Advanced Level Configuration (Template Checking Tests) (DVB/ATSC)
This template checking lets you check stream parameters not specified in
TR 101-290. This allows handling checking of non-DVB (or non-ATSC)
compliant streams.
Available in AMETH3-LIC-SWITCH-ADV.

Test Description
ASI 310M GigE Optional/Mandatory Duration Upper threshold Lower threshold
PID Maximum Bit Rate
(and PID Absence)
This test checks that a PID mean rate in a given period is
lower than the defined threshold.
Define the threshold in the Maximum bit rate field, in
kilobits per second.
You can also set the Measurement duration, in
milliseconds (lowest value: 500 ms). You may increase
this duration to allow punctual peaks.
This test may be used to verify the absence of a PID. For
example, to check that a PID never occurs, set the
maximum bit rate to 0. With this configuration, an alarm
will be raised if a transport packet is received.

PID Minimum Bit Rate
(and PID Presence)
This test checks that a PID rate is greater than a given
threshold.
Its configuration is similar to previous test.
This test may be used to verify the presence of a PID.
For example, to check that a PID occurs at least once by
10 seconds period:
Set the Minimum bit rate to 0.
Set the Measurement duration to 10.000 ms.
With this configuration, an alarm will be raised if no
transport packet was received for 10 seconds.
