What is videoconferencing_
Videoconferencing is the transmission of images (video) and speech
(audio) back and forth between two or more physically separate locations.
How can
I find a videoconferencing system at my remote office/client's_
An international standard (H.320) has been adopted worldwide and
pubic access rooms can be found worldwide. Many public rooms can
be found through Internet directories.
How good
is the picture quality with videoconferencing_
You can think of picture quality in terms of "good", "better", and
"best". The more bandwidth that is allocated the better the picture.
If your application features a platform trainer or a lot of movement
is involved then you'll need to plan for the "best" or 384kbps.
If you're using ISDN, 384kbps is 3 ISDN lines, the more bandwidth
you use the more expensive the call.
How does
videoconferencing work_
Videoconferencing systems compress video and audio signals so they
can be transmitted over existing telecommunications networks. The
engine that compresses the video and audio signal is called a codec
(coder/decoder).
What
equipment will I need to conduct a videoconference_
Equipment requirements include a codec, camera, speaker, microphone,
compression software, and telecommunication network. Most local
telephone carriers offer digital networks capable of supporting
videoconferencing.
Can I
have a videoconference with more than one site_
Yes. In addition to point-to-point videoconferences, you can have
a multi-point videoconference among multiple sites using a video
"bridge". Video bridges are available for sale by videoconferencing
vendors and some network carriers offer this capability on a case
by case basis with their service.
How easy
is videoconferencing to use_
Keep in mind that videoconferencing is like interactive television.
Your friends/colleagues can see and hear you as well as you can
see and hear them. Here are some tips to keep in mind; loud laughing,
clapping, or tapping by the microphone is distracting, dark suits
or plaids do not transmit very well in video.
