The interface to the access network is generally common, but there are significant variations on how the other components are structured and behave. In a setting where even subtle variations on protocols or data formats can be a barrier to interoperability. 9

IPTV Standards Development Organizations Digital Video Broadcasting(DVB) European Telecommunications Standards Institute Telecommunications and Internet converged Services and Protocols for Advanced Networking(ETSI TISPAN) International Telecommunications Union— Telecommunication Standardization Sector (ITU-T) Open IPTV Forum (OIPF) 10

DVB DVB released DVB-IPTV 1.4 handbook in The goal of the handbook is to specify technologies on the interface between an IP network and a Home Network End Device (HNED). 11

ETSI TISPAN ETSI TISPAN was chartered in 2004 to standardize Fixed NGN, working alongside 3GPP which concentrated on mobile NGN. TISPAN has published NGN R2 in June There are two variants of IPTV in TISPAN R2 (and also in R3): Dedicated IPTV and IMS-Based IPTV. 15

ITU-T IPTV Focus Group and GSI ITU-T responsible for fostering cooperative standards for telecommunications equipment and systems. 18

ITU-T IPTV Focus Group and GSI 19

ITU-T IPTV Focus Group and GSI Definition of IPTV: “IPTV is defined as multimedia 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.” 20

ITU-T IPTV Focus Group and GSI IPTV Domains: Four IPTV domains are identified including content provider, service provider, network provider and end user. 21

ITU-T IPTV Focus Group and GSI IPTV Architectural Approaches: Three IPTV architecture approaches are identified that enable service providers to deliver IPTV services:  Non-NGN IPTV functional architecture (Non- NGN IPTV),  NGN-based non-IMS IPTV functional architecture (NGN-Non-IMS IPTV),  NGN IMS-based IPTV functional architecture (NGN-IMS-IPTV). 22

ITU-T IPTV Focus Group and GSI IPTV Functional Architecture: Functions and functional blocks described in this clause are common to all architectural approaches. 23

ITU-T IPTV Focus Group and GSI 24

OIPF The objective to specify a common and open end-to-end solution for supplying a variety of IPTV and internet multimedia services. 25

OIPF 26

Conclusion The pursuit of a single IPTV standard may have failed. With so many available standards, vendors and operators will need to make hard choices. 27
