Terms and Definitions
The following terms and definitions are used throughout this
guide;
 “ASCII”: American Standard for Information Interchange. The
standard code consisting of 7-bit coded characters (8 bits
including parity check) used to exchange information between
data processing systems, data communication systems, and
associated equipment. The ASCII set contains control
characters and graphic characters.
 “Aspect ratio”: The relationship of the horizontal dimension to
the vertical dimension of an image. In viewing screens,
standard TV is 4:3, or 1.33:1; HDTV is 16:9, or 1.78:1.
Sometimes the ―:1‖ is implicit, making TV = 1.33 and HDTV =
1.78.
 “AV”: Audio visual or audio video.
 A “Background” is an unscaled source, typically originating
from a computer. A background source appears at the system’s
lowest priority — visually in back of all other sources.
 “Baudrate”：Named of J.M.E. Baudot, the inventor of the
Baudot telegraph code. The number of the electrical
oscillations per second, called baud rate. Related to, but not
the same as, transfer rate in bits per second (bps).
 “Blackburst”: The video waveform without the video elements.
It includes the vertical sync, horizontal sync, and the chroma
burst information. Blackburst is used to synchronize video
equipment to align the video output. One signal is normally
used to set up an entire video system or facility. Sometimes it
is called House sync.
 “BNC”: Bayonet Neill-Concel man. A cable connector used
extensively in television and named for its inventors. A
cylindrical bayonet connector that operates with a
twist-locking motion. To make the connection, align the two
curved grooves in the collar of the male connector with the two
projections on the outside of the female collar, push, and twist.
This allows the connector to lock into place without tools.
 “Brightness”: Usually refers to the amount or intensity of
video light produced on a screen without regard to color.
Sometimes called ―black level.
 ―CAT 5‖: Category 5. Describes the network cabling standard
that consists of four unshielded twisted pairs of copper wire
terminated by RJ-45 connectors. CAT 5 cabling supports data
rates up to 100 Mbps. CAT 5 is based on the EIA/TIA 568
Commercial Building Telecommunications Wiring Standard.
 “Color bars”: A standard test pattern of several basic colors
(white, yellow, cyan, green, magenta, red, blue, and black) as
a reference for system alignment and testing. In NTSC video,
the most commonly used color bars are the SMPTE standard
color bars. In PAL video, the most commonly used color bars
are eight full field bars. In the computer, the most commonly
used color bars are two rows of reversed color bars.
 “Color burst”: In color TV systems, a burst of sub-carrier
