in the upconverter; range: 0 to 3.5 in steps of 0.5 line; should remain
at logic 0 in normal operation
roll back factor ranging from 0 (use 0% of estimated vectors) to 16
(use 100% of estimated vectors)
fallback (double memory or single memory type fallback)
single memory film mode control (double memory or single memory
type); should be set in single memory film mode to ensure that only
original lines are selected as output when UpcShFac is 0 or 32

de-interlacing (full FALCONIC or single memory type
de-interlacing)
Bits 3 and 4 are used to control sensitivity to local vector smoothness
(0 = sensitive to unsmoothness, 3 = hardly sensitive to
unsmoothness). Bits 5 to 7 define the maximum contribution of
non-motion compensated pixels to the output

upconverter goes into protection mode (0, 1, 2, 4, 8, 16, 32 or 64).
A value of 0 switches off the possibility to go into protection.
