module works
After decoding the input signals, the demodulated data streams can be ac-
cessed 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.

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

orgnet-id
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.

hanging 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.
