摘要： 元宇宙教育将元宇宙应用于教育领域,为学生创造丰富多样的学习场景和资源,提供个性化的学习推荐和指导。在元宇宙场景中,可以通过边缘计算技术提升音视频传输性能和降低通信成本,包括远程控制时延的降低、终端设备能效提升等。因此,针对VR,AR教育交互场景中的设备成本高、通信时延大等问题,提出了基于边缘计算和WebRTC的通信技术方案,解决教育场景下大量用户接入造成网络拥塞的问题,构建元宇宙教育的基础通信设施。通过云端所部署的Unity渲染平台,在边缘端部署WebRTC多用户通信模块,实现极低延迟的视音频传输,提升移动边缘平台的传输性能。最后,构建云边端协同的音视频传输系统,通过实际的边缘计算传输策略和端到端实验验证,实现了低时延、高性能的元宇宙教育系统,且验证了元宇宙教育场景的可行性。

Abstract: Metaverse education applies the meta-universe concept to the field of education,creating diverse learning environments and resources for students,and providing personalized learning recommendations and guidance.In the meta-universe scenario,performance can be enhanced and costs reduced through edge computing technologies,including the reduction of remote control latency and increased efficiency of terminal devices.To address challenges such as high device costs and significant communication latency in VR,AR education interaction scene,a communication technology solution based on edge computing and WebRTC is proposed.This solution aims to resolve congestion issues caused by a large number of users accessing educational scenarios,establishing the foundational communication infrastructure for meta-universe education.Leveraging a unity rendering platform deployed in the cloud and a WebRTC multi-user communication module deployed at the edge,the system achieves extremely low-latency audio-visual transmission,enhancing the transmission performance of mobile edge platforms.Ultimately,a cloud-edge collaboration audio-video transmission system is constructed.Through specific edge computing transmission strategies and end-to-end experimental validation,a meta-universe education system with low latency and high performance is realized.Experimental verification confirms the feasibility of metaverse education scenarios.

Key words: Metaverse education, Virtual reality, Edge computing, Cloud synergy, WebRTC
