Product Description
On June 24, 1998 Yves Faroudja was awarded the
prestigious Charles F. Jenkins Lifetime Achievement Award from the Academy of Television Arts and Sciences for his video processing technology. Faroudja’s first Emmy was awarded in 1991. Some of this award winning technology is used in the DVP3000.
The Faroudja DVP3000 Digital Video Processor/Scaler is the ideal solution for optimizing the growing selection of display devices that require high performance results.
The unit is a precision video instrument used to convert 480i interlaced signals into high­resolution progressively scanned images .
The DVP3000 removes typical video processing artifacts while also increasing color purity and image detail by using a process called Picture Plus™ technology. (See page 3 for details).
It offers unique flexibility to select different scan rates and aspect ratios to get the most out of the display device whether it be a CRT, LCD, DLP or Plasma based display.
The DVP3000 is a full function Scaler that offers computer scan rates of VGA, SVGA, XGA and SXGA plus HDTV scan rates of 1080i, 720p, 960p (Quadrupling) and even 1080p. This flexibility allows for optimization of any type of display technology. CRTs can be set to provide maximum scan lines with maximum detail and any pixel-based display can be connected at the projector’s native resolution.
provides perfect image geometry no matter what type of source is used, either Letterbox, Anamorphic or 4:3. Since the DVP3000 manipulates the aspect ratio, the display only needs one memory.
The DVP3000 accepts all types of interlaced sources; Composite, S-Video and Component. It is also forward compatible with future sources including the progressive output from DVD players by upconverting the signal to a higher scan rate. It also has connections for any high resolution source such as HDTV or Computer to pass-through to the display while offering controls for Contrast and Color.
Two key new technologies are implemented in the DVP3000. DCDi TM, Directional Correlation Deinterlacing, prevents the introduction of motion artifacts from video original material such as sporting events. The Scan-Lock TM Bandwidth Expansion circuit optimizes the detail settings for each scan rate.
The DVP3000 offers a 10-bit color decoder for noise free color reproduction. A Time Base Corrector helps to stabilize unstable sources such as VHS tapes.
Another key feature for optimizing the image is internal Aspect Ratio selection. This
The DVP3000 comes with a multi-function smart remote control that allows for both toggle and direct access control of all functions plus has the commands for seven other theater devices already loaded into its memory.

Product Description
The greatest benefit of the DVP3000 is the image quality, a result of a complex three stage process called Picture Plus™ Technology.
Stage 1 – Color Decoding: Adaptive Comb Filter­Cross 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 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 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 TM 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 typically found only with high-bandwidth production studio original material.
The DVP3000 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.

Rear Panel I/O
Remove the DVP3000 unit from the shipping container and examine it for any signs of shipping damage or missing items (check inventory list below). All shipping materials should be saved if the unit is to be moved or returned for service.
Installation The DVP3000 processor is designed to be either
placed on a table or rack mounted. If the rack mounting installation kit is to be used, the rack mount ears are mounted by using 3 screws. It will be necessary to support the rear of the unit if it will be shipped in the rack by using rack support rails supplied by the rack manufacturer.
Ventilation
The unit is cooled by a fan located on the top panel. Air is drawn from vents along the sides and bottom of the chassis. These vents must not be blocked. When rack mounted, a minimum of 1.75" (1 rack unit height) of free space is required above and below the unit to allow for proper cooling. A forced air fan should be added to the rack installation if power amps are located in the same air space.

Outputs
This page outlines how different sources and displays can be connected to the DVP3000. Because of the high performance of the DVP3000 it is very important to use the highest quality cables possible, for both input and output signals.
Both the RGB BNC and the D15 Monitor output connections are active at all times and can run two displays simultaneously.
To avoid AC ground loop problems, the source equipment, DVP3000 and projector should all be running on the same AC power line (one correctly rated for the power requirements).
Source Inputs
1. S-Video (Y/C) sources such as DVDs, Satellite systems, S-VHS tape decks (when using S-VHS tapes only), Hi-8 tape decks.
2. Composite video sources such as Laserdisc players, cable TV, VHS tape decks, 8mm tape decks.
3. Interlaced Component video sources such as DVDs and professional tape decks. Progressive Component signals from DVDs are also connected here.
5. D15F connector for use with computer monitors or to a second display device.
6. BNC connectors for main output to display devices. For YPrPb outputs use: Red = Pr Green = Y Blue = Pb
Note: If HDTV or Computer signals are to be used, the projector must have separate H & V sync cables installed.
Control
7. 12V trigger to activate automatic screen relays.
8. IR receiver connection allows for use with external IR receivers so unit can be installed behind walls.
9. RS232 D9F connection for use with RS232 control systems
10. AC Power connection.
4. High scan rates sources such as HDTV and computers as a pass-through to the projector.
