Description

[Technical Field]

[0001] The present invention relates to a display control device, a display control method, and a display control program. [Background technology]

[0002] The broadcast master transmission system is a system for transmitting programs at a predetermined timing based on the date and time. The broadcast master transmission system transmits broadcast materials input from an input source device to a transmitting station or the like via an output destination device.

[0003] Broadcast materials are information corresponding to broadcast content, including, for example, video, audio, and auxiliary data. An input source device is a device that receives broadcast materials from, for example, a material bank, an editing device, or a camera used outdoors. An output destination device is a device that transmits broadcast materials to, for example, a transmitting station or a material bank.

[0004] Some faults that can occur in a broadcast master transmission system will resolve themselves, while others, such as equipment failures, will not resolve themselves. Furthermore, some faults may prevent programs from being transmitted normally. For this reason, broadcast master transmission systems are generally configured with redundancy to prepare for faults that will not resolve themselves.

[0005] A user can know that a fault has occurred in the active system by checking the alarm screen displayed by an alarm monitoring device that monitors system faults. If the fault is displayed on the alarm screen and the fault requires a switchover of the active system, the user can display a UI (User Interface) for switching systems on the master screen and switch the active system to the standby system. Note that the alarm screen is usually a different screen from the master screen. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] International Publication No. 2009 / 125817 [Patent Document 2] Japanese Patent Application Publication No. 10-224666 Summary of the Invention [Problem to be solved by the invention]

[0007] However, with the above method, the user must check the alarm on the alarm screen, operate the console to display the UI for switching systems on the master screen, and then switch systems. However, using different screens for checking the alarm and switching systems is time-consuming for the user. As a result, it takes time from the occurrence of a failure to recovery.

[0008] Patent Documents 1 and 2 do not describe a configuration for quickly recovering from a failure that occurs in the broadcast master transmission system.

[0009] An object of the present invention is to provide a display control device, a display control method, and a display control program that enable recovery operations for a failure to be performed in a shorter time. [Means for solving the problem]

[0010] In one aspect of the present invention, a display control device includes an input unit into which a fault alarm indicating that a fault has occurred in a monitored device is input, and a display control unit that, when the fault alarm is input, causes a display means to display a screen including a screen item for instructing the display of a system switching image for switching the system to be operated.

[0011] In another aspect of the present invention, the display control method displays, when a fault alarm indicating that a fault has occurred in a monitored device, a screen including a screen item for instructing the display of a system switching image for switching the system to be operated, on a display means.

[0012] In another aspect of the present invention, the display control program causes a computer to realize an input function for inputting a fault alarm indicating that a fault has occurred in the monitored device, and a display control function for displaying on a display means a screen including a screen item for instructing the display of a system switching image for switching the system to be operated when the fault alarm is input. [Effects of the Invention]

[0013] According to the present invention, it is possible to carry out a recovery operation for a failure in a shorter time. [Brief explanation of the drawings]

[Figure 11] FIG. 2 is a diagram illustrating an example of a hardware configuration according to each embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0015] [First embodiment] A first embodiment of the present invention will be described.

[0016] 1 shows an example of the configuration of a display control device 10 of this embodiment. The display control device 10 of this embodiment includes an input unit 11 and a display control unit 12.

[0017] A fault alarm indicating that a fault has occurred in a monitored device is input to the input unit 11. When a fault alarm is input, the display control unit 12 causes the display means to display a screen including a screen item for instructing the display of a system switching image for switching the system to be operated.

[0018] By configuring the display control device 10 in this manner, when a fault alarm is input, the display control device 10 causes the display means to display a screen including a screen item for instructing the display of a system switching image for switching the operating system. As a result, when a fault alarm is input, the display control device 10 causes the display means to display a screen including a screen item for instructing the display of a system switching image, thereby enabling the user to more quickly perform an operation for instructing the display of a system switching image. As a result, it becomes possible to perform a recovery operation for the fault in a shorter time.

[0019] Next, FIG. 2 shows an example of the operation of the display control device 10 of this embodiment.

