Non-interlaced lines are not doubled.
Non-interlaced lines are doubled in height.
Black lines are inserted between each non-interlaced lines.
Odd and even field pairs are combined to single frame, display update rate
becomes effectively halved (50Hz -> 25Hz).
Odd and even fields are shown alternately. When odd field is shown, previous
even field is not changed or erased and vice versa.
Same as above but instead of not changing previous field, previous field is
blanked. Sort of emulates really really short persistence CRT display.
