Additional information

HDCP

High-bandwidth Digital Content Protection system. HDCP is designed to protect the video transmission between a DVI transmitter and a display device.

Aspect

This refers to the length-to-width ratio of an image.

Ceiling mount bracket

This is the mounting hardware used to hand this unit from the ceiling. Two types of bracket are available, for high and low ceilings. Ceiling mount brackets are sold separately.

Keystone

If the unit is used at an angle to the screen the projected image will be distorted in a trapezoid fashion. Keystone is used to electronically correct this distortion.

Letter box

This is a method used to convert the content of a film in landscape orientation to a 4:3 signal. It is possible to watch a landscape image without trimming by adding a black bar to the top and bottom of the screen, however this sacrifices vertical resolution to some extent.

Squeeze

This method compresses a film image horizontally to an aspect ratio of 4:3 when recording on a video medium. The squeezed image must pass through a de-squeezing circuit in order to be projected in it’s original form.

Smart Zoom

Smart zoom expands the left and right sides of a 4:3 image without altering the center, when it is necessary to project a 4:3 image to a wide screen format. This creates some distortion at both edges.

Vista size

A standard film size. The aspect ratio is 1.85:1 in North America and 1.66:1 in Europe.

Cinema scope size

The widest film format in 70mm film. The aspect ratio is 2.35:1.

Color spacing

This refers to the conversion of YUV color separated signal to RGB signal. There are two formats for this, SDTV BT.601 and HDTV BT.709. This unit can switch between them as required.
