Short Technical Guide - Kathrein UFC 960sw Operating Manual

AC 3
Output for Dolby Digital signal
AV programme pos.
Preferred programme slot on TV set for external
connections such as Scart and HDMI
CAM – Conditional Access Module
Decryption decoder, which uses a smart card to
decrypt the encrypted radio and TV signals.
Channel package
The channel package for a digital transponder
normally includes several TV and radio channels.
Each channel package has a fi xed assignment
for the transponder transmission frequency, for
polarisation (horizontal or vertical), for the symbol
rate and for the Viterbi rate or error rate.
CI - Common Interface
Internationally standardised interface for CA
modules
Conditional Access (CA) system
Controls user access to services and programmes
which are encrypted for reasons of copyright or for
commercial reasons.
Data rate
Data bits transmitted per second. Is expressed in
kbit/s or Mbit/s. The higher the data rate the better
the quality of the transmitted signal.
Data reduction
Compression of video
Redundant information is discarded.
Dolby Digital 5.1
Dolby Digital is a sound transmission that allows
digital surround sound to be output on a home
cinema system.
DVB - Digital Video Broadcasting
DVB-C refers to the transmission method
(C = cable, S = satellite, T = terrestrial)
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.

and audio 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.
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
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 television with a resolution up to
5 times higher or fi ner 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), the doubled number of
scanning lines (increased from the currently
625 to 1,250) and digital sound quality.
H.264
Another designation for MPEG-4.
IP address
Internet Protocol Address (for automatic linking of
a PC/laptop into an existing network)
MPEG-2
MPEG is the abbreviation for Moving Picture
Experts Group, a working group that formulates
internationally applicable
digital compression
MPEG-2 has become
standard for compression of digital TV signals.
MPEG-2 works up to a data rate of 100 Mbit/s.
