An Overview of IPTV Standards Development Chih-Hsiang Chou Advisor: Prof Dr. Ho-Ting Wu Department of Computer Science and Information Engineering, National Taipei University of Technology Taiwan, ROC. Data:12/05/29 Outline IPTV Introduction IPTV Standards Development Organizations DVB ETSI TISPAN ITU-T OIPF Conclusion References 2 IPTV Introduction 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. 3 IPTV Introduction IPTV features Support for interactive TV Time shifting Personalization Low bandwidth requirements Accessible on multiple devices 4 IPTV Introduction 5 IPTV Introduction 6 IPTV Introduction 7 IPTV Introduction 8 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. 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 2008. The goal of the handbook is to specify technologies on the interface between an IP network and a Home Network End Device (HNED). 11 DVB 12 DVB 13 DVB 14 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 2008. There are two variants of IPTV in TISPAN R2 (and also in R3): Dedicated IPTV and IMS-Based IPTV. 15 ETSI TISPAN 16 ETSI TISPAN 17 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 (NonNGN 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 References [1] Julien Maisonneuve, Muriel Deschanel, Juergen Heiles, Wei Li, Hong Liu, Randy Sharpe, and Yiyan Wu. “An Overview of IPTV Standards Development”, IEEE Transactions on Broadcasting, Vol. 55, No. 2, pp. 315-328, 2009.
