Abstract
Aspects of the present disclosure relate to managing licenses for playback of digital content. A license management device may create licenses that determine the number of playback devices that can be authorized by the license. Each license may be included in a corresponding digital content. In addition, each license may be distributed to a set of playback devices. Thereafter, a playback device may playback digital content that includes a license when the playback device stores a matching license. A single license can be used to provide authorization to play digital content from multiple sources and/or multiple types of content. Playback devices can store multiple licenses, which allows playback devices to belong to multiple sets of playback devices authorized to playback various digital content. In one embodiment digital content files can contain multiple licenses to allow the content files to be shared by multiple sets of playback devices.
