The greatest benefit of the DVP5000 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.
The separation of 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 video and S-Video sources
have been filtered to reduce the amount of
signal (bandwidth) for recording and transmis-
sion 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 produc-
tion studio original material.
Stage 2
–
Film and Video DCDi Motion
Tracking
Changing the structure of the video source
from interlaced to progressive is a difficult
process when the signal contains any
motion.
For material originated from video cameras,
such as sporting events, DCDi ™ is used.
Directional Correlation Deinterlacing prevents
the introducing of jagged edges and blurring.
For video converted from film cameras,
the
patented 3/2 pull-down detection
circuit
is used.
These circuits allow the unit to recombine the
interlaced film or video frame back into its
original structure limiting the introduction of
motion errors. Horizontal, vertical and even
angled lines are correctly reproduced.
Stage 3
–
Luminance Bandwidth Expansion
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 typ-
ically found only with high-bandwidth produc-
tion studio original material.
The DVP5000 applies the new Scan-Lock
feature. The Bandwidth Expansion circuit is
applied after the scaling stage. This allows
for the circuit to optimize, or “Lock” to each
scan rate. The optimized settings are
automatically recalled each time the scan
rate is selected.
It is the combined affect of all three stages that
yield the superior image quality only Faroudja
can offer, regardless of scanning rate. 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.
