The steps from step S605 are repeated. Upon receiving this status, the terminal device 1 displays on the display unit 22 that it does not have the authority to execute the command. FIG. 5D is an example of displaying that there is no right to change the channel.

  When sending the status information to the terminal device 1, the video display device 3 may send the identification code used when the command is received in step S608 together with the status information. As a result, 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 process from step S605.

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

  Next, in step 617, the video display device 3 displays two screens, 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 checks again whether the power command has been received. When receiving the power command, the video display device 3 confirms whether the received command is the command from the terminal device A (step S620).

  If the received command is the command from the terminal device A in step S620, the video display device 3 stores the identification code of the terminal device 1 stored in the storage unit 36 as the terminal device B as the terminal device A. (Step S621), the process from step S604 is repeated.

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

  In step S620, when the received command is not the command from the terminal device A, 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 supply command is not received in step S618, the video display device 3 confirms whether or not another command is received (step S622).

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

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

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

  The command executed on the screen B is, for example, a setting command for instructing to change the channel of the screen B or switch the input. The setting change common to the screen A and the screen B, such as the volume and the brightness, may be executed by the terminal device B or may not be executed by the terminal device B.

  If no other command is received in step S622, the video display device 3 repeats the process from step S618.

  In this way, for example, when a 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 on, and the operation can be performed only from the first terminal device 1.

  Next, when a 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 a 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 changing the channel 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.

Then, when a power command is sent from the second terminal device 1 to the video display device 3, the power of 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. 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.

  That is, if a power command is sent from the terminal device 1 itself 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 original screen can be operated only from the original terminal device 1, and the added screen can be operated only from another terminal device 1.

  Then, when a power command is sent from one of the terminal devices 1 during the two-screen display, the video display device 3 switches to the one-screen display, and only from the terminal device 1 different from the terminal device 1 which 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 by the terminal device 1 to the video display device 3 are stored, and after the power command is transmitted, the stored setting values are displayed. By transmitting to the display device 3, the user simply turns on the power using the terminal device 1, and the video display device 3 is set to the channel or volume that was watched last time.

  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 own terminal devices 1, and the video display device 3 can be stored using their own terminal device 1. When the power is turned on, the video display device 3 can be set to the setting last viewed by the user. Furthermore, the setting that is being viewed on one video display device 3 can be reflected on another video display device 3.

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

  Then, when a power supply command is sent to the video display device 3 in which the screen is split and displayed, the split display of the screen of the video display device can be ended.

  Thus, for example, when a 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 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 becomes a two-screen display, and the channel switching of the original screen is performed only from the first terminal device 1 by the channel of the added screen. 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.

  Furthermore, 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 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 single screen display, and the operation can be performed only from the terminal device 1. 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.

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

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

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

  Next, a fourth embodiment of the present invention will be described. The configuration, effects, and the like in this embodiment are the same as those in the first embodiment unless otherwise specified. Therefore, differences between this 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 a process when the video display device 3 is remotely controlled by the terminal device 1.

  Steps S901 to S905 are similar to steps S601 to S605 in FIG.

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

  When the two-screen switching command is received in step S913, the video display device 3 confirms whether the received command is the command from the terminal device A (step S914).

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

  In the present embodiment, toggle control is shown as an example in which the image display device 3 switches between two-screen display and one-screen display each time it receives a two-screen switching command. Commands may be separated.

  When the received command is not the 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 similar to steps S616 to S617 in FIG.

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

  The other commands are, for example, setting commands for instructing switching of channels and setting of volume or brightness.

  In step S908, when the other command is received, the video display device 3 performs the process of step S909, and 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. 6, and thus description thereof will be omitted.

  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.

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

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

  When the two-screen switching command is received in step S919, the video display device 3 confirms whether it is the command from the terminal device A (step S920).

  When the two-screen switching command has not been received in step S919, the video display device 3 confirms whether or not a command other than the power supply command and the two-screen switching command has been received (step S922).

  Steps S920 to S925 are similar to steps S620 to S625 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 power of the video display device 3 is turned on, and the operation can be performed only from the first terminal device 1.

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

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

  Then, 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 same effect as that of the first embodiment can be obtained in the fourth embodiment of the present invention.

  Furthermore, when a two-screen switching command is sent from a terminal device 1 other than the terminal device 1 that has turned on the power of the video display device 3, the screens of the video display device 3 are divided and displayed, and the screens corresponding to each terminal device 1 Can be operated.

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

  Next, a fifth embodiment of the present invention will be described. The configuration, effects, and the like in this embodiment are the same as those in the first embodiment unless otherwise specified. Therefore, differences between this 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 a process 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. 9, and thus description thereof will be omitted.

  Steps S1008 to S1015 are the same as steps S808 to S815 of FIG. 8, and thus description thereof will be omitted.

  In step S1018, the video display device 3 confirms whether or not the power command is received. When the power command is received, the video display device 3 turns off the power (step S1007).

  In step S1018, when the power supply command has not been received, the video display device 3 confirms whether or not a command for instructing the end of the operation application (hereinafter, “application end command”) has been received (step S1019).

  When the application end command is received in step S1019, the video display device 3 confirms whether or not the command is from the terminal device A (step S1020).

  Since steps S1020 to S1021 are the same as steps S620 to S621 in FIG. 6, description thereof will be omitted.

  When the application end command has not been received in step S1019, the video display device 3 confirms whether or not the channel change command has been received (step S1022).

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

  Thus, for example, when a 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 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 becomes a two-screen display, and the channel switching of the original screen is performed only from the first terminal device 1 by the channel of the added screen. 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.

