Determination of the Impact of Video Encoding Parameters on QoE Using Passive Viewing Tests

Optimizing video encoding parameters is essential for cloud gaming service providers to deliver high-quality gaming experiences to their users. In this study, we conducted a passive Quality of Experience testing on a publicly available dataset of cloud gaming sessions to evaluate the impact of video encoding parameters on the Quality of Experience ratings of the samples. Participants assessed the quality of video streams utilizing a selected methodology, and statistical analysis was conducted to ascertain how various parameters affected the average quality ratings of diverse game genres. We further investigated the impact of quality settings on the participants’ willingness to play. Additionally, we explored the applicability of passive viewing tests by comparing our QoE analysis results with previous research that used active viewing tests in cloud gaming evaluations.
