网络多媒体通信

1、编制一个网络多媒通信软件，实现：

在发送端采集话筒声音，通过网络实时传输到接收端，并在接收端播放出来。

2、通过使用TCP、UDP、变更分组大小来对比收发端声音同步情况及播放质量。

本实验技术不同于课上所讲的回调函数，利用了MFC的消息处理机制，用消息处理函数替代了回调函数，但整个流程是一样的。本程序采用C/S模式，其中Server端为项目PhoneToFile，Client端为项目Client，Server端的功能为采集声音数据并发送给客户端，Client端将收到的声音数据播放。在测试中只需在Server端打开Server程序并播放音乐或用话筒录音，在Cliet端打开Client程序，用耳机就可以听到音乐或录音。-Internet Multimedia Communications

1, the preparation of a network of multi-media communications software to achieve:

　 In the transmitter microphone capture sound, real-time transmission through the network to the receiving side, and playing out at the receiving end.

2, using TCP, UDP, change the packet size to compare the situation and simultaneously send and receive-side audio playback quality.

The experimental technique is different from the class talked about the callback function, use of MFC s message handling mechanism is replaced by the message handler callback function, but the whole process is the same. This program uses C/S mode, in which Server-side for the project PhoneToFile, Client-side for the project Client, Server-side functionality for the capture audio data and sent to the client, Client-side will receive the voice data playback. In the test, simply open the Server in the Server-side program and play music or microphone recording, open the Client program
