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.

generate a large number of colors.
The ratio of the width of an image to its height, such as the 4:3 aspect ratio common
in video output.
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 at which serial communications travel from their origin. In this projector,
the RS-232 or RS-422 default baud rate of 19200 can be changed to match a
controlling device. The switcher baud rate of 9600 cannot be changed.
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.

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.
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.
A Direct Digital Interface signal can be supplied to the projector via an optional
digital input module installed in 
INPUT 2. 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 Module).

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.
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.
For this projector, horizontal offset is expressed as the maximum percentage 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
is limited when 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 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 by poor
Keystone adjustment in X10 software (optimized for X10 only).
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.

spot from the right edge to the left edge.
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.
The horizontal or vertical frequency at which images are generated.
One horizontal line on the display.
A video output format of some video tape and disk players (used primarily in
France). SECAM (Sequential Couleur á Mémoire) signals are similar in resolution
and frequency to PAL signals. The primary difference between the two standards is
in the 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 is identified at the projector as  
Input1,  Input2,  Input3 or  Input4, or as other user-
defined numbers. A source may have numerous corresponding channels defined and
recognized by the projector. See Input.
See Channel.
The diameter of the smallest dot that can be generated by a CRT projector. This
projector has a fixed spot (pixel) size.
A signal selector, such as the Marquee Signal Switcher, 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. Retrace Time

the blanking time.
A type of RGB video with digital characteristics.
A wire connecting a single video source to a display device, such as a projector, must
be terminated by a resistance (usually 75S for video).
The distance between the front feet of the projector and the screen. Also called
Projector-to-Screen Distance”. Always use the correct throw distance formula to
calculate the proper throw distance (±5%) required for your lens.
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.
For this projector, vertical offset is expressed as the maximum percentage 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 is limited
when 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
