Kurzbeschreibung | The visual cortex of the human brain can assess the perceived quality of a video sequence within split seconds. As this information is very valuable for video encoding and transmission schemes, Quality of Experience (QoE) models were developed. Based on these models, the QoE literature has identified two major groups of influence factors on the user perceived experience:
Currently, there are models relying on the first or second group of input parameters exclusively to estimate a video’s QoE. However, this view on QoE is not exhaustive: usually, varying image quality and stalling happen within video sessions at the same time. Moreover, rising Video on Demand services such as Netflix often apply a pay per use model for the content, which can be assumed to be influential. A joint model taking all the discussed parameters into account would provide valuable insights for video distribution services. In this thesis, we plan to create a holistic QoE model based on user studies. Therefore, the following steps are foreseen:
