After  decoding  the  satellite  signals,  the  demodulated  data  streams  can  be 
accessed via the integrated TPS module. These data streams, also called trans-
port streams, contain several stations with all their components (video, audio, 
data and service information), which can be changed using the TPS module.

Individual  stations  can  be  deleted.  This  reduces  the  data  rate  and,  conse-
quently, the output data rate.

The transport stream ID can be changed. If the stations of a transponder are 
split into the transport streams of different channel strips, a new identification 
must be allocated to the "new" transport streams to realise the channel search 
of the settop boxes connected without mistakes.

 

If the ORGNET-ID is changed a new NIT must be generated.

The transport stream contains data in the form of tables which the receivers 
evaluate and require for convenient use. The TPS module can adjust the "Net-
work Information Table" (NIT) to accommodate the new stations output data 
(incl. LCN). The "NIT" contains data which is required by the set-top boxes 
connected to the cable network for the automatic search feature.

i

nstallation

  –  Ensure the head-end station is mounted so it will not be able to vibrate. 

Avoid, for example, mounting the head-end station onto a lift shaft or any 
other wall or floor construction that vibrates in a similar way.

 

–  Before installing or changing a module, switch off the head-end station or 

unplug the power cable from the mains power socket.

  –  Take measures to protect against ESD!

 

•  Open the housing of the head-end station in accordance with the assembly 

instructions for the STC 160.
