TANDBERG 1700 MXP USER GUIDE

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.

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	XGA	XGA -> SVGA -> 4CIF -> VGA -> CIF -> QCIF
SHARPNESS	Wide	w720p -> w576p -> w448p -> w288p -> CIF -> QCIF
