					What Is Video Conferencing

When you call for a conference, everyone is expected to arrive at a
designed time and place to discuss an issue and resolve it. But if the
people you need to speak with are in different states or countries and
those cost of getting them to come is quite expensive, you have to try
something else like video conferencing.

But first, what is video conferencing? Basically, this is a system that
allows you to conduct meetings or trainings in different places
simultaneously. It incorporates audio, video so you are able to talk and
send data which takes away the barrier of distance that separates these
individuals.

To make video conferencing possible, you need to buy the equipment. You
also have to choose the method of transmission because the one you might
be using may not be compatible with the other person.

These include the Codec unit, the camera, microphone, video display,
network connection, stands and equipment charts if these will be mobile
or stationary, NT-1 and chicken feet.

Most of these are self-explanatory so we will just focus on the Codec,
NT-1 and chicken feet.

The Codec is considered to be the “brain and heart” of the video
conference system. This is what compresses everything so you can send and
receive messages on real time which can be viewed on the display device.

The NT-1 on the other hand is an electronic device otherwise called an
terminal adapter that converts ISDN to your IP format. There is also the
NT-3 version so instead of using one line, you will be able to use three.

The chicken feet also known as acoustic echo cancellers are equipment
that is usually hung from the ceiling. Basically, what this does it’s add
both clarity and depth to the resonant frequency response of your audio
sub system.

But the most important which you have to understand is the network
connection. There are two protocols namely the H.320 and the H.323. If
the one you are talking with is using a different one, it will be
impossible for you to talk with one another because while the first uses
ISDN lines the latter which is much simpler uses IP lines similar to what
you use to browse the web.

The good news is that you can still talk to the person on the other end
using the older system by using a bridge that is able to handle these
mixed protocols.

The advantage of the new system is that you can transmit for multiple
uses when the old one can only handle one. The newer version is also
cheaper and faster so you get to talk in real time.
How much will you have to spend to get   your video conferencing system up
and running? Personal users will spend   less than $500 while corporations
could spend $100,000 or even more. You   just have to shop around and see
which one is able to fit your needs so   you get value for your money.

The video conferencing system of today is one of the highlights of living
in the digital age. No longer do we have to send a message and wait for
awhile to get a response when you can get a reply right then and there
which increases productivity and saves time and resources.
