FEC
FEC is the abbreviation for Forward Error Correc-
tion. A technique for reducing the error rate of data
transmission. Additional bits are inserted into the
data stream so that error-correction algorithms
can be used on reception. The FEC error rate cor-
responds to the Viterbi rate.
FTP - File Transfer Protocol
File transfer method. FTP is a network protocol for
the transmission of
fi les via IP(Internet Protocol)
networks
GNU
GNU is not Unix, it is an open operating system for
software developers.
H.264

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
fi ve times higher or fi ner than PAL or NTSC.
High band
Satellite frequency range between 11.7 GHz and
12.75 GHz.
IP address
Internet Protocol address. Every unit that can be
used in a network has a dedicated IP address
so as to obtain an unambiguous assignment
(address) for e.g. the exchange of data.
JPEG - Joint Photographic Experts Group

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 digi-
tal compression of video and audio. MPEG-2 has
become established as the standard for compres-
sion 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
Network
Connection of several PCs that as a result can
communicate and exchange data
OSD – On-Screen Display
Displays by the receiver on the TV screen
(e.g. main menu)
PAL
