摘要： There is a performing of digital rights management (DRM), operable in an offline mode with respect to a communications network. The performing includes identifying a stored rights object associated with a stored asset. The stored rights object includes reporting duration information associated with the stored asset. The performing also includes determining, utilizing a processor, whether a transmission of an early status message is a successful communication based on an early status message determination. If a failure in communicating the early status message is determined, utilizing the stored asset. The performing may also include transmitting an early status message and/or later status message after identifying the stored rights object. There is also a performing of digital rights management (DRM) associated with a DRM system and operable in an offline mode with respect to a communications network. There are also client devices, communicating systems, computer readable mediums and protocols.

摘要翻译： 数字版权管理（DRM）的执行可以在通信网络的离线模式下操作。 执行包括识别与存储的资产相关联的存储的权利对象。 存储的权利对象包括与存储的资产相关联的报告持续时间信息。 执行还包括基于早期状态消息确定来确定利用处理器是否早期状态消息的传输是成功的通信。 如果确定通信早期状态消息失败，则利用存储的资产。 执行还可以包括在识别所存储的权利对象之后发送早期状态消息和/或后续状态消息。 还存在与DRM系统相关联的数字权限管理（DRM）的执行，并且可以相对于通信网络以离线模式操作。 还有客户端设备，通信系统，计算机可读介质和协议。
