HD-SDI
High Definition Serial Data Interface
A serial communications interface operating at 1.5 Gbit/sec.
I/O
Input/Output
IP Address
An Internet Protocol (IP) address is a 32-bit number (for example,
123.45.67.89 for IP version 4) or a 128-bit number (for IP version 6) that
identifies the network device that is sending or receiving information that is
transmitted across a local area network (LAN) or the Internet.
LAN
Local Area Network
A network that provides data communications to users within a confined
geographic area such as a building or complex of buildings; TCP/IP is the
typical transport protocol.
LED
Light Emitting Diode
A semiconductor diode that converts electricity into visible light.
LNA
Low Noise Amplifier
Used in communication systems to amplify weak signals that are captured by
antennas.
LQ
Link Quality
A feature provided in MRC COFDM receivers that analyzes signal-to-noise
ratio and other important digital signal parameters as supplied by the COFDM
demodulator circuit. The Link Quality feature calculates an integer value from
0 (no signal) to 9 (highest possible quality).
MaxRC
Maximal Ratio Combining
A method of diversity combining that sums the IF/RF signals from the
antenna, according to their individual strengths to optimize performance.
MPEG
Moving Picture Experts Group
A working group of ISO that establishes standards for digital video and audio
compression.
Multipath
An unpredictable set of reflections and/or direct waves, each with its own
degree of attenuation and delay. Due to obstacles and reflectors in the
signal’s path, transmitted signals arrive at the receive antenna from various
directions over multiple paths at slightly different times.
MUX
Multiplexer
A device that is able to send several signals over a single line.
