, further comprising means for removing the pre-existing region-dependent software from the user system subsequent to producing said functional, updated region-dependent software.

17. The system of claim 10, wherein said user system comprises a digital video disc (DVD) PC system.

18. A computer program product comprising a computer usable medium having computer readable program code means therein for use in updating pre-existing region-dependent software, said computer readable program code means in said computer program product comprising:

computer readable program code means for causing a computer to affect extracting region information from the pre-existing region-dependent software located within a user system;

computer readable program code means for causing a computer to affect loading a non-functional software update onto the user system, said update comprising a common non-functional software update for multiple regions; and

computer readable program code means for causing a computer to affect merging the region information extracted from the pre-existing region-dependent software with the non-functional software update loaded onto the user system to produce functional, updated region-dependent software.

19. The computer readable program code means of claim 18, wherein said pre-existing region-dependent software comprises a pre-existing copy protect module and said non-functional software update comprises an updated copy protect module.

20. The computer readable program code means of claim 18, further comprising computer readable program code means for causing a computer to affect providing said non-functional software update to multiple regions across a network, and wherein multiple user systems are coupled to said network within said multiple regions.

21. The computer readable program code means of claim 20, wherein said computer readable program code means for causing a computer to affect providing further comprises computer readable program code means for causing a computer to affect providing an activation module to said multiple regions in association with said non-functional software update, said activation module comprising said computer readable program code means for causing a computer to affect said extracting, said loading and said merging.

22. The computer readable program code means of claim 18, further comprising computer readable program code means for verifying presence of said pre-existing region-dependent software on said user system prior to extracting of said regional information.

23. The computer readable program code means of claim 22, further comprising computer readable program code means for causing a computer to affect determining whether the pre-existing region-dependent software on said user system is valid, and if invalid, for discontinuing said extracting, said loading and said merging.

24. The computer readable program code means of claim 18, wherein said user system comprises a digital video disc (DVD) PC system.
