DE1285 Caption Decoder/VANC Monitor

3.2.4

ANC Trigger

The ANC Trigger tab allows you to create triggers made up of two parts:
the ANC data of interest, and the behavior you would like to observe.
The data type is selected using the DID/SDID value, and the trigger can
be set on behaviors such as Present, Absent, Change and DataChange.
Setting triggers is a useful way to monitor incoming ANC data to check
the frequency of events such as missing data. Using the web interface,
triggers can be chosen and then monitored in a live–update pop-up win-
dow that is tied to your browser session, making the ANC analysis tool
ideal for watching until an event occurs. To record triggers that will be
stored on the DE1285 for detailed viewing or to view information about
