  User’s Manual     A-1 
This appendix defines the specific terms used in this manual as they apply to this projector. Also included are other 
general terms commonly used in the projection industry. 
The time, inside one horizontal scan line, during which video is generated. 
The ability of a screen to reflect ambient light in a direction away from the line of 
best viewing. Curved screens usually have good ambient light rejection. Flat screens 
usually have less ambient light rejection. 
The video output of most computers and videotape machines. Analog video can 
generate a large number of colors. 
Having or requiring a linear distortion, generally in the horizontal direction. 
Anamorphic lenses can restore a ‘scope’ (CinemaScope) or ‘flat’ format film frame to 
the correct wide-screen appearance by increasing its horizontal proportion.  
The American National Standards Institute is the organization that denotes the 
measurement standard for lamp brightness. 
The ratio of the width of an image to its height, such as the 4:3 aspect ratio common in 
video output. Can also be expressed as a decimal number, such as 1.77, 1.85 or 2.39. 
The larger the ratio or decimal, the wider and “less square” the image. 
The ability of the projector to automatically recognize and synchronize to the 
horizontal and vertical scan frequencies of an input signal for proper display. 
The frequency range of the projectors video amplifier. 
The speed (bits-per-second) at which serial communications travel from their origin.  
The time inside one scan line during which video is not generated. The blanking time 
of the input signal must be equal to or greater than the retrace time of the projector. 
In projection, brightness usually describes the amount of light emitted from a surface 
such as a screen. It is measured in foot-lamberts or candelas per square meter. 
Unit of measure for measuring intensity of light. 
A collection of measurements stored by the projector for a given input source, 
including frequencies, pulse width, polarity, syncs, channel number and location, user-
adjustable display settings, etc. Use channels to switch between a variety of setups 
quickly, automatically recalling previously defined display parameters.

A number that uniquely identifies a specific channel retained in projector memory. 
The projector can retain up to 99 channels. 
A menu item that indicates whether an option is currently in effect (checked) or not 
(unchecked). 
The signal representing the color information (hue and saturation) when the image is 
represented as separate chrominance and luminance. Same as “chroma”. 
The range of colors allowed in a specific system, as defined within a triangular area 
located on the CIE color locus diagram whose corners are the three primaries defined 
in the system. Also known as color space. 
A change in the tint of a white field across an image. 
The coloration (reddish, white, bluish, greenish, etc.) of white in an image, measured 
using the Kelvin (degrees K) temperature scale. Higher temperatures output more 
light. 
See YCbCr or YPbPr. 
The output of video tape players and some computers, characterized by 
synchronization, luminance and color signals combined on one output cable. 
The degree of difference between the lightest and darkest areas of the image. 
The alignment of the red, green, and blue elements of a projected image so that they 
appear as a single element. 
A projection screen which is slightly concave for improved screen gain. Curved 
screens usually have screen gains, which are greater than 1 but viewing angles much 
less than 180
°. Curved screens are not recommended for use with this projector. 
The Display Data Channel VESA standard enables communication between PCs and 
monitors, and is based on E-EDID protocol. 
A “direct digital interface” signal can be supplied to the projector via an optional 
digital input module installed in 
INPUT 5. For example, you can input an SMPTE-
259M signal using a Serial Digital Input Module or input an SMPTE-272M signal 
from a Digital HDTV Serial Input Module.

