National bodies that are members

23、 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 organi

24、zations, 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

25、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 % o

26、f the national bodies casting a vote. ISO/IEC 21000-3 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information. ISO/IEC 21000 consists of the following parts, under the general title Informati

27、on technology Multimedia framework (MPEG-21): Part 1: Vision, Technologies and Strategy Part 2: Digital Item Declaration Part 3: Digital Item Identification Part 4: Intellectual Property Management and Protection Part 5: Rights Expression Language Part 6: Rights Data Dictionary Part 7: Digital Item

29、ISO/IEC 2003 All rights reservedExecutive Summary for MPEG-21 Today, many elements exist to build an infrastructure for the delivery and consumption of multimedia content. There is, however, no “big picture“ to describe how these elements, either in existence or under development, relate to each oth

30、er. The aim for MPEG-21 is to describe how these various elements fit together. Where gaps exist, MPEG-21 will recommend which new standards are required. ISO/IEC JTC 1/SC 29/WG 11 (MPEG) will then develop new standards as appropriate while other relevant standards may be developed by other bodies.

31、These specifications will be integrated into the multimedia framework through collaboration between MPEG and these bodies. The result is an open framework for multimedia delivery and consumption, with both the content creator and content consumer as focal points. This open framework provides content

32、 creators and service providers with equal opportunities in the MPEG-21 enabled open market. This will also be to the benefit of the content consumer providing them access to a large variety of content in an interoperable manner. The vision for MPEG-21 is to define a multimedia framework to enable t

33、ransparent and augmented use of multimedia resources across a wide range of networks and devices used by different communities. This third part of MPEG-21 (ISO/IEC 21000-3) specifies how Digital Items (see ISO/IEC 21000-2) and parts and collections thereof can be uniquely identified. Copyright Ameri

35、gital Item Identification 1 Scope This third part of MPEG-21 (ISO/IEC 21000-3), entitled Digital Item Identification (DII), specifies How to uniquely identify Digital Items (and parts thereof); How to uniquely identify IP related to the Digital Items (and parts thereof), for example abstractions; Ho

36、w to uniquely identify Description Schemes; The relationship between Digital Items (and parts thereof) and existing identification systems. Annex C contains a list of relevant identification systems. This is not an exhaustive list and is subject to change over time; The relationship between Digital

37、Items (and parts thereof) and relevant description schemes. Annex C contains a list of relevant description schemes. This is not an exhaustive list and is subject to change over time. ISO/IEC 21000-3 specification does not specify: New identification systems for the content elements for which identi

38、fication and description schemes already exist and are in use (e.g., ISO/IEC 21000-3 does not attempt to replace the ISRC, as defined in ISO 3901, for sound recordings; Normative description schemes for describing content. 1.1 Organisation of the Document This specification contains five Clauses and

39、 four Annexes: The remainder of this Clause 1 contains an overview of MPEG-21 Digital Items and the relation between parts 2 and 3 of ISO/IEC 21000. Clauses 2 and 3 contain normative references and a list of applicable terms and definitions. Clause 4 specifies how to uniquely identify Digital Items,

40、 how to associate related identifiers with Digital Items, how to identify different types of Digital Items. Clause 0 then specifies how to associate metadata with Digital Items by using description scheme identifiers. The normative Annex A contains criteria that need to be fulfilled by a registratio

41、n authority that is required for the identification of Digital Items and their parts as specified in ISO/IEC 21000-3. Annex B contains an informative example of how to resolve a unique identifier to appropriate metadata. Annex C contains an informative list of existing identification schemes that ca

42、n be used by this specification. Finally, Annex D contains information of patent statements relating to this specification.

43、C 21000-3:2003(E) 2 ISO/IEC 2003 All rights reserved1.2 Introduction to Digital Items Within any system (such as MPEG-21) that proposes to facilitate a wide range of actions involving “Digital Items”, there is a need for a very precise description for defining exactly what constitutes such an “item”

44、. Clearly there are many kinds of content, and probably just as many possible ways of describing it to reflect its context of use. This presents a strong challenge to lay out a powerful and flexible model for Digital Items which can accommodate the myriad forms that content can take (and the new for

45、ms it will assume in the future). Such a model is only truly useful if it yields a format that can be used to represent any Digital Items defined within the model unambiguously and communicate them, and information about them, successfully. The Digital Item Declaration specification (ISO/IEC 21000-2

46、) provides such flexibility for representing Digital Items. 1.3 Example of a Digital Item This sub-clause provides a simple example of a Digital Item. More complex examples can be found in ISO/IEC 21000-2. This example uses ISO/IEC 21000 to create an “MPEG-21 Music Album“ comprising a series of reso

47、urces: Three audio files (coded in MPEG-2 AAC1), representing the “tracks“ that form the basis of the album; Two text files (in Unicode2), representing the lyrics to two of the tracks; Two images (in JPEG3), representing the cover photograph and other artwork of the album; A text file (in HTML4), re

48、presenting the introductory text for the album. The relationship between these resources and how they relate to the Digital Item itself is expressed in the Digital Item Declaration (DID5). The DID contains, besides the references to the resources, information about the item and/or parts thereof. The

49、se metadata elements are associated through DID mechanisms to the item/resources as shown in Figure 1 overleaf. 1.4 Relationship between Digital Item Declaration and Digital Item Identification Identifiers covered by this specification can be associated with Digital Items, containers, components, and/or fragments thereof by incl
