  The control unit 10 controls the operation of each unit described above according to a predetermined program. In particular, according to the first embodiment, in addition to normal outgoing / incoming processing, call processing, TV broadcast reception processing by a TV application, processing for converting subtitle information of TV broadcast into synthesized sound, and switching according to terminal opening / closing Switching between normal audio and subtitle reading, switching of audio output according to the genre of the program being viewed, and the like are performed. The power supply unit 11 is composed of a rechargeable secondary battery, and supplies power for operation to the above-described units.

  Next, FIG. 2 is a conceptual diagram for explaining the states and meanings of the voice switching flag and the switching genre flag stored in the storage unit 5. When the audio switching flag is set to “0”, it indicates that normal audio is not switched to caption reading when the mobile phone is closed while watching a TV program (normal voice / caption reading switching disabled) ), When set to “1”, indicates that normal voice is switched to caption reading when the mobile phone is closed (normal voice / caption reading switching enabled). The voice switching flag is set to “1” by default, but can be changed as appropriate by the user (details will be described later).

  The switching genre flag is set for each program genre, details of which will be described later. When it is set to “0”, it indicates that the genre does not switch normal audio to caption reading (switching invalid genre). ), When “1” is set, it indicates that the genre is to switch normal voice to caption reading (switchable genre).

  FIG. 3 is a conceptual diagram showing a state of the switching genre table 5-1 in which the above-described switching genre flag is stored. As shown in FIG. 3, the switching genre table 5-1 is set with a switching genre flag indicating whether or not normal audio output is switched to subtitle-reading audio (synthesized audio) for each program genre. In the illustrated example, the switching genre flag is set to “0: invalid” for movies, music, and variety, and the switching genre flag is set to “1: valid” for drama, sports, news, culture, and others. Is set. Although the state shown in FIG. 3 is the default, it can be changed as appropriate by the user (details will be described later).

  FIG. 4 is a schematic diagram illustrating an example of an operation state when the mobile phone is opened. When the mobile phone is open, the video is displayed on the main display unit 6, the sound is output from the earphone attached to the earphone jack 8-2, and the subtitle is turned off.

  FIG. 5 is a schematic diagram illustrating an example of an operation state when the mobile phone is closed. When the mobile phone is closed, the video and normal sound are turned off, and the subtitle-reading sound is output from the earphone attached to the earphone jack 8-2.

A-2. Operation of First Embodiment Next, the operation of the first embodiment described above will be described. Here, FIG. 6 and FIG. 7 are flowcharts for explaining the operation (main routine) of the mobile phone according to the first embodiment. First, it is determined whether or not the power is turned on (step S10). When the power is turned on, a startup process such as initialization of parameters necessary for the operation is performed (step S12). Next, a standby screen is displayed (step S14), and it is determined whether or not a television application activation operation has been performed (step S16).

  If there is no operation for starting the TV application, it is determined whether or not there is a setting operation (step S18). If there is a setting operation, various parameter setting processing is executed (step S20). Return to S14. Details of the setting process will be described later. On the other hand, if there is no setting operation, it is determined whether or not there is another operation (step S22). If there is another operation, processing corresponding to the other operation is executed (step S24). Return to step S14.

  On the other hand, when a TV application activation operation is performed, first, the currently received program genre is acquired (step S26), and the video is output to the main display unit 6 (step S28). Next, it is determined whether or not the earphone is attached to the earphone jack 8-2 (step S30). If the earphone is attached, normal sound is output from the earphone (step S32). Next, it is determined whether or not the mobile phone is closed (step S34). If the mobile phone is closed, a terminal closing process is executed (step S36). The details of the terminal closing process will be described later. To briefly explain here, both the audio switching flag and the switching genre flag are valid, and the audio output of the earphone is read out as a subtitle (synthesized audio) only when there is a subtitle. ).

  Next, it is determined whether or not the mobile phone has been opened (step S44), and this state is maintained until the mobile phone is opened. On the other hand, when the mobile phone is opened, the process returns to step S28, and the video is output to the main display unit 6 again, and the normal sound is output from the earphone attached to the earphone jack 8-2 to continue viewing.

  On the other hand, if it is determined in step S30 that the earphone is not worn, normal sound is output from the speaker 8-1 (step S38). Then, it is determined whether or not the mobile phone has been closed (step S40). If the mobile phone has been closed, the television application is paused without switching to subtitle reading (step S42).

