Title: Pierre Charbonnel: Innovator in Audio and Video Signal Processing

Introduction

Pierre Charbonnel is a notable inventor based in Betton, France. He has made significant contributions to the fields of audio and video signal processing, holding two patents that showcase his innovative approach to technology.

Latest Patents

Charbonnel's latest patents include a method and system for multiplexing audio and video signals to distribute. This invention involves converting an audio signal into a sequence of digital code words, from which subwords are extracted relative to a video signal line frequency. The number of bits in each subword is determined based on the amplitude dynamic range of the video signal. Each extracted digital subword is then converted to provide analog samples, which are used to amplitude modulate an active portion of the video signal, resulting in a composite signal that maintains the format of the video signal. Another significant patent is the process and apparatus for digital data communication using packet. This invention addresses the consequences of packet loss in digital data communication by structuring digital data as multibit words into frames and assembling these frames into packets of a predetermined length. The system allows for the determination of lost packets at the receiver location by monitoring index words, and it can generate substitution data for missing samples.
