3 About ITU and its standardization work 3

4 About ITU The United Nations Specialized Agency for Information and Communication Technologies (ICTs) Founded in Paris in 1865 as the International Telegraph Union 2015 will mark 150 years of experience and innovation 4

5 ITU s Global Presence 5

6 ITU s Structure Radiocommunication ITU-R Coordinates global wireless communication Standardization ITU-T Development ITU-D Produces interoperable technical ICT standards Provides assistance to the un-connected The General Secretariat provides intersectoral coordination for the whole organization 6

7 ITU-R: Radiocommunication Sector Manages the radio-frequency spectrum and satellite orbits 7

8 ITU-D: Development Sector Assists the development of ICTs in the developing world 8

9 ITU-T: Standardization Sector Produces standards* covering all fields of telecommunications on a worldwide basis, and defines tariff and accounting principles for international telecommunication services * ITU Standards are called "Recommendations" 9

10 ITU-T Key Topics Internet Broadband Access (xdsl, G.fast, Fiber to the x, Powerline communication) Transport and Optical Fiber Multimedia (video coding: ITU-T H.264 and H.265) IPTV, Smart Cable Television Numbering and Identification Resources Conformance and Interoperability Testing ICT Accessibility and human factors 10

11 ITU-T Key Topics Performance, Quality of Service (QoS) and Quality of Experience (QoE) Software-defined Networking (SDN) Cloud Computing Big Data M2M and Internet of Things (IoT) Cybersecurity, Identity Management, Child Online Protection 11

12 ITU-T Key Topics Intelligent Transportation Systems (ITS) Smart Grid E-Health ICT and Climate Change, Smart Sustainable Cities, Smart Water Management Emergency Communications, Disaster Relief Systems, Network Resilience and Recovery Bridging the Standardization Gap 12

13 ITU s Membership 193 Member States and Regulatory Bodies 750 Companies, Business Associations, NGOs 66 Universities & Research Establishments (in 41 countries) 13

14 A sample of ITU s private sector members 14

15 Why standards? 15

16 PAUSE What is a standard, anyway? Sensu lattu : dominant designs called as "standards" "Standards" versus "Formal Standards" Formal standards are accepted on a global basis ISO, IEC, ITU Standards [ISO] Standards are documented agreements containing technical specifications or other precise criteria to be used consistently as rules, guidelines or definitions of characteristics, to ensure that materials, products, process and services are fit for their purpose Developed by Consensus 16

17 Importance of global standards Drive competitiveness for individual businesses and world economy; increase choices for consumers Manufacturers, network operators, service providers and consumers benefit Lower prices; lower risk Reduce technical barriers Multilateral agreements rather than bilateral Foster interoperability Reduce negative impacts on the environment 17

18 Open standards promote a "network effect" 18

19 Media platforms and IPTV 19

20 Media platforms Broadcasting ITU-R Study Group 6 ITU-R BS-Series Traditional broadcasting IBB - Integrated Broadcast-Broadband Cable ITU-T Study Group 9 ITU-T J-Series (DOCSYS) IPTV ITU-T Study Group 16 ITU-T H.700-series 20

21 ITU IPTV Standards Content delivery over managed IP networks May include, but is not focused on Internet-sourced / delivered content Enablers: broadband access and next generation networks Toolbox concept: modular elements for building interoperable but customizable systems Richer services and user experience Good deployment Globally, 45.4 million at the end of 2010 (Point Topic, IPTV Q Short Report) Japan in particular (4 million devices: 10% of global market) 21

22 Overview of ITU-T Recommendations for IPTV End-user functions and application functions are hot topics now Many draft Recommendations and Technical Papers under discussion Home networking Applications and end-systems H.622.1: Req & Arch for IPTV Home networks Architecture, requirements, network H.750: Metadata for IPTV Services H.721: IPTV Terminal (Basic) H.722: IPTV Terminal (Advanced) H.770: IPTV Service discovery H.761: Ginga-NCL H.751: Rights H.741.x: Audience Measurement management H.762: LIME H.763.1: Cascading style sheets for IPTV services H.264, H.265: video Quality of experience Y.2007: NGN Capability Set 2 H.701: Content Error-Recovery Y.Sup 5: IPTV Service use cases G.1080: IPTV QoE Y.Sup 7: NGN Release 2 Scope G.1081: Performance Monitoring Y.1910: IPTV Functional Architecture G.1082: Improving robustness of IPTV performance Y.1901: IPTV Service Requirements Q.3010: Authentication protocol Security and Content Protection X.1911: Req & arch for IPTV security 22

