  FIG. 3 is a block diagram showing a software configuration for the main control unit 20 to execute the TV viewing control process when a voice call is interrupted while watching the TV on the mobile phone 1. The mobile phone 1 has a framework 30 that includes software components for implementing application programs. On this framework 30, an application manager for managing activation and termination of all application programs and a stack. 31. A user interface for a TV function as well as a one-segment application 32 that is an application program for performing TV viewing processing, recording processing, and playback processing for a user. It has a call application 33 which is an application program for controlling.

  In addition, the mobile phone 1 has an operating system 34 under the framework 30 that controls a computer to make computer resources such as application programs and middleware available to the application program. The device management middleware 35, which is middleware for managing the state of the main body and the external device connected to the main body such as a headset, is positioned between the one seg application 32 and the operating system 34, and the television is transferred from the operating system 34 to the one seg application 32. One segment middleware 36 that is a middleware providing functions, located between the call application 33 and the operating system 34, and provides a call function from the operating system 34 to the call application 33. And a call middleware 37 is $ ware.

  In addition, the mobile phone 1 includes a device driver 38 that controls the hardware 39 under the operating system 34 and provides an interface abstracted to application programs and middleware. It has hardware 39 which is a physical component of the mobile phone 1.

  In many cases, the terrestrial digital television broadcast wave received by the mobile phone 1 includes subtitle information. The mobile phone 1 determines whether or not to display the subtitle information on the display 12 while watching TV according to user settings. The setting of can be switched. Furthermore, the mobile phone 1 is provided with a TV viewing control function for setting the audio of the TV broadcast to no sound and displaying subtitle information on the display 12 when an incoming voice call occurs while watching TV. ing. Note that the mobile phone 1 returns to the viewing state before the voice call is received after the call ends.

  When the mobile phone 1 receives a voice call while watching TV, the procedure for performing the TV watching control process is shown in the flowcharts shown in FIGS. 4 and 5, the screen transition diagram shown in FIG. This will be described based on the sequence diagram shown in FIG. 7 is a sequence diagram in the case where the program being viewed on the mobile phone 1 has caption information. FIG. 8 is a sequence diagram in which the program being viewed on the mobile phone 1 has caption information. It is a sequence diagram when there is no. Hereinafter, for example, “step S101” is described as “S101”, and the term “step” is omitted.

  First, it is assumed that the mobile phone 1 is performing TV viewing processing. At this time, on the display screen 40 of the display 12, for example, as shown in FIG. 6 (A), as shown in FIG. 6 (A), for example, as shown in FIG. A program information display field 41a in which video and text information of television broadcasting is displayed is displayed.

  In this state, the main control unit 20 determines whether an incoming voice call has occurred in the mobile phone 1 (S101). At this time, the main control unit 20 determines that there is an incoming voice call based on the fact that the call middleware 37 detects the incoming call signal. If no voice incoming call has occurred (No in S101), the main control unit 20 waits until a voice incoming call occurs.

  As shown in FIGS. 7 and 8, when a voice call occurs in the mobile phone 1, the call middleware 37 is watching the TV with respect to the application manager 31 (the 1Seg application is in the forefront (topmost)). An inquiry is made as to whether or not there is (S301), and the application manager 31 returns a signal indicating whether or not the TV is being watched to the call middleware 37 (S302). If the user was not watching, the normal voice incoming call processing was performed, such as notifying the user of the incoming voice by ringtone or vibration, and the TV was being watched when the voice incoming occurred. In this case, the following TV viewing control process is performed.

  When a voice call occurs in the mobile phone 1 (Yes in S101), the main control unit 20 determines whether or not the headset is used in the mobile phone 1 (S103). By using the headset, the user can make a call without putting the mobile phone 1 on the ear. Therefore, when the user is using a headset, both the TV viewing and the telephone call can be performed simultaneously with the mobile phone 1, so the main control unit 20 switches the audio output of the TV broadcast to subtitle display. Then, call processing starts while watching TV.

  At this time, as shown in FIGS. 7 and 8, the call middleware 37 makes an inquiry to the device management middleware 35 as to whether the headset is in use (S303), and the device management middleware 35 A signal indicating whether or not it is in use is returned to the call middleware 37 (S304).

