Elementary Stream
These streams contain only one MPEG video or audio channel.
Elementary streams are required if you intend to use Milestone or any player
that cannot operate with transport streams.
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.
