second. Film based software is derived from
film and displays images at 24 frames per
second. In order for these images to appear
natural on your screen when output in
PROGRESSIVE mode (60 frames per
second), the progressive video signal needs
to be converted to match the type of DVD
software that you are watching. For more
information about conversion modes, see
"Progressive Conversion Methods of Film
Based and Video Based Software."
AUTO This will automatically detect if
you are playing Film based or
Video based software and
convert the signal to the
appropriate conversion mode.
Normally select this position.
VIDEO
This will set the conversion
mode for Video based software,
regardless of the type of software
that you are playing.
Notes
N
Some DVD software contains both Video and Film.
For instance, DVDs of movies may contain the
movie taken on film, and a "Making of" sequence
taken on video.
N
When you play video based software with
progressive signals, sections of some types of
images may appear unnatural due to the conversion
process when output through the COMPONENT
VIDEO OUT jacks. Images from the S VIDEO OUT
and LINE OUT (VIDEO) 1/2 jacks are unaffected as
they are output in the interlace format.
Progressive Conversion Methods of
Film Based and Video Based
Software
This player converts video based software
and film based software in the following
manner.
Video based software conversion
Video shows an image by alternately
displaying every other line of an image (field)
at 30 frames (60 fields) per second (Interlace
format).
The Interlace format displays 30 frames (60
fields) per second by displaying every other
line of the image, causing scanning lines to
appear across the image. Furthermore, since
only half of the image is shown at once, the
amount of information contained in an image
is limited.
The Progressive format displays 60 entire
frames per seconds. The player accomplishes
this by converting each field into a frame by
using either a field-based conversion method
or a frame-based conversion method. The
appropriate method is automatically selected
by the player according to the movement of
the images on the screen. If the movement on
the screen is slow, the frame-based
conversion method borrows adjacent field
information to fill in the missing information.
If the movement on the screen is rapid, the
field-based conversion method creates the
missing information by predicting the
movement of the images on the screen from
field to field. The end result is an image that
is higher in quality when compared to the
Interlace format.
