gressive display projects a smoother video

 2D Progressive
This function is useful to display fast-
moving images such as sports and ac-
tion films. This mode optimizes the im-
age in a displayed frame.
 3D Progressive
This function is useful to display relatively
slow-moving images such as drama and
documentary more clearly.
This mode optimizes the image by esti-
mating the movement of a number of pre-
ceding and succeeding frames.

clearly. Displays the optimized image of
film transformed with three-two pull down
(NTSC and PAL60Hz) or two-two pull
down  (PAL50Hz and SECAM) enhance-
ment to progressive mode images.
* The film source is a digital video record-
ing with the original encoded as is at 24
frames/second. The projector can con-
vert this film source to progressive video
at 60 frames/second with NTSC and
PAL60Hz or at 50 frames/second with
PAL50Hz and SECAM to play back a
high-definition image.

down enhancement will be enabled only
