Progressive Conversion Methods of Film
Based and Video Based Software
This player conver ts video based softwar e and film based
softwar e in the following manner .
Video based software conversion
Video shows an image by alter nately displaying ever y
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 acr oss the image.
Further more, since only half of the image is shown at
once, the amount of information contained in an image is
limited.
The Progressive for mat displays 60 entir e 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 accor ding to the movement of the images on the
screen. If the movement on the scr
based conversion method makes bor
information to fill in the missing information. If the
movement on the scr een is rapid, the field-based
conversion method cr eates the missing infor mation by
predicting the movement of the images on the scr
field to field. The end r esult is an image that is higher in
quality when compar ed to the Interlace for mat.

Film based software conversion
Film shows an image by displaying an entir e 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 r educing infor mation level and the clarity of
the film image.
This player solves this pr oblem by incr easing the speed at
which the frames ar e 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 ar
60 frames per second, which is the speed at which
Progressive video signals ar e shown.
This not only allows film to be shown in a frame based
format, it also incr eases the clarity and sharpness which is
unique to Pr ogressive for mat images.
