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： The systems disclosed here provide a complete standards-based end-to-end scalable system for storage, delivery and in-home distribution of digital content over IP networks using standard protocols such as Real-time Transport Protocol ("RTP") or IP-encapsulated MPEG-2 Transport Stream, or traditional MPEG-2 networks. Mechanisms are provided for receiving (65) content from one security domain, re-encrypting (73, 76) that content uniquely for a receiving device (50), persistently storing (77) that content (86), and playing back that content (86) at a later time to and within another security domain. The systems also provide the ability to stream the persistently-stored content from the initial receiving device to another device (300) that has been authenticated as part of a, e.g., home network. This allows a media server, e.g., a dual-tuner set-top box ("STB") with hard drive (170) , to deliver recorded content to any TV in the house by streaming to media clients such as STBs.
摘要翻译：这里公开的系统提供了一种完整的基于标准的端对端可扩展系统，用于使用诸如实时传输协议（“RTP”）或IP-IP的标准协议通过IP网络存储，传送和在家内分发数字内容，封装的MPEG-2传输流或传统的MPEG-2网络。提供用于从一个安全域接收（65）内容的机制，对接收设备（50）唯一地重新加密（73,76）该内容，持续存储（77）该内容（86）并且播放该内容（86） 86）在较晚时间到另一个安全域内。这些系统还提供将持续存储的内容从初始接收设备流式传输到已经被认证为例如家庭网络的一部分的另一设备（300）的能力。这允许诸如具有硬盘驱动器（170）的双调谐器机顶盒（“STB”）的媒体服务器通过流向诸如STB的媒体客户端将记录的内容传送到房屋中的任何电视。

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.
摘要翻译：

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.

摘要： The present invention discloses an apparatus and method for transferring digital content data. In one example, original digital content data stored on a first device in an encrypted state is transcoded (after being decrypted) to create a modified version of the original digital content data. The modified version of the original digital content data is then encrypted with a new content key. The modified version and at least one content key generator are transferred to a second device, where the at least one content key generator is used to recreate the new content key for enabling (and decrypting) the modified version of the original digital content data at the second device. Notably, the original digital content data stored in the first device is disabled contemporaneously with the transfer of the modified version and the at least one content key generator to the second device. Afterwards, the disabled original digital content data is re-enabled on the first device, and disabled on the second device.
