360° video streaming has drawn a lot of attention in the last years. In order to provide a good quality of experience with the existing device capability and available bandwidths several viewport dependent techniques have been investigated and developed. One of these techniques, as specified in MPEG OMAF, is to use tile-based streaming, with the 360° video being offered in a tiled manner at various resolutions. Thus, each user can retrieve the tiles at different resolutions, thereby selecting the tiles that match its viewport at high-resolution. This paper provides an analysis on different configurations for tile-based 360° video streaming, comparing the quality that can be achieved by using them for different values of end-to-end delays.
