X X X X X X X X Global Mean Square Error (MSE) = summation within a field period of
squared differences in comparing vector shifted video from frame
memory (FM2/3) with new field input (FM1) in those lines coinciding
with new field lines. The window for the measurement is kept at
40 pixels horizontal and 20 field lines vertical from the border of the
video. Measurements is only done in fields where the de-interlacer is
active, otherwise reading is zero. In field doubling mode, MSE is zero
at the end of every new input field.
X X X X X X X X Global Motion Trajectory Inconsistency (MTI) = summation within a
field period of squared differences comparing shifted video from frame
memory (FM2/3 output) with filtered data that is rewritten to the frame
memory (FM2/3 input) in those lines coinciding with new field lines.
The window for the measurement is kept at 40 pixels horizontal and
20 field lines vertical from the border of the video. Measurement is
done only in fields where de-interlacer is active, otherwise reading is
zero; in field doubling mode, MTI is zero at the end of every new input
field.

X X X X X X X X Vector temporal consistency = summation over a field period of
absolute differences of horizontal plus vertical components of vectors
newly estimated for each block compared with those vectors
estimated in the previous run at the same spatial block position.
It should be noted that a lower figure implies better consistency.
X X X X X X X X Vector spatial consistency = summation over a field period of absolute
differences of horizontal and vertical components of vectors compared
with those of the neighbour blocks (L, R, U and D); in the comparison,
all vector data is used from the previous estimator run. It should be
noted that a lower figure implies better consistency.
