ES DVD Players 2005, Version 4.0 Page 15
The typical interlaced video frame includes both still and moving pixels.
Sony Pixel-by-Pixel Active I/P conversion applies separate processing
for each.
Pixels for still objects are the easiest to handle. When objects are not
moving, the player can simply use the corresponding pixel from the previous
field. Because there is no motion, these pixels will match perfectly with the
current field, creating a seamless progressive scan output.

STILL PIXEL PROCESSING
Pixels for still objects are simply created from the corresponding pixel in
the previous field.
Pixels for moving objects are created by composing pixels from scanning
lines immediately above and below within the same field. Because all
information comes from the same 1/60-second slice of time, this suppresses
motion artifacts. While this process does not result in the full improvement in
vertical resolution, the human eye is less sensitive to detail in moving objects.
So the overall effect is a stunning improvement in image detail, clarity and
solidity.
