| 摘 要： | 文章提出的远程协同鉴定系统是基于H.323协议栈开发的一个可适用于多种领域的实时远程鉴定交互系统。通过提供音视频混合、文字交流等技术，在低带宽的条件下实现了传送高清图像，服务于远程专家及一线工作人员，能方便高效地对未知标本进行鉴别，增加了鉴定工作的准确性和权威性。同时，针对H.323标准的视频会议统和IP电话在实际应用中存在的NAT与防火墙的穿透问题，文章提出了一种解决方案，该方案无需对现有的防火墙系统做任何改动。

| Abstract: | The remote collaborative identification system is based on H.323 protocol. It is a real-time interactive system can be applied to various fields. By providing mixed audio, switching video, written communication technologies and so on, what’s more, transport high-definition image under low bandwidth conditions between remote experts and the work staff, this system can conveniently and efficiently identify the unknown samples, increase the accuracy and authority of the identification work. At the same time, this paper gives a subtle solution for the very knotty problem：NAT and the firewall penetration, exists in H.323 conference system and IP telephone in practical usage. And the solution does not need to change the existing firewall system. |
