Abstract

A method and system are provided for tagging, indexing, searching, retrieving, manipulating, and editing video images on a wide area network such as the Internet. A first set of methods is provided for enabling users to add bookmarks to multimedia files, such as movies, and audio files, such as music. The multimedia bookmark facilitates the searching of portions or segments of multimedia files, particularly when used in conjunction with a search engine. Additional methods are provided that reformat a video image for use on a variety of devices that have a wide range of resolutions by selecting some material (in the case of smaller resolutions) or more material (in the case of larger resolutions) from the same multimedia file. Still more methods are provided for interrogating images that contain textual information (in graphical form) so that the text may be copied to a tag or bookmark that can itself be indexed and searched to facilitate later retrieval via a search engine.

Claims

1. A method for creating a virtually edited multimedia file, comprising:

providing an input metadata file associated with a multimedia file, the metadata file having at least metadata of one segment that is selectable;

selecting a segment having its metadata in the metadata file;

determining if a composing segment should be created, and if the composing segment should be created, then creating a composing segment in a hierarchical structure;

specifying a composing segment in the hierarchical structure, and creating a component segment as a child node of the specified composing segment;

determining if metadata of the selected segment is to be copied or if a URI of the metadata is to be used, and if the metadata is to be copied, then copying metadata of the selected segment to the component segment, and if the URI is to be used, then writing a URI of the metadata of the selected segment to the component segment;

adding a URL of the multimedia file to the metadata of the component segment;

determining if the URLs added to the metadata of all siblings of the component segment are the same, and if the URLs are the same, then adding the URL to the specified composing segment and deleting the URL from all siblings of the component segment.

2. The method of claim 1 wherein the metadata file is an XML file.

3. The method of claim 1, the method further comprising:

determining if another segment having its metadata is to be selected, and if another segment having its metadata is to be selected, then returning to the step of selecting a segment having its metadata in a metadata file.

4. The method of claim 3, the method further comprising:

determining if another input metadata file is to be used, and if another input metadata file is to be used, then returning to the step of providing an input metadata file.
