Title: Charles R. Burr: Satellite Communications and Television Signal Innovations

Introduction

Charles R. Burr is an inventor associated with Palm Bay, Florida. His patent work addresses satellite communications and television signal processing, including frequency synchronization, signal calibration, and scrambling. He holds 2 patents.

Latest Patents

Burr’s patent, “Mechanism for Deriving Accurate Frequency Reference for Satellite,” describes a way to synchronize satellite communication equipment without requiring high-precision oscillators at remote stations or a dedicated pilot tone. A precision clock establishes the outbound and return-channel carriers, and remote stations recover that clock from the outbound signal to generate their return carriers. At the master station, the continuous outbound carrier provides a frequency reference for demodulating burst transmissions, helping compensate for frequency changes introduced during satellite transmission.

His patent, “Digitally-Controlled Analog Encryption,” describes a television-scrambling system that selectively inverts picture lines according to a pseudorandom sequence. It also uses calibration signals representing black and white levels to help receivers correct signal gain and offset. A randomly inserted key code resets the pseudorandom generator, while the audio signal is scrambled by shifting its carrier between two offset frequencies.
