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.

Dependent claims

A method of generating and using a multimedia bookmark for a position selected within a multimedia file of a multimedia content, comprising:

generating bookmark position information identifying a selected position within said multimedia file;
generating a title or image representing said selected position;
linking said title or image and said bookmark position information to stored profile information for said multimedia file and variations of said multimedia content, wherein said profile information includes an offset and a scale of each of a plurality of multimedia files containing said content with respect to a master file of said multimedia content;
invoking the multimedia bookmark;
and
calculating a playback position of a playback file based on said bookmark position information, where said calculating comprises:

A method of locating a playback position in a multimedia playback file based on a multimedia bookmark generated in connection with a bookmarked multimedia file, said method comprising:

selecting a multimedia file, referred to as a playback file;
invoking a multimedia bookmark from which a bookmarked position can be determined, additionally, by using said multimedia bookmark, enabling access to an offset and a scale for each of said playback file and said bookmarked multimedia file from which said multimedia bookmark was generated;
determining a time scale ratio from said scale for said playback file and said scale for said bookmarked file;
and
calculating a playback position based on said bookmarked position, said time scale ratio, said offset for said playback file, and said offset for said bookmarked file;
