							24-GlossaryAppendix.fm7/22/03
Glossary
Complex terms used in this book, or terms not explained in the body of the text, will be briefly explained 
here. For further explanation, please consult commercially available reference texts.
Aspect ratioThe ratio between an images length and its height. Images which have an aspect ratio of 
16:9 are called Widescreen. The aspect ratio for standard images is 4:3.
Color TemperatureThe temperature of an object which is emitting light. When the colour temperature is high, 
colours tend to take on a bluish tinge; when the colour temperature is low, colours tend to 
take on a reddish tinge.
Component VideoA type of video signal which has the video brightness and colour signal information 
separated, in order to provide better image quality. In high-definition TV (HDTV), it refers 
to images which consist of three independent signals: Y (luminance signal), and Pb and Pr 
(colour difference signals).
Composite VideoThe standard home video signal (NTSC, PAL, SECAM) which has the video brightness and 
colour signal information mixed together. Composite video consists of the carrier signal Y 
(luminance signal) and the chroma (colour) signal, combined within the colour bar signal.
ContrastThe relative brightness of the light and dark areas of an image can be increased or decreased 
in order to make text and graphics stand out, or appear softer. Adjusting this particular 
property of an image is called contrast adjustment.
Cool-downThe process used to cool down a projector lamp that is hot from use. Cool-down happens 
automatically when the [Power] button is pressed on the projector or on the remote control 
to turn the projector off. Do not unplug the projector power cable whilst it is cooling down. 
If cool-down is interrupted, heat from the lamp gets trapped inside the projector, potentially 
shortening the life of the lamp and causing projector failure.
Dolby digitalAn audio format developed by Dolby Laboratories. Normal stereo is a 2-channel format 
which uses two speakers, whereas Dolby Digital is a 6-channel (5.1-channel) system which 
adds a centre speaker, two rear speakers and a sub-woofer.
HDTVAn abbreviation for High-Definition Television, it refers to high definition systems which 
satisfy the following conditions.
 Vertical resolution of 750p or 1125i or greater 
(p=Progressive scanning
g, i=Interlaced scanningg)
 Screen aspect ratio of 16:9
 Dolby digital
gl audio reception and playback (or output)
Interlaced scanningEach screen is divided into fine horizontal lines which are displayed in sequence starting 
from left to right and then from top to bottom. This method of image scanning, whereby 
even numbered lines and odd numbered lines are displayed alternately, is called Interlaced 
scanning.
Progressive 
scanningA method of image scanning whereby the image data from a single image is scanned 
sequentially from top to bottom to create a single image.
Refresh RateThe light-emitting element of a display maintains the same luminosity and colour for an 
extremely short time. For this reason, the image must be scanned many times per second in 
order to refresh the light-emitting element. The number of refresh operations per second is 
called the refresh rate, and is expressed in hertz (Hz).
RGB-VideoA term used to describe a video signal most commonly output to computer monitors. RGB 
video is made up of electrical pulses representing the intensities of the three primary colours 
of light, red, green and blue. A fourth or fifth pulse carries timing information.
SCARTA 21pin rectangular shaped connector for transmitting audio and video signals between TV, 
VTR and AV equipment. RGB, S-Video/Composite video and two audio channels can be 
transmitted.
SDTVAn abbreviation for Standard Definition Television. It refers to standard television systems 
which do not satisfy the conditions for High-Definition Television.
Security lockA device consisting of a projector case with a hole in it that a commercially-available theft-
prevention cable can be passed through in order to secure the device to a table or pillar. This 
projector is compatible with the Microsaver Security System manufactured by Kensington.
Squeeze modeThe method of compressing 16:9 Widescreen images and recording them on video software 
as 4:3 images.
When projecting with Squeeze mode on, the images will return to their original 16:9 format.

SVGAA type of video signal with a resolution of 800 (horizontal) × 600 (vertical) dots which is 
used by IBM PC/AT-compatible computers.
S-VideoA type of video signal which has the video brightness and colour signal information 
separated, in order to provide better image quality. It refers to images which consist of two 
independent signals: Y(luminance signal), and C (colour signal).
Sync.
(Synchronisation)The signals output from computers have a specific frequency. Image quality will suffer if the 
projector frequency and the computer frequency do not match. The process of matching the 
phases of these signals (the relative position of the crests and troughs in the signal) is called 
synchronisation. If the signals are not synchronised, problems such as flickering, 
blurriness and horizontal interference can occur.
TrackingThe signals output from computers have a specific frequency. Image quality will suffer if the 
projector frequency and the computer frequency do not match. The process of matching the 
frequency of these signals (the number of crests in the signal) is called tracking. If 
tracking is not carried out correctly, wide vertical stripes will appear in the projected images.
VGAA type of video signal with a resolution of 640 (horizontal) × 480 (vertical) dots which is 
used by IBM PC/AT-compatible computers.
XGAA type of video signal with a resolution of 1,024 (horizontal) × 768 (vertical) dots which is 
used by IBM PC/AT-compatible computers.
YCbCrThe carrier signal contained in the colour bar signal used in modern (NTSC) TV 
transmissions. The name comes from the Y (luminance) signal and the CbCr (chroma 
(colour)) signals.
YPbPrThe carrier signal contained in the colour bar signal used in high-definition TV (HDTV) 
transmissions. The name comes from the Y (luminance) signal and the PbPr (colour 
difference) signals.
