Using Multipoint
In a point-to-point videoconference, thereÕs only one way to participate: you see
the other site, and the other site sees you. In a multipoint videoconference, there
are at least three sites, and there can be many more than that.
ThereÕs a lot more to think about in a multipoint call Ñ which site does the
speaker view? which site do all the other sites view? who controls the conference?
and so on. The various multipoint modes Ñ voice-activated, browse, chair
control, and director Ñ address these issues.
You wonÕt be able to use every multipoint mode. The type of keypad you have
and the bridge you connect to determine which modes you can use. If youÕre
using the QuickPad, you can only use voice-activated mode. If youÕre using the
wireless keypad, you can use browse mode and either chair control or director
mode Ñ whichever is listed on your Browse menu.
Using Voice-Activated Mode
Voice-activated mode is the simplest way to take part in a multipoint
videoconference. ItÕs also the only multipoint mode available to everyone.
In voice-activated mode, everyone sees the person whoÕs currently speaking. The
current speaker sees the person who spoke last.
In this mode, you donÕt need to press any buttons Ñ your Concorde • 4500
automatically switches to the appropriate site and displays the person whoÕs
currently speaking. If youÕre the one whoÕs speaking, your system displays the
site of the previous speaker.
Use voice-activated mode on your Þrst multipoint call. Once youÕre comfortable
with it, you might want to try the advanced modes. These allow you to take more
control of a meeting. For example, you can choose the site you view, or even select
the site everyone views.
