Abstract

A communication apparatus including 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, a telephone unit that transmits/receives telephone audio data, and an audio output unit that outputs at least one of the extracted audio data and the telephone audio data. The telephone unit continues to transmit/receive the telephone audio data when an occurrence of an initiating event of the multiplexed data receiving unit is detected while the telephone audio data is being received. 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. The multiplexed data receiving unit initiates receiving the multiplexed data when the occurrence of the initiating event is detected while the telephone audio is being received.

Claims

1. A communication apparatus comprising:

An extracting unit that extracts video data, text data and audio data from multiplexed data received by the extracting unit;

a telephone unit that transmits/receives telephone audio data;

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;

a display output unit configured to display the at least one of the video data and the text data from the extracting unit; and

an event analysis processing unit that detects an initiating event and whether or not the telephone unit currently transmits or receives the telephone audio data, wherein the event analysis processing unit instructs the telephone unit to continue to transmit/receive the telephone audio data, instructs the extracting unit to initiate receiving the multiplexed data, to begin extracting video data and text data and to stop extracting audio data instructs the audio output unit to output the telephone audio data path in place of the audio data extracted by the extracting unit, and instructs the display output unit to output both the video data and the text data in the form of a caption when detecting an occurrence of an initiating event of the extracting unit starting reception of the multiplexed data is while the telephone audio data is being received by the telephone unit.

2. The communication apparatus according to claim 1 further comprising:

a vibrator,

wherein the vibrator vibrates when the occurrence of the initiating event is detected while the telephone audio data is being transmitted/received by the telephone unit.

3. The communication apparatus according to claim 1, wherein the extracting unit continues to receive the multiplexed data, and the event analysis unit instructs the extracting unit to start extracting audio data and instructs the audio output unit to output the audio data and stop outputting telephone audio data when an occurrence of an end event is detected.

4. The communication apparatus according to claim 1, wherein the extracting unit continues to receive the multiplexed data, and the event analysis unit instructs the extracting unit to stop extracting the text data and instructs the display output unit to output the video data from the extracting unit when an occurrence of an end event is detected.

5. The communication apparatus according to claim 1, further comprising:

an audio path switching control unit that switches an input to the audio output unit between the audio data extracted by the extracting unit and the telephone audio data received by the telephone unit, wherein the event analysis processing unit instructs the audio path control unit to switch the input between the audio data extracted by the extracting unit and the telephone data received by the telephone unit based on whether or not the telephone unit currently transmits or receives the telephone audio data.

6. A wireless device for receiving digital broadcast signals and phone signals, the device comprising:

a digital broadcast tuner configured to receive digital broadcast signals;

a telephone device configured to transmit and receive telephone audio;

a multiplexed transmission separating unit, coupled to the digital broadcast tuner configured to separate digital broadcast signals into video, audio and text data streams;

a video processing unit that extracts video data from the video stream;

an audio processing unit that extracts audio data from the audio stream;

a text processing unit that extracts text data from the text data stream;

a display output unit configured to output at least one of video data or text data;

an audio output unit configured to output at least one of audio data from the audio processing unit and received telephone audio;

a reception preset processing unit configured to enable the digital broadcast tuner unit when a preset function starts a preset program reception;

an event analysis processing unit configured to instruct the video processing unit to extract video data, instruct the text processing unit to extract text data and output both video and text data through the display output unit, instruct the audio processing unit to stop extracting audio data and output the telephone audio through the audio output unit when the telephone unit is transmitting and receiving telephone audio.

7. The wireless device of claim 6, wherein the event analysis processing unit is further configured to instruct the text processing unit to stop extracting text data and output the video data through the video output unit and instruct the audio processing unit to start extracting audio data and output the audio data through the audio output unit when the telephone unit is not transmitting and receiving telephone audio.
