(First embodiment)
FIG. 1 is a block diagram showing a main configuration of a mobile communication terminal as a broadcast receiving apparatus according to the first embodiment of the present invention.

  This mobile communication terminal is equipped with a TV application for viewing so-called 1-segment broadcasting, which is a terrestrial digital TV broadcast, as the first application, and the RF of the digital TV signal received by the antenna 1 while the TV application is activated. The signal is tuned by the tuner unit 2 based on a frequency (channel) designation command from the control unit 11 and frequency-converted into a channel signal, and then demodulated into an MPEG transport stream (TS) signal by the demodulation unit 3. Further, the decoding unit 4 decodes the audio packet and the video packet based on the packet ID in the TS signal.

  The audio packet decoded by the decoding unit 4 is supplied to the audio control unit 5, audio data is output from the speaker 6, and the video packet is supplied to the screen control unit 7 so that the video data is output to the display 8. It has become.

  In addition to voice calls, communication mail can be created as a second application that requires character input. These voice call signals and mail data communication signals are transmitted and received by the antenna 9, and the control unit The signal is modulated / demodulated by the telephone transmitting / receiving unit 10 under the control of 11.

  During the activation of the second application, that is, during the creation of the mail, a signal generated by the operation of the key unit 13 is supplied to the character conversion unit 14, where the data in the dictionary unit 16 is used as necessary to convert it into kanji. Characters that have been converted and become conversion candidates are output to the display 8 via the screen control unit 7.

  In the present embodiment, the TV application is operated in the background so that the mail creation application can be executed while listening to the sound of the TV broadcast of the desired channel from the speaker 6 or the earphone (not shown). In the middle, operation characters related to TV applications such as TV station tuning and volume adjustment are displayed on the display 8 together with conversion candidates in accordance with character input so that the corresponding operation can be executed when the operation character is selected. To do.

  Therefore, in the present embodiment, the operation character control unit 12, the operation character addition unit 15, and the operation character dictionary unit 17 are provided, and during the “listening while” operation character addition unit 15 operates the operation character according to the character input. Is acquired using the data of the operation character dictionary unit 17, and the acquired operation character is added to the conversion candidate character converted by the character conversion unit 14 and supplied to the screen control unit 7 for display together with the conversion candidate character. 8 is displayed. That is, it has an operation character adding unit 15, an operation character dictionary unit 17, and a screen control unit 7, and constitutes a display control means for selectively displaying conversion candidate characters and operation characters on the display 8.

  In addition, when an operation character is selected on the display 8 by configuring the operation control means having the operation character control unit 12, an operation corresponding to the operation character is made to the TV application operating in the background. Notify and execute.

  Even if an operation character is selected, it is not input as a character to the mail creation application being executed. While only the mail creation application that does not “listen while” is being executed, only the conversion candidate characters converted by the character conversion unit 14 are displayed via the screen control unit 7 without adding the operation characters in the operation character addition unit 15. 8 is displayed.

  FIG. 2 shows a screen display example of the display 8 when the mail text is created during “listening while”.

  In the present embodiment, during the creation of the mail text, the pictogram display unit 22, the input display unit 23, the conversion candidate display unit 24, and the soft key display unit 25 are set from the top to the bottom of the screen to display the pictograph. The battery mark indicating the remaining battery level, the antenna mark indicating the electric field strength of the received signal in the communication line, the current time, etc. are displayed on the unit 22, and the characters already determined to be converted are displayed on the input display unit 23 and input before the determination Characters are displayed, conversion candidate display portion 24 displays input character conversion candidates and operation characters during “listening while listening”, and soft key display portion 25 has functions of predetermined keys provided in key portion 13. A soft key indicating the assignment of the key is displayed.

  The conversion candidates and operation characters displayed on the conversion candidate display unit 24 are selected by the operation of a four-way key such as a cross key provided on the key unit 13 and are displayed on the “OK” key of the soft key display unit 25. It is determined by operating the corresponding determination key. After the operation of the enter key, the conversion candidate display unit 24 is set to be erased and become an area of the input display unit 23 until a new character is input from the key unit 13.

  Hereinafter, an operation of creating a mail by “listening while listening” according to the present embodiment will be described with reference to a flowchart shown in FIG.

  First, it is determined whether a character is being input, that is, whether a mail is being created (step S1), and if a mail is being created, the key conversion unit 14 waits for the key to be pressed (step S2). It is determined whether or not the pressed key is a decision key (step S3). Here, if the pressed key is other than the enter key, it is converted into a corresponding character, and a conversion candidate is obtained based on the character data and the data in the dictionary unit 16 (step S4). This is a normal character input operation.