  Next, it is determined whether or not the mobile phone has been opened (step S44), and the television application is suspended until the mobile phone is opened. On the other hand, when the mobile phone is opened, the process returns to step S28, and the video is output to the main display unit 6 again, and normal audio is output from the speaker 8-1 to resume viewing.

  If the mobile phone is not closed while watching the TV program described above (NO in step S34, NO in step S40), it is determined whether a program switching operation has been performed (step S46). If there is a program switching operation, the received program is changed (step S48), and the process returns to step S26 to continue viewing the changed program.

  On the other hand, if there is no program switching operation, it is determined whether or not a television application termination operation has been performed (step S50). If there is a TV application end operation, TV application end processing is executed (step S52), and the screen returns to the standby screen in step S14.

  If there is no TV application end operation, it is determined whether or not there is another operation (volume adjustment or the like) (step S54). If there is another operation, the other TV application operation processing is executed (step S56), and the process returns to step S30 to continue watching the TV program.

  Next, FIG. 8 is a flowchart for explaining the operation of the terminal closing process described above. In the terminal closing process, when the mobile phone is closed while watching the TV program, the video output is stopped (step S60), and it is determined whether or not the audio switching flag is “1” (step S62). When the voice switching flag is not “1”, that is, when the voice switching flag is set to “0” normal voice / caption reading switching disabled as shown in FIG. The terminal closing process is terminated without switching, and the process returns to the main routine described above.

  On the other hand, when the voice switching flag is “1”, that is, when the voice switching flag is set to enable normal voice / caption reading switching of “1” as shown in FIG. −1, it is determined whether or not the switching genre flag corresponding to the program genre acquired in step S26 is “1” (step S64). When the switching genre flag is not “1”, that is, when the switching genre flag is set to the switching invalid genre of “0”, the terminal closing process is terminated without switching the audio output to the caption reading. Then, the process returns to the main routine described above.

  Thus, when either the audio switching flag or the switching genre flag is set to “0”, the audio output is not switched to caption reading even when the terminal is closed during viewing of the television program.

  If both the audio switching flag and the switching genre flag are set to “1”, it is determined whether or not there is a caption in the currently viewed broadcast data (step S66). If there is no caption, the terminal closing process is terminated without switching the audio output to caption reading, and the process returns to the main routine described above.

  On the other hand, if both the audio switching flag and the switching genre flag are set to “1” and there is a caption in the broadcast data, the caption is decoded (step S68). Subtitle audio processing for converting subtitles (character codes) into synthesized speech is executed (step S70), and the audio output of the earphone is switched to subtitle reading that reads out the subtitles with the synthesized speech (step S72). Thereafter, the process returns to the main routine.

  Next, FIG. 9 is a flowchart for explaining the operation of the setting process described above. When a setting operation is performed by the operation unit 3 on the standby screen, it is first determined whether or not it is a voice switching setting operation (step S80). If it is a voice switching setting operation, a voice switching is performed. It is determined whether or not the flag is “1” (step S82). If the voice switching flag is “1”, that is, if normal voice / caption reading switching is valid, the voice switching flag is set to “0”, that is, Then, the normal voice / caption reading switching is disabled (step S84). Thereafter, the process returns to the main routine.

  On the other hand, when the voice switching flag is not “1”, that is, when the normal voice / caption reading switching is disabled, the voice switching flag is set to “1”, that is, the normal voice / subtitle reading switching is enabled (step) S86). Thereafter, the process returns to the main routine.

  If it is not a voice switching setting operation, it is determined whether or not it is a switching genre setting operation (step S88). If it is a switching genre setting operation, a program genre to be set is selected (step S90). ). The program genre is selected by selecting a genre desired by the user from the list of program genres displayed on the main display unit 6 by operating the operation unit 3 (cursor keys or the like).

  Next, when the program genre is selected, the switching genre flag table 5-1 shown in FIG. 3 is referred to, and it is determined whether or not the switching genre flag of the selected program genre is “1” (step S92). ) If the switching genre flag is “1”, that is, the switching valid genre, the switching genre flag is set to “0”, that is, the switching invalid genre (step S94). Thereafter, the process returns to the main routine.

  On the other hand, when the switching genre flag of the selected program genre is “0”, that is, the switching invalid genre, the switching genre flag is set to “1”, that is, the switching valid genre (step S96). Thereafter, the process returns to the main routine.

