APPARATUS AND A METHOD FOR CONVERTING A FREQUENCY OF A RADIO DATA SYSTEM, CAPABLE OF WATCHING A BROADCAST WITHOUT DISCONNECTION DURING TUNING TIME

摘要

PURPOSE: An apparatus and a method for converting a frequency of a radio data system are provided to prevent sound disconnection due to mute.;CONSTITUTION: A signal strength sensing unit(120) grasps broadcast frequency signal strength of an RDS(Radio Data System) which currently receives data. An audio controller(170) grasps a broadcast receiving quality state of an RDS which presently receives data through detected broadcast frequency signal strength. The audio controller determines whether to switch into an alternative frequency according to the grasped RDS broadcasting receive quality state. The audio controller controls output of an audio signal without mute in switching a frequency.;COPYRIGHT KIPO 2010
