Description
Summary:In this paper, we present descriptions for 3D stereoscopic video conversion that can be utilized in MPEG-21 digital item adaptation. Our description tools provide a functionality of description of user characteristics and terminal capabilities. In particular, the description of user’s display presentation preferences supports 3D stereoscopic conversion of 2D video (2D/3D video conversion) as well as 2D conversion of 3D stereoscopic video (3D/2D video conversion) so that users can enjoy either 2D or 3D stereoscopic video they prefer. Furthermore, we investigate the effects of the type of parallax, the range of depth, and the maximum interval of a delayed frame on the perception of 3D depth. The syntax of the descriptions and their elements is represented in eXtensible Markup Language schema, and their feasibility has been examined and verified in our experiments, where MPEG test sequences are adopted for 2D/3D video conversion. On the contrary, ordinary stereoscopic test video is used for 3D/2D video conversion.
