GLOSSARY
The process of transferring 24-frames/sec film format into video by repeating each frame (used for PAL DVD’s) as two video fields.
( AD )
Method used to map the 24 fps of film onto the 30 fps (60 fields) or 25 fps (50 fields), so that one film frame occupies three video
fields, the next two, etc. It means the two fields of every other video frame come from different film frames making operations
such as rotoscoping impossible, and requiring care in editing. Some sophisticated equipment can unravel the 3:2 sequence to
allow frame-by-frame treatment and subsequently re-compose 3:2. The 3:2 sequence repeats every five video frames and four film
frames, the latter identified as A-D. Only film frame A is fully on a video frame and so exists at one time code only, making it the
editable point of the video sequence.
Undesirable elements or defects in a video picture. These may occur naturally in the video process and must be eliminated in
order to achieve a high-quality picture. Most common in analog are cross color and cross luminance. Most common in digital are
macroblocks, which resemble pixelation of the video image.
A color space is a mathematical representation for a color. For example, the RGB color space is based on a Cartesian coordinate
system.
Dynamic host configuration protocol
PiP stands for "Picture in Picture" and allows to display multiple windows containing each of them an image. The windows may be
of the video or data type.
Address installed in the projector to be individually controlled.
