Conclusion


ITU Definition of IPTVMultimedia services, such as Television; Video; Audio; Text; Graphics; Data,

delivered over IP based networks managed to provide the required level of

QoS/QoE, security, interactivity and reliability.

o IPTV is NOT EXCLUSIVELYo Video streaming o Over the Interneto For PC


Why standardize IPTV?

Lower costWider MarketBetter Quality of Service and ExperienceMore consorted securityOpen infrastructureInnovation and new services

Standardized HTML gave us Web; Standardized IPTV will give a new Internet


5

Pros and Cons of Proprietary STB Solution

Pros:More Versatility and AdaptabilityMore Resources and Control on TerminalEasier differentiation

ConsMore expensive for the Service providerMore limited in number (Potential market should be large enough to get volume discount)More control means more responsibility


Standard IPTV as Market DriverStandardized IPTV will be as ubiquitous as present-day telephones and FAX machinesStandardized IPTV will allow a wide range of selection and variety of terminals in retail marketStandardized IPTV will allow low-priced terminalsConsumers can choose as they want; Service Differentiation is promotedStandardized IPTV will create a big market not only for conventional content business but also for various related services: e.g. e-health and e-learning

6

It will be the infrastructure that gives a secure, accessible window for Next Gen ICT world


ITU’s Work on IPTVIPTV considered one of the most important service applications on NGNIt is the most salient show case of NGNITU-T has been spearheading the standardization in IPTV for NGNFocus Group on IPTV (2006-2007)

Responding to market demands standardFirst set of draft on Architecture, QoS, Security, End-Systems and Multimedia Application

IPTV Global Standardization Initiative (GSI) (2008-)Coordinating all ITU-T’s IPTV related activitiesCurrently 15 Recommendations approved by 6 Study Groups,Every two to three months

Characteristics of ITU-T IPTV

End-to-End Solution Collaboration with CE and other VendorsStrong representation from Telcos and other ServicersLearning from Broadcasters and other Content Servicers –contributions from DVBStrong Liaisons with other SDOs –architecture and requirements harmonized with ATIS and ETSIOpen and Interoperable

ITU-T Liaisons on IPTV

11

o With ATIS-IIF, DVB, ETSI on Service Discovery, Metadata, and other solutions

o With W3C on HTML,CSS,DOM,SVG for IPTV o With IETF on Error Recovery and Signalingo With 3GPP on Mobile related matterso With IEC on Terminals, “Rights Information

Interoperability” and “Power Consumption”o With MPEG on “Advanced IPTV Terminal”

Working closely through Liaisons and joint meetings,

To ensure interoperability and quality of standards

H.700 Series: Multimedia for IPTV

A new series of Recommendations for IPTV Multimedia Services and applications for IPTVConsists of the following subseries:

H.700-H.719 (General aspects)H.720-H.729 (IPTV Terminal Devices)H.730-H.739 (IPTV Middleware)H.740-H.749 (IPTV Application Event Handling)H.750-H.759 (IPTV Metadata)[H.750] H.IPTV-MD Metadata for IPTVH.760-H.769 (IPTV Multimedia Application Framework)H.770 –H.779 (IPTV Service Discovery)

Mar del Plata, Argentina, 2 September 2009 13


H.701: Error RecoveryA method to guarantee the quality of serviceForward Error Correction (FEC) and Retransmission, two well-known methods, are covered.

Retransmission is a way in which to request lost packets to be retransmitted when a packet-loss is detected at the receiving end.FEC is a way to send redundant data with the content so that the receiving side can retrieve information even when there is a packet loss.

Harmonized with ETSI and IETF (COP3 and Raptor)Defining Syntax and Configuration Protocols for FEC


H.770: IPTV Service DiscoveryGeneral Framework for discovering and selecting service providers and servicesAllows user to enjoy various services and service providers easilyMust-have for open, managed platform
