From January 13 to January 14, 1984, our school was commissioned by the Higher Education Bureau to hold the appraisal of scientific research achievements of “FM-FM TV double-sound broadcasting.” Guangdong Radio and Television Office, Guangdong Provincial Department of Higher Education and Beijing, Shanghai 28 units and 52 representatives from TV stations, institutions of higher learning, relevant research institutes and factories in Jiangsu, Hubei, Fujian and Guangdong provinces attended the conference. The participants listened to the “ FM FM television dual-sound broadcast research work and technical summary ”report,“ deputy modulator and demodulator technology ”report.“ FM-FM TV dual-sound pilot experiment ”report," deputy modulator and deputy solution After the full discussion, delegates and accreditation committees agreed that FM-FM TV dual-use Both sound accompaniment and closed-circuit broadcast sound clear, good sound quality, will not crosstalk with each other, the newly added vice sound on the image without interference, good compatibility, the main accompaniment sound and vice sound of the technical parameters All qualified.The delegates think FM-FM TV double-sound broadcast by South China Normal University first successful research, leading in the country
