21、mprising 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 to other activities, IEC publishes International St
22、andards, 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 in the subject dealt with may participate in this pr
23、eparatory 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 conditions determined by agreement between the two org
24、anizations. 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 National Committees. 3) IEC Publications have the for
25、m 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 way in which they are used or for any misinterpreta
26、tion 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 IEC Publication and the corresponding national or re
27、gional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of 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 ou
28、t by independent certification bodies. 6) All users should 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 Committee
29、s for any personal injury, property damage or other damage 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
30、 Normative references cited in this publication. Use of the referenced publications is indispensable for the 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
31、responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. However, a technical committee may propose the publication of a technical report when it has collected data of a different kind from that which is normally publ
32、ished as an International Standard, for example “state of the art”. IEC 62636, which is a technical report, 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 technical report is b
33、ased on the following documents: Enquiry draft Report on voting 100/1561/DTR 100/1611/RVC Full information on the voting for the approval of this technical report can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Direc
34、tives, Part 2. TR 62636 IEC:2009(E) 5 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 wil
35、l be 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
36、 understanding of its contents. Users should therefore print this publication using a colour printer. 6 TR 62636 IEC:2009(E) INTRODUCTION IEC 62227, which defines the digital rights permission code, is structured so that information required by engineers familiar with how permission information is c
37、oded can easily access it. However, for engineers who are not familiar with the code, there are few descriptions of specific service scenarios and the permission code that corresponds to them. For these engineers it is therefore difficult to understand how to implement a digital rights permission co
38、de using just the information given in IEC 62227. This Technical Report provides guidelines for digital rights permission code technology to supplement the information presented in IEC 62227 and to foster the use of digital rights permission code.

39、S IMPLEMENTATION OF DIGITAL RIGHTS PERMISSION CODE 1 Scope This Technical Report provides guidelines to implement the digital rights permission code. It gives examples of fixed length permission codes derived from restricted code length profiling by using 23 specific usage scenarios to profile the v
40、ariable-length digital rights permission code defined in IEC 62227 as fixed length digital rights permission code. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated refer
41、ences, the latest edition of the referenced document (including any amendments) applies.

42、 content to a certain receiving entity under a certain set of permission classifications and usage conditions NOTE The issuing entity and/or the receiving entity may not only be human, but also a device, storage medium, organization, domain or another entity. 3.1.2 home server client device that ser
43、ves as a gateway to a home domain 3.1.3 compliant device device that possesses functions to control content access as specified in a compliant license 3.1.4 domain set of actors to which a common set of rules apply in the context of content management 3.1.5 subscription fee-based permission that cha

49、ecture For Intelligent Attachment WMT Windows Media Technology 4 Purpose and justification for this TR 4.1 General The digital rights permission code defined in IEC 62227 is variable-length, and there is no upper limit to the code length. This is because it was designed to be a very versatile specification capable of encoding permission conditions for a great variety of anticipated usage scenarios.
