Title: Innovations of Jean-Pierre M Henot

Introduction

Jean-Pierre M Henot is a notable inventor based in Thorigne Fouillard, France. He has made significant contributions to the field of digital image processing, holding a total of four patents. His work focuses on encoding and transmission methods that enhance the quality and efficiency of digital images.

Latest Patents

One of his latest patents is an encoding and transmission method that utilizes at least two levels of quality for digital pictures. This method involves cutting each digital picture into blocks of picture elements, applying a reversible mathematical transformation to these blocks, and quantizing the coefficients of the transformed picture blocks. The quantized coefficients are then encoded and divided into at least two digital trains. The first train contains basic coefficients for standard quality picture reconstruction, while the second train includes complementary coefficients for higher quality images. This innovative approach allows for the transmission of digital images that can be effectively received by both moving and fixed receivers, even under challenging conditions.

Another significant patent by Henot is a throughput regulation method for assistance data in the reconstruction of subsampled moving electronic images. This method is particularly beneficial for HDTV transmission via a HMAC channel. It involves selecting an optimal processing operation for each elementary block of the image from two parallel processing operations. The first operation generates a higher data throughput rate, while the second operation, which includes an image filter, produces a lower rate. If the throughput rate approaches the maximum allowed for a transmission unit, the system automatically selects the second processing operation to maintain efficiency.
