Abstract: The method and system are for playing digital contents protected by a DRM scheme, wherein the digital contents are stored in a server and downloaded or streamed to a user device. The approach includes executing a DRM application inside the user device implementing a proxy between the server and a native player of the user device, and connecting the DRM proxy application to the server, selecting a digital content to be downloaded and retrieving a corresponding remote playlist. Also, the approach includes transforming the remote playlist into a local playlist having a format readable from the native player and executing a plurality of local packets of the local playlist inside the native player.

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.

Abstract: The approach is for controlling a data rate of proxy server of a user device that includes a multimedia player, and a proxy server adapted to communicate with the multimedia player. The proxy server also communicates with a multimedia server. The approach includes receiving a request for a multimedia content from the multimedia player, requesting the multimedia content to the multimedia server, receiving a plurality of packets for the multimedia content from the multimedia server, estimating a data rate between the user device and the multimedia server, and sending a data stream for the multimedia content to the multimedia player based on the estimated data rate.
