Decombining Streams
To decombine a transport stream from a combined stream, you need to know the CT
PID of the transport stream you want to decombine and the input (source) port that
the stream is received on the MTR.

the stream is received on the MTR.
All combined DVB-T transports within a single DVB-S/S2 carrier utilize a common
session word (key). To simplify key management, a table of up to 512 even/odd
keys is supported within the MTR. During installation, each DCM/DTF is
configured to transmit a table identifying the index which corresponds to the key in
use on that DCM/DTF. When a key is changed, the index within the applicable table
is also changed. Keys can be renewed by on-site entry or via SNMP.

Although transmission of the key index is part of inband data, the applicable table is
not part of the IBCC function. Therefore, failure or absence of the IBCC shall not
affect MTR key selection for descrambling purposes.

If the applicable table identifying the descrambling key is not found, then the MTR
will use the last known, good index and generate a warning. If the applicable table is
not found and no key can be identified, then the MTR will generate an alarm if the
selected transports on the selected carrier are scrambled.

The following parameters are necessary to decombine a transport stream from a
combined stream:
combined stream:
CT PID of stream to decombine
Source port, i.e., RF1, RF2, RF3, RF4, or ASI
Routing Output, Inband Data - set to Ignore for local setup
Output Rate - set to Source rate
Format - set to Decombined
BISS Index and session words (available from your service provider)
