					The Use of Video Conferencing

A videoconference is a kind interaction through devices, which allow two
or more people in different places to remotely communicate
simultaneously. It is also called video meeting or audio-video remote
meeting. It’s different from a videophone because the technology is
focused on the conference not the individual.

 The most primitive type of video conferencing equipment is the
television. Though the transmission of information was one way there is
feedback after transmission. The cycle of information and the process of
feedback is fulfilled by the television that qualifies it as a video
conferencing equipment.

Since the development of digital telephony and internet based services
like software, such as NetMeeting, MSN Messenger, Yahoo Messenger and
other instant messaging web plug ins that allow transmission of messages
real time through the internet. The Internet has become the most
important tool for video conferencing and other instant messaging
services.

Because of the sheer speed that the Internet has within it self and the
ability to transfer information real time most of the web based
videoconference centers puts most of its resources online.

Because of the advancement of Internet technology it has been possible
over the years to have simultaneous videoconferencing among three or more
remote points. These remote points can be anywhere in the world and the
remote locations need not have a special set of equipment or software.

There is a bridge though that connects all of these remote peripherals on
to the network and that is called the MCU or the Multi Channel Unit, it
allows different computers to run the same format code to et communicate
in one network.

There are MCU bridges for   IP and ISDN-based videoconferencing. The MCUs
used as bridges on IP and   ISDN connections are most of the time pure
software, and others that   can be found in other forms of connections are
a combination of hardware   and software.

An MCU’s type is determined according to the number of simultaneous calls
and conference participants it can handle, its ability to carry out
information exchanges, shared programs, shared documents, shared
application and other different kinds of sharing peripherals available on
the conference. One god thing about MCU’s is that it can be a complete
stand alone software for conferencing since it does not need hardware
acceleration because it is purely software accelerated.

Because of the needs and the technology available to meet those needs,
video conferencing has been more than a necessity for education,
medicine, law making, and business.

For education the impact of video conferencing to it and the system can
be seen easily. Because high speed Internet connection is becoming a
much-needed part of modern curriculum, video conferencing has also been
part of the next step towards modernization of the school system. Because
of video conferencing special lecturers can now remotely conduct
lectures, teachers can be on location and still deliver the lesson and
correspondence between schools can be easily done through video
conferencing.

Videoconferencing classes also adds to the possibility of a conversation
in the scenarios such as a live conversation is needed between people in
different countries. A visual information is an important component of
the telephone conversation, the parties of the conversation can't
physically come to the same location.

The expense or time of travel is a consideration because these situations
calls for something drastically fast and efficient.
