Ceiling mount bracket
DLP™ technology

This is the mounting hardware used when hanging this unit

from the ceiling. Two types of ceiling mount bracket (low

the ceiling. These mounts are optional.

Component video signal

This signal is sent with its luminance signal and color signal independent. It creates higher image quality compared with an ordinary composite video signal because it bypasses the mixing and separating circuits. This signal is sent in three lines: the luminance signal (Y) and two color difference signals (PB/CB, PR/CR).

S video signal

S stands for Separate. This signal is sent with its luminance signal (Y) and color signal (C) separately. A 4-pin mini DIN connector and cable are used 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 signal is widely used for sending and receiving color images between computers. Horizontal and vertical sync signals are also necessary.

Dconnector

*This connector is designed for the Japanese D format only. This connector 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 perfor- mance characteristics. This unit is compatible with D1, 2, 3 and 4.

DVI connector

A digital RGB signal is sent from a computer to this connector differencially. A 24-pin connector and cable are used for connection.

Standby

The state under 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 to adjust the position and focus of the projected image on the screen.

Aspect ratio (aspect)

This basically means the length-to-width ratio of an image. This unit’s menu deals with two kinds of aspect ratio: the screen aspect that sets the length-to-width ratio of the screen to be used, and the display aspect that changes the size and aspect ratio of the images to be projected for different types of input signal.

Interlace

The common type of scanning for most televisions. It divides into two fields: even and odd numbered lines of the field to build one frame of an image.

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 by progressive scanning.

Key stone

If this unit has an elevation or depression angle when projecting on the screen, the image is distorted in a trapezoid. This item electrically corrects the distortion. Two types of correction are available; “Normal correction” and “Full correction”.

Letter box

This is the method to convert the content of a film in landscape orientation to 4:3 signal. It is possible to watch the landscape image without trimming by adding a black bar on the top and bottom of the screen. Vertical resolution may be sacrificed to some extent.

Squeeze

This method horizontally squeezes the film so that the aspect ratio is 4:3 when recording the film on a video medium. The squeezed image must be passed through the desqueezing circuit otherwise the image remains in a slender shape.

Vista size

One of the film sizes. The aspect ratio is 1.85:1 in North America and 1.66:1 in Europe.

Cinema scope size

This is the widest film size that uses a 70 mm film. The aspect ratio is 2.35:1.
