点对点视频会议程序:VideoNet 该程序可以用于两个人在LAN/Intranet(或者Internet)上进行视频会议。现在有许多视频会议程序，每个都有各自的性能提升技术。主要的问题是视频会议视频帧的尺寸对于传输来说太大。因此，性能依赖于对帧的编解码-point-to-point video conferencing : VideoNet the two procedures can be used in LAN/Intranet (or Intern et) on video conferencing. Now there are many video conference proceedings, each have their own performance enhancements. The main problem is video conferencing video frame size too large for transmission. Therefore, the performance depends on the right frame codec

Objective Systems Open H.323 for C (ooh323c) is a simple H.323 protocol stack developed in C. The ASN.1 PER messaging code was developed using the ASN1C compiler using a modified version of our core run-time libraries. Additional open source components as well as code developed in-house were added to produce a functioning stack.

如何成功的运用OPENH323 来开发商业的H.323 协议栈 Openh323 有以下的特征： 1>动态的静音检测算法, 以减小语音包的传输量。 2>支持Windows，Linux 和FreeBSD 的多种客户端命令。 3>包含有MCU，PSTN 网关，和自动语音应答机等多种应用平台。 4>软件支持GSM，LPC-10，G.711 uLaw/Alaw 软件编解码方式。 5>特定硬件（Quicknet/LineXJ）支持G.723.1, G.728 和 G.729 。 6>采用Jitter Buffer 技术对语音信号做接受的缓冲处理。 7>软件产生舒适噪音。 8>采用H.261 视频压缩协议。 9>支持广播的方式查找网守（GateKeeper）。 10>支持H.235 附件D 中和网守的身份认证。(部分地支持H.235) 11>支持部分H.450 补充协议。-How successful the use of OpenH323 to develop commercial H.323
