Model DVC-3 Digital Video Coach
1. Introduction
1.1 General
Thank you for purchasing Hall Research Technologies’ Model DVC-3
(Digital Video Coach-3), a video test pattern generator for high-
resolution display devices.
The unit provides DVI, PC (VGA through SXGA), and HDTV
Component Video (Y, Pb, Pr) outputs. The DVC-3 features 28 static
and dynamic video test patterns specially designed for testing,
calibrating, and troubleshooting high end video gear and A/V
installations.
In addition to all of standard PC resolutions and refresh rates (up to
SXGA at 85 Hz), it is capable of providing HDTV outputs from 480p
to 1080p both in DVI digital and in YPbPr formats. The OSD indicates
output resolution and refresh rate settings. Among the available 28 test
patterns are: color bar, multi-burst, circle, and crosshatch. The OSD
will disappear from the screen, to prevent screen burn-in, after a time
period of 8-20 seconds depending on the pattern being displayed.
The DVC-3 comes in a sturdy metal case and it includes DVI, VGA,
and VGA-to-Component cables to handle most high-end testing and
installation requirements. The DVC-3 is ideal to use with LCD,
plasma, CRT monitors, and projectors that are equipped with PC,
Component, or DVI inputs.

2. Installation
1. Plug the supplied AC adapter to the Power input connector located
on the rear of the unit. Use the supplied adapter or a 100%
equivalent only. There’s a small green LED that turns on when the
unit is powered up.
2. Included in the package are all the cables that you may need: a
DVI cable, a VGA cable, and a HD15 to component Cable (shown
below)
Choose and use the cable required for your application.
3. Operation
¾
The front panel of the unit is pictured below:

There are two output connectors on the box that are both active
simultaneously. One VGA (HD15) and one DVI.
The VGA output is dual purpose. It can output standard RGBHV
VESA signals similar to those that are output by most PC’s, as
well as YPbPr component video output. The output mode of the
HD15 connector is determined by a small slide switch.

¾
There’s an indicator LED next to the slide switch that comes on
when the output resolution is one of the standard HDTV
resolutions AND the slide switch is in YPbPr.
To operate the unit you use 3 push-button switches. One button is
to walk through all the resolutions and refresh rates that are
available (it is labeled OUTPUT MODE). The other 2 buttons are
used to change the video pattern being generated there are 28
patterns (these buttons are labeled + and -).
¾
To quickly jump to a known resolution (instead of walking
through them one by one using the MODE switch), pressing two
buttons simultaneously jumps to a given resolution/refresh rate.
Pressing the left two buttons gets you to XGA at 60 Hz (and
subsequent pressing of the MODE button will take you up from
there). Pressing the right two buttons gets you to 480p (a standard
HDTV mode). Please note that in these HDTV modes, the DVI is
outputting the proper signal and if the slide switch is in VGA you
are getting RGBHV output and if in YPbPr you get component
video (with sync on Y) and the LED will light to indicate that the
unit is outputting a proper YPbPr output.
¾
¾
If the OSD is not displayed, pressing the MODE button once will
redisplay the current resolution. The resolution will only change
when the OSD is displayed.
Here is a list of output resolutions that the Mode button will walk
you through (there’s an on screen display OSD which indicates the
mode setting):

As mentioned earlier the + and – buttons change the video output
screen among the different patterns that are provided. Most
standard patterns are included such as: Color bars, Color bar and
Multi-burst on same screen, Grey-scale, Checkerboard, Circle,
Crosshatch, etc. However several unique and interesting patterns
are also available. There are 2 dynamic patterns one which
changes the screen smoothly from black to full white, and another
which is a checkerboard that switches white and black squares
about once per second (this pattern may be useful for viewing
compression artifacts in a situation where video is going to be
compressed for lower bandwidth transmission or processed in
some other way).
¾
There are 2 patterns with Red Green and Blue horizontal bars over
white and black background that are great for video distribution
testing especially when long cables (either multi-coaxial, or
Category5/6) are used. The high frequency loss in the long cable
runs will cause the color of the horizontal bars to smear to the
right. Hall Research along with a few other manufacturers of high
quality video amplifiers and extenders have provisions for
compensating for these losses (usually be means of dip switches or
potentiometers). These two patterns are perfect for these types of
installations. The user can set the amount of compensation
perfectly!
7
Model DVC-3 Digital Video Coach
The same 2 patterns are also useful for Video-over-UTP Category
cable both for the high-frequency loss compensation (above
paragraph), but also for Skew Compensation for those devices that
give you this flexibility. The right and left edges of the RGB bars
should vertically line-up. Again, this pattern gives you a
convenient means for making this adjustment.
Operation Summary
‰
To change the resolution being produced press the OUTPUT
MODE button repeatedly. The output screen has an OSD to
indicate the resolution and refresh rate settings
NOTE: It is possible to set the output resolution to one that
your monitor does not support. In this case you my not get a
screen. You can either keep pressing the OUTPUT MODE
button as it eventually goes through all the available outputs
in a circular fashion, or use 2-button “Quick Select”
combination to jump to a specific output immediately.
‰
‰
To change pattern press the + or – keys.
To get analog high res. component video output at the HD15
connector (instead of VGA), slide the switch to YPbPr and
press the 480p “Quick Select”. The LED will turn on to
indicate that there is a valid component output signal present.
NOTE: If the LED is not on that means you are not getting a
proper analog component output! Either the output MODE is
not at one of the HDTV settings, or the slide switch is not in
correct position.
NOTE: The DVI connector outputs all available resolutions
(both PC and HDTV)
‰
When you change the output, the DVC-3 memorizes your
settings after 8 seconds and the next time the unit is tuned on
it will recall the memorized settings.
