Priority 3 Parameters
(1) NIT_actual_error: Network Information Tables (NIT) as defined by DVB, contain information on frequency,
code rates, modulation, polarization, etc. of various programs which the decoder can use. It is checked
whether the NIT related to the respective TS is present in this TS and whether it has the correct PID.
(2) NIT_other_error: Further NITs may be present under a separate PID and refer to other TSs to provide more
information on programs available on other channels. Their distribution is not mandatory and the checks
should only be performed if they are present.
(3) SI_repetition_error: For SI tables, a maximum and minimum periodicity are specified in EN 300 468 and TR
101 211 documents. This indicator should be set in addition to other indicators of repetition errors for
specific tables.
(4) Unreferenced_PID: Each non-private program data stream should have its PID listed in the PMTs.
(5) SDT_actual_error: The SDT (Service Description Table) describes the services available to the viewer. It is
split into sub-tables containing details of the contents of the current TS (mandatory) and other TS
(optional). Without the SDT, the receiver is unable to give the viewer a list of what services are available.
It is also possible to transmit a BAT on the same PID, which groups services by type.
(6) SDT_other_error: This check is only performed if the presence of a SDT for other TSs has been established.
(7) EIT_actual_error: The EIT (Event Information Table) describes what is on now and next on each service,
and optionally details the complete programming schedule. The EIT is divided into several sub-tables,
with only the "present and following" information for the current TS being mandatory. If there are no
'Present' or 'Following' events, empty EIT sections will be transmitted according to TR 101 211. The EIT
schedule information is only accessible if the TS is not scrambled.
(8) EIT_other_error: This check is only performed if the presence of an EIT for other TSs has been established.
(9) EIT_PF_error: If either section ('0' or '1') of each EIT P/F subtable is present, both should exist. Otherwise a
EIT_PF_error has occurred.
(10) RST_error: The RST is a quick updating mechanism for the status information carried in the EIT.
(11) TDT_error: The TDT carries the current UTC time and date information. In addition to the TDT, a TOT can
be transmitted which gives information about a local time offset in a given area.
The TR 101 290 Priority 1, 2 and 3 Tests Event List (above) lists information on each event, including the
number, timestamp, and error details.
