Abstract

A hybrid terminal of a mobile phone and a digital broadcast receiver allows calling on the mobile phone while at the same time receiving a digital broadcast itself even in the event of receiving a call while at the same time receiving the digital broadcast. Upon receiving a call while at the same time receiving a digital broadcast, a caption within the digital broadcast is decoded and displayed. When the user presses a call start/end button, an analog path is switched to an audio telephone path so as to start a call and the broadcast caption is also decoded and displayed. When the user presses the call start/end button to end a call, the audio path is switched to a digital broadcast audio path, and decoding and display of the broadcast caption is stopped.
