Proxy license acquisition model: In this workflow, the subscriber’s device and player application communicates with a proxy service managed by the OTT service provider, which redirects the requests back to the multi-DRM service.
The client application initializes the media player with the DRM license acquisition URL, which triggers a ott drm license acquisition call to the ExpressPlay multi-DRM service endpoint.
Therefore, the client application will need to retrieve the DRM license before the DRM token expires. This approach prevents an attacker from retrieving the DRM license from the multi-DRM service because the DRM token is not valid after the set time period.
