Abstract:
An apparatus for embedding additional information that may embed additional information into a digital television (TV) broadcast signal and transmit the additional information is provided. The apparatus may modulate the additional information to an intermediate frequency/radio frequency (IF/RF), embed the modulated additional information into the digital TV broadcast signal, and compensate for a distortion that may occur in an RF part, thereby correctly transmitting the additional information.
