VP-12S4 High Definition Digital Projector VP-12S4 High Definition DLP Video Projector After the continuing evolution and success of the VP-12 series, people were asking, how much better can it possibly get? Only
after witnessing the VP-12S4 this can be positively answered. The new Marantz VP-12S4 will give the smoothest, most seamless
and lifelike image ever delivered from a single chip solid state video projector. Sublime components make this video projector
first in his class and will be described below. Texas Instruments HD2+ DLP
®Technology
The VP-12S4 projector is supplied with the already proven platform of Texas Instruments HD2+ DLP chipset. The performance
has been improved by using their DarkChip 3 design, which tightens the space between the mirrors for even less pixelization
than before. In addition this chipset operates at a higher speed, reducing dither noise in low light portions of the image. High-Fidelity Video Processing Engine by GENNUM
®
The crowning achievement on this VP-12S4 is a completely new video processing engine. This new processing chip was
developed by GENNUM (specifically for the VP-12S4) and is the most powerful video processor ever included in a video display
device - consumer or professional. GENNUMs GF9350 10-bit image processing system-on-a-chip (SoC) sets new benchmarks
for video realism and processing flexibility. The GF9350 features GENNUMs latest de-interlacing algorithms with dynamic edge
detection and film mode processing for both HDTV and SDTV interlaced formats. Content adaptive noise reduction & detail
enhancement algorithms remove unwanted noise while improving image detail for a cinematic HDTV experience. It offers true
motion adaptive de-interlacing of all non-progressive sources - HD included - with inverse telecine (3:2 pull down), jagged edge
reduction circuitry, 4:4:4 processing at a true 10 bit color depth (over 1 billion colors displayed) and a new level of flexibility for
the installer including sizing and blanking controls. The VP-12S4 is equipped with a special version of the GF9350 bearing the
Marantz logo.
GENNUM calls the set of technologies offered by the GF9350 VXP, for Visual eXcellence Processing
-„¢. Broadly conceived, VXP
combines four technologies.
TruMotionHD:De-interlacing technology
that makes input signals progressive,
converting them from non-interlaced to
interlaced sequentially. It is compatible
with High- Definition signals (720p,
1080i) as well, and it preserves the high-
resolution effect after progressive
conversion. TruMotionHDalso reduces
chroma upsampling error caused by
MPEG decoders of DVD players.
FineEdge:This technology refers to edge
enhancement (correction and emphasis)
and adaptive processing. This processing
smoothes image edges extremely well,
especially lines running diagonally.PurePixel: The GF9350 uses 10-bit processing for all signal
processing, a technique called PurePixel. 10-bit processing
produces exceptionally better gradation than typical 8-bit
processing, raising the number of colors to a higher order of
magnitude from 16.77 million to more than a billion. Samples
are processed so that input signals sampled at Y:Cb:Cr=4:2:2, for
example, are all subject to data interpolation to produce an ideal
sampling of 4:4:4.
FidelityEngine:Detail emphasis and
noise reduction are provided by what is
called the FidelityEngine. This technology
cuts noise without reducing the sense of
picture resolution. For low-resolution
images that are not sharp, the Fidelity
Engine adds emphasis to details,
producing clarity.
GENNUMs VXP image processors provide stunning image quality by incorporating the worlds most advanced image processing
algorithms. This level of smoothness and film-like realism has been previously only reserved for professional 3-chip type devices
and of course, film.
New custom optics by Konica-Minolta Furthermore, a new lens was added to the already legendary and award winning
lineup of optics from Konica-Minolta. This new lens is a middle throw distance lens
and fits comfortably between the original standard lens (now called the Short Throw)
and the Long Throw lens. All lenses are finished by multi-coating treatment,
eliminating any excessive glare. The fully sealed optics is assembled in Konica
Minoltas clean room, ensuring consistently high-quality images unaffected by dust
throughout a long period of use. The selectable iris is built into the lens of this optical
engine. To improve flexibility we increased the amount of vertical lens shift to allow
mounting as much as 50% of the screen height above the top of the viewable area. ORCA Filtering with DC powered 200 watt SHP bulb Marantz engineers developed a color correction filter called ORCA (the Optical Reproduction of Color Accuracy), that filters out
the excess yellow, creating a very neutral white light that passes through the color wheel. This results in the most accurate color
palette ever achieved in a video projector and has been balanced to meet the HD color space (ITU-RBT709). This is an industry
first and a Marantz exclusive! The light itself is generated by a new bulb that is DC powered. This 200 Watt bulb is brighter and
less prone to flicker than any other lighting technology available. It was successfully introduced at the predecessor of the
VP-12S4. Seven segment color wheel As in the previous generation, it also utilizes the seven segment color wheel. This wheel is used for less dithering of low level
signals and keeping colors accurate at low signal levels. This contributes considerably in the rendering of extremely dark signals,
which makes for an even more pleasing experience, especially for movies. High Definition Multimedia Interface (HDMI) HDMI assures that pristine high-definition images retain the highest video quality from the source all the way to the display. It
employs the same copy protection technology as DVI and supports HDCP, only exchanging signals with units certified
compatible. The outlets of HDMI terminals are slightly smaller than those of DVI terminals. The HDMI is backward-compatible
with DVI. Marantz gives the consumer full digitalized interconnection from source to display. View it yourself Reading about it does not do the VP-12S4 justice, so experiencing it yourself, at your nearest authorized Marantz dealer, will give
the right credits to this magnificent DLP projector.
