Method and apparatus for transmitting/receiving broadcasting-communication data

摘要

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.

1. A broadcasting-communication data receiving apparatus for receiving mixed signals including original signals and additional signals, comprising:
a receiver configured to receive the mixed signals and convert the mixed signals into mixed signals of a predetermined band, the mixed signals of the predetermined band including
original signals of the predetermined band corresponding to the original signals of the mixed signals, andadditional signals of the predetermined band corresponding to the additional signals of the mixed signals; a first demodulator configured to receive the mixed signals of the predetermined band and generate baseband mixed signals therefrom; an original data generator configured to receive the baseband mixed signals and generate original data therefrom; an original signal generator configured to receive the original data and generate baseband original signals therefrom; a modulator configured to receive the baseband original signals and generate the original signals of the predetermined band therefrom; a subtractor configured to subtract the original signals of the predetermined band from the mixed signals of the predetermined band to thereby generate the additional signals of the predetermined band; a second demodulator configured to receive the additional signals of the predetermined band and generate baseband additional signals therefrom; and an additional data generator configured to receive the baseband additional signals and generate additional data therefrom.
