3.14 Dual Stream
(DuoVideoTF/H.239)
Dual Stream is standard on the Utility MXP and Compass MXP. H.239 is the new ITU standard
defining how to send two video sources simultaneously.
With Dual Stream you have the opportunity to receive two different live video streams
simultaneously, main video and one additional source. This is handy when receiving a
presentation. You see the live presentation and the live video of the presenter simultaneously.
When the far end discontinues the Dual Stream the Utilty MXP or Compass MXP will switch over
to single stream.
It is not possible to send a Dual Stream from the Utility MXP or Compass MXP.
Dual Stream and Bandwidth
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. Dual Stream
borrows bandwidth from main video. When Dual Stream is closed, the bandwidth is returned to
the main video.
