Abstract
In accordance with the domain management for digital media, a device obtains multiple pieces of protected content from multiple content providers, where two or more of the content providers employ different digital rights management systems. The device also accesses a license server to obtain, for each piece of protected content, a content license that is bound to a domain. The content license permits the device to play back a piece of protected content.
