GLOSSARY
2:2 pull-down
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 )
3:2 pull-down
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.
AGC
Automatic Gain Control: allows an automatic amplitude (gain) control of the incoming video signal
ANSI 73.11
American power plug to connect the power cord to the wall outlet.
Artefacts
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.
CEE7
European power plug to connect the power cord to the wall outlet.
Chrominance
The color component of a video signal that includes information about tint and saturation.
Common address
Default address. Projector will always execute the command coming from a RCU programmed with that common address.
Component Video
In Component Video the term component describes a number of elements that are needed to make up the video picture, these
components are PR/Y/PB. A composite video signal on the other hand contains all the information needed for the color picture in a
single channel of information
DMD
Digital Micromirror Device
DVI
Digital Visual Interface is a display interface developed in response to the proliferation of digital flat panel displays. It uses a high
speed serial interface with TMDS (Transition Minimized Differential Signaling) to send data to the display.
DVI can be single or dual link.
Luminance
The component of a video signal that includes information about its brightness.
PiP
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.
Projector address
Address installed in the projector to be individually controlled.
