[Problem] To provide a new terrestrial broadcasting system compatible with terrestrial digital television broadcasting. [Solution] Data for normal image quality reproduction and data for high quality image reproduction according to digital terrestrial television broadcasting are input to an input unit 21. The combining unit 22 combines the data for normal image quality reproduction and the data for high image quality reproduction. Then, based on the combined data obtained by combining the data for normal image quality reproduction and the data for high image quality reproduction by the combining unit 22, the data configuration unit 23 transmits the data for transmission of one polarization antenna and the other polarization data. And data for transmitting a wave antenna.
