摘要： Management of rights to content is provided within an authorized domain. In a single authorized domain, where a plurality of domain interfaces are protected using a common rights management system, a copy of particular content may be allowed to be provided on all devices or only on specific devices coupled to the domain via the interfaces. Copy protection information, for outputs to external devices not protected by the common rights management system, is also specified. Rules can be provided for specifying whether particular content may be copied or moved to another protected domain. A number of rendering devices permitted to render the content simultaneously may be specified. Content rules are provided for use in managing rights to content within an authorized domain. Such rules can be associated with content that is persistently stored by a consumer device, as well as with content that is only rendered by a consumer device.

摘要： A process may be utilized by a DVR. The process characterizes a set of content as a plurality of segments as the set of content is received. Each of the segments has a segment length according to a predetermined time interval. Further, the process encrypts each of the segments with a corresponding content encryption key to generate a plurality of encrypted segments. The corresponding content encryption key for each of the segments is generated by the DRM component. In addition, the process stores each of the encrypted segments for playback with trick play features in accordance with an expiration content rule having a time limit on the temporary playability of the set of content.

摘要： A process composes a content license for a set of content. The content license has a static portion and a dynamic portion. Further, the process inserts a master key into the static portion. In addition, the process inserts a plurality of content rule sets of values into the dynamic portion and composes a unique content encryption key for each segment of content associated with one of the content rule sets of values as each of the content rule sets of values is sequentially received during recording of the content. The unique content encryption key is based on the master key and at least a subset of the content rule set of values for a corresponding segment of the content. The unique content encryption key is utilized for encryption of each segment of the content to generate a plurality of encrypted content segments for storage on the storage medium.

摘要： Method and apparatus for transferring protected content between digital rights management systems is described. One aspect of the invention relates to importing content from an upstream digital rights management (DRM) system into a device in a downstream DRM system. Data is received that associates at least one device in the downstream DRM system with a rights issuer module (RIM). Authenticity of the data is verified as originating from an entity in a trust hierarchy of the device. If the data is authentic and the device is one of the at least one device associated with the RIM, a ciphertext version of the content and a corresponding content license is accepted from the RIM.
