Title: Innovations of Charles R. Thompson

Introduction

Charles R. Thompson is a notable inventor based in Moorestown, NJ (US). He has made significant contributions to the field of video transmission technology, holding a total of four patents. His work has advanced the way digital television signals are processed and transmitted.

Latest Patents

One of Thompson's latest patents is for a differential PCM video transmission system employing horizontally offset. This system is designed for wide-aspect-ratio HDTV signals, which have 1600 luminance pixels and 980 lines per frame. The technology reduces data by deleting odd and even pixels from alternating TV fields, resulting in 800 pixels per line. Further compression is achieved through differential-pulse-code modulation (DPCM), which organizes pixels into groups and transmits reference pixels alongside difference signals. This innovative coding reduces the effective pixel count to 480 luminance samples and 240 color samples, ultimately producing 720 samples per line. Another significant patent involves a synchronization system that utilizes all valid signals. This system compares successive sync signals to create an error signal, allowing for the adjustment of digital signal delays during loss of synchronization.
