Abstract. There are differences between real and virtual scene information dis-
played on a virtual reality platform, not a true reflection of the reality of the
real-time information. On the basis of virtual reality platform, how to collect,
organize and publish the corresponding real-time virtual reality scene scenes in-
formation is becoming a new problem. In this essay, we will explain how to in-
put, distribute and display real scene information based on the virtual reality
system, a distributed virtual reality system. The current real-time video infor-
mation corresponded with the specified scene object in the virtual reality system
is recorded by the client, released to the streamer server and then distributed via
content distribution server. The live streaming information displayed on the vir-
tual reality client increases the fidelity and real-time of the virtual reality. The
system is timely published, scalable and is capable of supporting remote dep-
loyment and distribution. The goal is to provide a reliable and effective real
scene information dissemination and presentation of the real scene platforms
based on the virtual reality environment.
Keywords: Virtual Reality, Streaming, Virtual Scene and Distribution.
1 Introduction
VR (Virtual Reality) is a computer-simulated environment that can simulate physical
presence in places in the real world or imagined worlds. Most current virtual reality
system focuses on the construction and rendering of reality. However, due to the
problems of modeling, rendering and historical versions, the system does not truly
reflect the information of real-world. The real-time information based on the real
scene displayed and rendered in a virtual reality platform will be very meaningful.
Virtual reality system plays a role not only to simulate the real-world simulations, but
also to release and render real-world information, thereby improving the usability of
the system.
With the popular use of mobile devices, the application based on social relations
such as micro-blog and micro- visual is becoming a new way to publish and broadcast
information. The real-time media increases the speed of information-spreading.
But there is a limitation for expressing the dimension and position of the scene in the
