An enabled DVR option allows for the stream caching up to 4 hours: the viewers would be able to see your stream later, pause it or play it back.
It is a paid feature. You can discuss the activation price with the account manager or send the request to the technical support via a live chat or at email@example.com.
Once the activation is confirmed, you will be able to activate the feature for your streams.
To check the DVR feature, go to the demonstration page.
