Abstract

We propose a VR video conferencing system over named data networks (NDN). The system is designed to support real-time, multi-party streaming and playback of 360 degree video on a web player. A centralized architecture is used, with a signaling server to coordinate multiple participants. To ensure real-time requirement, a protocol featuring prefetching is used for producer-consumer communication. Along with the native support of multicast in NDN, this design is expected to better support large amount of data streaming between multiple users. As a proof of concept, a protoype of the system is implemented with one-way real-time 360 video streaming. Experiments show that seamless streaming and interactive playback of 360 video can be achieved with low latency. Therefore, the proposed system has the potential to provide immersive VR experience for real-time multi-party video conferencing.
命名数据网络上的VR视频会议
提出了一种基于命名数据网络(NDN)的虚拟现实视频会议系统。该系统旨在支持实时,多方流媒体和360度视频播放的网络播放器。采用集中式架构,使用信令服务器协调多个参与者。为了保证实时性,采用了一种具有预取特性的协议进行生产者和消费者之间的通信。随着NDN对组播的原生支持,该设计有望更好地支持多用户之间的大量数据流。作为概念验证,系统的原型实现了单向实时360视频流。实验表明,该方法可以在低延迟的情况下实现360度视频的无缝串流和交互式播放。因此,该系统具有为实时多方视频会议提供沉浸式VR体验的潜力。
