Description
The FLI2200 is a single chip implementation of Faroudja
Laboratories’ award winning deinterlacing and post-
processing algorithms that produce the highest quality
progressive video output from a variety of interlaced video
inputs including 525/60 (NTSC) or 625/50 (PAL or SECAM).
It uses patented and patent pending motion-adaptive
deinterlacing that selects the optimal filtering on a per-pixel
basis. This includes detection and proper interleaving of 3:2
and 2:2 pulldown for film-base sources, including continuous
monitoring and compensation for bad edits that occur
frequently in broadcast material due to poor scene cuts or
insertion of commercials. Video material is processed by a
set of content-sensitive spatio-temporal filters that adapt to
the appropriate direction for smoothest interpolation using
the patented Faroudja DCDi™ algorithm. The FLI2200 also
includes motion-adaptive cross-color suppression that
removes highly objectionable coloration artifacts produced
by commonly used video decoders. Its internal processing
uses 10 bits per channel to maintain the highest quality. Its
inputs and outputs are 10 bits/channel for best quality but
also supports 8 bits/channel for more cost-sensitive
applications. The FLI2200 requires 4 MB of low cost SDRAM
for best quality deinterlacing, but it can also be operated in
an optimized intra-field mode without memory for more cost-
sensitive applications. This makes possible the use of a
single design for both high-end and low-end applications.
The FLI2200 integrates a number of functions to provide
maximum flexibility in a low cost configuration. This includes
an on-chip clock generator, SDRAM controller, display
controller, input and output color-space converters. It uses
a standard 2-wire serial control interface for easy control
and access to the registers.
The FLI2200 can be connected without glue logic to the
FLI2000 video decoder and FLI2220 Enhancer and OSD
Generator to produce the highest quality video pipeline for
premium applications. It is also fully compatible with other
decoders having a ITU-R BT 656 output format.
