 “Saturation”: Chroma, chroma gain. The intensity of the color,
or 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 avoids 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 base band 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).
 “Sync”: Synchronization. In video, sync is a means of
controlling the timing of an event with respect to other events.
This is accomplished with timing pulses to insure that each
step in a process occurs at the correct time. For example,
horizontal sync determines exactly when to begin each
horizontal scan line. Vertical sync determines when the image
