　　内容简介：

　　New generation mobile networks evolving from LTE to 5G have expanded the system capacity at a faster rate than ever, but are still facing tough challenges such as in achieving ultra-reliable and low-latency communication (URLLC) and the required level of quality of experience (QoE), especially for rich media applications such as video streaming. Cisco has reported that video traffic in mobile networks is rising at a 90% annual growth rate and has been the dominant traffic in any type of networks. Ensuring QoE has become a major goal of service providers and network operators for mobile media delivery which is highly bandwidth consuming and subject to wireless channel constraints. Therefore, developing effective quality metrics is currently one of the research focuses of video technologies and services. In this seminar, a review of the existing methods for quantifying the quality of video streaming is given, providing the audience with knowledge on traditional quality assessment technologies as well as the latest developments of QoE based quality assessment in streaming services with both theoretical and practical aspects.
