摘要： 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. Executing the local playlist includes, for each packet, requesting a corresponding remote packet from the DRM proxy application to the server, returning the remote packet to the DRM proxy application, acquiring a license to access the remote packet, accessing the remote packet in the DRM proxy and returning the accessed packet to the native player as a local packet to be displayed.

摘要： 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.

摘要翻译： 该方法用于控制包括多媒体播放器的用户设备的代理服务器的数据速率，以及适于与多媒体播放器通信的代理服务器。 代理服务器还与多媒体服务器进行通信。 该方法包括从多媒体播放器接收对多媒体内容的请求，向多媒体服务器请求多媒体内容，从多媒体服务器接收多媒体内容的多个分组，估计用户设备与多媒体服务器之间的数据速率 ，并且基于估计的数据速率向多媒体播放器发送用于多媒体内容的数据流。
