JP 2001-339648 A

  By using a mobile phone (hereinafter referred to simply as “mobile phone”) that can receive a television broadcast program (hereinafter referred to as “program”), the user can view the program anytime and anywhere. Such television broadcasting includes digital television broadcasting in addition to analog television broadcasting. In particular, one-segment broadcasting in digital television broadcasting is generally intended for reception by a mobile body and is therefore suitable for a mobile phone. In addition, a display such as an LCD (Liquid Crystal Display) and a speaker, which are originally provided in a mobile phone, can be used for viewing a program. Parts can be shared and a portable television receiver can be supplied at low cost. In addition, since it has a communication function, a merit by the fusion of broadcasting and communication is also expected.

  Under such circumstances, the present inventor has come to recognize the following problems. When making a call using a mobile phone, a user generally uses a microphone and a speaker built in the mobile phone. At that time, the user cannot see the display. This makes it difficult for the user to view the program while making a call. In other words, if there is an incoming call while the user is watching the program with the mobile phone, the user stops watching the program and responds to the incoming call, or ignores the incoming call and views the program. Make a call after completion. On the other hand, if audio and video are output by a device other than the built-in microphone and speaker, there is a possibility that calling and viewing can be performed simultaneously. Therefore, if the output destination of the program automatically changes according to the connection status of devices other than the built-in microphone and speaker, the convenience for the user is improved.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide an output destination switching method for switching an output destination while considering an audio output destination and a program output destination in a call, and a communication apparatus using the output destination switching method. Is to provide.

  In order to solve the above-described problems, a communication device according to an aspect of the present invention includes a call unit that makes a call with a predetermined communication device, a voice output unit that outputs voice in a call in the call unit, and an output from the voice output unit. A receiving unit that receives a program that includes a sound to be transmitted and that is being broadcast, and a candidate for an output destination when the audio included in the program received by the receiving unit is output from the audio output unit A detecting unit. In the audio output unit, if the call unit receives an incoming call from the communication device and outputs the audio included in the program, the audio output unit is included in the program based on the output destination candidates detected in the detection unit. Determine the output destination of the audio.

  “Program” refers to a program that is being broadcast, but here the content is also included. That is, the program may indicate broadcast audio, broadcast video, and combinations thereof.

  According to this aspect, since the audio output destination candidate included in the program is detected and then the audio output destination included in the program is determined, if the audio output destination candidate included in the program can be detected The voice included in the program can be output while making a call.

  If there is only one output destination candidate detected by the detection unit, the audio output unit may stop outputting the audio included in the program when the call unit receives an incoming call from the communication device. In this case, since the output of the audio included in the program is stopped, a call can be executed.

  In the audio output unit, if there is only one output destination detected by the detection unit, when the call unit receives an incoming call from the communication device, the voice included in the program is synthesized with the voice in the call. It may be output. In this case, since the voice included in the program and the voice of the call are output while being synthesized, the voice included in the program can be output even if there is one output destination candidate.

  In the audio output unit, if there are a plurality of output destination candidates detected by the detection unit, the voice included in the program from any of the plurality of output destination candidates is received when the call unit receives an incoming call from the communication device. The voice of the call may be output from the remaining output destination candidates. In this case, since the audio included in the program and the audio in the call are output from each of the plurality of output destination candidates, they can be output without interfering with each other.

  A built-in loudspeaker and an external loudspeaker may be included as output destination candidates detected by the detection unit. “Built-in loudspeaker” refers to a speaker built in the communication device, and “external loudspeaker” refers to an earphone, a headphone, and a speaker connected to the communication device.

  The external loudspeaker as an output destination candidate detected by the detection unit is an earphone, and the voice output unit outputs the voice included in the program from the built-in loudspeaker, and outputs the voice of the call from the earphone. May be. In this case, the user can hear the voice included in the program while using the built-in loudspeaker, and can hear the voice in the call while using the earphone.

