Additional information
• Film based software conversion
Film shows an image by displaying an entire
image at 24 frames per second. When you
watch a film on television, the television
displays every other line of the frame as a
field, thus reducing information level and the
clarity of the film image.

clarity of the film image.
This player solves this problem by
increasing the speed at which the frames are
displayed, consecutively showing 3 identical
frames followed by 2 identical frames in the
time that it normally takes to show 2
consecutive frames. The end result is that the
24 frames per second are increased to 60
frames per second, which is the speed at
which Progressive video signals are shown.

This not only allows film to be shown in a
frame based format, it also increases the
clarity and sharpness which is unique to
Progressive format images.

Interlace format (page 76)
.terlace format sho ws every other line of an
image as a single “field” and is the standard
method for displaying images on television.
The even number field shows the even
numbered lines of an image, and the odd
numbered field shows the odd numbered
lines of an image.

(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.

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 second. 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.
