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 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.

10. A communication apparatus comprising:
-
a multiplexed data receiving unit that receives multiplexed data including at least audio data; an extracting unit that extracts the audio data from the multiplexed data received by the multiplexed data receiving unit; a telephone unit that transmits/receives telephone audio data; and an audio output unit that outputs at least one of the audio data extracted by the extracting unit and the telephone audio data received by the telephone unit, wherein the telephone unit continues to transmit/receive the telephone audio data when an occurrence of an initiating event of the multiplexed data receiving unit receiving the multiplexed data is detected while the telephone audio data is being received by the telephone unit, wherein the audio output unit outputs the telephone audio data when the occurrence of the initiating event is detected while the telephone audio data is being received by the telephone unit, and wherein the multiplexed data receiving unit initiates receiving the multiplexed data when the occurrence of the initiating event is detected while the telephone audio data is being received by the telephone unit. - View Dependent Claims (11, 12, 13, 14, 15)
