6.14.2.1 Error Monitoring
The Error Monitoring accordion panel has three parameters:
• Continuity Count Error Threshold - Dictates how many CC errors may occur
within a sliding window in time, before an alarm is raised by the unit.
• Continuity Count Error Sampling Window - Sets the sliding window time
period for monitoring of CC errors.
• Maximum Valid PID Missing Period - This parameter sets a sliding window
time period for monitoring of missing PIDs. PIDs are sampled once per second
for their presence. If a PID is missing for the number of seconds as set in the
parameter, an alarm is raised. The alarm will only clear once the PID is present
for the number of seconds set in the parameter.
6.14.3 Limitations
The AVP 4000 will only monitor a maximum of 40 separate PIDs regardless of the
PID distribution across incoming transport streams and transcoded services.
