17、art 4: DRM interoperability solutions 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 international co-operation on all quest
18、ions 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 (hereafter referred to as “IEC Publication(
19、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 participate in this preparation. IEC colla
20、borates 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, an international consensus of opinion o
21、n 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 all reasonable efforts are made to ensure
22、 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 apply IEC Publications transparently to t
23、he 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 of conformity. Independent certification
24、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 publication. 7) No liability shall attach
25、 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 indirect, or for costs (including legal fees)
26、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 correct application of this publication.
27、 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. International Standard IEC 62481-4 has been prepared under technical area 8: Multimedia ho
28、me systems and applications for end-user network, of IEC technical committee 100: Audio, video and multimedia systems and equipment. This second edition cancels and replaces the first edition published in 2014. This edition constitutes a technical revision. This edition includes the following signif
29、icant technical changes with respect to the previous edition: a) removal of references to Mobile Digital Media Uploader (M-DMU); b) removal of references to Mobile Digital Media Downloader (M-DMD). 4 IEC 62481-4:2017 IEC 2017 The text of this International Standard is based on the following document
30、s: CDV Report on voting 100/2733/CDV 100/2883/RVC Full information on the voting for the approval of this International Standard can be found in the report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of
31、 IEC 62481 series, published under the general title Digital living network alliance (DLNA) home networked device interoperability guidelines, can be found on the IEC website. The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the
32、 IEC website under “http:/webstore.iec.ch“ in the data related to the specific document. At this date, the document will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. IEC 62481-4:2017 IEC 2017 5 INTRODUCTI
33、ON Consumers are acquiring, viewing, and managing an increasing amount of digital media (photos, music, and video) on devices in the consumer electronics (CE), mobile, and personal computer (PC) domains. As such, they want to conveniently enjoy the content, regardless of the source, across different
34、 devices and locations in the home. The digital home vision integrates the Internet, mobile, and broadcast networks through a seamless, interoperable network, which will provide a unique opportunity for manufacturers and consumers alike. In order to cater for this need, a common set of industry desi
35、gn guidelines is needed that allows vendors to participate in a growing marketplace, leading to more innovation, simplicity, and value for consumers. This document serves that purpose and provides vendors with the information needed to build interoperable networked platforms and devices for the digi
36、tal home. 6 IEC 62481-4:2017 IEC 2017 DIGITAL LIVING NETWORK ALLIANCE (DLNA) HOME NETWORKED DEVICE INTEROPERABILITY GUIDELINES Part 4: DRM interoperability solutions (DIS) 1 Scope This part of IEC 62481, the DLNA guidelines, specifies DLNA guidelines for DRM Interoperability Solutions (DIS), which a
37、re defined as methods to enable the secure transfer and use of protected commercial content between different implementations on network media devices. This content could be protected by different content protection technologies. In this document, they are referred to as DRMs. The guidelines are not
38、 intended to replace or disable other interoperability mechanisms that could already be in place, for example DLNA Link Protection guidelines stated in IEC 62481-3:2017 or mechanisms provided by underlying DRMs. 2 Normative references The following documents are referred to in the text in such a way
39、 that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 62481-1-1:2017, Digital living network alliance (DLNA) hom
