Dual Video Stream
Video 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
meeting, dual stream will be
established if at least two systems support
it. Those not supporting it will get no
second stream! They will, however, 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
adminstrator 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.
