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.
HDMI - High Defi nition Multimedia Interface
Digital interface for digital video and audio data
transmission between TV and receiver (preferred
for HDTV).
HDTV – High Defi nition Television
High resolution television with a resolution up to
5 times higher or
fi ner than PAL or NTSC.
High band
Satellite frequency range between 11.7 GHz and
12.75 GHz.
H.264
Another designation for MPEG-4.
JPEG - Joint Photographic Experts Group
Image compression technique.
Linux
Operating system
LNB - Low Noise Block Converter
Converts the satellite downlink frequencies into
the Sat-IF.
Low band
Satellite frequency range between 10.7 GHz and
11.7 GHz.
MP3
File format for compressed audio fi les
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.
NIT
The channel identi fi cation number is also
referred to as the Network ID or NIT.
NTFS
File system for storage media
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
be decrypted only by using the appropriate
smart card. As a rule these services are
subscription-only.
PID
The PID (Packet IDenti fi cation) number is an
identi fi 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 identi
fi cation number for the synchronisation
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 identi
fi ed by the PID number from the data
stream and assigns it to the video signal.
PIN
Personal Identi fi 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.
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).
