The MC44C401 Multi-Channel Television Sound (MTS) Stereo Encoder is the
industry’s first, single-chip, CMOS implementation of a Broadcast Television Sys-
tems Committee (BTSC)-compatible stereo encoder.
The MC44C401 MTS Stereo Encoder is designed for use in set-top boxes, VCRs,
DVD players/recorders, game stations, and other applications that are required to
output high-quality stereo sound through a single RF coaxial cable.
The digital audio processing used in the MC44C401 preserves the full fidelity of sur-
round sound and other audio coding schemes while ensuring overall system perfor-
mance is not impacted by copy protection technologies.
The MC44C401 is engineered to process right and left analog audio signals and base-
band composite video to generate a stereophonic composite signal in accordance
with BTSC system standards. The MC44C401 is designed to output this signal to a
Motorola RF modulator, which in turn produces a stereo encoded RF channel for use
with any BTSC stereo television receiver.
