88 - Terminology

Terminology

This section provides simple explanations for the terminology used within the manual, items

for which explanations are not available, and other complex processes.

A/V Mute Temporarily erases the image and sound at the same time. The sound and image

can be muted by pressing the [A/V Mute] button on the projector. Press the [A/V

Mute] button once again or adjust the volume or display the menu to cancel the

mute mode.

Color differential signal Video equipment transmits signals through three cables as Red-Bright (R-Y),

Bright (Y) and Blue-Bright (B-Y). This enables the composite signals (the red, green

and blue signals and their brightness signals are transmitted along one cable) to be

projected more clearly.

Cool-down A lamp cooling procedure continues to operate even after the power supply has

been switched off and the lamp extinguished. The cooling fan will begin to operate

when the lamp is entinguished, and button operations will not longer be possible.

This period is known as the cooling down period. The amount of time required for

the cooling down procedure will differ in accordance with the surrounding tem-

perature.

Color temperature The temperature of the subject that emits light. A blue hue is attained when the

color temperature is high, and a red hue is attained when the color temperature is

low.

Contrast By strengthening or weakening the tone of the colors, it is possible to project char-

acters and pictures more clearly and attain a softer tint. This is known as contrast

adjustment.

DVI-D port The input port that conforms to the DVI digital video ratings (Digital Visual Inter-

face: Ratings to govern how video signals are digitally transmitted). Synchroniza-

tion and tracking misalignments will not occur during transmission.

Operating system The software necessary to operate the computer.

Remote port The optional remote control receiver can be connected.

SRS The three-dimensional acoustic system. This enables wide and deep sound to be

listened to. These are adjusted with the [Space] (wide) and [Center] (deep) but-

tons.

Stack projection Refers to the simultaneous duplicate projection of images with the use of multiple

projectors in order to increase projection image brightness.

SVGA IBM PC/AT compatible (DOS/V equipment) signals with 800 horizontal pixels

and 600 vertical pixels.

SXGA IBM PC/AT compatible (DOS/V equipment) signals with 1,280 horizontal pixels

and 1,024 vertical pixels.

Synchronization (Sync) Outputs computer signals at a pre-determined frequency. The image will not be

projected clearly unless this frequency is aligned with the frequency of the projec-

tor. Aligning the signal phasing is known as synchronization. Projected images

will be subject to distrubance, blurring and horizontal noise if not synchronized.

Theft-protection lock A theft-proof cable (available on the open market) is passed through the holes on

the projector case to secure it to a desk or column. These holes support the Micro-

Saver Security System manufactuered by Kensington Inc.
