Interlace format (page 72)
Interlace format shows 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

Progressive conversion method (page 59)
• 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).

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.

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
frames per seconds. The player accomplishes

using either a field-based conversion method

Interlace format.
• 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.

field, thus reducing information level and the
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.

Progressive format images.
