Abstract: The influence factors on the users’ quality of experience (QoE) in a hypertext transport protocol (HTTP) adaptive streaming system and the interaction between these factors are studied. Then the QoE optimization strategies from the aspects of the server, network transmission and client side are summarized. The QoE optimization of HTTP adaptive live streaming system focuses on reducing delay, and combination with network layer and application layer factors can reduce delay and improve user QoE.
