Novel distributed virtual reality architecture based on streaming techniques

Abstract

There exist irreconcilable conflict between mass data and network transfer bandwidth in traditional distributed virtual reality (DVR) systems, which has severely limited the widespread application of DVR techniques. In order to solve these problems, a novel DVR system architecture based on streaming techniques is proposed. The topology of this system is a hybrid architecture (using peer-to-peer model to transfer control information, using hierarchy model to transfer data information), which is helpful to overcome the communication bottle-neck, and the object-oriented data structure is also designed to fit for streaming techniques. In order to take full advantage of streaming techniques, multithreading and dynamic buffer can be applied to reduce network time-delay. In this paper, the implements of these techniques are introduced in detail, the result of experiments prove that: the DVR system based on streaming techniques can notably reduce the hardware requirements, increase the client number and decrease the system time-delay, as a result make the internet based desktop DVR system available.
