The impact of bandwidth limitations and video resolution size on QoE for WebRTC-based mobile multi-party video conferencing
Multi-party video conferencing is a highly delay-sensitive and resource-intensive service. A key challenge faced by service providers is meeting end user Quality of Experience (QoE) requirements given bandwidth limitations, especially in mobile networks. Service adaptation mechanisms may thus be employed to adapt the audiovisual quality so as to meet current network conditions and resource availability. In this paper we report on a subjective user study involving three-party audiovisual conversations established via mobile devices and aimed to investigate the impact of different video resolutions on QoE. We also investigate how different bandwidth limitations impact QoE for different video resolutions. The calls were established using a Web-based Real-Time Communication (WebRTC) application running on the Licode Multipoint Control Unit.
