A QoE-Oriented Control Scheme for Adaptive HTTP Video Streaming in the Wireless Mobile Network

Abstract

HTTP video streaming over the wireless mobile network is challenging because the wireless mobile networking environment usually suffers fluctuation in available bandwidth and mobile users usually keep moving and playing streaming video simultaneously. To deal with the issue, a Quality Of Experience (QoE)-oriented adaptive HTTP video streaming control method based on MPEG-DASH over the wireless mobile networking environment was proposed in this paper. In order to get better QoE, the proposed method considers both temporal and geo concerns for estimating the available bandwidth in the future and the proposed adaptive streaming control scheme considers buffer level, video quality of the most recently downloaded segment and the estimated bandwidth to decide the video quality for the next downloaded video segment. The proposed method has been implemented in the Android system for the client side and the Linux system for the server side. The experiments shown that the proposed method can improve initial delay time, suspended time, suspended times, bitrate difference per segment, and average bitrate difference considering suspending.
