Abstract: Provided are an apparatus for addition data transmission includes: an IF broadcasting signal generating unit receiving the broadcast data, and FEC and modulation of the received broadcast data to generate a broadcasting signal in an intermediate frequency (IF) band; an IF addition signal generating unit receiving the addition data to generate an addition signal in the IF band by using direct sequence spread spectrum (DSSS); an average power controlling unit controlling average power of the addition signal in the IF band; a signal combining unit combining the broadcasting signal in the IF band and the addition signal in the IF band to generate a combination signal; an RF upward converting unit upwardly converting the combination signal in a signal in a radio frequency (RF) band to a combination signal in the RF band; and a transmitting unit transmitting the combination signal in the RF band.

Abstract: The embodiments provide an additional information insertion apparatus for a broadcasting system. The system includes a broadcasting signal transmitter configured to transmit a broadcasting signal along with a data extractor configured to extract a modulated signal by dividing the modulated signal from a modulator of the broadcasting signal transmitter. An additional data generator is configured to extract synchronization of the broadcasting signal from the extracted broadcasting signal, modulate the additional information based on the extracted synchronization, and generate a level of the modulated additional information to be a smaller level than a signal level of the modulated signal by as much as a predetermined value. A data synthesizer is provided to insert the additional data from the data generator into the modulated broadcasting signal.

Abstract: An apparatus for embedding additional information that may embed additional information into a digital television (TV) broadcast signal and transmit the additional information is provided. The apparatus may modulate the additional information to an intermediate frequency/radio frequency (IF/RF), embed the modulated additional information into the digital TV broadcast signal, and compensate for a distortion that may occur in an RF part, thereby correctly transmitting the additional information.

Abstract: Disclosed is a co-channel feedback signal cancelling regenerative repeater of the Advanced Television Systems Committee (ATSC) that extracts a predetermined reference value of feedback signal to be able to cancel the feedback signal among received signals, including: a signal receiving unit; a signal demodulating unit that converts frequency of a received signal and demodulates it into a baseband signal; an interference equalizing unit that corrects characteristics of the demodulated signal and cancels feedback signal; a channel equalizing unit that compensates for channel distortion of an original signal from which the feedback signal is cancelled; a modulating unit that modulates the channel distortion-compensated original signal and converts it into an analog signal; and a signal transmitting unit that converts the frequency of the modulated signal, controls and amplifies its gain, and transmits a regenerative transmission signal.
