This appendix defines the specific terms used in this manual as they apply to this
projector. Also included are other general terms commonly used in the projection
industry.
A frame sequence used to map 24 fps film to 30 fps video (or 24/1.001 to 30/1.001
fps) in which every second film frame is represented by three video fields instead of
two, the third being a repeat of the second. This leads to a set of ten video fields for
each four film frames.
The time, inside one horizontal scan line, during which video data is present.
The area of a video frame which carries image information. As an example, a total
frame size of 1125 x 2200 pixels may have an active picture of 1280 active lines and
1920 samples per active line. Compare to production aperture.
Non-cinema program material such as concerts, plays, sporting events, and
potentially corporate training or conferencing, presented in theatres in addition to
motion picture exhibition. Alternative content connects to one of the projector's DVI
ports.
The ability of a screen to reflect ambient light (i.e., light within a room from a source
other than the projector) in a direction away from the "line of best viewing". Curved
screens usually have better ambient light reflection than do flat screens.
Having or requiring a linear distortion, generally in the horizontal direction.
Anamorphic lenses restore a 'scope' (CinemaScope) or 'flat' format film frame to the
correct appearance by increasing its horizontal proportion. The CP2000 uses a 1.25x
scope anamorphic lens option only.
American National Standards Institute, the organization that denotes the
measurement standard for lamp brightness.
A print made from the cut original (camera) negative with proposed final color
timing and soundtracks, furnished by the printing lab to the producer for acceptance
of image and sound before screenings and manufacturing begin. A check print is
similar, but is made from the internegative. A blacktrack answer print has no
soundtracks.
The ratio of the width of an image to its height, such as the 4:3 aspect ratio common
in video output. Also expressed as decimal number, such as 1.77, 1.85 or 2.39. The
larger the decimal, the wider and "less square" the image.
