A multi-channel PCM high-quality audio transmission system (for use on terrestrial and satellite radio-relay video facilities) has been developed for diplexing up to four 15-kHz audio channels onto a single video channel. This system, called DATE (Digital Audio for Television), was developed to provide a combined audio-with-video transmission system. The system has two sections: the ADA (analog-digital-analog) which converts the program audio into binary information and then back into audio; and the modem which provides the 5.5-MHz digital sub-carrier used to convey the binary audio information.
