2:2 pull-down
Theprocess of transferring 24-frames/sec film format into video by repeating each frame (used for PAL DVD’s) as two video fields.

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
allowframe-by-frame treatment and subsequently re-compose 3:2. The3:2 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 th e
editable point of the video sequence.

Chrominance
Thecolor co mponent of a video signal that includes information about tint and saturation.
DVI
DigitalVisual Interface is a display interface developed in response to the proliferation of digital flat panel displays.
Thedigital video connectivity standard that was developed by DDWG (Digital Display Work Group). Thisconnection standard offers
two different connectors: one with 24 pins that handles digital video signals only, and one with 29 pins that handles both digital
andanalog video. Thisstandard uses TMDS (Transition Minimized Differential Signal) from Silicon Image and DDC (Display Data
Channel) from VESA (Video Electronics Standards Association).
DVI can be single or dual link.
Luminance
The component of a videosignal that includes information about its brightness.
PiP
PiPstands for "Picture in Picture" and allows to display multiple windows containing each of them an image. Thewindows may be
of the video or data type.
