摘要： In a method for communicating media content stored on a digital video recorder (DVR) protected by a first DRM system to a portable multimedia device (PMD) using a second DRM system, in which the first DRM system differs from the second DRM system, a request for communication of a media content item stored on the DVR to the PMD is received. In addition, a portable content key is employed to encrypt the media content item to a PMD format suitable content version and the encrypted PMD format suitable content version is communicated to the PMD along with a portable content identifier (ID).
摘要翻译：在使用第二DRM系统将存储在由第一DRM系统保护的数字视频记录器（DVR）上的媒体内容传送到使用第二DRM系统的便携式多媒体设备（PMD）的方法中，其中第一DRM系统与第二DRM系统不同，接收到将存储在DVR上的媒体内容项目与PMD通信的请求。此外，使用便携式内容密钥将媒体内容项目加密到适合于内容版本的PMD格式，并且将加密的PMD格式适当的内容版本与便携式内容标识符（ID）一起传送到PMD。

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.
摘要翻译：一个进程组成一组内容的内容许可证。内容许可证具有静态部分和动态部分。此外，该过程将主密钥插入静态部分。此外，该过程将多个内容规则集值集合插入到动态部分中，并且对于与内容规则集值之一相关联的每个内容段，构成唯一内容加密密钥，因为每个内容规则集值是在记录内容期间顺序地接收。唯一内容加密密钥基于主密钥以及内容的相应段的内容规则集合的集合的至少一个子集。独特的内容加密密钥用于加密内容的每个段，以生成用于存储在存储介质上的多个加密的内容段。

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： Systems and methods for secure content distribution, including a content server, a rights management server, a residential gateway communicating with the content server and the rights management server via a network, and a playback device communicating with the residential gateway via a local network. The residential gateway receives protected content from the content server. The playback device requests access to the protected content from the residential gateway. The residential gateway requests access to the protected content from the rights management server by including information uniquely identifying the playback device. The rights management server provides access information to the residential gateway when the access information satisfies predetermined criterion for playback devices associated with the residential gateway. The residential gateway decrypts the protected content using the access information and encrypts the decrypted content for distribution to the playback device via a secure link formed between the residential gateway and the playback device.

摘要： A digital rights management architecture for securely delivering content to authorized consumers. The architecture includes a content provider and a consumer system for requesting content from the content provider. The content provider generates a session rights object having purchase options selected by the consumer. A KDC thereafter provides authorization data to the consumer system. Also, a caching server is provided for comparing the purchase options with the authorization data. The caching server forwards the requested content to the consumer system if the purchase options match the authorization data. Note that the caching server employs real time streaming for securely forwarding the encrypted content, and the requested content is encrypted for forwarding to the consumer system. Further, the caching server and the consumer system exchange encrypted control messages (and authenticated) for supporting transfer of the requested content. In this manner, all interfaces between components are protected by encryption and/authenticated.

摘要： A method and system for transmitting content from a content provider to a caching server and then from the caching server to a viewer. The method comprises encrypting the content with a pre-encryptor application before the content is transmitted to the caching server. The pre-encryptor application uses a pre-encryption subkey provided by a key storage service to perform the pre-encryption. The key storage service is a stand-alone component of the system and generates, stores, and distributes the pre-encryption subkeys.
