An Analysis Quality of Experience and Energy Consumption for Video Streaming via Mobile Devices

Abstract

Due to the huge interest of online video services (e.g., upload, download, streaming) via smartphone, Quality of Experience (QoE) assessment and optimization for video attribute quality has become a key issue. QoE subjective assessment methods based on MOS (Mean Opinion Score) are the most commonly used approaches for defining and quantifying the actual video quality. Although these approaches have been established to consistently quantify users’ level of approval, they do not adequately apprehend which are the important criteria of the video attribute. In this paper, we conducted experiments via multiple devices to measure user’s QoE and energy consumption of video attributes in smartphone devices. The results demonstrate and outline the list of possible solutions in terms of video attributes variation that are relevant and at the same time satisfy the users.
