  FIG. 4 is a flowchart showing processing of the terminal device 1 according to the first embodiment of this invention. This flowchart shows processing when the terminal device 1 remotely controls the video display device 3.

  In step S <b> 401, the terminal device 1 waits for application software (hereinafter, “operation application”) for performing remote control of the video display device 3 to be started based on a user operation.

  FIG. 5 shows various display examples of the touch panel type display unit 22 of the terminal device 1. FIG. 5A shows a menu screen in which various types of application software are arranged on the terminal device 1. When the “TV” button displayed on the touch panel is pressed by the user, the operation application is activated.

  In step S402, based on a user operation, the terminal device 1 selects the video display device 3 to be subjected to remote control. FIG. 5B is a display example of a selection screen when there are two video display devices 3 that can be selected as targets for remote control. Here, “TV A” is selected.

  When the video display device 3 to be remotely controlled is selected, the terminal device 1 displays various instructions that can be transmitted to the video display device 3. FIG. 5C is a display example of the operation screen of the video display device 3 at that time.

  Next, in step S403, the terminal device 1 confirms whether or not the user has performed an operation for terminating the operation application. When the user performs an operation for ending the operation application, the terminal device 1 ends the operation of the operation application and returns to the step of displaying the menu screen.

  In step S404, the terminal device 1 confirms whether or not the power button has been pressed by the user. When the power button displayed on the terminal device 1 is pressed, the terminal device 1 transmits a power command to the video display device 3 (step S405), and is stored in the storage unit 26 of the terminal device 1 in step S406. After transmitting various setting values such as channel and volume to the video display device 3 as setting commands, the processes from step S403 are repeated.

  The terminal device 1 transmits its own identification code when transmitting various commands such as a power command and a setting command.

  The terminal device 1 transmits the setting command including the channel and various setting values stored in the storage unit 26 subsequent to the transmission of the power command to the video display device 3, so that the video display device 3 according to the setting value of the terminal device 1. Can be set. If the power button of the video display device 3 displayed on the terminal device 1 is not pressed in step S404, has the terminal device 1 been instructed to change settings other than power on / off of the video display device 3 in step S407? Check if. Setting changes other than power on / off include, for example, channel change, volume setting, image quality adjustment, and the like.

  When the setting change of the video display device 3 is instructed, the terminal device 1 transmits a setting command corresponding to the video display device 3 (step S408), and the setting value is stored in the storage unit 26 of the terminal device 1 in step S409. Remember.

Next, when the channel + button is pressed, the terminal device 1 transmits a setting command instructing addition of channels or switching to channel 2, and information indicating the channel 2 is stored in the storage unit 26. In this way, when the setting command specifies a relative value such as channel + or channel-, it is replaced with an absolute value such as channel 2, and only the final value is stored in the storage unit 26.

  Next, in step S410, the terminal device 1 receives status information sent from the video display device 3 if there is status information, and if there is information to be displayed corresponding to the status information, displays it on the display unit 22, and step S403. Repeat the process from. Whether the status information is sent to the terminal device 1 is determined by an identification code.

  FIG. 5D shows a display example of status information.

  If the setting of the video display device 3 is not instructed in step S407, the terminal device 1 repeats the processes from step S403.

  FIG. 6 is a flowchart showing the processing of the video display device 3 according to the first embodiment of the present invention. This flowchart shows processing when the video display device 3 is remotely controlled by the terminal device 1.

  In step S601, the video display device 3 waits for reception of a power command. When receiving the power command, the video display device 3 turns on the power and reflects various setting values transmitted from the terminal device 1 (step S602). In step S <b> 603, the video display device 3 stores the identification code in the storage unit 36 with the terminal device 1 that transmitted the power command as the terminal device A.

  Next, in step S604, the video display device 3 performs one screen display. The video display device 3 has a two-screen display function, and the initial state is a single-screen display.

  Next, in step S605, the video display device 3 confirms again whether the power command has been received. When the power command is received, the video display device 3 checks whether the received command is a command from the terminal device A (step S606). Whether the command is from the terminal device A can be determined by whether the identification code when the power command is received matches the identification code stored in the storage unit 36.

