2.1. Air Flow and Maintenance Clearances
The HJT Model 100 Projector should be placed in a location where it is easily accessible
on both right and left sides. The area should be well ventilated, and the projector air
intakes and exhausts should not be blocked in any way.
2.1.1. Air Flow
The HJT Model 100 Projector dissipates 4,100 BTUs/hr and must not be placed in an
enclosure that would limit air flow. Adequate ventilation is necessary to provide proper air
flow to prevent overheating. For optimum operation, maintain the following air flow
clearances around the projector for proper heat venting.
The HJT Model 100 Projector should be placed in a location where it is easily accessible
on both sides. The area should be well ventilated and the air intakes and exhausts
should not be blocked in any way. For best operation, refer to
Table 2.0-1 for the recommended clearances around the projector.

2.4. Projector-to-Screen Distance and Alignment
Set the projector to the proper distance from the screen as determined by the
screen width and lens ratio illustration (refer to Figure 2.0-7 on page 2-7).
The Lens Pattern illustrated in Figure 2.0-8 on page 2-8 will help determine the
optimal screen widths and throw distances for the zoom lens.
The maximum projector-to-screen vertical tilt angle for a table or ceiling mount is
15º vertical. Any tilt greater than 15º will result in a severe keystone error that
cannot be corrected by the Keystone adjustment.
The HJT Model 100 Projector can be used upright or downright at any angle
from 5° to 85°.
Figure 2.0-5 Maximum Projector-to-Screen Vertical Tilt Angle

2.5. Lens Throw Distance and Screen Width
The distance from the closest point of the screen to the projector is known
as the throw distance.
Table 2.0-3 Lens Definitions
Phrase
Throw distance Distance from the projector lens to the closest point on the screen.
Screen width
Maximum width of picture that can be displayed.
Definition
To determine the throw distance from the projector to the screen, multiply the
screen width by the lens ratio.
For instance, if the projection lens being used is the 1.5:1 lens and the desired
screen width is 3.65 meters (12 feet), the distance from the closest point of the
screen to the projector lens is 5.48 meters (18 feet), as illustrated in Table 2.0-4.

The HJT Model 100 Projector can be controlled by the Executive IR remote, the
Technician IR remote or a computer. One of these IR remote controllers is supplied with
the projector. Both remotes perform the same functions when operated through the
menu tree. This chapter assumes the projector is being operated using the Executive
Remote control.
3.1. Executive Remote
The Executive Remote Control can be used as an infrared or tethered remote
(see Figure 3.0-1 on page 3-2). If using the Executive remote as an IR, do not
plug in the tether cable. If using with the tether, plug one end of the 8 meter tether
cable into the remote and the other end into the phone jack (see Figure 3-8) on
the projector’s rear panel. One (1) end of the tether cable is terminated in a phone
jack and the other end has a telephone jack. The IR function is disabled when the
tether cable is plugged into the remote. All setup, image, and raster adjustments
are made with the Executive Remote by navigating through the menu tree (refer
to Menu Structure Diagram, Figure 3.0-3 on page 3-11).
The Executive Remote has a maximum range of about 16 meters (line of sight
only) when using the IR transmitter. It does not transmit effectively through a
rear-screen window.

3.2. Technician Remote
The Technician Remote provides quicker access to some functions by using keys
on the remote. In the Menu Structure Diagram (Figure 3.0-3 on page 3-11), these
direct access functions are indicated by a symbol after the function name. Direct
access features eliminate the need to access functions via the menu structure
and save time during set up.
The Technician Remote can be used as an IR remote or with a tether like the
Standard Remote. An 8 meter tether cable is provided with the Technician
Remote. Inserting the tether cable disables the IR transmitter. See Figure 3.0-2
on page 3-4 for an illustration of the Technician Remote control keys and Table
3.0-1 on page 3-5 for key function and usage.

3.7. Full Menu Structure
To view the MAIN MENU, press MENU on the remote. The MAIN MENU displays on
the screen.
NOTE: If another menu is displayed, press ESCAPE repeatedly until the MAIN
MENU appears.
Menu screens remain active for approximately 60 seconds, then the menu "times
out" and is cleared from the screen. To issue a command, press MENU and the
number of your selection.
Figure 3.0-3 on page 3-11 shows the MAIN MENU Structure and the submenus.
For a description of each menu item see Section 3.11 on page 3-17.
After becoming familiar with navigating the menu, the next step is to select a
channel. This is explained in Section 3.8 on page 3-12. Be sure that the channel
selected has a source file set up to handle the type of graphic source to be
viewed. Observe the list of sources on the selected channel to confirm this. Refer
to 3.9 on page 3-14 for information on attaching a source. See Table 3.0-6 for
definitions of terms.
Table 3.0-6 Channel and Source Definitions
Term
Definition
An Autoselect group of up to 20 source files, using one (1) specific
VIC/switch number, set up to accept up to 20 sources with
different parameters such as horizontal and vertical scanning
rates, interlaced/noninterlaced scanning, ± sync levels.
A channel defines the input path for a source.
Channel
A specific input format such as VGA, HDTV, NTSC etc. with a given
set of parameters such as horizontal and vertical scanning rates,
interlaced/noninterlaced scanning, and sync source/polarity.
Source
Data set in the projector’s memory created to handle a specific
video source. Source files must be set up to match the specific
geometric and convergence parameters in the incoming source.
Source File
If there is no source file on the selected channel to handle the source to be
viewed, the proper source file can be attached from the source list to the selected
channel. Refer to Section 3.9 on page 3-14 for procedures for attaching a source.
If there is no acceptable source file set up on any other channel to attach to the
selected channel, a source file must be created (set up) to handle the source to
be viewed. Procedures for setting up source files are covered in Chapter 4.
3.8. Selecting a Channel
A channel is an Autoselect group of up to twenty (20) source files set up to
receive different video sources within any one (1) VIC slot or port.
3-12
Hughes-JVC Technology Corporation
Download from Www.Somanuals.com. All Manuals Search And Download.
Chapter 3—Operation
NOTE: The Autoselect feature means that when the incoming source changes in
the active channel, the projector automatically selects and switches to the source
file within that channel that most closely matches the incoming source's
parameters. The channel selected must have a source file set up to handle the
type of incoming video or graphic source. The terms “source” and “source file” are
often used interchangeably (refer to Table 3.0-6 for definitions).
The procedures in Chapter 4 are for setting up a new source file for a new
source. The resultant geometric and convergence data in the new source file can
then be "attached" to different channels (refer to Section 3.9). The Geometry and
Convergence settings on these attached sources must be adjusted with care—
adjustments made on attached sources will alter the data for all channels
attached to the source file. Note that the setup data is being shared by all
channels attached to the source file by the attached source from the original
source file.
To select a Channel from the Menu System :
1. Press MENU to display the MAIN MENU.
2. Press #2, CHANNELS from the MAIN MENU.
3. Enter channel number using the number keys.
4. Press ENTER once to highlight the selected channel. Press ENTER again to
activate the highlighted channel. If using arrow keys, scroll to highlight the
desired channel and press ENTER once.
5. If the active channel contains more than one (1) source file for the incoming
video source, the closest match will be automatically selected.
NOTE: If the channel number is known, it may be selected by pressing the
channel number, then pressing ENTER.
3.8.1. Active Channel
Press ENTER with no numbers preceding it, and the active channel
number will display on the screen for three (3) seconds, provided the
ONSCRN display mode is ON.
In the CHANNELS MENU the active channel is shown with a pointer to the
left of the number (as long as the active channel number is on the
screen list).
NOTE: Do not confuse the active channel with the highlighted channel.
The active channel is the channel that is on screen. The highlighted
channel is the channel that has been scrolled to with the arrow keys or
selected by pressing its number and ENTER, but has not yet been made
active by pressing ENTER again.
Pressing the channel number and ENTER “highlights” the channel on the
CHANNELS list. Pressing ENTER again makes it “active” (on screen).
Sources may be attached (see Section 3.9) to the highlighted channel,
while another channel is active.
The active channel is displayed in the upper right corner of the
CHANNELS MENU. See Figure 3.0-4 for an illustration of the CHANNELS
MENU and active/highlighted channels.

