Multidimensional QoE Assessment of Multi-view Video and Selectable Audio (MVV-SA) IP Transmission

This paper deals with Multi-View Video and Selectable Audio (MVV-SA) IP transmission, users can switch not only video but also audio according to a viewpoint change request. We evaluate QoE of MVV-SA by a subjective experiment. The evaluation is performed by the Semantic Differential (SD) method with 13 adjective pairs. In the subjective experiment, we ask assessors to evaluate 40 stimuli which consist of two kinds of UDP load traffic, two kinds of fixed additional delay, five kinds of playout buffering time, and selectable or un-selectable audio (i.e., MVV-SA or the previous MVV-A). As a result, MVV-SA gives higher presence to the user than MVV-A and then enhances QoE. We also conduct factor analysis to clarify component factors of QoE.
