Following is an explanation of some of the terms used in this guide which may be unfamiliar or which were 
not explained in the text of this guide itself. Further information can be obtained by referring to other 
commercially-available publications.
Aspect ratioThe ratio between an images length and its height. HDTV images have an aspect ratio of 
16:9 and appear elongated. The aspect ratio for standard images is 4:3.
Colour temperatureThe temperature of an object which is emitting light. If the colour temperature is high, 
the colours tend to take on a bluish tinge. If the colour temperature is lower, the colours 
tend to take on a reddish tinge.
Component videoVideo signals which have the video brightness signals and colour signals 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 videoVideo signals which have the video brightness signals and colour signals mixed together. 
The type of signals commonly used by household video equipment (NTSC, PAL and 
SECAM formats). 
The carrier signal Y (luminance signal) and chroma (colour) signal which are contained 
in the colour bar are overlapped to form a single 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 more clearly, or to make them 
appear softer. Adjusting this particular property of an image is called contrast 
adjustment.
Cool-downThe cooling process for the projectors lamp unit continues even after the [Power] button 
on the projectors control panel or the remote control has been pressed to turn off the 
lamp. After the lamp turns off, the cooling fan continues operating, but all button 
operations are disabled. The length of time that this is happening is called the cool-down 
period. The cool-down period lasts for about 20 seconds. The actual time will vary 
depending on the external air temperature.
Dolby DigitalA sound format developed by Dolby Laboratories. Normal stereo is a 2-channel format 
which uses two speakers. Dolby Digital is a 6-channel (5.1-channel) system which adds 
to this 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
, i = interlaced 
scanning)
Screen aspect ratio
 of 16:9
Dolby Digital
 audio reception and playback (or output)
Interlaced scanningA method of image scanning whereby the image data is divided into fine horizontal lines 
which are displayed in sequence starting from left to right and then from the top to the 
bottom of the screen. The even-numbered lines and odd-numbered lines are displayed 
alternately.
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. Because of this, 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).
Resize displayThis function is use to project computer images that have a resolution or more than or 
less than the projectors panel resolution to be projected so that they fill the whole of the 
projection area.
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.

sRGBAn international standard for colour intervals that was formulated so that colours which 
are reproduced by video equipment can be handled easily by computer operating systems 
(OS) and the Internet.
SVGAA type of video signal with a resolution of 800 (horizontal) x 600 (vertical) dots which is 
used by IBM PC/AT-compatible computers.
S-VideoA video signal which has the luminance component and colour component 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. If the projector frequency 
does not match this frequency, the resulting images will not be of a good quality. 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 synchronized, 
problems such as flickering, blurriness and horizontal interference can occur.
TrackingThe signals output from computers have a specific frequency. If the projector frequency 
does not match this frequency, the resulting images will not be of a good quality. 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.
VG AA type of video signal with a resolution of 640 (horizontal) x 480 (vertical) dots which is 
used by IBM PC/AT-compatible computers.
XGAA type of video signal with a resolution of 1024 (horizontal) x 768 (vertical) dots which 
is used by IBM PC/AT-compatible computers.
YCbCrThe carrier signal which is contained in the colour bar signal used in modern TV 
transmissions. The name comes from the Y (luminance) signal and the CbCr (chroma 
(colour)) signals.
YPbPrThe carrier signal which is 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.
