From QoS to QoE A Tutorial on Video Quality Assessment. application scenarios [4]. For video transmission, quality of experience (QoE) is an effective subjective quality assessment model for the perceptual visual quality of video sequences. One of the most widely used QoE metric is the Mean Opinion Score (MOS) [5]. In the MOS model, the visual quality of a video sequence is not only dependent, 1914 IEEE JOURNAL ON SELECTED AREAS IN COMMUNICATIONS, VOL. 34, NO. 6, JUNE 2016 results in suboptimal quality of experience (QoE), especially for short video clips, because of the following two reasons. We further conducted user assessments to compare the performance of IRate and the predefined approach in terms.

That is, how resilient is a game's QoE against network impairment. The network robustness property can be observed from the relationship between a game's QoE score and the corresponding network setting.
