APPARATUS AND METHOD OF EXECUTING DRM TOOL IN CONTENTS DEVICE FOR INTEROPERABLE DRM

摘要

A device for applying DRM(Digital Rights Management) to a contents execution terminal with interoperability and an operation method thereof are provided to enable a user to use the same contents in various devices without converting the contents by using an operation mechanism among a contents player, a DRM processor, a DRM agent, and a DRM tool library. A DRM processor(220) searches an applied DRM tool(230) from a terminal or an external server based on DRM tool information by receiving the DRM tool information, which includes a control point applying the DRM tool in contents, from a contents player(210). A DRM tool agent(231) is included in the searched DRM tool, and connects a library function for the DRM tool with the control point by receiving the DRM tool information from the DRM processor and loading a DRM tool library(232). The contents player decodes the DRM contents by applying the DRM tool again in a way which transfers the contents to the DRM tool agent by calling the DRM processor at the connected control point. The DRM tool agent determines whether the DRM tool is applicable to the contents based on the DRM tool information, authenticates and connects the library function with the control point when the DRM tool is applicable.
