Abstract

Devices, methods, and program products are provided, which support multiple Digital Rights Management (DRM) schemes or platforms during the placeshifting of media content. A given placeshifting session may be initiated between a placeshifting device and a user-controlled client media receiver executing a browser player. In one embodiment, the DRM placeshifting method includes storing, in a memory associated with the placeshifting device, DRM-protected content; receiving a request from the client media receiver over a communications network to stream the DRM-protected content to the device; and obtaining a placeshifting key and initialization instructions for the DRM-protected content. The DRM-protected content is streamed to the client media receiver in an encrypted format accessible with a placeshifting decryption key. In conjunction with streaming the DRM-protected content, initialization instructions is transmitted to the client media receiver containing information utilized by the browser player to obtain the DRM license from a first license server.
