Abstract:Video delivery over an IT-network is often challenging because bandwidth limitations are bound to affect the quality of experience. In order to reduce bandwidth demand of a video while affecting the QoE as little as possible, parameters like delay, resolution and frame rate need to be optimised with care. While these bandwidth-negotiations have been researched extensively for standalone displays, virtual reality headsets with their special optical properties have barely been assessed in this regard. In this thesis, a video pipeline was created in hardware and software to assess the impact of bandwidth-negotiations on the quality of experience for video viewed in a virtual reality headset. I describe a series of user studies that assess the impact of different video resolutions and video delay on quality of experience and social interaction conducted through virtual reality headsets. The findings described herein are expected to support video distribution of mixed- and virtual reality applications over IT-networks.