[0020] A fault alarm indicating that a fault has occurred in a monitored device is input to the input unit 11. When a fault alarm is input, the display control unit 12 causes the display means to display a screen including a screen item for instructing to display a system switching image (step S101).

[0021] By operating in this manner, the display control device 10 causes the display means to display a screen including a screen item for instructing the display of a system switching image for switching the operating system when a fault alarm is input. As a result, the display control device 10 causes the display means to display a screen including a screen item for instructing the display of a system switching image when a fault alarm is input, thereby enabling the user to more quickly perform an operation for instructing the display of a system switching image. As a result, it becomes possible to perform a recovery operation for the fault in a shorter time.

[0022] As described above, in the first embodiment of the present invention, when a fault alarm is input, the display control device 10 causes the display means to display a screen including a screen item for instructing the display of a system switching image for switching the operating system. As a result, when a fault alarm is input, the display control device 10 causes the display means to display a screen including a screen item for instructing the display of a system switching image, thereby enabling the user to more quickly perform an operation for instructing the display of a system switching image. Therefore, it becomes possible to perform a recovery operation for the fault in a shorter time.

[0023] [Second embodiment] Next, a display control device 20 according to a second embodiment of the present invention will be described.

[0024] 3 shows an example of the configuration of a system including a display control device 20 of this embodiment. The display control device 20 is connected to the display means 40, the switching control means 60, a status management device 71, and an alarm monitoring device 72. The first system 51 is connected to the switching control means 60, the status management device 71, and the alarm monitoring device 72. The second system 52 is connected to the switching control means 60, the status management device 71, and the alarm monitoring device 72. The display control device 20 may have one or more functions of the status management device 71, the alarm monitoring device 72, and the switching control means 60.

[0025] The display control device 20 causes the display means 40 to display a screen including information relating to the first system 51 and the second system 52. The display control device 20 receives the information relating to the first system 51 and the second system 52 from the status management device 71 and the alarm monitoring device 72.

[0026] The state management device 71 manages information relating to the first system 51 and the second system 52. The information managed by the state management device 71 is information included in a screen to be displayed on the display means 40, such as information indicating whether the first system 51 or the second system 52 is in operation. The display control device 20 causes the display means 40 to display a screen including information relating to the first system 51 and the second system 52 based on the information acquired from the state management device 71.

[0027] The alarm monitoring device 72 monitors for faults in the first system 51 and the second system 52. For example, the alarm monitoring device 72 receives an alarm indicating a fault state from each of the devices included in the first system 51 and the second system 52. Alternatively, the alarm monitoring device 72 may inquire about the fault state of each of the devices included in the first system 51 and the second system 52 at a predetermined timing.

[0028] Furthermore, the alarm monitoring device 72 may determine that the failure of the device that sent the notification has been resolved when it receives a recovery notification indicating that the failure has been resolved. Furthermore, if the device in which the failure occurred periodically transmits an alarm while the failure is occurring, the alarm monitoring device 72 may determine that the failure has been resolved when it has not received an alarm indicating a failure state for a predetermined period of time or longer.

[0029] Furthermore, when an input command to reset an alarm is received, the alarm monitoring device 72 may determine that the device for which the reset command was received is no longer in a faulty state. The input command to reset an alarm is received in response to a user's operation on the alarm monitoring device 72 or another device. Furthermore, the alarm monitoring device 72 determines that the fault has been resolved when the operating system is switched by the switching control means 60.

[0030] The first system 51 and the second system 52 are systems whose information is displayed on the display means 40 by the display control device 20. Information relating to the first system 51 and the second system 52 is managed by a status management device 71. In addition, the fault states of the first system 51 and the second system 52 are monitored by an alarm monitoring device 72.

[0031] The first system 51 and the second system 52 are, for example, broadcast master transmission systems. The first system 51 and the second system 52 are configured as redundant systems, with one being used as a working system and the other being used as a backup system. The number of backup systems may be one or more than two.

