What is IPTV?
IPTV is defined as multimedia services
such as television, video, audio, text,
graphics and data delivered over IPbased networks which are managed
to support the required level of
QoS/QoE, security, interactivity and
reliability
IPTV is NOT only television
over IP
 it is much more 

What is IPTV Offering?
 NGN
has opened up new possibilities,
enabling user control and
involvement.
IPTV is envisaged to be the major
beneficiary of NGN providing numerous
capabilities for video, audio and data
applications (i.e. triple and quadruple
plays)
New integrated services represent the
real opportunity for service providers
to differentiate their offerings

Focus Group on IPTV
(FG IPTV)
First step in ITU for a
harmonized global solution
for IPTV
Colmbo, Sri Lanka, 7-10 April 2009

FG IPTV Mission Statement
 Coordinate
and promote the
development of global IPTV
standards.
 Take into account the existing work
of the ITU study groups as well as
other Standards Developing
Organizations (SDO), Forums and
Consortia.
Colmbo, Sri Lanka, 7-10 April 2009

Areas of Standardization
 Architecture
and requirements
 QoS/QoE and performance
 Service security and content
protection
 Network and control
 End systems and interoperability
 Middleware and application platforms
ITU-T is committed to producing global
standards for an end-to-end IPTV solution
Colmbo, Sri Lanka, 7-10 April 2009
13
Collaboration With Other SDOs
Liaised with most SDOs involved in
development of IPTV related standards
 Used ATIS IIF, Broadband forum
(formerly DSL Forum) and Home
Gateway Initiative related documents
as input to prepare ITU-T standards
 Good working relationship with DVB
project and ETSI TISPAN

Regional and national bodies and related SDOs
benefit immensely from contributing to ITU-T and
having their work incorporated into globally
14
recognized
and

IPTV Global Standards Initiative

IPTV Global Standards Initiative (I)

After termination of the FG IPTV mandate,
the ongoing work on IPTV was carried out
under the umbrella of a Global Standards
Initiative (the IPTV-GSI)
The focus group output documents were
distributed between relevant study groups.
Coordinated planning of the activities through
co-located meetings of the involved Rapporteur
groups.
IPTV-GSI is now comprised of study groups 9,
11, 12, 13, 16 and 17. These study groups
collaborate with most of ITU-T study groups
Colmbo, Sri Lanka, 7-10 April 2009
18
IPTV Global Standards Initiative (II)

Created the IPTV-JCA (Joint Coordination
Activity)
To oversee IPTV-GSI activities
Extends representation to include other SDOs
involved with ITU-T in the IPTV work
stemming from the results of the IPTV Focus
Group
Convened five meetings in 2008 and
some are planned for 2009
 Has produced the first set of global

Practical Considerations
Colmbo, Sri Lanka, 7-10 April 2009
21
Architecture Approaches

“NGN-based” and “IMS-based” architecture
An IPTV service component is drawn on top of “other
NGN service components” in NGN architecture.
The IPTV service component is achieved by using IMS

“NGN-based” and “non-IMS-based”
architecture
An IPTV service component is drawn on top of “other
NGN service components” in NGN architecture
The IPTV service component is achieved without using
IMS

“Non-NGN-based” architecture
The architecture does not depend on NGN architecture

Implementation Approaches

Operators can choose different approaches
for IPTV deployment:
1.
2.
3.
Build IPTV service using a set of components
from different suppliers, that suppliers
integrate themselves.
Build IPTV service with a pre-integrated set of
components; integrator and component
suppliers.
Build IPTV service with an integrated set of
components for a single supplier.
ITU-T is engaged in the standardisation of
interfaces between IPTV components.

Concluding Remarks (I)






ITU-T responded quickly to market needs for
producing standards on IPTV
ITU is cooperating with other SDOs and industry
forums to produce global standards
First set of Recommendations (i.e. standards) have
been approved and probably are being implemented
ITU-T is a unique place where global IPTV standards
can be created
ITU-T IPTV standardization success comes from
addressing all IPTV related issues and having all IPTV
experts at the same time and in the same place
Work continues at full steam to complete and
complement recently created standards
Providing ITU-T standards compliant products
would benefit all involved.
Colmbo, Sri Lanka, 7-10 April 2009
25
Concluding Remarks (II)
Compliance to global standards would:
 Reduce development costs and product
costs
 Result in capturing bigger market share
 Bring faster introduction to the markets
 Ensure interoperability
 Help all players remain competitive
ITU-T standards compliant products
are key to global interoperability
