Abstract

A broadcasting-communication data receiving apparatus for receiving mixed signals including original signals and additional signals. The apparatus includes a receiver for receiving the mixed signals and outputting mixed signals of a predetermined band, a first demodulator for receiving the mixed signals of the predetermined band and generating baseband mixed signals, an original data generator for receiving the baseband mixed signals and generating original data, an original signal generator for receiving the original data and generating baseband original signals, a modulator for receiving the baseband original signals and generating original signals of a predetermined band, a subtractor for subtracting the original and mixed signals of the predetermined band to thereby generate additional signals of a predetermined band, a second demodulator for receiving the additional signals of the predetermined band and generating baseband additional signals, and an additional data generator for receiving the baseband additional signals and generating additional data.
