FOREWORD
1) ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission) form the
specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in
the development of International Standards. Their preparation is entrusted to technical committees; any ISO and
IEC member body interested in the subject dealt with may participate in this preparatory work. International
governmental and non-governmental organizations liaising with ISO and IEC also participate in this preparation.
2) In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.
3) The formal decisions or agreements of IEC and ISO 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 and ISO member bodies.
4) IEC, ISO and ISO/IEC publications have the form of recommendations for international use and are accepted
by IEC and ISO member bodies in that sense. While all reasonable efforts are made to ensure that the
technical content of IEC, ISO and ISO/IEC publications is accurate, IEC or ISO cannot be held responsible for
the way in which they are used or for any misinterpretation by any end user.
5) In order to promote international uniformity, IEC and ISO member bodies undertake to apply IEC, ISO and
ISO/IEC publications transparently to the maximum extent possible in their national and regional publications.
Any divergence between any ISO/IEC publication and the corresponding national or regional publication
should be clearly indicated in the latter.
6) ISO and IEC provide no marking procedure to indicate their approval and cannot be rendered responsible for
any equipment declared to be in conformity with an ISO/IEC publication.
7) All users should ensure that they have the latest edition of this publication.
8) No liability shall attach to IEC or ISO or its directors, employees, servants or agents including individual experts
and members of their technical committees and IEC or ISO member bodies 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 of, use of, or reliance upon, this ISO/IEC publication or any other IEC,
ISO or ISO/IEC publications.
9) 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.
10) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
International Standard ISO/IEC 29341-3-1 was prepared by UPnP Forum Steering
committee , was adopted, under the fast track procedure, by subcommittee 25:
Interconnection of information technology equipment, of ISO/IEC joint technical committee 1:
Information technology.
This International Standard replaces ISO/IEC 29341-3-1, first edition, published in 2008, and
constitutes a technical revision.
The list of all currently available parts of the ISO/IEC 29341 series, under the general title
Information technology – UPnP device architecture, can be found on the IEC web site.
This International Standard has been approved by vote of the member bodies, and the voting
results may be obtained from the address given on the second title page.

1 Overview and Scope
1.1 Introduction
This document describes the overall UPnP AV Architecture, which forms the foundation for
the UPnP AV Device and Service templates. The AV Architecture defines the general
interaction between UPnP Control Points and UPnP AV devices. It is independent of any
particular device type, content format, and transfer protocol. It supports a variety of devices
such as TVs, VCRs, CD/DVD players/jukeboxes, settop boxes, stereos systems, MP3
players, still-image cameras, camcorders, electronic picture frames (EPFs), and the PC. The
AV Architecture allows devices to support different types of formats for the entertainment
content (such as MPEG2, MPEG4, JPEG, MP3, Windows Media Architecture (WMA), bitmaps
(BMP), NTSC, PAL, ATSC, etc.) and multiple types of transfer protocols (such as IEC-
61883/IEEE-1394, HTTP GET, RTP, HTTP PUT/POST, TCP/IP, etc.). The following clauses
describe the AV Architecture and how the various UPnP AV devices and services work
together to enable various end-user scenarios.
1.2 Goals
The UPnP AV Architecture was explicitly defined to meet the following goals:
• To support arbitrary transfer protocols and content formats.
• To enable the AV content to flow directly between devices without any intervention from
the Control Point.
• To enable Control Points to remain independent of any particular transfer protocol and
content format. This allows Control Points to transparently support new protocols and
formats.
• Scalability, i.e. support of devices with very low resources, especially memory and
processing power as well as full-featured devices.
