TELECOMMUNICATION

A group of people enter a room, the lights go down, the screens come... the videoconference is under way.

Tomorrow's scientific fiction has become today's new technology - daily reality for global companies who recognize the importance of regular communication between groups of people in different locations round the world.

Essentially the videoconference room resembles a usual conference com. Delegates sit along one side of a table facing their colleagues on screen on the other side. They can see, hear and talk to each other simultaneously and can present slides of diagrams, even pieces f equipment. The technology is relatively simple. A device called video codec takes the picture, digitalizes it for transmission over a special network and reforms the picture at the other end.

The problem today is to manufacture codec to the new international standard and to improve picture quality through faster transmission needs. Research and development is also focusing on mobile videoconferencing with broad cast quality pictures which enable to have instant communication with colleagues around the world.

There is no doubt about the effectiveness of videoconferencing, as tie videoconference eliminates the working time lost through travel.