  Thereafter, the control unit 11 determines whether or not listening is being performed (step S5). If the listening is being performed, an operation character corresponding to the character input is added to the conversion candidate by the operation character adding unit 15 ( In step S6), the screen control unit 7 displays the conversion candidate on the conversion candidate display unit 24 of the display 8, for example, as shown in FIG.

  On the other hand, if it is determined in step S5 that it is not listening, only conversion candidates are displayed on the display 8 as shown in FIG. 4 in step S7 without adding operation characters in step S6. The information is displayed on the unit 24 and the process returns to step S1.

  On the other hand, if the pressed key is the enter key in step S3, it is determined whether or not the next selected character is an operation character (step S8).

  Here, when the selected character is an operation character, the operation character control unit 12 identifies the operation of the operation character, notifies the application operating in the background, and executes the operation character operation ( Step S9), the process returns to step S1. In the execution of the operation character operation in step S9, the display 8 remains in the character input screen, the background application is not displayed on the front, and the operation character is not added to the input display unit 23.

  On the other hand, if the selected character is not an operation character, the selected character is added to the input display unit 23 of the display 8 (step S10), and the process returns to step S1.

  The above operation is repeated until it is determined in step S1 that characters are being input, that is, until the mail creation application is terminated.

  In FIG. 2, when the character “A” is input, “UP tuning” that is an operation character starting from “A” is added from the operation character dictionary 17 together with the TV application icon to the top of the conversion candidate The case where it displays is shown. Here, in FIG. 2, the focus is on “up channel selection” as an operation character, but this focus is performed by blinking the operation character or changing the character color or background color to display it. You can also. Further, when displaying conversion candidates so as not to hinder character input, the initial position may be focused on characters other than the operation characters as shown in FIG.

  Further, the operation character is not limited to being displayed at the top of the conversion candidate, but can be additionally displayed at the end of the conversion candidate displayed on the conversion candidate display unit 24 as shown in FIG. In this way, if it is not initially displayed on the conversion candidate display unit 24, the operation character is displayed by moving to the previous (final) page, so that the operation character can be easily selected without interfering with character input. can do.

  Furthermore, the operation character can be additionally displayed at the last position on the screen of the conversion candidate display unit 24 as shown in FIG. In this way, since the operation character is displayed last even if the conversion candidate moves to the next page, it is possible to easily select the operation character without hindering character input as in the above case.

  In addition to “up channel selection”, the operation characters include “down channel selection”, “volume up”, “volume down”, and the like. For example, when the character “DA” is input The operation character of “down tuning” is additionally displayed, and when the characters “o” and “bo” are entered, the operation characters of “volume up” and “volume down” are additionally displayed, and the desired operation characters Should be selected. As for channel selection, for example, when a character “se” is input, operation characters “up channel selection” and “down channel selection” are additionally displayed so that a desired operation character can be selected. Good.

  Further, the additional display of the operation character is not limited to the one having the first character that matches the input character. During “listening while”, for example, as shown in FIG. A plurality of operation characters may be displayed to select a desired operation character.

  As described above, in the present embodiment, during “while watching”, the operation characters related to the TV application operating in the background according to the character input are added to the input character conversion candidates and displayed, and the operation characters are displayed. When is selected, the TV application operation corresponding to the operation character is executed, so the mail creation application being executed is interrupted with a simple and inexpensive configuration sharing the display 8 and the key unit 13. It is possible to easily carry out a desired operation such as channel change or volume change related to the TV application without performing the operation.

(Second Embodiment)
FIG. 9 is a diagram for explaining a second embodiment of the present invention, and shows a screen display example on the display 8 of FIG.

  In this embodiment, during “listening while listening”, information related to TV broadcasting such as the name of a service or program currently being listened to in the background is acquired from an electronic program guide (EPG) or the like in the decoding unit 4. These are additionally displayed on the conversion candidate display unit 24 of the display 8 together with the conversion candidates according to the character input. Therefore, in the case of the present embodiment, in FIG. 1, the operation character control unit 12, the operation character addition unit 15, and the operation character dictionary unit 17 are omitted, and the decoding unit 4, the screen display unit 7, and the control unit 11 are provided. Thus, the display control means of the display 8 is configured.

  In FIG. 9, each time a character is input, the program name “9 o'clock news” is additionally displayed together with the TV application icon. For example, it is the first character of the program name. When the character “B” is input, the program name may be displayed together with the conversion candidate. Further, information related to TV broadcasting such as the program name can be added to the input display unit 23 of the display 8 as selectable.

  According to the present embodiment, it is possible to easily recognize the name of the program that is currently being listened to without interrupting the mail creation application being executed and starting the TV application during “listening while”. Therefore, it can contribute to service improvement.
