Function
Adjust the clamp pulse width of Cb/Cr at YCbCr signals.
It usually uses on BUS:[0000].
Adjust the digital-clamp-phase for C/Cb/Cr.
(S-Video/YCbCr inputs.)
It usually uses on BUS:[011].
Fine tune the digital-clamp-pulse-width for C/Cb/Cr.
(S-Video/YCbCr inputs.)
It usually uses on BUS:[011].
This is adjustment of time constant of Digital-clamp-C.
It can set ON/OFF and three-kinds.
Setup color killer function.
[0]: Active (normal) [1]: Killer become OFF always.
Level of color-killer-ON is set up. [000]:killer sensitivity is
max.[111]: killer sensitivity is minimum.
Reference-level of ACC(auto color control) is set up.
Level by ACC becomes smallest when it is set up in 000.
Setup of dot-reducer at the horizontal edge.
When it is turned on, dot of the part of H is reduced.
It has an effect as below for PAL system.
When the horizontal lines of the front and the rear have color
and edge element,and the horizontal line of center has no color,
it drops Y signal level for calculated result. Therefore it
occurs dots of black in spite of white and gray picture.When
COMB+ is on, it can decrease this noise.
It usually uses ON, when PAL signal.
Setup of 1LINE-DOT-improver in the YCS block. [1]:ON [0]:OFF
It can reduce the dot,when only 1-line has a color signal.
Comb control in 443NTSC is changed. [1]:2H comb [0]:1H comb
Cross-color will reduce when 2H-Comb is selected.
Setup Y-trap performance for SECAM.
