Subjective Evaluation of Quality of Experience for Video Streaming Service

This paper presents the results of the subjective evaluation of Quality of Experience (QoE) for video streaming service. The evaluation was conducted among 602 test subjects who rated the quality of 72 videos by watching them at their homes. The quality of each video was uniquely distorted (packet loss rate, number of packet loss occurrences during video streaming and total duration of those occurrences varied in each video). The results revealed that, in real-life environment, test subjects failed to notice significant number of video segments whose quality was degraded, they could not accurately quantify their total duration and they usually did not maintain negative attitude about perceived quality distortions.
