摘　　要：多点传送即组播技术可以大大提高网络的传输效率,节省网络带宽。一些实际应用要求在局域网上实现声音的 实时捕捉、组播传送和播放。对IP组播技术、WinSock控件编程原理以及DirectSound对象进行了研究,探讨了在Visual C+ +6.0环境中实现局域网音频的实时捕捉、组播传送和播放的关键技术和方法,并给出了一个成功的应用。Multicast can improve the transport efficiency and save the bandwidth of a computer network . Some practical applications acquire that the sound is captured in real-time, transported by multicast and played back in a LAN. IP multicast technology, winsock control component programming theory and directsound are studied. Then it discusses the implementation of real-time capture of sound, design method of multicast and playback of sound in visual C++6.0 through a successful application is discussed.
