The invention concerns a method of transmitting a broadcasting signal, the method comprising: encoding physical layer pipe, PLP, data for conveying a service stream for forward encoding correction; mapping the encoded PLP data to data symbols according to a symbol mapping method ; building a frame including the data symbols modulating the frame by an orthogonal frequency divisional multiplexing scheme; and, inserting a first pilot, P1, symbol at a beginning part of the modulated frame, wherein the modulated frame includes a second pilot, P2, symbol having layer 1, L1, information being signaling information for the data symbols, and wherein the L1 information includes an index indicating a starting radio frequency, RF, channel of the frame.
