15、SSION _ MULTIMEDIA HOME SERVER SYSTEMS CONCEPTUAL MODEL FOR DOMAIN MANAGEMENT FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
16、 international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (he
17、reafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also pa
18、rticipate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible,
19、 an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While a
20、ll reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to a
21、pply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation o
22、f conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this p
23、ublication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indire
24、ct, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the
25、correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to pr
26、epare International Standards. In exceptional circumstances, a technical committee may propose the publication of a technical specification when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts, or the subject is still under technical
27、 development or where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard. Technical specifications are subject to review within three years of publication to decide whether they can be transformed into International Standards. IEC 625
28、79, which is a technical specification, has been prepared by technical area 8: Multimedia home server systems of IEC technical committee 100: Audio, video and multimedia systems and equipment. DD IEC/TS 62579:2010TS 62579 IEC:2010(E) 5 The text of this technical report is based on the following docu
29、ments: Enquiry draft Report on voting 100/1626/CDV 100/1676/RVC Full information on the voting for the approval of this technical specification can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The
30、committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be be transformed into an International standard,
31、 reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct under
32、standing of its contents. Users should therefore print this document using a colour printer. DD IEC/TS 62579:2010 6 TS 62579 IEC:2010(E) INTRODUCTION Compared with analog media, digital contents can be copied easily and the copies dont decline in quality. So it is certain that digital contents shoul
33、d be protected. But, compared to the rights of private records on analog media, it is hard for users to enjoy their digital contents freely. The concept of a domain has been defined in several organizations for the purpose of improving user convenience. Domains enable users to consume and manage the
34、ir digital contents in a manner which is more like enjoying analog contents. Users can enjoy digital contents, which are stored on a device, not only on the device where they are stored on but also on other devices within the same domain such as home or school, etc. From a standpoint of copyrights,
35、it means that the contents are allowed to be consumed with a copy control technology on limited devices. A domain manages both user convenience and contents protection. Depending on the scenario of the operated domain, the limit and the boundary on domain configuration can be flexible. DD IEC/TS 625
36、79:2010TS 62579 IEC:2010(E) 7 MULTIMEDIA HOME SERVER SYSTEMS CONCEPTUAL MODEL FOR DOMAIN MANAGEMENT 1 Scope This Technical Specification defines the conceptual model of domain management, which includes terms, requirements and reference models. The domain is a set of devices, users, and/or other ent
37、ities which can share contents. Entities within a domain are allowed to play, copy and move content and usage rules to other entities within the same domain. Some existing systems have been proposed in this field of domain, but various vocabularies and models are specified. This situation causes con
38、fusion and misunderstanding of systems, and disturbs interoperability. This Technical Specification is intended to standardize the vocabularies and clarify the models. All kinds of digital content, including broadcast content which needs to be protected, are considered in this specification. On the
39、other hand, rights management and content protection technology are beyond the scope of this specification. NOTE In addition, network protocol and media format for content sharing and exchange are also out of the scope of this specification. Refer also to IEC 62481-1 and IEC 62481-2 for interoperabi
40、lity guidelines 2 Terms, definitions and abbreviations 2.1 Terms and definitions For the purposes of this document the following terms and definitions apply. NOTE These are necessary terms used in the field of domain management. 2.1.1 content issuer rights issuer or contents holder 2.1.2 content dig
41、ital data, such as movies, images, audio and software, etc. 2.1.3 content key encryption key related to each content 2.1.4 domain set of devices, users, or other entities which can share contents and associated usage rules 2.1.5 domain ID unique identifier which is related with a domain 2.1.6 domain

48、ibes how domain management is specified and how the scenario of domain is assumed in existing specifications on DRM. This leads to what a domain management standard should contain. In general, users can consume content without restriction of the location on all home electric appliances, cell phones,
49、 mobile devices or car devices in the domain. The devices can share content according to a permission system, which includes the use situation and the quality, in each domain. 3.2 Example 1: A domain in ARIB TR-B27 A device is allowed to copy content and a certain part of the usage rule to storage media. The content is played according to the restriction of the usage rule, as shown in Figure 1. Figure 1 Domain in ARIB T
