Methods and systems for previewing content with a dynamic tag cloud

摘要

A video tapestry comprising a plurality of blended frames of a media presentation can be presented, with the frames comprising two or more frames displayed simultaneously. A dynamic tag cloud can be presented based on data identifying different portions of the tapestry for use in navigation or understanding the video content. A method can comprise obtaining a plurality of keywords for content of a media presentation, associating a first keyword with a first tag cloud and associating a second keyword with a second tag cloud, and generating a program component for providing a dynamic tag cloud using the first and second tag clouds. The program component can display the first tag cloud when the first portion of the video tapestry is referenced and the second tag cloud when the second portion of the video tapestry is referenced. The portions may be referenced by user input, a play head, or other activity.

主权项

1. A method, comprising:
displaying a video tapestry comprising a plurality of blended frames of a media presentation comprising video content, the video content comprising a plurality of frames, the plurality of blended frames of the media presentation being simultaneously displayed in the video tapestry, wherein the plurality of blended frames is a first subset of the plurality of frames of the video content of the media presentation which does not include another subset of the plurality of frames of the video content of the media presentation; wherein the plurality of blended frames comprises a plurality of frame pairs, each frame pair comprising a respective first frame from the first subset of the plurality of frames of the video content and a respective second frame from the first subset of the plurality of frames of the video content, wherein the respective second frame is not adjacent to the respective first frame in the plurality of frames; wherein, for each frame pair, a respective first content portion of the respective first frame and a respective second content portion of the respective second frame are blended together such that the plurality of blended frames forms a visually continuous image summarizing the media presentation; determining, based on accessing data that groups subsets of the plurality of blended frames into a plurality of portions of the video tapestry, that an overlap portion of the video tapestry has been identified by an input received via an interface in which the video tapestry is displayed, wherein the overlap portion comprises at least two portions from the plurality of portions of the video tapestry each having at least one common frame; and responsive to determining that an overlap portion of the video tapestry has been identified by the input received via the interface:
identifying a first tag cloud associated with a first portion in the overlap portion and a second tag cloud associated with a second portion in the overlap portion, anddisplaying simultaneously the first and second tag clouds based at least in part on the first and second portions being in the overlap portion, wherein the first tag cloud is generated from a first text portion of a transcript of the video content that corresponds to the first portion in the overlap portion and the second tag cloud is generated from a second text portion of the transcript of the video content that corresponds to the second portion in the overlap portion.
