| Abstract: | 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. |
