摘要： A system and method of protecting digital media contents, which maintain compatibility with an existing system and block any attempt to illegally use the digital media contents having various formats, and which reduce a system load and maximize a possibility of reusing the digital media contents. The system includes a packager for analyzing a format of contents and encoding at least a portion of a data region located in a payload of the contents, and for generating encoded contents by inserting encoding information including at least one of an encoding key value and contents information into the contents; and a digital rights management (DRM) server for receiving a request for a license and the encoding information from an external device which receives the encoded contents, for confirming the encoding information and then generating a license which is used to decode the encoded contents, and for providing the generated license to the external device.
