A new Recommendation from SG12 acts as a performance planning tool for videophone
applications taking into account the effects of video as well as voice quality.
The computational model described is for point-to-point interactive videophone
applications including dedicated videophone terminals, desktop or laptop
PCs, PDAs and mobile phones over IP networks.
Recommendation G.1070 gives an algorithm that
estimates videophone quality in terms of quality of
experience/quality of service (QoE/QoS). The model is designed
to be used by QoE/QoS planners to help ensure end-to-end user
satisfaction and to avoid over-engineering at the application, terminal,
and network layers.
