The greatest benefit of the DVP2200 is the image
quality, a result of a complex three stage process
called Picture Plus™ Technology.
Stage 1 – Color Decoding: Adaptive Comb Filter-
Cross Color Suppression - Bandwidth Expansion
In order for the display to create an image, it
must receive Red, Green and Blue signals. To
separate RGB from a composite or S-video
signal is called decoding. This process, usually
done incorrectly, introduces many errors into the
picture. The most visible errors are called Dot
Crawl, seen as moving dots along color edges,
and Rainbow patterns, seen as a moving rainbow
over fine lines such as patterned shirts a news
anchor might wear.
Faroudja’s patented 10-bit Adaptive Comb
Filter and Cross-Color Suppression circuit
eliminates these errors yielding much improved
color purity and edge detail even in scenes with
fast motion.
Most composite and S-Video video sources have
gone through some filtering to reduce the amount
of signal (bandwidth) for recording and
transmission purposes. This can significantly
reduce color edge detail causing colors, such as
Red, to blur onto White backgrounds.
Faroudja’s Patented Color Bandwidth
Expansion circuit actively monitors the color
signal and significantly increases color edge
detail to levels typically found only in production
studio original material.
Stage 2 – Film/Video Motion Tracking
Changing the structure of the video source from
interlaced to progressive is a difficult process
when the signal contains any motion.
Faroudja’s patented Film/Video Motion logic
actively tracks the signal and activates different
motion tracking algorithms depending if the
signal originated from a video or film camera.
This approach to motion allows the unit to
recreate the interlaced film or video frame back
into its original structure limiting the introduction
of motion errors. Horizontal, vertical and even
45° angled lines are correctly reproduced.
Stage 3 – Luminance Bandwidth Expansion
The human eye has excellent ability to judge
detail with black and white (luminance)
information and limited ability with color
information.
Faroudja’s patented Luminance Bandwidth
Expansion circuit is able to greatly increase the
perceived resolution of any video source by
reducing the time it takes the signal to change
from one level to the next (called Rise-Times).
This normally can only be accomplished by
increasing the bandwidth of the signal.
Faroudja’s unique circuit yields detail levels
typically found only with high-bandwidth
production studio original material.
It is the combined affect of all three stages that
yield the superior image quality only Faroudja
can offer, regardless of what scanning rate the
processor is operating at. By never
compromising at any point in the circuitry,
Faroudja processors will yield unparalleled image
quality, matching 35mm film in color, detail and
dramatic impact.
