Abstract

To interpret the impressions of observers, it is necessary to understand the relationship between components that influence perceived video quality. This paper addresses the effect of assessment methodology on the subjective judgement for spatial and temporal impaired video material, caused by video adaptation methods that come into play when there is variable throughput of video material (I-Frame Delay and Signal-to-Noise Ratio scalability). Judgement strategies used are the double-stimulus continuous-quality scale (DSCQS) and the double stimulus impairment scale (DSIS). Results show no evidence for an influence of spatial artifacts on perceived video quality with the presented judgement strategies. Results for the influence of temporal artifacts are less easy to interpret, because it is not possible to distinguish whether the non-linear relation between DSIS and DSCQS appeared because of the temporal artifacts themselves or presented scene content.
