摘　　要：设计一种基于H.323协议的嵌入式音频传输系统。该系统利用海思HI3531A多媒体处理芯片对输入的音频信号进行相关的编码,再通过实时流媒体传输控制协议RTP/PTCP进行封装后在网络传输,在接收终端进行音频解封装和解码。测试结果表明该系统能高效稳定工作,可用于对音频传输要求高的社区安保系统、施工现场指挥系统等应用场合。Designs an embedded audio transmission system based on H.323 protocol.The system uses the HiSili HI3531A multimedia processing chip to encode the input audio signal,and then encapsulates it in the network through the real-time streaming media transmission control protocol RTP/PTCP,and performs audio decapsulation and decoding at the receiving terminal.The test results show that the system can work efficiently and stably,and can be used in applications such as community security systems and construction site command systems that require high audio transmission.
