  The background sound determination processing unit 206 refers to the detected background sound information holding unit 201 and includes the background sound set as the detection target in the detected background sound information holding unit 201 in the sound signal extracted by the sound extraction unit 204. It is determined whether or not.

  The keyword sound determination processing unit 207 refers to the detected keyword sound information holding unit 202, and the keyword signal set as the detection target in the detected keyword sound information holding unit 202 is included in the sound signal extracted by the sound extraction unit 204. It is determined whether or not.

  The image determination processing unit 208 refers to the detected image information holding unit 203 and determines whether or not the video signal extracted by the video extracting unit 205 includes a face image set as a detection target in the detected image information holding unit 203. Determine.

  The broadcast notification control unit 209 reads background sounds, keyword sounds, and face images set as detection targets from the detected background sound information holding unit 201, the detected keyword sound information holding unit 202, and the detected image information holding unit 203. The broadcast notification control unit 209 broadcasts broadcast scenes (scenes) to be viewed by the user based on the determination results of the background sound determination processing unit 206, the keyword sound determination processing unit 207, and the image determination processing unit 208. This is notified to the display control unit 210.

  Upon receiving the broadcast notification from the broadcast notification control unit 209, the display control unit 210 displays a message indicating that the broadcast setting (scene) to be viewed is broadcast if the switching setting is manual. If the switching operation is performed via the touch panel 320, the display 310 is switched to the television image.

Next, a broadcast notification process for notifying that a broadcast scene executed by the mobile terminal device 100 having such a function is being broadcast will be described with reference to FIGS. 6 and 7.
FIG.6 and FIG.7 is a flowchart which shows the broadcast notification process performed with the portable terminal device which concerns on 2nd Embodiment.

  In the mobile terminal device 100, before executing the broadcast notification process, based on the operation input from the user to the touch panel 320, as shown in FIG. 5, the detected background sound information holding unit 201 and the detected keyword sound information holding unit 202 are displayed. Arbitrary background sounds, keyword sounds, and face images are registered in the detected image information holding unit 203, respectively. In addition, among the registered items, what is considered to be included in the broadcast scene (scene) to be viewed is set as a detection target (“ON”).

After such an initial setting, the mobile terminal device 100 executes the following process every time the tuner unit 400 receives a broadcast signal via the antenna 400a.
[Step S11] The broadcast notification control unit 209 refers to the detected background sound information holding unit 201, the detected keyword sound information holding unit 202, and the detected image information holding unit 203, and reads the detection setting status of each holding unit.

  For example, in the case of FIG. 5, “cheer” detected and set from the detected background sound information holding unit 201, and “ABC (player name)” from the detected keyword sound information holding unit 202 and the detected image information holding unit 203. And “ABC (player name) face image” are read.

[Step S12] The broadcast notification control unit 209 determines whether or not at least one detection setting has been read in step S11.
In the next process, when at least one detection setting is read, the process of step S13 is executed. When no detection setting is read (no detection setting), the broadcast notification process is terminated. .

  For example, in the case of FIG. 5, “Cheer” is stored in the detected background sound information holding unit 201, and “ABC (player name)” and “ABC (” are stored in the detected keyword sound information holding unit 202 and the detected image information holding unit 203. Since “face image of (player name)” is set, it is determined that there is at least one detected detection setting, and the process of step S13 is executed.

[Step S13] The background sound determination processing unit 206 refers to the detected background sound information holding unit 201 and determines whether or not a detection setting (“ON”) is included.
In the next process, when the detection setting is included, the process of step S14 is executed, and when the detection setting is not included, the process of step S17 is executed.

For example, in the case of FIG. 5, since “cheer” in the detected background sound information holding unit 201 is set as a detection target (including detection setting), the process of step S14 is executed.
[Step S14] The background sound determination processing unit 206 performs background sound analysis from the audio signal of the broadcast signal extracted by the audio extraction unit 204.

[Step S15] The background sound determination processing unit 206 determines whether the background sound analyzed in step S14 includes the background sound detected and set by the detected background sound information holding unit 201.
The next process proceeds to step S25 when the background sound analyzed at step S14 includes the background sound detected and set by the detected background sound information holding unit 201. When the background sound is not included, The process proceeds to step S16.

  [Step S16] The background sound determination processing unit 206 determines whether or not the determination of the background sound analyzed for all the background sounds detected and set in the detected background sound information holding unit 201 is completed.

