Abstract
The present invention provides a method for transmitting a broadcasting signal. The method for transmitting the broadcasting signal according to the present invention comprises the steps of: encoding data of a plurality of PLPs according to a code rate, wherein the step of encoding data of a plurality of PLPs comprises the steps of LDPC-encoding data of at least one PLP of the plurality of PLPs according to the code rate, bit-interleaving the LDPC-encoded data, and mapping the bit-interleaved data to constellation; mapping the encoded data of the plurality of PLPs to generate at least one signal frame; and modulating data of the generated signal frame through an OFDM scheme and transmitting a broadcasting signal including the modulated data of the signal frame.
