摘要
组播技术可以大大提高网络的传输效率,节省网络带宽。在局域网上实现声音的实时捕捉和组播传送具有较大的实际意义。本文对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VisualC++6.0环境中实现局域网音频的实时捕捉和组播传送的关键技术和方法。
Multicast can improve the transport efficiency and save the bandwidth of a computer network.Practically,it is important that the sound is captured in real-time and transported by multicast in a LAN.This paper studies IP multicast technology,WinSock control component programming theory and DirectSound firstly.Then it discusses implementation of real-time capture of sound and the design method of multicast in Visual C++6.0.
