User-directed navigation of multimedia search results

Abstract

A method and apparatus for timed tagging of content is featured. The method and apparatus can include the steps of, or structure for, obtaining at least one keyword tag associated with discrete media content; generating a timed segment index of discrete media content, the timed segment index identifying content segments of the discrete media content and corresponding timing boundaries of the content segments; searching the timed segment index for a match to the at least one keyword tag, the match corresponding to at least one of the content segments identified in the segment index; and generating a timed tag index that includes the at least one keyword tag and the timing boundaries corresponding to the least one content segment of the discrete media content containing the match.

Description

RELATED APPLICATIONS[0001]This application is a continuation-in-part of U.S. patent application Ser. No. 11 / 395,732, filed on Mar. 31, 2006, which claims the benefit of U.S. Provisional Application No. 60 / 736,124, filed on Nov. 9, 2005. The entire teachings of the above applications are incorporated herein by reference.FIELD OF THE INVENTION[0002]Aspects of the invention relate to methods and apparatus for generating and using enhanced metadata in search-driven applications.BACKGROUND OF THE INVENTION[0003]As the World Wide Web has emerged as a major research tool across all fields of study, the concept of metadata has become a crucial topic. Metadata, which can be broadly defined as “data about data,” refers to the searchable definitions used to locate information. This issue is particularly relevant to searches on the Web, where metatags may determine the ease with which a particular Web site is located by searchers. Metadata that are embedded with content is called embedded metad...

AI Technical Summary

Benefits of technology

Enables users to efficiently locate and play back specific segments of audio / video content by generating detailed metadata, improving search accuracy and user-directed navigation within media files.

Problems solved by technology

With respect to media files or streams, the metadata information that describes the audio content or the video content is typically limited to information provided by the content publisher.

If this limited information fails to satisfy a search query, the search engine is not likely to provide the corresponding audio / video podcast as a search result even if the actual content of the audio / video podcast satisfies the query.
