Abstract: A compatible multivoice broadcasting receiver is disclosed which can receive both Korean multivoice broadcasting and American multivoice broadcasting and commonly process the one-carrier component (L+R) of Korean multivoice broadcasting and the main channel signal (L+R) of American multivoice broadcasting. In addition to the existing multivoice broadcasting receiver, the multivoice broadcasting receiver further comprises a buffer section that operates the outputs L+R signal detector, L-R and SAP signal detector, and the L-R and pilot signal detector selectively under the control of a buffer driving section, the buffer driving section operating a buffer section, an analog switch section for switching the signal transmission according to the output signal from the buffer driving section, and a matrix section for matrix-operating the output signals from the buffer section according to the output signal from the analog switch section and for outputting the left channel signal and the right channel signal.
