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.
