Filed:

Jul 20, 2006

Appl. No.:

11/489840

Inventors:

William L. Scherlis - Pittsburgh PA, US
Eric Burns - Seattle WA, US

Assignee:

Carnegie Mellon University - Pittsburgh PA

International Classification:

G11B 27/00
H04N 5/76

US Classification:

386278, 386291

Abstract:

A system for video compositing is comprised of a storage device for storing a composite timeline file. A timeline manager reads rendering instructions and compositing instructions from the stored file. A plurality of filter graphs, each receiving one of a plurality of video streams, renders frames therefrom in response to the rendering instructions. 3D hardware is responsive to the rendered frames and the compositing instructions for creating a composite image. A frame scheduler is responsive to the plurality of filter graphs for controlling the frequency at which the 3D hardware creates a new composite image. An output is provided for displaying the composite image. Methods of generating a composite work and methods of generating the timeline file are also disclosed. Because of the rules governing abstracts, this Abstract should not be used to construe the claims.

International Classification:

H04N 7/12
H04J 3/06

US Classification:

37524028, 370350

Abstract:

Various acquisition streams are delivered, synchronously or asynchronously, to a server. Those streams having local time indicia are synchronized with the global timeline and the various acquisition streams are then stored. Low bit rate streams corresponding to the stored acquisition streams are generated for use in subsequent editing of the acquisition streams. The editing of the acquisition streams entails reviewing the various acquisition streams and selecting portions for replay. The portions selected for replay are identified through metadata which is then stored. The replay or distribution mode begins by editing the global timeline using the metadata generated in the editing mode so as to produce an edited timeline. The various acquisition streams are then rendered or played back according to the edited timeline to produce a distribution stream.
