Abstract:
To provide a playback device capable of requesting for a content generated in a format compatible with its processing capability and playing back the content, with no need of user input of a user ID or the like. A playback device for playing back contents reads, from an external recording medium, a playback right of a content to play back one or more contents that each have been generated based on a content and in a format compatible with a processing capability different for each playback device, and transmits the playback right and capability information indicating a processing capability of the playback device to a server device. The playback device acquires, from the server device, one of the one or more contents corresponding to the playback right in a format compatible with its processing capability indicated by the capability information, and plays back the acquired content.
