摘要： In some embodiments, the invention is a personal digital network (“PDN”) including hardware (sometimes referred to as Ingress circuitry) configured to transcrypt encrypted content that enters the PDN. Typically, the transcryption (decryption followed by re-encryption) is performed in hardware within the Ingress circuitry and the re-encryption occurs before the decrypted content is accessible by hardware or software external to the Ingress circuitry. Typically, transcrypted content that leaves the Ingress circuitry remains in re-encrypted form within the PDN whenever it is transferred between integrated circuits or is otherwise easily accessible by software, until it is decrypted within hardware (sometimes referred to as Egress circuitry) for display or playback or output from the PDN. Typically, the PDN is implemented so that no secret in Ingress or Egress circuitry (for use or transfer by the Ingress or Egress circuitry) is accessible in unencrypted form to software or firmware within the PDN or to any entity external to the PDN. Other aspects of the invention are methods for protecting content in a PDN (e.g., an open computing system) and devices (e.g., multimedia graphics cards, set top boxes, or video processors) for use in a PDN.
摘要翻译：在一些实施例中，本发明是一种个人数字网络（“PDN”），其包括配置成对进入PDN的加密内容进行加密的硬件（有时称为入口电路）。通常，在入口电路内的硬件中执行转录（后续是重新加密的解密），并且在加密内容可以通过入口电路外部的硬件或软件访问之前发生重新加密。通常，离开入口电路的加密内容在PDN之间保持重新加密的形式，无论其在集成电路之间传输还是由软件容易地访问，直到在硬件（有时称为出口电路）中被解密以进行显示或从PDN播放或输出。通常，PDN被实现为使得入口或出口电路（用于入口或出口电路的使用或传输）中的秘密可以以未加密的形式被访问到PDN内的软件或固件或PDN外部的任何实体。本发明的其他方面是用于保护PDN（例如，开放式计算系统）中的内容和用于PDN中的设备（例如，多媒体图形卡，机顶盒或视频处理器）的方法。

摘要： In a class of embodiments, the invention is an open computing system (e.g., a PC) in which a protected, closed subsystem is embedded. The closed subsystem typically includes multiple parts that ensure that content protection keys and protected content are never revealed outside the closed subsystem. Content (e.g., high-definition digital video) that enters the closed subsystem (and is typically decrypted and re-encrypted within the closed subsystem) is afforded a similar level of protection within the open system as can be obtained in standalone closed systems. Other aspects of the invention are methods for protecting content within an open computing system, a closed system (or disk drive thereof) configured to be embedded in an open computing system, and circuitry configured to be embedded in an open computing system for combining the output of a closed subsystem with other output (e.g., graphics and/or audio output) of the open computing system.
摘要翻译：在一类实施例中，本发明是其中嵌入了受保护的封闭子系统的开放式计算系统（例如，PC）。封闭的子系统通常包括多个部分，确保内容保护密钥和受保护内容永远不会在封闭子系统外部显示。进入封闭子系统（并且通常在封闭子系统内被解密并重新加密）的内容（例如，高清数字视频）在独立的封闭系统中可获得与开放系统相似的保护水平。本发明的其他方面是用于保护开放式计算系统内的内容的方法，被配置为嵌入在开放式计算系统中的封闭系统（或其盘驱动器）以及被配置为嵌入开放式计算系统中的组合的输出的方法，具有开放式计算系统的其他输出（例如，图形和/或音频输出）的封闭子系统。

摘要： A method and apparatus for providing distributed clip-list management. In an embodiment, an application maintains a local clip-list that identifies those portions of a remote frame buffer that are unambiguously associated with the given application, as well as those portions of the remote frame buffer which are disputed between the given application and one or more other applications. Applications may enforce a dispute policy with respect to writing image data to disputed regions of the frame buffer. Applications are able to write to the frame buffer asynchronously, without the use of a frame buffer lock. A clip manager maintains a global clip-list, and responds to messages from the applications by updating the global clip-list and informing those other applications of relevant changes to their own respective local clip-lists. The portions of an application's clip-list that have been previously claimed by other applications and which have not been acknowledged as lost by the other applications are referred to as disputed regions. Each application is kept informed about its current clip-list and any disputed regions within its current clip-list. The clip manager may be implemented as part of the window manager, or as a separate process. A policing process may be implemented at or in line with the frame buffer to ensure that an application does not write to portions of the frame buffer that have been granted to another application. The operations of the policing process are coordinated by the clip manager.

摘要： The invention provides a central office metaphor to computing, where features and functions are provided by a one or more servers and communicated to an appliance terminal through a network. Data providers are defined as “services” and are provided by one or more processing resources. The services communicate to display terminals through a network, such as Ethernet. The terminals are configured to display data, and to send keyboard, cursor, audio, and video data through the network to the processing server. Functionality is partitioned so that databases, server and graphical user interface functions are provided by the services, and human interface functionality is provided by the terminal. Communication with the terminals from various services is accomplished by converting disparate output to a common protocol. Appropriate drivers are provided for each service to allow protocol conversion. Multiple terminals are coupled to the network. Users can enable their unique session at any one of the terminals by inserting a “smart card” into a card reader. Removing the card disables the session. Re-inserting the card into the same or any other terminal re-enables the session.
