What Is Video Conferencing?

Video conferencing isn't necessarily a new technology, but it has come a long way since it was first introduced and for the most part makes good use of the new technologies that have been introduced in recent years. By allowing people to communicate either with video and audio or video and text, video conferencing serves a number of purposes in business, as well as for personal use and even use by groups as diverse as the court system and NASA.

In order to understand how video conferencing works, however, it's important to take a moment to learn how the technology first came about and how it has been adapted over time to meet the needs of businesses and consumers.

Origins of Video Conferencing

Early forms of video conferencing originated with the advent of television, using a pair of closed-circuit televisions which were connected by cable to allow the users at either end to communicate. Later advances on this theme were used by news reporters on location, who transmitted a signal back to the station from a truck filled with equipment, and also by NASA who used high-powered radio waves to transmit signals to and from space missions. Attempts were made by AT&T and other companies during the 60's and 70's to make video conferencing more accessible, but poor picture quality plagued these early systems and even when more powerful devices were made they still did not become popular.

Modern Video Conferencing

In the 80's, new technologies such as ISDN networks made it possible to guarantee a minimum transfer rate and compression rate for video and audio which in turn made video conferencing much more feasible. Dedicated networks for video conferencing began to develop, and ISDN was soon accessible from most parts of the world. Video conferencing was originally prohibitively expensive for most, but as new advances in technology continued to be created the prices of video conferencing equipment soon dropped and it became much more common.

The advent of the internet did much to bring video conferencing where it is today; once the technology was developed to transmit live video and audio over internet protocols, much of the equipment previously needed to create video conferencing connections was no longer required. Many free programs and services soon began to include webcam video conferencing in their chat features, allowing computer users to communicate as never before.

Uses of Video Conferencing

Video conferencing has a number of uses, both at home and in business. When using a webcam or other form of video conferencing from home, you can use it to stay in touch with friends and family across the city or around the world. It can add a bit more of a "human touch" to conversations or chat sessions, as you can actually see the person that you're talking to instead of them simply being words on a screen or a voice on the phone. In business, the applications are even more useful; business meetings can occur among several different offices or individuals in different parts of the world. Not only can this add a great deal of convenience, but it can also save money that would have to be spent on transportation and time that would have to be spent on organizing the meetings and getting all of the parties in the same place at the same time. Video conferencing can also be of great use to educators, science professionals, and a variety of other individuals who can see the advantage of being able to speak face-to-face with others without the need for actually meeting each other in a specific location.
