Description
The FLI2300 is a highly-integrated digital video format converter for DTV and DVD
applications using patented de-interlacing and post-processing algorithms from Faroudja.
The FLI2300 can capture and process standard definition PAL, NTSC data, 1080i and 720
High Definition data, PC graphics data, and most non-standard resolutions in either
interlaced or progressive scan format. The maximum input clock rate is 75 MHz.
Interlaced video signals are converted into progressive scan signals using per-pixel Motion
Adaptive De-interlacing. Faroudja DCDi incorporates Faroudja’s patented and Emmy award-
winning Edge Correction technology in which video is analyzed on a single-pixel granularity
to detect presence or absence of angled lines and edges. These are then processed to
produce a smooth and natural looking image without visible artifacts or “jaggies”. Patented
FilmMode processing is used for proper de-interlacing of 3:2 and 2:2 pull down material.
Edit Correction for film content is continuously monitored for any break in sequence caused
by “bad edits” and quickly compensates for the most effective reduction in artifacts.
These features are coupled with highly flexible scaling, a wide variety of aspect ratio
conversions, and other special video enhancing features to produce the highest quality
image.

Front-end processing
–
Motion Adaptive Noise Reduction—Improves picture quality for off-air material
–
Cross Color Suppressor—Removes cross color artifacts in composite video
signals due to poor Y/C separation in standard 2D video decoders, enabling 3D-
type performance

Tearless frame rate conversion, 50/60/72/75/100/120 Hz
De-interlacing
–
Per-pixel Motion Adaptive De-interlacing (MADi)
–
Patented FilmMode processing—Used for proper de-interlacing of 3:2 and 2:2
pulldown material
–
Edit Correction—Film content is continuously monitored for any break in sequence
caused by "bad edits" and quickly compensates for the most effective reduction in
artifacts
–
DCDi by Faroudja—Video is analyzed on a single pixel granularity to detect
presence or absence of angled lines and edges, which are then processed to
produce a smooth and natural looking image without visible artifacts or "jaggies"