[0032] When the first system 51 and the second system 52 are broadcast master transmission systems, the fault alarms include hardware alarms and software alarms. The broadcast master transmission system also includes devices such as a business broadcasting system, a DS (Data Server), an APS (Automatic Program Control System), an SI (Service Information) generation / transmission device, a subtitle transmission device, a data content transmission device, a scrambling device, an ENC (Encoder), a MUX (Multiplexer), an NDS (Node Station: status sharing management device), and a SW (Switcher: video signal switcher).

[0033] Hardware alarms are alarms related to physical failures or abnormalities in devices within the broadcast master transmission system. Hardware alarms include, for example, the following types of alarms: Abnormalities in equipment within the device (fan abnormalities, CPU processing abnormalities, temperature abnormalities, calculation abnormalities, power supply abnormalities, built-in board abnormalities, etc.) -Power supply failure of the device Input signal abnormality ·Line abnormality Software-related alarms are alarms related to applications and software of devices within the broadcast master transmission system. Software-related alarms include, for example, the following types of alarms: File format error File interface error Sequence abnormalities System control abnormality Data processing error Application abnormality - Generated data error Health check abnormality ·timeout -Data transmission error ·Time abnormality These are abnormalities that may prevent normal program transmission from continuing, and may be resolved by switching the system from the active system to the standby system.

[0034] The switching control means 60 switches the system to be operated to either the first system 51 or the second system 52. For example, when the switching control means 60 receives an alarm from the first system 51 indicating that a fault has occurred while the first system 51 is in operation, the switching control means 60 switches the system to be operated to the second system 52 (automatic switching). Furthermore, when the switching control means 60 receives a switching instruction output from the display control device 20 instructing the switching of the system to be operated, the switching control means 60 switches the system to be operated (manual switching). Note that automatic switching can be disabled by setting.

[0035] The switching control means 60, for example, operates the first system 51 and the second system 52 in parallel. The switching control means 60 switches the systems by switching the signals output to the subsequent stages of the first system 51 and the second system 52 to the output signal of the first system 51 or the output signal of the second system 52. Alternatively, the switching control means 60 may switch the systems by putting the inactive system of the first system 51 or the second system 52 into a sleep state and canceling the sleep state of the active system.

[0036] The display means 40 displays a screen in accordance with information from the display control device 20. The display means 40 may include a display or the like as an output device, or may include a touch panel or the like as an input / output device.

[0037] Next, the display control device 20 of this embodiment will be described with reference to Fig. 4. The display control device 20 of this embodiment includes an input unit 21, a display control unit 22, and a switching instruction unit 23.

[0038] A fault alarm indicating that a fault has occurred in a monitored device is input to the input unit 21. The monitored device is a device included in the first system 51 or the second system 52. The fault alarm is input to the display control device 20 from the alarm monitoring device 72. Furthermore, a switching instruction input instructing switching of the system to be operated is input to the input unit 21 in response to a user operation.

[0039] When a fault alarm is input, the display control unit 22 causes the display means 40 to display a screen including a screen item for instructing the display of a system switching image for switching the operating system. The display control unit 22 acquires information to be displayed on the screen from the status management device 71 and reflects it on the screen. Hereinafter, the screen item for instructing the display of a system switching image will be referred to as a system switching item.

[0040] When the inputted fault alarm indicates a predetermined type of alarm, the display control unit 22 may cause the display means 40 to display a screen including a system switching item. For example, the display control unit 22 may cause the display means 40 to display a screen including a system switching item when the inputted fault alarm indicates a serious fault, according to a table that classifies types of faults according to whether they are serious or not. A serious fault is, for example, a fault in which normal program transmission cannot be continued while the fault is occurring, and which may be resolved by switching the system.

