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： The present invention discloses an apparatus and method for reserving a set of requested rights. In one example, the digital rights data associated with digital content information is found in a remaining rights file using a license index. A portion of the digital rights data is subsequently reserved. A determination is made as to whether a content download associated with the digital content information is successful. If the content download is unsuccessful, then the reserved portion of the digital rights data is cancelled. Alternatively, if the content download is successful, then the remaining rights file is updated to reflect a use of the portion of the digital rights data.

摘要： A method and apparatus are for transferring a client device certificate and an associated encrypted client private key to a client device from a secure device. The secure device receives over a secure connection, a secure device certificate, a secure device private key and a plurality of client device certificates. Each client certificate is associated with a bootstrap public key but is not assigned to any particular client device. A plurality of encrypted client private keys is also received. Each of the encrypted client private keys comprises a client private key associated with one of the client device certificates encrypted with the bootstrap public key. The plurality of client device certificates is stored. The encrypted client private keys are stored in double encrypted protected form. A client device certificate and an associated encrypted client private key are transferred to a client device that has successfully registered with the secure device.

摘要： A process may be utilized by the DVR. The process receives a plurality of segments of a set of content and a plurality of corresponding content rule sets. Further, the process provides one or more instructions to record and encrypt the plurality of segments of the set of content on a storage medium. In addition, the process provides the plurality of content rule sets to the DRM component to be inserted into a locally generated and secured content license associated with the encryption of the set of content. The secured content license includes a master key and a list of the plurality of corresponding content rule sets that have been received in order of reception. The process receives a plurality of marker tokens from the DRM component in order to facilitate trick mode playback.

摘要： A session rights object and authorization data are used for defining a consumer's access right to a media content stream. The access rights are determined at a caching server remotely located from the consumer rather than locally at the end user site. In a first aspect, in a computing network having a content provider, a key distribution center, a caching server and a client, a method for controlling client access to a real-time data stream from the caching server, is disclosed. The method includes receiving, by the client, a session rights object from a content provider, the session rights object defining access rules for accessing the real-time data stream; receiving, by the client, authorization data from the key distribution center, the authorization data defining the client's access rights to the real-time data stream; forwarding to the caching server the session rights object and the authorization data; comparing, by the caching server, the session rights object with the authorization data to determine client authorization; and if the client is authorized, streaming, by the caching server, the real-time data stream to the client.
摘要翻译： 会话权限对象和授权数据用于定义消费者对媒体内容流的访问权限。 访问权限在远程位于消费者的缓存服务器上确定，而不是在最终用户站点本地。 在第一方面，在具有内容提供商，密钥分配中心，高速缓存服务器和客户端的计算网络中，公开了一种用于控制来自高速缓存服务器的客户端对实时数据流的访问的方法。 该方法包括从客户端接收来自内容提供商的会话权限对象，会话权限对象定义用于访问实时数据流的访问规则; 由客户端从密钥分配中心接收授权数据，定义客户端对实时数据流的访问权限; 转发到缓存服务器会话权限对象和授权数据; 通过缓存服务器比较会话权限对象与授权数据，以确定客户端授权; 并且如果客户端被授权，则通过缓存服务器流式传输到客户端的实时数据流。
