    摘要： 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.

    摘要： 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.

The channel equalizing unit corrects the distortion of the original signal due to a multipath and extracts the regenerative signal, thereby improving the quality of broadcasting repeating such as an image improvement of the repeated signal.
