User Manual
- 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.
- 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.
™ Key : enter the value of the key (32 characters).
MPEG-DASH Output
The MPEG-DASH output receives audio/video components, creates the
chunks and manifests and makes them available on the local Web server.
Figure 3-112. MPEG-DASH output parameters
For this item, you must set the following parameters:
„ Available stream duration : depth of chunks that are available on the
Web server.
Upon an important configuration change, it is necessary to restart
the IIS server. For instance, when adding a new video profile, the
VS7000 stops the IIS server and restarts it. However, for this restart
action to be possible, the IIS server configuration must authorize it.
To to so, the IIS server administrator must add the following line in
the isml file:
<meta name="restartOnEncoderReconnect"
content="true" />
Without this line being present, the administator will need to restart
manually the IIS server publishing point.
