<p>The present invention relates to a method of transmitting/receiving a signal and an apparatus for transmitting/receiving a signal. The present invention provides a method of transmitting a signal, including forward error correction encoding first program data and second program data, receiving identification information of the first program data and the second program data, and mapping the first and second program data to a first program data symbol and a second program data symbol using different symbol mapping methods according to identification information, forming a modulation frame including the first program data symbol, the second program data symbol, and a pilot symbol, modulating the formed modulation frame using an orthogonal frequency division multiplexing (OFDM) method and transmitting the modulated signal.</p> |
