Section 1: Introduction
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).
PCF
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.
PINCUSHION
A distortion of the image shape characterized by concave edges.
PIXEL (PICTURE ELEMENT)
The smallest discernible element of data in a digital image.
PIXEL CLOCK RATE
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.
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.
PLAY LIST
A small file or script typically created by the exhibitor or installer that specifies the sequence of presentation of
programs, including features and trailers.
PLAYOUT
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.
POST PRODUCTION
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.
