6.3 OTT (requires the OTT Option)
6.3.1 Active testing
The OTT option enables monitoring of OTT channels. Up to five OTT engines, each
individually licensed, can work in parallel, and one engine can analyse up to ten OTT
channels sequentially. If the probe is licenced with more than one OTT engine the user
is free to allocate the total number of channels between engines. As an example a
probe licenced with two OTT engines may have five channels allocated to one engine
and fifteen to the other.
The probe will parse a channel's manifest file, and for a live stream one of the latest
chunks in each OTT profile's chunk sequence will be analysed. The engine then moves
on to the next OTT channel in the channel list defined by the user. For a VoD stream
the OTT engine will analyse all chunks in the VoD file, one in each round-robin loop.
If manifest file parsing or chunk analysis reveals an error, an alarm will be raised. Note
that some alarms depend on user defined threshold values. Alarms must also be
enabled in the
Alarm – Alarm setup
view.