  In step S606, when the received power command is a command from the terminal device A, the video display device 3 turns off the power (step S607).

  In the present embodiment, toggle control is described as an example in which the video display device 3 repeats power on / off every time it receives a power command. However, the power on and power off commands may be separated.

  In step S605, when the video display device 3 has not received the power command, the video display device 3 checks whether another command other than the power command has been received (step S608). When the other command is received, the video display device 3 checks whether the received command is a command from the terminal device A (step S609).

  Other commands are, for example, setting commands for instructing channel switching and volume or brightness settings.

  In step S609, when the received command is a command from the terminal device A, the video display device 3 executes the command as instructed (step S610), and repeats the processes from step S605.

  If the received command is not a command from the terminal device A in step S609, the video display device 3 transmits status information indicating that there is no authority to change the channel or the like to the corresponding terminal device 1 (step S611). The process from step S605 is repeated. Receiving this status, the terminal device 1 displays on the display unit 22 that there is no authority to execute the command. FIG. 5D shows an example in which there is no authority to change the channel.

  When sending status information to the terminal device 1, the video display device 3 may send the identification code when receiving the command in step S608 together with the status information. Accordingly, the terminal device 1 that has received the status information can determine whether or not the display as shown in FIG.

  If no other command is received in step S608, the video display device 3 repeats the processes from step S605.

  If the received command is not a command from the terminal device A in step S606, the video display device 3 stores the identification code in the storage unit 36 with the terminal device 1 as the terminal device B (step S616). ).

  Next, in step 617, the video display device 3 performs two-screen display of screen A and screen B. The screen A can be remotely controlled by the terminal device A, and the screen B can be remotely controlled by the terminal device B.

  Next, in step S618, the video display device 3 confirms whether the power command has been received again. When the power command is received, the video display device 3 checks whether the received command is a command from the terminal device A (step S620).

  In step S620, when the received command is a command from the terminal device A, the video display device 3 stores the terminal device 1 stored in the storage unit 36 as the terminal device B as the terminal device A and stores the identification code thereof. (Step S621), the processes from Step S604 are repeated.

  In step S604, the video display device 3 switches the two-screen display to the one-screen display and displays the screen B.

  If the received command is not a command from the terminal device A in step S620, the video display device 3 repeats the process from step S604.

  In step S604, the video display device 3 switches the two-screen display to the one-screen display and displays the screen A.

  If the power command is not received in step S618, the video display device 3 checks whether another command is received (step S622).

  If another command is received in step S622, the video display device 3 checks whether the received command is a command from the terminal device A (step S623).

  If the received command is a command from the terminal device A in step S623, the video display device 3 executes the command as instructed on the screen A (step S624), and then repeats the processes from step S618.

  In step S623, if the received command is not a command from the terminal device A, that is, a command from the terminal device B, the video display device 3 executes the command as instructed on the screen B (step S625). The process from step S618 is repeated.

  The command to be executed for the screen B is a setting command for instructing, for example, changing the channel of the screen B or switching the input. Setting changes common to the screen A and the screen B, such as volume and brightness, may be executed from the terminal device B or may not be executed from the terminal device B.

  If no other command has been received in step S622, the video display device 3 repeats the processes from step S618.

  Thus, for example, when a power command is sent from the first terminal device 1 to the video display device 3, the video display device 3 is turned on, and the operation can be performed only from the first terminal device 1.

  Next, when the power command is sent from the first terminal device 1 to the video display device 3, the power of the video display device 3 is turned off, but the power command is sent from the second terminal device 1 instead of from the first terminal device 1. When sent, the video display device 3 becomes a two-screen display, and operations such as channel change of the original screen can be performed only from the first terminal device 1 and operations of the added screen can be performed only from the second terminal device 1. it can.

  Further, when a power command is sent from the first terminal device 1 to the video display device 3 in this two-screen display state, the video display device 3 returns to the single screen display, and the operation is performed only from the second terminal device 1. be able to. When the power command is sent from the second terminal device 1 to the video display device 3, the video display device 3 is turned off.

