Relationships between Usage Situations and Spatiotemporal QoE in Audio and Video IP Transmission

Abstract

QoE (Quality of Experience) of audio and video IP transmission can change according to users' attributes and usage situations. This paper evaluates the effect of usage situations on QoE from a quality tradeoff point of view. As a usage situation, this paper employs distracted watching; the users watch video and audio while doing a calculation task. We perform a subjective experiment to compare two video output schemes: frame skipping and error concealment. We then find that the task can affect the tradeoff between spatial quality and temporal quality.
