Tiled panoramic video transmission system based on MPEG-DASH

Abstract

This paper presents a panoramic video transmission system using spatially divided tiles based on the spatial relationships descriptions of MPEG-DASH. The proposed server system provides tiling and encoding functionalities for ROI-based retrieving. Moreover, it guarantees the temporal and spatial synchronization when rendering multiple tiles by a deterministic tile size and intra-coded frames at the starting of all segments. Finally, we conduct a performance evaluation with panoramic videos at the eight HD-quality to show the feasibility of the tile-based transmission.
