摘　　要：介绍了流媒体技术的基本原理、网络传输协议及其传播方式,分析了传统智能小区数字音频播放系统中的不足,在原有基础上利用流媒体技术设计和实现了一个功能更为完善的数字音频播放系统。实验表明,该系统在音频服务器和录播终端均为PIII800M的PC机,网络为10Mb带宽LAN条件下完全满足智能小区音频播放要求。Streaming media has become the key technology of audio and video transmission in network for its real-time and interactive features. The basic principles of streaming media technology, the network transmission protocols and the main spread modes of streaming media are introduced. The shortages of the conventional digital audio broadcasting system in intelligent building are pointed out. A more satisfactory digital audio broadcasting system based on streaming media technology is proposed. The experimental results shows that this system completely satisfies the needs of the broadcasting in intelligent building, when the audio-servers and the terminals of recording＆broadcasting are all PⅢ 800M-PCs connected by LAN whose bandwidth is 10Mb.
