Edge tear
An artifact observed in interlaced video where the screen appears to be split horizontally. Edge tears appear when the video feed is out of 
sync with the refresh rate of the display device.
EDID	(Extended	Display	Identification	Data)
Information stored in the projector that can be read by the source.
EDID is used on the HDMI, DVI and VGA inputs, allowing the source to automatically configure to the optimum display settings.
EDTV	(Enhanced	Definition	Television)
A progressive digital television system with a lower resolution than HDTV.
Field
In interlaced video, a part of the image frame that is scanned separately. A field is a collection of either all the odd lines or all the even lines 
within the frame.
Frame
One of the many still images displayed in a sequence to create a moving picture. A frame is made of horizontal lines of pixels. For example, 
a 1920x1080 frame consists of 1080 lines, each containing 1920 pixels. I\
n analog video frames are scanned one at a time (progressive 
scanning) or split into fields for each field to be scanned separately (interlaced video).
Frame rate
The number of frames shown per second (fps). In TV and video, a frame rate is the rate at which the display device scans the screen to 
“draw” the frame.
Frame rate multiplication
To stop low frame rate 3D images from flickering, frame rate multiplication can be used, which increases the displayed frame rate by two or 
three times.

Gamma
A nonlinear operation used to code and decode luminance. It originates from the Cathode Ray Tube technology used in legacy television 
sets.
Ghosting
An artifact in 3D image viewing. Ghosting occurs when an image intended \
for one eye is partially seen by the other eye.
Ghosting can be removed by optimizing the dark time and sync delay.
HDCP (High-bandwidth Digital Content Protection)
An encryption scheme used to protect video content.
HDTV	(High	Definition	Television)
A television system with a higher resolution than SDTV and EDTV. It can be transmitted in various formats, notably 1080p and 720p.
Hertz (Hz)
Cycles per second.
Horizontal Scan Rate
The rate at which the lines of the incoming signal are refreshed. The rate is set by the horizontal synchronization from the source and 
measured in Hertz.
Hs + Vs
Horizontal and vertical synchronization.
Hue
The graduation (red/green balance) of color (applicable to NTSC).

APPENDIX F: GLOSSARY OF TERMS
Interlacing
A method of updating the image. The screen is divided in two fields, one containing every odd horizontal line, the other one containing the\
 
even lines. The fields are then alternately updated. In analog TV interlacing was commonly used as a way of doubling the refresh rate without 
consuming extra bandwidth.
Interleaving
The alternation between left and right eye images when displaying 3D.
LED (Light Emitting Diode)
An electronic component that emits light.
Letterboxing
Black margins at the top and bottom of the image. Letterboxing appears w\
hen a wider image is packed into a narrower frame without 
changing the original aspect ratio.
Lumen
A photometric unit of radiant power. For projectors, it is normally used to specify the total amount of emi\
tted visible light.
Luminance
Also known as ‘Y’, this is the part of a Component Video signal which affects the brightness, i.e. the black and white part.
Noise
Electrical interference displayed on the screen.
NTSC (National Television Standards Committee)
The United States standard for television - 525 lines transmitted at 60 \
interlaced fields per second.

OSD (on-screen display)
The projector menus allowing you to adjust various settings.
Overlapping region
See blend region.
PAL (Phase Alternate Line)
The television system used in the UK, Australia and other countries - 625 lines transmitted at 50 interlaced fields per second.
Pillarboxing
Black margins at the left and right of the image. Pillarboxing appears w\
hen a narrower image is packed into a wider frame without changing 
the aspect ratio.
Pixel
Short for Picture Element. The most basic unit of an image. Pixels are arranged in lines and column\
s. Each pixel corresponds to a micromirror 
within the DMD™; resolutions reflect the number of pixels per line by the number of lines. For example, a 1080p projector contains 1080 
lines, each consisting of 1920 pixels.
Pond of mirrors
Area around the periphery of the DMD™ containing inactive mirrors. The pond of mirrors may cause artifacts, for example during the edge 
blending process.
Pr, Pb
Color difference signals used with ‘Y’ for analog Component Video inputs. They provide information about the signal color. Not to be 
confused with Cr, Cb.
Primary colors
Three colors any two of which cannot be mixed to produce the third. In a\
dditive color television systems the primary colors are red, green and 
blue.

APPENDIX F: GLOSSARY OF TERMS
Progressive scanning
A method of updating the image in which the lines of each frame are drawn in a sequence, without interlacing.
Pulldown
The process of converting a 24 fps film footage to a video frame rate (25 fps for PA L/SECAM, 30 fps for NTSC) by adding extra frames. DP 
projectors automatically carry out reverse pulldown whenever possible.
Resolution
The number of pixels in an image, usually represented by the number of pixels per line and t\
he number of lines (for example, 1920 x 1200).
RGB (Red, Green and Blue)
An uncompressed Component Video standard.
Saturation
The amount of color in an image.
Scope
An aspect ratio of 2.35:1.
SDTV	(Standard	Definition	Television)
An interlaced television system with a lower resolution than HDTV. For PA L and SECAM signals, the resolution is 576i; for NTSC it is 480i.
SECAM (Sequential Color with Memory)
The television system used in France, Russia and some other countries - 625 lines transmitted at 50 interlaced fields per second.
SX+
A display resolution of 1400 x 1050 pixels with a 4:3 screen aspect ratio. (Shortened from SXGA+, stands for Super Extended Graphics 
Array Plus.)

Synchronization
A timing signal used to coordinate an action.
Test pattern
A still image specially prepared for testing a projection system. It may \
contain various combinations of colors, lines and geometric shapes.
TheaterScope
An aspect ratio used in conjunction with a special anamorphic lens to display 2.35:1 images packed into a 16:9 frame.
Throw distance
The distance between the screen and the projector.
Throw ratio
The ratio of the throw distance to the screen width.
TRC (Throw ratio correction)
A special number used in calculating throw distances and throw ratios when the image does not fill the width of the DMD™.
TRC is the ratio of the DMD™ aspect ratio to the image source aspect ratio:
DMD™ aspect ratioSource aspect ratio

TRC is only used in calculations if it is greater than 1.

Vertical Scan Rate
The rate at which the frames of the incoming signal are refreshed. The rate is set by the vertical synchronization from the source and 
measured in Hertz.
Vignetting
Optical cropping of the image caused by the components in the projection\
 lens.  This can happen if too much offset is applied when 
positioning the image using the lens mount.

ZScreen
A special kind of light modulator which polarizes the projected image for 3D viewing. It normally requires that images are projected onto a 
silver screen. The ZScreen is placed between the projector lens and screen. It changes the polarization of the projected light and switches 
between left- and right-handed circularly polarized light at the field rate.
