Method of providing interoperability between DRMs and DRM module thereof

摘要

A method of providing interoperability between DRMs(Digital Rights Managements) and a DRM module thereof are provided to enable a DRM processor to support various DRMs without analyzing the information of different kinds of DRMS which can be applied to contents in a device. At least one DRM tool(410) performs a DRM operation. When receiving a process enable query message that inquires whether or not a resource can be processed, DRM agents(420) check over whether or not the resource can be processed and responses to the DRM processor about the result. The DRM agents and the DRM tools are realized in an additional hardware or software module.
