Resolution Every video display device or video format has a
maximum number of Pixels that can be displayed.
This resolution is specified as the number of
horizontal pixels by the number of vertical pixels.
The resolution of a DVD is 720x480 for NTSC discs
and 720x576 for PAL discs. Scaling must be used to
convert this resolution to the resolution of a Fixed
Pixel display. The horizontal resolution of a CRT
(i.e., analog) is somewhat ambiguous, as there are no
discrete pixels used in this technology.
RGB RGB is short for Red-Green-Blue. The human eye
can visualize all colors from various combinations of
red, green, and blue light. All color video displays
use red, green, and blue to create color. Any signals
input to a color display device that are not in RGB
format must be converted to RGB before being sent
to the display element itself. Except for computer
monitors, most video display contain this circuitry
internally. When making an RGB connection to a
display device, synchronization (timing) signals are
also required. This can be accomplished either via
RGB+HV or SoG.
RGB+HV Red-Green-Blue + Horizontal-Vertical is one
method of transferring RGB video signals. In this
connection method, the horizontal and vertical sync
(timing) signals are separated from the video signals
themselves. Thus a total of five wires are required.
Scaling Scaling is the process of converting a video signal
from one Resolution to another. As with any type of
signal processing, care must be taken to ensure that
the signal is not degraded by the processing itself.
