Video Conferencing Terminology
A glossary of video conferencing terms and definitions -- the closest thing to being there
December 6, 2005
By: Ben Davidson
Video conferencing has moved out of the corporations and
into countless homes. This glossary provides an invaluable
list of the most essential terms, helping you make sense of
the technical jargon you’re likely to encounter when
choosing your individual video conferencing solution.
Understanding video conferencing terminology arms you
with the necessary knowledge to successfully carry out your search and make the right
consumer choices. As you research video conferencing
products and equipment, you may come across terms you're not
familiar with or want more information about. To help you
better speak the language of video driven communications, we have
provided the most commonly used acronyms, terms and
definitions.
Below you will find a chart with every word
contained in our glossary. To find the term you are
searching for, just click the letter that it begins with.
That will bring up a page with only those glossary terms
that begin with that letter. You will also be provided
a chart similar to that shown below, but with active
hyperlinks to each word contained on that page.
Clicking the word will bring you directly to that term.
