16、tocols Extended Digital Media Renderer 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 ques
17、tions 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
18、(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 col
19、laborates 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
20、 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 all reasonable efforts are made to ensu
21、re 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
22、 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 of conformity. Independent certificatio
23、n 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 atta
24、ch 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
25、) 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 publicatio
26、n. 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 62481-1-2 has been prepared under technical area 8: Multimedi
27、a home systems and applications for end-user network IEC technical committee 100: Audio, video and multimedia systems and equipment. The text of this International Standard is based on the following documents: CDV Report on voting 100/2736/CDV 100/2885/RVC Full information on the voting for the appr
28、oval 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. 4 IEC 62481-1-2:2017 IEC 2017 A list of all parts of IEC 62481 series, published under the general title Digital Li
29、ving 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 IEC website under “http:/webstore.iec.ch“ in the data related
30、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. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains col

IEC 62481-1-2:2017 IEC 2017 5 INTRODUCTION Consumers are acquiring, viewing, and managing an increasing amount of digital media (photos, music, and
32、 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 devices and locations in the home. The digital home vision integrates the Internet, mobile, and broadcast
33、networks through a seamless, interoperable network, which will provide a unique opportunity for manufacturers and consumers alike. In order to deliver on this vision, a common set of industry design guidelines is needed that allows vendors to participate in a growing marketplace, leading to more inn
34、ovation, 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 digital home. 6 IEC 62481-1-2:2017 IEC 2017 DIGITAL LIVING NETWORK ALLIANCE (DLNA) HOME NETWORKED DEVICE INT
35、EROPERABILITY GUIDELINES Part 1-2: Architecture and protocols Extended Digital Media Renderer 1 Scope The DLNA Guidelines Parts 1 to 3 introduce a number of device classes to identify specific roles that connected endpoints implement in the network. Devices can act as content sources (e.g., Digital
36、Media Servers, Push Controllers), and as content sinks (Digital Media Renderers or Digital Media Players). Having two types of content sinks has been a useful strategy to accelerate the initial deployment phase. However, many of the modern receiver devices now include both types. Consequently, there
37、 is a need to define a receiver device that combines both types. This document addresses this issue and, specifically, it describes a device class for an Extended Digital Media Renderer (XDMR) and implementation guidelines for combining a Digital Media Renderer and a UPnP Media Server Control Point.
