Description: NetTalk是一个适用于局域网和因特网的可视软件
一． 开发环境
Windows2000 Server & Visual C++6.0 & SDK
+自开发的CWndX类库(相当于简化的MFC涉及窗口的部分)
二． 支持环境
Windows98/ME/2000/XP
三． 所涉及协议和标准
网络传输采用UDP协议（被封装成支持超时重传等机制的UDP类），音频压缩采用G.729标准，视频压缩采用H.263标准
四． 性能参数
以音频帧为基准，每帧音频数据有２４０个采样点，时间为２４０＊１０００／８０００＝３０ms，８０００为音频的采样率。
数据接收端队列缓冲延迟：３０＊3＝90ms
数据发送端录音延迟：30ms
数据压缩解压耗时：<40ms
网络延迟：<100ms（我想校网情况应该不错 ）
总延迟：<260ms
根据VOIP标准，总延迟<300ms是人可以接受的，以上计算是保守的，实际情况可能会好得多。
带宽需求
数据类型 带宽需求（byte/sec） 带宽总需求（Kbyte/sec）
音频 1000*2 ~8.98*2
视频 ~8000*2
帧头 ~200*2
