WebRTC-Based Multi-View Video and Audio Transmission and its QoE
In this paper, we implement a Multi-View Video and Audio (MVV-A) transmission system utilizing WebRTC media channel, which employs UDP-based transmission into Web technologies, to enhance QoE under large delay. According to viewpoint change requests, this system switches audiovisual streams. We compare QoE with MVV-A transmission using MPEG-DASH, which employs HTTP/TCP, through a subjective experiment with various network conditions. As transmission methods utilizing MPEG-DASH, we treat single viewpoint transmission and simultaneous transmission of all the viewpoints. As a result, we find that the MVV-A transmission with WebRTC achieves higher QoE than that with MPEG-DASH under large delay.
