esCriPtion
The transmodulator cassette is a converter, which converts stations modulated
according to DVB-S / DVB-S2 standard into two COFDM-modulated signals ac-
cording to DIN EN 300744 for feeding into a cable network. The cassette has
one digital SAT IF input and one HF output.
g
ener al
The cassette is equipped with two channel strips (modulators "
A
" and "
B
").
The channel strips consist of the digital signal preparation units and the output
converter. The channel strips are indicated in the head-end station display with
"
Bx …A
" and "
Bx …B
". Using an adequate CA module encoded channels
can be decoded.
The control of the cassette takes place via the control unit of the head-end station.
A LED provides an indication of the SAT IF input signal quality based on its
colour and indicates if the channel strip A is switched on (LED illuminates) or
off. Additionally the quality of the transport stream received is displayed on
the display ("
CN…
"). The integrated TPS module (Transport Stream Process-
ing) processes the data of the transport streams.
