Glossary
Following is an explanation of some of the terms used in this guide which may 
be unfamiliar or which were not explained in the manual itself. Further 
information can be obtained by referring to other commercially-available 
publications.
5BNCA port used to input analog video signals.
A/V MuteThe momentary canceling of audio and video output. This projector has an [A/V 
Mute] button which you can press to momentarily stop the projection of pictures and 
sound. The picture and sound can be restored by pressing the [A/V Mute] button on 
the projector’s control panel or the remote control once more.
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.
Color 
difference 
signal 
(component)A type of video signal output by video equipment which actually consists of three 
separate signals: a red + luminance signal (R-Y), a luminance signal (Y) and a blue + 
luminance signal (B-Y). Each signal is transmitted along a separate cable. Color 
difference signals generally result in a better image than composite signals (in which 
the red, green and blue signals and the luminance signal are all transmitted along a 
single cable).
Color 
temperatureThe temperature of an object which is emitting light. If the color temperature is high, 
the colors tend to take on a bluish tinge. If the color temperature is lower, the colors 
tend to take on a reddish tinge.
Component 
videoVideo signals which have the video brightness signals and color 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 (color difference signals).
Composite 
videoVideo signals which have the video brightness signals and color signals mixed 
together. The type of signals commonly used by household video equipment (NTSC 
format).
The signals consist of the carrier signal Y (luminance signal) and the chroma (color) 
signal which are contained in the color 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 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 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 2 
minutes. The actual time will vary depending on the external air temperature.
DFPAbbreviation for Digital Flat Panel. Refers to a standard method for digital 
transmission of video signals.
DV IAbbreviation for Digital Visual Interface. Refers to a standard method for digital 
transmission of video signals.
DVI is a standard which has also been applied to digital household electronic 
equipment other than computers. It allows images to be transmitted at higher 
resolutions than for DFP, and also includes a digital signal encoding function.
Fr ee zeThe momentary pausing of image playback only. When the [Freeze] button on the 
projector is pressed, the image playback only can be paused. When the [Freeze] button 
is pressed again, playback resumes.
HDTVAn abbreviation for High-Definition Television. It refers to high-definition systems 
which satisfy the following conditions.
 Vertical resolution of 720P or 1080i or greater 
(P = progressive scanning, i = interlaced scanning)
 Screen aspect ratio of 16:9
 Dolby Digital audio reception and playback (or output) 
						

							102
Interlaced 
scanningA method of image scanning whereby the signal bandwidth used is approximately half 
that required for sequential scanning when images with the same still picture 
resolution are broadcast.
Refresh RateThe light-emitting element of a display maintains the same luminosity and color 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).
Remote 
portConnects an optional remote control receiver.
S-Video 
imagesA video signal which has the luminance component and color component separated in 
order to provide better image quality.
It refers to images which consist of two independent signals: Y (luminance signal), 
and C (color signal).
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 protector 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.
Source promptThe screen display showing the type of signal being input.
sRGBAn international standard for color intervals that was formulated so that colors 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 (DOS/V computers).
SXGAA type of video signal with a resolution of 1,280 (horizontal) x 1,024 (vertical) dots 
which is used by IBM PC/AT-compatible computers (DOS/V computers).
Synchronization
(Sync.)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 synchronization. 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.
USBAn abbreviation for Universal Serial Bus. USB is an interface for connecting personal 
computers to peripheral devices which only support relatively low data transmission 
speeds.
UXGAA type of video signal with a resolution of 1,600 (horizontal) x 1,200 (vertical) dots 
which is used by IBM PC/AT-compatible computers (DOS/V computers).
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 (DOS/V computers).
XGAA type of video signal with a resolution of 1,024 (horizontal) x 768 (vertical) dots 
which is used by IBM PC/AT-compatible computers (DOS/V computers).
YCbCrThe carrier signal which is contained in the color bar signal used in modern TV 
transmissions (NTSC format). The name comes from the Y (luminance) signal and the 
CbCr (chroma [color]) signals.
YPbPrThe carrier signal which is contained in the color bar signal used in high-definition TV 
(HDTV) transmissions. The name comes from the Y (luminance) signal and the PbPr 
(color difference) signals.

List of ESC/VP21 Commands
Command 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.
