Claim:
1. A method for transmitting broadcast signals, the method comprising: input processing input streams to output PLP (Physical Layer Pipe) data corresponding to PLPs; encoding preamble data carrying L1 (Layer 1) signaling information including channel bonding information for each PLP and identification information for identifying each PLP; encoding the PLP data by an LDPC scheme; QAM (Quadrature Amplitude Modulation) mapping the encoded PLP data; time interleaving the mapped PLP data; building signal frames, wherein at least one signal frame includes the encoded preamble data and data symbols including the time interleaved PLP data; modulating the built signal frame by an Orthogonal Frequency Division Multiplexing (OFDM) method; and transmitting the modulated signal frame.