  The external loudspeaker as an output destination candidate detected by the detection unit is a loudspeaker provided in a predetermined external device, and the audio output unit is included in the program from the loudspeaker provided in the predetermined external device. The voice of the telephone call may be output from a built-in loudspeaker. The “predetermined external device” may include a display device including a speaker and may have a function of outputting sound. In this case, the user can hear the voice included in the program while using the loudspeaker provided in the external device, and can hear the voice in the call while using the built-in loudspeaker.

  Another aspect of the present invention is an output destination switching method. This method is an output destination switching method in a communication device having a function of making a call with a predetermined communication device and a function of receiving a broadcasted program, and outputs audio included in the received program. If an output destination candidate is detected and an incoming call from a communication device is received, the audio included in the program is output based on the detected output destination candidate. Determine the output destination.

  Yet another embodiment of the present invention is also an output destination switching method. A step of making a call with a predetermined communication device, a step of outputting sound in a call in the step of making a call, and a step of receiving a broadcast program that includes a sound to be outputted from the outputting step And a step of detecting a candidate for an output destination when the sound included in the received program is output in the step of outputting. In the outputting step, if the voice included in the program is output when an incoming call from the communication device is received, the voice included in the program based on the output destination candidate detected in the detecting step Determine the output destination.

  In the outputting step, if there is only one output destination candidate detected in the detecting step, the output of the audio included in the program may be stopped when an incoming call from the communication apparatus is received. In the outputting step, if there is only one candidate output destination detected in the detecting step, when the incoming call from the communication device is received, the output included in the program is synthesized with the voice in the call. May be. In the outputting step, if there are a plurality of output destination candidates detected in the detecting step, the voice included in the program is output from any of the plurality of output destination candidates when receiving an incoming call from the communication device. The voice of the call may be output from the remaining plurality of output destination candidates.

  A built-in loudspeaker and an external loudspeaker may be included as output destination candidates detected in the detecting step. The external loudspeaker as an output destination candidate detected in the detecting step is an earphone, and the outputting step outputs the voice included in the program from the built-in loudspeaker, and the voice in the call from the earphone. It may be output. The external loudspeaker as the output destination candidate detected in the detecting step is a loudspeaker provided in a predetermined external device, and the outputting step is performed from the loudspeaker provided in the predetermined external device to the program. The included voice may be output, and the voice in a call may be output from a built-in loudspeaker.

  It should be noted that any combination of the above-described constituent elements and a conversion of the expression of the present invention between a method, an apparatus, a system, a recording medium, a computer program, etc. are also effective as an aspect of the present invention.

  According to the present invention, it is possible to switch the output destination while considering the audio output destination and the program output destination in a call.

  Before describing the present invention in detail, an outline will be described. An embodiment of the present invention relates to a mobile phone (hereinafter referred to as “communication device”) capable of receiving a program. The communication apparatus according to the present embodiment incorporates a speaker for outputting audio in a call and outputting audio included in a program (hereinafter, such a speaker is referred to as “built-in speaker”). A microphone is built in for input (hereinafter, such a microphone is referred to as “built-in microphone”). Further, the communication device incorporates an LCD for displaying predetermined information and displaying a video included in the program. That is, since these constituent elements built in the communication device are used for viewing and calling a program, it is difficult to simultaneously execute the viewing and calling of the program. On the other hand, if the earphone microphone is connected to the communication device, there are a plurality of audio output destinations, so that it is possible to simultaneously view the program and call. When there is an incoming call while watching a program, the communication device executes the following processing in order to simplify the user operation.

  If there is an incoming call, the communication device checks whether the earphone microphone is connected. If the earphone microphone is connected, the communication device executes a call process using the earphone microphone, and outputs the sound included in the program from the built-in speaker. On the LCD, the output of the video included in the program is continued. As a result, it is possible to simultaneously perform program viewing and calling. On the other hand, if the earphone microphone is not connected, the communication apparatus executes a call process using the built-in speaker and the built-in microphone, and stops outputting the program. As a result, program viewing and calling are not executed simultaneously. In other words, if there is an incoming call while watching a program, the communication device automatically determines whether the call can be made while continuing to watch the program based on the connection status of the earphone microphone, etc. Appropriately set the device to be used for input / output As a result, user operations are also simplified.