23 IPTV is more than TV over IP Yes: Linear TV, VoD Quality of experience assurances Service discovery Security & conditional access Interactivity is a key feature Multi-device for forking experience App-able: rich services to subscribers E-health, e-gov, education, public safety, Next-generation audience measurement: more monetization opportunities more customizable experience 23

24 E-health app IPTV widget Server Hub working as gateway Normal programme ITU-T H.810 Blood pressure meter I2R, NTT Pedometer Scale Widget implemented with LIME (ITU-T H.762) for e-health information collected from the user site, consolidated in the server backend and displayed on users IPTV terminal device as a widget. 24

25 Accessibility standardization in ITU 25

26 Why accessibility? Increasing number of countries ratifying UN Convention on rights of persons with disabilities Consequences in legislation & regulation It goes beyond persons with disabilities Children, functional illiterate, elderly, Mainstreaming is important: Human rights Societal efficiency Drives down cost, increases user base An unanswered question: How to provide accessible AV content in a cost effective manner? Standards! 26

27 ITU standards groups for accessible ICT s Expert Groups Study Group 16 - Multimedia - lead ITU study group on telecommunication/ict accessibility for persons with disabilities - [Question 26/16] Also on media coding, IPTV, e-health, IoT, ITS Study Group 2 on Operational Aspects Question 4/2 focuses on human factors Intersector Rapporteur Group on Audiovisual Media Accessibility (IRG-AVA) New crosssector experts group with ITU-T and ITU-R experts 27

28 Some current AV media work items Terminology of accessibility to audiovisual media Accessibility features for mobile media devices Technical Paper on methods for improving the intelligibility of audio (or speech) Making AV content accessible: Guidelines for captioning, audio descriptions, sign language, etc. 28

29 A recent ITU workshop ITU Workshop on Making Media Accessible to all: the options and the economics Workshop to review existing as well as next- generation accessibility services and technologies in the audiovisual media sphere, business cases of accessibility-service rollouts from across the world Demos on accessibility services currently on the market and under development by private-sector players and research institutes. 29

31 Conclusions 31

32 Conclusions ITU IPTV Recommendations will encourage innovation, ensure interoperability and ultimately help players remain competitive They are enablers of innovation on broadband and Next Generation Networks ITU IPTV standards are already implemented and deployed (e.g. H.721) Turnkey solutions already exist Open architecture in ITU IPTV standards Truly global & open standards that can be deployed across a wide range of applications Mainstreamed, standards-based solutions to AV media accessibility becomes an economic imperative Regulations, legislation Many side benefits for the public at large, but also great opportunities for content and service providers Standards-based IPTV can be an enabler for accessibility 32

33 Thank You! (T) (F) ITU / Place des Nations CH1211 Geneva 20 Switzerland Simão Ferraz de Campos Neto joined the secretariat of the ITU Standardization Sector in 2002, and is the Counsellor for ITU-T Study Group 16 (for standardization work on multimedia services, protocols, systems, terminals and media coding, including accessibility, IoT, IPTV and Digital Signage). He organized several workshops (e.g. Multimedia in NGN, Telecoms for Disaster Relief, RFID, E-health standards; SIIT2005) and was the editor of the first version of the ITU-T Security Manual. Prior to joining ITU in 2002, Mr Campos worked for 8 years as a scientist in COMSAT Laboratories performing standards representation and quality assessment for digital voice coding systems, and before that he was a researcher at Telebras s R&D Center (CPqD). A Senior Member of the IEEE, Mr Campos authored several academic papers and position papers, served in the review committee of several IEEE-sponsored conferences, and organized the first ITU Kaleidoscope Conference. 33
