ATTACHMENT A - GLOSSARY OF TERMS

CA - Conditional Access – a coding system
used in order to protect transmitted data
against unauthorised
protected channels
subscribers.
CAM - Conditional Access Module – an
electronic device, usually fitted with card
slots, that allows access to coded pay-per-
view channels on a receiver equipped with a
CI socket.
CI - Common Interface – CI sockets of
digital receivers are used for the installation of
CAM conditional access modules, and thus
allow you to view
channels through these modules.
DVB-S the Digital
standard that defines modulation and error
correction in satellite transmissions. In DVB-S,
both the MCPC and SCPC modes can be used
by the operator to transmit channels. MPEG-2
is used as the transport stream.
EPG - Electronic Programme Guide – a
service that displays detailed
about current and future programmes on the
television screen.
FTA - Free-to-air – uuencoded radio and
television channels that may be received on
any television set.
LNB - low-noise block converter – a
converter - it converts satellite signals, and
then sends them to the tuner through a
coaxial cable. The basic parameters are: gain,
noise factor and power consumption.
MCPC - multiple channels per carrier –
more than one signal (channel) is transmitted
on a given frequency (transponder). All of
these channels comprise a single data stream,
which is transmitted
following modulation.
Monoblock – a device that comprises two
converters and a DiSEqC switch in a single
housing, which receives signals from two
satellites on similar orbits.

Pay-TV – Pay-per-view digital television, to
which only subscribers have access. The

SCPC - Single channel per carrier – only one
to
signal (channel) is transmitted over a given
frequency (transponder).
STB - Set-top box – an electronic device
connected to
processes the
ground-based,
antenna. It enables the playback of video and
sound.
TP - Transponder – a type of wireless
communication device (transmitter), which
automatically
strengthens and responds to a signal coming
in real time over a specific frequency. The
term is derived from the words "transmitter"
and "responder". Usually, each transponder
transmits numerous
channels.
DiSEqC - (Digital Satellite Equipment
Control) a communication protocol, used
between a satellite receiver and equipment
such as switches
supports switching between television signal
sources and antenna control.
USALS – (Universal Satellites Automatic
Location System)
protocol used between satellite receivers and
positioners, which makes it possible to control
the positioner through the receiver. Used in
connection with the DiSEqC 1.2 protocol.
