摘要： A method is provided by which a client device obtains authorized access to content delivered over a content delivery network. The method includes receiving an entitlement management message (EMM). The EMM includes at least one cryptographic key and a device registration server certificate ID (DRSCID) identifying a currently valid device registration server (DRS) public key certificate. The DRSCID obtained from the EMM is compared to a stored DRSCID value. An entitlement control message (ECM), which includes an encrypted traffic key for decrypting content, is received. If the DRSCID obtained from the EMM is determined to match the stored DRSCID, the traffic key is decrypted with the cryptographic key or a key derived from the cryptographic key to thereby access the content.

摘要： A targeted discovery between a first device and a second device in a network, in particular, a WHDI network, provides discovery for an identified device or a group of identified devices. The targeted discovery determines an identifier for a second device or a group of devices that the second device belongs to, and sends a device discovery message to the second device using the identifier for the second device when the second device is configured to respond to the device discovery message if the device discovery message includes the identifier for the second device. The first device receives a response to the device discovery message from the second device and can start further communication with the second device.

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： 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.