  Furthermore, 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 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 single-screen display, and the operation can be performed only from the first terminal device 1. 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.

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

  Furthermore, when a channel change command is sent from a terminal device 1 other than the terminal device 1 that has turned on the video display device 3, the screens of the video display device 3 are divided and displayed, and the corresponding screens are displayed from each terminal device 1. It can be operated.

  Then, when an application end command is sent to the video display device 3 in 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. The configuration, effects, and the like in this embodiment are the same as those in the first embodiment unless otherwise specified. Therefore, differences between this embodiment and the first embodiment will be mainly described below.

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

  Steps S1101 to S1118 are similar to steps S1001 to S1018 in FIG.

  When the power supply command is not received in step S1118, the video display device 3 confirms whether or not the channel change command is received (step S1122).

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

  When the received command is the 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.

  When the received command is not the 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 is not received in step S1122, the video display device 3 performs the process of step S1126.

  Since steps S1126 to S1127 are the same as steps S826 to S827 in FIG. 8, description thereof will be omitted.

  Next, in step S1128, the video display device 3 confirms whether the changed channel of the screen A and the changed channel of the screen B match.

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

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

  In this way, for example, when a 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 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, the original screen operation is performed only from the first terminal device 1, and the added screen operation is performed at the first screen. It can be performed 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.

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

  With the above configuration, the sixth embodiment of the present invention can obtain the same effect as that of the first embodiment.

  Furthermore, when a channel operation command is sent from a terminal device 1 other than the terminal device 1 that has turned on the video display device 3, the screens of the video display device 3 are divided and displayed, and the corresponding screens are displayed from each terminal device 1. It can be operated.

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

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

  FIG. 13 is a flowchart showing the processing of the terminal device 1 according to the seventh embodiment of the present invention. This flowchart shows a process 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. 4, and thus description thereof will be omitted.

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

  In step S1303, the terminal device 1 confirms whether or not the user has performed an operation for ending the operation application. When the operation for ending the operation application is performed, the terminal device 1 ends the process, and when not operated, the terminal device 1 confirms 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 it is the emergency mode.

  In step S1313, the terminal device 1 determines whether or not it is in the emergency mode, and when it is in the emergency mode, transmits a power command to the video display device 3 (step S1314), and repeats the process from step S1311.

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

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

  Since steps S1305 to S1306 are the same as steps S405 to S406 in FIG. 4, description thereof will be omitted.

  When transmitting the power command, the identification code of the terminal device 1 is also transmitted.

  Further, 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 the setting change other than the power on/off of the video display device 3. Confirm (step S1307). The setting change other than power on/off is, for example, channel change, volume setting, image quality adjustment, or the like.

  When the setting change of the video display device 3 is instructed, the terminal device 1 performs different processing depending on whether it is the emergency mode.

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

  An emergency code is also transmitted when transmitting the power command.

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

  Since steps S1308 to S1310 are the same as steps S408 to S410 in FIG. 4, description thereof will be omitted.

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

  In this way, the terminal device 1 that has received the emergency bulletin switches to the emergency mode, and when transmitting the command 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 device according to the seventh embodiment of the present invention. This flowchart shows a process 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. 6, and thus description thereof will be omitted.

  Next, in step S1428, the video display device 3 confirms whether or not the emergency code is 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 is not received, the video display device 3 stores the identification code in the storage unit 36, with the terminal device 1 that has transmitted the power command as the terminal device A (step S1403).

  Since step S1404 is the same as step S604 in FIG. 6, description thereof will be omitted.

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

  The video display device 3 switches to the emergency mode in step S1429 described above, and also switches to the emergency mode in step S1405, step S1408, step S1418, and step S1422 when an emergency code is received.

  Whether or not the command is from the terminal device A can be determined by whether or not the identification code when the command is received matches the identification code stored in the storage unit 36.

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

  In the present embodiment, the toggle control in which the power supply command is repeated every time the video display device 3 receives the power supply command is shown as an example, but the power supply on and power off commands may be separated.

  If the power command is not received in step S1405, the video display device 3 confirms whether or not another command is received (step S1408). When the other command is received, the video display device 3 confirms whether the emergency mode or the received command is the command from the terminal device A (step S1409).

  In step S1409, when the emergency mode or the received command is the command from the terminal device A, the process proceeds to step S1410, the command is executed as instructed, and the process returns to step S1405.

  Further, in step S1409, when the emergency mode or the received command is not the command from the terminal device A, the video display device 3 performs the process of step S1411. Since step S1411 is similar to step S611 of FIG. 6, description thereof will be omitted.

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

  Steps S1416 to S1417 are similar to steps S616 to S617 in FIG.

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

  In step S1419, when it is not the emergency mode, 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. 6, and thus description thereof will be omitted.

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

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

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

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

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

  In this way, for example, when a 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 on, and the operation can be performed only from the first terminal device 1.

  Next, when a 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 a 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 original screen can be operated only from the first terminal device 1, and the added screen can be operated 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.

  Although the earthquake early warning and the tsunami warning are taken as examples of the emergency early warning, it may be emergency lightning early warning, emergency fire early warning, emergency typhoon early warning, emergency heavy rain early warning, emergency river flood early warning, emergency eruption early warning, and the like.

  With the above configuration, in the seventh embodiment of the present invention, the same effect as in the first embodiment can be obtained.

  Further, at the time of receiving the emergency bulletin, if the video display device is displaying two screens, it is switched to one screen display, and all the terminal devices 1 can operate the video display device 3.

  In the above-described embodiment, an example is shown 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 is operated from among the two screens divided. A screen divided into three from the three terminal devices 1 may be operated, or the screen may be divided according to the number of the terminal devices 1.
