多点控制单元(MCU)是视频会议系统中一个非常重要的组成部分,但在目前的系统中一般均采用硬件来实现。给出了主席控制模式下MCU的软件实现,并且给出了MCU的相关性能。与硬件方式相比,用软件实现MCU具有节省系统费用和更加灵活的优势。
Multipoint Control Unit (MCU) is a video conferencing system is a very important part, but in the current system are generally used to achieve the hardware. The software implementation of MCU in chairman control mode is given, and the related performance of MCU is given. Compared with the hardware approach, MCU software implementation has the cost savings and more flexible advantages.
