4.6.2. Misc. Template
•
TS ID Expected: Enter the value for the Transport Stream ID expected, enter zero to disable
the test. A trap will be sent if the card receives a stream with a different value.
Note: It is not possible to enter the TS ID as a Hex value.
Num PIDs Expected: Enter here the number of PIDs expected in the stream, enter zero to disable the
test. A trap will be sent if the number of PIDs within the stream increases or decreases.
4.6.3. Window Measurement
The window measurement values determine the interval at which each PID (within the PID List
Template) should be expected before an alarm condition is met.
o Window Measurement 1 (ms): Enter a decimal value, measurement is in milliseconds
o Window Measurement 2 (ms): Enter a decimal value, measurement is in milliseconds
o Window Measurement 3 (s): Enter a decimal value, measurement is in seconds
•
PID List Template: The PID List Template provides a stream conformance or validation check
with the capability of alarming based on the status of each individual PID in the stream. Here
we can check the presence of each PID using one of the Window measurements as a detailed
above. Depending upon the importance of the PID we can selectively send an alarm if a PID is
missing beyond the measurement window selected.
•
Snapshot Live Stream: This button is used to populate the PID List Window with the PIDs
currently found in the stream. Use of this button is slightly different from most normal operations
within VLPro.
o Simply click the Snapshot Live Stream button and then the Refresh Configuration View
button; the Snapshot button is automatically applied.
o On an operational system ensure you de-select the PID List Template check box before
making a new snapshot, this will avoid alarm conditions being raised as the PID list
changes.
•
PID List Template: Once the PID List template has been populated and fully configured, this
check box must be checked to activate the PID List checking.
•
Reset PID Template: This button can be used to reset the PID List. All entries will be set to
"NOT SET", all Windows Measurements (WM) set to "Off" and the Switch Method will also be
set to "Off". This is useful when changing the switch from one stream to another stream and the
setting will be completely different. Make sure the PID List Template check box is not checked
before resetting to avoid unexpected switching.
