8. ITU-T Objectives • Develop and publish standards for global ICT interoperability • Identify areas for future standardization by involving academia • Provide an attractive and effective forum for the development of international standards • Promote the value of ITU standards • Disseminate information and know-how • Cooperate and collaborate • Provide support and assistance

9. ITU-T Recommendationsconnect the world… • Without ITU-T standards you couldn’t make a telephone call from one side of the world to another. • E.164 “International public telecommunication numbering plan” • Without ITU-T standards the Internet wouldn’t function. • G.991.x – G.999.x“Recommendations on Access Networks” 9

10. ITU-T Revolutionary video standard • Emmy award received on behalf of ISO, IEC & ITU on 25 August 2008 • Advanced Video Codec ITU-T Rec. H.264 | ISO/IEC 14496-10 • H.264 | MPEG-4 AVC recognized by US Academy of Television Arts & Sciences

11. ITU-T Key Features • Truly global public/private partnership • 95% of work is done by private sector • Continuously adapting to market needs • Pre-eminent global ICT standards body

12. ITU-T is fast (“pre-published” standard = non-edited version  Edited version: typically a few months after approval)

13. ITU-T collaboration • World Standards Cooperation ISO – IEC - ITU • Patent policy & Joint events • ITU-T and IEEE • MoU & Joint events • Global Standards Collaboration • Supports ITU as preeminent global ICT standards organization. • Management meetings with: • ETSI • IETF • ICANN • ISO/IEC JTC 1 • MoU on E-Business: IEC, ISO, ITU and UN/ECE 44 formal partnerships 13

14. New Academia New Ideas Academic Topics for SGs • News • Workshops • Tech-watch • Promotion Industry ITU-T Relevance Other SDOs Regulators New Membership Increased Participation ITU-T and Academia Why Involving Academia? R&D 14

15. How academia has participated so far • Discrete participation in SG activities • Some individuals from academia have leadership roles in ITU-T (Editors, Rapporteurs, chairs of technical committees) • Some participation in Focus Groups and Technology Watch • Some participation in ITU-T workshops • Some important regional activities (e.g. ITU Centres of Excellence) • No specific ITU membership policy for universities  proposal under discussion by ITU Council reduced fee for academia ~2’000 USD 15

16. Why Involving Academia? • Increase academic participation in ITU • Students of today are the people who will shape the technology world of tomorrow • Capture new work (innovations in ICT) for the standardization marketplace. • Universities and R&D institutions are an important pool of innovation. 16

17. ITU-T SG Structure– from WTSA

18. Study Group 12 Mandate • ‘Performance, QoS and QoE’ • Responsible for Recommendations on performance, quality of service (QoS) and quality of experience (QoE) for the full spectrum of terminals, networks and services ranging from speech over fixed circuit-based networks to multimedia applications over networks that are mobile and packet based. Included in this scope are the operational aspects of performance, QoS and QoE. • A special focus is given to interoperability to ensure end-to-end users' satisfaction. • SG 12 is the Lead SG on QoS and Performance

23. Working Party 1/12 Mandate Terminals & multimedia subjective assessment WP1/12 works on transmission characteristics of terminals for fixed circuit-switched, mobile and packet-switched (IP) networks and the related telephonometric methodologies, as well as analysis methods using complex measurement signals. Hands-free communication in vehicles is an important study item. Also addressed are methods, tools and test plans for the subjective assessment of speech, audio and audiovisual quality interactions.

24. Working Party 2/12 Mandate Objective models & tools for multimedia quality The purpose of WP 2/12 is to cover the end-to-end transmission performance of networks, terminals and their interactions, in relation to the perceived quality and its objective assessment as well as guidance and modelling in the field of transmission planning. This includes beside perceptual-based objective methods also parametric models and a framework for diagnostic functions.

25. Working Party 3/12 Mandate Multimedia QoS and QoE WP3/12 is responsible for conducting studies leading to new Recommendations related to multimedia Quality of Service (QoS) and Quality of Experience (QoE) in emerging networks. This includes operational aspects of QoS/QoE, end to end interworking and traffic management, identification of KPIs and QoS metrics for different services, multimedia performance assessment methods and models, and fundamental performance criteria for packet-based networks.
