In the head-end station display, the channel strips of the cassette are indicated
with “
Bx …A ” (“ Tuner A ”) or “ Bx …B ” (“ Tuner B ”). The channel strip “ Tuner A ”
can decode encoded services via a corresponding CA module and a dedicated
smart card. The cassette is programmed using the head-end station control unit.
Two LEDs in the channel strips provide an indication with their colour whether
an HF signal is present or not. In a menu, the transmission of DVB service in-
formation (EIT, TDT and SDT) or teletext (TXT) can be individually activated or
deactivated.
DVB service information:
EIT (Event Information Table):
For each service, event information is transmitted (such as starting time,
duration, encryption etc.)
TDT (Time Date Table):
The transmitted table contains the current time and date.
SDT (Service Description Table):
Information relating to the encryption is also sent with the name of each
service.
The LEDs for the LAN interface show whether a network connection exists and
whether a data transfer is in progress.
When the head-end station is switched on, the two-line LC display shows the
