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.
