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).

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 (PB/CB, PR/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.

DLPTM 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.

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.

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.

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.
