Abstract

Delivering high resolution, high bitrate panorama
video to a large number of users introduces huge scaling
challenges. To reduce the resource requirement, researchers have
earlier proposed tiling in order to deliver different qualities in
different spatial parts of the video. In our work, providing an
interactive moving virtual camera to each user, tiling may be used
to reduce the quality depending on the position of the virtual
view. This raises new challenges compared to existing tiling
approaches as the need for high quality tiles dynamically change.
In this paper, we describe a tiling approach of panorama video
for interactive virtual cameras where we provide initial results
showing the introduced overheads and the potential reduction in
bandwidth requirement.
