This paper investigates QoE (Quality of Experience) of MVV (Multi-View Video) and audio transmission over IP networks. Unlike previous works that mainly discuss MVV transmission from aspects of video codecs, the authors study MVV and audio transmission under various IP traffic and delay conditions by experiment. They compare two schemes: a scheme that the user watches a single viewpoint, and the one that he/she can choose one viewpoint from many viewpoints. At the same time, they perform a user study which helps them to understand the user behavior in the MVV system under those conditions. As a result, they show that high QoE can be achieved when the user can change the viewpoint with low load traffic and delay.
