HE4000 Encoding System
K
kbps
Kilobits per second. A ratio of 1000 bits transmitted per second. For example,
10 kbps is equal to 10,000 bits transmitted per second.
Kbps
Kilobytes per second. A ratio of 1000 bytes transmitted per second. For
example, 10 Kbps is equal to 10,000 bytes transmitted per second.
kg
Kilogram
kHz
Kilohertz
Ksps
Kilosample or kilosymbol per second. A ratio of 1000 samples or symbols
transmitted per second. For example, 10 Ksps is equal to 10,000 samples or
symbols transmitted per second.
Ku-Band
A portion of the electromagnetic spectrum in the 12 GHz to 14 GHz range. Used
for satellites, employing 14 GHz on the uplink and 11 GHz on the downlink in
support of such applications as broadcast TV for man-on-the street interviews
and other situations requiring a small, portable dish. Ku is also used in Direct
Broadcast Satellite (DBS) systems, or Direct Satellite System (DSS).
L
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.
Line
Resolution
The degree of sharpness of a displayed video image.
LNB
Low Noise Block. A combination low noise amplifier and local oscillator used in
some satellite downconverters.
LO
Local Oscillator. A device within a frequency converter that is used to reduce or
increase the frequency of the signal passed from the device input to output.
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.
