    • A system and related techniques detect and manage the set of rights associated with a componentized electronic document, including to separately protect and manage individual text, graphic, audio, video or other parts of a multimedia presentation. Unlike prior digital asset management platforms which could enforce encryption or other protection simply around the entire object, the invention permits individualized control over separate media components, to permit distribution for example of some parts, such as text passages, while preventing unauthorized access or copying of audio, photographic, video or other files or content. The electronic document may maintain a list of media components and the set of rights associated with each such component, and a content server or other source may apply key encryption or other safeguards to guide the delivery of the overall media object or its parts, for instance to view in a browser, print on a printer or otherwise access, manipulate or output the content.
    • 系统和相关技术检测和管理与组件化电子文档相关联的一组权限,包括分别保护和管理多媒体呈现的单个文本,图形,音频,视频或其他部分。 不同于以前的数字资产管理平台,可以简单地在整个对象上实施加密或其他保护,本发明允许对单独的媒体组件进行个性化控制,以允许例如某些部分(例如文本段落)的分发,同时防止未经授权的访问或复制 音频,摄影,视频或其他文件或内容。 电子文档可以维护媒体组件的列表和与每个这样的组件相关联的一组权限,并且内容服务器或其他源可以应用密钥加密或其他保护措施来引导整个媒体对象或其部分的传递,例如 在浏览器中查看,在打印机上打印或以其他方式访问,操纵或输出内容。

    • Disclosed is a central cache that is updated without the overhead of locking. Updates are “atomic” in that they cannot be interrupted part way through. Applications are always free to read data in the cache, accessing the data through a reference table. Applications do not directly update the cache, instead, they send update requests to a service routine. To update the cache, the service routine proceeds in two phases. In the first phase, the service routine prepares the new data and adds them to the cache, without updating the reference table. During the first phase, an application accessing the cache cannot “see” the new data because the reference table has not yet been updated. After the first phase is complete, the service routine performs the second phase of the update process: atomically updating the reference table. The two-phase update process leaves the cache, at all times, in a consistent state.
    • 公开了一种在没有锁定开销的情况下更新的中央缓存。 更新是“原子的”,因为它们不能被中断。 应用程序始终可以自由地读取缓存中的数据,通过参考表访问数据。 应用程序不直接更新缓存,而是将更新请求发送到服务程序。 为了更新缓存,服务程序分两步进行。 在第一阶段,服务程序准备新数据并将其添加到缓存中,而不更新参考表。 在第一阶段,访问高速缓存的应用程序不能“查看”新数据,因为参考表尚未更新。 第一阶段完成后,服务程序执行更新过程的第二阶段:以原子方式更新参考表。 两阶段更新过程始终保持高速缓存,始终处于一致状态。
