Appendix A: Glossary

NTSC Video

' A video output format of some video tape and disk players. There are two types of

 

NTSC (National Television Standards Committee) video: NTSC 3.58 and NTSC 4.43.

 

NTSC 3.58 is used primarily in North America and Japan. NTSC 4.43 is less

 

commonly used.

Optical Screen

' A type of rear-projection screen which re-directs light through the screen to increase

 

image brightness in front of the screen. Screen gain is usually greater than 1 but

 

audience viewing angles are reduced.

PAL Video

' PAL (Phase Alternating Line) video is a 50 Hz standard with 768 x 576 resolution. It

 

is found on some video tape and disk players (used primarily in Europe, China and

 

some South American and African countries).

Pixel

' The smallest discernible element of data from a computer-generated image.

Pixel Phase

' The phase of the pixel sampling clock relative to incoming data.

Pixel Tracking

' The frequency of the pixel sampling clock, indicated by the number of pixels per line.

Presentation Level

' The projector is at presentation level when an image from a source is displayed

 

without the presence of a slidebar, menu, pull-down list, or error message.

Projector-to-Screen

' The distance between the projector's front feet centers and the screen. Also called

Distance

"Throw Distance”.

Protocol

' The type of code format called “A” or “B” utilized by the remote keypad(s). The

 

default protocol set at manufacture is Protocol “A”. By using two different keypad

 

protocols, adjacent projectors can be controlled independently with their remote IR

 

keypads.

Pull-down List

' A selectable menu item that unfolds into a list of options pertaining to it.

QuVis

' A manufacturer of a digital video recorder/player/server, QuBit, frequently used for

 

providing digital cinema data. QuVis image compression uses a proprietary

 

technology called Quality Priority Encoding, based on wavelets, in which the user

 

selects a quality level based on signal-to-noise ratio. The data rate varies to efficiently

 

maintain that quality level. Frames are coded individually.

Rear Screen

' A translucent panel for screen projection. Incident light travels through the incident

 

surface of a rear screen and forms an image on the other surface.

Resizing

' The ability to manipulate through software commands the physical size, placement

 

and/or aspect ratio of an image.

Resolution (lens)

' The maximum number of alternate white and black horizontal lines that can be

 

distinguished on a screen when a photographic target is placed between the lens and a

 

light source and illuminated by that source.

Resolution (projector)

' The maximum number of pixels that the projector can display horizontally and

 

vertically across an image, such as 1024 x 768 (called XGA).

Retrace Time

' The minimum time required for a CRT projector to move the position of the scanning

(Horizontal)

spot from the right edge to the left edge.