  In the two-screen display state, when a power command is sent from the second terminal device 1 instead of the first terminal device 1, the video display device 3 returns to the one-screen display, and the operation is performed only from the first terminal device 1. It can be carried out. Then, when a power command is sent from the first terminal device 1 to the video display device 3, the video display device 3 is turned off.

  That is, if a power command is sent from the terminal device 1 operating the video display device 3 during one screen display, the power of the video display device 3 is turned off, but if a power command is sent from another terminal device 1, two screens are displayed. The display is switched, and the operation of the original screen can be performed only from the original terminal device 1, and the operation of the added screen can be performed only from another terminal device 1.

  When a power command is sent from one of the terminal devices 1 during the two-screen display, the video display device 3 is switched to a one-screen display, and only from a terminal device 1 different from the terminal device 1 that sent the power command. The operation can be performed.

  With the above configuration, in the first embodiment of the present invention, the channel and volume settings sent from the terminal device 1 to the video display device 3 are stored, and the stored setting values are displayed after the power command is transmitted. By transmitting to the display device 3, the video display device 3 is set to the channel or volume that was viewed last time just by the user turning on the power using the terminal device 1.

  Since various setting values are stored in the terminal device 1, a plurality of users can store the setting values of the video display device 3 in their terminal devices 1, and the video display device 3 can be stored using their terminal device 1. When the power is turned on, the video display device 3 can be set to have been viewed by the user last time. Furthermore, the settings viewed on one video display device 3 can be reflected on another video display device 3.

  Further, when a plurality of terminal devices 1 send a power command to the video display device 3, the screen of the video display device 3 is divided and displayed, and the corresponding screen can be operated from each terminal device 1.

  Then, when the power command is sent to the video display device 3 on which the screen is divided and displayed, the split display of the screen of the video display device can be terminated.

  In the present embodiment, the change of the channel is exemplified as the target of the remote control, but the change of the URL is also applicable.

  Next, a second embodiment of the present invention will be described. Note that the configuration, effects, and the like in this embodiment are the same as those in the first embodiment unless otherwise specified. For this reason, the difference between the present embodiment and the first embodiment will be mainly described below, and description of common points will be omitted as much as possible.

  FIG. 7 is a flowchart showing the processing of the video display device 3 according to the second embodiment of the present invention. This flowchart shows processing when the video display device 3 is remotely controlled by the terminal device 1.

  Steps S701 to S710 are the same as steps S601 to S610 in FIG.

  If the received command is not a command from the terminal device A in step S709, the video display device 3 stores the identification code in the storage unit 36 with the terminal device 1 that has transmitted the command as the terminal device B (see FIG. Step S711).

  Next, in step 712, the video display device 3 performs two-screen display of screen A and screen B. The screen A can be remotely controlled by the terminal device A, and the screen B can be remotely controlled by the terminal device B.

  Next, the video display device 3 executes a command as instructed on the screen B (step S713), and performs the process of step S718.

  Thus, for example, when a power command is sent from the first terminal device 1 to the video display device 3, the video display device 3 is turned on, and the operation can be performed only from the first terminal device 1.

  At this time, when an operation is performed from the second terminal device 1, the video display device 3 becomes a two-screen display, the operation of the original screen is performed only from the first terminal device 1, and the operation of the added screen is the second operation. This can be done only from the terminal device 1.

  Further, when a power command is sent from the first terminal device 1 to the video display device 3, the video display device 3 returns to the single screen display, and the operation can be performed only from the second terminal device 1.

  When a power command is sent from the second terminal device 1 instead of the first terminal device 1, the video display device 3 returns to the one-screen display, and the operation can be performed only from the first terminal device 1. Then, when a power command is sent from the first terminal device 1 to the video display device 3, the video display device 3 is turned off.

  With the configuration described above, the second embodiment of the present invention can achieve the same effects as the first embodiment.

  Further, when an operation command is sent from the plurality of terminal devices 1 to the video display device 3, the screen of the video display device 3 is divided and displayed, and the corresponding screen can be operated from each terminal device 1.

