摘要： A secure processor assuring application software is executed securely, and assuring only authorized software is executed, monitored modes and secure modes of operation. The former executes application software transparently to that software. The latter verifies execution of the application software is authorized, performs any extraordinary services required by the application software, and verifies the processor has obtained rights to execute the content. The secure processor (1) appears hardware-identical to an ordinary processor, with the effect that application software written for ordinary processors can be executed on the secure processor without substantial change, (2) needs only a minimal degree of additional hardware over and above those portions appearing hardware-identical to an ordinary processor. The secure processor operates without substantial reduction in speed or other resources available to the application software. Functions operating in secure mode might reside in an on-chip non-volatile memory, or might be loaded from external storage with authentication.

摘要： A technique for DRM translation involves converting first digital content into second digital content. An example of a system according to the technique includes a server that provides a first digital content unit coded with a first digital format and use-right protected by first digital rights management (DRM). The system further includes a translator capable of converting the first digital content unit into a second digital content unit coded with a second digital format and use-right protected by second DRM.

摘要： Dynamic assignment of rights to content, such as in a closed distribution system. Noting state information generated by an item of current content, and modifying state or rights of new content in response. Pre-loading or dynamically sending new content to the owner of the current content, with rights being enabled only at a later time, in the playback device, with predetermined conditions. In response to current state information, dynamically sending a license for new content from a server. Conditional or dynamic licenses to new content, including a set of rights associated with a class of possible sets of state information. Assignment of limited rights to a content, with support in a secure player to enforce them; for purposes of rental, bonus content, trials and other business models.

摘要： The invention provides a method and system for receiving incoming information from multiple information sources, both interactive and passive, and for engagingly presenting that information to a recipient on a presentation interface. The system includes a "background" element, which interacts with interactive information sources and receives from passive information sources, and determines whether information from those sources is likely to be interesting to the recipient, possibly using one information source to determine priority for another. The system also includes a "foreground" element, which presents information to the recipient when active, but not when inactive. The background is operative even when the foreground element is inactive, and when the background detects new information of interest to the recipient (for example, exceeding a selected threshold of interest or satisfying a selected criterion for interest), it causes the foreground to become active and engage the recipient to select and view that new information. The threshold or criterion may be adaptively responsive to recipient preferences, whether explicitly expressed or implied, but may also be relatively fixed, such as a scheduled time of day.

摘要翻译： 本发明提供了一种用于从多个信息源（交互式和被动）接收传入信息并用于在呈现界面上将接收性地呈现给接收者的方法和系统。 该系统包括一个“背景”元素，其与交互式信息源交互并从被动信息源接收，并且确定来自这些源的信息是否可能对接收者感兴趣，可能使用一个信息源来确定另一信息源的优先级。 该系统还包括一个“前台”元素，当活动时向收件人显示信息，而不是处于非活动状态。 即使前景元素处于非活动状态，并且当背景检测到接收者感兴趣的新信息（例如，超过感兴趣的选定阈值或满足所选择的感兴趣标准）时，背景也是可操作的，这使得前景变得活跃 并让收件人选择并查看新信息。 阈值或标准可以自适应地响应于收件人偏好，无论是明确表示还是暗示，但也可以是相对固定的，例如一天的预定时间。

摘要： The invention provides a method and system for creating and customizing a home page that is used in conjunction with a technique for dynamically trading knowledge and services. A provider of knowledge, goods or services could request a home page on a web site dedicated to dynamically providing goods and services. Upon receiving the request, the provider of knowledge, goods or services is given the opportunity to create a specially customized home page. This homepage provides prospective buyers, with some or all of the following information: the name of the provider, the type of product, the amount of product available, a way of categorizing the product, a description, a fixed price, optional goods or services and other related information that would be helpful to those trying to identify providers of good and services and select among them. A provider of goods and services is guided through a step-by-step procedure, during which the provider is presented with a number of mandatory information fields that are used in creating a customized home page.
