esCriPtion
The cassette converts services (programmes) modulated in DVB-S-/DVB-S2
standard into one outgoing COFDM modulated signal according to DIN EN
300744 for feeding into a cable network. The cassette has two SAT inputs and
one HF output. It is equipped with two channel strips ("
A " and " B ")
TPS
Tuner
A
Tuner B
CA Modul
Modulator HF Output
The channel strips are indicated in the head-end station display with " Bx …A "
and " Bx …B ". Using one adequate CA module scrambled stations of two trans-
ponders can be descrambled. The control of the cassette takes place via the
control unit of the head-end station.
Two LEDs provide an indication of the SAT IF input signal quality based on
their colour (only when stations are selected). Additionally the quality of the
transport stream received is displayed ("CN…"). The integrated TPS module
(Transport Stream Processing) processes the data of the transport streams.
The COFDM modulated HF output signals are sent through the HF output of the
cassette to the output collector. The common output level of the channel strips
can be set at the output collector.
Software update for the operating software of the cassette is possible via satellite.
