GlossaryFollowing is an explanation of some of the terms used in this guide which may be unfamiliar or which are not explained in the t ext of this guide itself. Further 
information can be obtained by referring to  other commercially-available publications.
5BNC
A port used to input analogue video signals.
Abs. Color Temp.
The temperature of an object which is emitting light. If the absolute colour temperature is high, the colours tend to take on a  
bluish tinge. If the absolute colour temperature is  lower, the colours tend to take on a reddish tinge.
Aspect ratio
The 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.
Component video
Video 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 cons ist of three independent signals: Y (luminance signal), and Pb 
and Pr (colour difference signals).
Composite video
Video signals which have the video bright ness signals and colour signals mixed toge ther. The type of signals commonly used 
by household video equipment (NTSC, PAL and SECAM formats). 
The carrier signal Y (luminance signal) and chroma (colour) si gnal which are contained in the colour bar are overlapped to 
form a single signal.
Contrast
The relative brightness of the light and dark areas of an im age can be increased or decreased in order to make text and 
graphics stand out more clearly, or to make them appear soft er. Adjusting this particular property of an image is called 
contrast adjustment.
Cool-down
This is the process by which the projectors lamp is cooled do wn after it has become hot through use. Cool-down is carried out 
automatically when the [Power] button is pressed to turn off the power. Do not disconnect the power cable while cool-down is 
in progress, otherwise the cool-down process will not work properl y. If the cool-down period is not allowed to finish normally,  
the projectors lamp and internal component s will remain at high temperatures, and this may shorten the operating life of the 
lamp or cause problems with the operation of the projector.
Dolby Digital
A sound format developed by Dolby Laboratories. Normal ster eo is a 2-channel format which uses two speakers. Dolby 
Digital is a 6-channel (5.1-channel) syst em which adds to this a centre speaker two rear speakers and a sub-woofer.
EMP Link 21L
A utility software program that allows the pr ojector to be connected to a computer so that the computer can be used to control 
the projector. For details on acquiring the software and for in structions on using the software and compatible projector 
models, please visit the Web site  http://www.epson.co.uk/support/download/projector.htm
.
HDTV
An abbreviation for High-Definition Televi sion. 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 scanning
A 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 bo ttom of the screen. The even-numbered lines and odd-numbered lines 
are displayed alternately.
Progressive scanning
A method of image scanning whereby the image data from a single  image is scanned sequentially from top to bottom to create 
a single image. 
						

							95
Glossary
Refresh rate
The 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 display
This function is used to project computer images that have a re solution more than or less than the projectors panel resolution 
to be projected so that they fill the whole of the projection area.
SDTV
An abbreviation for Standard Definition Television. It refers to  standard television systems which do not satisfy the conditions 
for High-Definition Television.
Security lock
A 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 mode
In this mode, wide-screen images in 16:9 mode are compressed  in the horizontal direction so that they are stored on the 
recording medium as 4:3 images.
When these images are played back by the projector in squeeze  mode, they are restored to their original 16:9 format.
sRGB
An 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.
SVGA
A type of video signal with  a resolution of 800 (horizontal)  × 600 (vertical) dots which is used by IBM PC/AT-compatible 
computers.
S-Video
A video signal which has the luminance com ponent 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).
SXGA
A type of video signal with a resolution of 1280 (horizontal)  × 1024 (vertical) dots which is used by IBM PC/AT-compatible 
computers.
Sync. (Synchronization)
The signals output from computers and RGB video equipment 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.
Tr a c k i n g
The signals output from computers and RGB video equipment 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 tracki ng. If tracking is not carried out correctly, wide vertical stripes will 
appear in the projected images.
USB
An abbreviation for Universal Serial Bus. USB is an interfac e for connecting personal computers to peripheral devices which 
only support relatively low data transmission speeds.
UXGA
A type of video signal with  a resolution of 1600 (horizontal)  × 1200 (vertical) dots which is used by IBM PC/AT-compatible 
computers.
VGA
A type of video signal with  a resolution of 640 (horizontal)  × 480 (vertical) dots which is used by IBM PC/AT-compatible 
computers. 
						

							96
Glossary
XGA
A type of video signal with a resolution of 1024 (horizontal)  × 768 (vertical) dots which is used by IBM PC/AT-compatible 
computers.
YCbCr
The 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.
YPbPr
The carrier signal which is contained in the colour bar signa l used in high-definition TV (HDTV) transmissions. The name 
comes from the Y (luminance) signal and the PbPr (colour difference) signals.

List of ESC/VP21 CommandsCommand List
When a power ON command is sent to the projector, the power for the 
projector turns on. When the projector is in a command ready state, it 
returns the 3Ah (:) code. Furthermore, when command processing is 
complete, the projector also returns a : code.
The : code status can be used to determine whether the projector is ready 
or busy. If command processing terminates with an error, an error message 
is output and then the : code is sent.
