Offline playback

Enabling offline playback consists of two stages:

Offline playback of clear content

The lifecycle for offline playback of clear content is as follows:

To acquire a downloadable asset, the application must register the content URL to the downloader. The downloader provides information about the asset to download during that step.
The application triggers the effective download and persistency of the media data.
The application can watch the downloaded asset in a similar manner to streamed content.
The application purges the asset when the user no longer needs it.

The player must have been created, and the application configured to play clear content.
A clear stream with download enabled is available for testing.

Additional steps are required where the content is encrypted:

The application registers the content URL to the downloader. The downloader provides information about the asset to download during that step.
If the content is PRM-protected, the application must retrieve the associated licence, either by using its own identifier mechanism or using the PRM content ID exposed on the download. A challenge/response exchange occurs with the licence server, and the licence payload that the server returns must be imported into the PAK by the application.
If the licence import is successful, the application can then trigger the effective download and persistency of the media data.
Once the licence and the asset are successfully acquired, the application can watch the downloaded asset in a similar manner to streamed content.
The application purges the licence and asset when the user no longer needs it.

The player must have been created and the application configured to play clear content.
An encrypted stream with download enabled is available for testing
