Table 12
Conversion table between dezV and DEZVM / DEZVS
The vertical compression block can be switched off by setting DEZVM/DEZVS equal “0”
and INTVM/INTVS=0. In this case it is possible to switch on a low pass filter for the
chrominance data path by the I²C Bus parameter CHFILM/CHFILS (I²C Bus parameter,
03h, 25h). If CHFILM/CHFILS is equal to “0” or “2” the vertical filter for the chrominance
is switched off. If CHFILM/CHFILS is equal to “1” or “3” the vertical filter for the
chrominance is switched on (Table 17 "Input write I²C Bus parameter CHFILM/
CHFILS" on page 38).
In addition a vertical peaking of the input signal is possible.