  Then, when the power command is sent to the video display device 3 on which the screen is divided and displayed, the split display of the screen of the video display device 3 can be terminated.

  Next, a third embodiment of the present invention will be described. Note that the configuration, effects, and the like in the present embodiment are the same as those in the first embodiment unless otherwise specified.

  In step S809, when the channel change command is received from the terminal device A, the video display device 3 changes the channel (step S810) and repeats the processes from step S805.

  If the received channel change command is not a command from the terminal device A in step S809, the video display device 3 performs step S811.

  Steps S811 to S812 are the same as steps S711 to S712 in FIG.

  In step S813, after changing the channel of the screen B, the video display device 3 performs the process of step S818.

  If the channel change command is not received in step S808, the video display device 3 checks whether other commands other than the power command and the channel change command have been received (step S814).

  The other command is, for example, a setting command for instructing a change in volume or brightness.

  If another command is received in step S814, the video display device 3 executes the command as instructed (step S815), and repeats the processes from step S805.

  Even if no other command is received in step S814, the video display device 3 repeats the processes from step S805.

  Steps S816 to S817 are the same as steps S616 to S617 in FIG.

  If the power command is not received in step S818, the video display device 3 checks whether a channel change command is received (step S822).

  If a channel change command is received in step S822, the video display device 3 checks whether it is a command from the terminal device A (step S823).

  In step S823, when the received command is a command from the terminal device A, the video display device 3 changes the channel of the screen A (step S824), and then repeats the processes from step S818.

  If the received command is not a command from the terminal device A in step S823, the video display device changes the channel of the screen B (step S825), and then repeats the steps from step S818.

  If the channel change command has not been received in step S822, the video display device 3 checks whether the video display device 3 has received another command (step S826).

  If another command is received in step S826, the video display device 3 executes the command as instructed (step S827), and then repeats the processes from step S818.

  Even if no other command is received in step S826, the video display device 3 repeats the process from step S818.

  In this way, for example, when a power command is sent from the first terminal device 1 to the video display device 3, the video display device 3 is turned on, and the operation is performed from the first terminal device 1 and the second terminal device 1. It can be carried out.

  However, when the channel switching operation is performed from the second terminal device 1, the video display device 3 is displayed in two screens, and the channel of the original screen is switched only from the first terminal device 1. Switching can be performed only from the second terminal device 1. Other operations can be performed from the first terminal device 1 and the second terminal device 1.

  Further, when a power command is sent from the first terminal device 1 to the video display device 3, the video display device 3 returns to the single screen display, and the operation can be performed only from the second terminal device 1.

  When the power command is sent from the second terminal device 1 instead of the first terminal device 1, the video display device 3 returns to the one-screen display, and the operation can be performed only from the terminal device 1. Then, when a power command is sent from the first terminal device 1 to the video display device 3, the video display device 3 is turned off.

  With the above configuration, the third embodiment of the present invention can obtain the same effects as those of the first embodiment.

  Further, when a channel change command is sent from the plurality of terminal devices 1 to the video display device 3, the screen of the video display device is divided and displayed, and the corresponding screen can be operated from each terminal device 1.

  Then, when the power command is sent to the video display device 3 on which the screen is divided and displayed, the split display of the screen of the video display device 3 can be terminated.

  Next, a fourth embodiment of the present invention will be described. Note that the configuration, effects, and the like in the present embodiment are the same as those in the first embodiment unless otherwise specified. Therefore, differences between the present embodiment and the first embodiment will be mainly described below.

  FIG. 9 is a flowchart showing the processing of the video display device 3 according to the fourth embodiment of the present invention. This flowchart shows processing when the video display device 3 is remotely controlled by the terminal device 1.

  Steps S901 to S905 are the same as steps S601 to S605 in FIG.

  If the power command is received in step S905, the video display device 3 turns off the power (step S907).

  In step S905, when the power command is not received, the video display device 3 confirms whether the two-screen switching command is received (step S913).

  In step S913, when the two-screen switching command is received, the video display device 3 checks whether the received command is a command from the terminal device A (step S914).

  In step S914, when the received command is a command from the terminal device A, the video display device 3 switches to the two-screen display (step S915), and then repeats the processes from step S905. In this case, the two screens can be operated only from the terminal device A.

