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.
