Subjective and Objective QoE Measurement for H.265/HEVC Video Streaming over LTE

Abstract

Mobile video traffic is the fastest growing segment of mobile data driven by proliferation of devices with larger screens and higher resolution, as well as increased network performance achieved through long term evolution (LTE) deployments. Emerging video formats and applications, such as H.265/high efficiency video coding (HEVC) will increase the video traffic consumption while improving the user quality of experience (QoE). Although QoE is affected by many influence factors (IFs), this paper focuses on media-related system IFs and their impact on subjective and objective QoE metrics for H.265/HEVC video streaming. The aim is to examine the impact of media-related system IFs on QoE for video streaming and compare the results of subjective and objective QoE measurements. Results obtained from experimental study are used to analyze the relationship between subjective and objective QoE metrics for H.265/HEVC video streaming.
