Video Conferencing

In video conferencing, synchronized images and verbal communication are transmitted between two or more locations. Now that we have videoconferencing defined, how does videoconferencing work?

Why Video Conferencing Works For Many

For video conferencing to work, you would need microphones, video cameras, the necessary computer software, hardware and peripherals, along with the transmission lines for sending video conferencing information amongst video conferencing participants.

When holding a video conferencing event, a codec translates the analog information received by the microphones and video cameras into digital information, which is then transmitted to another codec that translates the digital information back to the original sounds and images, which the video conferencing participants can understand.

Video conferencing used to be more expensive than it is today, because T1, ATM and ISDN lines were used for video conferencing, and all of these were very costly. However, the emergence of the Internet has provided a cheaper solution for video conferencing, using web video conferencing. As a result, video conferencing has become more present in small businesses.

The problem with video conferencing is that the conversion of information from analog to digital format can result in the decreased video quality. The compression ratio is the most important factor in video conferencing. The higher the compression ratio, the faster the video conferencing information is transmitted, but the lower the video quality.

Video conferencing can be used for communication among groups of people. Video conferencing is also very useful in education. Video conferencing can make learning more fun, and video conferencing can work for different learning styles. Video conferencing also allows experts from remote places to talk in classes.

Video conferencing is the wave of the future. Make video conferencing work for you, know more about video conferencing, and make a step forward on improving your conferencing services.
