A revised workplan for some of the Questions in Study Group 12 will include specific mention of IPTV Quality of
Experience (QoE) and Quality of Service (QoS).
The latest meeting of Study Group 12, Geneva, January, also saw
agreement on a definition for QoE. This, experts said, is particularly
important given the inclusion of QoE in the definition of IPTV agreed by the
ITU-T IPTV Focus Group. (See previous story).
of Experience (QoE)
overall acceptability of an application or service, as perceived subjectively by
1 Quality of Experience
includes the complete end-to-end system effects (client, terminal, network,
services infrastructure, etc).
acceptability may be influenced by user expectations and context.
Study Group 12 Vice Chair, Chuck Dvorak, said
that he expects that IPTV and other multimedia QoS and QoE issues will see
increasing attention in SG12 moving forward.
Dvorak also said that he expects that the
non-transport aspects of networks and services, for example call processing
performance, will also receive more attention. Additionally he says that he
expects SG12 will take a closer look at how to better address the needs of
developing countries in terms of QoS.
