摘要

The present invention relates to a broadcasting transmission apparatus. Disclosed in the present specification is the broadcasting transmission apparatus which comprises an ATSC signal generation unit to transmit an ATSC signal in accordance with ATSC transmission standards; a low-speed data signal generation unit which has the same frequency range as that of the ATSC signal, and transmits at least one narrow-band signal located in a null frequency domain of an NTSC removal filter; a coupling unit to couple the ATSC signal to the at least one narrow-band signal; and an RF transmission unit to transmit the signal, coupled by the coupling unit, as an RF signal.
