摘要

PURPOSE: A broadcasting receiving device and a broadcasting channel changing method using the same are provided to change a satellite broadcasting channel into a public wave broadcasting channel when receiving strength of the satellite broadcasting channel is smaller than reference receiving strength, thereby effectively reproducing the same program.;CONSTITUTION: A receiving strength measuring unit(118) measures receiving strength of a satellite broadcasting channel or a public wave broadcasting channel. A storage unit(116) stores channel change information for a broadcasting channel change. If the measured receiving strength is smaller than the reference receiving strength of the channel change information, a controller(104) changes a channel according to the channel change information.;COPYRIGHT KIPO 2010
