Abstract:
An apparatus and method for broadcast signal frame using a bootstrap and a preamble 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.

Claim (Index 1):
A method of generating a broad signal frame, comprising:\n generating a time-interleaved signal by performing interleaving on a BICM (Bit-Interleaved Coded Modulation) output signal; and generating a broadcast signal frame including a bootstrap and a preamble using the time-interleaved signal, wherein the preamble includes L1-Basic and L1-Detail, and the bootstrap includes a symbol representing a structure of the L1-Basic, wherein the symbol corresponds to a fixed-length bit string signaling a signaling protection mode of the L1-Basic along with OFDM parameters of the L1-Basic, wherein the signaling protection mode includes\n a first mode, a second mode, and a third mode for identifying QPSK modulation and a code rate of 3/15, \n a fourth mode for identifying 16-NUC (Non Uniform Constellation) and a code rate of 3/15, and \n a fifth mode for identifying 64-NUC (Non Uniform Constellation) and a code rate of 3/15, \n wherein the first mode corresponds to a mode in which parity repetition is performed, and the second mode and the third mode correspond to a mode in which the parity repetition is not performed, and wherein a parity puncturing size of the second mode is larger than a parity puncturing size of the first mode and smaller than a parity puncturing size of the third mode.
