Duo Video/H.9:
Duo Video/H.239 may be sent in both CP and Voice Switched mode.
The TANDBERG MPS will transmit the same format as the one received if all the sites are capable of receiving it. The
Video Format will fallback as described above (for Voice Switched mode).
8... H.+ Custom Video Formats (Digital Clarity
TANDBERG MPS supports encoding of a true XGA, SVGA, VGA and NTSC (SIF) resolutions. This allows the
TANDBERG MPS to send all video signals in their true 'native resolution'. If the source is sending XGA, SVGA or
VGA, the receiving system will decode and display the same quality image as was sent by the transmitting side. Also
supported under the H.263+ custom formats is TANDBERG's use of SIF (Source Input Format) that allows for an
improved NTSC image over traditional CIF based MCU.
8... CIF Digital Clarity
This feature allows for H.263 4CIF (704x576) live video images to be sent to the far end allowing 4 times higher
resolution than traditional videoconferencing systems for displaying document camera video and other high-resolution
images.
8... H.+ Widescreen formats
TANDBERG MPS support encoding of true widescreen (16:9) formats: w288p (512x288) and w576p (1024x576).
Widescreen formats will only be used if all participants in the conference support it. When encoding widescreen
formats, the TANDBERG MPS will use special
layouts designed to utilize widescreen monitors. Refer to Video – Conference Layout for a list of all available layouts.

system and to be received by the other participants. This feature is supported on both H.320 and H.323. This allows a
presenter and their presentation to be seen at the same time, in much the same way you would expect them to be in a
local room environment.
If systems in a conference are TANDBERG dual monitor systems, they will receive the presenter on one screen and
the presentation (PC, Doc Cam, VCR, DVD etc) on the other. If the TANDBERG system is a single monitor system
with default settings, the video stream will automatically switch from the presenter to the presentation. This change
will take place on the fly with the displayed stream returning to that of the presenter when H.239/Duo Video
disconnected.
In the TANDBERG MPS there is support for mix of H.239 and Duo Video
manufacturer's systems supporting neither H.239 nor Duo Video

The TANDBERG MPS is capable of receiving/transmitting two simultaneous video signals from/to all sites. When
