This article describes the work done in the industry on multichannel television sound standards for the reproduction of high-fidelity sound in TV receivers. The objectives for this improved television service are discussed, along with a short review of related laboratory tests and reports. The system devised by the EIA Broadcast Television Systems Committee (BTSC) is described in detail. In addition, some of the new FCC rules are explained which govern the use of subcarriers on TV for several purposes including stereophonic sound.
