Deinterlace There are several different deinterlacing algorithms. Choose the setting that best matches the content you are watching. Select "Deinterlace" from the "Options" menu on the menu screen. For operating the menu screen, see page 33. Main Menu Selected item DCTI Video on film (VOF) Film Mode Description Enhances video by replacing the edges of the video with edges that have steeper rise and fall times. DCTI turns sloped or sinusoidal waveforms into rectangular or square waveforms with the same duty cycles and peak-topeak amplitude. It is useful for 4:1:1 video sources. The range is from 0 to 7. Identifies video artifacts while in film mode. VOF attempts to repair the artifacts using the low-angle interpolator while remaining in film mode. Reproduces the image of the film source clearly. Displays the optimized image of film transformed with 3:2 pull down (NTSC and PAL60Hz)or 2:2 pull down (PAL 50Hz and SECAM) enhancement to progressive mode images. Note • In PAL50Hz or SECAM, the 2:2 pull down enhancement is enabled only in film mode, after the film source has been entered. Easy to Use Functions 49

are watching.
Select “Deinterlace” from the
“Options” menu on the menu screen.
For operating the menu screen, see

In PAL50Hz or SECAM, the 2:2 pull down
enhancement is enabled only in film mode,
after the film source has been entered.

Description
DCTI
Enhances video by
replacing the edges of the
video with edges that have
steeper rise and fall times.
DCTI turns sloped or
sinusoidal waveforms into
rectangular or square
waveforms with the same
duty cycles and peak-to-
peak amplitude. It is useful
for 4:1:1 video sources. The
range is from 0 to 7.
Video on film
(VOF)
Identifies video artifacts
while in film mode. VOF
attempts to repair the
artifacts using the low-angle
interpolator while remaining
in film mode.
Film Mode
Reproduces the image of
the film source clearly.
Displays the optimized
image of film transformed
with 3:2 pull down (NTSC
and PAL60Hz)or 2:2 pull
down (PAL 50Hz and
SECAM) enhancement to
progressive mode images.
