Abstract
A method and apparatus for searching for multimedia files in a distributed database and for displaying results of the search based on the context and content of the multimedia files.
Claims40
A method comprising:
- examining a media object to locate portions of the media object having a plurality media object comprises digital video;
- determining a preview image size by computing an aspect ratio A and determining a target height IH of said preview image as the preview height FH less the height of any top and bottom border and determining a target width IW of said preview image as a function of said target height IH and said aspect ratio A;
- selecting images from said media object for display in said preview;
- storing said preview of the media object based on said content-based predetermined characteristics;
- searching a database of previews based on one or more of said content-based predetermined characteristics;
- and
- displaying the preview in response to the search.

A method for storing a representation of a media object comprising:
- examining said media object to locate portions of the media object having a plurality of content-based predetermined characteristics, wherein the media object comprises digital video;
- determining a preview image size by computing an aspect ratio A and determining a target height IH of said preview image as the preview height FH less the height of any top and bottom border and determining a target width IW of said preview image as a function of said target height IH and said aspect ratio A;
- selecting images from said media object for display in said preview;
- and
- storing said preview of the media object.

A method comprising:
- examining a media object to locate portions of the media object having a plurality of context-based and content-based predetermined characteristics based on a proximity of lexical information, wherein the context-based and content-based predetermined characteristics may include video characteristics and audio characteristics the audio characteristics comprising amplitude activity determined by a music-speech metric;
- storing a preview of the media object;
- searching a database of previews based on one or more of said context-based and content-based predetermined characteristics;
- and
- displaying the preview in response to the search.

A method comprising:
- examining a media object to locate portions of the media object having a plurality of predetermined characteristics, wherein the predetermined characteristics are content-based charcteristics including video characteristics and audio characteristics, the audio characteristics comprising audio amplitude activity determined by a music-speech metric;
- storing a preview of the media object and
- searching a database of previews based on one or more of said predetermined characteristics;
- and
- displaying the preview in response to the search.
2 more elements
A method comprising:
- examining a media object to locate portions of the media object having a plurality of predetermined characteristics, wherein the predetermined characteristics are content-based characteristics;
- determining a preview image size;
- selecting images from said media object for display in said preview by decompressing frames of said media object at N points and analyzing each of said frames to determine if said frames meet predetermined characteristics;
- if said frames do meet said predetermined characteristics, selecting said frames for display;
- if one of said frames do not meet said predetermined characteristics, selecting a substitute frame;
- storing a preview of the media object;
- searching a database of previews based on one or more of said predetermined characteristics;
- and
- displaying the preview in response to the search.

- a step for determining a preview image size by computing an aspect ratio A and determining a target height IH of said preview image as the preview height FH less the height of any top and bottom border and determining a target width IW of said preview image as a function of said target height IH and said aspect ratio A;
- a step for selecting images from said media object for display in said preview;
- a step for storing said preview of the media object;
- a step for searching a database of previews based on one or more of said content-based predetermined characteristics;
- and
- a step for displaying the preview in response to the search.
