■ Glossary

The following is a list of key words and their explanations used in

the use of projectors and image signals. Please refer to it when

using the DPX-1000.

DLP™ technology

This stands for Digital Light Processing. DLP uses the DMD

chip, developed by Texas Instruments.

DCDi™ function

This is an abbreviation of Directional Correlational

Deinterlacing, a high quality image circuitry developed by the

Faroudja company. It uses edge cutting techniques to remove

jagged edges from images during Interlace → Progressive

conversion, allowing smooth, natural image reproduction.

Component video signal

Component video signal is sent with independent luminance

and color signals. It gives a higher image quality than ordinary

composite video signal because it bypasses mixing and

separating circuits. Component video signal consists of three

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

B/CB, PR/CR).

S video signal

S stands for Separate. This signal is sent with separated

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

connector and cable for connection.

Composite video signal

This is the most common type of video signal. The luminance

signal and color signal are sent combined in one line. Mixing

and separating processes are necessary on both the send and

receive sides. A pin cable is used for connection.

RGB signal

An RGB signal transmits color information by using a numeric

representation of the primary colors of red, green and blue

separately. When the signal is received, it can be expressed in

various colors by adding and mixing colors. This type of signal

is widely used for sending and receiving color images between

computers. Horizontal and vertical sync signals are also

necessary.

HDTV

This is an abbreviation of 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).

• An image aspect ratio of 16:9

SDTV

An abbreviation of Standard Definition Television, used to

define normal television broadcasts which do not meet the

standards of HDTV.

Additional information

D connector

This connector is designed for the Japanese D format only.

It is used for sending and receiving the image signal between

the latest type of A/V components. This connector can receive

the component signal by using a D connector cable. There are

five levels (D1—D5) of performance characteristics. This unit

is compatible with D1, 2, 3, and 4.

DVI connector

A digital RGB/Component signal is sent differentially from a

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

connector and cable are used.

Standby

The state in which the circuit to receive infrared-signals from

the remote control is activated but other main circuits are

turned off. A small amount of power is consumed in this state.

Test pattern

Test patterns are stored in this unit for use in adjusting the

position and focus of the projected image on the screen.

Interlace

The most common type of scanning in use in televisions. It

divides an image into two fields for scanning, and uses even

and odd numbered lines of those fields to build an image

(frame).

Progressive

This displays all the scanning lines of the entire frame at one

time. It greatly reduces the flicker that is more noticeable on a

larger screen to create a sharp and smooth image. This unit

projects using progressive scanning.

3-2 Pulldown detection style IP conversion

A function for directly converting interlace signal into sixty

frame progressive signal used when receiving 60 field interlace

signal from an image source recorded with the same 24 frames

as movie film. This allows DVD and other materiel recorded

with 24 frames to be projected on large screens as a natural,

precise image with no loss of quality, comparable to a movie

film.

SYNC

Computers output signals with a given regular frequency,

which the projector must be synchronized to in order to

produce a good quality image. Failure to match the phase of the

signal will result in flickering, fading, and distortion of the

image.

TRACKING

Computers output signals with a given regular frequency,

which the projector must be synchronized to in order to

produce a good quality image. Failure to match signal

frequencies will result in vertical striping in the image.
