•
PCR_repetition_error: The PCRs are used to re-generate the local 27 MHz system clock. If
the PCR do not arrive with sufficient regularity then this clock may jitter or drift. The
receiver/decoder may even go out of lock. This error indicates that the time interval between two
consecutive PCR values is more than 40 ms.
•
PCR_discontinuity_indicator_error: The PCR_discontinuity_indicator_error is set in the case
that a discontinuity of the PCR values occurs that has not been signalled appropriately by the
discontinuity indicator.
•
PCR_accuracy_error: The accuracy of ±500 ns is intended to be sufficient for the colour sub-
carrier to be synthesized from the system clock. This test should only be performed on a
constant bitrate TS as defined in ISO/IEC 13818-1.
•
PTS_error: The Presentation Time Stamps (PTS) should occur at least every 700 ms. The PTS
is only accessible if the TS is not scrambled.
•
CAT_error: The CAT is the pointer to enable the receiver to find the EMMs associated with the
CA system(s) that it uses. If the CAT is not present, the receiver is not able to receive
management messages.
