Design and implementation of a three-dimensional broadcasting system based on DTV

In this paper, we propose a novel program specific information structure(PSI) in MPEG-2 system for a three-dimensional broadcasting system while guaranteeing compatibility with the conventional digital broadcasting system. The proposed PSI structure including a descriptor of contents type, 2D or 3D, provides service providers with a function of combining 2D and 3D contents freely. However the descriptor is ignored in the conventional digital broadcasting set-top box. With the proposed PSI structure, we designed and implemented a three-dimensional broadcasting system. The proposed system has 2D or 3D display mode for providing user's preference in a three-dimensional broadcasting environment.