  If the setting operation is neither a voice switching setting operation nor a switching genre setting operation, it is determined whether or not the setting operation is another setting operation (step S98). Is executed (step S100), and then the process returns to the main routine. On the other hand, if there is no other setting process, the process directly returns to the main routine.

  According to the first embodiment described above, when the terminal is closed while watching a TV program, the audio output is switched from normal audio to subtitle-reading audio (audio synthesis), so that the cellular phone is closed and the video is viewed. Even if it is not possible, it is possible to keep track of the broadcast content.

  In addition, during subtitle reading, only subtitle decoding is performed, and video and audio decoding and display on the main display unit 6 are stopped, so that power consumption can be reduced while continuously grasping the broadcast content. .

  In addition, since the voice output is switched from the normal sound to the caption reading sound according to the genre of the program being viewed, it is possible to automatically switch only the program suitable for caption reading.

  In addition, since it is possible to set whether to output the normal audio output as subtitle-reading sound (speech synthesis) for each program genre, it is possible to switch to subtitle-reading more flexibly and improve user convenience. be able to.

B. Second Embodiment Next, a second embodiment of the present invention will be described. In the second embodiment, when the mobile phone is closed while watching a TV program, depending on the program and contents, normal audio output may be easier to understand than subtitle reading. Switching between normal audio output is possible. The configuration of the mobile phone is the same as that shown in FIG.

Next, the operation of the above-described second embodiment will be described.
FIG. 10 is a flowchart for explaining the operation of the mobile phone according to the second embodiment. First, it is determined whether or not the power is turned on (step S110). When the power is turned on, a startup process such as initialization of parameters necessary for the operation is performed (step S112). Next, a standby screen is displayed (step S114), and it is determined whether or not a TV application activation operation has been performed (step S116).

  If there is no operation for starting the TV application, it is determined whether or not there is any other operation (step S118). If there is another operation, processing corresponding to the other operation is executed (step S118). S120), the screen returns to the standby screen in step S114.

  On the other hand, when a TV application activation operation is performed, first, the currently received program video is output to the main display unit 6 and communication audio is output to the earphone inserted in the earphone jack 8-2 ( Step S122). Next, it is determined whether or not the mobile phone has been closed (step S124). If the mobile phone has been closed, it is determined whether or not the user has performed an audio output switching operation (step S126).

  If there is an audio output switching operation, it is determined whether or not the audio output is normal audio (step S128). If the audio output is normal audio, the currently viewed broadcast data It is determined whether or not there is a caption (step S130). And when there is no caption, it returns to step S126 mentioned above, without switching audio | voice output.

  On the other hand, when there is a caption in the broadcast data, the caption is decoded (step S132), caption audio processing for converting the decoded caption (character code) into synthesized speech is executed (step S134), and audio output is performed. Is switched to reading out subtitles by reading out the subtitles in the synthesized speech (step S136).

  If the audio output is not normal audio when the audio output switching operation is performed, that is, if the subtitle is read out to read out the subtitle, the audio output is switched to normal audio (step S138).

  In any case, after switching the voice output, it is determined whether or not the mobile phone is opened (step S148). If the mobile phone is not opened, the process returns to step S126 to continue the current voice output. If the mobile phone is opened, the process returns to step S122 to output the currently received program video to the main display unit 6 and to insert the communication audio into the earphone jack 8-2. Output to the existing earphone and continue watching.

  If the mobile phone is not closed while watching a TV program (NO in step S124), or if there is no audio output switching operation (NO in step S126), whether or not a TV application end operation has been performed. Is determined (step S140). If there is a TV application end operation, a TV application end process for ending the TV application is executed (step S142), and the screen returns to the standby screen in step S114.

  On the other hand, if there is no TV application end operation, it is determined whether or not there is another operation (volume adjustment or the like) (step S144). If there is another operation, the other TV application operation processing is executed (step S146), and the process returns to step S120 to continue watching the TV program.

  According to the second embodiment described above, when the terminal is closed while watching a TV program, it is possible to switch between subtitle reading and normal audio output by a user operation. The user can select between reading out and normal audio output, and it is possible to respond more flexibly according to the user's situation and the genre of the program.

  In the above-described embodiment, only the folding-type mobile phone has been described. However, the present invention is not limited to this and can be applied to all types of mobile phones. In the case of the folding type, voice output can be automatically switched by mechanically and magnetically detecting the opening and closing of the mobile phone. On the other hand, in the case of a mobile phone other than the folding type, there is no operation of “opening / closing” the mobile phone in the first place.