 User’s Manual     A-3 
The maximum frequency of the pixel clock. Also known as pixel clock rate. 
The Enhanced Extended Display Identification Data standard, established by VESA, 
enables properties (such as resolution) of a display device to be detected by the 
display card in a controlling device such as a PC. The PC, in turn, can then output in a 
matching format to fill the display. Some sources used with the projector are VESA E-
EDID reported. 
A very rapid variation in image brightness caused by a frame rate that is too slow. 
(See Interlace) See also Lamp Flicker. 
The intensity of visible light per square foot. 
The luminance (brightness) which results from one foot-candle of illumination falling 
on a perfectly diffuse surface. 
The frequency at which complete images are generated. For non-interlaced signals, 
the frame rate is identical to the vertical frequency. For interlaced signals, the frame 
rate (also known as field rate) is one half of vertical frequency. 
The ability of a screen to direct incident light to an audience. A flat matte white wall 
has a gain of approximately 1. Screens with gain less than 1 attenuate incident light; 
screens with gain more than 1 direct more incident light to the audience but have a 
narrow viewing angle. For example: An image reflecting off a 10 gain screen appears 
10 times brighter than it would if reflected off a matte white wall. Curved screens 
usually have larger gain than flat screens. 
General Purpose Input Output, used for remote control of a limited number of 
programmable functions by direct signal or dry-contact connection. 
High-definition Television (1035, 1080 and 1125 lines interlace, and 720 and 1080 
line progressive formats with a 16:9 (i.e. 1.77) aspect ratio. 
A display of help information regarding the current task or presentation.  
The frequency at which scan lines are generated, which varies amongst sources. Also 
called horizontal scan rate or line rate. 
The difference between the center of the projected image and the center of the 
projector lens. For clarity, offset is often expressed as the maximum amount of the 
image that can be projected to one side of the lens center without degrading the image 
quality. Horizontal offset ranges can be affected by the type of lens in use, and 
whether or not the image is offset vertically at the same time. 
A circular area of a screen where the image appears brighter than elsewhere on the 
screen. A hot spot appears along the line of sight and moves with the line of sight. 
High gain screens and rear screens designed for slide or movie projection usually have 
a hot spot. 
A physical connection route for a source signal, described by a 2-digit number 
representing 1) its switcher/projector location and 2) its slot in the switcher/projector.

 User’s Manual 
A device, such as the Serial Digital Input Module, that accepts an input signal for 
display by the projector. 
A method used by video tape players and some computers to double the vertical 
resolution without increasing the horizontal line rate. If the resulting frame/field rate is 
too low, the image may flicker depending on the image content. 
A small push-button device for controlling most projector settings and operation. For 
more information, refer to 3.3, Using the Keypad. 
A distortion of the image which occurs when the top and bottom borders of the image 
are unequal in length. Side borders both slant in or out, producing a “keyhole” shaped 
image. It is caused when the screen and lens surface are not parallel, or (in “X” 
models) by poor Keystone adjustment. 
As the lamp ages, the shape of two anodes may changes from two points to a flattened 
state. When this occurs, the arc jumps across the gap from varying points. This is seen 
as image flicker. Turning the Lamp Conditioning feature ON will pulse the lamp and 
gradually “condition” the two anodes back to two points. Lamp Conditioning may 
take seconds, minutes or hours to reach full effectiveness. NOTE: Lamp flicker can 
occur at any time in the lamps life.  The length of time, over which flicker may occur 
varies considerably and unpredictably. This behavior is inherent in UHP lamps. 
The reproduction of the horizontal and vertical size of characters and/or shapes over 
the entire screen. 
When light from a projector is incident on a screen, the light reflects from the screen 
such that the angle of reflection equals the angle of incidence. The Line of Best 
Viewing is along the line of reflection. 
A Christie software feature where samples of output light from a projector trigger 
automatic adjustments in the lamp ballast power in order to maintain a constant light 
output over time. Also known as brightness tracking. 
The method of feeding a series of high impedance inputs from a single video source 
with a coaxial transmission line in such a manner that the line is terminated with its 
characteristic impedance at the last input on the line. 
The unit of measure for the amount of visible light emitted by a light source. 
The signal representing the measurable intensity (comparable to brightness) of an 
electronic image when the image is represented as separate chrominance and 
luminance. Luminance also expresses the light intensity of a diffuse source as a 
function of its area; measured in lumens or candles per square foot (1 lumen per 
square foot = 1 footlambert). SMPTE RP 98 calls for a luminance of 12 to 22 
footlamberts for theatre screens. See: Footlambert. 
The amount of visible light per square meter incident on a surface.

NTSC 3.58 is used primarily in North America and Japan. NTSC 4.43 is less 
commonly used. 
A type of rear-projection screen which re-directs light through the screen to increase 
image brightness in front of the screen. Screen gain is usually greater than 1 but 
audience viewing angles are reduced.

