Video Meeting Features
About Dual Video Stream
With Dual Stream (optional) you have the
opportunity to show two different live
video streams simultaneously, main video
and one additional source. This is handy
when showing a presentation. You see
the live presentation and the live video of
the presenter simultaneously. When you
start a presentation, Dual Stream starts
automatically if both local and remote
system supports Dual Stream. If one of the
systems does not support Dual Stream, no
second video stream will be established
and your presentation will be shown as your
main video instead. However, in a MultiSite
meeting dual stream will be established if
at least two systems support it. Those not
supporting it will get no second stream!
Dual Stream and Bandwidth
Using Dual Stream, the quality automati-
cally downspeeds to the optimal bandwidth.
This means that you need higher quality
to allocate enough bandwidth for the two
video streams. Dual Stream borrows band-
width from main video stream. When Dual
Stream is closed, the bandwidth is returned
to the main video.
Note that when selecting the Document
Camera or PC, the system will automatically
request floor when connected to a MCU
conference as MultiSite host or connected
to an external MCU.
The Presentation menu will now be
displayed.
Make sure the DuoVideo tab is
selected (as shown here) and
navigate to the source whose
contents is to be sent as dual
stream.
You are free to choose whether the dual
stream (the other stream) shall be your
camera or your presentation – see the
previous page for more on this.
