FBAS
Colour-picture-blanking-synchronous signal for
the transmission of colour video signals
FEC
FEC is the abbreviation for Forward Error
Correction. 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 corresponds 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.

MPEG-2
MPEG is the abbreviation for “Moving Picture
Experts Group”, a working group that formulates
internationally applicable standards for the

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.
NAS
