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 questions 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(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 collaborates 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 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 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
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 corresponding 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
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 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) 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.
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
home 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 significant 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).

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 to
the specific document. At this date, the document will be

A bilingual version of this publication may be issued at a later date.

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 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 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 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 build
interoperable networked platforms and devices for the digital home.

1 Scope
This part of IEC 62481, the DLNA guidelines, specifies DLNA guidelines for DRM
Interoperability Solutions (DIS), which are 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
