Claim:
1. A method of transmitting at least one broadcasting signal having Physical Layer Pipe (PLP) data and preamble data, the method comprising: encoding the PLP data; outer encoding the preamble data; mapping the encoded PLP data into PLP data symbols by Quadrature Amplitude Modulation (QAM) modulations; mapping the encoded preamble data into preamble data symbols by QAM modulations; time interleaving the PLP data symbols which is symbol-mapped by the QAM modulations using a twisted block interleaving scheme, wherein the time interleaving is performed by using an interleaving memory, wherein positions of cells in the interleaving memory are acquired based on a twisting parameter and a modulo operation, wherein each cell with the PLP data symbols in the interleaving memory is accessed in a diagonal-wise direction corresponding to the twisting parameter and wherein specific cells of the interleaving memory are skipped during reading operation of the time interleaving; building a signal frame including the time interleaved PLP data symbols and the preamble data symbols, wherein the preamble data symbols include first signaling information for second signaling information and the second signaling information for the PLP data symbols, wherein the first signaling information includes size information of the second signaling information; modulating the signal frame by Inverse Fast Fourier Transform; and transmitting the modulated signal frame, wherein the preamble data further includes information for channel bonding, and wherein data-reordering is performed at a receiver side when the channel bonding is applied.
