SDA 9400
LPFIP: Lines per field of the input signal - amount of lines between two input V-Syncs
time to close = time(field(interlaced)/frame(progressive)) * number of active lines / (lpfip/256)
e.g. time to close = 10 ms * 576 / (312/256) = 4.7 s
time to close = time(field) * number of active lines / (lpfop/128)
