Abstract
Some embodiments of the invention provide a content-distribution system. In some embodiments, the content-distribution system distributes device-restricted content and device-unrestricted content. Device-restricted content is content that can only be played on devices that the system associates with the particular user. Device-unrestricted content is content that can be played on any device without any restrictions. However, for at least one operation or service other than playback, device-unrestricted content has to be authenticated before this operation or service can be performed on the content. In some embodiments, the system facilitates this authentication by specifying a verification parameter for a piece of device-unrestricted content. The content-distribution system of some embodiments has a set of servers that supply (1) media storage structures that store content, (2) cryptographic keys that are needed to decrypt device-restricted content, and (3) verification parameters that are needed to verify device-unrestricted content.
