COLLISION PREVENTION METHOD BETWEEN HETEROGENEOUS DRM CLIENTS BY BOTH RUNNING INDIVIDUAL PROCESS AND SWITCHING MECHANISM

摘要

PURPOSE: A collision prevention method between heterogeneous DRM(Digital Rights Management) clients by using both a running individual process and a switching mechanism is provided to efficiently prevent a collision. CONSTITUTION: A process branch part(110) is inserted within a DRM client module. An environment for independently executing the process of the terminal is made by the sorts of the DRM. The independent process execution process is progressed when an access to a DRM content file is generated. The process branch portion determines the sorts of the DRM by inquiring the branch process information of the corresponding content.
