Part 4-2: Examples of IPTV protocol sequences

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.

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.

4.2.2 Content reporting and content reporting management
4.2.2.1 Content reporting
Figure 3 shows a call flow for an OITF initiating content reporting. Below is a brief description
of the call flow.
Step 1: It is assumed that the OITF established a regular scheduled content session, and
that the IPTV Control FE indicated its willingness to receive content Reporting Info
Package (through Recv-Info header in SIP 200 OK response to the INVITE). It is
assumed that the timer for content reporting is pre-configured.
Step 2: If zapping is performed and stopped for the configured timer or in case of powerup
without zapping and the user settled on a channel for the configured timer, the
OITF issues a request to the IG for content reporting.
Step 3: The IG validates the request then issues a SIP INFO to the network including the
content Reporting Info Package to report the watched content.
Step 4: The ASM forwards the request to the IPTV control FE.
Steps 5-7: The IPTV control FE generates a 200 OK that is proxied all the way to the IG, then
from the IG to the OITF it is forwarded in an HTTP 200 OK response.
Step 8: The user performs channel zapping.
Step 9: The user stops zapping and finally settles on a channel for the configured timer.
Step 10: This step reports the watched content and is similar to steps 2-7.

4.2.2.2 Management of content reporting
Figure 4 shows a call flow for the management of content reporting. Below is a brief
description of the call flow.
Step 1: The OITF established a scheduled content and performs content reporting as
required by the IPTV Control FE.
Step 2: The OITF performs content reporting when user performs zapping then stops
for the configured time.
Step 3: The OITF issues an HTTP HNI-IG PENDING_IG request to the IG. This request
can be issued at any time after step 1.
Step 4: At some point in time, the IPTV control FE decided that it does not want any
more content reporting. The IPTV control FE sends a SIP UPDATE with the
Recv-Info header set to ‘nil’ to the ASM to that effect.
Step 5: The ASM forwards the SIP UPDATE to the IG.
Step 6: The IG forwards the SIP UPDATE in an HTTP 200 OK response to the OITF.
Steps 7-9: The OITF issues an HTTP POST request to the IG that includes the SIP 200
OK response. The SIP 200 OK is forwarded all the way to the IPTV control FE.
Step 10: The user performs channel zapping and no content reporting is performed.
Step 11: The OITF issues an HTTP HNI-IGI PENDING_IG request to the IG.
Steps 12-14: These steps request the OITF to start reporting the watched content and are
similar to steps 4-6. The difference is that the Recv-Info header is set to
content Reporting Info Package.
Steps 15-17: The OITF issues an HTTP POST request to the IG that includes the SIP 200
OK response. The SIP 200 OK is forwarded all the way to the IPTV Control FE.
Step 18: This step reports the watched content. See Figure 4 for the detailed call flow.
