Filed:

Dec 4, 2007

Appl. No.:

11/950093

Inventors:

Benoit F. Bazin - Milpitas CA, US
Cecile M. Foret - Mountain View CA, US

Assignee:

LSI Corporation - Milpitas CA

International Classification:

H04N 7/12
H04N 11/02
H04N 11/04
H04B 1/66

US Classification:

37524001

Abstract:

An apparatus configured to process a digital video signal comprising an input circuit, a processing circuit and an encoder circuit. The input circuit may be configured to present a digital video signal comprising a plurality of frames. The processing circuit may be configured to detect scene changes in the digital video signal by analyzing (i) a current one of the plurality of frames and (ii) two or more other frames. The encoder circuit may be configured to generate an encoded signal in response to the digital video signal and the scene changes. The two or more other frames may comprise (i) a first window of frames that are processed before the current frame and (ii) a second window of frames that are processed after the current frame. The processing circuit may also detect the scene changes by analyzing changes between the first window and the second window.
