Kathrein UFS 902 Eb/No ratio, HD Ready, Hdcp High-bandwidth Digital Content Protection, High band

SHORT TECHNICAL GLOSSARY

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

Scrambling 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 Definition Multimedia Interface

Digital interface for digital video and audio data transmission (preferred for HDTV).

HDTV – High Definition Television

High resolution television with a resolution 6 times higher or finer than PAL or NTSC. However, there is no compatibility, as the transmission process DVB-S2 and the compression technique MPEG-4 are used for broadcasting.

The principal features of HDTV are the larger picture format (16:9), twice the number of scan 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 1st Sat IF.

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 established itself 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.
