摘要

To ensure secure digital content delivery, MPEG has dedicated significant effort to DRM (Digital Rights Management) issues. The IPMP (Intellectual Property Management and Protection) components, the fourth part of the new MPEG standard project - MPEG-21 (Multimedia Framework) is one of the most important parts of this standardization activity. It defines an interoperable framework for IPMP. Fairly soon after MPEG-4, with its IPMP hooks became an International Standard, MPEG decided to start a new project named "MPEG-4 IPMP Extensions" on more interoperable IPMP systems and tools. The project includes standardized ways of retrieving IPMP tools from remote locations, standardized messages exchanged among IPMP tools and the terminal. It also addresses authentication of IPMP tools, and has provisions for integrating Rights Expressions according to the Rights Data Dictionary and the Rights Expression Language. After MPEG-2/4 IPMP standardization work is finished, efforts are currently ongoing to define the similar mechanism for the management and protection of intellectual property in the various parts of the MPEG-21 standard currently under development. The present paper describes the technologies that are now included in MPEG-21 IPMP Components Committee Draft to effectively manage and protect the digital content with the flexible IPMP scheme, which specifies how protection is applied to Digital Items and facilitates the exchange of governed content declared by a standard constructor MPEG-21 DID (Digital Item Declaration) between MPEG-21 Peers.
