    • A location-limited channel is implemented using physical exchanges of physical tokens. The physical tokens are implemented using writeable or re-writeable storage media. Location-limited channels, when used to implement pre-authentication protocols, provide demonstrative identification and authenticity. A group originator loads pre-authentication information and a network location from a communication device onto the location-limited physical token channel. The location-limited physical token channel is passed to another participant, who copies the originator's pre-authentication information and location onto that participant's communication device. That participant then adds that participant's own pre-authentication information and network location onto the location-limited physical token channel. This is repeated until the last participant passes the location-limited physical token channel back to the group originator. The originator thus has pre-authentication information and network locations for all other participants. The originator establishes secure communications with each participant based on the originator' and that participant's shared information.
    • 使用物理令牌的物理交换来实现位置限制信道。 物理令牌使用可写或可重写的存储介质实现。 位置限制通道用于实现预认证协议时,提供说明性识别和真实性。 组发起者将来自通信设备的预认证信息和网络位置加载到位置限制的物理令牌信道上。 位置限制物理令牌信道被传递给另一个参与者,他们将发起者的预认证信息和位置复制到该参与者的通信设备上。 然后,该参与者将该参与者自己的预认证信息和网络位置添加到位置有限的物理令牌信道上。 这是重复的,直到最后一个参与者将位置限制的物理令牌通道返回到组发起者。 因此,发起者具有所有其他参与者的预认证信息和网络位置。 发起人根据发起人和参与者的共享信息建立与每个参与者的安全通信。

    • The invention facilitates and enhances review of a body of information (that can be represented by a set of audio data, video data, text data or some combination of the three), enabling the body of information to be quickly reviewed to obtain an overview of the content of the body of information and allowing flexibility in the manner in which the body of information is reviewed. In a particular application of the invention, the content of audiovisual news programs is acquired from a first set of one or more information sources (e.g., television news programs) and text news stories are acquired from a second set of one or more information sources (e.g., on-line news services or news wire services). In such a particular application, the invention can enable the user to access the news stories of audiovisual news programs in a random manner so that the user can move quickly among news stories or news programs. The invention can also enable the user to quickly locate news stories pertaining to a particular subject. Additionally, when the user is observing a particular news story in a news program, the invention can identify and display related news stories. The invention can also enable the user to control the display of the news programs by, for example, speeding up the display, causing a summary of one or more news stories to be displayed, or pausing the display of the news stories. Additionally, the invention can indicate to the user which news story is currently being viewed, as well as which news stories have previously been viewed.
    • 本发明有助于和增强对一组信息(可以由一组音频数据,视频数据,文本数据或三者的一些组合来表示)的审查,使得能够快速地审查信息的主体以获得 信息内容的内容,并允许审查信息的方式的灵活性。 在本发明的特定应用中,从第一组一个或多个信息源(例如,电视新闻节目)中获取视听新闻节目的内容,并且从第二组一个或多个信息源获取文本新闻故事( 例如在线新闻服务或新闻线服务)。 在这样的具体应用中,本发明能够使用户以随机的方式访问视听新闻节目的新闻故事,使得用户可以在新闻故事或新闻节目中快速移动。 本发明还可以使用户能够快速定位与特定主题有关的新闻故事。 此外,当用户在新闻节目中观察特定的新闻故事时,本发明可以识别和显示相关的新闻故事。 本发明还能够使用户通过例如加速显示来控制新闻节目的显示,导致显示一个或多个新闻的摘要,或者暂停显示新闻故事。 此外,本发明可以向用户指示当前正在观看哪个新闻故事,以及先前已经看过哪些新闻故事。
