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 62481-1-2 has been prepared under technical area 8: Multimedia
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 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.

that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a
colour printer.
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 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 build interoperable networked platforms and devices for the digital
home.

NETWORKED DEVICE INTEROPERABILITY 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 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 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.