  In this embodiment, every time the video display device 3 receives a two-screen switching command, two-screen display and one-screen display are switched. As an example, toggle control is shown. Commands may be separated.

  When the received command is not a command from the terminal device A in step S914, the video display device 3 performs the process of step S916.

  Steps S916 to S917 are the same as steps S616 to S617 in FIG.

  If the two-screen switching command has not been received in step S913, the video display device 3 checks whether other commands other than the power command and the two-screen switching command have been received (step S908).

  Other commands are, for example, setting commands for instructing channel switching and volume or brightness settings.

  In step S908, when the other command is received, the video display apparatus 3 performs the process of step S909. When the other command is not received, the process from step S905 is repeated.

  Steps S909 to S911 are the same as steps S609 to S611 in FIG.

  FIG. 12 shows various display examples of the touch panel type display unit 22 of the terminal device 1, informing that there is no authority to change the channel, displaying a message prompting switching to the two-screen display, and displaying the two-screen switching button. Is arranged. This is displayed in step S911.

  Next, in step S918, the video display device 3 confirms whether the power command has been received again. When the power command is received, the video display device 3 turns off the power (step S907).

  In step S918, when the power command is not received, the video display device 3 confirms whether the two-screen switching command is received (step S919).

  In step S919, when the two-screen switching command is received, the video display device 3 checks whether it is a command from the terminal device A (step S920).

  If the two-screen switching command has not been received in step S919, the video display device 3 checks whether any other command other than the power command and the two-screen switching command has been received (step S922).

  Steps S920 to S925 are the same as steps S620 to S625 in FIG.

  Thus, for example, when a power command is sent from the first terminal device 1 to the video display device 3, the video display device 3 is turned on, and the operation can be performed only from the first terminal device 1.

  Furthermore, when a two-screen switching command is sent from the second terminal device 1, the video display device 3 becomes a two-screen display, and the operation of the original screen is performed only from the first terminal device 1, and the operation of the added screen is the first. This can be done only from the second terminal device 1.

  Next, when a two-screen switching command is sent from the first terminal device 1, the video display device 3 becomes a one-screen display, and the operation can be performed only from the second terminal device 1.

  When a two-screen switching command is sent from the second terminal device 1, the video display device 3 becomes a one-screen display, and the operation can be performed only from the second terminal device 1.

  When the power command is sent from the first terminal device 1 or the second terminal device 2 to the video display device 3, the power of the video display device 3 is turned off.

  With the above configuration, the fourth embodiment of the present invention can achieve the same effects as those of the first embodiment.

  Further, when a two-screen switching command is sent from a terminal device 1 different from the terminal device 1 that is turned on, the screen of the video display device 3 is divided and displayed from each terminal device 1. Can be operated.

  Then, when a two-screen switching command is sent to the video display device 3 on which the screen is divided and displayed, the split display of the screen of the video display device 3 can be terminated.

  Next, a fifth embodiment of the present invention will be described. Note that the configuration, effects, and the like in the present embodiment are the same as those in the first embodiment unless otherwise specified. Therefore, differences between the present embodiment and the first embodiment will be mainly described below.

  FIG. 10 is a flowchart showing the processing of the video display device 3 according to the fifth embodiment of the present invention. This flowchart shows processing when the video display device 3 is remotely controlled by the terminal device 1.

  Steps S1001 to S1007 are the same as steps S901 to S907 in FIG.

  Steps S1008 to S1015 are the same as steps S808 to S815 in FIG.

  In step S1018, the video display device 3 checks whether a power command has been received. When the power command is received, the video display device 3 turns off the power (step S1007).

  If no power command is received in step S1018, the video display device 3 checks whether a command for instructing termination of the operation application (hereinafter, “application termination command”) is received (step S1019).

  If an application end command is received in step S1019, the video display device 3 checks whether it is a command from the terminal device A (step S1020).

  Steps S1020 to S1021 are the same as steps S620 to S621 in FIG.

  If the application end command has not been received in step S1019, the video display device 3 checks whether a channel change command has been received (step S1022).

