综述了基于高效率视频编码HEVC（high efficiency video coding）标准的两种扩展，即MV-HEVC （high efficiency video coding based multiview）和3D-HEVC（high efficiency video coding based 3D video coding）的工作原理及其编码工具，分析了3D-HEVC 模型的特点、编码模块与方法，并将3D-HEVC与MV-HEVC进行了性能对比。总结发现，由于3D-HEVC 采用纹理视频加深度格式来合成虚拟视点，从而降低了大量的编码码率，可方便应用于3D电视、自由立体视点电视和3D数字电影等多种三维体验中。随着智能移动设备的发展，手持终端采用3D-HEVC支持多视点3D视频将会成为未来的研究趋势。

The operating principle and coding tools of two kinds of extension of HEVC (high efficiency vid-eo coding)standards including MV-HEVC (high efficiency video coding based multiview)and 3D-HEVC (high efficiency video coding based 3D video coding)were reviewed.The feature,coding modules and method of 3D-HEVC model were analyzed,and the performances between 3D-HEVC and MV-HEVC were compared.The conclusion showed that 3D-HEVC synthesized virtual view with the format of texture video plus depth,thus its bit rates would be reduced notably,so 3D-HEVC would be applied to many kinds of 3D experience like 3D TV,free viewpoint video and 3D digital movie.With the development of smart mobile devices,handheld terminal using 3D-HEVC to support multiview 3D video would become the research tend-ency in the future.
