RELAY APPARATUS FOR TRANSMITTING ANCILLARY DATA FOR A TERRESTRIAL DIGITAL TELEVISION BROADCAST, AND METHOD FOR SAME |
摘要 |
The present invention relates to a relay apparatus for transmitting ancillary data and to a method for same, and particularly, to a relay apparatus for transmitting ancillary data for a terrestrial digital television broadcast and to a method for same. The apparatus according to one embodiment of the present invention comprises: a relay apparatus for relaying a digital broadcast (DTV) signal containing ancillary data; a receiving and processing unit for receiving the ancillary data and DTV signal via a receiving antenna, down-converting the received signal into an intermediate frequency (IF) signal, and demodulating the IF signal; an equalizing unit for removing noise and a multipath signal from the signal output from the receiving and processing unit, and outputting the resulting signal; an ancillary data extraction unit for extracting the ancillary data from the signal output from the equalizing unit, and outputting the extracted ancillary data; an adder for adding the output from the ancillary data extraction unit to the DTV signal output from the equalization unit; and a transmitting and processing unit for modulating the output from the adder, up-converting the modulated output into a transmitting RF band, amplifying the transmitting power, and transmitting the amplified power via a transmitting antenna. |
