The Effect of Contents and Available Viewpoints on QoE of Multi-view Video and Audio over WebRTC

This paper evaluates the effect of contents and the number of available viewpoints on Quality of Experience (QoE) of Multi-View Video and Audio (MVV-A) transmission utilizing Web Real-Time Communication (WebRTC) media channel, which employs UDP-based transmission into Web technologies. According to viewpoint change requests, this system switches audiovisual streams. We assess QoE through a subjective experiment with various network conditions. In the experiment, we employ two types of contents and two numbers of available viewpoints. QoE is evaluated multidimensionally. We then show that the content and the number of viewpoints affect QoE.
