OSD - On-Screen Display

Displays by the receiver on the TV screen (e.g.

main menu)

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.

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). As a result the capacity of the

transponder is increased.

QPSK - Quadrature Phase Shift Keying

Digital modulation process that is used for satellite

transmission (8PSK is also used in connection

with HDTV).

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).

SCR single-cable system - Satellite Channel

Router

The single-cable system is used to distribute digital

Sat IF signals (including HDTV) and terrestrial

signals via one 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 single-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 decrypt 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
