Video conferencing is considered a marvel of technology, but often it’s the internal programs that really are the stars. Many concepts would never come to life without the help of the internal systems that make the programs work. Most users don’t care how the system works as long as it does. If you can better understand how video conferencing works, you can customize a system that works best for you.
The H323 system is one of these tireless workers. If H323 were a member of a castle, he would be the messenger between the gatekeeper and the king. H323 was originally designed to provide video conferencing capabilities over a local area network. Its first purpose was to send messages through an IP system. Modifications and customization have made the H323 a superior tool for successful video conferencing.
When a user initiates a call, the gateway takes care of opening the connection. Endpoints are responsible for notifying the system of activity. The H323 ensures that the message is expedited quickly between the two.

H323 video conferencing has gained respect and credibility since the day it was released. It can be used for both point-to-point and multipoint conferences. It’s fast, efficient and gets the job done.
As capable as it is, the H323 doesn’t work alone. There are several protocols that share space and functions in the system. RAS is used for resolution and admittance control. RTP is there to optimize the sending and receiving of text and audio data between participants.
Terminals are also vital members of the H323 team. They are basically terminals and the simplest part of the whole system. They are also called protocol stack. They have the ability to support all video data coming through the system. They are the workhorses of the system and use all the possibilities of the system.
Codecs also play a role in the H323. They are responsible for video encoding and decoding throughout the system. The G711 allows terminals to encode and decode audio data.
The resurgence of the H323
There was a time when ISDN VTC and H320 were the standard systems for operating video conferences. The military, government, and corporations still use this system because of its ability to get the job done. They lost popularity among the general public as other video conferencing options came onto the market that were more modern and easier to use.
There is an increase in interest in these systems again due to the increasing cost of Internet services. H323 can be used by any high-speed Internet connection out there, so it’s not difficult to access. The ISDN system may cost less than its competition.
It’s easy to take for granted the technology that makes video conferencing possible. The ability for it to work depends on many systems working together in harmony. Understanding what each part does will help maximize the efficiency and use of the entire system.
