In this paper we subjectively assess the QoE of AMP with respect to non-periodically and randomly selected content sections of a video sequence by us- ing crowdsourcing. Furthermore, we introduce features that allow to quantify the distortion for audio and video that are caused by increasing or decreasing the playback rate. With these preliminaries we study the correlation between the introduced features and the subjectively assessed QoE. Therefore, we derive a utility model that allows to estimate the QoE with the introduced features. We instantiate and validate the model by the use of the data gathered by the conducted study.}, keywords = {Adaptive Media Playout; Inter-Destination Media Synchronization; Crowdsourcing; Subjective Quality Assessment; Quality of Experience}, language = {EN}, location = {Singapore}, pdf = {https://www.itec.aau.at/bib/files/QoMEX-paper_Rainer.pdf}, talkdate = {2014.09.19}, talktype = {registered} }
