14、ticipate 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 conditions determined by agreement
15、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 National Committees. 3) IEC Public
16、ations 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 way in which they are used or fo
17、r 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 IEC Publication and the correspon
18、ding national or regional 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
19、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 to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC
20、 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) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attent
21、ion is drawn to the 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
22、 shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62481-8 has been prepared under technical area 8: Multimedia home systems and applications for end-user network, of IEC technical committee 100: Audio, video and multimedia systems and equipment.

IEC 62481-8:2017 IEC 2017 5 INTRODUCTION 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 enjo
28、y the content, regardless of the source, across different 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 or
29、der 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 innovation, simplicity, and value for consumers. This document serves that purpose and provides vendors with the information needed to buil
30、d interoperable networked platforms and devices for the digital home. 6 IEC 62481-8:2017 IEC 2017 DIGITAL LIVING NETWORK ALLIANCE (DLNA) HOME NETWORKED DEVICE INTEROPERABILITY GUIDELINES Part 8: Diagnostics 1 Scope This part of IEC 62481 specifies guidelines for Diagnostics. The DLNA Diagnostics gui
31、delines focus mostly on the collection of data through test actions and queries. The procedures for troubleshooting and remedies are outside the scope of the DLNA guidelines. The user can be an operator accessing the Diagnostics Application through a TR-069 (an application layer protocol for remote
32、management of end-user devices) management interface, or a technician or end-user accessing it through a browser or screen interface as shown in Figure 1. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requiremen

UPnP BasicManagement Control Point: a UPnP BasicManagement Control Point issues action requests to UPnP BasicManagement Service to implement diagnostics
44、features and functions. 8 IEC 62481-8:2017 IEC 2017 UPnP ConfigurationManagement Control Point: a UPnP ConfigurationManagement Control Point issues action requests to ConfigurationManagement Services to get device information. Diagnostics Application: a Diagnostics Application interfaces with a UPnP
45、 BasicManagement Control Point, UPnP ConfigurationManagement Service, 1905 Management Primitives, and other not-specified-by-DLNA diagnostics Device Functions to provide meaningful and actionable information regarding DLNA devices. It provides input to a user or management system interface to enable
46、 a user to control and see results from diagnostics features and functions. 1905 Management Primitives: a function that provides a 1905 signaling capability on a physical interface. It can also receive requests and report 1905 data to a co-resident Diagnostics Application. 5.3 Device Capabilities Fo
47、r the Diagnostics guidelines, the following Device Capabilities are defined: a Diagnostics Endpoint (+DIAGE+) with the role of offering diagnostics services and responding to diagnostics action requests; a Diagnostics Controller (+DIAGC+) with the role of providing a Diagnostics Application and a co
48、ntrol point for issuing action requests to a Diagnostics Endpoint. 5.4 System usages The diagnostics system usage has a Diagnostics Controller capability to instruct a Diagnostics Endpoint capability to execute specific diagnostics actions. +DIAGE+ +DIAGC+ UPnP BM Control Point Diagnostics Applicati