3.9. Attaching a Source
A source is defined as an input signal with a specific set of parameters such as
horizontal/vertical scan rates, interlaced or noninterlaced scanning, and sync
type/polarity. An incoming source can be attached to a source file that was
previously set up for a different source. The attached source is using the setup
data from the original source file.
NOTE: Setup procedures for new sources are covered beginning with
Section 4.1. on page 4-2. When setting up a source file for a new source,
the operator:
1. Connects the source to the side panel input jacks;
2. Selects the channel to receive that source;
3. Names the channel to show the source type;
4. Selects the VIC slot and/or VIC port to handle that source (if the projector
uses an optional or a multi-port VIC);
5. Follows the adjustment procedures in Chapter 4 on page 4-37
to set up a source file to handle that specific source.
Once a source has been set up, it can be “attached” to another channel.
To “attach a source” means that an original source file and its geometry and
convergence parameters are being used by another source input signal.

Chapter 3—Operation
The attached sources are using the same source files (they are the same source
files—not copies).
A source can be attached to a source file from a different channel. Geometry and
convergence settings must not be adjusted on attached sources because all
attached sources will then be altered by the same adjustment. This is only true for
geometry, convergence and ILA® settings. Timing and picture settings come into
the attached source at the default levels and may be adjusted without affecting
the original source or any other attached source.
Two (2) identical sources can be located in two (2) different channels with two (2)
distinctly different picture settings for use with possibly different room
environments. For example, different brightness and contrast settings could be
used for the same source in two (2) different channels, saving the time of
repeatedly adjusting contrast and brightness.
NOTE: One channels’ source file parameters can be copied and used as starting
points to set up new sources in other channels. The first channel may be copied
to a second channel. Follow the procedure in Section 4.10 on page 4-38 about
Backing up Settings. The channel (groups of source files) can be customized to
suit whatever purposes are needed.
Each channel is capable of handling up to 20 different sources. There are 99
channels (groups of source files) available. The maximum number of
channel/source combinations is 200.
To attach a source to a channel:
1. Press MENU to display the MAIN MENU.
2. From the MAIN MENU select CHANNELS.
3. From the CHANNELS list, press the number of the channel to attach the source
to. If the channel is not highlighted press ENTER to highlight the channel.
Do not press ENTER if the channel is already highlighted (this would make the
channel “active”).
4. Press the right arrow key to move to the SOURCES list.
5. Use the arrow keys and scroll to highlight the source desired.
6. Press ENTER to attach the highlighted source to the channel that is
highlighted in the CHANNELS list.
Do not make any adjustments to geometry
or convergence on these “attached” sources. Any adjustments will also
CAUTION!!!
alter the original source file data and other attached sources.

This chapter assumes the operator is using a remote control and accessing setup
functions through the menu tree. All instructions are given with reference to using the
menu tree for setup functions. If using a PC or laptop computer to control the projector
refer to Table 3.0-10 on page 3-23 for the equivalent key functions.
Chapter 3 covered mainly operation for projectors that are already positioned, set up,
and ready for operation. This chapter covers the complete projector setup procedures.
Prior to starting the procedures in this chapter, the operator should review Chapter 3 to
become familiar with navigating the menu and using the remote control keys.
Prior to performing any adjustments, allow the projector to warm up for at least 60 minutes.
4.1. Setup Preparation
In the Timing and Geometric adjustments below, Green is the active and
on-screen color. Red and Blue are hidden because they track on Green.
When the Timing and Geometric adjustments in this section are finished,
Red and Blue is then centered to match Green and converged onto Green in the
Convergence procedures. To hide Red and Blue, toggle the RGB key to RED,
press HIDE, then toggle to BLUE and press HIDE. Green is now the only color
displayed on the screen. Toggle the RGB KEY to highlight G.
To avoid redundancy in the procedures in this chapter, some general information,
instructions, phrases, and definitions are given below.

Procedures
General Information
Verify that ONSCRN key is toggled to ON if the screen does not show
the window or menu correctly.
When performing ILA® SENSITIVITY AND BIAS, BLACK LEVEL (G2),
SENSITIVITY OFFSET, and UNIFORMITY (SHADING), verify that the
SHUTTERS ON HIDE box under the SYSTEM-PREFERENCES menu is
checked. Checking this box activates the shutter mechanism to
hide the ILA® images and provides easier, more accurate settings
of these adjustments.
On single-axis adjustments such as PICTURE SETTINGS, G2,
THRESHOLD, SENSITIVITY, ILA® BIAS etc. up/down arrow keys are
shown on the screen—left/right arrow keys, though not shown, will
also accomplish the same adjustments.
After completing the timing, geometric, and convergence adjustments for one (1)
source, the adjustment data may be backed up by copying the channel to another
of the 99 channels and the source file to another of the 20 sources.
NOTE: When backing up a channel, ensure that the “copied to” channel is blank.
Channel paste is only allowed to “cut” empty channel. Source paste will overwrite
current source geometry, convergence and ILA® settings. All data will be deleted
on the “copied to” channel. Refer to the Backing up Settings function from Section
4.10 on page 4-38 for more detail.
This provides backup for a previously set up channel and a good starting point for
setting up other channels. Also ensure that the "copied to" channel uses the
same type of VIC as the "copied from" channel. If the projector uses only one (1)
VIC, this is not applicable.

