Video Conferencing Basics

This article will provide you a brief introduction about what actually video conferencing is. By video conferecing we can connect with some other identity and also can see the video online in real time. It is now useful and very interesting technology and widly used worldwide.

What is Video Conferencing: Video conferencing is the integration of video, audio and peripherals to enable two or more people to communicate simultaneously over some type of telecommunications lines. By video conferencing you are transmitting synchronized images and verbal communications between two or more locations in lieu of them being in the same room.

Video conferencing ingredients: The main ingredients of successful video conferencing are video cameras, microphones, appropriate computer software and computer equipment and peripherals that will integrate with the transmission lines to relay the information.

How video conferencing works: The analog information recorded by the microphones and cameras is broken down into discreet units, translating it to ones and zeros. A Codec encodes the information to a digital signal that can then be transmitted to a codec at the other end, which will retranslate these digital signals back into analog video images and audio sounds.

In the earlier days, video conferencing was very much expensive than today. Some time back video conferencing was used by T1, ATM and ISDN lines. These all process were very costly for video conferencing. Since internet is very cheap and it is a very good medium for video conferencing. The TCP/IP connections of the Internet are much less expensive and can carry large quantities of information for video conferencing, including video packets for conferencing, relatively easily. Because of this, video conferencing has become much more prevalent in small businesses and in desktop packages that can be set up with software for computer-to-computer networking.

The problem faced was in video conferencing was that when we convert analog to digital for transmission then it is the loss in clarity of image. The most important factor in video conferencing is the compression ratio. The higher the compression ratio, the more quickly the information is capable of being transmitted. In many cases, however, this also means some loss in clarity or audio/video quality.

Advantages of video conferencing: Using video conferencing you can communicate with whole groups of people at once either through networking a group of computers or by form of broadcast. This is a huge step forward for both companies and for schools. video conferencing is very useful for students in their studies. Students can enjoy learning this way much more than from a textbook. Informed people can talk to classes and help them learn, where otherwise they wouldn't be able to because of time and distance restrictions. This is also a bonus for children who have different learning styles. The more visual types who understand better when they can see what they're working with.
