Title: Isabelle Lemaguet and Video Signal Encoding
Introduction
Isabelle Lemaguet is an inventor associated with Paris, France, and Koninklijke Philips N.V. Her work includes a patent on preprocessing video signals to support reliable encoding.
Latest Patents
Lemaguet is named on one patent, Method and Device for Encoding Video Signal. The invention addresses video sequences made up of frames containing two fields. It describes receiving successive frames and delaying them by at least two field durations, then detecting changes in field dominance and adjusting the delay accordingly. Depending on the direction of the change, the method suppresses a field or repeats one to maintain suitable timing for encoding.
The patent also describes selecting preprocessing based on whether a sequence contains film-type or video-type images. For film-type sequences, the system applies inverse 3:2 pull-down; otherwise, it uses the described approach for handling changes in field dominance. Lemaguet’s listed patent count is 1 patent.
Career Highlights
Lemaguet’s patent work is associated with Koninklijke Philips N.V. The invention focuses on video-signal processing before encoding or other compression operations.
Collaborations
The provided information lists Pierre Gautier and Sandra Del Corso as Lemaguet’s coworkers.
Conclusion
Isabelle Lemaguet’s documented invention contributes a method for adapting video preprocessing to field-dominance changes and image-sequence type, supporting the preparation of video signals for encoding.
