摘要
针对视频会议系统的主要关键技术及应用问题,构建了一种高性价比的视频会议系统;采用嵌入式技术,充分利用软件技术与虚拟仪器技术的强大功能,实现了MCU的小型化,降低了系统成本。测试结果表明,该系统支持标准H.323协议、支持最新的H.264编码标准和H.239双视频流、支持广泛的网络协议,界面友好,性能稳定,具有较高的实用价值。
According to the key technologies and application of video conference systems, a video conference system with higher performance-price is constructed. Embedded technology is taken in this system. By taking full advantage of the power of software technology and virtual instruments, the miniaturization of the Muhipoint Control Unit (MCU) is achieved, and the cost of the system is reduced. Testing results show that the system can support standard H.323 protocol, the latest H.264 video coding standard, H.239 dual stream and a wide range of network protocols. The system has a friendly interface and stable performance, and is with a high practical value.
