Abstract
The work describes a QoE experiment concerning the assessment of the impact of memory and stimulus variability on subjective assessments of 2D videos, as well as an attempt to identify dominant points − moments in time or events influencing the overall assessment of the changing quality of the assessed films. Based on the results of the conducted QoE experiment, the impact of varying video quality on subjective assessment of 2D videos was clearly demonstrated, both in terms of results eligibility and subjective ratings. The concept of “measurement points” was introduced, i.e., points in time or events that were associated with the highest impact on the values of subjective ratings when variable quality videos are assessed or videos are displayed in variable controlled environment. The relationship between the memory of particular aspects of the video presentation, including the memory of subsequent appearances of the given video, and the values obtained from the assessment results were also demonstrated. There were observed regularities, including very strong negative effect of the variability of the technical quality of the rated videos on results eligibility, effect of boredom/annoyance from watching a longer video of variable quality, “last impression effect”, i.e. videos whose changing quality increases over time achieve higher MOS values than videos whose quality decreases over time and better assessments of “fresh” observations in comparison to the following ones.
