the extent to which a given color in any image is free from white.
The less white in a color, the truer the color or the greater its
saturation. On a display device, the color control adjusts the
saturation. Not to be confused with the brightness, saturation is
the amount of pigment in a color, and not the intensity. Low
saturation is like adding white to the color. For example, a
low-saturated red looks pink.
 "Scaling": A conversion of a video or computer graphic signal from
a starting resolution to a new resolution. Scaling from one
resolution to another is typically done to optimize the signal for
input to an image processor, transmission path or to improve its
quality when presented on a particular display.
 "SDI": Serial Digital Interface. The standard based on a 270 Mbps
transfer rate. This is a 10-bit, scrambled, polarity independent
interface with common scrambling for both component ITU-R 601
and composite digital video and four channels of (embedded)
digital audio.
 "Seamless Switching": A feature found on many video switchers.
This feature causes the switcher to wait until the vertical interval
to switch. This avoid a glitch (temporary scrambling) which
normally is seen when switching between sources.
 "SMPTE": Society of Motion Picture and Television Engineers. A
global organization, based in the United States, that sets standards
for baseband visual communications. This includes film as well as
video and television standards.
 "S-Video": A composite video signal separated into the luma ("Y" is
for luma, or black and white information; brightness) and the
chroma ("C" is an abbreviation for chroma, or color information).