Chapter 4—Setup Adjustments
If the projector uses more than one (1) type of VIC, the type can be determined
by accessing the SYSTEM-MAINTENANCE menu and selecting STATUS LIST. Each
VIC slot will be displayed with the type of VIC in each slot. Complete the Timing
section first, Geometry next, and Convergence last.
They are performed in this order because Geometry depends on proper Timing
settings and Convergence depends on correct Geometry.
Ensure that the projector is installed and positioned correctly at the outset so that
all later adjustments will be at their optimal levels and the image will be the
sharpest possible. Positioning the projector is the most important step in the
setup procedures. The projector-to-screen alignment should be as square as
possible before starting setup procedures in order to accomplish Timing,
Geometric, and Convergence adjustments properly.
Prior to starting the procedures, a channel and source (source file) must be
selected for the setup adjustments. This is covered in Section 4.1.2 on page 4-6.
A rough focus of the projection lens may be necessary to be able to read the
menus.
4.1.1. Projection Lens Focus (Rough)
For the Timing and Geometry setup procedures below, it is necessary to
obtain a rough focus of the Projection Lens in order to read menus and
do the adjustments. If the focus is adequate to read the menus, this
procedure can be skipped until after the Timing and Geometry
adjustments are finished. When the Timing and Geometry adjustments
are complete, and prior to starting convergence, the Projection Lens
focus adjustment should be repeated and a sharp focus obtained.
To obtain a Rough Focus of the Projection Lens:
1. Press MENU to display the MAIN MENU on the screen.
If necessary, use the ESCAPE key to back out to the MAIN MENU.
2. Select SYSTEM from the MAIN MENU.
3. Select TEST PATTERN from the SYSTEM menu.
4. Select FOCUS from the TEST PATTERN menu.
NOTE: The H pattern is preferred for focusing the Projection Lens.
5. Select PROJECTION LENS from the SYSTEM menu.
6. A small window displaying FOCUS and ZOOM arrows appears on the
screen.
7. Use the up/down arrow keys to zoom the image to the desired size.
The raster and image should be smaller than the screen. Ensure the
FOCUS ENABLE box in the PREFERENCES menu is checked.
8. Use the right/left arrow keys to get a rough overall focus to be able to
read menus. A sharper focus will be obtained later after the Geometry
procedures are completed.
9. Press ENTER to complete this adjustment.
10. Press ESCAPE twice to display the MAIN MENU.

4.1.2. Editing Channels, Sources, and VICs
Select CHANNEL and SOURCE files from the CHANNELS and SOURCES lists
(see Section 3.8 on page 3-12). Edit the CHANNELS’ and SOURCES lists to
select a name for the new channel, VIC, and source. Figure 4.0-1and
Figure 4.0-2 illustrate the CHANNELS and SOURCES’ lists showing “active”
and “highlighted” channels and sources. Verify that the projector is
receiving the appropriate source.
If the active channel receives a source that
CAUTION!!!
does not have an exact match in a source file, the projector will match the
source to the source file that is closest to the new source parameters. If
adjustments are attempted, the following statement appears on the
screen: “Adjustments are inhibited on an approximate match.” The
projector will not allow adjustments to a source file that has been set up
for one source and is only being used now as an approximate match for
the new source. If allowed, the adjustments would corrupt the data in the
current source.
To edit a Channel and Source (refer to Figure 4.0-1):
1. Select CHANNELS from the MAIN MENU.
2. From the CHANNELS list, select a new channel number by pressing the
channel number, and ENTER. This highlights the channel for editing
purposes but does not make it active. The channel can also be
highlighted with the arrow keys.
3. Press MODE. This brings up a submenu for editing (this is a toggle
key. Pressing MODE again removes the submenu).
4. Use the up/down arrow keys to select EDIT and press ENTER.
5. The NAME field should be highlighted. If not, use the left/right arrow
keys to highlight the NAME field.
6. Press ENTER to edit the NAME field.
7. Use the up/down arrows to move the characters in the first letter of
the NAME FIELD. When the desired letter/number is shown, press the
right arrow key. This enters the selection and moves to the next
column.
8. Select the next letter/number in the same manner as in the
preceeding step. Repeat the prior two (2) steps for the remainder of
the columns. When complete, press ENTER.
9. When the channel name is complete, press the right arrow to move to
the VIC column.
10. In the VIC column, press ENTER, and then edit the VIC number. Use
the up/down arrow to choose a VIC. If no optional VICs are used, the
default is 1.1. Press ENTER to accept the VIC number. If an optional
VIC is used, the first number is edited to 2. The second number is
edited according to the type of VIC used.

4.1.3. Factory-Preset Channels and Sources
Some channels have factory-preset source files, which the operator can
select one (1) of for faster setup. These preset source files should be
checked for proper timing, geometry, and convergence and readjusted, if
necessary. The following table indicates the factory-preset sources
attached to Channel 1:

Chapter 4—Setup Adjustments
4.1.4. Internal Source
Every channel has a preset internal source shown as SOURCE 0 on the
SOURCE list. This is factory set “default timing” for the projector with
scanning rates of 33.3 kHz (horizontal) and 59.3 Hz (vertical). This
internal source is used to read menus when there is no source input
connected to the projector. To use this internal source, select CHANNEL 0,
then press ENTER. This internal source can be copied to any other
channel but it cannot be cut, edited, or pasted to.
4.2. Timing Settings and Adjustments
Each type of source requires timing settings and adjustments. Perform these prior
to geometry because the geometry adjustments are dependent on the proper
timing of raster scanning. The Timing adjustments are universal to RGB and color
selection is not necessary.
4.2.1. Clamp Type
Use the default clamp type unless there are sync problems with the new
signals being used.
Clamp type sets the type of clamping used with the sync pulse.
There are three (3) types of clamping;
BP (Back Porch) is used in 95% of all computer and video inputs,
Back Porch is the default;
ST (Sync Tip) is seldom used but is necessary when there is
no Back Porch to clamp on;
TL (Tri-Level) which is used mainly for HDTV.
To set the Clamp Type:
1. Access the TIMING menu.
2. Press #4, CLAMP TYPE from the TIMING menu.
3. Highlight BP, ST, or TL using arrow keys.
4. Press ENTER to select.
NOTE: WVHS and HDTV use tri-level sync signals. When the HDTV
VIC is used, the clamp type should be “Tri-level.”
4.2.2. VTR Mode
Set VTR mode to ON position if the projector’s input comes from a VTR
source or is line-doubled DVD. This setting stabilizes the VTR sync input.
Otherwise, set the VTR mode to OFF.
To set the VTR Mode:
1. Select VTR MODE from the TIMING menu.
2. Press ENTER to toggle the VTR MODE to OFF (unchecked box)
unless using a VTR as a video source.
3. Press ESCAPE to return to the TIMING menu.

