COMMUNICATION APPARATUS AND COMMUNICATION METHOD

摘要

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 telephone RF unit 113 sends a receive invent to an event analysis processing unit 112. The event analysis processing unit 112 makes a request to a program information processing unit 104 for displaying the caption, and at the same time makes a request to an audio path switching control unit 109 for switching the audio path to the output side of a telephone audio processing unit 114. The program information processing unit 104 makes a multiplexed transmission separating unit 103 separate the caption and a caption/data broadcast processing unit 105 decodes separated caption data. A display superimposing unit 108 superimposes a decoded caption output onto a decoded video output, and a display output unit 110 displays it. When the user presses a call start/end button 116, a call start event is sent to the event analysis processing unit 112, and the event analysis processing unit 112 makes a call request to a telephone RF unit so as to start a call. When the user presses the call start/end button 116 to end the call, the event analysis processing unit 112 makes a call end request to the telephone RF unit 113 so as to end the call. The event analysis processing unit 112 at the same time makes a request to the audio path switching control unit 109 for switching the audio path to the side of a digital broadcast audio processing 107 so as to switch the audio path. The event analysis processing unit 112 also makes a request to the program information processing unit 104 for ending the separation of the caption so as to end the separation of the caption.
