C++6.0实现语音采集与播放的控件。souce code 中为该程序的源代码 由于编写该控件的过程中用到了Directx8.1 所以需要安装 Directx8.1sdk 在路径中加入所需的lib exe 中的 ocx 用之前需要用regsvr32 进行注册 如果机器安装的Directx版本低与8.1的话不能运行 该控件没有对语音包压缩 所以对网络环境要求比较高 该控件在校园内经过性能测试-C 6.0 Acquisition and voice broadcast controls. China souce code for the program"s source code because of the preparation of the controls used in the process of Directx8.1 Directx8.1sdk therefore need to install the path to join the lib exe randomly with the use regsvr32 required before registration if machines installed DirectX version 8.1 with low so can not run the Controls no compression of voice packets so the network environment to the high demand on the campus of control after performance testing

ip电话系统设计方案，里面有多个文档，韩盖面广，管理人员可供参考-ip telephone system design, there are a number of documents, covered a wide range Korea, managers for reference

第九章代码，基于ＶＦＷ的视频会议系统-Chapter IX code, based on the VFW video conferencing systems

基于P2P模式的视频通信,比较经典的例子。我看了受益匪浅-P2P-based video communications model, compare the classic example. I have read the benefit

是Opengatekeeper项目的扩展。它支持通过RTP（音频和视频）网守的路由和T.120通讯，因此没有通讯直接在endpoints间进行。-Opengatekeeper project is the expansion. Through its support for RTP (audio and video) Gatekeeper routing and T.120 communications, there is no direct communication between the endpoints.

SIP协议资料。收集与SIP协议相关的资料。是不错的参考资料。-information of sip.

本文主要研究了W-WAN中GPRS网络的移动视频传输问题。文中探讨了GPRS的网络结构、协议体系以及链路特性，从中我们看出： GPRS网络链路不仅具有一般无线链路数据传输中遇到的延迟大、误码率高等共性问题，而且具有移动通信系统采用蜂窝频率复用方式带来的小区切换， 以及由于通信中链路性能随着地理位置变换而变化造成的GPRS网络中不可避免的经常性遭遇的冗长时延和突变时延。 这使得目前GPRS网络中使用的传统TCP或UDP传输协议均不能适应GPRS自身的链路特性，也不能实现高效的分组传输。-This paper mainly studied the W-WAN in the GPRS network for mobile video transmission problems. The article discusses the GPRS network architecture, protocol architecture, as well as link characteristics, from which we can see: GPRS network link not only has the general wireless link data transmission delay encountered in large, common problems of higher bit error rate, and with mobile communications system uses a cellular frequency reuse methods brought about by cell switching, as well as the communication link performance with the location change and change is inevitable GPRS network, the recurrent encountered lengthy delay and delay mutation. This makes the current GPRS network using the traditional TCP or UDP transport protocol are una

版本V4.1.1,Linux上的开放源代码的IP电话软件SIP协议，主要用于语音通话，但它也支持发送文本的即时消息，即可以像ICQ那样地用文字聊天。 如果网络带宽足够的话，它还支持可视电话 Kphone是GPL的开放源代码的软件。-version 4.1.1, It is IP phone software of Linux open source code based on SIP protocol, it can be used to voice communication, and surpport text IM, same function as ICQ used to text chat. In broad band circumstance, it surpport video conference. Kphone is GPL open source software .
