Abstract :
In this paper, a DRM bridge concept is proposed and the modular framework of it is designed. In DRM bridge framework, UCON is used to build a rights expression original language, and language mapping tables are used to achieve the equivalent exchange between different REL standards. Besides a encryption/decryption library and a content format module are used to achieve the non-banding of DRM systems and its content format.