4.2.3. Blanking
Use Blanking to mask out unwanted anomalies on the picture’s edges.
An unblanked image allows the entire image to be displayed on the
screen. If Blanking is adjusted incorrectly, the raster may “blank out” at
the right or left edges of the image. Adjust Blanking to the edge of the
active image.
To adjust Blanking:
1. Select TEST PATTERN #1, EXTERNAL IMAGE, from the TEST PATTERN
menu.
2. Select the BRIGHTNESS ADJUSTMENT from the PICTURE menu.
3. Use the arrow keys to increase the brightness level to view the entire
raster and video (refer to Figure 4.0-3 on page 4-12). Press ESCAPE
when finished.
4. Select T/L (top/left) BLANKING, from the TIMING menu.
5. Verify that the image and raster are smaller than the screen (refer to
Figure 4.0-3). If not, access the SIZE ADJUSTMENT from the
GEOMETRY menu and use the arrow keys to size the video image just
smaller than the screen size. Press ESCAPE or ENTER when finished.
6. Use the arrow keys to move the masking toward or away from the top
and left edges of the screen. When finished press ENTER or ESCAPE
7. Select B/R (bottom/right) BLANKING from the TIMING menu.
8. Use the arrow keys to move the masking toward or away from the
bottom and right edges of the screen.
9. Press ENTER or ESCAPE to exit the adjustment.
NOTE: Blanking, Phase, Size, and Centering are functions that
contribute to the entire image. If one (1) function is adjusted,
the others need to be rechecked and readjusted, if necessary.
4.2.4. Phase
The Phase adjustment positions the image within the raster.
To adjust Phase:
1. Use external image.
2. Select PHASE from the TIMING menu.
3. Use the arrow keys and adjust the horizontal and vertical phase so
that the image folds over on either side or at the top and bottom.
Center the image on the raster (see Figure 4.0-3 on page 4-12).
NOTE: Overadjusting vertical phase may cause vertical retrace lines
to appear in the image.
4. Press ESCAPE or ENTER to exit this adjustment.
5. Recheck the BLANKING ADJUSTMENT.

4.3. Geometric Adjustments
Geometric adjustments are performed for each type of source. Timing settings
must be completed before geometry can be performed correctly.
NOTE: Toggle the REG ENABLE box to the unchecked mode in the GEOMETRY
menu. This ensures that any previous convergence corrections will not influence
the Geometry adjustments
4.3.1. Centering (G)
Centering moves the position of the raster on the CRT without wrapping
around.
To Center (Green):
1. Use an external image.
2. Select CENTERING from the GEOMETRY MENU.
3. Use the HIDE key and hide R and B (toggle the RGB KEY to select R
only and press HIDE then toggle the RGB KEY to select B only and
press HIDE).
4. Toggle the RGB KEY to select G only.
5. Use the arrow keys and position the Green raster vertically and
horizontally so that it is centered on the screen (refer to Figure 4.0-3
on page 4-12).
6. Recheck PHASE and BLANKING and readjust, if necessary.
7. Press ESCAPE or ENTER to exit.
4.3.2. Size
The size adjustment fits the size of the image to the screen size within
the limits of the ILA® and CRT.
To adjust Size:
1. Continue with an external image.
2. Select SIZE from the GEOMETRY MENU.
3. Use the arrow keys and adjust the size of the image to the screen
horizontally and vertically (refer to Figure 4.0-3).
NOTE: Select RGB (all) for coarse SIZE ADJUSTMENT. Select R or B for
fine adjustment of R and B with reference to G.
4. Recheck and readjust centering, phase, and blanking, if necessary, to
keep the entire picture in the center of the screen.
NOTE: Make the picture slightly smaller than the screen size.
This makes other geometric adjustments easier. After completing
geometric adjustments, slightly readjust size, if necessary.
5. Press ESCAPE or ENTER to exit.

4.3.3. Bow
NOTE: Skip this procedure if the vertical centerline is straight and the
horizontal centerline is level (refer to Figure 4.0-5 Bow Distortion on page 4-
14).
With bow distortion, the picture bends in the same direction on the edges
and in the center of the test pattern. This means that the vertical or
horizontal centerline is bowed in one (1) direction causing the entire
pattern to bend in that same direction (refer to Figure 4.0-5 on page 4-
14). Use the Standard Crosshatch test pattern to spot Bow distortion.
To correct for Bow Distortion:
1. Select the Standard Crosshatch test pattern.
2. Select BOW from the GEOMETRY MENU.
3. Use the up/down arrow keys to correct for vertical bow distortion.

4.3.4. Skew/Rotate (G)
Skew and Rotate are corrected in the same procedure using the same
screen patterns. Skew distortion “leans” horizontally like a trapezoidal
pattern. This means the vertical centerline is skewed in one (1) direction
or another causing the entire pattern to lean in the same direction (see
Figure 4.0-7 on page 4-15). Rotation distortion is where the entire pattern
is rotated vertically or horizontally (refer to Figure 4.0-6 on page 4-15).
Use the Standard Crosshatch test pattern (shown in Figure 4.0-4 on
page 4-13) to spot Skew or Rotation distortion. If the vertical centerline is
vertical and the horizontal centerline is horizontal, the Skew setting is
correct (as described in Section 4.3.7 on page 4-18) and should not be
changed.
Perform the Rotate procedure first to make the horizontal lines horizontal.
If the pattern leans left or right (as illustrated in Figure 4.0-7 on page 4-
15) proceed with the Skew procedure to correct.

CRT Focus and H/V Dynamic Focus). This factory-setting does not
normally require readjustment. The FOCUS ENABLE box in the
PREFERENCES MENU may now be unchecked to prevent accidental
defocusing.
4.4. CRT Focus and H/V Dynamic Focus
The CRT and H/V Focus adjustments are factory-set and do not normally require
adjustment. They should be performed together in a back-and-forth manner to
achieve the best possible overall focus.
To perform the CRT Focus:
1. From the FACTORY ADJUSTMENTS MENU, select CRT FOCUS.
2. Select G on the remote.
3. Select the STANDARD CROSSHATCH test pattern.
4. Use the up/down arrow keys to obtain the best possible focus in both the
center of the screen and in the overall test pattern.
5. Repeat the above steps for R and B.
To perform the H/V Dynamic Focus:
1. From the FACTORY ADJUSTMENTS MENU, select H/V DYNAMIC FOCUS.
2. Continue with the STANDARD CROSSHATCH test pattern from above.
NOTE: The H/V Dynamic focus is performed on all three (3) colors together
and the colors are not individually selectable.
3. Use the up/down arrow keys to achieve the best possible focus at the edges
of the screen.
4. Repeat the CRT Focusing from above, then repeat the H/V Dynamic Focus
again. Several iterations may be needed to achieve the best possible overall
screen focus.
4.5. ILA® Sensitivity and Bias
ILA® Sensitivity and Bias are preset for the factory-set sources and will not
normally require adjustment. Readjustments may be required due to variations
between the factory and the field environments. When new sources are set up,
ILA® Sensitivity and Bias must be set (or copied from another source and
touched-up) for each new source.
The ILA® Sensitivity and Bias can be adjusted for any color. It is preferable to
start with Blue since Blue is a weaker color to observe than Red or Green. The
ILA® Sensitivity is the ILA® biasing frequency that affects the resolution and
brightness on the screen. The ILA® bias settings adjust the electrical bias levels
to each ILA® assembly to a “just off” threshold point. The smallest incoming light
from the CRT will cause the ILA® assembly to react. When properly set, this
adjustment will put each ILA® assembly at the threshold of operation. If set
incorrectly, the black level will be adversely affected and the ILA® assembly will
not react properly to incoming light. Perform all ILA® Bias adjustments in a
darkened room.

