APPENDIX F: GLOSSARY OF TERMS
Appendix F: Glossar y Of  Terms
1080p
An HDTV resolution which corresponds to 1920 x 1080 pixels (a widescreen aspect ratio of 16:9).
3D active glasses
Wireless battery-powered glasses with LCD shutters. Synchronization info\
rmation is communicated to the glasses by means of an infrared 
(IR) or radio frequency (RF) emitter which is connected to the Sync Out terminal on the projector. IR or RF pulses are transmitted by the 
emitter to signal when the left eye and right eye images are being displ\
ayed. The glasses incorporate a sensor which detects the emitter’s 
signal and synchronises the left and right eye shutters with the project\
ed image.
3D passive glasses
Passive glasses do not require a power source to work. Light with left-hand polarisation can pass through the left lens and light with right-
hand polarisation can pass through the right-hand lens. These glasses are used in conjunction with another device which polarize\
s the image, 
such as a ZScreen.
Adjust lines
A pattern applied to the image where its edge is to be blended with anoth\
er image. Adjust lines are used to position the projectors in the array 
during the edge blend process.
Anamorphic lens
A special lens which, when used with the TheaterScope aspect ratio, allows watching 2.35:1 content packed in a 16:9 source.
Aperture
The opening of the lens that determines the angle through which light tr\
avels to come into focus.

APPENDIX F: GLOSSARY OF TERMS
Aspect ratio
The proportional relationship between the width and the height of the projected image. It is represented by two numbers separated by a colon, 
indicating the ratio of image width and height respectively: for example, 16:9 or 2.35:1.
Not to be confused with resolution.
Blanking (projection)
The ability to intentionally turn off, that is, set to black, areas around the edges of the projected image. It is sometimes referred to as “curtains” 
since it can be used to blank an area of image that literally falls on t\
he curtains at the side of the screen in a movie theater. Usually no image 
resizing or geometric correction takes place and the “blanked” par\
t of the image is lost.
Not to be confused with horizontal and vertical blanking (video signal).
Blanking (video signal)
The section of the video signal where there is no active video data.
Not to be confused with blanking (projection).
Blend region
The area of the image that is to overlap with another image in an edge blend setup. Sometimes called overlapping region.
Brightness (electronic control)
A control which adds a fixed intensity value to every pixel in the display, moving the entire range of displayed intensities up or down, and is 
used to set the black point in the image (see Contrast). In Component Video signals, brightness is the same as luminance.
Brightness (optical)
Describes how ‘bright’ an image that is projected onto a screen appears to an observer.
C
See Chrominance.

APPENDIX F: GLOSSARY OF TERMS
Chrominance
Also known as ‘C’, this is the component, or pair of components, of a Component Video signal which describes color difference information.
Color difference
In Component Video signals, the difference between specified colors and the luminance component. Color difference is zero for 
monochrome images.
Color gamut
The spectrum of color available to be displayed.
Color temperature
The position along the black body curve on the chromaticity diagram, normally quoted in Kelvin. It takes into account the preset values for 
color balance in the service set-up to take up the variations in the pri\
sm. The projector allows you to adjust this temperature (i.e. adjust the 
picture color temperature).
Component video
A three-wire or four-wire video interface that carries the signal split i\
nto its basic RGB components or luminance (brightness) and two-color-
difference signals (YUV) and synchronization signals.
Contrast (electronic control)
The adjustment of the white point of the image without affecting the black point. This increases the intensity range of the displayed image.
Contrast (optical)
The intensity difference between the darkest and lightest areas of the screen.
Cr, Cb
Color difference signals used with ‘Y’ for digital Component Video inputs. They provide information about the signal color. Not to be 
confused with Pr, Pb.

APPENDIX F: GLOSSARY OF TERMS
Crop
Remove part of the projected image.
Alternatively, fit an image into a frame with a different aspect ratio by removing part of the image. The image is resized so that either its 
length or its width equals the length or width of the frame, while the other dimension has moved outside the frame; the excess area is then cut 
out.
Dark time
The time inserted between frames when using 3D active glasses, to avoid ghosting caused by switching time between left and right eye.
DDC (Display Data Channel)
A communications link between the source and projector. DDC is used on the HDMI, DVI and VGA inputs. The link is used by the source to 
read the EDID stored in the projector.
Deinterlacing
The process of converting interlaced video signals into progressive ones.
DHCP (Dynamic Host Configuration Protocol)
A network protocol that is used to configure network devices so that they can communicate on an IP network, for example by allocating an IP 
address.
DMD™ (Digital Micromirror Device™)
The optical tool that transforms the electronic signal from the input so\
urce into an optical image projected on the screen. The DMD™ of a 
projector has a fixed resolution, which affects the aspect ratio of the projected image.
A Digital Micromirror Device™ (DMD™) consists of moving microscop\
ic mirrors. Each mirror, which acts as a pixel, is suspended between 
two posts by a thin torsion hinge. It can be tilted to produce either a bright or dark pixel.
Edge blend
A method of creating a combined image by blending the adjoining edges of \
two or more individual images.

APPENDIX F: GLOSSARY OF TERMS
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. In 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).
