Automated presentation capture, storage and playback system

摘要

A video input device senses a visual portion of a presentation and produces video signal information corresponding to the visual portion. A user interface is provided for inputting presentation identification information relating to a presentation. The audio signal information, video signal information and presentation identification information are stored as a presentation set. The system further includes a presentation management portion in communication with the presentation capture portion. The presentation management portion includes a character recognition device for generating text character information from the presentation set video signal information and adding the text character information to the set. The presentation set is stored in a database that includes a database indexing system for generating an index of text character information from the presentation set, and a database search program for searching the index for selected information contained therein. The presentation playback portion includes an input query system for formulating and directing search requests to the database search program. An output display device displays search results following a search request. Based on the search results, users can selectively replay a presentation set from the database.
