综述3DTV系统的3种类型，包括基于双目的3DTV、基于多视的3DTV和由2D视频转换为3D视频的3DTV系统，并在概述各自实现方法的基础上，指出相应的优缺点.对作为今后发展主流的多视3DTV系统，分析其尚需突破的三方面关键技术，并进一步介绍有利于解决这些关键技术的以“多视+深度”表示的3DTV新模式，以及课题组对此新模式所取得的研究进展.最后，对3DTV系统的发展和应用前景进行展望.

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.