  FIG. 1 is a diagram illustrating an appearance of a communication device 100 according to an embodiment of the present invention. The communication device 100 includes an LCD 10, a built-in speaker 12, a built-in microphone 14, an operation unit 16, an earphone microphone connection unit 18, and an output device connection unit 20. In addition, the communication device 100 connects the earphone microphone 22 and the external display device 28. The earphone microphone 22 includes an external microphone 24 and an external earphone 26, and the external display device 28 includes an external speaker 30 and an external display unit 32.

  Although the communication apparatus 100 shows a mobile phone having a folding mechanism, the communication apparatus 100 is not limited to this and may have other shapes. The LCD 10 displays video included in the program and predetermined information. The predetermined information includes a telephone number when receiving an incoming call. The built-in speaker 12 outputs the voice included in the program and the voice in a call. The built-in microphone 14 inputs voice in a call. Note that the built-in speaker 12 and the built-in microphone 14 are used in combination when performing a call. That is, it is assumed that both the built-in speaker 12 and the built-in microphone 14 are used for a call or are not used. The operation unit 16 is a button or the like on which a predetermined instruction is input by the user. The operation unit 16 may include a predetermined dial in addition to the buttons.

  The earphone microphone connection unit 18 connects an earphone microphone 22 that exists outside the communication apparatus 100. The external microphone 24 included in the earphone microphone 22 has a function of inputting sound, and the external earphone 26 included in the earphone microphone 22 has a function of outputting sound. The earphone microphone 22 is used in a call and is used to output sound included in a program. Therefore, the earphone microphone connection unit 18 connects an external audio output device such as the external earphone 26, a headphone (not shown), a speaker device (not shown), and outputs a sound signal corresponding to the external sound output device. The earphone microphone connection unit 18 connects an external audio input device such as an external microphone 24 and inputs an audio signal.

  The output device connection unit 20 connects an external display device 28 that exists outside the communication device 100. The external speaker 30 included in the external display device 28 has a function of outputting sound, and the external display unit 32 included in the external display device 28 has a function of outputting video. The external speaker 30 is used for outputting audio included in the program. The external display unit 32 is used to display video included in the program. Therefore, the output device connection unit 20 is connected to an external display device 28, a home television (not shown), a display for a personal computer (not shown), a display of a car navigation device (not shown), a liquid crystal projector (not shown), and the like. Send a signal according to. Here, the signal includes a signal related to video and a signal related to audio.

  As shown in the figure, the communication device 100 connects the earphone microphone 22 and the external display device 28, so that the communication device 100 can output voice in a call from the built-in speaker 12 and the external earphone 26, and the built-in microphone 14, Input from an external microphone 24 is possible. In addition, audio included in the program can be output from the built-in speaker 12, the external earphone 26, and the external speaker 30. Furthermore, the video included in the program can be displayed from the LCD 10 and the external display unit 32. As described above, since a plurality of candidates are provided as targets to which audio and video are to be input and output, it is possible to simultaneously perform program viewing and telephone conversation. Moreover, the communication apparatus 100 does not necessarily need to connect the earphone microphone 22 and the external display apparatus 28, and it is not necessary to connect one or both of them. The communication device 100 automatically switches the target to be used for calling and watching a program according to the connection status of the earphone microphone 22 and the external display device 28. The function for switching will be described below.

  FIG. 2 shows the configuration of the communication apparatus 100. The communication apparatus 100 includes a broadcast antenna 40, a broadcast receiving unit 42, a descrambler 44, a DEMUX (Demultiplexer) 46, a communication antenna 48, a communication unit 50, a central control unit 52, a display processing unit 54, and an audio processing unit 56. . Communication device 100 also includes output device connection unit 20 from LCD 10 shown in FIG. The display processing unit 54 includes a video decoder 58, a drawing unit 60, and a display control unit 62. The audio processing unit 56 includes an audio decoder 64, an audio output control unit 66, and an audio input control unit 68, and is connected to an earphone microphone. The unit 18 includes an audio output device connection unit 70 and an audio input device connection unit 72.

