Tiivistelmä

Omnidirectional video is more and more widespread in consumer electronics and professional capture devices, as well over Internet via novel streaming services. Omnidirectional video requires a large streaming bandwidth. To date there is little knowledge about the subjective experience of streaming services of omnidirectional video. The aim of this paper is to present subjective assessment results of experiments using a tilebased streaming system for omnidirectional video with the goal of reducing the streaming bandwidth. The results we present show that it is possible to reduce streaming bit rates by an average of 44% for a subjective DMOS value of 4.5 for different content genres.
