Abstract: Consumers demand video delivery to a wide variety of multimedia capable playback devices in dissimilar contexts. Monitoring the quality of the network provides a preliminary indication of the video quality end-users can expect. However, more advanced measurements are needed to reliably predict perceived quality. In this paper, we provide information on how to measure video quality, from leveraging fundamental and pure network measurements all the way to modeling and measuring perceived video quality. Currently, video quality research is migrating towards measuring Quality of Experience and User Experience, which is known to be highly subjective and dynamic. Therefore, we also present and discuss the research challenges resulting from this change in focus in more detail.

Keywords: subjective testing; video quality metrics; quality of experience (QoE); user experience (UX)
