Browser for use in navigating a body of information, with particular application to browsing information represented by audiovisual data

Abstract

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., online 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.

Description

[0001] 1. Field of the Invention[0002] This invention relates to systems and methods that enable observation of a body of information and, in particular, a body of information that can be represented, at least in part, by audiovisual data. Most particularly, the invention relates to systems and methods for accessing and reviewing a body of information represented by one or more sets of audiovisual data that can be used to generate an audiovisual display and one or more related sets of text data that can be used to generate a text display.[0003] 2. Related Art[0004] The increasing complexity of the modern world, and the concomitant explosion in the amount of information available to describe that world, has placed competing demands on people. There is more subject matter that people find necessary or desirable to master or, at least, be familiar with. At the same time, there is less time to spend delving into any particular subject. Too, there is a much larger universe of information...

Benefits of technology

Enables users to quickly access and review information, identify related content, and control the display format, facilitating efficient navigation and overview of complex information sets through real-time data organization and simultaneous display of related segments.

Problems solved by technology

The increasing complexity of the modern world, and the concomitant explosion in the amount of information available to describe that world, has placed competing demands on people.

Trying to get just an overview of a large body of information can be overwhelming, and attempting to find specific material within the body of information can be like searching for a needle in a haystack.

For example, while some previous systems for enabling observation of a large body of information enable identification of one or more segments of information that are related to a specified segment of information, these systems do not automatically display such related segments of information.

Further, previous systems have not enabled determination of relatedness between segments of information represented by different types of data, e.g., such systems cannot determine whether a segment represented by audiovisual data is related to a segment represented by text data.

Previous systems and methods for accessing and reviewing a body of information are deficient in one or more of these respects.

Typically, the display device of these systems (e.g., conventional computer display monitor) does not provide a high quality display of time-varying audiovisual information (such as produced by a television, for example).

On the other hand, display devices that do display such information well (e.g., televisions), typically do not provide a high quality display of text information (such as produced by a computer display monitor).

Additionally, previous systems for reviewing a body of information are not as flexible or convenient to use as is desirable.

Therefore, the system can not be operated remotely, thus constraining the user's freedom of movement while operating the system.

Additionally, even in those systems where remote operation is possible (e.g., remotely controlled televisions), the remote control device often does not have a user interface that is as readily accessible as desired (as many consumer electronics users can testify, the keypads of many remote control devices are an impenetrable _array of cryptic control keys, often requiring non-intuitive key combinations to effect particular control instructions) or the remote control device does not contain a rich set of control features.

Moreover, the remote control devices used with previous systems do not have the capability of themselves displaying a part of the body of information.

Further, previous systems often do not enable real-time acquisition and review of some or all of the body of information.

However, insofar as previous systems for observing a body of information allow real-time acquisition and review of the body of information, these systems generally do not analyze the data to enable the data to be organized, categorized and related so that, for example, segments of the body of information can be related to other segments for which data is acquired in the future or for which data has previously been acquired.

Moreover, such systems do not enable the real-time display of some or all of a body of information while also displaying related information in response to the real-time display.
