COMMUNICATION SYSTEM AMD CONTROL METHOD OF THE SAME

摘要

PURPOSE: A broadcast communication system and control method thereof are provided to improve broadcasting stereo sound quality by minimizing signal loss generated by voice signal transmission through optical signal transmission. CONSTITUTION: An original sound input unit(100) changes an original sound provided from outside into a voice signal. A mixing unit(200) mixes a voice signal and outputs to plural ports which is already connected a mixed voice signal. An optical signal transmission unit(300) successively modulates, filters and amplifies plural voice signals. An optical cable(400) interlinks the optical signal transmission unit and an optical signal reception unit. The optical fiber cable transmits the plural optical signals inputted from the optical transmission unit to the optical signal reception unit.
