文件名称:可视电话软件
介绍说明--下载内容均来自于网络,请自行研究使用
NetTalk是一个适用于局域网和因特网的可视电话软件
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,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J)
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。-NetTalk is applied to a LAN and the Internet a video phone software. Windows 2000 Server Development Environment
