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.