  The broadcast receiving unit 42 receives radio waves of a digital television broadcast being broadcast via the broadcast antenna 40. The radio wave includes a program. Furthermore, the broadcast receiving unit 42 has a tuner function, and by fixing the tuner reception frequency to a predetermined value, the broadcast receiving unit 42 uses the channel corresponding to the broadcast station to be viewed from the received radio wave. Select the program. That is, the broadcast receiving unit 42 demodulates the received radio wave by the functions of the tuner and the demodulator and converts it into TS (Transport Stream) data. Here, although the broadcast receiving part 42 demonstrates as what respond | corresponds to digital television broadcast, you may respond | correspond to analog television broadcast besides this. The channel setting in the broadcast receiving unit 42 is made based on a user instruction received from the operation unit 16.

  The descrambler 44 releases the scramble applied to the TS data output from the broadcast receiving unit 42. The DEMUX 46 analyzes the content of the encoded data based on the header information in the descrambled TS data. That is, the descrambled TS data has header information arranged at the head portion, followed by multiplexed encoded data. The multiplexed encoded data corresponds to video data, audio data, additional data, or a combination thereof. The DEMUX 46 divides the multiplexed encoded data into video data, audio data, and additional data based on the analysis result of the encoded data. Here, the audio data and the video data are encoded, that is, compressed in a format standardized by broadcasting. The additional data includes information other than video and audio, such as subtitles.

  The communication unit 50 communicates with a base station apparatus (not shown) via the communication antenna 48. Furthermore, the communication unit 50 performs a call with a communication device (not shown) via the base station device. The communication unit 50 includes a function corresponding to a communication system applied to the communication unit 50 and the base station device. Here, the communication system includes a mobile phone system, a second generation cordless phone system, and a third generation mobile phone system. Since the function according to these may be a well-known technique, description is abbreviate | omitted. The operation unit 16 receives a predetermined instruction from the user.

  The central control unit 52 controls input / output of predetermined data. That is, data input from the DEMUX 46, data input / output to / from the communication unit 50, data input from the operation unit 16, data output to the display processing unit 54, input to the audio processing unit 56 The input / output of data is switched so as to realize a predetermined function for the output data. Hereinafter, when a predetermined function is described, data transmission between a component that is a data transmission source and a component that is a data reception destination will be described. Is realized.

  The audio decoder 64 decodes audio data. Here, since the audio data is encoded by AAC, the video decoder 58 corresponds to an AAC decoder. The audio decoder 64 outputs the decoded audio data to the audio output control unit 66.

  The audio output control unit 66 switches the output destination when outputting audio. Note that the voice includes the voice included in the program and the voice in a call. The display control unit 62 and the voice input control unit 68 described later have the same function. As illustrated in FIG. 1, the output destination candidates include the built-in speaker 12, the earphone microphone connection unit 18, and the output device connection unit 20. Of the earphone / microphone connection unit 18, the audio output device connection unit 70 is used to output audio. The sound output control unit 66 detects a sound output destination candidate. For example, the built-in speaker 12, the earphone microphone connection unit 18, and the output device connection unit 20 may all be candidates, or the built-in speaker 12 and the earphone microphone connection unit 18 may be candidates, and only the built-in speaker 12 is a candidate. Sometimes it becomes. Here, the case where the earphone microphone connection unit 18 is an output destination candidate corresponds to the connection of the earphone microphone 22 of FIG. 1 to the earphone microphone connection unit 18. The audio output control unit 66 detects the connection of the earphone microphone 22 by measuring the impedance. The output device connection unit 20 may be the same.

  When the audio output control unit 66 outputs the audio included in the program and outputs the audio in the call, the output destinations of the audio included in the program and the audio in the call are the audio output control unit 66 in advance. The regulation may be stored in the audio output control unit 66 as fixed information, or may be input via the operation unit 16 by the user. Here, the latter case will be described. When the user inputs data while using the operation unit 16, the LCD 10 displays the input data. FIG. 3 shows a setting screen displayed on the LCD 10. “When the earphone microphone is connected” corresponds to the case where the earphone microphone connecting unit 18 is a candidate, and “when the output device is connected” is when the output device connecting unit 20 is a candidate. “When not connected” corresponds to the case where only the built-in speaker 12 is a candidate. “TV audio” indicates the output destination of the audio included in the program, and “call audio” indicates the output destination of the audio in the call. As shown in the figure, “TV sound” in “when an earphone microphone is connected” includes an earphone microphone and a speaker.

