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 nullbackgroundnull 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 nullforegroundnull 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： Two-way digital media devices typically store digital identifying data that identify the user to providers of content and interactive data. In the case of a Web browser of a personal computer, the digital identity is stored in the form of a plurality of cookies that are used by respective web sites to personalize the web site experience for each particular user. When a user is at a different computer, the digital identifying data is not available. In addition, other types of interactive devices, such as CATV settop boxes, cell phones, PDAs and the like, may not have enough non-volatile memory (persistent storage) to store the digital identifying data. In order to provide users with a portable digital identity, a digital identity server is provided as a server node on the Internet, which retrieves digital identifying data and downloads such digital identifying data to any device upon request. In such manner, the user's digital identity is portable and available at any computer or other digital device that is being used. The system digital identity server permits devices without sufficient non-volatile memory storage to download a digital identity for temporary storage in volatile memory, thereby providing a digital identity in devices without non-volatile memory.

摘要： Internet access is provided over a digital cable television system using Internet protocol (IP) over MPEG digital video. Simultaneous Internet access and TV viewing is provided by an IP over MPEG-2 video system with channel tracking. Whenever a video channel change is detected, the viewer's Internet connection is routed from one video channel to another video channel so that the Internet connection is dynamically routed and tracks the channel changes made by the viewer. Additionally, if there is no available data carrying capacity in the video channel selected by the viewer (a nullbusynull condition), the Internet connection is routed to an out-of-band frequency. The Internet connection tracks the channel changes made by the viewer using a single tuner/digital MPEG decoder in the CATV settop box.

摘要： An inventive client/server system provides a platform for cable system operators to deliver a full range of sophisticated new products to cable television subscribers. Preferably a middleware solution, the information platform provides a flexible, versatile, and adaptable Internet-centric platform that network operators can use to deploy interactive television applications. The information platform mediates the communication between an abundance of Web-based content and the television set. Content and applications are written entirely in industry standard HTML and Java. Traditional television programming is integrated with Web content using TV-specific extensions to HTML and Java. Applications can be loaded from the network, from carousels, or from file systems, such as flash memory or EEPROM. The information platform consists of client-side middleware integrated with a native electronic program guide application. It includes a master application that defines service functionality, TV ticker, a suite of games, and a microbrowser for broadcast managed content. The presently preferred embodiment of the information platform supports broadcast-only applications, i.e. applications not requiring a return path) and also provides limited support for two-way applications such as store and forward and imprint server for gathering subscriber interactions and statistics.

摘要： A system for enhancing the display of World Wide Web pages combined with television video signals on a TV screen includes enhanced display modes. In a first embodiment, the viewer controls the transparency of a Picture-In-Picture image (PIP). A PIP image that normally covers up a part of the background image is made transparent so that the user can view the background image through the PIP image. Using transparency control, two same size images are simultaneously viewed whereby a full size background image and a full size foreground image simultaneously occupy the full television video screen. In a second embodiment of enhanced display of television video and World Wide Web graphics, a television video Picture-In-Graphics (PIG) image is imbedded as an object in an HTML Web page. When the HTML Web page is displayed as a background image and scrolled (or panned), the television video PIG image scrolls along with the HTML Web page background image. In such manner, the smaller PIG image does not cover up an important part of the larger background graphics image.

摘要： User and network computer client device (NC) registration with an internet service provider (ISP) occurs in two phases: the first phase with the relationship server and the second phase with the ISP. In the first phase, the NC sends the relationship server a unique identifier of the NC manufacturer, such as the manufacturer identification number. In the preferred embodiment, the NC also transmits an enterprise identification number from a smart card uniquely specifying the ISP to which the user wishes to connect. The relationship server queries a relationship database using the manufacturer and enterprise identification numbers. In the preferred embodiment, the relationship server determines whether the specified manufacturer has authorized connection to the specified ISP; if no authorization exists in the relationship server database, then the relationship server disconnects from the NC. Otherwise, the relationship server transmits NC connection information and initial registration contents for the ISP to the NC. The NC preferably writes the initial registration contents to the user's smart card. In the preferred embodiment, the initial registration contents is identical for all users of the same ISP and is digitally signed by the ISP. The second phase of the user registration is entirely governed by the ISP. Upon authentication of the ISP using the authorized usage certificate for the ISP within the NC, the ISP is free to overwrite the user's initial registration contents user specific ISP account information that the ISP digitally signs. In the preferred embodiment, although the initial registration contents for the ISP on the user's smart card is overwritten during the second phase of user registration, the NC connection information remains the same after registration with the ISP. Although the ISP is allowed to overwrite this data (either the smart card contents or the NVRAM contents) at anytime.
