Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings to be referred to below, for the sake of convenience, the main part that is the subject of the description is exaggerated as appropriate, and other than the main part is appropriately simplified or omitted.
FIG. 1 is a block diagram showing a configuration of an emergency information display system as an embodiment of the present invention. In FIG. 1, television broadcasts each including an emergency broadcast flag detection unit 120 as an emergency index information detection unit that detects emergency index information (emergency broadcast flag) indicating emergency broadcast included in a television broadcast reception signal. A plurality of receiving circuits 130 (131 and 132 are illustrated in FIG. 1) are provided with the antenna 110 in common.

  A display that displays video or data via the display driver circuit 140 based on the output of one or more of the television broadcast receiving circuits 130 (131, 132: a digital television receiving circuit is shown) 150 is provided. In addition, among the plurality of television broadcast receiving circuits 130 (131, 132), its own emergency index information detection unit (emergency broadcast flag detection unit) 120 precedes other television broadcast reception circuits (eg, 132). In response to the detection output of the emergency indicator information detection unit 120 of one television broadcast receiving circuit (for example, 131) that has detected the emergency indicator information, the display form on the display device 150 is switched to the multi-screen display and the most in the multi-screen display. A system controller 160 that displays one emergency broadcast related to the detection output on the main screen with high visibility is provided.

  In addition to the control operations described above, the system controller 160 controls the entire system as a whole. Also, the system controller 160 can be operated by the user (in addition to direct operation on the operation element, input from the remote controller). An operation reception unit 170 for receiving (receivable) is connected, through which the operation from the user is recognized and a required response is made.

  FIG. 2 is a flowchart showing the operation of the emergency information display system of FIG. FIG. 2 (A) is a flowchart until the emergency broadcast by the digital television receiving circuit that is initially detected to have an emergency broadcast flag is displayed on the main screen of the multi-screen, and FIG. It is a flowchart showing the detail of the operation | movement which receives the emergency broadcast which is broadcasts other than the broadcast with which the flag of the emergency broadcast was initially set in the process of the operation | movement flow of FIG. 2 (A).

When the system is activated, the television broadcast receiving circuit 130 receives the broadcast under the control of the system controller 160 (step S201). The emergency broadcast flag detectors 120 and 120 of the television broadcast receiving circuit 130 monitor the timing at which the emergency broadcast flag is set (step S202).
In step S202, the emergency indicator information detection unit 120 in one television broadcast receiving circuit (eg, 131) of the plurality of television broadcast receiving circuits 130 (131, 132) recognizes that an emergency broadcast flag has been set. In some cases, the system controller 160 fixes the channel selection state of the television broadcast receiving circuit (eg, 131) for which the emergency broadcast flag is set, and activates the channel selection scan operation in the other television broadcast receiving circuit (eg, 132). (Step S203).

  Further, a control command is issued to each television broadcast receiving circuit 130 (131, 132) and the display driver circuit 140 to switch the screen of the display 150 to multi-screen display (mode) (step S204). Among the multi-screen displays, an emergency broadcast received by one television broadcast receiving circuit (for example, 131) that is initially recognized to have an emergency broadcast flag is displayed as the main screen having the highest visibility in the multi-screen display. (Step S205).

On the other hand, the channel selection scan operation in the other television broadcast receiving circuit (eg, 132) activated in step S203 proceeds as shown in the flowchart of FIG. Scanning is performed by sequentially switching the channel selection in another television broadcast receiving circuit (for example, 132) (S211), and it is determined whether the emergency flag is set in the sequential channel selection state (S212).
For the television broadcast receiving circuit 130 in which it is detected in step S212 that the emergency flag is raised, the channel selection state in that state is fixed and displayed on the sequential sub-screens in the multi-screen (S213). . When all the sub-screens assigned to the multi-screen are satisfied, the repetition of the scanning operation by sequentially switching the channel selection in another television broadcast receiving circuit (for example, 132) ends (S214). Various modifications can be considered for the process up to step S214, which will be described in detail later with reference to a flowchart.

FIG. 3 is a diagram illustrating an example of multi-screen display. In this example, there are three main screens 151 that occupy the area that slightly exceeds the left half of the screen on the entire mute screen 150, and three vertically aligned rectangles in the remaining display area on the right side of the screen. The sub-screens 152, 153, and 154 constitute a multi-screen.
Of the multi-screen display in step S204 in the flowchart of FIG. 2A, the channel selection state of one television broadcast receiving circuit (for example, 131) that was initially recognized as having been flagged for emergency broadcasting is It is fixed (step S203), and the emergency broadcast is displayed on the main screen 151 with the highest visibility (step S205). Since the emergency broadcast first received by the television broadcast receiving circuit 131 that selects the broadcast that is performing the emergency broadcast is displayed on the main screen with the highest visibility in the multi-screen display, Can be recognized without delay without overlooking.

  In the television broadcast receiving circuit (132, etc.) other than the one television broadcast receiving circuit (131 in the above example) displaying the emergency broadcast on the main screen 151, as described above with respect to the flowchart of FIG. An operation for searching for emergency broadcasts other than the emergency broadcast on the main screen 151 by the action of the emergency indicator information detection unit (emergency broadcast flag detection unit) 120 is executed while sequentially switching the channel selection state (steps S211 and S212). As a result, each emergency broadcast by the sequential broadcast whose detection output is obtained by the emergency broadcast flag detection unit 120 is displayed on the sequential sub-screens 152, 153, 154 other than the main screen in the multi-screen (step S213). In this case, if the number of television broadcast receiving circuits corresponding to the number of sub-screens is provided, all the sub-screens can display moving images, but the number of television broadcast receiving circuits is less than that. Even in such a case, it is possible to display a screen satisfying the total number of sub-screens by taking various methods such as those shown below, such as displaying a part of a moving image and displaying a still image in the other part.

