Overview of the VisionPro™Video Processor
The primary functions of the VisionPro are to act as a video switch, convert the selected
interlaced video input to progressive video and then scale the video resolution to match
the optimal resolution for the display. Converting interlaced video to progressive video is
referred to as “deinterlacing.” It is also sometimes called “line-doubling,” but this term is
misleading, so the term deinterlacing is preferred.
Interlaced video has been in use for more than 50 years and is still the most common
video format. It displays half of the lines of picture information each sixtieth (or fiftieth)
of a second. Each half of the image is called a field and displays either all the even lines,
or all the odd lines. So, an entire image, called a frame, takes a thirtieth (or twenty-fifth)
of a second to display on the screen. An “i” suffix on the resolution specification is used
to indicate interlaced formats.
In contrast, progressive video presents each frame as a whole, dramatically improving
image quality. A “p” suffix on the resolution specification is used to indicate progressive
formats.
The VisionPro is comprised of four major functional sections:
•Input selection, conversion to digital, and video decoding
•Deinterlacing
•Filtering and scaling
•Conversion of the digital video to analog video
These functional blocks are shown below.

Composite and SVideo inputs automatically select between NTSC, PAL and SECAM
formats. Component inputs accept standard-definition interlaced video. The selected
input is first sent to the TV decoder, which digitizes the video using a 10-bit analog-to-
digital (A/D) converter. The digitized data is then decoded into standard digital video.
The digital video is then deinterlaced into a progressive format. To accomplish this, four
input fields are used to determine the contents of each frame. For progressive sources, the
original frames are reassembled using 3:2, or 2:2, pull-down reconstruction. For video
sources, interlaced-video artifacts are detected on a per-pixel basis. Using the result of
this detection, the source pixels are combined into the best possible progressive image.
Proprietary scaling algorithms are used to scale the resulting progressive video to the
optimal size for the display. Unlike many video processors, which are limited to a few, or
even a single output resolution, the VisionPro is programmable from 480 to 1080 active
scanlines, in scanline increments. Output video is over-sampled to provide the best
possible image quality. Video oversampling provides the same benefit that audio
oversampling does for music CDs. That is, it produces the most-accurate reproduction of
the video signal possible.
As part of the scaling process, digital filtering is used to enhance the image detail. This
enhancement allows standard definition inputs, such as DVDs, to appear to be much
higher resolution, even when viewed on the large screen sizes common in home theaters.
Image enhancement combined with oversampling allows elements of the image to be
sharper and more precisely placed within the image. This leads to a more three-
dimensional look. In fact, a good way to judge the quality of any video processor and
display combination is to evaluate how “three-dimensional” the images appear for a
given video source. This is because edge enhancement makes the image appear to be
more focused, and improved edge placement gives better “depth cues” to the viewer.
When the digital processing is completed, video is once again converted to analog using
three over-sampled 10-bit digital-to-analog converters (DACs).
To accommodate the various video formats, the output type is programmable. It can be
set to YPRPB, RGBHV, RGBS or RGsB, with programmable sync type and polarities.
For the pass-through input, video is buffered using high-bandwidth video amplifiers. If
discrete sync inputs are used, they can optionally be converted to the same polarity as the
internally generated video sync outputs. This simplifies interconnection with displays that
require a specific sync polarity.
Control can be through an infrared remote control, or the serial RS232 port. Critical
display setup parameters have direct commands. Other functions use an on-screen menu.
The composite, SVideo and component inputs each have two independent configuration
memories, to allow options such as day/night specific modes.

