Accounting Solutions in the AXMEDIS Project

A large part of models for digital rights management include methods for logging the information related to the actions performed by final users on the content and on the players. These actions can be associated with the exploitation of the rights granted in the license, and may include other activities such as eventual changes of preference, installations, certifications, etc. In this area, relevant models have been defined by MPEG-21, whose usage and some extensions are reported in this paper. This paper discusses the new functionalities enabled by the AXMEDIS architecture and solution in terms of interoperable content and DRM among different distribution channels in relationship with the tracking and accounting of actions performed on the content by the final users on the players and on authoring tools. AXMEDIS aims at creating an innovative technology framework for the automatic production, protection and distribution of digital cross-media contents over a range of different media channels, including PC (on the Internet), PDA, kiosks, mobile phones and i-TV (interactive-TV)
