Video streaming is one of the major applications of the Internet and accounts for a large portion of the Internet traffic. In particular, Video On Demand (VOD) streaming services using Dynamic Adaptive Streaming over HTTP (DASH), etc., are flourishing, and its viewing comfort is an important factor in various Quality of Experience (QoE) metrics. The startup delay, which is the time from the user's instruction to the video playback actually starting, is a particularly important factor. It has been reported that an increase in the startup delay not only impairs the QoE but also causes users to stop using video streaming services. In order to reduce the startup delay, it is necessary to clarify the impact of network quality and establish guidelines for service design and operation. Although throughput, which directly affects the download time of video content, is an important factor in network quality, actual video streaming services involve not only downloading of video content but also various transactions for preparation and control of video streaming. These transactions may have a large impact on the startup delay. In this paper, we focus on round-trip time as a factor of network quality that determines the startup delay of video streaming, and evaluate the impact of increasing or decreasing the round-trip time on the startup delay by measuring it using actual equipment. |
