If you are viewing this manual in PDF form, you can click on any link to jump
directly to a referenced topic. Links are identified by the colored, underlined type.
For example, the chapters listed above are links and will take you directly to that
chapter.

Chapter 1
Introduction
System Overview
The STEALTH system is a modular LED display product that allows for full motion
video to be displayed on high resolution STEALTH panels.
The STEALTH panels are lightweight and rapidly deployable. A nearly 60 percent
transparent design makes it easy for set pieces or even other display devices to
remain visible behind it allowing for a number of different creative effects.
STEALTH is comprised of the following hardware components: VP1 - Video Processing Unit
(p. 2-2) SP1 Signal Processing Unit
(p. 2-4) DD1 Data Distribution Unit
(p. 2-8) PDB-3 Power and Data Distribution
(p. 2-9) DSU Data Supply Unit
(p. 2-12) STEALTH Panel
(p. 3-5)
The STEALTH system is capable of handling many types of video signals including:
DVI
SD-SDI
HD-SDI (limited resolution, see
page 2-2
)
Component
S-Video
Composite
The VP1 takes one of the above signals and converts it to the proper format for
input to the SP1. The SP1 requires a 1024x768 Digital Visual Interface (DVI) signal at
60 Hz with high (+) or low (-) vertical sync.
N O T E
If you already have a properly formatted DVI signal for the SP1 (1024x768 @ 60 Hz),
you do not need the VP1.
Throughout this manual, screen sizes and/or pixel dimensions are referenced in the
commonly used form of 1024x768. The first number is the horizontal value and the
second number is the vertical value. For example, the DVI input signal to the VP1 is
1024 horizontal pixels by 768 vertical pixels and is represented as 1024x768.
The SP1 has 2 fiber optic outputs each with a resolution of 1024x256 pixels. One or
both SP1 outputs are connected to the DD1. The DD1s job is to slice up the signal
into 400x80 pixel chunks which are then routed to the individual STEALTH panels
via the PDB-3. STEALTH® v2 Users Guide

Chapter 1
Introduction
The PDB-3 contains 2 DSUs, each with 4 outputs. The DSU handles the final
conversion of the video signal into 16x80 blocks which connect to a column of 5
STEALTH panels. Each STEALTH panel is an individual array of 16x16 pixels.
The following figure illustrates the basic signal flow of the STEALTH system. Unless
otherwise noted, the numbers shown are pixel dimensions.

Processing Components
VP1 - Video Processing Unit
The VP1 is a Video Processing Unit capable of accepting several video formats and
outputting a 1024x768 pixel DVI-D signal. The VP1 is operated via serial control
from a PC using the supplied LedGuru software. Refer to
LedGuru Software
, (p. B-1)
for information on controlling the VP1 via the LedGuru Software.
The following is a list of the video signals that the VP1 accepts:
DVI
SD-SDI
HD-SDI (limited resolution, see note below)
Component
S-Video
Composite
N O T E
If you already have a properly formatted DVI signal for the SP1 (1024x768 @ 60 Hz),
you do not need the VP1.
HD-SDI input video is limited to 720x486 resolution.
