Abstract
A method for playing DRM-protected contents, the protected contents being downloaded by a user device from a media server in the form of protected segments, comprises executing a DRM proxy inside the user device, the DRM proxy interfacing the media server and a player configured to implement the HLS protocol; executing an HLS server in the DRM proxy; registering the DRM proxy to handle HTTP requests; producing by the DRM proxy a playlist in HLS format including a list of URLs locating the individual protected segments on the user device; processing the playlist in the player; in the DRM proxy, acquiring a license to access the protected segment identified by the URL of a current request; decrypting the protected segment in the DRM proxy based on the license; and returning a segment based on the decrypted segment to the player in response to the current URL request.
