Glossary
This section explains easily terms that are used with the projector and difficult terms that are not explained in the text of this guide. For details, refer to 
other commercially available publications.
AMX Device Discovery
AMX Device Discovery is a technology developed by AMX to facilitate AMX control systems for easy operation of the target 
equipment.
Epson has implemented this protocol technology, and has provided a setting to enable the protocol function (ON).
See the AMX Web site (www.amx.com) for more details.
DHCP
An abbreviation of Dynamic Host Configuration Protocol, this protocol automatically assigns an IP Address to equipment 
connected to a Network.
HDCP
HDCP is an abbreviation for High-bandwidth Digital Content Protection. It is used to prevent illegal copying and protect 
copyrights by encrypting digital signals sent over DVI and HDMI ports. Digital images protected by HDCP technology can be 
projected with this projector because the projector's DVI-D and HDMI input ports are compatible with HDCP. However, the 
projector may not be able to project images protected with updated or revised versions of HDCP encryption.
HDTV
An abbreviation for High-Definition Television that refers to high-definition systems which satisfy the following conditions.
•Vertical resolution of 720p or 1080i or greater (p = Progressive, i = Interlace)
•Screen Aspect Ratio of 16:9
•Dolby Digital audio reception and playback (or output)
IP Address
A number to identify a computer connected to a Network.
S-Video
A Video signal which has the luminance component and color component separated to provide better image quality.
Refers to images that consist of two independent signals: Y (luminance signal) and C (color signal). 
SDTV
An abbreviation for Standard Definition Television that refers to standard television systems which do not satisfy the conditions 
for HDTV High-Definition Television. 
SNMP
An abbreviation for Simple Network Management Protocol, which is the protocol for monitoring and controlling devices such as 
routers and computers connected to a TCP/IP Network.
sRGB
An international standard for color intervals that was formulated so that colors that are reproduced by video equipment can be 
handled easily by computer operating systems (OS) and the Internet. If the connected source has an sRGB mode, set both the 
projector and the connected signal source to sRGB.
SVGA
A type of video signal with a resolution of 800 (horizontal) ^ 600 (vertical) dots that is used by IBM PC/AT-compatible computers. 
SXGA
A type of video signal with a resolution of 1,280 (horizontal) ^ 1,024 (vertical) dots that is used by IBM PC/AT-compatible 
computers.

VGA
A type of video signal with a resolution of 640 (horizontal) ^ 480 (vertical) dots that is used by IBM PC/AT-compatible computers. 
XGA
A type of video signal with a resolution of 1,024 (horizontal) ^ 768 (vertical) dots that is used by IBM PC/AT-compatible 
computers. 
Aspect Ratio(Aspect Ratio)The ratio between an image's 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. Interlace
A method of image scanning whereby the image data is divided into fine horizontal lines that are displayed in sequence starting 
from left to right and then from top to bottom. The even-numbered lines and odd-numbered lines are displayed alternately. 
Gateway address(Gateway Address)This is a server (router) for communicating across a network (subnet) divided according to subnet masks.Contrast
The relative brightness of the light and dark areas of an image can be increased or decreased 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. 
Component Video
A Video signal which has the luminance component and color component separated to provide better image quality.
Refers to images that consist of three independent signals: Y (luminance signal), Pb and Pr (color difference signals). 
Composite video
Video signals that have the video brightness signals and color 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 (color) signal 
that are contained in the color bar are overlapped to form a single signal.
Subnet mask
(Subnet Mask)
This is a numerical value that defines the number of bits used for the network address on a divided network (subnet) from the IP 
address.
Sync.
The signals output from computers have a specific frequency. If the projector frequency does not match this frequency, the 
resulting images are not of a good quality. The process of matching the phases of these signals (the relative position of the crests 
and the troughs in the signal) is called Synchronization. If the signals are not synchronized, flickering, blurriness, and horizontal 
interference occur. 
Tracking
The signals output from computers have a specific frequency. If the projector frequency does not match this frequency, the 
resulting images are not 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 appear in the signal. 
Trap IP Address
This is the IP Address for the destination computer used for error notification in SNMP.
Dolby Digital
A sound format developed by Dolby Laboratories. Normal stereo is a 2-channel format that uses two speakers. Dolby Digital is a 
6- channel (5.1-channel) system which adds to this a center speaker, two rear speakers, and a sub-woofer. 
Progressive
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.  
						

							Glossary
134
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 to refresh the light-emitting element. The number of refresh operations per 
second is called the Refresh Rate and is expressed in hertz (Hz).