Chapter 4—Setup Adjustments
To set the ILA® Sensitivity:
1. Under the SYSTEM-PREFERENCES MENU, verify that the SHUTTERS ON HIDE
box is checked.
2. Use the HIDE KEY and hide Red and Green.
3. Toggle the RGB KEY to highlight Blue.
4. Access ILA® SENSITIVITY ADJUST from the MAINTENANCE MENU.
5. Use the up/down arrow keys to select an ILA® Sensitivity of 11 as indicated
in the screen window. This is the default setting and should be acceptable
for general viewing. A lower number may be preferred for HDTV. A higher
setting results in higher brightness but greater image lag and possibly lower
resolution. The ILA® Sensitivity setting depends on the type of viewing
environment. Some trial and error may be needed to get the exact setting for
each environment.
6. Press ESCAPE when the setting is complete.
NOTE: Computer graphics require high resolution but typically are not fast
moving—the ILA® Sensitivity will typically by set in the range of 11 - 15.
Video sources are typically lower resolution but have more movement—the
ILA® Sensitivity is set in the range of 8 - 11.
Changing ILA® Sensitivity requires re-
checking and re-adjusting, if necessary, sensitivity offset, threshold
offset, and shading.
CAUTION!!!
To set the ILA® Bias:
1. Use the same color from the ILA® Sensitivity adjustment
and with the same two (2) colors hidden.
2. Uncheck SHUTTERS ON HIDE. Hide the selected color.
3. Access ILA® BIAS ADJUST from the MAINTENANCE MENU.
Use the up/down arrow keys to decrease the ILA® Bias so the brightest area
of the ILA® image just extinguishes. Then increase the bias level until the
ILA® image just begins to appear on the screen.
NOTE: It is crucial to set the bias level so the selected color just begins to
appear on the screen. Find the spot on the screen where the selected color
first begins to get brighter and use that as the reference point. Adjust the
bias level above and below this point to find the setting where one (1) click
causes an increase in brightness and stop at that point. This insures that the
weakest signal will cause the ILA® assembly to respond properly.
Repeat the above ILA® Sensitivity and ILA® Bias procedures for the remaining
two (2) colors. Save the changes.

4.6. Convergence (XY Registration)
Convergence (XY Registration) overlays the CRT beams onto each other.
XY Registration procedures are required to align the Red, Blue, and Green CRT
beams together on the screen.
NOTE: For a better understanding of what is being accomplished, take the time
now to read the entire Convergence (XY Registration) section before making any
adjustments.
4.6.1. Purpose of Convergence
The XY Convergence adjustments are used to converge or overlay the
Red, Green and Blue CRT images over the entire screen area. The HJT
Model 100 Projector handles many different sources and convergence is
tied directly to a video source. One (1) channel can contain up to 20
different sources with different formats. Each of these sources must have
its own set of convergence data.
4.6.2. Cursor Shapes and Sizes
Three (3) different cursor modes (as described in Table 4.0-3) are used
to make adjustments.
Table 4.0-3 Cursor Modes

Size
Adjust
Various cursor sizes are available to adjust areas. Some areas may
require odd shaped cursors. If a long thin area appears out of
convergence, use a long thin cursor shaped like the area. Use the cursor
size that best fits the area. Some areas may be satisfactory and will not
need any convergence corrections.
The greatest convergence corrections are made at the center of the
cursor—avoid making corrections at the edges of the cursor. Move the
center of the cursor over the area that needs correcting. A cursor with a
long centerline is affected equally all along its centerline by the
adjustments.

To converge (XY Registration):
1. Start with the center of the cursor at the upper left corner.
Note that cursor is off the screen at the top and left (see Figure 4.0-
12 on page 4-26).
2. Make corrections to the area and then, move the center of the cursor
to the numbered areas shown in Figure 4.0-12 in the sequence
shown.
3. Size down to a ¼ screen cursor size. Move down and across the
screen in the sequence shown in Figure 4.0-13—in most cases it will
not be necessary to use a cursor smaller than the one shown.
4. If there are still some smaller areas that need convergence,
size down to a cursor that encloses about nine (9) of the rectangles.
Use the same general pattern as with the previous cursors.
Before beginning adjustments, experiment with the different cursors in
SIZE or MOVE MODES.
If the ADJUST MODE cursor is displayed
CAUTION!!!
(illustrated in Figure 4.0-14 on page 4-27), pressing the arrow keys will

4.8.3. Color Balance (Grey Scale)
Color balancing sets the color balance over the entire screen. This adjustment
may be necessary after performing Threshold and Sensitivity procedures. The
Grey Scale test pattern should be grey throughout the entire screen area with a
normal, gradual brightness transition from bar to bar (no perceived coloration).
If the test pattern is not grey throughout, color balancing is necessary.
Threshold and Sensitivity Offsets can be made for the entire screen to get proper
color balance for the bright and dark areas.
To check for proper Color Balance (Grey Scale):
1. Access GREY SCALE from the TEST PATTERN MENU.
2. Toggle the RGB KEY and verify all colors are selected and on screen.
3. Observe the two or three darkest bars in each of the four (4) sections
of the test pattern. If any color is too prominent in these two or three
bars, adjust the Threshold Offset (see instructions following for
adjusting the Threshold Offset) for that color.
4. Observe the two or three brightest bars in each of the four (4)
sections of the test pattern (refer to Figure 4.0-17 on page 4-31).
If any color is too prominent in these two (2) or three (3) bars, adjust
the Sensitivity Offset (see instructions following for adjusting the
Sensitivity Offset) for that color.
NOTE: A color may appear too weak, due to the other two (2) colors
being too dominant. If so, slightly increase sensitivity offset for the
weak color.
To adjust the Sensitivity Offset for the best Color Balance:
1. Toggle the RGB KEY and select the color that is too prominent in the
brightest bars .
2. Access SENSITIVITY OFFSET from the CONVERGENCE MENU.
3. Use the up/down arrow keys to increase or decrease the Sensitivity
Offset slightly so that the brightest bars in the test pattern are without
color, i.e. grey. Make a note of the offset data number before making
any adjustments in case an error is made and the original setting is
needed. Recheck the test pattern for a normal, gradual transition from
bar to bar. If increasing the Offset, avoid overadjusting any of the
colors. Leave a normal, gradual brightness transition between the
two (2) brightest bars.
NOTE: The two (2) numbers that appear in the box on the screen
represent the lowest and highest Sensitivity settings on the screen. If
either of these settings is at the minimum (0) or maximum (255) there
will be no adjustment range available to adjust the Offset. This means
that one (1) area on the screen has been adjusted too high or too low
during the Sensitivity adjustment and is restricting the Offset
adjustment.
Before the Offset can be adjusted, this area must be increased or
decreased to allow for more range to perform the Offset adjustment.