User Commands
Power
Turn power on by pressing ON. Place the unit in standby-mode by pressing STBY.
Input Selection
The eight inputs are numbered from 1 to 8. To select an input, press the respective input
button (1to 8).
Configuration Memory Selection
There are two configuration memories for each input, except pass-through. These are
referred to as type “A,” and type “B,” and are selected by pressing MEMA, and MEMB,
respectively. Each configuration memory is independent of all others. To allow these two
types to be used for mode selection (e.g. day/night), the type remains unchanged when a
new input is selected. (e.g. if input 2 type B is active pressing 3selects input 3 type B).
Check with the installer to determine when to use each type.
Input Aspect Ratio Selection
There are four source aspect ratios: 4:3, letter-box, 16:9, and 1.85. They can be selected
by pressing the 4:3, LBOX, 16:9, or 1.85 buttons, respectively. The and arrow keys
can also be used to step through all four aspect ratios. Use 4:3 for standard full-screen
material. Use LBOX for “letterbox” material, such as analog-television movies shown
with black bars above and below the image. For material labeled as “Enhanced for 16:9
televisions” using 16:9 is generally best.
Some “Enhanced for 16:9 televisions” material is originally 1.85 aspect ratio stretched
vertically to 16:9. This material can be shown at the correct aspect ratio by selecting the
1.85 source aspect ratio.
Note:
Make sure the “television aspect ratio” setting is 16:9 in the setup menu of all source
devices that support this feature (e.g. DVD players), even if the screen is not 16:9.
Image Zoom
After the input aspect ratio has been selected, the image can be zoomed in to better fit the
screen. The zoom function uses the and arrow keys. Each arrow key zooms the
image in approximately 15%, up to 33% total. The arrow key reverses these steps.
On Screen Display
Pressing OK activates the On-Screen-Display (OSD), when the menu is inactive. The
OSD shows the active input, memory, input aspect ratio, and zoom. Pressing OK again
shows additional status information.

Front Panel
The front panel has an LCD status display with backlight, along with power, input select
and aspect ratio select switches, plus an infrared sensor for remote control commands.
The LCD display is illuminated for a short time after infrared commands are received. It
is then darkened to prevent it from being an unwanted light-source. This behavior can be
changed so that the LCD light stays on as a “power-on” indicator by pressing MENU, 0,
9, 2, 5 on the remote and then saving the change, as described in the Installation
Commands section, to make it permanent to make it permanent.

Rear Panel
All connections are made on the rear panel, which is shown below.
The connections are:
•RS-232 CONTROL: If used, connect to an external RS232 control device.
•INPUT 1 to INPUT 8: Connect inputs as described below.
•OUTPUT VIDEO and OUTPUT SYNC: Connect to the display as described below.
•AUX: Auxiliary control (power-on output, or power-on input).
•POWER: Connect to external 5 volt DC power supply.
The RS232 serial port allows commands and status to be communicated with an external
device. This connector is the same as a PC DB9 serial port, except it does not use flow-
control signals. If connecting to a PC, use a female-to-female DB9 null-modem cable.
All video connections use female BNC jacks for the best mechanical and electrical
connection. Because of this, conversion adaptors, or cables, are required for many source
components. Three RCA-female to BNC-male adaptors, two SVideo to BNC-male cables
and two sets of three RCA-male to BNC-male cables are provided. These are used for
composite, SVideo and component sources, respectively. The three RCA-female to BNC-
male adaptors can also be used for another component input, if no composite inputs are
used. Additional cables may be purchased at the www.lumagen.com website. Note that
the type of each input must be programmed as described in the Input Type section.
The connections for each input depend on the source type. Connect composite video
sources to the Y input. Connect SVideo Luma (Y) and Chroma (C) channels to the Y (or
G/Y) and C (or C/PRor R/C/PR) inputs, respectively. Connect component Luma (Y),
chroma-red (PR) and chroma-blue (PB) channels to the Y (or G/Y), C/PR(or R/C/PR) and
PB(or B/PB) inputs, respectively.
Pass-through inputs, and the video output, support RGB and component video formats.
The pass-through input format must be compatible with the display input.
The appropriate cabling for the pass-through input, and video output, will vary depending
on the home theater configuration. If the pass-through source, or display, uses a VGA
connector, use a VGA to BNC “breakout” cable. If they use BNC connectors, use 75-
ohm video cables that have 75-ohm BNC-male connectors at both ends.

Rack Mounting
For installation in a 19” rack, remove the two case screws on the left and right sides of
the unit. Place a rack-mount adaptor on each side and loosely replace screws through the
rack-mount adaptors and case cover. Align the rack-mount adaptor front tabs so that their
front edge is flush with the backside of the front panel and so they are vertically aligned
with the front panel. Retighten the screws.
It is suggested that a 1U space be left above and below the VisionPro for better cooling.

