IPTV Introduction • IPTV Standards Development Organizations • DVB • ETSI TISPAN • ITU-T • OIPF • Conclusion • References Outline
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 quality of service and experience, security, interactivity and reliability. IPTV Introduction
IPTV features • Support for interactive TV • Time shifting • Personalization • Low bandwidth requirements • Accessible on multiple devices IPTV Introduction
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. IPTV Introduction
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) IPTV Standards Development Organizations
DVB released DVB-IPTV 1.4 handbook in 2008. • The goal of the handbook is to specify technologies on the interface between an IP network and a Home Network End Device (HNED). DVB
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 2008. There are two variants of IPTV in TISPAN R2 (and also in R3): Dedicated IPTV and IMS-Based IPTV. ETSI TISPAN
ITU-T responsible for fostering cooperative standards for telecommunications equipment and systems. 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.” ITU-T IPTV Focus Group and GSI
IPTV Domains: Four IPTV domains are identified including content provider, service provider, network provider and end user. 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). ITU-T IPTV Focus Group and GSI
IPTV Functional Architecture: Functions and functional blocks described in this clause are common to all architectural approaches. ITU-T IPTV Focus Group and GSI
The objective to specify a common and open end-to-end solution for supplying a variety of IPTV and internet multimedia services. OIPF
The pursuit of a single IPTV standard may have failed. • With so many available standards, vendors and operators will need to make hard choices. Conclusion
