Abstract
The moving picture experts group (MPEG) immersive video (MIV) coding standard enables the implementation of a practical six degrees of freedom (6DoF) virtual reality (VR) video streaming system by two approaches: 1) removing the redundancy between multi-view videos or 2) selecting and transmitting representative views among multi-view videos using traditional 2-D video compression standards. This paper presents a strategy for providing immersive video considering two aspects: 1) minimizing the fatigue in the synthesized and rendered viewport, and 2) providing rate-distortion optimization (RDO) to yield high-quality videos at a low bitrate. The results of the two approaches in the MIV coding standard using high-efficiency video coding (HEVC) are discussed, and the advantages and drawbacks of each method for 2-D display and head-mounted display are detailed.
