"abstract": "Early in 1984, the Electronic Industries Association (EIA) and the National Association of Broadcasters (NAB) recommended that the FCC adopt the Broadcast Television Systems Committee (BTSC) system for multichannel TV sound (MTS) as a standard for US TV broadcasting. In March of 1984, the FCC ruled that the BTSC system (along with others) may be used by US television stations wishing to transmit MTS. Significantly, the BTSC system was granted protection from interference with its pilot tone, transmitted at the horizontal scanning rate, 15,734 Hz. This protection, along with the strong industry consensus, has encouraged the television industry to adopt BTSC generally for commercial-television production1 and increasingly for broadcasting.2",
