摘要： Various embodiments provide content protection interoperability techniques which support secure distribution of content for multiple content protection technologies. In one or more embodiments a source digital rights management (DRM) system can associate trust data with content to be exported to a target digital rights management (DRM) system. The trust data describes a trust state for the content to enable the target DRM system to maintain the trust state for the exported content. In at least some embodiments, the source DRM system can also associate tracing data with the content to, in the event of a breach in the chain of trust, enable an identification to be made of a source of the exported content and/or a party responsible for exporting the content.

摘要： Various embodiments utilize a third party, such as a trusted third-party, to perform DRM operations such as “move” operations. In at least some embodiments, the trusted third-party is utilized for both “move” operations as well as local content access such as playback and the like. In at least some embodiments, a third-party maintains a database that includes an association of clients, content, and move version numbers. A client—termed a “source client” maintains at least a move version number locally in a secure fashion. The version number is incremented each time the source client performs a move operation. Both the source client and the third-party increment the version number each time a piece of content is moved. When the client attempts to perform a move operation, it contacts the third-party to ascertain the third-party's move version number. If the move version numbers match and the source client owns the license/content, then, in at least some embodiments, a move operation is permitted.

摘要： This document describes tools capable of renewing an expired license to entertainment content. The tools, in some embodiments, may repeatedly renew a license using very little resources, such as by forgoing retention of the license, encryption keys, or the entertainment content between renewals. The tools, for example, may provide a license to a particular content receiver (e.g., a laptop computer), and, when that license expires, renew the license with as little as a single retained secret. By so doing the tools enable, among other things, fewer computing resources to be used in renewing a license while maintaining the security of that license's entertainment content.
摘要翻译：本文档描述了能够将已过期许可证更新为娱乐内容的工具。在一些实施例中，这些工具可以使用非常少的资源来重复地更新许可证，例如通过在续订之前保留许可证，加密密钥或娱乐内容。例如，这些工具可以向特定内容接收器（例如，膝上型计算机）提供许可证，并且当该许可证到期时，以仅一个保留的秘密来更新许可证。通过这样做，除了别的以外，这些工具还能够在维护许可证娱乐内容的安全性的同时更新许可证中使用的更少的计算资源。

摘要： A system and method for synchronizing disparate processing modes and for providing mutually exclusive access to shared system resources. A processing unit operates in disparate first and second processing modes. In the first processing mode, the computer is under the control of an operating system. In the other processing mode, the computer is under the control of a system management mode interrupt handling routine. To synchronize the two processing modes and allow mutually exclusive access to shared hardware resources, the computer system includes shared memory, which contains an intermodal lock, and a mechanism for allowing each processing mode to signal the other. Before either processing mode can access the shared resource, the processing mode must attempt to acquire the intermodal lock. If the lock is acquired, the processing mode accesses the shared resource. If the lock cannot be acquired, the processing mode sets a pending bit and resumes other tasks until it receives a lock release signal from the other processing mode. When a processing mode has finished accessing the shared resource, it releases the lock and checks to see if the pending bit was set. If so, the processing mode sends a lock release signal to the other mode.
摘要翻译：用于同步不同处理模式并提供对共享系统资源的互斥访问的系统和方法。处理单元以不同的第一和第二处理模式进行操作。在第一处理模式中，计算机处于操作系统的控制之下。在其他处理模式下，计算机处于系统管理模式中断处理程序的控制之下。为了使两种处理模式同步并且允许对共享硬件资源的互斥访问，计算机系统包括共享存储器，其包含联锁，以及允许每个处理模式发信号通知给另一个的机制。在任一处理模式可以访问共享资源之前，处理模式必须尝试获取多式联锁。如果获取锁，则处理模式访问共享资源。如果无法获取锁定，则处理模式设置待处理位并恢复其他任务，直到从其他处理模式接收到锁定释放信号。当处理模式已经完成对共享资源的访问时，它释放锁并检查是否设置了未决位。如果是这样，则处理模式将锁定释放信号发送到另一个模式。

摘要： A hierarchical data structure is created in dynamic memory that is dynamically expanded or modified during run-time operations of the computer system. Information about the devices is loaded from a definition block into the hierarchical data structure. The information is a byte stream of data that is translated and stored as hierarchical information, such as device objects, data objects, and control method objects. These objects are hierarchically nested within the hierarchical data structure. A device object identifies a corresponding device in the computer system. The hierarchy formed between device objects represents the hierarchical I/O connections within the computer system. A data object identifies configuration and hardware dependency information associated with a corresponding device. A control method object is an executable reference for controlling a corresponding device. The control method object is a sequence of pseudocode instructions interpreted by the operating system providing an abstract, extensible, and portable mechanism for precise control of a device without calling routines from the BIOS.The hierarchical data structure is preferably used by the operating system as a communication tool and reference to identify devices, to identify configuration and power management information about devices, to provide an executable control mechanism that is abstract and extensible to control devices, and to extensibly add functionality to a device.

摘要： Waking a computer from a system state. A wake data structure enables a device to wake the computer from a sleeping state. The lowest system state is identified that allows selected devices to still wake the system based on the contents of the wake data structure for the device. A chosen device power state is selected for each of the devices within the computer system and each device is placed within their respective chosen device power state. Wake devices have a particular chosen device power state that supports that wake device's capability of waking the computer system. Other devices are typically turned off. Finally, the operating system turns off any of power resources within the computer system that are no longer used by any of the devices.
