  The recent rise of interest in Virtual Reality (VR) came with the
availability of commodity commercial VR prod- ucts, such as the Head Mounted

platforms. In this study, we try to cover different aspects related to VR
content representation, streaming, and quality assessment that will help
establishing the basic knowledge of how to build a VR streaming system.
