摘　　要：优质的VR视频观看体验对视频分辨率的要求很高,8K VR保障了画质但需要很大的传输带宽,限制了高画质VR视频的发展。本文首先简要介绍了MPEG OMAF技术标准,随后提出了一套基于FOV编码的8K超高清VR视频端到端系统,该系统采用了基于CMP的映射及FOV的编解码算法,能保障高质量观看的同时极大地降低传输带宽。本文最后详细介绍了系统框架、关键技术以及FOV编码效果,分析了系统的推广应用前景。High-quality VR video experience needs high video resolution.8K VR guarantees picture quality but requires high transmission bandwidth,which limits the development of high-quality VR video.This paper first briefly introduces the MPEG OMAF technical standard,subsequently proposes an 8K-UHD VR Video End-to-End System Based on FOV coding.The system adopts CMP based mapping and FOV based encoding and decoding algorithm,which can ensure high-quality viewing and greatly reduce the transmission bandwidth.Finally,this paper introduces the system framework,key technologies and FOV coding effect in detail,and analyzes the application prospect of the system.
