Title: Francoise Roussel: Innovator in Numerical Transmission Systems
Introduction
Francoise Roussel is a notable inventor based in La Chapelle des Fougeretz, France. She has made significant contributions to the field of numerical transmission systems, particularly through her innovative patent. Her work has implications for both digital television and high-fidelity sound transmission.
Latest Patents
Francoise Roussel holds a patent for a "System of numerical transmission with adaptative coding." This invention utilizes an adaptive coding system for numerical or digital transmission. The system samples and transforms log information through orthogonal transformation. The coding reduces the data flow rate by employing an adaptive threshold. In each scanning field, binary elements of the coefficients are derived from basic coding with a quantification pitch of 2S, where S is a whole number. A complementary coding is also transmitted, which is achieved by adding binary elements of weights 2S-1 for each coefficient until the channel's transmission capacity is reached. The coefficients are processed in chronological order, making this invention applicable to various digital transmission applications.
