This paper presents an approach for 3D video coding that uses a format in which a small number of views as well as associated depth maps are coded and transmitted. At the receiver side, additional views required for displaying the 3D video on an autostereoscopic display can be generated based on the corresponding decoded signals by using depth image based rendering (DIBR) techniques. In terms of coding technology, the proposed coding scheme represents an extension of High Efficiency Video Coding (HEVC), similar to the Multiview Coding (MVC) extension of H.264/AVC. Besides the well-known disparity- compensated prediction, advanced techniques for inter-view and inter-component prediction, the representation of depth blocks, and the encoder control for depth signals have been developed and integrated. In comparison to simulcasting the different signals using HEVC, the proposed approach provides about 40% and 50% average bit rate savings for a whole test set when configured to comply with a 2- and 3-view scenario, respectively. The proposed codec was submitted as response to a Call for Proposals on 3D Video Technology issued by the ISO/IEC Moving Picture Experts Group (MPEG) and it was ranked as the overall best performing HEVC-based proposal in the related subjective tests.