  The user selects one of the earphone microphone and the speaker while using the operation unit 16. If the earphone microphone is selected, the voice output control unit 66 uses the earphone as an output destination of the voice included in the program when the voice in the call is also output in “when the earphone microphone is connected”. The microphone connection unit 18 is selected. On the other hand, if the speaker is selected, the built-in speaker 12 is selected in the above case. The same applies to “when an output device is connected” and “call voice”. “Priority” indicates the order in which the above selection operations are executed. As shown in the figure, the priority is set to be higher when “earphone microphone is connected”, and the priority is set to be lower when “not connected”. Therefore, first, selection corresponding to “when the earphone microphone is connected” is executed. When it does not correspond to “when the earphone microphone is connected”, that is, when the earphone microphone connecting unit 18 is not set as an output destination candidate, the selection corresponding to “when the output device is connected” is executed. The

  Data stored in the audio output control unit 66 by the data input as described above will be described. FIG. 4 shows the structure of data stored in the audio output control unit 66. Here, the output destination of the audio included in the program to be selected by the audio output control unit 66 when the audio in the call is being output is defined. “Audio output device” indicates a candidate for an output destination of audio connected to the communication device 100 in addition to the built-in speaker 12. “None” corresponds to a case where there is no audio output destination candidate other than the built-in speaker 12. The “earphone / microphone connection unit” corresponds to a case where the earphone / microphone connection unit 18 is a candidate for an audio output destination. The “output device control unit” corresponds to a case where the output device connection unit 20 is a candidate for an audio output destination. The “output destination” indicates the output destination of the audio included in the program when an output destination candidate is connected to the “audio output device”. For example, when the earphone / microphone connection unit 18 is an output destination candidate, the audio included in the program is output to the built-in speaker 12. The “priority order” is the same as in FIG.

  Returning to FIG. The operation of the audio output control unit 66 having the above settings will be described. In the audio output control unit 66, if the communication unit 50 receives an incoming call from the communication device and outputs the audio included in the program, the audio output control unit 66 determines whether the audio included in the program is Determine the output destination. Here, if there are a plurality of detected output destination candidates, the audio output control unit 66 outputs the audio included in the program from any of the plurality of output destination candidates, and from the remaining plurality of output destination candidates. Outputs voice in a call. The audio output control unit 66 first confirms whether the earphone microphone connection unit 18 is included as an output destination candidate. That is, it is determined whether or not the earphone microphone 22 is connected.

  When the earphone microphone connection unit 18 is included, the earphone microphone connection unit 18 and the built-in speaker 12 correspond to output destination candidates. In this case, the audio output control unit 66 starts the call process while continuing to output the audio included in the program. The audio output control unit 66 outputs audio included in the program from the built-in speaker 12 and outputs audio in a call from the earphone microphone connection unit 18 in accordance with the regulations. Unlike this, only the earphone microphone connection unit 18 may synthesize and output the voice included in the program and the voice in the call. In this case, in order to make it easier to hear the voice in the call, the volume of the voice included in the program may be made smaller than in the case where the voice in the call is not output. That is, in the audio output control unit 66, when the audio included in the program and the audio in the call are synthesized, they may be synthesized so that the respective volumes are different. Note that the display control unit 62, which will be described later, displays the call information such as the call time on the LCD 10 in combination with the video included in the program.

  Next, the audio output control unit 66 confirms whether the output device connection unit 20 is included as an output destination candidate. That is, it is determined whether or not the external display device 28 is connected. As described above, the external display device 28 includes the external speaker 30. When the output device connection unit 20 is included, the output device connection unit 20 and the built-in speaker 12 correspond to output destination candidates. Also in this case, the audio output control unit 66 starts the call process while continuing to output the audio included in the program. The audio output control unit 66 outputs the audio included in the program from the output device connection unit 20 in accordance with the regulations, and outputs the audio in the call from the built-in speaker 12. The display control unit 62 described later causes the LCD 10 to display the call information such as the call time on the external display unit 32 so as not to prevent viewing of the program on the external display device 28.

