摘要：

As　an　emerging　video　codec　standard　for　multi-view　video　and　corresponding　depth　maps,　three-dimensional　extension　of　High　Efficiency　Video　Coding　(3D-HEVC)　has　broad　application　prospect.　In　order　to　make　the　bit-stream　generated　by　3D-HEVC　suitable　for　emerging　terminal　devices,　reducing　computational　complexity　is　necessary　for　downsizing　resolution　transcoding.　This　article　aims　to　speed　up　3D-HEVC　transcoding.　This　paper　proposes　a　fast　transcoding　algorithm　on　clipping　unnecessary　traversal　depth　level　for　each　CTU.　Experimental　results　show　that　almost　26%　of　computation　time　can　be　saved　for　the　proposed　transcoding　algorithm　with　the　certain　increase　of　BDBR.
