Abstract

Multi-party video conferencing has gained wide popularity, with numerous applications in both formal and informal contexts. With video conferencing being a highly interactive and resource-intensive service, challenges arise in identifying and quantifying the impact of various factors influencing end user Quality of Experience (QoE). In this paper we study QoE for mobile video conferencing, and focus on the impact of different smartphone configurations (differing in CPU, display size, and resolution) on quality ratings. We conduct subjective studies involving interactive three-party audiovisual conversations based on WebRTC technology in a natural environment over a Wi-Fi network with symmetric and asymmetric device conditions. Results clearly show the impact of different device factors on user QoE, and imply minimum smartphone requirements for three-party video conferencing as being a 2.5 GHz processor and 2GB RAM. In addition, we explore user-preferred functionalities available on the conferencing web page which improve overall user perceived quality.

移动设备因素对webbrtc多方视频会议QoE的影响

多方视频会议已经获得了广泛的普及，在正式和非正式的环境中都有许多应用。由于视频会议是一项高度互动和资源密集的服务，因此在识别和量化影响最终用户体验质量的各种因素的影响方面出现了挑战。在本文中，我们研究了移动视频会议的QoE，并重点研究了不同智能手机配置(CPU、显示尺寸和分辨率不同)对质量评级的影响。我们进行了基于WebRTC技术的交互式三方视听对话的主观研究，在自然环境下通过Wi-Fi网络在对称和非对称设备条件下进行。结果清楚地显示了不同设备因素对用户QoE的影响，并暗示三方视频会议对智能手机的最低要求是2.5 GHz处理器和2GB RAM。此外，我们还探讨了会议网页上的用户首选功能，这些功能可以提高用户的整体感知质量。
