Part 2-2: HTTP adaptive streaming

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

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.

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

Part 2-2: HTTP adaptive streaming



1 Scope
This part of IEC 62766 specifies media formats for adaptive unicast content streaming over
HTTP.
Two HTTP adaptive streaming formats are specified. The first is based entirely on MPEG
DASH. The second is the OIPF “HTTP adaptive streaming” (HAS) format, which is based upon
3GPP’s release 9 adaptive HTTP streaming (AHS) format, with some profiling and extensions
to add the features of media components and support for MPEG-2 transport stream content
segment format. The latter format was specified before MPEG DASH had been published. It is
retained due to usage in some legacy applications.
2 Normative references

4 Adaptive streaming in the OIPF IPTV solution
Rather than providing a content asset as a single file or stream, in the case of HTTP adaptive
streaming, a service provides a content item in multiple bitrates in a way that enables a
terminal to adapt to (for example) variations in the available bandwidth by seamlessly
switching from one version to another, at a higher or lower bitrate, while receiving and playing
the content. This is achieved by encoding a content item in alternative representations of
different bitrates and segmenting these representations into temporally aligned and
independently encoded segments. This results in a matrix of segments, as depicted
generically in Figure 1.
A content item may consist of several components.
Service discovery procedures refer to a content resource. A content resource consists of one
or more time-sequential periods.