Basic Setup −Step By Step
The remote control setup sequence for common configurations is described below. For
additional information, see the Installation Commands section.
•Connect video cables and power. Turn all required components on.
•Set the output type. Use RGBHV (default) if display has an RGBHV input. Examples:
YPRPBtrilevel: MENU 11OK Component with embedded trilevel sync
YPRPBbilevel: MENU 11OK Component with embedded bilevel sync
RGB H−V−: MENU 12OK RGB with discrete H−and V−sync (default)
RGB S−: MENU 13OK RGB with discrete composite−sync
(default)
RGsB: MENU 14OK RGB with embedded bilevel sync
•Set the output resolution. For a fixed pixel device use the maximum resolution it
accepts, not its native resolution. This will improve the picture unless there is a major
design flaw in the fixed pixel display. The commands are as follows:
480p: MENU 21540p: MENU 22600p: MENU 23
720p: MENU 24768p: MENU 25840p: MENU 26
1080p: MENU 271080i: MENU 28
Other: MENU 3value OK, where value is the resolution (e.g. 9, 0, 0)
•Set the vertical refresh rate (default = 59.94 Hz). For NTSC, use the default. For PAL,
using 50.00 Hz is optimal, but higher rates can be used to reduce flicker. Press
“MENU 4value OK ” where “value ” is the vertical refresh rate in hundredths. For
example a vertical refresh rate of 59.94 is entered as MENU 45 9 9 4 OK.
•Set the output aspect ratio. Press “MENU 6value OK ” where “value ” is the desired
screen aspect ratio in hundredths (16:9 is MENU 6178, 4:3 is MENU 6133)
•For MENU commands press the MENU button, use arrow keys to highlight the next
item in the list and press the OK button. An “→”denotes levels in the menu hierarchy.
•Set input types (Select input then MENU →IN →TYPE →(VID, SVID, YPRPB, PASS),
OK)
•Play a DVD calibration disc and select it as the input source. Typically either AVIA™
or Digital Video Essentials™ calibration DVDs are used.
•Display one of the test images with “overscan” markers. On AVIA one such test pattern
is the 200 TVL chart in the Advanced AVIA section. Select the appropriate input
aspect ratio so the test pattern is full-screen (e.g. 16:9 for a 16:9 screen aspect ratio).
•Adjust output size and position to minimize the amount of overscan. In other words, try
to get the entire active image on-screen. If the display has output size and position, use
it rather than the Lumagen controls. Otherwise use the following Lumagen commands:
For sizing: MENU →OUT →RES →SIZE →[, , , ], OK
For positioning: MENU →OUT →RES →POS →[, , , ], OK

