Description

  The present invention relates to a communication apparatus having both a telephone function and a digital broadcast receiving function, and a communication method for performing telephone audio data transmission / reception processing and digital broadcast reception processing.

  The rapid spread of mobile phones is often attributed to the installation of functions other than the original call function such as a WEB browser and e-mail. In recent years, new functions such as Java (registered trademark) applications and TV phones have been installed on a daily basis.

  In Japan, digital satellite broadcasting services such as CS (Communication Satellite) and BS (Broadcasting Satellite) have already started, and digital broadcasting services are scheduled to start in 2003 for terrestrial broadcasting. In addition, terrestrial digital broadcast receiving terminals are also being developed for portable reception with partial reception, and are ready for the start of services.

  In the future, mobile phones are expected to have a digital broadcast receiving function in addition to WEB browsers and e-mails. However, at the present time, there is no prior art in the field that is the subject of the present invention.

  JP-A-6-165073 is cited as a reference technique.

  FIG. 8 shows a configuration diagram thereof. In the present invention, when the mute button is pressed by the remote control transmitter 9 or the main body keyboard 8, the mute process is performed, and at the same time, the caption decoder on / off control unit 10 turns on the caption decoder 3 and is multiplexed by the display processing unit 5. Caption data is displayed.

Conversely, when the mute release button is pressed with the remote control transmitter 9 or the main body keyboard 8 while the mute is on and the caption decoder is on, the mute release process is performed and at the same time the caption decoder on / off control unit 10 turns off the caption decoder 3. In this case, only the video is displayed by the display processing unit 5.

Further, the voice path is set on the telephone side by the voice path switching control unit 109.

  When the user presses the call / end call button 116, the event analysis processing unit 112 detects the end call event, transmits an instruction message (telephone voice data transmission / reception stop instruction) to the telephone RF unit 113, and makes a call. Terminate.

  When the conversation person (calling party) ends the conversation first, the telephone RF unit 113 raises the end event to the event analysis processing unit 112.

  At the same time, the event analysis processing unit 112 instructs the program information processing unit 104 to start separation of digital broadcast audio data (return of digital broadcast audio) and stop separation of subtitle data (deletion of subtitle broadcast). Further, the event analysis processing unit 112 transmits an instruction message (extracted audio data switching instruction) to the audio path switching control unit 109 to instruct to switch the audio path to the output side of the digital broadcast audio processing unit 107.

  The program information processing unit 104 transmits an instruction message (audio data extraction start instruction and character data extraction stop instruction) to the multiplex transmission separation unit 103 to start separation of digital broadcast audio data and stop separation of subtitle data. Instruct.

  The multiplex transmission separation unit 103 starts separation of digital broadcast audio data and stops separation of subtitle data, the digital broadcast audio processing unit 107 starts audio decoding processing, and the subtitle / data broadcast processing unit 105 decodes subtitle data. To stop.

  As a result, the display superimposing unit 108 displays only the video data output from the digital broadcast video processing unit 106 on the display output unit 110.

  The audio path switching control unit 109 that has received the instruction message by the event analysis processing unit 112 switches the audio path to the digital broadcast audio side, and outputs the audio data of the digital broadcast from the audio output unit 111.

In this case, since the voice output is switched to the extracted voice data, both reception and output of multiplexed data and a call can be realized.

  Further, according to the present invention, the display of the extracted character data is started when an incoming event or outgoing event occurs during reception of multiple data, and the extracted character data is displayed when a call end event occurs during reception of multiple data. Since the display of is stopped, the display time of the character data can be minimized.

  In addition, according to the present invention, when an incoming event or outgoing event occurs during reception of multiplexed data, voice output is performed with a loud voice, so that both reception and output of multiplexed data and a call can be realized in a hands-free manner. Can do.

  In addition, according to the present invention, when telephone voice data is transmitted / received at the time when multiplexed data reception is started, switching to extracted voice data is not performed, so that reception of multiplexed data is started during a call. Even so, it is possible to realize both reception and output of multiplexed data and a call.

  Further, according to the present invention, the vibrator is operated when telephone voice data is transmitted / received at the reception start time of the multiplexed data, so that the vibrator is activated even when reception of the multiplexed data is started during a call. Thus, the start of reception of multiplexed data can be notified.

3 is a diagram showing a configuration of a hybrid terminal of a mobile phone and a digital broadcast receiver according to Embodiment 1. FIG. The flowchart figure which shows the control flow at the time of the telephone call incoming. The figure which shows the event and state which an event analysis process part manages. FIG. 4 shows a configuration of a hybrid terminal of a mobile phone and a digital broadcast receiver according to a second embodiment. FIG. 9 shows a configuration of a hybrid terminal of a mobile phone and a digital broadcast receiver according to Embodiment 3. The flowchart figure which shows the control flow at the time of digital broadcast viewing start. FIG. 9 shows a configuration of a hybrid terminal of a mobile phone and a digital broadcast receiver according to a fourth embodiment. The figure which shows the prior art.
