The list of available parameters is presented in a form of a table divided into 3
columns. Each column corresponds to its priority (1st, 2nd or 3rd), according to ETSI TR
101 290. If the parameter is selected to be checked during the analysis it is marked with a
icon.
The following parameters of the first priority are available:
1) 1.1 TS sync loss. Loss of synchronization with the transport stream: two or more
packets in a row have the synchronization byte value different from 0x47. Restore
of synchronization registers when 5 MPEG packets in a row have a proper
synchronization byte;
2) 1.2 sync byte error. MPEG packet synchronization byte value is different from
0x47;
3) 1.3a PAT error 2. The repetition period of all sections with table_id=0x00 (PAT) in
PID=0x0000 exceeds the defined value (500 ms by default). Sections with
table_id different from 0x00 found in PID=0x0000. Scrambling_control_field is
different from 0x0 for PID=0x0000;
4) 1.4 Continuity count. Incorrect packets sequence order: the continuity_count
field value of two consecutive packets with the same PID differs by more than 1; a
packet with the same continuity_count field value for the PID appears more than
twice in a row
5) 1.5a PMT error 2. The repetition period of all sections with table_id=0x02 (PMT)
in PID specified in the program_map_pid of the PAT table exceeds the defined
value (500 ms by default). Scrambling_control_field is different from 0x0 for PID
specified in the program_map_PID of the PAT table;
6) 1.6 PID error. The repetition period of the MPEG packets of elementary streams
(video, audio, data) exceeds the defined limit (5 sec by default). Elementary
streams of audio and data with a language descriptor of ISO 639 type, that is
different from 0, are excluded from checking.
The following parameters of the second priority are available:
1) 2.1 Transport error. Transport_error_indicator field of the MPEG packet equal to
1. This indicates that the packet is damaged and cannot be further analyzed;
2) 2.2 CRC error. The CRC error was detected in the CAT, PAT, PMT, NIT, EIT,
BAT, SDT or TOT table sections. This indicates that the table section is damaged
and should not be used by the receiver;
3) 2.3a PCR repetition. The repetition period of the PCR timestamps exceeds the
defined limit (40 ms by default);
4) 2.3b PCR discontinuity. The difference between the two consecutive PCR
timestamps counter values (PCR
