Term/Acronym Definition
Analog Technology
in
which
a wave is recorded or used in its original form,
as opposed to digital. See Digital.
Bandwidth
A range of frequencies between two defined points expressed in
cycles per second, or hertz (Hz) when defining the circuit, or
kilobits per seconds or megabits per second (Mbps) for a
transmission line’s capacity, or the capacity of a transmission
channel for carrying information.
Binary
A base 2 number system used in programming computers
Bit rate
Sets the video default streaming bit-rate when the user connects
to the units and streams video.
Brightness
A description of how bright or dark the color appears in terms
of how much light is reflected back to the eye. Adding black
lowers its value, while adding white increases the value.
CATV Cable
TV
Central Processor Unit
(CPU)
Components of a computer that interprets and executes
instructions.
Contrast
The difference in brightness between different parts of an
image. If there is a little difference, the image has low contrast.
If there is a large difference, the image has high contrast.
Digital
Technology in which an analog wave is sampled at some
interval, and then turned into numbers that are stored in the
digital device
DVD
Digital Versatile Disc or Digital Video Disc
,
a type of optical
disk technology, commonly used as a medium for digital
representation of movies and other multimedia formats that
combine sound and graphics.
Ethernet
The most widely-installed Local Area Network (LAN)
technology. Ethernet networks operate at 10Mbps running over
coaxial cable or twisted pair wires (TP).
Hue
A description of the absolute place of color on the spectrum
according to its wavelength. In the visible spectrum from
infrared to ultraviolet, orange-red has a long wavelength
compared to indigo which has a shorter wavelength.
Input format
See NTSC.
Input filter mode
Sets the noise filter mode. A higher filter smoothes the image
(i.e., removes sharp edges and noises). This allows for greater
compressions at the expense of a less sharp image. A low filet
setting retains image detail and the expense of less compression.
Normally the unit is set to medium. If none is selected, the
codec simply passes the noise through to the image.
