Measuring Quality of Experience of Novel 360-Degree Streaming Video During Stalling

Abstract

With the rapid growth of novel 360-degree video streaming applications, there has been a strong demand of quality-of-experience (QoE) measurement. For the novel experience provided by the 360-degree video, there still lack of corresponding research and usable evaluation model. In this paper, the user’s QoE during the stalling event for the 360-degree streaming video viewed on the Virtual Reality (VR) Head-Mounted Display (HMD) is obtained for the first time by an elaborately designed subjective experiment. The impact of stalling event on the QoE of 360-degree video streaming is then investigated. We find that there is a significant difference between the QoE during the stalling for the 360-degree video streaming and the traditional video streaming, which indicates that the existing QoE evaluation models are no longer suitable for evaluating the QoE of 360-degree video streaming. This preliminary finding appeals for more researches on modeling the specific QoE of 360-degree video streaming.
