Has anyone thought on how Video conferencing came about to be what it is in the present time? Video conference started on the idea based upon the Television transmission. This is usually a one way output for the observer and no input from the viewers.

Then came the Video Teleconferencing technique which is based upon input and output from the users. The input and output is the sending and receiving of audio and video signals. The equipments used at the start of this method were: video cameras and screens; microphones with input and output facilities; speakers; and special transmission equipment for receiving and sending out signals at the location for the conference to take place.

When a conference would hold, all the members taking part would have to be present as a group in a room at the same time at each location. The signals sent and received were slow with low video conferencing definition.

This soon led to the introduction of wireless communication. The technology used for a Video Conferencing has now expanded gradually over time to make this a cost effective mode of communication.

With the introduction of the Internet, some companies are now offering ISDN and IP to make transmission fast and with high video conferencing definition. Without special equipments needed for conferencing, communication can not be carried out. So it is also necessary to find those companies that offer these special equipments. Video conferencing can now be carried out at one's desktop with the introduction of the latest technology.

One has to wonder, how much further technology can go; it seems endless.
