Transport Stream Monitoring
The Transport Stream Monitoring (TSM) option analyses the demodulated transport stream
output of the input RF signal.
TSM can be used for confidence monitoring at transmitter relay sites, amongst other
applications. TSM is especially useful for detecting that Transmitter Re-Broadcast Links (RBL)
sites are operating correctly.
TSM works identically for transport streams generated either by DVB-T or DVB-T2.
TSM can detect the presence of the Programme Association Table (PAT) and up to six-
programmed Packet Id’s (PID’s). PAT and PID’s presence is checked against programmable
upper distance times.
If PAT or PID is missing for a user programmed time period, an alarm is generated. This alarm
is stored in the log, displayed in the Web page GUI and the SNMP MIB is updated. PAT and PID
alarms are separately stored in the Log.
TSM is configured and monitored using either the Web based interface or using the MIB.
Transport Sync alarm (see DVB-T/T2 Configuration) must be enabled for TS monitoring to
operate.
