Patent number: 6845485Abstract: An automated video editing and indexing system is taught which has application for such tasks as creating a presentation for a video magazine and processing collections of video material in general. The system extracts text either from closed captions (CC) contained in the analog video presentation, or extracted from the voice contained in the presentation by voice-to-text techniques, time-stamps the CC text in text files according to position in the video presentation, and digitizes the video presentation. The text files and digitized video are sent to an editing station, where the CC text is analyzed using Natural Language Processing and other techniques to determine topic changes in the presentation. Keyframes are selected to represent the topic changes, and become thumbnails useful in indexing; indexing meaning marking the video material at points of topic changes, and in some cases jumping the video presentation to the positions represented by the thumbnails.Type: GrantFiled: May 31, 2000Date of Patent: January 18, 2005Assignee: HOTV, Inc.Inventors: Vijnan Shastri, Indranil Chakraborty

Patent number: 6493872Abstract: A system for synchronizing data streams meant to be displayed concurrently at an end station, but delivered by separate delivery networks is disclosed. In one aspect, apparatus and methods for marking one of the data streams relative to the other are taught, including insertion of frame numbers in vertical and horizontal blanking intervals, the numbers referring to frames in the other stream and related to timing markers, and inserting such numbers by pixel data alteration. In another aspect, apparatus and methods are taught for receiving and re-synchronizing the data streams at a delivery point, including decoding of the relationship data inserted in one data stream referring to the other data stream. Re-synchronization is accomplished by controlling the separate data streams in separate buffer pipelines by a single controller. In a preferred embodiment one data stream is a live video data stream and the other is an annotation stream having added material to be displayed with the live video data stream.Type: GrantFiled: October 7, 1998Date of Patent: December 10, 2002Assignee: InnovatvInventors: P.

Patent number: 6357042Abstract: An authoring system for interactive video has two or more authoring stations for providing authored metadata to be related to a main video data stream and a multiplexer for relating authored metadata from the authoring sources to the main video data stream. The authoring stations annotate created metadata with presentation time stamps (PTS) from the main video stream, and the multiplexer relates the metadata to the main video stream by the PTS signatures. In analog streams PTS may be created and integrated. In some embodiments there may be multiple and cascaded systems, and some sources may be stored sources. Various methods are disclosed for monitoring and compensating time differences among sources to ensure time coordination in end product. In different embodiments transport of metadata to an end user station is provided by Internet streaming, VBI insertion or by Internet downloading.Type: GrantFiled: January 22, 1999Date of Patent: March 12, 2002Inventors: Anand Srinivasan, Mehul Y Shah, Indranil Chakraborty, Mohan Mardikar, P Venkat Rangan, Kamal Bhadada
