TERMINOLOGY
Blanking Level
The level separating the
SYNC
portion from the video portion
of the waveform. Usually referred to as the front porch or back
porch. At 0 IRE units, it is the level that will shut off the picture
tube, resulting in the blackest possible picture.
Color Video (RGB)
This usually refers to the technique of combining the three
primary colors of red, green, and blue to produce color pictures
within the usual spectrum. In RGB monitors, three DACs are
required, one for each color.
Sync Signal (
SYNC
)
The position of the composite video signal that synchronizes the
scanning process.
Grayscale
The discrete levels of video signal between reference black and
reference white levels. An 8-bit DAC contains 256 different levels.
Raster Scan
The most basic method of sweeping a CRT one line at a time to
generate and display images.
Reference Black Level
The maximum negative polarity amplitude of the video signal.
Reference White Level
The maximum positive polarity amplitude of the video signal.
Sync Level
The peak level of the
SYNC
signal.
Video Signal
The portion of the composite video signal that varies in grayscale
levels between reference white and reference black. Also referred
to as the picture signal, this is the portion that may be visually
observed.
