Glossary
The 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.
Component video
Video 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 video
Video signals which have the video brightness signals and 
color signals mixed together. The type of signals 
commonly used by household video equipment (NTSC
, 
PA L
 and SECAM formats).
Video signals which consist of a carrier signal Y 
(luminance signal) within the color bar signal, and a 
chroma or color signal (CbCr).
Cool-down
This is the process by which the projectors lamp is cooled 
down after it has become hot through use. It is carried out 
automatically when the [Power] button on either the 
remote control or the projectors control panel has been 
pressed to the projector off. Do not disconnect the power 
cable while cool-down is in progress, otherwise the cool-
down process will not work properly. If the cool-down 
period is not allowed to finish normally, the projectors 
lamp and internal components will remain at high 
temperatures, and this may shorten the useful life of the 
lamp or cause problems with the operation of the projector. 
The cool-down period lasts for about 30 seconds. The 
actual time will vary depending on the external air 
temperature.
DHCP
Abbreviation for Dynamic Host Configuration protocol, 
which is a protocol for automatically assigning an IP
 
address
 for devices that are connected to a network.
Gateway
A server (router) that is used for communication over a 
network (subnet) that is divided up using subnet masks
.
HDMI
An abbreviation for High Definition Multimedia Interface, 
and refers to a standard for digital transmission of high-
definition images and multi-channel audio signals.
HDMI is a standard that is targeted towards household 
digital equipment and computers that allows digital signals 
to be transmitted in their original high quality without 
compression, and it also includes a digital signal 
encryption function.
HDTV
An 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, i = interlaced
)
Screen aspect of 16:9
Dolby Digital audio reception and playback (or output)
Interlace
A 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.
IP address
A series of numbers that identifies a device that is 
connected to a network.
MAC address
Abbreviation for Media Access Control address. A MAC 
address is a unique ID number that is assigned to each 
network adapter. All network adapters are assigned this 
unique address, and these are used as the basis for 
communication between each network adapter.
NTSC
An abbreviation for National Television Standards 
Committee, and a format for ground-based analogue 
colour television broadcasts. This format is used in Japan, 
North America and Central and South America.
PA L
An abbreviation for Phase Alternation by Line, and a 
format for ground-based analogue colour television 
broadcasts. This format is used in Western European 
countries except France, and also in Asian countries such 
as China and in Africa.
Refresh rate
The 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).
S-Video
A 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).
SDTV
An abbreviation for Standard Definition Television. It 
refers to standard television systems which do not satisfy 
the conditions for HDTV
.
SECAM
An abbreviation for Sequential Couleur A Memoire, and a 
format for ground-based analogue colour television 
broadcasts. This format is used in France, Eastern Europe 
and the former Soviet Union, the Middle East and Africa.
Security lock
A 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.

SNMP
Abbreviation for Simple Network Management Protocol. 
In TCP/IP networks, this protocol is used for 
communication between routers and other devices that are 
connected to the network such as computers and terminals 
so that these devices can be monitored and controlled over 
the network.
sRGB
An 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.
Subnet mask
A series of numbers that define the number of bits to be 
used for network addresses in a network (subnet) that is 
divided up according to IP addresses
.
SVGA
A type of image signal with a resolution of 800 
(horizontal) 
× 600 (vertical) dots which is used by IBM 
PC/ AT-compatible computers.
SXGA
A type of image 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 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.
Tracking
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 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.
Trap IP address
An IP address for the destination computer when 
SNMP
 reports that a problem has occurred.
VGA
A type of image signal with a resolution of 640 
(horizontal) 
× 480 (vertical) dots which is used by IBM 
PC/ AT-compatible computers.
XGA
A type of image signal with a resolution of 1,024 
(horizontal) 
× 768 (vertical) dots which is used by IBM 
PC/ AT-compatible computers.
YCbCr
The carrier signal which is contained in the color bar signal 
used in modern TV transmissions. The name comes from 
the Y (luminance) signal and the CbCr (chroma [color]) 
signals.
YPbPr
The 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.
