Next, the operation concept of the mobile phone device in this embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. That is, in addition to the recording medium, an operation specific to this embodiment can be executed using a program / data supplied externally via a transmission medium. 3 and 4 are flowcharts showing an outline of the operation of the characteristic part of the present embodiment in the entire operation of the mobile phone device. When the flow of FIG. 3 and FIG. Return to the main flow of operation (not shown).

FIG. 3 and FIG. 4 are flowcharts showing an operation to be started when an external speaker device 3 such as a headphone or an earphone is connected to the external speaker connection unit 22.
First, the CPU 11 determines whether the sound is being output, that is, whether the sound output function (music playback function, TV sound output function, etc.) is in operation (step S1 in FIG. 3). After YES in step S1, the audio output to the internal speaker 21 is switched to the audio output to the external speaker device 3 (step S9), and then the flow of FIGS. 3 and 4 is exited. If the audio is not being output (the audio output function is in operation) (NO in step S1), the short-range wireless communication unit 23 is activated to search for the TV broadcast receiving device 2 in the vicinity of the outside (step S2). In this case, after a channel confirmation request (search request) is transmitted from the short-range wireless communication unit 23, a response from the television broadcast receiving apparatus 2 to the channel confirmation request (search request) is waited (step S3).

Here, when receiving the channel confirmation request (search request) from the mobile phone device 1 on the TV broadcast receiving device 2 side, the channel information currently being received is transmitted in response thereto, but it is separated from the mobile phone device 1. If it is out of the communicable area, the channel confirmation request (search request) cannot be normally received and the response (channel information) is not transmitted. It is possible to search for the TV broadcast receiving device 2 in the vicinity of the outside by checking whether the TV broadcast receiving device 2 exists in the vicinity based on the presence or absence of the response.

If there is no response from the television broadcast receiver 2 and there is no television broadcast receiver 2 nearby (NO in step S3), various applications related to audio output (music playback function, TV audio output function, etc.) ) Is checked in advance (step S4), and if the default voice-related application is set (YES in step S4), the voice-related application is activated. (Step S5), switching to the external speaker device 3 as the audio output destination of the application (Step S9). As a result, the flow of FIGS. 3 and 4 ends.

If no default voice-related application is set (YES in step S4), an arbitrary application (function) is selected from various voice-related applications (music playback function, TV voice output function, etc.). A function menu is displayed (step S6). It is checked whether a menu selection operation for selecting an arbitrary menu from the menu screen has been performed (step S7). If the menu selection operation has not been performed (NO in step S7), the flow of FIG. 3 and FIG. 4 ends. However, when a menu selection operation is performed (YES in step S7), the voice-related application of the selected menu is activated (step S8), and then switched to the external speaker device 3 as the voice output destination of the application (step S8). Step S9).

On the other hand, if there is a response from the nearby television broadcast receiving device 2 (YES in step S3), the flow proceeds to the flow of FIG. 4 to receive the channel information from the television broadcast receiving device 2 (step S10) and the television broadcast receiving function. (TV application) is activated (step S11). Then, it is checked whether the broadcast channel indicated by the channel information from the television broadcast receiving device 2 can be received by the television application, for example, whether it is a 1-segment broadcast and the same program can be received (step S12). If so (NO in step S12), the TV application is turned off to terminate the activated TV broadcast receiving function (step S30), and then the process proceeds to step S4 in FIG.

If reception is possible (YES in step S12), a confirmation message for inquiring whether or not to receive the same channel as the channel being received by the television broadcast receiver 2 is displayed (step S13). FIG. 5A shows an example of a confirmation message screen in this case. The confirmation message screen inquires whether the channel being received by the television broadcast receiving device 2 is also received by the mobile phone device 1 side. A message to the effect is displayed, and a “YES” button and a “NO” button for inputting an answer to the inquiry are arranged.

Here, when the “NO” button for rejecting reception is operated (NO in step S14), the TV application is turned off to terminate the activated TV broadcast reception function (step S30), and then the step of FIG. Move on to S4. When the “YES” button for affirming reception is operated (YES in step S14), the output to the display unit 19 (monitor output) is turned off (step S15), and then the channel information from the television broadcast receiving device 2 is displayed. Is instructed to the TV application to receive the broadcast channel indicated by (step S16), and the output destination of the TV sound of the broadcast is switched to the external speaker device 3 to output the sound from the external speaker device 3 (step S17). ).

As a result, the user can listen to the television sound through the external speaker device 3 while viewing the large screen of the television broadcast receiving device 2. In this state, it is checked whether or not a predetermined time (for example, 3 seconds) has elapsed since the above channel confirmation request was transmitted (step S18). That is, whether or not a predetermined time has passed is checked in order to periodically transmit the above-mentioned channel confirmation request to the searched television broadcast receiving apparatus 2 thereafter. Here, when the passage of the predetermined time is detected (YES in step S18), the above-mentioned channel confirmation request is transmitted again (step S19), and then a response waiting state from the television broadcast receiving apparatus 2 is entered (step S20). If there is no response from the television broadcast receiving apparatus 2 (NO in step S20), the power supply on the television broadcast receiving apparatus 2 side is turned off or the user who owns the mobile phone device 1 leaves the television broadcast receiving apparatus 2 Since this is the case, the process moves to the next step S26, and a confirmation message for inquiring whether to continue viewing the current channel broadcast is displayed.

FIG. 5B illustrates a confirmation message screen in this case, and a message for inquiring whether or not to continue watching the broadcast of the channel that has been viewed up to now is displayed on the confirmation message screen. In addition, a “YES” button and a “NO” button for inputting an answer to the inquiry are arranged. Here, when the “NO” button for rejecting continuous viewing is operated (NO in step S27), the TV application is turned off to terminate the activated TV broadcast receiving function (step S29), and then FIG. Although the flow of FIG. 4 is exited, when the “YES” button for affirming continuous viewing is operated (YES in step S27), the output to the display unit 19 (monitor output) is turned on (step S28), and then The process returns to step S18.

If there is a response from the television broadcast receiving apparatus 2 to the re-transmission of the channel confirmation request (YES in step S20), it is checked whether the monitor output is turned on (step S21), and the monitor output is turned on. If this is the case (YES in step S21), the monitor output is turned off (step S22). Then, channel information is received from the television broadcast receiver 2 (step S23), and it is checked whether the channel has been changed on the television broadcast receiver 2 side by comparing the channel information received last time with the channel information received this time (step S23). Step S24).

If the channel has not been changed (NO in step S24), the process returns to the above-described step S18 as it is, but if the channel has been changed on the television broadcast receiving apparatus 2 side (YES in step S24), the current reception is performed. After the broadcast channel indicated by the channel information is received by the television application, the channel on the mobile phone device 1 side is changed (step S25), and the process returns to the above-described step S18. Hereinafter, every time a predetermined time has elapsed since the channel confirmation request is transmitted, the above operation is repeated while the channel confirmation request is transmitted again.
