5.2.2 Chroma Level
Chroma level adjustment is accomplished the same way as the luma level
described above––you select Chroma from the menu after which the same rules
that governed Luma adjustments apply to Chroma adjustments.
Steps, maximum and minimum levels are also the same.
5.2.3 Set Up Level
Set up level adjustment is very similar to Luma and Chroma levels but with a few
differences.
First, the value shown is relative, not the absolute gain as with the others. This
value varies from 00 (no set up) up to + 31 and down to –32 (thereby crushing
blacks) in steps of 1.
In the case of NTSC, set up level is referenced to the standard 7.5 IRE pedestal.
5.2.4 Sharpness Adjustment
The SD-210AD has a digital luminance sharpness response control that allows
the user to enhance or attenuate the high frequency components of the
luminance.

behave the same way as in the level control sub menus.
There are seven possible choices: Flat plus three Enhancement and three
Attenuation filters. (Remember, adding sharpness will often add high frequency
noise to the picture as well).
Available gain and attenuation values depend on the Input format selected (see
5.2.7), as follows:
For composite input, gain choices are: + 1.2 dB, + 1.7 dB and + 4.5 dB; while
attenuations choices are: - 1.2 dB, - 1.7 dB and –3.0 dB
Y/C or YUV inputs have the following choices: + 3.3 dB, + 5.7 dB and + 9.2 dB; -
3.0 dB, - 5.7 dB and –8.0 dB
Note: As these last formats don’t require separation, luminance input is usually
cleaner and, generally, gives more processing margin to the user.
