Short technical guide
HD – Ready
This is a label created by the EICTA (European
Information, Communications and Consumer
Electronics Industry Technology Association) for
equipment that is capable of reproducing HDTV.
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 De fi nition Multimedia Interface
Digital interface for digital video and audio data
transmission between TV and receiver (preferred
for HDTV).
HDTV – High De fi 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 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 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.
Polarization
The individual transponders on satellites transmit
on two different (polarisation) planes (horizontal
and vertical). As a result the capacity of the
transponder is increased.
