Following the success of the audio video standard(AVS) for 2D video coding,in 2008,the China AVS workgroup started developing 3D video(3DV) coding techniques.In this paper,we discuss the background,technical features,and applications of AVS 3DV coding technology.We introduce two core techniques used in AVS 3DV coding:inter-view prediction and enhanced stereo packing coding.We elaborate on these techniques,which are used in the AVS real-time 3DV encoder.An application of the AVS 3DV coding system is presented to show the great practical value of this system.Simulation results show that the advanced techniques used in AVS 3DV coding provide remarkable coding gain compared with techniques used in a simulcast scheme.
