用户聚集场景下的超高清VR视频渲染计算优化

The Optimization of UHD VR Video Rendering Calculation in User Clustered Scenes

超高清虚拟现实(Virtual Reality,VR)视频的高分辨率和用户聚集场景的频繁交互都需要视频的高效渲染。目前,移动设备计算资源和公有带宽的限制导致设备无法为用户提供低时延、高交互的视频渲染计算服务。对此,提出一种去中心化的分布式渲染计算服务机制,旨在通过多移动设备协同构建渲染计算服务网络,为聚集场景下的用户提供优质的服务。还提出一种协同服务数据共享层构建方法,解决移动设备业务随机性给数据共所带来的问题。这种去中心化的协同分布式服务和共享机制,可为超高清VR视频业务提供良好的技术支撑,促进移动视频业务交互模式的创新。

The high resolution of ultra high definition Virtual Reality(VR)videos and the frequent interaction of user aggregated scenes require efficient video rendering.At present,the limitations of mobile device computing resources and public bandwidth prevent devices from providing users with low latency and high interaction video rendering computing services.In this regard,this article proposes a decentralized distributed rendering computing service mechanism,aimed at building a rendering computing service network through multiple mobile devices to provide high-quality services for users in aggregated scenarios.A collaborative service data sharing layer construction method is also proposed to solve the problem of data sharing caused by the randomness of mobile device business.This decentralized collaborative distributed service and sharing mechanism can provide good technical support for ultra-high definition VR video business and promote innovation in the interaction mode of mobile video business.
