Noise reduction for the
vertical pulse of the parent
channel (should be set to
‘1’ under normal
conditions).
If the check for the correct
TV standard is active a full
frame display is only
possible if the number of
lines is exactly according
the TV standard:
312.5 (50 Hz)
262.5 (60 Hz)
Doubling of the gain if a
sufficient SECAM decoder
without delay line is used
