comprised of two fields of 262.5 lines each, running at an
effective rate of 30 frames per second.
 “PAL”: Phase Alternate Line. A television standard in which the
phase of the color carrier is alternated from line to line. It takes
four full pictures (8 fields) for the color-to-horizontal phase
relationship to return to the reference point. This alternation
helps cancel out phase errors. For this reason, the hue control
is not needed on a PAL TV set. PAL, in many transmission
forms, is widely used in Western Europe, Australia, Africa, the
Middle East, and Micronesia. PAL uses 625-line, 50-filed (25
fps) composite color transmission system.
 “Operator”:
Refers to the person who uses the system.
 “PIP”: Picture-in-Picture. A small picture within a larger picture
created by scaling down one of the images to make it smaller.
Each picture requires a separate video source such as a
camera, VCR, or computer. Other forms of PIP displays include
Picture-by-Picture (PBP) and Picture-with-Picture (PWP),
which are commonly used with 16:9 aspect display devices.
PBP and PWP image formats require a separate scaler for each
video window.
 “Polarity”: The positive and negative orientation of a signal.
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.