To adjust the Threshold Offset for the best color balance:
1. Toggle the RGB KEY and select the color that is too prominent in the
dark bars .
2. Access THRESHOLD OFFSET from the CONVERGENCE MENU.
3. Use the up/down arrow keys to slightly increase or decrease the
Threshold Offset so the darkest bars in the test pattern are without
color, i.e. grey. Make a note of the offset setting before making any
adjustments in case an error is made and original setting is needed.
Recheck the test pattern for a normal, gradual transition from bar to
bar. If increasing the Offset, avoid overadjusting any of the colors.
Leave a normal, gradual brightness transition between the two
brightest bars.
NOTE: The two (2) numbers that appear in the box on the screen
represent the lowest and highest Threshold settings on the screen. If
either of these settings is at the minimum (0) or maximum (255) there
will be no adjustment range available to adjust the Offset. This means
that one (1) area on the screen has been adjusted too high or too low
during the Threshold adjustment and is restricting the Offset
adjustment.
Before the Offset can be adjusted, this area must be increased or
decreased to allow for more range to perform the Offset adjustment.
Recheck the Threshold adjustment to locate this specific area, if
possible, and increase or decrease its level accordingly. If this is not
possible, the Color Balance procedure may have to be repeated.
4. If necessary, recheck and readjust the Sensitivity Color Balance.

4.10. Backing up Settings
The source file parameters previously set up (and any other source files attached
to one channel) can be copied to another channel. Copy parameters if the source
has the same basic parameters but different picture settings. A channel can be
set up for a source with picture settings specific to that source, then copied to
another channel. The channel receiving the copied information can have the
picture settings adjusted for the image that will be received on that channel—two
(2) channels are now set up for the same type of source but with different picture
settings. This function saves time and also backs up the settings from the original
channel. When copying from one (1) channel to another channel, verify that both
channels use the same type of VIC. This can be determined by accessing the
SYSTEM-MAINTENANCE MENU and selecting STATUS LIST, which shows the VIC
types.
To Copy Settings from one channel to another channel:
1. Access the CHANNELS MENU and highlight the channel that is to be copied
(highlight by pressing the number or scroll with arrow).
2. Press MODE on the remote.
3. Select COPY from the submenu. This copies the channels’ name, VIC path,
and attached sources into a Paste Buffer.
4. Highlight the channel to PASTE TO; press MODE, select PASTE.
Verify that the channel copied to is blank.
CAUTION!!!
5. If all of the sources that were copied from the first channel are not needed in
the second channel, they can be detached from the second channel.
Change to the SOURCE LIST, then select the unwanted sources with the
arrow keys, then deselect by pressing ENTER to detach them from the
channel.
6. These “copied” channels can be adjusted for Picture and Timing to match
any incoming source for the new channel without affecting the original
source from the first channel. Gemometry, Conversion, and ILA® Setting are
“shared” by the Source File.
NOTE: For convenience store a list of all available sources in one specific
channel. This can be used as a source “master” list. For example, have all
available sources attached to Channel 99. Use this as a master list from
which any source can be attached at any time. Having all available sources
in one “master” channel avoids having to remember where any specific
source is located and the time involved in hunting through various channels
to find a particular source.

The HJT Model 100 Projector is designed and built to provide years of trouble-free
service—however, some periodic maintenance is necessary to keep the projector
operating at an optimal level.
Use Hughes-JVC Authorized Service only. This protects your equipment
and keeps its warranty in force.
When performing any maintenance, protect yourself and the equipment by
following these guidelines:
Turn the projector off and disconnect the power cord.
Observe all Caution and Warnings.
Allow a discharge time of at least one minute for the high voltage to bleed off
before removing the power plug.
Do not turn off the circuit breaker at the rear of the projector until the arc lamp
cooling fans have automatically stopped running.
5.1. Preventive Maintenance
Avoid direct sunlight, moisture, heat and improper mounting.
Avoid using in a dusty environment.
Provide sufficient ventilation to the fans to avoid overheating of internal
components.
Do not place magnetic equipment near the projector.
Disconnect AC power from the projector before cleaning.
5.1.1. Cleaning the Cabinet
Clean the cabinet periodically with a soft cloth. If the cabinet is heavily
stained, use a mild detergent solution. Never use strong detergents or
solvents such as alcohol or thinner to clean any part of the projector.

Chapter 5—Preventive Maintenance
5.1.2. Cleaning the Projector Lens
Under normal environmental circumstances, clean lenses only when
accumulated dust makes the picture fuzzy. Clean the projection lenses
with a camel hair brush to remove dust or use dry air to blow dust off.
Dampen a lint free cloth with lens cleaning fluid (do not use window
cleaner or alcohol) and wipe the lens clean in a continuous circular
pattern from the center of the lens to the edge.
Only clean lens when absolutely necessary—too frequent cleaning can
destroy the lens coating.
5.1.3. Air Filters
Periodically inspect the air filters at the bottom and rear of the HJT Model
100 Projector for heavy accumulation of dirt and debris that may inhibit
proper air circulation. The air filters can be cleaned with air guns, or
submerged into a mild soap bath, being careful to thoroughly dry the filter
before use.

