Use an Elemental with a DVR Display Engine
Updated
Live Event Setup
Access the Elemental’s web interface to begin the process. To create a new event, click on “New Event +” in the upper right corner.

- Enter a name for the Event
- Select the Input Type. Typically, this will be an SDI input. Be sure to verify with the client which SDI input will be used.

You can click the Preview button to the right of the Input field to see if there is an active video signal on that input. If there is not a signal, the interface will tell you.


Output Groups
-
Delete all output groups except for Apple HLS. You can do this by pressing the X next to the output group.
-
Rename the Custom Group Name to something like sardius_dvr
-
In the Destination Field, adjust the following template and then enter it into this field:
- http://ep2.storage.sardius.media/ep2/hls/_accountID_/_name_/playlist
- accountID = Client’s Account ID
- name = event name
- http://ep2.storage.sardius.media/ep2/hls/_accountID_/_name_/playlist
-
Adjust your segment length to 10 seconds.
-
Change the HTTP Push Dialect to Basic PUT

Outputs
DVR requires a single HLS output. Once you have created your output, proceed to “Streams”
Output 1: 1080
- In the “New Output” section, click on “Add Output+” on the right-hand side.
This will create a new output and a new stream called Stream 1 - In the Name Modifier, enter -1080
Streams
Now it’s time to configure the stream that is being fed to each output.
Each Stream will need some unique configuration based upon the designated resolution. We will also notate what items will need to be changed/added from the default settings.
We'll go through the full steps for the 1080 Stream, and then we'll provide a table for the remaining streams.
