Abstract

Nowadays, due to the expansion of computer networks and the widespread use of services based on them, we are faced with a variety and large number of users, which is why user satisfaction is of great importance. Therefore, quality of user experience (QoE) is important satisfaction metric. QoE is a criterion for measuring the pleasure or annoyance of customer experiences from a service that focuses on the entire service experience. It is a holistic concept, similar to the field of user experience, but has its roots in telecommunications. In video streaming, QoE is referred to as the end user's assessment of the quality of a video service. This concept depends on factors that affect the user experience and were examined and described in this study, including things such as video loading time (buffering), frame rate, bit rate, image resolution, etc. For streaming service providers and content producers, evaluating and optimizing QoE is of great importance because this can have a direct impact on the level of user interaction, retention, and ultimately revenue. QoE is measured through various techniques and metrics, such as buffering rate, video freeze rate, playback start time, and direct user feedback. By identifying weaknesses in this area, video quality and overall user experience can be improved. Given the importance and necessity of the concept of quality of experience in technology management, this study presents an approach to improving the quality of experience of video streams and the influencing factors based on previous studies. In this study, the effect of influencing factors on the quality of user experience has also been investigated and formulated.