Appendix A. Extron Switcher Interface to Model 100
This appendix provides instructions on how to set up and configure the HJT Model 100
Projector for proper operation with Extron Switchers 10+, 8, and 4LD.
The baud rate for the Extron switchers is 19200. Since Port A is locked to a baud rate of
9600, Port B should be used for Extron Switchers. The projector port assignment must
be selected and the VIC channel assignment must be edited for a switcher.
To select the Baud Rate:
1. From the MAIN MENU, select #7, SYSTEM, then #4, COMM. SETUP.
2. From the COMM. SETUP menu, select PORT B SPEED.
3. From the SPEED SELECTION LIST, select 19200.
4. Press ESCAPE to go back to the COMM. SETUP level.
To set the projector port assignment:
1. From the COMM. SETUP menu, select PORT B DEVICE.
2. From the DEVICE TYPE list, select #3, VIDEO SWITCHER.
3. Turn power OFF at the remote control.
4. Wait until the Arc Lamp fans have stopped running, and provide a system
“cold boot” by toggling the circuit breaker on the projector rear panel to OFF,
then back to ON.
To edit the VIC channel assignment (refer to Section 4.11 on page 4-39
for more information on editing):
1. From the CHANNELS list, select the channel to assign the switcher.
2. Press MODE. This is a toggle key that brings up a submenu for editing
(pressing MODE again removes the submenu.)
3. Select EDIT from the submenu and press ENTER.
4. Use the right arrow key to toggle over to the third VIC column.
5. Press ENTER and use the up/down arrow keys to select the current switcher
channel number. Press ENTER when the current switcher channel number is
shown.
6. Press ESCAPE to exit the EDIT MODE.
A.1 Extron Switcher Configuration
The Extron switcher must have two (2) important parameters for it to work
optimally. First, it must be in the “Master” mode. If in “Slave” mode, the display
power and video mute buttons are internally inhibited. Second, it must receive a
projector “Power On” message. This message is sent routinely during a projector
“Power On” sequence. If the “Power On” message is not received due to cabling
problems, baud rate problems, projector configuration, or switcher emulation
problems, the video mute will not work properly.
HJT Model 100 User's Guide
Appendix A-1
Download from Www.Somanuals.com. All Manuals Search And Download.
Appendix A—Extron Switcher Interface to Model 100
In addition, all Extron switchers must be configured to use HJT protocols and
19200 baud rate (Hughes-JVC emulation). This is usually done at Extron and a
“Configured for Hughes-JVC” sticker is placed on the back of the unit. The Extron
Service Manual for each unit describes how to reset the system to a state
compatible with the HJT protocol, if necessary.
A.2 Extron User’s Manual Inaccuracies
Early revisions (up to Rev C) of the Extron Model 8 and 10 User’s Manual,
describe incorrect configuration procedures for setting Master mode. Specifically,
the description shows that when switch 4 of the address switch block is set to the
closed position it enables the configuration mode. The correct position for this
switch is the opened position. A correct example for setting the Model 8 and 10
switchers is detailed below.
A.3 Key Operational Differences Between Models
The switcher firmware for Model 8 and 10+ function differently from the Model 4
firmware. Switching on the Model 8 and 10+ always occurs independently of the
projector. For example, when a channel switch is pressed on the Model 8 and
10+, the switcher automatically selects that channel after a short time period (~2
seconds). This channel switching occurs even if a projector is not connected to a
switcher. When a projector is connected to a Model 8 or 10+ (and the
communication interface is working properly) and a channel switch is pressed, the
projector normally changes the channel immediately (before the 2-second time
period has expired).
On the Model 4LD, there is no automatic channel switching. Channel switching is
prohibited unless commanded by the projector. If the communication interface
between the switcher and projector is not functioning properly, no channel
switching occurs.
A.3.1 Switcher to Projector Configuration Example
The following provides an example of how to configure an Extron Model 8
Switcher to a HJT Model 100 Projector:
1. Connect the switcher to the Model 100, Port B.
2. Set Comm. Setup to Port B.
3. Set the Port B baud rate to 19200.
4. Turn power off at the remote control (or PC).
5. Wait at least one (1) minute, for the system to reach an “Off” state
from Step 4, then toggle the circuit breaker on the rear panel to Off
and then back to On.
6. Verify that the Model 8 Switcher internal dip switches are set to
Hughes Emulation and the baud rate is set to 19200
(use the Extron manual to confirm this).
7. Turn power on to the Model 8 Switcher.
8. Set the Model 8 external “address” dip switch #4 to the open position.

Appendix A—Extron Switcher Interface to Model 100
9. Set the Model 8 external “address” dip switch #5 to the closed
position.
10. Wait 10 seconds.
11. Set Model 8 external “address” dip switch #4 to the closed position.
12. Turn power on at the remote control.
13. Edit the Model 100 VIC channel assignment.
NOTE: Steps 8 and 11 are incorrectly stated in early versions
(Rev C or earlier) of the Extron System 8 and 10 User’s Manual.
The correct steps are shown above.
A.3.2 Failure Diagnostics
If the channel change, video mute and power buttons on the switcher ALL
do not work properly, check the cabling, baud rate, or emulation. This is
an indication that data is not being sent properly between the switcher
and the projector.
If the channel change buttons work, but the video mute and power
buttons do not, check the switcher master mode setting. This is an
indication that the switcher is in slave mode.
If the channel change and power buttons work, but the video mute button
does not work, turn power off on the remote (or PC), wait until the Arc
Lamp fans have stopped running, then toggle the projector circuit to Off.
This problem is an indication that the switcher did not receive the
projector “Power On” command.

Appendix B—Configuration Data
Export / Import Procedures (Rev 1.0.0)
HJT Model 100 Projector Appendix B defines the steps to perform a Configuration Data
Export and Import from the projector to a host computer. The host computer can be any
system that has RS232 download and upload capability, including an IBM-PC
compatible, an Apple MacIntosh, or a UNIX system—the following procedures are for an
IBM-PC running the WINDOWS 3.1 OS. We will use the WINDOWS TERMINAL application
for communication with the projector. Other terminal emulation programs can be used
(i.e.: PROCOMM) but all testing has been done with the TERMINAL application.
Appendix B Note 1
The TERMINAL application setup is the same as for controlling the projector via an
ANSI TERMINAL (refer to HJT Model 100 Projector User’s Guide, Chapter 3)
Appendix B Note 2
Export/Import can be performed on either Port A or Port B. The Port must be
configured for ANSI TERMINAL.
Port A speed is determined by Dip Switch #4 on the System Controller
board. ON is 9600 baud, OFF is 19200 Baud.
Port B can be configured for 2400, 9600 (default), or 19200 through the
COMM SETUP MENU.
If both Port A and Port B are ANSI TERMINALS, use Port A for Export/Import,
by setting Port A device = None, or Switcher, or Tethered Remote,
and set Port B Device = ANSI.
Remember to POWER OFF (CONTROL + P) and HW RESET (circuit breaker—on
rear panel) after changing any configuration parameters, OR POWER OFF, then
press CONTROL + SHIFT + ^ to reset.
Your computer must have a 16550 UART
WARNING!
installed on the COMM PORT TO use 19200 Baud— use 9600 Baud if you
are not sure. An unbuffered 8550 UART will lose data during EXPORT,
which cannot be detected until a later IMPORT is attempted. With either
Baud, always use SOFTWARE FLOW CONTROL (XON/XOFF).

7.0 Glossary Of Terms
Active Channel
The channel presently being viewed on the screen.
During operation and setup, the channel on which the
setup adjustments are being made-indicated by a pointer
in the Channels list.
Amorphous
Arc Lamp
Without definite form; not crystallized.
The xenon arc lamp. Contains xenon gas under
pressure. Produces dangerously intensive light with
hazardous levels of ultraviolet and infrared radiation.
It operates at very high temperatures.
Aspect Ratio
Autoselect
The ratio of the picture width to picture height. The
standard U.S. television aspect ratio is four units wide to
three units high (4:3). High Definition Television (HDTV)
is 16:9.
The ability of the HJT Model 100 Projector to
automatically match the parameters (such as scan rates,
sync types etc.) of an internal source file (for the active
channel) to the parameters of an incoming video source.
If the external video source changes, the Autoselect
feature automatically matches it to the internal source file
with the closest parameters.
Blanking
Bow
Adjustment used to mask out unwanted areas on the
picture edges. An unblanked image displays the entire
image raster on the screen.
Distortion caused by a curved vertical or horizontal
centerline resulting in the entire image being bent in the
right/left or up/down direction.
Brightness
Channel
Overall or average brightness of a display, setting black
at 0%. Used with Contrast adjustment for best picture
display.
An Autoselect group of up to 20 source files, using one
specific VIC/switch number, set up to accept up to 20
sources with different parameters such as horizontal and
vertical scanning rates, interlaced/noninterlaced scanning,
± sync levels. A channel defines the input path for a source.
Copy Channel
Projector function used to copy VIC address, Picture and
Timing, Adjustment data, and a list of attached Source
Files from one channel to any of the other 99 channels.

