A TR 101 290 measurement indicator.

#[non_exhaustive] — additional Priority-3 variants may be added later.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

TsSyncLoss

TR 101 290 v1.4.1 Table 5.0a indicator 1.1 — loss of synchronisation with hysteresis.

SyncByteError

TR 101 290 v1.4.1 Table 5.0a indicator 1.2 — sync_byte not equal 0x47.

PatError2

TR 101 290 v1.4.1 Table 5.0a indicator 1.3.a — PAT_error_2.

ContinuityCountError

TR 101 290 v1.4.1 Table 5.0a indicator 1.4 — Continuity_count_error.

PmtError2

TR 101 290 v1.4.1 Table 5.0a indicator 1.5.a — PMT_error_2.

PidError

TR 101 290 v1.4.1 Table 5.0a indicator 1.6 — PID_error.

TransportError

TR 101 290 v1.4.1 Table 5.0b indicator 2.1 — Transport_error.

CrcError

TR 101 290 v1.4.1 Table 5.0b indicator 2.2 — CRC_error.

PcrRepetitionError

TR 101 290 v1.4.1 Table 5.0b indicator 2.3a — PCR_repetition_error.

PcrDiscontinuityError

TR 101 290 v1.4.1 Table 5.0b indicator 2.3b — PCR_discontinuity_indicator_error.

PtsError

TR 101 290 v1.4.1 Table 5.0b indicator 2.5 — PTS_error.

CatError

TR 101 290 v1.4.1 Table 5.0b indicator 2.6 — CAT_error.

NitError

TR 101 290 v1.4.1 Table 5.0c indicator 3.1 — NIT_error (bad table_id on PID 0x0010 + NIT_actual absence; the 25 ms min-gap dimension of 3.1.a is deferred).

SiRepetitionError

TR 101 290 v1.4.1 Table 5.0c indicator 3.2 — SI_repetition_error (maximum interval dimension; minimum-gap deferred).

UnreferencedPid

TR 101 290 v1.4.1 Table 5.0c indicator 3.4 — Unreferenced_PID: a PID persists longer than the presence threshold without being referenced by the PAT/CAT/a PMT or one of the well-known SI PIDs.

SdtError

TR 101 290 v1.4.1 Table 5.0c indicator 3.5 — SDT_error (bad table_id on PID 0x0011 + SDT_actual absence; the 25 ms min-gap dimension of 3.5.a is deferred).

EitError

TR 101 290 v1.4.1 Table 5.0c indicator 3.6 — EIT_error (bad table_id on PID 0x0012 + EIT P/F actual absence; the 25 ms min-gap dimension of 3.6.a and the P/F pairing check 3.6.c are deferred).

RstError

TR 101 290 v1.4.1 Table 5.0c indicator 3.7 — RST_error (bad table_id on PID 0x0013; the 25 ms min-gap dimension is deferred).

TdtError

TR 101 290 v1.4.1 Table 5.0c indicator 3.8 — TDT_error (bad table_id on PID 0x0014 + TDT absence; the 25 ms min-gap dimension is deferred).

PcrAccuracyError

TR 101 290 v1.4.1 Table 5.0b indicator 2.4 — PCR_accuracy_error.

Not implemented: requires hardware arrival timing with ±500 ns resolution (ISO/IEC 13818-1 §2.4.2.2). A packet-index-derived arrival estimate cannot honestly resolve 500 ns, and a false positive is worse than a gap (c.f. the withdrawn PtsCheck). This variant exists for documentation completeness only and is never emitted by the monitor.

BufferError

TR 101 290 v1.4.1 Table 5.0c indicator 3.3 — Buffer_error.

Currently checks TB_buffering_error (overflow of transport buffer TBn, 512 bytes per ISO/IEC 13818-1 §2.4.2.3) and TBsys_buffering_error (overflow of TBsys, 512 bytes). The remaining sub-checks — MB_buffering_error, EB_buffering_error, B_buffering_error, Bsys_buffering_error — require codec-dependent buffer sizes from descriptors (multiplex_buffer_descriptor, smoothing_buffer_descriptor) and are deferred until the monitor parses those descriptors.

EmptyBufferError

TR 101 290 v1.4.1 Table 5.0c indicator 3.9 — Empty_buffer_error.

Checks that TBn (transport buffer for each elementary stream) and TBsys (system-information transport buffer) are empty at least once per second. The MBn check (multiplexing buffer, leak method) is deferred — it requires the full MBn buffer model with leak-rate parameters from descriptors.

DataDelayError

TR 101 290 v1.4.1 Table 5.0c indicator 3.10 — Data_delay_error.

Checks that data delay through the T-STD transport buffers (TBn, TBsys) does not exceed 1 second (60 s for still-picture video). The full end-to-end delay through MBn/EBn/Bn is not modelled (deferred — see Buffer_error doc).
