Move position. When the user turns on the determination switch, the determination result in step SA23 is “YES”, and the flow proceeds to step SA25. When the clear switch is turned on to cancel the selection / execution instruction of the processing item related to the mail function, the determination result in step SA24 is “YES”, and the process proceeds to step SA2 shown in FIG. Return to the standby screen display state.

Next, in steps SA25 to SA24, the processing item selected / executed in steps SA14 to SA16 is activated. In other words, if the processing item selected / executed by turning on the cursor switch and the decision switch is “create new”, the determination result in step SA25 is “YES”, and the process proceeds to step SA26 to create a new mail. After executing the new creation process, the process returns to step SA19 to return to the mail screen display state.
If the selected / executed processing item is “Receive BOX”, the determination result in Step SA27 is “YES”, the process proceeds to Step SA28, and the received mail stored in the received BOX in the mail area of the RAM 14 is displayed. After receiving BOX processing such as displaying a list, the mail list screen display state is restored.
If the selected / executed processing item is other than “new creation” and “reception BOX”, the process proceeds to step SA29 to execute other mail processing and then return to the mail list screen display state.

(2) Operation of Incoming Call Detection Process Next, the operation of the incoming call detection process will be described with reference to FIG. If there is an incoming call during the execution of the main routine described above, the control unit 12 interrupts this process and proceeds to step SB1 to display on the display unit 18 an incoming call screen for notifying the user of the incoming call. Subsequently, in steps SB2 to SB3, an incoming call notification is performed until the user turns on the off-hook switch. When the off-hook switch is turned on, the determination result in step SB3 is “YES”, and the process proceeds to step SB4. In step SB4, it is determined whether or not the TV unit 20 is turned on.

If the TV unit 20 is set to ON, the determination result is “YES”, and the flow proceeds to step SB5. In steps SB5 to SB6, the demodulation unit 22 and the decoding unit 23 are instructed to extract and decode the metadata and the audio is muted. In response to this, the metadata output from the decoding unit 23 is displayed on the display unit 18, and then to step SB7. move on. On the other hand, if the TV unit 20 is not set to ON, the determination result in step SB4 is “NO”, and the process proceeds to step SB7.
Next, in steps SB7 to SB9, the call processing in step SB7 is executed following the processing in steps SB4 to SB6 until the user turns on the on-hook switch. In other words, if there is an incoming call when the TV section 20 is set to ON, a call is made after switching from a normal broadcast reception mode that outputs video and audio to a metadata broadcast reception mode that outputs metadata and mutes the audio. Execute the process. Accordingly, the display form of the display unit 18 is changed from the moving image display to the character display to reduce power consumption, and the received sound is muted to enable parallel processing of communication processing and broadcast reception processing. Yes. Then, when the user turns on the on-hook switch, the determination result in step SB8 is “YES”, and the process proceeds to step SB9. Return.

(3) Operation of Mail Arrival Detection Process Next, the operation of the mail arrival detection process will be described with reference to FIG. If there is an incoming mail during the execution of the main routine described above, the control unit 12 interrupts and executes this process, and proceeds to step SC1 shown in FIG.

Subsequently, in steps SC3 to SC4, an incoming mail notification is performed for a predetermined time. If the mail arrival notification is performed for a certain period of time, the determination result in step SC4 becomes “YES”, the process proceeds to step SC5, and the incoming notification is stopped.

  Next, in steps SC6 to SC7, it is determined whether or not the off-hook switch or the clear switch is turned on. When the incoming mail is not opened, the clear switch is turned on. In this case, the determination result in step SC7 is “YES”, and this process is completed. On the other hand, when the off-hook switch is turned on to open the incoming mail, the determination result in step SC6 is “YES”, and the flow proceeds to step SC7. In step SC7, it is determined whether or not the TV unit 20 is turned on. If the TV unit 20 is set to OFF, the determination result is “NO”, the process proceeds to step SC8, the contents of the incoming mail are displayed on the display unit 18, and then the process proceeds to step SC11.

  On the other hand, if the TV section 20 is turned on when opening the incoming mail, the determination result in step SC7 is “YES”, and the flow proceeds to step SC9. In step SC9, the demodulation unit 22 and the decoding unit 23 are instructed to extract and decode metadata, and the metadata output by the decoding unit 23 is displayed in the upper half of the display area in the display unit 18 in response to this. In step SC10, the text of the incoming mail is displayed in the lower half of the display area of the display unit 18. As described above, when the TV unit 20 is set to ON when opening the incoming mail, the normal broadcast reception mode for outputting video / audio is switched to the metadata broadcast reception mode for outputting metadata, and the display unit 18 is switched. The received metadata is displayed on the upper half of the display area and the incoming mail text is displayed on the lower half of the display area so that the received metadata and incoming mail contents can be checked simultaneously.

  Then, when the user turns on the on-hook switch to end the mail display, the determination result in step SC11 is “YES”, and the flow proceeds to step SC12. In step SC12, it is determined whether or not the TV unit 20 is turned on. If the TV unit 20 is set to OFF, the determination result is “NO”, the process returns to step SA2 of the main routine shown in FIG. 2, and returns to the standby screen display state. On the other hand, if the TV unit 20 is set to ON, the determination result is “YES”, the process proceeds to step SC13, the metadata broadcast reception form is changed to the normal broadcast reception form, and then the process returns to the main routine. .

  As described above, in the present embodiment, when there is an incoming call to the mobile phone unit 10 while the TV unit 20 is operating, the control unit 12 changes the TV unit 20 from the normal broadcast receiving mode that outputs video / audio. Since the mobile phone unit 10 performs call processing in a state in which the power consumption of the TV unit 20 is reduced by changing to a metadata broadcast reception mode in which data is output and the sound is muted, communication processing and broadcast reception processing are performed in parallel. Can be processed. As a result, for example, it is possible to receive metadata of professional baseball broadcasts, display the contents of the game in text, and talk with the other party while reading this.

  Further, in the present embodiment, when there is an incoming mail in the mobile phone unit 10 during the operation of the TV unit 20, the control unit 12 outputs the video / sound to the TV unit 20 in response to the user's incoming mail opening operation. The broadcast reception mode is changed to a metadata broadcast reception mode for outputting metadata, and the received content of the metadata broadcast is displayed on the upper half of the display area of the display unit 18 and the text of the incoming mail opened on the lower half is displayed on the screen. Therefore, mail processing and broadcast reception processing can be processed in parallel. As a result, it is possible to confirm the content of the incoming mail while viewing the received content of the metadata broadcast.

  In the above-described embodiment, the case where an incoming call or an incoming mail has occurred in the mobile phone unit 10 during the operation of the TV unit 20 has been described. However, the present invention is not limited to this. If the mobile phone unit 10 activates the Web browser function and connects to the Internet while the TV unit 20 is operating, the metadata broadcast reception is performed so that the TV unit 20 outputs metadata from the normal broadcast reception mode. It can also be set as the aspect changed to a form. In such a case, for example, when a URL of a site is displayed as metadata, the site can be immediately connected with reference to the URL.
