Broadcast signal transmitter/receiver, and broadcast signal transceiving method

摘要

Disclosed are a broadcast signal transmitter, a broadcast signal receiver, and a method for transceiving a broadcast signal in the broadcast signal transmitter/receiver. A method for transmitting a broadcast signal comprises the following steps: signaling in-band signaling information to at least one of a service component physical layer pipe (PLP) including at least one service component of a broadcast service, a first information PLP including first service information applied to one broadcast service and a second information PLP including second service information applied commonly to a variety of broadcast services; performing the FEC encoding on data included in each PLP; performing time-interleaving on the FEC encoded data; generating a transmission frame including the time-interleaved data; and modulating the transmission frame and transmitting a broadcast signal including the modulated transmission frame.

1. A method of transmitting a broadcast signal in a broadcast signal transmitter, the method comprising:
Forward Error Correction (FEC) encoding first layer data; FEC encoding second layer data; combining the FEC encoded first layer data and second layer data; building a frame including the combined FEC encoded first layer data and second layer data, and signaling data; inserting pilot data into the built frame; modulating data of the built frame by an Orthogonal Frequency Division Multiplexing (OFDM) method; inserting a first OFDM symbol and a second OFDM symbol in front of the modulated built frame in a time domain; and transmitting the broadcast signal including the built frame, wherein a postfix of the first OFDM symbol and a prefix of the second OFDM symbol are sequentially positioned in the time domain, wherein the signaling data includes type information for at least one physical layer pipe (PLP) of the first layer data, excluding at least one PLP of the second layer data.
