摘要： Content delivered to client device over an Internet Protocol Multimedia Subsystem (IMS)-based network is protected through a digital rights management (DRM) scheme that leverages IMS service and access infrastructure, such as the IMS core. After authentication and selection of content to be played for the user, the network identifies a key management system having keys for decrypting the selected content. A bootstrapping service function participates in an application-level authentication of the client device to establish a secure communication channel between the key management system and the client device. The key management system responds to a content key request received from the client device by providing a content key via the secure communication channel. The network can then stream content to the client device, which decrypts it using the content key.

摘要： A process is provided. The process determines member devices in a domain of devices. Further, the process encrypts a set of content with a content encryption key to generate an encrypted set of content. In addition, the process encrypts the content encryption key with each of a plurality of pre-fetch keys to generate a plurality of encrypted content encryption keys. Each of the pre-fetch keys corresponds to a member device in the domain of devices. Finally, the process stores each of the encrypted content encryption keys in a content license corresponding to a member device in the domain of devices. The encrypted content may be stored on a removable medium. Further, the process allows another device to play back the content from the same removable medium.

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： 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： 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。