  In the next process, if all the detected background sounds have not been determined, the process of step S14 is executed again. If the determination has been completed, the process of step S17 is executed. The

[Step S17] The keyword sound determination processing unit 207 refers to the detected keyword sound information holding unit 202 and determines whether or not a detection setting (“ON”) is included.
If the detection setting is included, the process of step S18 is executed. If the detection setting is not included, the process of step S21 is executed.

  For example, in the case of FIG. 5, since “ABC (player name)” in the detected keyword sound information holding unit 202 is set as a detection target (including detection setting), the process of step S18 is executed.

[Step S18] The keyword sound determination processing unit 207 executes an analysis of the keyword sound from the sound signal of the broadcast signal extracted by the sound extraction unit 204.
[Step S19] The keyword sound determination processing unit 207 determines whether or not the keyword sound analyzed in step S18 includes information on the keyword sound detected and set by the detected keyword sound information holding unit 202.

  The next process proceeds to step S25 if the keyword sound analyzed in step S18 includes information about the keyword sound detected and set by the detected keyword sound information holding unit 202. If the keyword sound is not included, Advances to step S20.

  [Step S20] The keyword sound determination processing unit 207 determines whether or not the keyword sound analyzed for all the keyword sounds detected and set in the detected keyword sound information holding unit 202 has been determined.

  In the next process, if the determination of all detected and set keyword sounds has not been completed, the process of step S18 is executed again. If the determination has been completed, the process of step S21 is executed. The

[Step S21] The image determination processing unit 208 refers to the detected image information holding unit 203 and determines whether or not a detection setting (“ON”) is included.
In the next process, when the detection setting is included, the process of step S22 is executed, and when the detection setting is not included, the process of step S25 is executed.

  For example, in the case of FIG. 5, since “ABC (player name) face image” of the detected image information holding unit 203 is set as a detection target (including detection setting), the process of step S <b> 22 is executed. The

[Step S <b> 22] The image determination processing unit 208 analyzes the face image from the image signal of the broadcast signal extracted by the video extraction unit 205.
[Step S23] The image determination processing unit 208 determines whether or not the face image analyzed in step S22 includes information related to the face image detected and set by the detected image information holding unit 203.

  The next process proceeds to step S25 if the face image analyzed in step S22 includes information related to the face image detected and set by the detected image information holding unit 203, and proceeds to step S25 if it is not included. The process proceeds to step S24.

  [Step S <b> 24] The image determination processing unit 208 determines whether or not the detection image information holding unit 203 has determined that all face images detected and set have been analyzed.

  In the next process, if the determination of all detected face images has not been completed, the process of step S22 is executed again. If the determination has been completed, the broadcast notification process is terminated. .

  [Step S <b> 25] The broadcast notification control unit 209 notifies (display control unit 210) that a broadcast scene (scene) to be viewed by the user is broadcast on the display 310.

Thus, the broadcast notification process ends.
Next, in the mobile terminal device 100, while an application is being executed, the broadcast scene is broadcast on the display 310 due to the occurrence of a notification event indicating that the broadcast scene to be viewed is being broadcast. TV video display switching processing for switching to TV video will be described with reference to FIG.

FIG. 8 is a flowchart showing a television video display switching process executed by the mobile terminal device according to the second embodiment.
[Step S31] The control unit 200 of the mobile terminal device 100 waits for an event to occur.

The event includes, for example, reception / transmission / creation of mail, activation of a browser, activation of other applications, and the like.
[Step S32] The control unit 200 of the mobile terminal device 100 determines whether or not an event has occurred in step S31.

If no event has occurred, the process proceeds to step S31. If an event has occurred, the process of step S33 is executed.
[Step S <b> 33] The control unit 200 of the mobile terminal device 100 determines whether or not the event determined to be generated in step S <b> 32 is a broadcast notification event generated in the processes of FIGS. 6 and 7.

If it is not a broadcast notification event, the process of step S34 is executed, and if it is a broadcast notification event, the process of step S35 is executed.
[Step S34] The control unit 200 of the mobile terminal device 100 executes the event determined in step S32.

  [Step S35] When the broadcast notification control unit 209 notifies that the broadcast scene is being broadcast from the broadcast notification control unit 209 (step S25 (FIG. 7)), the display control unit 210 switches the display 310 display to the TV video. Determine whether the setting is automatic or manual.

  The next process proceeds to the process of step S36 if the means for switching to the television image is set manually, and proceeds to the process of step S38 if it is automatically set.

Note that the automatic or manual setting of the means for switching to the television image is performed by a user's operation input to the touch panel 320 in advance.
[Step S <b> 36] The display control unit 210 causes the display 310 to display that the broadcast scene to be viewed is being broadcast, and displays a switch button for switching to a television image that broadcasts the broadcast scene.

