Title: Edwin R Tarmain: Innovator in Television Communication Systems

Introduction

Edwin R Tarmain is a notable inventor based in London, Canada. He has made significant contributions to the field of television communication systems, particularly through his innovative patent that enhances the distribution of television signals.

Latest Patents

Tarmain holds a patent for a digital, frequency-translated, plural-channel, vestigial sideband television communication system. This system is designed to distribute multiple VSB digitally encoded TV channels via an optical transmission link to various distribution terminals. At the headend, the frequency band of each VSB signal is shifted down to baseband and transmitted in digital format. Each station along the network converts the digitized baseband VSB television signal back into analog format and then reshifted through an up-converter to its original IF band, ensuring compatibility with the television receiver circuitry of subscribers. The invention employs optical communication techniques to couple the digitally encoded frequency-shifted VSB television signals between stations. To maintain signal strength and quality, repeater units are strategically placed in the optical communication link, converting incoming optical signals to electrical signals for amplification before reconverting them back into optical form for further transmission.