  When the headset is used (Yes in S103), the main control unit 20 determines whether or not the program being viewed includes subtitle information in order to switch to subtitle information instead of audio (S105). ). At this time, the main control unit 20 determines the presence / absence of a caption based on a parameter (stream_type) in a PMT (Program Map Table) included in the terrestrial digital television broadcast wave.

  When the program being viewed with the TV viewing function includes caption information (Yes in S105), the main control unit 20 sets caption information to be present in the caption setting (S107). At this time, the call middleware 37 requests the one-segment middleware 36 to set “with caption display” (S305). The one-segment middleware 36 sets “with caption display” in the television viewing function (S306).

  Thereby, the subtitle information is displayed on the display 12 together with the video of the program. At this time, on the display screen 40 of the display 12, for example, as shown in FIG. 6C, a program information display column 42 for displaying video and a call information display column 43 for displaying call information are displayed. In the program information display field 42, caption information 44 is displayed. Alternatively, on the display screen 40 of the display 12, for example, as shown in FIG. 6D, a program information display column 42a for displaying video and a call information display column 43a for displaying call information are displayed. Subtitle information 44a is displayed in the program information display field 42a. The call information includes, for example, information related to the call partner, call time, and the like.

  The main control unit 20 stores the current setting information in the storage unit 23 (S109). At this time, the one-seg middleware 36 transmits a signal indicating that “subtitle display is set” to the one-seg application 32 (S307), and the one-seg application 32 that has received this signal stores the setting information in the storage unit 34. Store (S308). The stored setting information includes volume information, caption setting information, display layout information, and the like. The stored setting information is used to reset the television viewing function when the call processing is terminated.

  The main control unit 20 sets the volume setting to mute (S111). At this time, the one-segment middleware 36 sets the volume of the TV viewing function to mute and invalidates the sound (S309). Then, the one-segment middleware 36 returns a response indicating that the setting of “with caption display” is completed to the call middleware 37 (S310).

  Then, the main control unit 20 executes the television viewing function at the lower level (S113). That is, the main control unit 20 executes the call function at the upper level and executes the TV viewing function below it. At this time, the call middleware 37 transmits a signal for requesting an interrupt activation of the call application (“mode while watching one seg”) to the application manager 31 (S311). The application manager 31 that has received the signal transmits a signal for instructing the television viewing function to be interrupted to the one-segment application 32 (S312), and the one-segment application 32 interrupts the television viewing function (executed at a lower level). ) And a signal indicating the interruption is transmitted to the application manager 31 (S313). Note that the “mode while watching 1Seg” is an operation mode that does not hide the TV viewing screen, such as a half-screen display mode or a screen unused mode.

  The main control unit 20 executes the call function at the upper level to shift the mobile phone 1 to the incoming call state, and notifies the user of the incoming call by voice or vibration (S115). At this time, the application manager 31 transmits a signal for instructing the activation of the calling function to the calling application 33 (S314), and the calling application 33 that has received the signal activates the calling function.

  Next, the main control unit 20 determines whether or not the incoming call state is terminated (S117). At this time, the main control unit 20 determines that the incoming call state has been ended when the incoming call is canceled from the called party or when the call processing in the mobile phone 1 is ended. When the incoming state is not finished (No in S117), the main control unit 20 waits until the incoming state is finished. Note that in S117, instead of determining whether or not the incoming call state has ended, it may be determined that “the incoming call state or the subsequent call state has been ended?”. That is, it may be determined whether the incoming state is terminated without the user answering the call, or whether the user is answered and the call is started and the call is ended.

  When the incoming state (or call state) is terminated (Yes in S117), the main control unit 20 terminates the call function (S119). At this time, when the call function is terminated, the call application 33 transmits a signal indicating that the call function is terminated to the application manager 31 (S315). The application manager 31 that has received the signal transmits a signal for requesting the one-seg application 32 to resume the television viewing function (S316).

  The main control unit 20 restores the setting of the television viewing function based on the setting information stored in step S109 (S121). At this time, the one-segment application 32 transmits a signal for requesting the one-seg middleware 36 to set the TV viewing function based on the information stored in step S109 (S308) (S317). The one-segment middleware 36 that has received the signal restores the setting of the TV viewing function based on the received setting information (S318). At this time, the main control unit 20 sets the volume, subtitle display, and display layout before the incoming voice call occurs in step S101 for the television viewing function. Then, the main control unit 20 executes the television viewing function at the upper level (S123).

