Encoder
A processor in a video transmitter which changes analogue video from a
camera to digital data.
F

FEC
Forward Error Correction is a system of error control for data transmission,
whereby the sender adds redundant data to its messages, also known as an
error-correction code. This lets the receiver find and correct errors (inside
some bound) without the need to ask the sender for additional data. The
advantage of forward error correction is that a back-channel is not required,
or that retransmission of data can often be prevented, at the cost of higher
bandwidth requirements on average. FEC is thus applied in situations where
retransmissions are relatively costly or impossible.
Firmware
Software which is installed directly on a device and is intended specially for
that device and is used to control it.
FOV
Field of View - The field of view (also field of vision) is the angular quantity
of the observable world that is seen at a given moment.
Fading
A periodic decrease in the received signal strength.
Frequency
The rate at which a procedure repeats itself. In radio communications,
frequency is expressed in cycles for each second.
Signals also have a property called wavelength, which is inversely in
proportion to the frequency.
Frequency Modulation
Changing the frequency of a carrier wave, usually with an audio frequency, to
send intelligence. Also called FM.
FPGA
Field-Programmable Gate Array - an integrated circuit designed to be
configured by the customer or designer after manufacturing, hence "field-
programmable".
G
Means…
GUI
Graphical User Interface.
GHz
Gigahertz - One gigahertz is equal to 1,000 megahertz (MHz) or
1,000,000,000 Hz.
Gain
The increase in signal strength that is produced by an amplifier.
H
Means…
Hertz
One cycle for every second.
