QoE Approaches for Adaptive Transportof Video Streaming Media

M. SAJID MUSHTAQ, Brice AUGUSTIN and Abdelhamid MELLOUK.

In this chapter, we discuss the different transport approaches for adaptive video streaming media, and how they influence the QoE. These approaches are based solely on the HTTP protocol, and are specially designed for video transportation over the Internet to support the wide range of devices and maximize end user’s perceived quality. The leading groups and companies, e.g. Microsoft, Apple, Adobe and MPEG/3GPP have introduced their own standard approaches to facilitate the on-demand or live adaptive video streaming transport over HTTP. The main goals of adaptive video streaming are to improve and optimize user’s QoE by changing the video quality according to network parameters, end user’s device properties and other characteristics. There are five main quality metrics of video streaming that affect the user engagement during video watching, and influence user’s QoE. The adaptive video streaming approaches use TCP as a transport protocol. Based on network conditions, TCP parameters provide vital information to the client, and streaming is managed by the end-user.
