SHORT TECHNICAL GUIDE
AC3
Output for Dolby Digital signal
ASTRA
SES (Société Européene des Satellites) satellite system. Analogue and digital transponders in the
frequency range 10.7-12.75 GHz.
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 and audio signals. Redundant information is discarded.
DiSEqC™
DiSEqC™ (Digital Satellite Equipment Control) is a communication system between a satellite receiver
(master) and the peripheral satellite components (slaves), such as LNBs, multi-switches, rotating antenna
systems.
It is a single master/multi-slave system, i.e. there is only ever one master in the satellite system. All activities
start from the master.
DiSEqC™ components
If DiSEqC™ switching matrices are cascaded, the master receiver must transmit the DiSEqC™ signal
several times, so that all DiSEqC™ multi-switches in the cascade receive their commands.
These days, DiSEqC™ components (slaves) must be reverse compatible, i.e. respond to the analogue
switching criteria from receivers that are only equipped with H/V and 22 kHz control signals.
A DiSEqC™ switching matrix will work with analogue switching criteria until the DiSEqC™ command from
the master is received. All analogue switching criteria are then ignored.
Dolby Digital 5.1
Dolby Digital is a sound transmission that allows digital surround sound to be output on a home cinema
system.
