MSF[18:0]
UC
Represents the number of pixels per smallest
active field divided by a scaling factor
required to estimate same frame detection.
A higher value also means vertical edges will
have more effect on the detection of same
frames. The equation is as follows:
MSF = #active_pixels_per_smallest_field / 2

DIFF3T[18:0]
UC
Represents the number of active pixels per
smallest field divided by a factor required to
estimate the odd and even pattern detection.
The equation is as follows:
DIFF3T = #active_pixels_per_smallest_field /2
