The different video sources need different Video Quality Settings. Main Camera, VCR, AUX and
Split Screen have Motion as default. PC, Document Camera and VNC have Sharpness as
default.

Motion*

Optimized for smooth motion video (CIF/SIF or w288p for low bandwidths,
448p/400p, Interlaced CIF (iCIF) / Interlaced SIF (iSIF) or w448p for high
bandwidths).

Sharpness*

Optimized for sharp video (4CIF/4SIF, SVGA, XGA, w720p).

Auto

The system chooses the best of Motion or Sharpness depending on picture
layout and bandwidth.

5.4.6.1 Intelligent Video Management (IVM)

It is possible to configure the picture sent from the system depending upon specific requirements
and applications adding an additional level of flexibility and adaptability.

Generally, the IVM will always try to transmit the format closest to the video input format. Each
video input can be configured to either motion or sharpness:


Motion*:

When there is a need for higher frame rates, typically when a large number of participants are
present or when there is a lot of motion in the picture.

At low bit rate:

ƒ CIF will be used from a PAL video input
ƒ SIF from NTSC
ƒ w288p from wide format (HD720p) input
ƒ VGA/SVGA/XGA from PC, Digital Clarity


At high bit rate:

ƒ 448p will be used from a PAL video input if Natural Video is ‘Off’ or ‘Auto’ or if

Natural Video is ‘x kbps’ and the bit rate is lower than x kbps

ƒ 400p from NTSC if Natural Video is ‘Off’ or ‘Auto’ or if Natural Video is ‘x kbps’ and

the bit rate is lower than x kbps

ƒ iCIF will be used from a PAL video input, if Natural Video is ‘x kbps’ and the bit

rate is higher than or equal to x kbps

ƒ iSIF from NTSC, if Natural Video is ‘x kbps’ and the bit rate is higher than or equal

to x kbps

ƒ w448p will be used from a wide format (HD720p) input
