摘要
合成虚拟空间会议系统 (VST)的一个需要考虑的重要因素是混频器数量和混频时延的关系 ,其中混频器数量影响系统的成本 ,而混频时延影响系统的实时性 ,降低系统的混频时延和降低混频器数量是一对矛盾的问题 基于VST系统的通信效率与混频器关系 ,提出了在保证系统通信容忍的时延情况下 ,选取最少的混频器数量 ,以及在分层结构中系统通信的最小时延策略
An important factor which needs to be considered in composing a virtual space teleconferencing system is the relation between the amount of the mixer and the mixing time delay The amount of the mixer can affect the system's expense and the mixing time delay can affect the system's ability of real time communication It is a contrary technology between reducing the mixing time delay and reducing the mixer's quantity in VST Given in this paper is a method about selecting the mixer's smallest quantity under the condition of permitting time delay in the VST, which can ensure that both high efficiency and lower price can be supported in the VST system
