GLOSSARY
CA - Conditional Access - Encryption system
used to secure content and grant access only
to subscribers.
CAM - conditional access module - is an
electronic device, usually incorporating a slot
for a smart card, which equips a set-top box
with the appropriate hardware facility to view
conditional access content that has been
encrypted using a conditional access system.
CI - Common Interface - is the slot on a
digital television receiver into which a
conditional access module (CAM) may be
inserted for satellite television. A receiver with
a common interface allows the user to access
encrypted television broadcasts as opposed to
free-to-air (FTA) channels.
DVB-S
is the original Digital Video
Broadcasting forward error coding and
modulation standard for satellite television.
DVB-S is used in both MCPC and SCPC modes
for broadcast network feeds, as well as for
direct broadcast satellite services. The
transport stream delivered by DVB-S is
mandated as MPEG-2.
EPG - Electronic Programme Guide, also
known as an Interactive Programme Guide or
IPG, provides an on screen guide to channel
listings, programme information or pay per
view events.
FTA - Free-to-air - broadcasts that are sent
unencrypted and may be received via any
suitable receiver.
LNB - low-noise block converter - is used
in communications satellite (usually broadcast
satellite) reception. The LNB is usually fixed on
the satellite dish.
MCPC - multiple channels per carrier -
several subcarriers are combined into a single
bitstream before being modulated onto a
carrier transmitted from a single location to
one or more remote sites.
Monoblock LNB - is a unit consisting of two
LNBs and is designed to receive satellites
spaced close together.
Pay-TV - Pay television or Premium
Television
refers to subscription-based
television services, provided digital cable or
satellite, but also by digital terrestrial
methods.
SCPC - Single channel per carrier - refers
to using a single signal at a given frequency
and bandwidth.
STB - Set-top box - Receiver device that
processes an incoming signal from a satellite
dish, aerial, cable, network or telephone line.
TP - Transponder – One of the transmitters
on a satellite. A transponder transmits on a
particular frequency to which a set-top box
must tune to receive a signal. Typically each
transponder can carry multiple compressed
digital television channels.
DiSEqC - (Digital Satellite Equipment
Control) is a communication protocol for use
between a satellite receiver and a device such
as a multi-dish switch or a small dish antenna
rotor. It is compatible with the actuators used
to rotate large C band dishes if used with a
DiSEqC positioner.
USALS – (Universal Satellites Automatic
Location System) - is a satellite motor
protocol that automatically creates a list of
available satellite positions in a motorized
satellite dish setup. It is used in conjunction
with the DiSEqC 1.2 protocol.
