31、 is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition
32、to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested i
33、n the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with cond
34、itions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC Nat
35、ional Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical Content of IEC Publications is accurate, IEC cannot be held responsible for the w
36、ay 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 apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IE
37、C Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should
38、ensure that they have the latest edition of this publication. 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
39、of any nature whatsoever, whether direct or indirect, 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
40、 referenced publications is indispensable for the correct application of this publication. International Electrotechnical Commission (IEC) draws attention to the fact that it is claimed that compliance with this document may involve the use of patent. IEC takes no position concerning the evidence, v
41、alidity and scope of these patent rights. The holder of this patent right has assured IEC that it is willing to negotiate licences under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the holders of these patent rights a
42、re registered with IEC. Information may be obtained from: DENTSU INC. Media Marketing Division 1-8-1, Higashi-shimbashi, Minato-ku, Tokyo 105-7001 JAPAN Attention is drawn to the possibility that some of the elements of this standard may be the subject of patent rights other than those identified ab
43、ove. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62227 has been prepared by technical area 8: Multimedia home server systems, of IEC technical committee 100: Audio, video and multimedia systems and equipment. The text of this standard i
44、s based on the following documents: CDV Report on voting 100/1287/CDV 100/1374/RVC 62227 IEC:2008(E) 7 Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC
45、Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until the maintenance result 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 reconfirmed;
46、withdrawn; replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. 8 62227 IEC:2008(E) INTRODUCTION The common ID system is used to systematically identify every entity, device and content that would be involved in the course of digitally dis
47、tributing content. The permission code can express various sets of permission information and permission conditions necessary for content transmission in a remarkably short code form. The permission code is not defined from a technical perspective, but rather on the basis of permission information t
48、hat rights holders actually employ in the field, even if the permission code is recognized for its technical effectiveness with respect to digital distribution of content. 62227 IEC:2008(E) 9 MULTIMEDIA HOME SERVER SYSTEMS DIGITAL RIGHTS PERMISSION CODE 1 Scope This International Standard defines th
49、e permission code, a set of permission related information in short code form, primarily intended for home server systems. The permission code is comprised of a common ID system (content ID, issuer ID, receiver ID, device ID, etc.) and a narrowly-defined permission code. The common ID system is used to systematically identify every entity, device and con
