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.