  Steps S1022 to S1027 are the same as steps S822 to S827 in FIG.

  In this way, for example, when a power command is sent from the first terminal device 1 to the video display device 3, the video display device 3 is turned on, and the operation is performed from the first terminal device 1 and the second terminal device 1. It can be carried out.

  However, when the channel switching operation is performed from the second terminal device 1, the video display device 3 is displayed in two screens, and the channel of the original screen is switched only from the first terminal device 1. Can be switched only from the second terminal device 1. Other operations can be performed from the first terminal device 1 and the second terminal device 1.

  Further, when an application end command is sent from the first terminal device 1 to the video display device 3, the video display device 3 returns to the single screen display, and the operation can be performed only from the second terminal device 1.

  When the application end command is sent from the second terminal device 1 instead of the first terminal device 1, the video display device 3 returns to the one-screen display, and the operation can be performed only from the first terminal device 1. Then, when a power command is sent from the first terminal device 1 to the video display device 3, the video display device 3 is turned off.

  With the above configuration, the fifth embodiment of the present invention can obtain the same effects as those of the first embodiment.

  Further, when a channel change command is sent from a terminal device 1 different from the terminal device 1 to which the power of the video display device 3 is turned on, the screen of the video display device 3 is divided and displayed, and the corresponding screen is displayed from each terminal device 1. Can be operated.

  Then, when the application end command is sent to the video display device 3 on which the screen is divided and displayed, the split display of the screen of the video display device 3 can be ended.

  Next, a sixth embodiment of the present invention will be described. Note that the configuration, effects, and the like in the present embodiment are the same as those in the first embodiment unless otherwise specified. Therefore, differences between the present embodiment and the first embodiment will be mainly described below.

  FIG. 11 is a flowchart showing the processing of the video display apparatus 3 according to the sixth embodiment of the present invention. This flowchart shows processing when the video display device 3 is remotely controlled by the terminal device 1.

  Steps S1101 to S1118 are the same as steps S1001 to S1018 in FIG.

  If the power command has not been received in step S1118, the video display device 3 checks whether a channel change command has been received (step S1122).

  If a channel change command is received in step S1122, the video display device 3 checks whether it is a command from the terminal device A (step S1123).

  If the received command is a command from the terminal device A in step S1123, the video display device 3 changes the channel of the screen A (step S1124) and performs the process of step S1128.

  If the received command is not a command from the terminal device A in step S1123, the video display device 3 changes the channel of the screen B (step S1125) and performs the process of step S1128.

  If the channel change command has not been received in step S1122, the video display device 3 performs the process of step S1126.

  Steps S1126 to S1127 are the same as steps S826 to S827 in FIG.

  Next, in step S1128, the video display device 3 confirms whether or not the changed channel of the screen A matches the channel of the screen B.

  Next, when the channels match in step S1128, the video display device 3 changes to a single screen display to display video content based on the channels (step S1104).

  If the channels do not match in step S1128, the video display device 3 repeats the processes from step S1118 and continues the two-screen display.

  Thus, for example, when a power command is sent from the first terminal device 1 to the video display device 3, the video display device 3 is turned on, and the operation is performed from the first terminal device 1 and the second terminal device 2. It can be carried out.

  However, when the channel switching operation is performed from the second terminal device 2, the video display device 3 becomes a two-screen display, and the operation of the original screen is performed only from the first terminal device 1, and the operation of the added screen is the first. This can be done only from the second terminal device 1.

  Further, when the channels of the two screens match, the video display device 3 returns to the single screen display.

  When the power command is sent from the first terminal device 1 or the second terminal device 1 to the video display device 3, the video display device 3 is turned off.

  With the above configuration, the sixth embodiment of the present invention can achieve the same effects as the first embodiment.

  Further, when a channel operation command is sent from a terminal device 1 different from the terminal device 1 that is turned on, the screen of the video display device 3 is divided and displayed, and the corresponding screen is displayed from each terminal device 1. Can be operated.

  When the channels of the two screens match, the split display of the screen of the video display device 3 can be terminated.

