that solves frame rate conversion issues experienced by video scalers. When
video input and output refresh rates differ, occasionally the two rates cross
over each other. The result is a glitch or image freeze on the display. AFL
solves this problem by locking the output frame rate to the input frame rate.
an advanced motion prediction and compensation method that treats motion
content and still content with different algorithms to yield high fidelity images.
These advanced, patent pending, film mode processing feature helps
maximize image detail and sharpness for video sources that originated from
film. When film is converted to NTSC video, the film frame rate has to be
matched to the video frame rate in a process called 3:2 pulldown. Jaggies and
other image artifacts can result if conventional deinterlacing techniques are
used on film-source video. The ISM's advanced film mode processing
recognizes signals that originated from film. The ISM then applies video
processing algorithms that optimize the conversion of video that was made
with the 3:2 pulldown process. This results in richly detailed images with
sharply defined lines.
A similar process is used for PAL film-source video.
