Video Streaming

This chapter addresses QoE in the context of video streaming services. Both reliable and unreliable transport mechanisms are covered. An overview of video quality models is provided for each case, with a focus on standardized models. The degradations typically occurring in video streaming services, and which should be covered by the models, are also described. In addition, the chapter presents the results of various studies conducted to fill the gap between the existing video quality models and the estimation of QoE in the context of video streaming services. These studies include work on audiovisual quality modeling, field testing, and on the user impact. The chapter finishes with a discussion on the open issues related to QoE.
