摘　　要：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.
