Videophone services over IP (Internet protocol) will become key services in the next-generation network (NGN). To provide a high-quality service for users, designing and managing the quality of experience (QoE) appropriately is extremely important. To do this, developing an objective quality assessment method that estimates subjective quality by using quality parameters of the videophone system is desirable. We propose a parametric-planning model for assessing video quality affected by coding and packet loss. The results indicated quality estimation accuracy was sufficient for practical use because the estimation errors of our model were equivalent to the statistical reliability of subjective assessment. Therefore, our model could be applied to effective design of video quality for videophone applications and networks. As an example of using our model, we show video-quality planning of videophone services.