  Following the above operation, if there is one detected output destination candidate, that is, the built-in speaker 12, the audio output control unit 66 operates as follows according to the regulations. If the output destination of the audio included in the program is set to the built-in speaker 12, the audio output control unit 66 starts a call while continuing to output the audio included in the program. That is, the sound output control unit 66 outputs the sound included in the program and the sound of the telephone call while being synthesized. At that time, the audio output control unit 66 increases the volume output from the built-in speaker 12. Further, the voice input control unit 68 described later sets the sensitivity of the built-in microphone 14 high. With these settings, a call with the main body of the communication device 100 separated from the user, that is, a so-called hands-free call can be performed. On the other hand, the display control unit 62 described later synthesizes and displays the call information and the video included in the program on the LCD 10.

  On the other hand, if the setting is made so that the audio included in the program is not output, the audio output control unit 66 stops outputting the audio included in the program and starts outputting the audio in the call. That is, call processing is started. Note that the operation of the DEMUX 46 is continued from the broadcast receiving unit 42 so that the program output by the audio output control unit 66 and the display control unit 62 is stopped so that viewing of the program can be resumed immediately after the call ends. Also good. In this case, it is possible to quickly resume the output of the program after the call is finished.

  In other words, in the above operation, when the sound output control unit 66 detects the earphone microphone connection unit 18 as an output destination candidate, the audio output control unit 66 executes a rule for the earphone microphone connection unit 18 and sets the earphone microphone connection unit 18 as an output destination candidate. If not detected, the output device connection unit 20 is detected. If the output device connection unit 20 is detected as an output destination candidate, the audio output control unit 66 executes the regulation for the output device connection unit 20, and if the output device connection unit 20 is not detected as an output destination candidate, the output is performed. The definition when the previous candidate is the built-in speaker 12 is executed.

  The built-in speaker 12, the output device connection unit 20, and the earphone microphone connection unit 18 output the sound output from the sound output control unit 66. As described above, the voice includes the voice included in the program and the voice in a call. Here, the earphone / microphone connection unit 18 includes an audio output device connection unit 70 and an audio input device connection unit 72, and the audio output device connection unit 70 is used for outputting audio. The output device connection unit 20 outputs sound to the external speaker 30, and the sound output device connection unit 70 outputs sound to the external earphone 26.

  The voice input control unit 68 selects either the built-in microphone 14 or the earphone microphone connection unit 18 as a voice input source, and outputs the input voice to the central control unit 52. The voice controlled by the voice input control unit 68 corresponds to the voice in a call. The selection in the voice input control unit 68 is a selection in the voice output control unit 66 and is executed so as to correspond to the selection of the voice output destination in the call. That is, the audio output control unit 66 selects the audio input source so as to correspond to the audio output destination in the call at the audio output control unit 66. For example, if the audio output control unit 66 selects the built-in speaker 12, the audio input control unit 68 selects the built-in microphone 14, and if the audio output control unit 66 selects the earphone microphone connection unit 18, the audio input control unit 68. Also, the earphone microphone connection unit 18 is selected. Here, the voice input control unit 68 uses the voice input device connection unit 72 of the earphone microphone connection unit 18. For the above selection, the voice input control unit 68 may accept the selection result in the voice output control unit 66.

  The video decoder 58 decodes the video data. Here, since the video data is encoded by MPEG (Motion Picture Experts Group), the video decoder 58 corresponds to an MPEG decoder. The video decoder 58 outputs the decoded video data to the display control unit 62.

  The drawing unit 60 generates predetermined information to be displayed. In order to generate predetermined information, additional data included in the program is used. In addition, the drawing unit 60 displays the incoming call information in association with the operation of the communication unit 50 together with the central control unit 52. In the incoming call information display, the telephone number of the caller is displayed. When the communication unit 50 detects an incoming call, the central control unit 52 and the drawing unit 60 display incoming call information. The central control unit 52 acquires the telephone number of the caller from the communication unit 50, and refers to the address book of a mobile phone (not shown) based on this. When the central control unit 52 detects data such as a name that matches the telephone number, the central control unit 52 acquires the data. The drawing unit 60 generates incoming call information by combining a character such as “incoming call” indicating that there is a voice incoming call and a name.

