Abstract

As internet video applications, especially HTTP Adaptive Streaming (HAS), gained their popularity all around the world, monitoring and assessment technologies of video-related quality of experience (QoE) were going hot during the last few years. The paper introduces the system architecture and procedures that support HAS video application, and analyses the difference of QoE technologies between traditional streaming video and HAS video. It also reviews the QoE models for current video services, and spots the possible future research directions and challenges, from point of view of client, network and server, respectively, on how HAS QoE would be built and applied in practical employment.
