Aspect Ratio
The ratio between an image's length and its height. Screens with a horizontal:vertical ratio of 16:9, such as HDTV screens, are known as wide screens.
SDTV and general computer displays have an aspect ratio of 4:3.
Component Video
A method that separates the video signal into a luminance component (Y), and a blue minus luminance (Cb or Pb) and a red minus luminance (Cr or
Pr).
Composite video
A method that combines the video signal into a luminance component and a color component for transmission down a single cable.
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.
Control4 Simple Device
Discovery Protocol (SDDP)
Control4 SDDP is a technology developed by Control4 to allow Control4 control systems to acquire device information for the projector. Epson have
implemented this protocol technology, and have provided a setting to enable the protocol function (ON). See the Control4 Web site for more
details.

DHCP
An abbreviation of Dynamic Host Configuration Protocol, this protocol automatically assigns an IP Address
g
to equipment connected to a network.
DICOM
An acronym for Digital Imaging and Communications in Medicine. An international standard that defines image standards and a communications
protocol for medical images.
Gateway Address
This is a server (router) for communicating across a network (subnet) divided according to Subnet Mask
g
.
HDBaseT
The connection standard for consumer electronics determined by the HDBaseT Alliance. Communicates various control signals such as
uncompressed HD video, audio and 100BASE-TX Ethernet using a LAN cable.
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. HDCP2.2 is a copyright protection standard for 4K content.
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
g
, i = Interlace
g
)
• Screen
Aspect Ratio
g
of 16:9
Infrastructure mode
A method for wireless LAN connection in which devices communicate through access points.
Interlace
Transmits information needed to create one screen by sending every other line, starting from the top of the image and working down to the bottom.
Images are more likely to flicker because one frame is displayed every other line.
