Preliminary Data Sheet
The maximum line difference LDMAX of the output signals LDACT and LDDEL controls the look up
tables LUTFR/LUTFI in the frame and field difference signal processing path. In this way the
sensitivity of the field and frame differences are adapted to the picture contents. The sensitivity of
the line difference block can be changed by the SVALLI parameter. The line difference will be
quantised to a two bit value. The thresholds are programmable by the parameters THLI2, THLI1
and THLI0.
