Committed to connecting the world Trondheim, 21 June 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.

Committed to connecting the world Trondheim, 21 June 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.

Committed to connecting the world Trondheim, 21 June 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.