Vision Pro™User Manual and Installer Guide
© 2003 Lumagen, Inc. 11 Rev 1.13
•Adjust the input size and position using the Lumagen controls. When the Lumagen
input size controls are selected, the corner of the image being adjusted is moved toward
the center of the screen to simplify accurate calibration. First adjust the top-left of the
image so that all active pixels are on-screen. Then adjust the bottom-right.
For top-left: MENU →IN →ADJ →SIZE →TOPL →[, , , ], OK
For bottom-right: MENU →IN →ADJ →SIZE →BTMR →[, , , ], OK
•Recheck the output size and position and readjust as necessary.
•Set the output black pedestal. This specifies if output blank and black are the same (0
IRE), or if blank is a lower level than black (7.5 IRE). Typically this should be set to 0
IRE for fixed-pixel displays, and 7.5 IRE for CRT based displays. The command is:
For 0 IRE: MENU →OUT →LEVL →PDSTL→0 IRE, OK
For 7.5 IRE: MENU →OUT →LEVL →PDSTL →7.5 IRE, OK
•Set the input black pedestal. This specifies if input blank and black are the same (0
IRE), or if black is a higher level than blank (7.5 IRE). Typically this should be set to 0
IRE for component inputs, and to 7.5 IRE for composite and SVideo, but this is not
always the case. If uncertain, 0 IRE is the safest selection. The command is:
For 0 IRE: MENU →IN →ADJ →PDSTL →0 IRE, OK
For 7.5 IRE: MENU →IN →ADJ →PDSTL →7.5 IRE, OK
•Set the black level. Use the AVIA “PLUGE” which has vertical bars moving left and
right for 2 and 4 IRE (black is 0 IRE) and at 96 and 98 IRE (white is 100 IRE). For
calibrating black, look at the 2 and 4 IRE bars and adjust so the 4 IRE bar is visible and
the 2 IRE bar is barely visible. Note for many displays the black level will not be
constant between dark and light scenes, so some compromise may be needed. If the
display has a black level control (also called “brightness”), use it for the DVD input,
then use the Lumagen controls for differences in other inputs. The command is:
MENU →IN →COLR →BLCK →[,], OK
•Set the white level. Use the AVIA PLUGE pattern. For calibrating white, look at the 96
and 98 IRE bars and adjust so the 96 IRE bar is visible and the 98 IRE bar is barely
visible against white. If the display has a contrast level control, use it for the DVD
input, then use the Lumagen controls for differences in other inputs. The command is:
MENU →IN →COLR →CONT →[,], OK
•Set Color and Hue using the Lumagen controls. Use the Advanced AVIA color test
pattern. Follow instructions on the AVIA disc for using the blue filter and the color bars
for use with the blue filter.
For color: MENU →IN →COLR →COLR →[, , , ], OK
For bottom-right: MENU →IN →COLR →HUE →[, , , ], OK
•Set Y/C Delay (formerly called CPHASE). One pattern to use is the Y/C-Delay pattern
in the Special Test section of Advanced AVIA. On the right half of the image there are
red and yellow vertical bars. Adjust the yellow-red transitions to minimize any black.
MENU →IN →ADJ →YC-DLY →[, ], OK
•The grayscale “color-of-gray” should be calibrated by a video technician. Have them
contact Lumagen for the service codes to access the five-point color of gray calibration.

Vision Pro™User Manual and Installer Guide
© 2003 Lumagen, Inc. 12 Rev 1.13
•Copy the DVD configuration to all configuration memories (MENU →IN →COPY →
OK).
•Calibrate other inputs, if desired.
•Name the inputs, if desired (MENU →IN →NAME →OK and follow directions).
•Set power-on message, if desired (MENU →MISC →POWR →MSG →[, , , ], OK)
•Lock the configuration, if desired (MENU →MISC →LOCK →LOCKED, OK)
•Save the configuration (MENU →SAVE →SAVE, OK)

Hints For Optimal Picture Quality
•Proper calibration, along with the use of high-quality cables, is as important for
attaining the best picture as are deinterlacing and scaling. If you don’t have one,
purchase a DVD setup disc, such as AVIA™, or Digital Video Essentials™ and watch
the training lessons provided.
•If possible, use a power conditioner for the video source, video processor and the
display. Power line noise is at least as important an issue for video as it is for audio.
•For fixed-pixel devices, use RGBHV from the Lumagen to drive BNC inputs, when
available, to minimize noise. For RGB, “Luma noise” is distributed across the red,
green and blue channels but for component, Luma noise is all on the Y (Luma) channel.
So, RGB sources can show lower noise levels since the weighting of the three channels
for “Luma” as perceived by the viewer tends to filter out some of the Luma noise.
•Contrary to popular opinion, most fixed-pixel displays look best running their input at a
resolution higher than their native resolution, such as 1024p, and in some cases 1080i,
for a 720p or 768p display. This is because the process of “down-sampling” the higher
resolution to the display’s native resolution can filter out some of the noise and provide
more detail. Note: Rules for display of Video are completely different than for the
display of PC data. For display of PC generated data, such as spreadsheets, the PC
resolution should be set to match the native resolution of the display.
•Avoid running video signals through the video switch inside receivers, as these tend to
degrade video quality. The rule of thumb for a video switch is to have 10 times the
bandwidth of the video being switched. This equates to 70 MHz for SDTV and 300
MHz for HDTV switching.
•Component inputs on some RPTVs and projectors do not work with standard width
HSync pulses. When using component video to drive the display, if there is a “green
cast” the likely cause is a design problem in the circuitry inside the display. Changing
to bilevel sync, and/or making the HSync pulse narrower with the Lumagen HSync
Width command (MENU 0940) can help eliminate this problem.
•A system’s “ground loop noise” can cause problems. This shows as a screen-width
horizontal-band of intensity variation. Since the Lumagen case “floats” it may need to
be grounded to the video source and/or display.
•Component DVD sources provide the best standard-definition picture quality, but
SVideo sources are often a bigger challenge and therefore can show more improvement
using Lumagen. Since many satellite receivers, and other video sources, only have
composite and SVideo outputs, this improved SVideo performance is important for
many installations.
•Memory A (MEMA) and memory B (MEMB) can be used to have two independent
configurations, such as for day (bright room) and night (dark room). One difference for
this example is that the black level will be set higher for daylight viewing than for
viewing in a darkened room. To program MEMB to be different, first setup MEMA
normally, use the input copy command to copy to MEMB, than adjust MEMB as
desired. Remember to save changes.

