Impedance
The total opposition of a device offers to the flow of
alternating current. Measured in ohms and varies at different
frequencies.
Integrated Receiver/Decoder
Within a satellite downlink system, a
piece of equipment used to demodulate and decode a transport
stream.
IRD
See Integrated Receiver/Decoder.
K
Ku –band
A portion of the electromagnetic spectrum in the 12GHz
to 14GHz range. Used for satellites, employing 14GHz on the uplink
and 11GHz on the downlink in support of such applications as
broadcast TV for man–on–thešstreet interviews and other situations
requiring a small, portable dish. Ku is also used in Direct Broadcast
Satellite (DBS) systems, or Direct Satellite System (DSS).
Kbps
Kilobits per second— A ratio of 1000 bits transmitted per
second. For example, 10Kbps is equal to 10,000 bits transmitted per
second.
KSps
Kilosample or kilosymbol per second—A ratio of 1000
samples or symbols transmitted per second. For example, 10KSps is
equal to 10,000 samples or symbols transmitted per second.
L
L–band
1. Portion of the electromagnetic spectrum commonly used
in satellite applications, with frequencies in the 390
MHz
to 1550
MHz
range.
2. For an IRD, the frequency received from the LNB, existing in a range
of 950
MHz
to 2050
MHz
.
LCD
Liquid crystal display—A display technology that uses
liquid crystals to form displayed characters.
LED
Light emitting diode—A display technology that uses a light
emitting diode to form displayed characters.
