Glossary

The following is a list of key words used in the use of projectors and image signals and their explanations. Please refer to it when using this

manual. For an explanation of vocabulary used in the menu, refer to "Menu group items and functions” ( ☞ page 30 - 37).

Reference

Ceiling mount bracket

The mounting hardware used to hang this unit from the ceiling.

Two types of bracket are available, for high and low ceilings.

Ceiling mount brackets are sold separately.

Cinemascope size

The widest film format in 70 mm film, with an aspect of 2.35:1.

Color spacing

The conversion of YUV color separated signal to RGB signal.

There are two formats for this, BT.601 for SDTV, and BT.709 for

HDTV. This unit switches between them as required.

Component video signal

A method of sending video signals with independent luminance

and color signals. Component video gives a higher image quality

than ordinary composite video because it bypasses mixing and

separating circuits. Component video signal consists of three lines,

the luminance signal (Y), and two color difference signals (P

B/CB,

R/CR).

Composite video signal

The most common type of video signal, combining luminance and

color signals in one line. This method requires mixing and

separating processes on both the send and receive sides. Use a pin

cable for connection.

DLP

technology

Digital Light Processing, an image display engine used in

projectors that use the DMD™ chip developed by Texas

Instruments.

DVI terminal

A digital RGB/Component signal is sent differently from a

computer or A/V equipment to this terminal. A 24-pin connector

and cable are used.

D terminal

A cable that allows transmission of all of the signals in composite

video in one cable. This method is used for transmitting image

signals between the latest AV components. There are 5 methods of

transmission, D1-D5. This unit is compatible with D4.

EDTV

Extended-Definition Television, a term used to define systems that

satisfy the following conditions:

•A resolution of 480p or 576p (p stands for progressive scans)

•A 4:3 or 16:9 aspect ratio

HDCP

A technique designed to protect the video transmission between a

DVI or HDMI transmitter and a display device.

HDMI

High-Definition Multimedia Interface, a method of differentially

transmitting digital RGB/component video signal from computers

and home digital equipment.

HDTV

High-Definition Television, a term used to define systems that

satisfy the following conditions:

•A vertical resolution of 720p or 1080i (p stands for progressive

scans, i stands for interlace scans)

•A 16:9 aspect ratio

Interlace

The most common type of scanning used in televisions. It divides a

screen into even and odd numbered fields for scanning, and then

builds an image by combining them into one image (frame).

Keystone Correction

Using the unit at an angle to the screen distorts the projected image

trapezoidally. You can use V Keystone Correction or H Keystone

Correction to electronically correct this distortion.

Letterbox

A method of converting the content of landscape oriented film to a

4:3 signal. You can watch landscape images without trimming them

by adding a black bar to the top and bottom of the screen, however

this sacrifices vertical resolution to some extent.

Progressive

A method of displaying all scanning lines in a frame at once,

reducing flicker noticeable on a larger screen and creating a sharp,

smooth image. This unit uses progressive scanning for progression.

RGB Signal

A method of transmitting color information using a numeric

representation of the primary colors red, green, and blue separately.

When received, it is expressed in various colors by adding a mixing

colors. RGB is widely used for sending and receiving color images

between computers, and requires horizontal and vertical sync

signals.

SDTV

Standard-Definition Television, a term used to define systems that

satisfy the following conditions:

•A resolution of 480i or 576i (i stands for interlace scans)

•A 4:3 or 16:9 aspect ratio

Smart zoom

Expands the left and right sides of a 4:3 image without altering the

center, when you are attempting to project a 4:3 image on a wide

screen format. This creates some distortion at both edges.

Squeeze

A method of compressing film images horizontally to an aspect of

ratio of 4:3 when recording to video medium. The raw image is

oblong, so needs to be passed through a desqueezing circuit to be

projected in it’s original form.

Standby

The state in which the circuit that receives infrared-signals from the

remote control is active, but all other main circuits are turned on.

The unit consumes a small amount of power in this state.

S Video signal

S stands for Separate. A method of sending signals with separate

luminance (Y) and color (C) signals. Use a 4-pin mini DIN

connector and cable for connection.
