NTFS
File system for storage media
OSD – On-Screen Display
Displays by the receiver on the TV screen (e.g.
Mainmenu).
PAL
Analogue TV standard
Pay TV
Television channels available on subscription
(e.g. Sky). Encrypted channels which can be
decrypted only by using the appropriate
Smartcard. As a rule these services are
subscription-only.
PID
The PID (Packet Identifi cation) number is an
identifi cation number for video signals and audio
signals in the digital data stream of DVB-MPEG-2
signals. The receiver uses the PID number to
create a unique assignment for the video and
audio data transmission. The PCR PID is the
identifi
cation number for the synchronisation
signal. The PID PCR is normally identical to
the video PID. For programmes broadcast in
multiple languages, the audio PID can be entered
manually to assign a different language to the
TV programme. After the PID is entered, the
digital receiver automatically selects the audio
data identifi
ed by the PID number from the
data stream and assigns it to the video signal.
PIN
Personal Identifi
cation Number. For this unit
the PIN is a four-digit numeric code which must
be entered to unlock the unit to allow access to
certain functions and channels.
Polarisation
The individual transponders on satellites
transmit on two different (polarisation) planes
(horizontal and vertical). The capacity of the
transponder is increased as a result.
QPSK – Quadrature Phase Shift Keying
Digital modulation process that is used for
satellite transmission (8PSK is also used in
connection with HDTV).
Receivers
Receiver
RGB
Video signal made up of three individual colour
signals (red, green, blue)
SAT IF signal
Receiver input signal, satellite intermediate
frequency
Scart cable
21-pin connecting cable (e.g. receiver/TV set)
SCR single cable system - Satellite Channel
Router
The one cable system is used to distribute digital
Sat IF signals (including HDTV) and terrestrial
signals over a single cable to up to eight receivers.
There is no limit on the variety of channels, i.e.
the complete range of channels from one or
two satellites is transmitted. Switching and the
transponder selection are undertaken in the feed
system or in the matrix and are controlled by the
receiver using a special DiSEqC™ command
to EN 50494. Each receiver is allocated a fi xed
subscriber frequency via which it receives its
channels. A twin receiver requires two such
subscriber frequencies. The transponder selection
and conversion to the subscriber frequencies is
undertaken using special tuner modules, so-called
SCR (Satellite Channel Router), that are installed
in the feed system or in the matrix.
The Kathrein one cable system satisfi es the
single-cable standard in accordance with
EN 50494, i.e. all the components of a single-
cable system that satisfy this standard can be
installed in a satellite system.
Smartcard
Card from Pay-TV provider to decode its
channels.
Standard gateway
Is used as an interface between two networks or
computers that are linked via a router.
As a result it is possible to transmit data.
Standby
Standby mode
Streaming
Transmission of data (recordings) in real time.