A manufacturer of a digital video recorder/player/server, QuBit, frequently used for 
providing digital cinema data. QuVis image compression uses a proprietary 
technology called Quality Priority Encoding, based on wavelets, in which the user 
selects a quality level based on signal-to-noise ratio. The data rate varies to efficiently 
maintain that quality level. Frames are coded individually. 
A translucent panel for screen projection. Incident light travels through the incident 
surface of a rear screen and forms an image on the other surface. 
The ability to manipulate through software commands the physical size, placement 
and/or aspect ratio of an image.

The time required by the video amplifier of the projector to increase its output from 
10% to 90% of the maximum value. 
The video output (analog or digital) of most computers. Analog RGB video can have 
3, 4, or 5 wires — one each for red, green, and blue, and either none, one or two for 
sync. For three-wire RGB, the green wire usually provides sync. (See TTL Video). 
A common asynchronous data transmission standard recommended by the Electronics 
Industries Association (EIA). Also called serial communication. 
A less common asynchronous data transmission standard in which balanced 
differential voltage is specified. RS-422 is especially suited to long distances. 
The output from certain video tape players and video equipment. S-Video separates 
sync and luminance from color information, typically producing a higher quality 
display than composite video.

way color information is encoded. 
A slidebar is a graphical display of an adjustable setting. The numerical setting often 
represents a percentage but can be a specific unit such as degrees Kelvin. 
The device, such as a computer or VCR, connected to the projector for display. A 
source may have numerous corresponding channels defined and recognized by the 
projector. See Input. 
See Channel. 
A signal selector that can be connected to a projector for the purpose of adding more 
sources. 
This term refers to the part of the video signal that is used to stabilize the picture. 
Sync can occur in three forms: 
1) Composite sync:  the horizontal and vertical components are together on one 
cable. 
2) Sync-on-green:  the sync is part of the green video. 
3) Separate sync or H.SYNC and V.SYNC:  the horizontal and vertical 
components of the sync are on two separate cables. 
The duration of each sync pulse generated by a computer. The sync width is part of 
the blanking time.

A wire connecting a single video source to a display device, such as a projector, must 
be terminated by a resistance (usually 75Σ for video). 
The distance between the front feet of the projector and the screen. Also called 
Projector-to-Screen Distance”. Always use the correct Christie throw distance 
formula to calculate the proper throw distance (±5%) required for your lens. 
Throw ratio = throw distance / screen width. Typically used to differentiate lenses. 
Balance of red-to-green necessary for realistic representation of NTSC signals. 
The ability of a projector to synchronize to inputs with frequencies within a specified 
range. 
The frequency at which images are generated. Vertical frequencies vary amongst 
sources. Also called vertical scan rate. 
The difference between the center of the projected image and the center of the 
projector lens. For clarity, offset is often expressed as the maximum amount of the 
image that can be projected above or below the lens center without degrading the 
image quality. Vertical offset ranges depend on the type of lens in use, and whether or 
not the image is offset horizontally at the same time. 
The signal that is used by display devices (such as projectors) to generate an image. 
This term also refers to the output of video tape/disk players and computers. 
An optional device that converts NTSC 3.58, NTSC 4.4, PAL, PAL-N, PAL-M or 
SECAM to RGB video. 
A specific type of video signal, such as NTSC, PAL, SECAM. This projector can 
automatically recognize and interpret the incoming standard and display accordingly. 
Screens do not reflect equally in all directions. Most light is reflected in a conical 
volume centered around the line of best viewing. Maximum brightness is perceived 
if you are within the viewing cone defined by the horizontal and vertical viewing 
angles. 
The color temperature of white used by the projector. 
The area of an image that is white only. For example, a full white field is an image 
that is white everywhere. A 10% white field is a white area (usually rectangular) that 
occupies 10% of the image; the remaining 90% is black. 
A high-end digital component video signal. 
A high-end analog component video signal. Sometimes called YUV, Component, or 
Y, R-Y, B-Y, the YPbPr signal by-passes the video decoder in this projector.
