The BTSC Multi-Channel Television Sound System

Carl G. Eilers

The BTSC multi-channel television sound (MTS) system provides for a full 15-kHz audio response stereo pair with low distortion and signal-to-noise ratio (SNR) equivalent to the monophonic audio component. A second audio program channel with a 10-kHz audio response at reasonably low distortion and an SNR slightly inferior to the monophonic main program, and a professional channel for use by the broadcaster are also provided. More than 150 TV stations have gone on the air with BTSC MTS since FCC authorization on April 23, 1984, and two major networks are providing programs in stereo sound. This article describes the system and compares it with FM stereophonic broadcasting.
