The following values are provided:
Measurements Description
PCR Interval Measured interval time (in ms) between two consecutive PCR packets.
Repetition Error PCR repetition error.
Accuracy Error PCR Accuracy Error.
Min PCR_AC Minimum value of PCR accuracy value (nanoseconds) over the last
second.
Max PCR_AC Maximum PCR_accuracy value detected over the last second.
Min Peak PCR_AC Lowest PCR_accuracy value detected since last reset (with an initial
wait time of a few second).
Max Peak PCR_AC Highest PCR_accuracy value detected since last reset (with an initial
wait time of a few second).
Rate Offset Offset in ppm between the rate computed from the PCR values and the
actual rate. The actual rate is the measured rate in case of ASI inputs, or
the user-defined rate in case of TSoIP input.
Note: as the device clock has a precision of around 1
ppm, the rate offset is also an indication of the clock
offset between the source device (encoder or
multiplexor) and a true reference (with 1 ppm precision).
The rate offset is thus also an indicative measurement of
the PCR clock offset, while not being a formal
measurement of this value as defined in the standard.
PCR Rate Displays the current rate calculated from the PCR values in the
corresponding PID.
