Information technology — Multimedia framework (MPEG-21) — Part 4: Intellectual Property Management and Protection Components
ISO/IEC 21000-4:2006 specifies how to include Intellectual Property Management and Protection (IPMP) information and protected parts in a Digital Item. It provides a simple mechanism to include protected parts in the DID (ISO/IEC 21000-2) description of a digital item, and provides mechanisms for describing the governance over, and the tools used for the protected content. ISO/IEC 21000 (MPEG-21) defines an open framework for multimedia delivery and consumption, with both the content creator and content consumer as focal points. The vision for MPEG-21 is to define a multimedia framework to enable transparent and augmented use of multimedia resources across a wide range of networks and devices used by different communities. The basic architectural concept in MPEG-21 is the Digital Item. Digital Items are structured digital objects, including a standard representation and identification, and metadata. They are the basic unit of transaction in the MPEG-21 framework. Within ISO/IEC 21000-4:2006 this technology is described in three main sections: IPMP DIDL: ISO/IEC 21000-4:2006 provides an alternative normative representation for parts of Digital Items that require protection through IPMP governance. This representation is termed the IPMP Digital Item Declaration Language (IPMP DIDL), and defines governed XML elements corresponding to entities in the DID model (ISO/IEC 21000-2). IPMP Info Descriptor: The IPMPInfoDescriptor and its associated elements are used to communicate information about the IPMP governance and tools required for a Digital Item or its parts. IPMP General Info Descriptor: The IPMPGeneralInfoDescriptor and its associated elements are used to communicate general information relating to a complete Digital Item. The aim of ISO/IEC 21000-4:2006 is to allow controls on the flow and usage of Digital Items throughout their lifecycle. ISO/IEC 21000-4:2006 purposely does not specify protection measures, keys, key management, trust management, encryption algorithms, certification infrastructures or other components that would also be needed as part of a complete IPMP solution.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 21000-4 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,

Introduction
The appetite of end users for content and the accessibility of information is growing at an incredible pace.
Access devices with a wide range of terminal and network capabilities are becoming an integral part of end
users’ lives; furthermore, these devices are used in different locations and environments. As yet, users are not
sufficiently empowered with the necessary tools to deal efficiently with the intricacies of this new multimedia
usage environment.
The enabling of “ease of use” is becoming increasingly important as individuals produce more and more digital
media for personal use and for sharing among family and friends (as is evidenced by the large number of
amateur music, photo and media sharing web sites). These amateur “content providers” have many of the
same concerns as commercial content providers, including management of content, re-purposing of content
based on consumer/device capabilities, protection of rights, protection from unauthorized access/modification,
privacy protection for providers and consumers, etc.
Such developments provide new models for distributing and trading digital content electronically in addition to
existing business models for trading physical goods. Such new business models mean that the boundaries
between the delivery of audio sound (music and spoken word), accompanying artwork (graphics), text (lyrics),
video (visual) and synthetic spaces will become increasingly blurred. Indeed, it is becoming more and more
difficult to identify the different intellectual property rights that are associated with multimedia content. New
solutions are required to manage the access and delivery process of these different content types in an
integrated and harmonized way, entirely transparent to the user of multimedia services.
With this motivation, the ISO/IEC 21000 MPEG-21 Multimedia Framework aims to enable the transparent and
augmented use of multimedia resources across a wide range of networks and devices. This fourth part of
ISO/IEC 21000 aims to address the need for effective management and protection of intellectual property in
the Multimedia Framework over heterogeneous access and delivery infrastructures. It specifies components
for Intellectual Property Management and Protection (IPMP) applied to Digital Items (see ISO/IEC 21000-2) to
facilitate the exchange of governed content between peers.

Information technology — Multimedia framework (MPEG-21) —
Part 4:
Intellectual Property Management and Protection Components
1 Scope
This part of ISO/IEC 21000 specifies how to include IPMP information and protected parts of Digital Items in a
DIDL document. It purposely does not specify protection measures, keys, key management, trust
management, encryption algorithms, certification infrastructures or other components that would also be
needed as part of a complete IPMP solution.
The IPMP DIDL encapsulates and protects a part of the hierarchy of a Digital Item, and associates appropriate
identification and protection information with it. The description of IPMP governance and tools is required to
satisfy IPMP for a Digital Item or its parts to be accessed.
