SHORT TECHNICAL GUIDE
DVB – Digital Video Broadcasting
DVB-S refers to the transmission method (S = satellite, C = cable, T = terrestrial).
DVB-S2
An enhanced DVB-S signal for HDTV with better quality.
Eb/No ratio
The Eb/No ratio is a measure of the signal to noise ratio of a digital signal. The value is not identical to the
C/N value familiar from analogue reception technology. At Eb/No values below 5 dB no reception is normally
possible.
EUTELSAT
European Satellite operator, based in Paris. Many orbit positions and European customers. Transponders in
the frequency range 10.7-12.75 GHz.
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.
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 Defi nition Multimedia Interface
Digital interface for digital video and audio data transmission (preferred for HDTV).
HDTV – High Defi nition Television
High-resolution TV with a resolution up to 6 times sharper than PAL or NTSC, however it is incompatible with
them, because the broadcasting uses the DVB-S2 transmission and the MPEG-4 compression .
The principal features of HDTV are the larger picture format (16:9), the doubled number of scanning lines
(currently 625, increased to 1,250) and digital sound quality.
High Band
Satellite frequency range between 11.7 GHz and 12.75 GHz.
H.264
Another designation for MPEG-4.
LNB – Low Noise Block Converter
Converts the satellite downlink frequencies to 1.Sat-IF.
Low Band
Satellite frequency range between 10.7 GHz and 11.7 GHz.
