Abstract: This paper introduces three types of 3DTV systems including twoview 3DTV, multi-view and 2D-3D systems. Based on the description of key components, the merits and drawbacks of each system are analyzed. A new method, i.e., view-plus-depth, to represent 3D scenes, which can effectively reduce 3DTV data for transmission is described. Finally, the procedure of 3DTV development is presented and the prospect of homeoriented 3DTV application is given.

Key words: video compression, 3DTV, depth