Command Format
VisionPro commands are selected with the supplied infrared remote, or the RS232 serial
port. To prevent possible command conflict, only one of these inputs should be used at a
time.
The infrared remote control command notation is described below:
•Remote buttons are named as shown on the remote in a bold font.
Example: MENU.
•For comma separated lists, press the buttons in the sequence shown.
Example: For the list RGBHV, OK, press RGBHV then OK.
•For parenthesized lists, select one button from the list.
•For square-bracketed lists, press as needed.
Example: For the list [, , , ], press the arrow keys as needed.
•For menu commands press the MENU button. The , and arrow keys are used to
select the function. The arrow key is used to enter sub-menus. This is shown as:
MENU →MenuItem →MenuItem.
•Numerical entries are listed as value. While entering the value, the arrow key acts as
a backspace key.
•Some commands are activated immediately. Other commands must be explicitly
accepted by pressing OK. If needed, OK is listed as part of the command.
•Pressing EXIT cancels a partially completed command. If the menu system is active,
EXIT returns to one level higher in the menu system.
•There are two independent configuration memory types for each input (MEMA, and
MEMB). The input setup and output resolution/timing can be set independently for
each memory. Note that, initially, there is a single output mode for all configuration
memories. To program an input memory, first select the input, then press the
appropriate configuration memory button, and use the menu system to configure.
•Some menu commands are only available when their respective input is selected.
Example: Calibration commands, such as contrast, are not available when the pass-
through input is selected.
•Before changes are saved, they can be discarded by entering standby mode.
•Save the configuration after making changes, or they will be lost when entering STBY
mode.
•To prevent unintended configuration modifications, after saving, use the lock
command.
If the serial port is used, the ASCII character associated with the respective remote
control button must be sent. See the Serial Interface section for information on serial
commands.

Installation Commands
See the Command Format section for a description of the installation command interface.
Display Setup
The factory-default video output is set to RGBHV with negative sync, 480p, 60-Hertz
vertical-refresh-rate, and a 1.78 (16:9) screen aspect-ratio.
The factory-default mode is for all configuration memories to use a single output setup.
Alternately, independent output settings can be selected (see Multiple Output Settings).
Display Type
Select the video output color-space and synchronization type. The selection takes effect
immediately. The arrow keys are then active and have immediate effect. Press the OK
key when done to prevent the arrow keys from continuing to change the sync type.
RGBHV: MENU, 1, 2, [,], [, ], OK
sets both H and V sync as negative (default)
sets both H and V sync as positive.
sets negative H sync. If needed, select after the or key.
sets positive H sync. If needed, select after the or key.
RGBS: MENU, 1, 3, [,], OK
sets negative composite sync (default)
sets positive composite sync
RGsB: MENU, 1, 4, [,], OK
sets embedded bilevel sync
sets embedded trilevel sync (default)
YPRPB: MENU, 1, 1, [,], OK
sets embedded bilevel sync
sets embedded trilevel sync (default)
Default: The respective default is selected if no arrow key is pressed.
Vertical Resolution -Presets
Set the output active vertical resolution to one of eight preset values. See the Selecting the
Output Resolution section for more information. This command maintains the current
display type, aspect ratio, and vertical refresh rate. The only interlaced format supported
is 1080i at 60, or 50, Hertz. The command format for each resolution is:
480p: MENU, 2, 1, OK 540p: MENU, 2, 2, OK 600p:
MENU, 2, 3, OK
720p:MENU, 2, 4, OK 768p: MENU, 2, 5, OK 840p:
MENU, 2, 6, OK
1080p: MENU, 2, 7, OK 1080i: MENU, 2, 8, OK