[0041] Alternatively, the display control unit 22 may display a screen including a system switching item on the display means 40 when the fault alarm contains information indicating that the fault is serious, depending on the information included in the fault alarm as to whether the fault is serious. The display control unit 22 may also store the information included in the fault alarm as to whether the fault is serious in a storage means (not shown) in association with information on the type of fault. In this case, the display control unit 22 may refer to the information stored in the storage means when the information on whether the fault is serious is not included in the fault alarm. The display control unit 22 may also display a screen including a system switching item on the display means 40 when information indicating that the fault is serious is associated with the type of fault indicated by the fault alarm.

[0042] Furthermore, when a system switching image display instruction is input, the display control unit 22 causes the display means 40 to display a screen including a system switching image.

[0043] When a switching instruction input is input, the switching instruction unit 23 outputs a switching instruction output to the switching control means 60 to instruct the switching of the system to be operated.

[0044] Next, examples of screens that the display control device 20 causes the display means 40 to display are shown in FIGS.

[0045] 5 is an example of an initial screen. In the screen shown in FIG. 5, screen items for specifying an image to be displayed in the main image display area 86 are displayed in the shortcut display area 81. When an image display instruction is input in response to an operation of selecting a screen item displayed in the shortcut display area 81, the display control unit 22 causes the display means 40 to display a screen including the image specified in the display instruction. For example, when an image display instruction is input in response to an operation of selecting the screen item "APS control cut-in / cut-out," the display control unit 22 causes the display means 40 to display a screen including the image of "APS control cut-in / cut-out."

[0046] The user can set which screen item for instructing the display of an image is to be displayed in the shortcut display area 81. The screen item for instructing the display of an image is hereinafter referred to as a shortcut. When an instruction to display a shortcut setting image is input in response to an operation to select the shortcut setting item 82, the display control unit 22 causes the display means 40 to display a screen including a shortcut setting image that shows a UI related to shortcut setting. The user can make settings for the shortcut display area 81 by operating the display control device 20 while the screen including the shortcut setting image is displayed on the display means 40.

[0047] In the example shown in FIG. 5, five shortcuts are displayed in the shortcut display area 81, but six or more shortcuts may be set as shortcuts that can be displayed in the shortcut display area 81.

[0048] For example, shortcuts displayed in the shortcut display area 81 are referred to as displayed shortcuts, and the maximum number of displayed shortcuts is referred to as the maximum display number. Also, shortcuts set as shortcuts that can be displayed in the shortcut display area 81 are referred to as set shortcuts, and the number of set shortcuts is referred to as the set number. In this case, if the set number is equal to or less than the maximum display number, the set number of set shortcuts are displayed in the shortcut display area 81.

[0049] Furthermore, if the number of settings is greater than the maximum number to be displayed, the maximum number of set shortcuts to be displayed (five in the example of FIG. 5) are displayed in the shortcut display area 81. In this case, if an instruction to change the shortcuts to be displayed is input in response to an operation on a screen item for changing the shortcuts to be displayed, the display control unit 22 changes the shortcuts to be displayed in the shortcut display area 81.

[0050] For example, suppose that 10 shortcuts are set as setting shortcuts and the maximum number that can be displayed is 5. In this case, the display control unit 22 displays five of the first to tenth setting shortcuts, for example, the first to fifth setting shortcuts, in the shortcut display area 81. Furthermore, if an instruction is input to change the displayed shortcut to the next one, the display control unit 22 displays the second to sixth setting shortcuts in the shortcut display area 81.

[0051] Fig. 6 is an example of a screen including a screen item for instructing to display a system switching image. In the screen shown in Fig. 6, the screen item for instructing to display a system switching image is displayed at the left end of the shortcut display area 81. Hereinafter, the screen item for instructing to display a system switching image will be referred to as a system switching item 83.

[0052] For example, the display control unit 22 displays the system switching item 83 at a predetermined position in the shortcut display area 81. The predetermined position may be a fixed position (for example, the left end or the right end) in the shortcut display area 81. In this case, the display control unit 22 may display the system switching item 83 instead of a setting shortcut that should originally be displayed at the predetermined position. For example, when the predetermined position is the left end, the display control unit 22 may display the system switching item 83 instead of the first setting shortcut, and may display the second and subsequent setting shortcuts at the positions of the second and subsequent displayed shortcuts.

