Communication continues to make this world a smaller place. The current era of connecting people seems to be light-years away from the days of traditional paper-postage. The Internet may have had sparked a revolution a few decades back, but innovations keep pouring in. Such an innovation is the video conferencing system. It is a process by which two or more people from varied points in the world (or even outside!) can communicate via video and audio transmissions.
In more simple words, any number of people can interact with each other without having to physically close. It is almost the same as talking face-to-face; only, all the members needn’t be in one place! Deals can be fixed, urgent conferences may be held, as well as important files may be passed immediately, ensuring it catches the recipient’s attention. But get this clear, video conferencing is different from video-telephoning.
How Video Conferencing Works?
Video Conferencing also known as Video Collaboration uses audio and video telecommunications to bring people at different sites together. It basically requires internet connections on sides, camcorders and effective audio systems . Such conferencing enables a conversation between people in private offices (point-to-point) or involve several (multipoint) sites in large rooms at multiple locations. There are several companies in India developing video conferencing systems.
These systems can be used in a host of different scenarios, resulting in the current world becoming an era of video conferencing systems. General uses for video conferencing include business meetings, educational training or instruction and collaboration among health officials or other representatives. The most evident industries that use video conferencing are some of the following:
- Distance Learning
- Modern Homes
- Legal Services
Video Conferencing Technology
The world has gone digital and so has communication. Video conferencing takes sharing of data and updates to the real-time arena, with digital compression of video as well as audio streams. This compression is performed by video collaboration software known as a codec The data compressed by a codec is usually transmitted through an ISDN or IP digital network.
The other main components of a video conferencing system are:
- Video camera or webcam
- A video output device such as a computer monitor, television or projector.
- Microphones or any kind of Preamp audio outlet to transmit audio.
- A LAN or Internet connection for the transfer of data
- A computer or laptop
The world has become fast giving stress to the old proverb which goes “Time and tide waits for no man”. Similarly, time is precious in the world of commerce where a single hour lost, can make or break a conglomerate. Video conferencing systems and software serve this purpose exactly. Distances no longer present a challenge to growing businesses. One can share a video conference with an entrepreneur in the other part of world, with different government departments as well as the staff of his or her company; with just a single click!
