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： Method and apparatus providing program information to client devices for at least one multicast stream of digital content is described. In one embodiment, session description messages for the at least one multicast stream of digital content are generated. Each of the session description messages includes at least one content access parameter. The at least one content access parameter may include digital rights management (DRM) data, channel key identification data associated with the at least one channel of the at least one multicast stream of digital content, and/or data indicative of whether each session description message is associated with a channel, a program, or a program segment. Each of the session description messages is signed using a cryptographic key. The session description messages are then multicasted to the client devices using a predefined multicast address.

摘要： The present invention discloses an apparatus and method for a method for determining proximity of a device (e.g., a client device). In one example, a key management request is acquired from the device. A measurement request is then transmitted to the device. Afterwards, a measurement reply is received from the device. In response, a determination is made as to whether a measurement parameter associated with the transmitting and the receiving exceeds a predetermined threshold. If the predetermined threshold is not exceeded (i.e., the device is proximate to an associated local network), then a reply to the original key management request is transmitted to the device. Notably, the reply to the key management request is required for the device to establish a secure session with a server from which digital content can be acquired.

摘要： A digital rights management system (DRM) for restricting and permitting content access in a digital content distribution network such as a network used to deliver television programming. The DRM uses distributed authentication and provisioning so that the potentially many different entities involved in the content distribution network can have localized management and control. Distributed authentication can use single or multiple instances of authentication services. A ticket granting service (TGS) is used to allow clients to request services. In one approach, multiple authentication services use a common key that is known to the TGS. In another approach, unique keys are provided to each authentication service and these keys are communicated to the TGS. Distributed provisioning allows different entities to grant access rights or other resources. Provisioning service (PS) processes can execute at multiple different physical locations. Synchronization among the different PSs is provided by a managing entity or in a peer-to-peer transfer to help ensure the uniqueness of user IDs. New clients can make an initialization request from a key management system via an appropriate protocol. The requests can be made from a single, dedicated authentication service, from an authentication service associated with a specific provisioning service, or from multiple authentication services in the network.
摘要翻译：一种数字版权管理系统（DRM），用于限制和许可数字内容分发网络中的内容访问，例如用于传送电视节目的网络。 DRM使用分布式认证和配置，使得涉及内容分发网络的潜在许多不同实体可以具有本地化的管理和控制。分布式身份验证可以使用单个或多个身份验证服务实例。票务授予服务（TGS）用于允许客户端请求服务。在一种方法中，多个认证服务使用TGS已知的公共密钥。在另一种方法中，向每个认证服务提供唯一的密钥，并将这些密钥通信给TGS。分布式配置允许不同的实体授予访问权限或其他资源。配置服务（PS）进程可以在多个不同的物理位置执行。不同PS之间的同步由管理实体或对等传输提供，以帮助确保用户ID的唯一性。新客户端可以通过适当的协议从密钥管理系统发出初始化请求。可以从单个专用认证服务，从与特定供应服务相关联的认证服务或从网络中的多个认证服务进行请求。