[0053] Furthermore, the display control unit 22 may display the system switching item 83 at a predetermined position and move the setting shortcuts that should have been displayed at the predetermined positions. For example, the display control unit 22 may display the system switching item 83 at the position of the first display shortcut and the first and subsequent setting shortcuts at the positions of the second and subsequent display shortcuts.

[0054] Furthermore, if the number of settings is smaller than the maximum number to be displayed, the predetermined position may be a position where no setting shortcuts are displayed in the shortcut display area 81. For example, if the maximum number to be displayed is 5 and the number of settings is 3, the display control unit 22 may display the first to third setting shortcuts at the positions of the first to third display shortcuts, and the system switching item 83 at the position of the fourth display shortcut.

[0055] Furthermore, when an instruction to change the shortcut to be displayed is input, the display control unit 22 may continue to display the system switching item 83 in the same position. Alternatively, the display control unit 22 may move the position where the system switching item 83 is displayed in response to an instruction to change the shortcut to be displayed.

[0056] Furthermore, the display control unit 22 displays the system switching item 83, which is displayed when a fault alarm is input, in a different display format from other screen items, for example, in a different background color or a different character color. This allows the user to more quickly recognize that a fault alarm has been input. Furthermore, since the same screen item can be used to both notify the user that a fault alarm has been input and to allow the user to input an instruction to display a system switching image, it becomes possible for the user to more quickly perform the operation to instruct the system switching image to be displayed.

[0057] FIG. 7 is an example of a screen including a system switching image 84.

[0058] The system switching image 84 includes a status display area 85 that indicates the status of the system. In the example of Fig. 7, the status display area 85 indicates that the system "SYS1" is set as the active system, the system "SYS2" is set as the backup system, and that no system is in test mode.

[0059] Furthermore, the system switching image 84 includes a screen item (switching instruction item 87) for inputting a switching instruction to instruct switching of the system. When a switching instruction input instructing switching of the system to be operated is input, the switching instruction unit 23 outputs a switching instruction output instructing switching of the system to be operated to the switching control means 60. The switching instruction input is input to the display control device 20, for example, in response to an operation by the user to select the switching instruction item 87 and further select a screen item ("Execute") for instructing execution of the setting change.

[0060] 7, the system switching image 84 also includes a screen item ("Test Switch") for switching the standby system to test mode. When the screen item "Test Switch" is selected, a display ("SYS2") indicating that the standby system "SYS2" is in test mode is displayed in the position of the status display area 85 that indicates the test status. In this state, when an instruction to switch the standby system to test mode is input in response to an operation of selecting the screen item "Execute," the switching instruction unit 23 instructs the switching control means 60 to switch the standby system to test mode.

[0061] In addition, in the example of Figure 7, information about the switching mode is displayed. If the switching mode is "AUTO", it indicates that automatic system switching is enabled. If the switching mode is "MANU", it indicates that automatic system switching is disabled.

[0062] By configuring the display control device 20 in this manner, when a fault alarm is input, the display control device 20 causes the display means to display a screen including a screen item for instructing the display of a system switching image for switching the operating system. As a result, when a fault alarm is input, the display control device 20 causes the display means to display a screen including a screen item for instructing the display of a system switching image, thereby enabling the user to more quickly perform an operation for instructing the display of a system switching image. As a result, it becomes possible to perform a recovery operation for the fault in a shorter time.

[0063] Next, an example of the operation of the display control device 20 of this embodiment will be described with reference to Fig. 8 to Fig. 10. Fig. 8 shows an example of the operation of the display control device 20 with respect to the shortcut display area 81. Fig. 9 shows an example of the operation of the display control device 20 with respect to the main image display area 86. Fig. 10 shows an example of the operation of the display control device 20 with respect to system switching.

[0064] When a fault alarm is input, the display control unit 22 causes the display means 40 to display a screen including the system switching item 83 (step S201 in FIG. 8). The display control unit 22 causes the system switching item 83 to be displayed in the shortcut display area 81.

