Multi-view Video Coding Based on High Efficiency Video Coding

Multiview video coding is one of the key techniques to realize the 3D video system. MPEG started a standardization activity on 3DVC (3D video coding) in 2007. 3DVC is based on multiview video coding. MPEG finalized the standard for multiview video coding (MVC) based on H.264/AVC in 2008. However, High Efficiency Video Coding (HEVC) which is a 2D video coding standard under developing outperforms the MVC although it does not employ interview prediction. Thus, we designed a new multiview video coding method based on HEVC. Interview prediction was added into HEVC and some coding tools were refined to be proper to MVC. The encoded multiple bitstreams are assembled into one bitstream and it is decoded into multiview video at decoder. From experimental results, we confirmed that the proposed MVC based on HEVC is much better than H.264/AVC, MVC, and HEVC. It achieves about 59.95% bit saving compared to JMVC simulcast at the same quality.
