Abstract

An apparatus and method for broadcast signal frame using a bootstrap including a symbol for signaling a BICM mode and OFDM parameters of a preamble, together are disclosed. An apparatus for generating broadcast signal frame according to an embodiment of the present invention includes a time interleaver configured to generate a time-interleaved signal by performing interleaving on a BICM output signal; and a frame builder configured to generate a broadcast signal frame including a bootstrap and a preamble using the time-interleaved signal. In this case, the bootstrap includes a symbol for signaling a BICM mode and OFDM parameters of L1-Basic of the preamble, together.
