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.
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.
DHCP An abbreviation of Dynamic Host Configuration Protocol, this
protocol automatically assigns an IP address 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.
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.
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
encryption.
HDMI
An abbreviation for High Definition Multimedia Interface.
HDMI
is a standard aimed at digital consumer electronics and
computers. This is the standard by which HD images and
multichannel audio signals are digitally transmitted.
By not compressing the digital signal, the image can be
transferred at the highest quality possible. It also provides an
encryption function for the digital signal.
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
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.
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.
Progressive Projects information to create one screen at a time, displaying
the image for one frame.
Even though the number of scan lines is the same, the amount
of flicker in images decreases because the volume of
information has doubled compared with an interlace system.
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).
