| 摘 要： | 针对基于H．323协议的Openh323开源视频会议系统中源MCU容纳终端有限，图像质量差等缺陷，在VC＋＋6．0开发平台上，采用基于帧缓冲映射软交换技术改进源码中的MCU，提高其存储转发的能力，从而增加参与视频会议的终端；在占用较少CPU资源的同时，有效提高其传输速率，并缩短了传输时延，取得了良好的测试结果。

| Abstract: | The paper deals with the problem that the limit of MCU accepts less endpoints and the poor quality of images-synthesis in Openh323 open source video conferencing system which basing on H323 protocol.It is available to adopt soft exchange with frame-buffer-mapping to improve its stored-and-forward ability and increase more terminal participating in system.While taking the few CPU resources,raising its transmission speed effectively and reducing the transmission delay by use of VC6.0 platform,and getting batt... |