  Next, a seventh embodiment of the present invention will be described. Note that the configuration, effects, and the like in the present embodiment are the same as those in the first embodiment unless otherwise specified. Therefore, differences between the present embodiment and the first embodiment will be mainly described below.

  FIG. 13 is a flowchart showing processing of the terminal device 1 according to the seventh embodiment of this invention. This flowchart shows processing when the video display device 3 is remotely controlled from the terminal device 1.

  Steps S1301 to S1302 are the same as steps S401 to S402 in FIG.

  In step S1311, the terminal device 1 confirms whether or not the emergency bulletin has been received. When the emergency bulletin is received, the terminal device 1 switches to the emergency mode. The emergency warning is information distributed to notify an emergency such as the occurrence of a disaster, such as an emergency earthquake warning or a tsunami warning.

  In step S1303, the terminal device 1 confirms whether or not an operation for ending the operation application has been performed by the user. If an operation for ending the operation application is performed, the terminal device 1 ends the process, and if not operated, it is confirmed whether or not the power button of the video display device 3 is pressed (step S1304). When the power button of the video display device 3 displayed on the terminal device 1 is pressed, the video display device 3 performs different processing depending on whether or not the emergency mode is set.

  In step S1313, the terminal device 1 determines whether or not the emergency mode is set. If the terminal device 1 is in the emergency mode, a power command is transmitted to the video display device 3 (step S1314), and the processes from step S1311 are repeated.

  When transmitting a power command, a predetermined emergency code is transmitted. The emergency code may be a unique code that is completely different from the identification code.

  In step S1313, if it is not the emergency mode, the terminal device 1 performs the process of step S1305.

  Steps S1305 to S1306 are the same as steps S405 to S406 in FIG.

  In addition, when transmitting a power supply command, the identification code of the terminal device 1 is also transmitted.

  In step S1304, when the power button of the video display device 3 displayed on the terminal device 1 is not pressed, the terminal device 1 determines whether or not the user has instructed to change settings other than power on / off of the video display device 3. Confirmation is made (step S1307). Setting changes other than power on / off include, for example, channel change, volume setting, image quality adjustment, and the like.

  When the setting change of the video display device 3 is instructed, the terminal device 1 performs different processing depending on whether or not the emergency mode is set.

  In step S1315, in the emergency mode, the terminal device 1 transmits a corresponding command to the video display device 3 (step S1316), and repeats the processes from step S1311.

  Note that an emergency code is also transmitted when the power command is transmitted.

  In step S1315, if it is not the emergency mode, the terminal device 1 performs the process of step S1308.

  Steps S1308 to S1310 are the same as steps S408 to S410 in FIG.

  When various commands such as a power command and a channel change command are transmitted, the identification code of the terminal device 1 is transmitted.

  In this way, the terminal device 1 that has received the emergency bulletin is switched to the emergency mode, and when the command is transmitted to the video display device 3, the emergency code is added instead of the identification code and transmitted. Switch to emergency mode.

  FIG. 14 is a flowchart showing the processing of the video display apparatus according to the seventh embodiment of the present invention. This flowchart shows processing when the video display device 3 is remotely controlled by the terminal device 1.

  Steps S1401 to S1402 are the same as steps S601 to S602 in FIG.

  Next, in step S1428, the video display device 3 confirms whether or not an emergency code has been received. When the emergency code is received, the video display device 3 switches to the emergency mode (step S1429). In the emergency mode, for example, emergency disaster information is displayed on the display screen.

  When the emergency code has not been received, the video display device 3 stores the identification code in the storage unit 36 by using the terminal device 1 that has transmitted the power command as the terminal device A (step S1403).

  Step S1404 is the same as step S604 in FIG.

  Next, in step S1405, the video display device 3 confirms whether the power command has been received again. When the power command is received, the video display device 3 checks whether the emergency mode or the received power command is a command from the terminal device A (step S1406).

  In addition to switching to the emergency mode in step S1429, the video display device 3 also switches to the emergency mode when an emergency code is received in steps S1405, S1408, S1418, and S1422.