  If the corresponding data cannot be detected from the address book, the central control unit 52 generates incoming information from the telephone number instead of the name. The drawing unit 60 acquires font information corresponding to the character code of the incoming call information from a font area (not shown). The drawing unit 60 outputs the generated incoming call information to the display control unit 62. When the central control unit 52 detects that the button on the operation unit 16 is pressed, the communication unit 50 starts a call start process. On the other hand, the central control unit 52 waits for an instruction to start a call such as pressing a button until the end of the incoming call, but when the incoming call ends without receiving an instruction to start the call, the drawing unit 60 indicates that the incoming call has been received. Information is generated and output to the display control unit 62.

  The display control unit 62 selects either the LCD 10 or the output device connection unit 20 as an output destination of the video included in the program and the information generated in the drawing unit 60, and the video included in the program and the drawing unit 60. Output the information generated at. Here, the output destination of the video included in the program and the information generated in the drawing unit 60 may be different. Moreover, although it may be the same, the video included in the program and the information generated in the drawing unit 60 are combined at that time. The selection in the display control unit 62 is performed in a manner corresponding to the selection in the audio output control unit 66 and the output destination of the audio included in the program. That is, the display control unit 62 selects the output destination of the video included in the program so as to correspond to the output destination of the audio included in the program in the audio output control unit 66. For example, if the audio output control unit 66 selects the built-in speaker 12, the display control unit 62 selects the LCD 10, and if the audio output control unit 66 selects the output device connection unit 20, the display control unit 62 also connects to the output device. Section 20 is selected. For the above selection, the display control unit 62 may accept the selection result in the audio output control unit 66.

  The LCD 10 and the output device connection unit 20 output the video and information output from the display control unit 62. The output device connection unit 20 performs display on the external display unit 32. Here, an organic EL display or the like may be used instead of the LCD 10.

  This configuration can be realized in terms of hardware by a CPU, memory, or other LSI of an arbitrary computer, and in terms of software, it is realized by a program having a reservation management function loaded in memory. The functional block realized by those cooperation is drawn. Accordingly, those skilled in the art will understand that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof.

  The operation of the communication apparatus 100 having the above configuration will be described. FIG. 5 is a flowchart showing an incoming call procedure in the communication apparatus 100. The broadcast receiving unit 42 receives a program. The display control unit 62 and the audio output control unit 66 output a program via the video decoder 58, the audio decoder 64, and the like (S10). The communication unit 50 receives an incoming call (S12). The central control unit 52 and the drawing unit 60 generate incoming information from the telephone number corresponding to the incoming caller (S14). The display control unit 62 displays incoming call information (S16). If the incoming call in the communication unit 50 is finished (Y in S18), the process is finished. On the other hand, if the incoming call in the communication unit 50 does not end (N in S18) and there is an instruction to start a call from the operation unit 16 (Y in S20), the display processing unit 54, the voice processing unit 56, etc. Is executed (S22). The call start process will be described in detail below. If there is no instruction to start a call from the operation unit 16 (N in S20), the process returns to step 18.

  FIG. 6 is a flowchart showing the procedure of the call start process. This corresponds to step 22 in FIG. If the sound output control unit 66 detects that the earphone microphone 22 is connected to the earphone microphone connection unit 18 (Y of S50), the sound output control unit 66 outputs the sound in the call to the earphone microphone connection unit 18. , The audio output included in the program is set to the built-in speaker 12, and the audio input control unit 68 sets the audio input in the call to the earphone microphone connection unit 18 (S52). Further, the display control unit 62 sets the output of the video included in the program on the LCD 10.

  The audio output control unit 66 does not detect that the earphone microphone 22 is connected to the earphone microphone connection unit 18 (N in S50), and an output device such as the external display device 28 is connected to the output device connection unit 20. If it is detected (Y in S54), the audio output control unit 66 sets the audio output in the call to the built-in speaker 12 and sets the audio output included in the program to the external speaker 30 to generate the audio. The input control unit 68 sets the voice input in the call to the built-in microphone 14 (S56). Further, the display control unit 62 sets the display of the video included in the program on the external display unit 32 and sets the display of the call information on the LCD 10.

