Abstract: Disclosed is an apparatus for transmitting a broadcast signal, an apparatus for receiving a broadcast signal, and a method for transmitting/receiving a broadcast signal using an apparatus for transmitting/receiving broadcast signal. A method for transmitting a broadcast signal according to the present invention comprises the steps of: generating a first PLP which includes an IP stream having at least one service component; signaling IP-PLP mapping information for linking the IP stream and the PLP in binary form and generating a second PLP which includes the signaled binary information; performing FEC-encoding and bit-interleaving on the first and second PLPs; generating a transmission frame including the first and second bit-interleaved PLPs; and modulating the transmission frame and transmitting a broadcast signal including the modulated transmission frame, wherein the IP-PLP mapping information includes IP information for identifying the IP stream and PLP information for identifying the PLP.
