    摘要: A “managed copy” capability is provided that is both sanctioned and supervised by a service provider so that multimedia content distributed on optical media such as DVD can be copied and used by a client in a controlled manner. In an illustrative example, a content provider generates a fingerprint using heuristics and/or other data that uniquely identifies a multimedia release, like a feature film, as being authorized for copying according to defined usage rules. A managed copy service authorizes the client to make a copy of a source DVD if that source is found to match a stored fingerprint. An identification response, which may include encoding parameters and usage rules, provides confirmation to the client that content on the source DVD is authorized to be copied. The client copies content from the source to another medium in compliance with the identification response.

    摘要: In one or more embodiments, a license associated with a first piece of content can grant rights with respect to a second and/or additional pieces of content. That is, language that is included in a first license can express a policy that is interpreted by a client-side device. This policy can establish rights with respect to additional pieces of content. Accordingly, policy enforcement with respect to licensed content can take place on the client-side device and can establish how different content is to be played relative to one another.
