摘要

In this paper, two questions related to long duration audiovisual content are addressed: firstly, we investigate whether users' quality expectations/requirements develop differently over extended periods of time for different types of content. We have found indicators suggesting that high spatial and temporal activity indices decrease quality requirements over time. Secondly, we show that for long duration content, viewers' quality requirements are independent of magnitude and appearance (gradual increase vs. spontaneous leap) of quality impairments introduced.
