摘要

A mobile terminal (3) includes: a high-frequency reception unit (32) for receiving main broadcast data and sub broadcast data; a field intensity measurement unit (34) for measuring field intensity corresponding to the reception state in the high-frequency reception unit (32); a reception quality judgment unit (52) for judging the reception quality according to a comparison between the field intensity measured by the field intensity measurement unit (34) and a predetermined required quality threshold value; and a switching processing unit (54) for reproducing the main broadcast data corresponding to a specified channel if the reception quality is judged to be good by the reception quality judgment unit (52) and reproducing the sub broadcast data corresponding to the specified channel if the reception quality is judged to be bad by the reception quality judgment unit (52). This realizes a reception device eliminating the need of transmission/reception operation of the retransmission request, enabling effective utilization of the line, and improving the satisfaction of a viewer.