  The audio output control unit 66 does not detect that an output device such as the external display device 28 is connected to the output device connection unit 20 (N in S54), and the audio output control unit 66 is set to continue viewing. If this is the case (Y in S58), the audio output control unit 66 sets the audio output in the call and the audio output included in the program to the built-in speaker 12, and the audio input control unit 68 sets the audio output in the call. The input is set to the built-in microphone 14 (S60). The audio output control unit 66 is set so that the volume of the built-in speaker 12 is increased, and the audio input control unit 68 is set so that the sensitivity of the built-in microphone 14 is increased. Further, the display control unit 62 sets the display of the video included in the program and the display of the call information on the LCD 10.

  If the setting for continuing viewing is not set in the audio output control unit 66 (N in S58), the audio output control unit 66 sets the audio output in the call to the built-in speaker 12, but outputs the audio included in the program. The voice input control unit 68 sets the voice input in the call to the built-in microphone 14 (S62). The communication unit 50 or the like executes voice call processing (S64).

  According to the embodiment of the present invention, since the audio output destination candidate included in the program is detected and then the audio output destination included in the program is determined, a call is executed according to the detection result. However, the audio included in the program can be output. Further, even when an output destination candidate is connected to or removed from the communication apparatus, the output destination can be automatically determined. In addition, since the output destination is automatically determined, the convenience for the user can be improved. Also, in order to determine the output destination, priority is given to the candidates for the output destination, and the process for determining the output destination is executed according to the priority order. Can be easily determined. Further, since the processing is executed according to the priority order, the processing can be executed step by step, and the output destination intended by the user can be determined.

  In addition, since the priority order and the output destination can be freely set, the intention of the user can be reflected. If there is only one output destination candidate, the output of the audio included in the program is stopped, so that the call can be executed with priority. In addition, since the voice included in the program and the voice of the call are output while being synthesized, the voice included in the program can be output even if there is one output destination candidate. In addition, since the audio included in the program and the audio in the call are output from each of the plurality of output destination candidates, the audio can be output without interfering with each other, and the user can simultaneously view and call the program. In addition, the user can listen to the voice included in the program while using the built-in speaker, and can hear the voice in the call while using the earphone.

  Further, the user can listen to the voice included in the program while using the external speaker provided in the external display device, and can listen to the voice in the call while using the built-in speaker. Further, by determining the output destination of the video included in the program while corresponding to the output destination of the audio included in the program, the user can view the program even while making a call. Also, by determining the input source of the voice in the call while corresponding to the output destination of the voice in the call, the user can execute the call even while watching the program.

  In the above, this invention was demonstrated based on the Example. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to the combination of each component and each processing process, and such modifications are also within the scope of the present invention. .

However, the present invention is not limited to this, and the priorities may be different. For example, the connection of the output device connection unit 20 may be confirmed, and if not connected, the connection of the earphone microphone connection unit 18 may be confirmed. Moreover, you may perform the choice only with respect to any one of the earphone microphone connection part 18, the output apparatus connection part 20, and no connection. For example, it may be determined only whether or not the earphone / microphone connection unit 18 is included in a candidate, and an output destination corresponding to the determination may be selected.

  Further, when starting a call, the user may select an output destination. For example, if an incoming call button is attached to the earphone microphone 22 and the user presses the incoming call button at the time of incoming call, a call using the earphone microphone 22 is started. When a call is made with the earphone microphone 22 and the call is started by the operation unit 16, the call is made with the built-in speaker 12 and the built-in microphone 14. According to this modification, the output destination can be selected in various forms. The same applies to video output and audio input. That is, a program may be output so as not to disturb the call.

  In the embodiment of the present invention, the audio output control unit 66 targets the built-in speaker 12, the earphone microphone connection unit 18, and the output device connection unit 20 as output destination candidates. However, the present invention is not limited thereto, and for example, the audio output control unit 66 may target the Bluetooth connection unit as an output destination candidate.