  Whether the command is from the terminal device A can be determined by checking whether the identification code when the command is received matches the identification code stored in the storage unit 36.

  If the emergency mode or the received power command is a command from the terminal device A in step S1406, the video display device 3 turns off the power (step S1407).

  In the present embodiment, toggle control is described as an example in which the video display device 3 repeats power on / off every time it receives a power command. However, the power on and power off commands may be separated.

  If no power command has been received in step S1405, the video display device 3 checks whether another command has been received (step S1408). When the other command is received, the video display device 3 checks whether the emergency mode or the received command is a command from the terminal device A (step S1409).

  If it is determined in step S1409 that the emergency mode or the received command is a command from the terminal device A, the process proceeds to step S1410. After executing the command as instructed, the process returns to step S1405.

  If the emergency mode or the received command is not a command from the terminal device A in step S1409, the video display device 3 performs the process of step S1411. Step S1411 is the same as step S611 in FIG.

  In step S1406, when the emergency mode or the received command is not a command from the terminal device A, the video display device 3 performs the process of step S1416.

  Steps S1416 to S1417 are the same as steps S616 to S617 in FIG.

  Next, in step S1418, the video display device 3 checks whether a power command has been received. When the power command is received, the video display device 3 confirms whether or not the emergency mode is set (step S1419). In the emergency mode, the video display device 3 turns off the power of the video display device 3 (step S1407).

  If the emergency mode is not set in step S1419, the video display device 3 confirms whether the received command is a command from the terminal device A (step S1420).

  Steps S1420 to S1421 are the same as steps S620 to S621 in FIG.

  If the power command is not received in step S1418, the video display device 3 checks whether another command is received (step S1422).

  If another command is received in step S1422, the video display device 3 checks whether the received command is a command from the terminal device A (step S1423).

  If the received command is a command from the terminal device A in step S1423, the video display device 3 executes the command as instructed on the screen A (step S1424). If the received command is not a command from the terminal device A, that is, a command from the terminal device B, the video display device 3 executes the command as instructed on the screen B (step S1425).

  Next, in step S1426, the video display device 3 confirms whether or not the emergency mode is set. In the emergency mode, the video display device 3 executes the command as instructed (step S1427), and repeats the processes from step S1404. When not in the emergency mode, the video display device 3 repeats the processes from step S1418.

  In step S1404, the video display device 3 switches the 2-screen display to the 1-screen display. In step S1423, if the received command is a command from terminal device A, screen A is displayed, and if it is not a command from terminal device A, screen B is displayed. If the video display device 3 has not received any other command in step S1422, the video display device 3 repeats the processes from step S1418.

  Thus, for example, when a power command is sent from the first terminal device 1 to the video display device 3, the video display device 3 is turned on, and the operation can be performed only from the first terminal device 1.

  Next, when the power command is sent from the first terminal device 1 to the video display device 3, the power of the video display device 3 is turned off, but the power command is sent from the second terminal device 1 instead of from the first terminal device 1. When sent, the video display device 3 becomes a two-screen display, and the operation of the original screen can be performed only from the first terminal device 1, and the operation of the added screen can be performed only from the second terminal device 1.

  Then, when the emergency bulletin is received, the video display device 3 returns to the one-screen display, and the operation can be performed from all the terminal devices 1.

  In addition, although the emergency earthquake bulletin and the tsunami warning were taken as examples of the emergency bulletin, the emergency lightning bulletin, the emergency fire bulletin, the emergency typhoon bulletin, the emergency heavy rain bulletin, the emergency river flood bulletin, the emergency eruption bulletin, etc. may be used.

  With the above configuration, the seventh embodiment of the present invention can achieve the same effects as those of the first embodiment.

  Furthermore, when the emergency bulletin is received, if the video display device is displaying two screens, the screen is switched to the single screen display, and the video display devices 3 can be operated from all the terminal devices 1.

  In the above-described embodiment, an example in which a command is sent from the two terminal devices 1 to the video display device 3 and a screen corresponding to each terminal device 1 among the two divided screens is operated. The screen divided into three from the three terminal devices 1 may be operated, and the screen may be divided by the amount of the terminal device 1.
