Abstract
A broadcasting signal reception method according to the present invention comprises the following steps: OFDM-demodulating by receiving a plurality of broadcasting signals, which contain a transmission frame for transmitting a broadcasting service; outputting the transmission frame by decoding a plurality of OFDM-demodulated broadcasting signals with at least one method among MIMO, MISO, and SISO; and selectively decoding a plurality of PLP's, which are included in the transmission frame, using signaling information included in the transmission frame. In particular, PSI/SI such as PAT/PMT can be transmitted through an arbitrary PLP among the plurality of PLP's; and in the transmitter, an arbitrary PLP, which transmits the PAT/PMP, can be decoded first to enable a search of all PLP's that transmit components included in a single broadcasting service, and a plurality of PLP's can be decoded selectively.
