This section briefly explains the difficult terms that are not explained in the
text of this guide. For details, refer to other commercially available
publications.
Ad hoc mode A method of wireless LAN connection that communicates
with wireless LAN clients without using an access point.
AMX Device
Discovery
AMX Device Discovery is a technology developed by AMX
to facilitate AMX control systems for easy operation of the

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 Vid‐
eo
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.
DHCP An abbreviation of Dynamic Host Configuration Protocol,
this protocol automatically assigns an IP address to equip‐
ment 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.
HDCP HDCP is an abbreviation for High-bandwidth Digital Con‐
tent Protection.
It is used to prevent illegal copying and protect copyrights
by encrypting digital signals sent over DVI and HDMI ports.
Because the HDMI port on this projector supports HDCP, it
can project digital images protected by HDCP technology.
However, the projector may not be able to project images
protected with updated or revised versions of HDCP en‐
cryption.
HDTV An abbreviation for High-Definition Television that refers to
high-definition systems which satisfy the following condi‐
tions:
• Vertical resolution of 720p or 1080i or greater (p =
Progressive, i = Interlace)
• Screen aspect ratio 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 send‐
ing 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.
IP Address A number to identify a computer connected to a network.
MHL An abbreviation for Mobile High-definition Link, a standard
for connection interfaces aimed at mobile devices such as
smartphones and tablets.
Images can be transferred at high quality and at high speeds
without compressing the digital signal, and also charges
connected devices.
