Abstract: A method of transmitting a broadcasting signal is provided. The method includes encoding data; encoding signaling data by an LDPC (Low Density Parity Check) scheme; building a signal frame based on at least one preamble data symbol having the encoded signaling data and a data slice having the encoded data; inserting at least one pilot into the signal frame with a specific pattern and modulating the signal frame by an OFDM (Orthogonal Frequency Division Multiplexing) method; and transmitting the modulated signal frame. A signaling block having the signaling data is repeated in the at least one preamble data symbol in a frequency domain by a bandwidth. The bandwidth of the signaling block corresponds to a number of active subcarriers assigned to a single channel.
