Configuration of ATSC Level 3
PID 0x1FFB (3.1) This test checks the Table Identifier (TID) of the sections
that are found on PID 0x1FFB. The only TIDs that should
be found are 0xC7, 0xC8, 0xC9, 0xCA, 0xCD, 0xD3, 0xD4
and 0x72.
There are no specific parameters to set.

STT Interval (3.3) This test checks the STT periodicity, i.e. the intervals of
the STT.
An alarm is raised if the interval between two
occurrences of the STT is greater than the value set in
the
Maximum period field, in milliseconds.

Unreferenced PIDs
(3.4.a) This test checks that there are no unexpected ghost
PIDs.
Unexpected ghost PIDs are PIDs that are different from:

PIDs between 0 and 0x1F,

PIDs referred by the PAT (PMT PIDs),

PIDs referred by PMTs (e.g. video, audio, PCR,
ECM),

PIDs referred by the CAT (EMM),

PIDs referred by the MGT,

PIDs that you consider as expected ghosts and
that you must set as such. To do so, click the
Add
private PID button and set the PID value in the
displayed field.
An alarm is raised if an unexpected ghost PID is present
during an amount of time greater than the duration
specified in the
Allowed duration without reference
field, in milliseconds

MGT Interval (3.5) This test checks the MGT periodicity, i.e. the intervals of
the MGT.
An alarm is raised if the interval between two
occurrences of the MGT is greater than the value set in
the
Maximum period field, in milliseconds.
