Short technical guide
HDCP – High-bandwidth Digital Content
Protection
Encryption system which protects the HDMI and
DVI interfaces for secure transmission of video
and audio data. HDCP should be used in Europe
for HDTV standard transmissions.
HDTV – High Defi nition Television
High resolution television with a resolution up to
5 times higher or fi ner than PAL or NTSC.
HDMI - High Defi nition Multimedia Interface
Digital interface for digital video and audio data
transmission (preferred for HDTV).
High band
Satellite frequency range between 11.7 GHz and
12.75 GHz.
H.264
Another designation for MPEG-4/AVC.
LNB - Low Noise Block Converter
Converts the satellite downlink frequencies into
the Sat-IF for the fi rst satellite.
Low band
Satellite frequency range between 10.7 GHz and
11.7 GHz.
MPEG-2
MPEG is the abbreviation for Moving Picture
Experts Group, a working group that formulates
internationally applicable standards for the
digital compression of video and audio.
MPEG-2 has become established as the
standard for compression of digital TV signals.
MPEG-2 works up to a data rate of 100 Mbit/s.
MPEG-4
A further development of MPEG-2 with even
higher data compression, intended for HDTV
transmissions.
NID
The channel identifi cation number is also
referred to as the Network ID or NID.
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 transmitters which can
only be decrypted by using the appropriate
smart card. As a rule these services are
subscription-only.
PCMCIA
Standard for internal decoder interface for pay-TV
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 synchronization signal. The
PID-PCR is normally identical to the video PID.
For programmes broadcast in multiple languages,
the audio PD 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 4-digit numeric code which must be
entered to unlock the unit to allow access to certain
functions and channels.
Channel Package
The channel package for a digital transponder
normally includes several TV and radio channels.
Each channel package has a fi xed assignment
for the transponder transmission frequency, for
polarisation (horizontal and vertical), for the symbol
rate and for the Viterbi rate or error rate.
QAM - Quadrature-Amplitude-Modulation
Digital modulation process with phase shift
keying, which is used for transmissions in cable
networks.
QPSK - Quadrature Phase Shift Keying
Digital modulation process that is used for satellite
transmission (8PSK is also used in connection
with HDTV).
Receivers
Satellite receiver
