The information stored in the memory means 213 is then transmitted to the control means 205 via the reverse and displayed on the display means 209.

  At this time, when the remote controller 201 becomes unable to obtain information via the Internet 203 due to a problem with the Internet 203, the display means 209 displays “not connected to the center” shown in the display means 302 of FIG. Please check the connection. ”Display the text and picture to inform the user.

  In practice, communication between the remote controller 201, the Internet 203, and the information supply means 204 follows a procedure such as TCP / IP, but is not described above.

  Next, the operation for setting the presence / absence of network connection will be described with reference to FIGS. 2, 5, and 6. FIG. FIG. 2 shows a configuration diagram, FIG. 5 shows an example of a screen displayed on the display means, and FIG. 6 shows a flowchart.

  When the remote controller 301 is used while connected to the Internet, the “connected” icon on the screen 309 shown in FIG. 5 is selected. Since this state is stored in the network connection presence / absence storage unit 214 in FIG. 2, it functions without problems when the Internet environment is operating correctly.

  If the remote control 301 cannot be connected to the information supply means due to a problem in the Internet environment or the like, the screen displayed on the display means 302 in FIG. 4 informs that the information supply means (center) cannot be connected. At this time, sound may be used for notification.

  If there is a problem with the Internet environment temporarily, it is sufficient to wait for the Internet environment to recover. However, the information supply means has been changed because the Internet contract with the Internet provider has been canceled or the Internet provider that cannot be connected to the information supply means has been changed. If the information supply means cannot be permanently connected to the information supply means via the Internet, such as when the connection with the user cannot be established, the screen displayed on the display means 302 in FIG. 4 is displayed constantly or periodically. Are very inconvenient and annoying.

  In order to avoid this, as shown in the screen 310 of FIG. 5, if the “no connection” icon is selected, even if the Internet and the information supply means cannot be permanently connected for some reason, the display of FIG. Since the screen displayed on the means 302 is not displayed, there is no inconvenience and troublesomeness for the user.

  Here, if the “no connection” icon shown in the screen 310 of FIG. 5 is selected, once selected, even if the network is opened, the Internet and the information supply means cannot be connected. It is necessary to carefully check whether the setting is “None”. Therefore, at this time, the screen 311 of FIG. 5 is displayed, and confirmation of setting to “no connection” is performed again. Of course, there is also a “Cancel” icon for the wrong setting.

  In addition, after selecting the “Continue” icon on the screen 311, it is necessary to take a complicated procedure such as restarting the remote control and changing the setting in the remote control to “no connection”. Since it is memorize | stored in the network connection no construction procedure storage means of 2, it should just progress according to this. Thus, the setting procedure is completed by storing in the network connection presence / absence storage unit 214 in FIG. 2 that the remote controller is not connected to the Internet.

  On the contrary, when the state of “not set” is stored in the network connection presence / absence storage unit 214 in FIG. 2, a situation where the state is changed from “not set” to “set” is also assumed. For example, when resuming an Internet contract with an Internet provider.

  In this case, when the “connected” icon displayed on the screen 309 in FIG. 5 is selected, connection to the Internet is made. However, in this case, in order to store the state of connection to the Internet in the network connection presence / absence storage unit 214 in FIG. 2, the remote control is restarted once and a non-specialist user such as the Internet IP address or gateway is used. It is necessary to make settings related to the Internet, which are extremely difficult, and the user needs to perform complicated procedures for changing the program settings in the remote control, such as restarting again. 2 is stored in the procedure storage means 215 when the network connection is valid in FIG. 2, and the user may set according to this.
