Title: Liaison Statement regarding Digital Rights Standards work in the Internet Research Task Force

WG11 thanks you for the information on the impending formation of the IRTF research group on digital rights management. MPEG’s history in what we call Intellectual Property Management and Protection (IPMP) goes back to 1994, and we are moving from standardised identification of IP towards more interoperability in management and protection. See the enclosed ‘Intellectual Property Management and Protection in MPEG Standards’ (ISO/IEC JTC1 SC29 WG11 N3943) for an overview of that work.

Currently, MPEG works on the following IPMP-related issues:

• Extending the MPEG-4 IPMP ‘hooks’ (interfaces to proprietary systems) towards more interoperable solutions. We envisage issuing a public Committee Draft in July.
• In the context of the MPEG-7 standard, we develop technologies that address the authentication and protection of metadata. We expect this to form an integral part of version 1 of the MPEG-7 Standard, which is to be finalized by July this year.
• Technology for uniquely identifying content (the MPEG-21 Digital Item Identification and Description mechanism), scheduled for completion in March 2002.
• Also in the context in of MPEG-21, we have issued a first draft of Requirements for a Rights Expression Language and Rights Data Dictionary. See WG 11 N 4044 enclosed. The Call for Requirements has been extended to June 1^st, see enclosed. We would welcome your input to these requirements, and we will be happy to cooperate on the development of both the requirements and the Language/Dictionary. We envisage issuing a Call for Proposals in July 2001.
