Aliasing
Distortion which occurs during sampling to convert analog signals to digital.
ATW

Color temperature
The color quality of light, expressed in Kelvin (K).
Reddish colors have a lower color temperature, and blueish colors a higher color temperature.
CRT
DCC
Abbreviation for dynamic contrast control. To provide a larger dynamic range for a video camera (the range of brightnesses of subjects that can be handled by the imaging device), the
SMPTE timecode runs at 30 frames/ second, while the NTSC color television system runs at about 29.97 frames/second.
EBU
