摘要
主要研究网络语音传输过成中的关键技术,包括:Voice over IP(VoIP)的原理、网络通信协议H.323和会话初始化协议(SIP)。在此基础上研究并实现一个具有录音、放音、远程传输音频数据的网络音频系统。该网络音频传输系统是在以S3C2410嵌入式处理器为核心的硬件开发平台,RTEMS为软件平台的基础上进行开发,可以通过网络传送声音数据。
Studies the key technologies on network voice transmission, which include VoIP principles, H.323 network communication protocol and SIP. A network audio transmission system which is characterized by recording, implements playback and remote transmission function-alities based on such research results. Designs S3C2410 development board as the hardware platform and selects the RTEMS real-time operating system as the software platform since it is a lightweight, real-time and open source operating system.