  When the headset is not used when an incoming voice call occurs (No in S103), or when the program being viewed with the TV viewing function does not have subtitle information (No in S105), the main control is performed. The unit 20 cannot execute the TV viewing function and the call function at the same time, and therefore executes the TV recording function at the lower level (S201). At this time, the one-segment middleware 36 starts recording of the program being watched (time shift recording) (S401).

  The main control unit 20 stores the TV viewing function setting information in the storage unit 23 (S203). At this time, the main control unit 20 stores volume information as setting information. In addition, the one-seg middleware 36 transmits a signal indicating that time-shift recording has started to the one-seg application 32 (S402), and the one-seg application 32 that has received this signal stores the setting information in the storage unit 34 ( S403). The stored setting information is volume information or the like. The stored setting information is used to reset the television viewing function when the call process is terminated.

  The main control unit 20 sets the volume of the TV viewing function to mute (S205). At this time, the one-segment middleware 36 disables the sound by setting the volume of the TV viewing function to mute (S404). Then, the one-segment middleware 36 returns a signal indicating that the voice has been invalidated to the call middleware 37 (S405).

  Then, the main control unit 20 interrupts the TV viewing function (S207). At this time, the call middleware 37 transmits a signal for requesting an interrupt activation (“normal mode”) of the call application to the application manager 31 (S406). The application manager 31 that has received the signal transmits a signal for instructing the television viewing function to be interrupted to the one-segment application 32 (S407), and the one-segment application 32 interrupts the television viewing function (executed at a lower level). ) And a signal indicating the interruption is transmitted to the application manager 31 (S408).

  Then, the main control unit 20 executes the call function at the upper level to shift the mobile phone 1 to the incoming call state, and notifies the user of the incoming call by voice or vibration (S209). At this time, the application manager 31 transmits a signal for instructing activation of the call function to the call application 33 (S409), and the call application 33 that has received the signal activates the call function. At this time, the main control unit 20 executes the call function at the highest level.

  The main control unit 20 determines whether or not the incoming call state is terminated (S211). At this time, the main control unit 20 determines that the incoming call state has been ended when the incoming call is canceled from the called party or when the call processing in the mobile phone 1 is ended. When the incoming state is not finished (No in S211), the main control unit 20 waits until the incoming state is finished. In step S211, as in S117, instead of determining whether or not the incoming call state is ended, a determination may be made “whether the incoming call state or the subsequent call state is ended?”. That is, it may be determined whether the incoming state is terminated without the user answering the call, or whether the user answers the call and enters the call and the call is ended.

  When the incoming (or call) state is ended (Yes in S211), the main control unit 20 ends the call function (S213). At this time, when the call function is terminated, the call application 33 transmits a signal indicating that the call function is terminated to the application manager 31 (S410). The application manager 31 that has received the signal transmits a signal for requesting the one-segment application 32 to start time-shift recording and playback (S411).

  The main control unit 20 restores the setting of the television viewing function based on the setting information stored in step S201 (S215). At this time, the one-segment application 32 transmits a signal for requesting the television viewing function setting to the one-segment middleware 36 based on the information stored in step S203 (S403) (S412). The one-segment middleware 36 that has received the signal restores the setting of the TV viewing function based on the received setting information (S413). At this time, the main control unit 20 sets the volume before the incoming voice call is generated in step S101 for the television viewing function.

  Then, the main control unit 20 executes the television recording / playback function at the upper level (S217). At this time, the main control unit 20 performs time shift recording in which recording processing and playback processing are performed simultaneously. At this time, the one-segment middleware 36 plays the television program recorded in step S201 from the top while continuing the recording process started in step S201 (S401) (S414).

  In this way, the mobile phone 1 sets the TV broadcast sound to silent and displays subtitles when the user uses a headset when a voice call occurs while watching TV. , Transition to incoming state. When the incoming call state ends, the mobile phone 1 returns the voice and subtitle settings to the state before the incoming call. Thereby, the user can continue watching TV on the mobile phone 1 without being disturbed by the voice of the call.

  In addition, when an incoming voice call occurs while watching the TV, the mobile phone 1 is in a case where the TV broadcast being viewed does not include subtitle information, or when the user does not use the headset, Transition to the incoming state after starting the recording of the TV broadcast. Then, when the incoming call state ends, the mobile phone 1 continues recording while playing back the recorded television program.
