Frequently Asked Questions
What is videoconferencing?
Videoconferencing allows two or more people at different locations to
see and hear each other at the same time. In addition, it is often possible
to sharine computer applications such as Internet pages, library catalogs,
or software. This rich communications technology offers new possibilities
for schools, colleges, and libraries including formal instruction (courses,
lessons, and tutoring), connection with guest speakers and experts, multi-school
project collaboration, professional activities such as meetings and interviews,
and community events.
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.
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).
OHSU uses a product from Polycom as the codec.
equipment will I need to conduct a videoconference?
Equipment requirements include a codec (Polycom unit), camera, speaker,
microphone, compression software, and telecommunication network.
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
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; tapping by the microphone is
distracting, dark suits or plaids do not transmit very well in video,
and large print works best for overhead camera material.
