Sync Byte Error (1.2) This test checks the statistics on synchronization byte
(0x47) errors.
This test detects synchronization byte errors even if they
are not contiguous (there is no loss of synchronization
in this case).
It is a complement of the
TS Sync Loss (1.1) test that cannot
detect this.
Enter a value in the
At least... unsynchronized packets
per second field.

PAT Interval (1.3.a.1) This test checks PAT periodicity, i.e. the intervals of each
section of the PAT.
An alarm is raised if the interval between 2 occurrences
of section 'x' of the PAT is greater than the value set in
the
Maximum period without PAT field, in milliseconds.
This test checks the first part of the test 1.3.a PAT_error_2
of TR 101 290.

PID 0 PAT (1.3.a.2) This test checks the Table Identifier (TID) of the sections
that are found on PID 0. The only TID that should be
found is 0 (PAT).
There are no specific parameters to set.
This test checks the second part of the test 1.3.a
PAT_error_2 of TR 101 290.

PAT Scrambling (1.3.a.3) This test checks that the PID 0 is not scrambled.
There are no specific parameters to set.
This test checks the third part of the test 1.3.a
PAT_error_2 of TR 101 290.

Continuity Counter (1.4) This test checks continuity counter errors on following
PIDs:

PSI: PIDs containing PAT (0x0), CAT (0x1), PMTs,
ECMs and EMMs.

SI (DVB version): PIDs containing NIT (0x10), SDT
(0x11), EIT (0x12), RST (0x13), TDT (0x14).

PSIP (ATSC version): base PID (0x1FFB) and PIDs
referred to by MGT.

Components: PIDs that contain program
components (e.g. video, audio, PCR).
There are no specific parameters to set.
