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 text of this standard is based on the following documents:

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.

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 Systems layer
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 carriage, as defined in ETSI TS 102 034 shall be
applied, i.e. the program association table (PAT) and program map table (PMT) are
required, and ETSI EN 300 468 is optional. However, the carriage of EIT for the
associated content is recommended, as specified in 5.2.4 of IEC 62766-3:2016.
• The transport stream may contain EIT as specified in 5.2.4 of IEC 62766-3:2016.
• The transport stream may contain MPEG-2 encoded AIT as defined in 5.3 of
ETSI TS 102 809:2013. This shall be supported as defined in IEC 62766-5-1 and below:

− 16 − IEC 62766-2-1:2016  IEC 2016
– The application type used for DAE applications in 5.2.2 of ETSI TS 102 809:2013 shall
be 0x0011 (to signal “OIPF DAE”).
– If the optional data_broadcast_id_descriptor is used for carousels carrying DAE
applications then the value to be used for the data_broadcast_id field shall be 0x0150
(to signal “OIPF Object Carousel”).
– A maximum of one sub-table (i.e. using only one PID) signalling DAE applications shall
be transmitted per service.
– All clauses of the AIT sub-table for DAE applications shall be transmitted at least once
every second.
• The transport stream may contain DAE applications transmitted using the DSM-CC object
carrousel as defined in 7.1 of ETSI TS 102 809:2013.
• The transport stream may contain “do-it-now” DSM-CC stream events as defined by 8.1 of
ETSI TS 102 809:2013.
• The maximum streaming bitrate for a transport stream carrying SD content shall not
exceed 8.0 Mbit/s.
• The maximum streaming bitrate for a transport stream carrying HD content shall not
exceed 24,0 Mbit/s.
• Transport streams may contain media zone information (zone map), possibly including
navigation constraints, using the signalling mechanisms specified in the Marlin Dynamic
Media Zones specification. Rules about the handling of Marlin media zone information by
the OITF, for both unprotected and protected content, are contained in Clause 6 of
IEC 62766-7:— . This means that an MPEG-2 transport stream may contain a DMZ
descriptor in the PMT and one or more private_clauses in the stream, with PID as
signalled in the DMZ descriptor, and containing zone map information (i.e., navigation
constraints), all according to Marlin Dynamic Media Zones, Sublause 7.2.
• Transport streams containing 3D content shall comply with the following requirements:
– the PMT shall include the AVC_video_descriptor according to ETSI TS 101 547:2012,
Subclause 6.1.
– if SDT and/or EIT are present, they shall meet the requirements of
ETSI TS 101 547:2012, Subclause 6.2.
The preceding specification of the MPEG-2 transport stream format is referred to as the TS
systems layer format.
An additional variant of the TS format is defined, namely the time-stamped MPEG-2 transport
stream, as defined in IEC 62481-2:2013, 9.3.4, applied to the TS systems layer format.
The time-stamped MPEG-2 transport stream format is referred to as the TTS systems layer
format.
The methods to protect (encrypt) MPEG-2 transport streams are specified in IEC 63766-7.
IEC 63766-7 specifies two approaches for content and service protection, namely the
terminal-centric approach and the gateway-centric approach.
For the terminal-centric approach and for the output of the CSP gateway in the gateway-
centric approach, the protected MPEG-2 transport stream shall comply with protection system
signalling as specified in ISO/IEC 13818-1 and may use the conditional access table (CAT) as
defined therein. This protected format is referred to generically as PF.
___________
Under preparation. Stage at the time of publication: IEC/CDV 62766-7:2015.

For the gateway-centric approach, the input stream to the CSP gateway is not specified,
except in the case of the CI Plus gateway-centric approach, where the input stream shall
comply with the PF format. PF applies to both the TS and TTS systems layer formats.
The protected MPEG-2 transport stream format for the terminal-centric approach is further
defined in the Marlin Broadband Transport Stream Specification and is referred to as BBTS.
BBTS applies to both the TS and TTS systems layer formats.
The OITF shall support the application signaling and in-band delivery of DAE applications via
the IP channel, as defined above. In environments where the broadcast channel is based on
DVB network technologies and uses DVB-SI as specified in ETSI EN 300 468, the OITF shall
also support the application signalling and in-band delivery of DAE applications via the
broadcast channel.
5.3 MP4 file format
The carriage of audio/video content and related information (e.g. subtitles) in file-based
formats (systems layer format: MP4) shall use the MP4 File Format ISO/IEC 14496-14 and
ISO Base Media File Format ISO/IEC 14496-12 with the constraints defined in 9.4.4.3 of
IEC 62481-2:2013, except for 9.4.4.3.3 and 9.4.4.3.10. This is the preferred format for MP4-
based unprotected content.
For services that allow the real-time playback of downloaded content before the download has
been completed (e.g. progressive download), the following additional constraints apply:
• the moof box shall be used according to 9.4.4.3.8 of IEC 62481-2:2013;
• the size of the moov box shall be equal to or less than 2 MB;
• use of the pdin box, defined in 8.43 of ISO/IEC 14496-12:2012, is recommended.
A service may apply the additional constraint on moov box size according to 9.4.4.3.11 of
IEC 62481-2:2013, in order to provide content compliant to the DLNA specification.
In addition, carriage of ITU-T Recommendation H.264/AVC content in the MP4 systems layer
shall be conformant to the AVC file format standard ISO/IEC 14496-15.
In addition, carriage of MPEG-4 AAC/HE-AAC content in the MP4 systems layer shall be
conformant to the MP4 file format standard ISO/IEC 14496-14.
The storage of AC-3 and Enhanced AC-3 content in the MP4 file format shall be conformant to
Annex F of ETSI TS 102 366:2008.
MP4 files may contain media zone information (zone map), possibly including navigation
constraints, using the signalling mechanisms specified in the Marlin Dynamic Media Zones
specification. Rules about the handling of Marlin media zone information by the OITF, for both
unprotected and protected content, are contained in Clause 6 of IEC 62766-7:—. This means
that an MP4 file may contain one or more mDMZ boxes containing zone parameters and zone
properties (i.e., navigation constraints) according to the Marlin Dynamic Media Zones
specification Subclause 7.1.
The methods to protect (encrypt) MP4-based file formats are specified in IEC 62766-7:—.
Four protection methods are specified and they are allocated the protection format labels as
follows:
• OMA PDCF, specified in the OMArlin Specification, is referred to as PDCF,
• OMA DCF, specified in the OMArlin Specification, is referred to as DCF,
• Marlin IP MP
