Dual Video Stream

Sharing information using two video streams
V
ideo systems equipped with the
optional dual video stream provides
the opportunity to show two different
live video streams simultaneously, main
video and one additional source. This
is handy when showing a presentation.
You will then let the others see the live
presentation along with the live video of
the presenter—simultaneously.
When you start a presentation, the
second 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.
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—they will see the
presentation, but nothing else.

No dual video stream?

The dual video stream ability is an
optional feature, but available as retrofit.
Contact your system administrator or
your TANDBERG representative for
details.

Dual stream and bandwidth

When using dual stream, the quality
automatically downspeeds to the
optimal bandwidth. This means that you
need higher quality to allocate enough

bandwidth for the two video streams.
The second stream borrows bandwidth
from the main video stream. When
second 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 an MCU conference as
MultiSite host or when connected to an
external MCU.
Your administrator may specify the
amount of bandwidth allocated to
presentations. If you frequently run
video presentations, you may want to
have a higher bandwidth than if you
stick to static Powerpoint presentations.
This setting can be adjusted in
the Control Panel by your system
administrator. Note that this setting may
be password protected.
