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.

A study group may be designated by WTSA or TSAG as the lead study group for ITU‑T studies forming a defined programme of work involving a number of study groups. This lead study group is responsible for the study of the appropriate core

Questions has the responsibility, in consultation with all relevant

bodies, to define and maintain the overall framework and prioritize the studies to be carried out by the study groups, and

has to ensure the preparation of consistent, complete and timely Recommendations.

World Standards Cooperation: ISO, IEC, ITU

Established in 2001

Joint initiatives: common text, common patent policy, joint workshops, joint education & training

Regular formal and informal contact of ISO, IEC, ITU leadership

Goal: strengthen and advance the voluntary consensus-based international standards systems of ITU, ISO, and IEC

Avoid duplication and overlap of work

Three weeks ago ITU-T held a Leadership meeting with ISO/IEC JTC 1

Why Involving Academia?

Increase academic participation in ITUStudents 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.
