User study of the subjective quality of mobile streaming service

Abstract

The number of smartphone users has increased markedly in recent years. They enjoy multimedia services, such as video streaming, unconstrained by time and place. However, mobile streaming services require a high throughput, and may have an impact on network capacity. The control of service quality is important from both the perspective of user experience and network quality. However, the quality of a video service has mainly been evaluated by examining the picture quality. It is less common to use a network design viewpoint to evaluate video streaming services. In this paper, we discuss the subjective quality of streaming video on mobile terminals. The main contribution of this paper is to quantitatively show the relation between the overall satisfaction, network quality and picture quality, based on the results of the user study.
