Definition
Encoder
A processor in a transmitter that converts video or audio to compressed
digital signals.
F
Definition
FEC
Forward Error Correction is a system of error control for data transmission,
whereby the sender adds redundant data to its messages. This allows the
receiver to detect and correct errors without the need to ask the sender for
additional data.
FPGA
A Field-Programmable Gate Array is an integrated circuit that can be
programmed to perform complex logic functions.
G
Definition
Gain
An increase in signal strength, typically by an amplifier.
GUI
A Graphical User Interface allows users to interact with an electronic
device.
I
Definition
IP address
An Internet Protocol address is a unique numeric ID for a device within a
network.
L
Definition
LOS
Line-of-sight propagation refers to RF transmissions that travel in a direct
path from transmitter to receiver.
M
Definition
MPEG
Moving Pictures Experts Group is an organisation that sets the standards
for audio and video compression and transmission.
Modulation
To change the output of a transmitter in amplitude, phase or frequency in
accordance with the information to be transmitted. Data is superimposed on
a carrier current or wave by means of a process called modulation.
Multicast
Multicasting is sending data from a sender to multiple receivers where each
receiver signals that they want to receive the data.
N
Definition
NLOS
Non-line-of-sight propagation refers to RF transmissions that travel in a
path obstructed by physical objects.
