2.4 desCriPtion
The double transmodulator cassette is a converter, which converts COFDM
and QAM modulated signals into two COFDM modulated signals for feeding
into a cable network. The cassette has two RF inputs and one RF output. Addi-
tionally it is equipped with an ASI input and an ASI output (ASI – Asynchronous
Serial Interface according to EN 50083-9).
The transport stream fed via the ASI socket can be inserted into the transport
streams of the receiving stages via the TPS module. T he signal path is set in the
menu items input signal path "INROUTE" and output signal path "OUTROUTE" .

general
The cassette is equipped with two channel strips (" A " and " B "). The channel
strips consist of the DVB-T/-C tuners, the digital signal preparation units and the
output converter. The channel strips are indicated in the head-end station dis-
play with "Bx …A" and "Bx …B". Using an adequate CA module scrambled
channels can be descrambled via channel strip "A". The control of the cassette
takes place via the control unit of the head-end station.
Two LEDs provide an indication of the input signal quality based on their col-
our and indicate if the respective channel strip is switched on (LED illuminates)
or off. During the boot process both LEDs are blinking.
The integrated TPS module (Transport Stream Processing) processes the data
of the transport streams.
The COFDM modulated RF output signals are sent through the RF output of
the cassette to the RF output collector. The common output level of the channel
strips can be set at the output collector. Additionally a transport stream is made
available via the ASI output dependent on the signal path set.
When the head-end station is switched on, the two-line LC display shows the
software version of the control unit. To operate this cassette the software ver-
sion of the control unit must be "V 44" or higher. You can find the current op-
erating software for the control unit and the cassette, the software "BE-Flash"
and the current assembly instructions on the website "www.gss.de".
The cassette is intended for use in the STANDARD LINE head-end stations.

2.6 how the tPs module works
After decoding COFDM or QAM-modulated signals, the demodulated data
streams and the data stream fed via the ASI socket can be accessed via the
integrated TPS module. These data streams, also called transport streams,
contain several stations in all their components (video, audio, data and service
information), which can be changed using the TPS module.
station filter
Individual stations can be deleted. This reduces the data rate and, conse-
quently, the output symbol rate. Additionally stations of the different transport
streams can be assembled to a new transport stream.
stuffing
 Thetransportstreamispaddedusingwhatisknownaszerodata.Thisensures
a steady and constant output data rate.
Changing the tr ansPort stream and orgnet-id
The transport stream ID can be changed. If the stations of a transponder are
split into the transport streams of the channel strips "A" and "B", one of the
both transport streams a new identification must be allocated to realise the
channel search of the settop boxes connected without mistakes.
If the ORGNET-ID is changed a new NIT must be generated.
Changing the nit
The transport stream contains data in the form of tables which the receiv-
ers evaluate and require for convenient use. The TPS module can adjust the
"Network Information Table" (NIT) to accommodate the new station data. The
"NIT" contains data which is required by the set-top boxes connected to the
cable network for the automatic search feature.
Changing the oPer ator id (Cat)
Some network operators transmit an operator ID in the data stream (e.g.
visAvision). By changing the CAT the operator ID can be adjusted to the cur-
rent demands.