[0065] Furthermore, when a display cancellation condition for the system switching item 83 is satisfied while a screen including the system switching item 83 is displayed on the display means 40, the display control unit 22 causes the display means 40 to terminate the display of the screen including the system switching item 83 (step S202). The display cancellation condition is satisfied when the failure is resolved, when a system switching image display instruction is input, or when system switching (automatic switching or manual switching) is executed by the switching control means 60. The display control unit 22 causes the display means 40 to terminate the display of the screen including the system switching item 83 by causing the display means 40 to display a screen in which a normal shortcut is displayed in the shortcut display area 81.

[0066] Furthermore, when a system switching image display instruction is input while a home image or another image is displayed in the main image display area 86, the display control unit 22 causes the display means 40 to display a screen in which the system switching image 84 is displayed in the main image display area 86 (steps S203 and S208 in FIG. 9). The system switching image display instruction is input in response to the system switching item 83 being selected by a user operation while the system switching item 83 is displayed in the shortcut display area 81.

[0067] The home image is an image displayed in the main image display area 86 on the initial screen. Other images are images other than the system switching image 84 that are displayed in the shortcut display area 81 and are subject to display instructions by shortcuts.

[0068] Furthermore, when a switching instruction input is input while the system switching image 84 is displayed in the main image display area 86 (step S301 in FIG. 10), the switching instruction unit 23 outputs a switching instruction output to the switching control means 60 to instruct switching of the system to be operated (step S302). The switching instruction input is input in response to a user operation while an image including the system switching image 84 is displayed on the display means 40.

[0069] Furthermore, when an instruction to display another image is input while the home image or system switching image 84 is displayed in the main image display area 86, the display control unit 22 causes the display means 40 to display a screen including the specified image (steps S204 and S205 in FIG. 9). The instruction to display another image is input in response to a shortcut displayed in the shortcut display area 81 being selected by a user operation.

[0070] Furthermore, when an instruction to display a home image is input, the display control unit 22 causes the display means 40 to display a screen including the home image (steps S206 and S207).

[0071] By operating in this manner, the display control device 20 causes the display means to display a screen including a screen item for instructing the display of a system switching image for switching the operating system when a fault alarm is input. As a result, the display control device 20 causes the display means to display a screen including a screen item for instructing the display of a system switching image when a fault alarm is input, thereby enabling the user to more quickly perform an operation for instructing the display of a system switching image. As a result, it becomes possible to perform a recovery operation for the fault in a shorter time.

[0072] As described above, in the second embodiment of the present invention, when a fault alarm is input, the display control device 20 causes the display means to display a screen including a screen item for instructing the display of a system switching image for switching the operating system. As a result, when a fault alarm is input, the display control device 20 causes the display means to display a screen including a screen item for instructing the display of a system switching image, thereby enabling the user to more quickly perform an operation for instructing the display of a system switching image. Therefore, it becomes possible to perform a recovery operation for the fault in a shorter time.

[0073] [Hardware configuration example] An example of the configuration of hardware resources for realizing the display control device (10, 20) in each of the above-described embodiments of the present invention using one information processing device (computer) will be described. Note that the display control device may be realized physically or functionally using at least two or more information processing devices. Also, the display control device may be realized as a dedicated device, or a general-purpose device. Also, only some of the functions of the display control device may be realized using an information processing device.

[0074] 11 is a diagram illustrating an example of the hardware configuration of an information processing device that can realize the display control device according to each embodiment of the present invention. The information processing device 90 includes a communication interface 91, an input / output interface 92, a calculation device 93, a storage device 94, a nonvolatile storage device 95, and a drive device 96.

[0075] 1 can be realized by a communication interface 91 and an input / output interface 92. Furthermore, the display control unit 12 can be realized by a calculation device 93.

[0076] The communication interface 91 is a communication means for the display control device of each embodiment to communicate with an external device at least in a wired or wireless manner.