  The search and display control described above is executed under the control of the television broadcast receiving circuit 130 and the display driver circuit 140 by the system controller. Since emergency broadcasts other than the emergency broadcast on the main screen 151 are also viewed on the sub-screens 152, 153, and 154, emergency information is acquired from an emergency broadcast that differs from the broadcast displayed on the main screen 151 and the content of the report. It is possible to collect information that is not biased to one station.

  FIG. 4 is a flowchart showing the operation of the modification of the embodiment described with reference to the flowchart of FIG. In the example of FIG. 4, when the number of emergency broadcasts to be displayed on the sub screens 152, 153, and 154 exceeds the number of sub screens that can be displayed effectively, the system controller 160 is within the limit that can be displayed effectively. The other emergency broadcasts are sequentially and cyclically switched every predetermined time on a number of sub-screens (three in FIG. 3).

  That is, step S401 in the flowchart in FIG. 4 corresponds to step S203 in the flowchart in FIG. 2A and step S211 in the flowchart in FIG. That is, what will be described based on the flowchart of FIG. 4 is partially different in details of the operation of receiving emergency broadcasts other than broadcasts initially flagged for emergency broadcasts in the process of the operation flow of FIG. To do.

  Scanning is performed by sequentially switching the channel selection in another television broadcast receiving circuit (eg, 132) (S401), and the number of broadcasts in which the emergency flag is detected in the sequential channel selection state is counted (S402). ). In step S402, it is determined whether or not the number of broadcasts for which the emergency broadcast flag is set (count number) is equal to or less than the limit of the number of sub-scenes that can be effectively displayed in the multi-screen display (S403). If the result is affirmative, all emergency broadcasts other than the emergency broadcast projected on the main screen are displayed on the sequential sub-screens (S404).

  On the other hand, when it is determined in step S403 that the number of broadcasts that are flagged as emergency broadcasts (count number) exceeds the limit of the number of sub-scenes that can be effectively displayed in the multi-screen display, Sequential sub-screens for all emergency broadcasts including emergency broadcasts that exceed the limit (in principle, other than emergency broadcasts displayed on the main screen, but this does not prevent inclusion) Are sequentially switched and displayed at predetermined time intervals (S405). It becomes possible to view more types of emergency broadcasts than the number of sub-screens that can be effectively displayed, increasing the possibility of collecting emergency information from many types of news reports in various ways.

  FIG. 5 is a flowchart showing the operation of another modified example of the embodiment described with reference to the flowchart of FIG. In the example of FIG. 5, when the number of emergency broadcasts flagged as emergency broadcasts exceeds the number of digital television receiving circuits, the system controller 160 displays some emergency broadcasts while displaying other emergency broadcasts. Is to display a still image.

  That is, step S501 in the flowchart in FIG. 5 corresponds to step S203 in the flowchart in FIG. 2A and step S211 in the flowchart in FIG. That is, what will be described based on the flowchart of FIG. 5 is partially different in details of the operation of receiving an emergency broadcast that is a broadcast other than a broadcast initially flagged for emergency broadcast in the process of the operation flow of FIG. To do.

  Scanning is performed by sequentially switching the channel selection in another television broadcast receiving circuit (eg, 132) (S501), and the number of broadcasts in which the emergency flag is detected in the sequential channel selection state is counted (S502). ). Next, it is determined whether or not the number of broadcasts (count number) for which an emergency broadcast flag is set in step S502 is equal to or less than the total number of digital television receiver circuits 130 (S503). All emergency broadcasts other than the emergency broadcast projected on the screen are displayed on the sequential sub-screens (S504). Although the maximum number of sub-screens that can be secured is an example on the premise that the number of sub-screens is equal to or greater than the number of digital television receiving circuits 130, various countermeasures are conceivable even when this premise is not satisfied.

  On the other hand, if it is determined in step S503 that the number of broadcasts for which the emergency broadcast flag is set (the number of counts) exceeds the total number of the digital television receiving circuits 130, a part of the emergency broadcasts within the total number is included. While the video is displayed on the screen, the emergency broadcast that exceeds the total number (in principle, it must be other than the emergency broadcast that is projected on the main screen, but this does not preclude inclusion) A still image is displayed on the screen (S505).

When the number of emergency broadcast stations exceeds the number of television broadcast receiving circuits, it is not possible to project videos for all of these broadcasts simultaneously, but broadcasts that cannot be displayed as movies are also displayed as still images. The possibility of missing emergency broadcasts from other stations is reduced, and the possibility that emergency information can be collected from many types of news media is expanded.
The system controller 160 may be configured to supply the television broadcast receiving circuit 130 with an instruction to update an image displayed as a still image on the corresponding sub-screen over time. Each television broadcast receiving circuit 130 can also be configured to respond to such a command. In this case, even an emergency broadcast image displayed as a still image on the sub-screen is updated over time, so it is possible to know the transition of the situation with the content close to the latest state related to the emergency broadcast. become. The risk of missing important information is reduced.
