Video input configured to Sharpness
Sharpness* gives improved quality of detailed images and graphics and lower
frame rate. Sharpness is ideal for enhancing quality at lower bandwidths.
•
4CIF will be used from a PAL video input, Digital Clarity

The table below shows the relationship between the video input and the
Transmission modes selected by the system when either Motion or Sharpness
is selected in the Call Quality menu. IVM will work in accordance with this
table to optimize the Video quality, according to the capabilities of the remote
system(s):

Intelligent Video Management (IVM)
You may configure the picture sent from your Cisco system to reflect
your specific requirements and the applications being used adding an
additional level of flexibility and adaptability to your system.
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:
Video input configured to Motion
Motion* is used 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 will be used from a NTSC video input
•
w288p from wide format (HD720p) input
•
VGA/SVGA/XGA from PC, Digital Clarity
•
WXGA /1280x768), 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 will be used from a NTSC 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
•
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 will be used from a NTSC video input, if Natural Video is
x kbps
and the bit rate is higher than or equal to
x kbps
•
w720p or w448p will be used from a wide format (HD720p) input
•
