摘要
VR全景视频沉浸式观看是VR全景视频技术的重要代表性特征,同时也是VR全景视频技术发展和在各行业普及应用的决定性影响因素之一。随着广电用户对视觉观看体验要求的日益提高,必须思考和分析VR全景视频技术链路各环节对观看的影响。本文首先对VR全景视频端到端系统链路进行简要介绍,之后着重分析视频源、传输编码和终端渲染显示三个环节对视觉观看体验的影响,并经梳理归类得出较为舒适的观看视觉体验在各环节所需要的技术要求。
Immersive viewing is the most important representative feature of VR panoramic video technology.At the same time,it is also one of the decisive influencing factors for the development of VR panoramic video technology.With the increasing demand of high visual viewing experience for audiences,we need to analyze the various aspects of VR panoramic video technology on viewing experience.This paper firstly introduces the technical procedure of VR panoramic video,and then focuses on the video source,map encoding,transmission,terminal receiving and rendering.At last,we conclude technical requirements of VR panoramic video for comfortable visual viewing experience.