[Step S <b> 37] The display control unit 210 waits for an operation input to a switch button for switching to a television image that broadcasts a broadcast scene to be viewed displayed on the display 310.
When the operation input is accepted, the process of step S38 is executed.

[Step S38] The display control unit 210 causes the display 310 to display a television image that broadcasts a broadcast scene to be viewed.
In this way, the user can view the broadcast scene without missing the broadcast scene to be viewed.

  In the second embodiment, in the detected background sound information holding unit 201, the detected keyword sound information holding unit 202, and the detected image information holding unit 203 in FIG. The case where “ABC (player name)” and “ABC (player name) face image” are set has been described. The detection target is not limited to these three types of settings, but can be a detection target included in a broadcast scene to be viewed. However, by setting a plurality of types of detection targets rather than one type, it is possible to improve the detection accuracy of the broadcast scene being viewed. Further, the detection order may be freely changed.

  For example, when a user wants to watch a broadcast scene of a person such as a specific player or a specific singer in a sports broadcast, a song program, etc., not only the name (its pronunciation) of the person in the detected keyword sound information holding unit 202 but also a detected image By setting the face image of the person as a detection target in the information holding unit 203, it is possible to accurately detect that the person is broadcasting a broadcast scene that is actually displayed. As another example, when watching a scoring scene such as a home run or goal in a broadcast of a game such as baseball or soccer, it is conceivable that a live announcer says “home run” or “goal”. Therefore, in FIG. 5, it is conceivable that the detected keyword sound information holding unit 202 sets “home run” or “goal” (both not shown) as a detection target. Furthermore, since it is conceivable that cheers will be raised from the audience at the “home run” and “goal”, by setting “cheers” in the detected background sound information holding unit 201, the broadcasting scene of the score is actually set. It is possible to detect where the broadcast is taking place.

  In the mobile terminal device 100, the audio information and video information extracted by the audio extraction unit 204 and the video extraction unit 205 by the background sound determination processing unit 206, the keyword sound determination processing unit 207, and the image determination processing unit 208 are included in the viewing target. It is determined whether background sound, keyword sound, and face image information included in the broadcast scene are included. The broadcast notification control unit 209 notifies the display control unit 210 that a broadcast scene is being broadcast based on the determination status of each determination processing unit. When the display control unit 210 is notified that a broadcast scene is being broadcast, the display control unit 210 performs a display that causes the display 310 to switch the display to a television image that broadcasts the broadcast scene.

  As a result, the user can know that the designated broadcast scene is being broadcast, and since the display is switched to the television image on which the broadcast scene is broadcast, the user can watch the broadcast scene without missing it. become able to.

In addition, by performing a plurality of detection settings included in the broadcast scene to be viewed, the detection accuracy that the broadcast scene to be viewed is being broadcast is improved.
Further, the above processing functions can be realized by a computer. In that case, a program describing the processing contents of the functions that the computer should have is provided. By executing the program on a computer, the above processing functions are realized on the computer.

  The program describing the processing contents can be recorded on a computer-readable recording medium. Examples of the computer-readable recording medium include a magnetic storage device, an optical disk, a magneto-optical storage medium, and a semiconductor memory. Magnetic storage devices include HDDs, flexible disks (FD), magnetic tapes (MT) and the like. Optical discs include DVD (Digital Versatile Disc), DVD-RAM, CD-ROM (Compact Disc-Read Only Memory), CD-R (Recordable) / RW (ReWritable), and the like. Magneto-optical storage media include MO (Magneto-Optical disk). Semiconductor memory includes flash memory such as USB (Universal Serial Bus) memory.

  When the program is distributed, for example, a portable recording medium such as a DVD or CD-ROM in which the program is recorded is sold. It is also possible to store the program in a server computer and transfer the program from the server computer to another computer via a network.

  The computer that executes the program stores, for example, the program recorded on the portable recording medium or the program transferred from the server computer in its own storage device. Then, the computer reads the program from its own storage device and executes processing according to the program. The computer can also read the program directly from the portable recording medium and execute processing according to the program. In addition, each time the program is transferred from the server computer, the computer can sequentially execute processing according to the received program.

  Also, part or all of the processing described by the program can be replaced with an electronic circuit. For example, at least a part of the above processing functions may be realized by an electronic circuit such as a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), or a PLD (Programmable Logic Device).

  Note that various modifications can be made to the above-described embodiment without departing from the gist of the embodiment.
