Continuous Presence is a visual set-up where all sites are visible on the screen
at the same time. In other words, the effect is much like "Hollywood Squares."
This set up works only when there are a few sites (lets say 5 or less) on a call
and must be requested when scheduling your event.
Lecture Mode allows the site that is presenting to view the other sites in a
rotating cycle during the videoconference. The participating sites will be
displayed on the Lecturer's screen for a predetermined duration. All of the other
sites see the lecturer's site on their screen. This also must be requested when
scheduling your event.
Webcasting
Webcasting refers to the process where an educational videoconference session
is broadcast over the web (Internet) at the same time. There are two kinds of
webcasts:
Live Webcasts: For videoconferences with live webcasting, the presenter delivers
the session from a videoconference location but where the session can be
viewed either by videoconference or through the web. Participants viewing
through the web only need to log onto a computer with Internet access. This
session is time dependent, as participants must "tune into" the web at a specific
time.
Archived Webcasts: This means that the session has been "taped" and is
available for viewing at a later time. It is stored on the servers at OTN, and can
be accessed through the Webcasting link on the OTN website.
