14、tional 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 establishe
15、d 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 fiel
16、d 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
17、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 do

24、n 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 other. The aim for ISO/IEC 21000 is to describe how these various elements fit together. Where gaps exis
25、t, ISO/IEC 21000 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. These specifications will be integrated into the multimedia framework through collaborati
26、on 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 creators and service providers with equal opportunities in the ISO/IEC 21000 enabled ope
27、n 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 ISO/IEC 21000 is to define a multimedia framework to enable transparent and augmented use of multimedia resources across a wide range of n
28、etworks and devices used by different communities. This part of MPEG-21 (ISO/IEC 21000-15) specifies Event Report Requests and Event Reports and how to use these in an ISO/IEC 21000 environment.

30、Reporting 1 Scope 1.1 General This part of ISO/IEC 21000 specifies how to express Event Report Requests (ER-R) that contain information about which Events to report, what information is to be reported and to whom; how to express Event Reports (ER) which are created by an MPEG-21 Peer in response to
31、an Event Report Request when the conditions specified by an ER-R are met. Event Reports Requests are used for specifying a set of conditions upon which a Peer will generate an Event Report and send it to a Recipient. Event Report Requests also specify what information is to be included in the result
32、ing Event Report. The scope of Event Reporting is limited to reporting of Events between Peers, and does not include internal reporting of Events within a Peer. 1.2 Organisation of the Document This part of ISO/IEC 21000 comprises nine clauses. This first clause provides scope and the organisation o
33、f the specification. Clauses 2 to 5.3 contain a set of references, terms and definitions and abbreviations. Clause 6 introduces a high level architecture for Event Reporting, while clauses 7 and 8 specify the syntax and semantics of Event Report Requests, and Event Reports. Clause 9 then specifies t
34、he data types that are frequently used throughout this part of ISO/IEC 21000. Finally, Annex A contains the XML Schema definition for the descriptors defined in clauses 7 and 8 and Annex B and Annex C provide examples of Event Report Requests and Event Reports. 2 Normative References The following r

38、s For the purposes of this document, the following terms and definitions apply. 3.1 Digital Item structured digital object, including a standard representation, identification and meta-data within the MPEG-21 framework NOTE This entity is the fundamental unit of distribution and transaction within t
39、he multimedia framework as a whole.

41、al Item NOTE The term “Terminal” has been deliberately avoided because of its connotation as being the end point in a chain of communication. However, the term Peer explicitly also includes devices or applications that create or alter Digital Items. ISO/IEC TR 21000-1:2004, definition 2.7 3.8 User e
42、ntity that interacts in the MPEG-21 environment or makes use of Digital Items NOTE This includes all members of the value chain (e.g., creator, rights holders, distributors and consumers of Digital Items).
