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 62766-2-1 has been prepared by IEC technical committee 100:
Audio, video and multimedia systems and equipment.

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

INTRODUCTION
The IEC 62766 series is based on a series of specifications that was originally developed by
the OPEN IPTV FORUM (OIPF). They specify the user-to-network interface (UNI) for
consumer terminals to access IPTV and open internet multimedia services over managed or
non-managed networks as defined by OIPF.
The set of media formats specified in this standard comprises:
• audio-video media formats (Clause 4), being combinations of the individual formats below.
• systems layer formats (Clause 5),
• video codecs and their usage (Clause 6),
• subtitle formats and their usage (Clause 7),
• teletext formats and their usage (Clause 8),
• audio codecs and their usage (Clause 9), and
• graphics and still image codecs and formats (Clause 10).
For each of these codecs and formats, it is specified how they apply to the overall system and
to the various IPTV services (described in IEC 62766-1), including the implications for
interoperability.
Figure 1 summarises the set of media formats specified by the present document in the form
of a media formats stack. Media formats are specified at the content layer (audio, video, etc.)
and for the systems layer. Transport protocols below the systems layer are specified in
IEC 62766-4-1.

CONSUMER TERMINAL FUNCTION FOR ACCESS TO IPTV
AND OPEN INTERNET MULTIMEDIA SERVICES –

Part 2-1: Media formats
1 Scope
This part of IEC 62766 specifies formats for the audio/video content provided by IPTV
services using fixed line access networks or mobile access networks and voice and video
telephony services. It does not apply to the broadcast channel input of hybrid devices except
where explicitly specified.
This part of IEC 62766 defines formats for the delivery of 3D video. At the present time,
delivery to fixed terminals is targeted. No special provision is made for mobile or portable
devices.
This standard defines the media formats utilised on the UNI reference point UNIT-17 of the
Open IPTV Forum functional architecture.

5.1 General
At the systems layer, two formats for the carriage of audio/video content are defined, namely
MPEG-2 transport stream and MP4 file format.
Audio/video content protection is performed at the systems layer, as defined in IEC 62766-7.
This standard describes the protected formats in relation to the total set of media format
definitions.
5.2 MPEG-2 transport stream
The carriage of audio/video content and related information (e.g. subtitles) in an MPEG-2
transport stream shall be in compliance with ETSI TS 101 154:2012, Clause 4, with the
following additional constraints:
• Only a single program shall be contained in the transport stream. The transport stream
shall contain only one program map table (PMT).
• The “TS Optional-SI” profile of PSI/SI carria
