Figure 6.9 Slate Detection Settings
If the slate has been triggered, an alarm referring to this condition (frozen video) is
raised, unless the slate has also been triggered by one of the other two Action On
features, in which case only the alarm referring to both frozen video and silent audio
is raised.
6.6.2.1.3 Option Detect under Action On > Silent Audio
This feature monitors a single audio component belonging to the service. It can only
detect silence in streams that are transcoded, since pass-through streams are not
decoded. The selection is made by stream number which bears no relationship with
PIDs or other service metadata. It is recommended to check that the expected
component has been selected by hovering over it in the Outputs pane with the
mouse.