Vertical Resolution -Programmable
This command allows the output active vertical resolution to be set from 480p to 1080p,
in scanline increments. See the Selecting the Output Resolution section for more
information. This command maintains the current display type, aspect ratio, and vertical
refresh rate. Out of range values are ignored. The command format is:
MENU, 3, value, OK
or MENU →OUT →RES →VRES →value, OK
Vertical Refresh Rate
Set the output vertical refresh rate in the range of 48, to 75, Hertz (entered in hundredths
as 4,8,0,0to 7,5,0,0). See the Selecting the Output Resolution section for more
information. This command maintains the current display type, aspect ratio and vertical
active resolution. The display must support the vertical resolution and vertical rate
specified. Out-of-range values are ignored. The command format is:
MENU, 4, value, OK
or MENU →OUT →RES →VRATE →value, OK
Horizontal Refresh Rate Note:
Do not use this command unless the display requires a rate different than
the interpolated rate and the correct horizontal refresh rate is known.
Set the horizontal refresh rate in Hertz. The vertical total scanline count is adjusted to
achieve the specified horizontal frequency, if possible. The active vertical resolution is
not changed. Out-of-range values are ignored. The command format is:
MENU, 5,value, OK
or MENU →OUT →RES →HRATE →value, OK
Horizontal Sync Pulse Width
Some displays require a narrower horizontal sync pulse than standard SMPTE timing.
This command allows the HSync pulse width to be controlled. The command format is:
MENU, 0, 9, 4, 0→[, ], OK
Output Size Note:
Generally, this command should not be used. Instead use the display’s size controls.
Change the percentage of the scanlines that contain active video, and the percentage of
each scanline that contains active video. Only the active times are changed. The vertical
total-scanline-count and horizontal total-pixel-count are not changed. An example use for
this command is to match fixed display timing requirements. This command can also be
used to match the pass-through input timing.

Vision Pro™User Manual and Installer Guide
© 2003 Lumagen, Inc. 17 Rev 1.13
The command format is:
MENU →OUT →RES →SIZE →[, , , ], OK
Output Position Note:
Generally, this command should not be used. Instead use the display’s position controls.
Reposition the active display.An example use for this command is to match fixed display
timing requirements. This command can also be used to match the pass-through input
timing.
The command format is:
MENU →OUT →RES →POS →[, , , ], OK
Aspect Ratio.
Select the screen aspect ratio. The screen aspect ratio range is 1.33 (4:3) to 2.35 and is
entered in units of hundredths (e.g. 2.35 is entered as 2, 3, 5). See the Selecting the
Output Resolution section for more information.
The command format is:
MENU, 6,value, OK
or MENU →OUT →ASPECT →value, OK
Graybar Intensity Note:
Consult a home theater specialist for assistance setting the graybar intensity.
Some displays have significant burn-in issues (e.g. CRT and Plasma), while others do not
(e.g. DLP). Some degree of burn-in will occur on any susceptible display, but this
command can help minimize it by allowing the intensity of graybars to be adjusted.
The command format is:
MENU →OUT →GBAR →SIDE →[, ], OK
Output Black Pedestal
This command specifies if there is an output black pedestal. The default is 0 IRE, but
some projectors require the 7.5 IRE setting. The command format is:
MENU →OUT →LEVL →PDSTL →(7.5 IRE, 0 IRE), OK
Output Mode
When set to factory-defaults, changes to the output settings affect all configuration
memories. It is possible to have independent output settings for each configuration
memory by setting the output to independent mode (INDEP).
Some source devices can dynamically switch their output type between NSTC, PAL and
SECAM. To allow precise calibration for these formats, two additional output modes
(AUTOA/B and AUTOINDEP) are provided, and are similar to the SAME and INDEP modes,
