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. HDCP should be used in
Europe for HDTV standard transmissions.
HDMI - High De fi nition Multimedia Interface
Digital interface for digital video and audio
data transmission (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/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 identi fi 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. mainmenu)
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 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.
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).
