- Use last key ( Irdeto ): Set to true to return the last registered
encryption key for a specified live event. Use this method if
an encoding session reuses the last generated encryption
key for the live event instead of generating a new key. This
is particularly useful when multiple encoders are
configured, to use the same encryption key for a live event.
Set to
false to generate and return a new PlayReady
encryption key for the specified live event.

supported for this URL, so the IP address shall be explicitly

- Define backup key server : set to true if you want to declare
a backup CAS server. Enter the URL of this backup server in
the
Backup key server URL field.
