Table 16
Conversion table between dezH and DEZHM/DEZMS
The horizontal compression/expansion block can be switched off by setting DEZHM/
DEZHS equal “0” and INTHM/INTHS=2048. 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 “1” the horizontal filter for
the chrominance is switched off. If CHFILM/CHFILS is equal to “2” or “3” the horizontal
filter for the chrominance is switched on. The table below shows the different settings of
CHFILM/S.
