 Local storage duration when remote server is
unreachable
: enter the time during which the content should
be bufferized if during a push action, the remote server becomes
unreachable. When the remote server is available again, all the
content is sent at once.
 Define backup remote Web server : if set to true , the
stream is also sent to a backup remote Web server for
redundancy purposes. Indicate the URL and the IP address of
the backup server to the dedicated fields, as well as the
authentication parameters, if needed.
 Generate merge manifest : if set to true , the manifests will
reference all the streams sent to main and backup servers.
 Encrypt files : if set to true , DRM is activated. Set the following
parameters:
 Key server connection : select the conditional access server
to which Electra VS should connect to get the key from the
drop-down list. If set to
None , Electra VS generates the key itself.
Otherwise, enter the specific parameters of the CAS server:
- Content id (Nagra , Irdeto , PolyMedia, ZTE ): identifier of
the program to encrypt (string).
- Resource id ( Verimatrix ): identifier of the program to
encrypt (integer).
- Account Id ( Irdeto ): identifier of the account to connect to
the Irdeto server.
- Use last key ( Irdeto, Viaccess ): 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.
- Key server URL : URL of the CAS server. DNS is not
supported for this URL, so the IP address shall be explicitly
contained by the URL.
- 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.
Before using this feature, check that the bandwidth is widely
dimensioned, because otherwise there is a risk of network
congestion when the remote server is back up, which can impact
other streams.
