IVM Resolution
The below table shows the relationship between Transmission modes selected by
the system when Motion or Sharpness is set in the Call Quality menu. IVM will use
this table to optimize the Video quality, according to the capabilities of the remote
system(s):
Basic Video Quality Video Input Transmission Mode Selection Rules*
MOTION PAL 448p -> iCIF@50 -> CIF -> QCIF
MOTION NTSC 400p -> 448p -> iSIF@60 -> iCIF@60 -> SIF -> CIF -> QCIF
MOTION VGA 448p -> CIF -> QCIF
MOTION SVGA 448p -> CIF -> QCIF
MOTION XGA 448p -> CIF -> QCIF
MOTION Wide w448p -> w288p -> CIF -> QCIF
SHARPNESS PAL 4CIF -> VGA -> CIF -> QCIF
SHARPNESS NTSC 4SIF -> 4CIF -> VGA -> SIF -> CIF -> QCIF
SHARPNESS VGA VGA -> 4CIF -> CIF -> QCIF
SHARPNESS SVGA SVGA -> XGA -> 4CIF -> VGA -> CIF -> QCIF

SHARPNESS Wide w720p -> w576p -> w448p -> w288p -> CIF -> QCIF
Intelligent Video Management (IVM)
You may configure the picture sent from your TANDBERG sys-
tem depending upon specific requirements and applications
adding an additional level of flexibility and adaptability.
Generally, the IVM will always try to transmit the format clos-
est to the video input format. Each video input can be config-
ured 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:
CIF will be used from a PAL video input
SIF from NTSC
w288p from wide format (HD720p) input
VGA/SVGA/XGA from PC, Digital Clarity.
At high bit rate:
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
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
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
iSIF from NTSC, if Natural Video is x kbps and the bit rate is
higher than or equal to x kbps
w448p will be used from a wide format (HD720p) input
VGA/SVGA/XGA from PC, Digital Clarity.
Sharpness*:
Improved quality of detailed images and graphics, lower frame
rate, ideal for enhancing quality at lower bandwidths.
4CIF will be used from a PAL video input, Digital Clarity
4SIF from NTSC, Digital Clarity
w720p will be used from a wide format (HD720p) input
VGA/SVGA/XGA from PC, Digital Clarity.
