PURPOSE: An additional data transmitting/receiving apparatus is provided to compensate distortion in an RF (Radio Frequency) part in case additional information is inserted into a digital broadcast signal. CONSTITUTION: An insertion level control unit (133) determines a level for inserting modulated additional information into a digital TV broadcast signal.
