Abstract
In this paper, we propose a tile quality selection method in tile-based video streaming. The proposed method suppresses the spatial quality variation within viewport caused by the change of the viewport region due to the movement of the user’s head. In the proposed method, client checks whether the difference of quality level between viewport and around viewport is large. When assigning quality, if the difference of quality level between the viewport and around viewport is large, the difference is reduced. As a result of simulation, when the segment length is long, quality variation can be suppressed without significantly reducing the perceived bitrate. Especially, the quality variation within viewport can be greatly suppressed.
