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. Rarely used in cinema applications.
PAL (Phase Alternating Line) video is a 50 Hz standard with 768 x 576 resolution. It
is found on some video tape and disc players used primarily in Europe, China and
some South American and African countries.
Projector Configuration File, or Presentation Control File. A small file created by the
content owner or installer that controls the presentation of the elements and data
subdivisions constituting a single version of a title. The text component may identify
the name of the title, its owner, its length, event points, and other attributes. The PCF
specifies color space, target color gamut, gamma (a.k.a. "degamma"), aspect ratio
and image position settings. It does not include screen masking (cropping)
information. PCFs were originally intended as part of content distribution.
A distortion of the image shape characterized by concave edges.
The smallest discernible element of data in a digital image.
Pixel clock rate describes the speed at which incoming data is processed, and is
dependant on the native resolution and vertical frequency (such as 1280 x 1024 x
60Hz, or 2048 x 1080 x 24Hz) of the incoming source. The two processing paths
available in the projector—cinema vs. non-cinema—offer different maximum pixel
clock rates: 110 MHz if cinema path, and 165 MHz if non-cinema path, thus their use
with DVI sources depends on the incoming resolution and vertical frequency.
The phase of the pixel sampling clock relative to incoming data.
The frequency of the pixel sampling clock, indicated by the number of pixels per
line.
A small file or script typically created by the exhibitor or installer that specifies the
sequence of presentation of programs, including features and trailers.
The equipment in a digital cinema theatre which delivers previously recorded signals
in real time to the playback system. The playout may also receive, store, and process
these signals prior to delivering them.
The phase in film-making that occurs primarily after production ends; its processes
include picture editing, sound effects editing and mixing, ADR, Foley, titles and
opticals, dubbing and print mastering, CGI and visual effects, and scoring. Post
production culminates in acceptance of the original negative answer print. Even
though post production officially begins on the last day of principal photography,
post production facilities such as editing are utilized from very early in the
production phase in order to save time.
The area (in pixels, for digital images) that constitutes the entire motion picture frame
image. Compare: active picture.
The distance between the projector's front feet centers and the screen. Also called
"Throw Distance".
