Polarity usually refers to the direction or a level with respect to
a reference (e.g. positive sync polarity means that sync occurs
when the signal is going in the positive direction).
 “RJ-45”: Registered Jack-45. A connector similar to a
telephone connector that holds up to eight wires used for
connecting Ethernet devices.
 ―RS-232”: An Electronic Industries Association (EIA) serial
digital interface standard specifying the characteristics of the
communication path between two devices using either DB-9 or
DB-25 connectors. This standard is used for relatively
short-range communication and does not specify balanced
control lines. RS-232 is a serial control standard with a set
number of conductors, data rate, word length, and type of
connector to be used. The standard specifies component
connection standards with regard to the computer interface. It
is also called RS-232-C, which is the third version of the
RS-232 standard, and is functionally identical to the CCITT
V.24 standard.
 “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