Chapter 7—Glossary
Copy Source
Used to copy Geometry, Convergence, Shading, ILA®
Settings and Adjustment data to another of the 20
source files.
Cold Mirror
Mirror that passes infrared light so that its reflection
contains only "cold' light that does not transmit
appreciable heat. As a result of infrared heat radiation,
"cold" mirrors can get quite hot.
Composite Video
Contrast
Means of transmission sending the complete video
signal consisting of chrominance, luminance and the
sync signals. It is the NTSC, PAL, and SECAM standard.
The ratio between the dark and light areas of a television
picture. Used with Brightness adjustment for best picture
display.
Convergence
The process of controlling CRT beam deflection to keep
the Red, Green and Blue beams properly aligned when
scanning the raster. Poor convergence shows up as
color fringing. Convergence adjustment compensates for
the physical separation of the R, G and B tubes by
aligning their output at a fixed distance from the
projector. Convergence adjustments include X,Y-Axis
Convergence and Shading.
CRT (Cathode Ray Tube)
Dichroic Mirrors
The display device used to project images on to the ILA®.
The white light of the xenon arc lamp is separated into
red, green and blue by means of dichroic mirrors which
reflect only one color and pass all others.
Edge Linearity Adjustment Corrects for improper grid spacing at the edges of the
image. This adjustment has limited range. The edge
linearity adjustment is performed on green only and
affects R, G and B.
Ganged
When R and B are ganged to Green, green is set first,
then R and B are set to match G. Thereafter, if R or B
are visible on screen, any adjustments to G will affect all
three colors.
Grey/Pluge
HDTV
Test pattern of black-to-white gradation bars with two
black and white squares superimposed at the center.
Used to set Black level (G2) and Sensitivity Offset.
High Definition Television. Has approximately twice the
horizontal and vertical resolution of standard NTSC.
HDTV systems are wide aspect ratio systems.

Hue
Also referred to as tint. A specific color such as blue,
pink or aqua. Hue or tint control on a display device
adjusts red/green balance.
ILA®(Image Light Amplifier ) A device that uses low-intensity images to phase
modulate a high-intensity light through a liquid crystal
layer. It is the key component in producing very bright,
high resolution images from Hughes-JVC large-screen
projectors.
Intensity
Concentration of information or what would be seen if a
black and white version of the image is displayed.
I/R Windows
Receives projector control signals from the I/R remotes.
Keystone Adjustment
Corrects lines nearest to the screen edge to make them
straight and parallel to the center line of the test pattern
or square to the screen edge. The keystone adjustment
is performed on green only and affects RGB.
Keystoning
Distortion resulting from having the projector not placed
on axis with respect to the screen.
Lamp Assembly
Behind the optics assembly, the arc lamp and "cold"
mirror are mounted in a chamber.

Chapter 7—Glossary
Linearity Adjustment
Corrects for improper horizontal and vertical grid spacing
on an image. With distorted linearity, lines in the grid are
spaced closer together on one side of the image and
farther apart on the other. The linearity adjustment is
performed on green only and affects RGB.
Luminance
Abbreviated as "Y." The portion of the signal that
contains the black and white information, which affects
brightness.
Monochrome
Multisync Monitor
Single color and refers to monitors that display only one
color along with black, such as white on black, black on
white, green on black and amber on black.
A display monitor that adjusts automatically to the
synchronization frequency of the video display board
that's sending signals to it. Multisync monitors can
adjust to a range of frequencies, but not all of them.
Noise
NTSC
Undesirable electrical interference of a signal.
(National Television Standards Committee) The NTSC
governs the standard for television and video playback
and recording in the United States. The NTSC standard
is 525 lines of resolution and is transmitted at 60 half
frames (interlaced) per second.
Optics Module
Contains the optics used to transmit light from the arc
lamp to the projection channels (blue, green and red).
Orthogonal
At right angles.
Overscanning
Displaying less than the complete area of an image to a
viewer (i.e., scanning beyond the visible area). All TV
sets are overscanned at least slightly, so that viewers do
not see blanking.
PAL
(Phase Alternate Line) The 625-line, 50-field system
used in the UK, Western Europe, Scandinavia, Australia,
South Africa and other countries.
Phase adjustment
Positions the input image (test pattern, video, graphics,
etc.) on the CRT raster. If phase is misadjusted, the
image may "wrap around" the edges or be positioned off
the screen.
Pincushion Adjustment
Corrects for warped distortion at the sides or top and
bottom of the image. The pincushion adjustment affects
RGB.

Chapter 7—Glossary
Raster
The area illuminated by the scan lines on a CRT.
Resolution
The degree of sharpness of a displayed or printed
character or image; the amount of detail in a picture. On
a display screen, resolution is expressed as the number
of horizontal dots (columns) by the number of vertical
lines (rows). For example, a 680 x 400 resolution means
680 dots across each of 400 lines.
Retrace
The blanked-out line traced by the scanning beam of a
picture tube as it travels from the end of any horizontal
line to the beginning of either the next horizontal line or
field. The beam is turned "off" during retrace.
RGB (Red, Green, Blue)
Refers to the method of recording and generating colors
in a video system. On a television or color monitor,
colors are displayed as varying intensities of Red, Green
and Blue dots. When R, G and B are all turned on high,
white is produced. When all dots are turned off, the base
color of the screen, (black) appears.
RGB X-hatch
S-VHS
Test Pattern. Used for convergence of the Red, Green,
and Blue light beams.
A high band video recording process for VHS that
increases picture quality and resolution capability. S-VHS
tape machines use a special output terminal which allows
separate output of luminance (Y) and chrominance (C)
picture information to monitors equipped with S-Video
inputs.
S-Video
SAP
A video signal that has the luminance (Y) information
separated from chrominance (C) information.
(Second Audio Program) The MTS system for television
also provides the ability to send an additional audio
signal, called Second Audio Program (SAP).
Saturated Color
Scan
1) A color as far from white, black or gray as it can be.
2) A display misadjustment that results in unnaturally
bright colors.
To scan is to move across a picture frame one line at a
time, either to detect the image, as in an analog or digital
camera, or to refresh a CRT-based video screen.
Scan Line
Scan Rate
SECAM
One of many horizontal lines in a frame.
The frequency of line scanning for a monitor or projector.
"Sequential couleur a memoire" (sequential color with
memory). The French color TV system also used within
the Soviet Union. It is not compatible with NTSC or PAL.

result of high resolution, or it might be an optical illusion
caused by image enhancement or by visible edges in a
display, such as the vertical stripes of an aperture grille
CRT.
Size Adjustment
Skew
Fits the size of the projected image to the screen size.
Distortion caused by the vertical or horizontal centerline
not being exactly vertical or horizontal resulting in an
image that “leans” right/left or up/down.
