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.
