  FIG. 2 is an example of a display screen showing a list to be displayed when using skype. The list shown in the figure is called when a user makes a call using the skype function, and is a list of sky users (users in an environment that can use the skype).

  A skype user name (Name1, Name2, Name3, etc.) is displayed in the list frame 10 of the displayed list, and a message 20 from the individual is displayed to the right of the user name. In addition, scroll direction marks that can be scrolled up, down, left, and right are provided at positions around the list frame 10. When there are many sky users, the list frame 10 cannot be entered, and the user is hidden downward. Further, when the message 20 has a large number of characters, the message 20 does not fit in the list frame 10 and is partially hidden in the right direction. As described above, when the user cannot fit in the list frame 10, the user scrolls the scroll direction mark to see the hidden portion.

  According to the present embodiment, if the notation of the item displayed in the list frame 10 is long, it is hidden because it does not fit in the list frame 10, and the continuation can be seen by scrolling to the right. Therefore, the right scroll direction mark 40 is blinked to notify the user that there is a continuation and to inform the scroll direction. When scrolling in the right direction, the scroll direction mark 50 indicating the left direction is also blinked to notify that there is a notation hidden in the left direction.

  Furthermore, if the number of lists (the number of sky users) increases, it will not fit in the list frame 10, so the downward scroll direction mark 30 blinks, and this blinking informs that there is a list hidden downward. Inform them that they can scroll at the same time. When scrolling downward, the scroll direction mark 60 indicating the upward direction is also blinked to notify that there is a list hidden in the upward direction and that scrolling is possible.

  That is, by blinking the scroll direction mark itself, it is possible to inform the user in which direction there are hidden items, or to inform the user of the valid direction keys of the remote controller 120.

  Although the scroll direction mark is blinked here, for example, it may be turned on, the scroll direction mark may be colored, or the scroll direction mark itself may be enlarged. In addition, a means for notifying the user by pop-up display or a message board instead of the scroll direction mark may be taken.

FIG. 3 is a flowchart for displaying the list display of FIG.
First, when a user presses an IP phone button (not shown) using the remote controller 120 to start a call using the IP phone “skype”, a command is notified to the CPU 252 via the operation input unit 253. Upon receiving this command, the CPU 252 reads a list of sky users from the flash memory 261 stored in advance, and controls the GUI control unit 254 to display the list on the display 224.

  When the list is displayed on the display 224 (step S1), the CPU 252 checks whether there is a hidden display in one record of the list (step S2). If there is no hidden display (N in Step 2), the CPU 252 controls not to blink the scroll direction mark indicating the right direction (Step S3). When there is a hidden display (Y in step 2), the CPU 252 controls the GUI control unit 254 to display a scroll direction mark 40 indicating the right direction in order to indicate that there is a hidden display in the right direction within one record. A blinking display is made (step S4).

  This time, the CPU 252 checks whether or not there is a list hidden in the downward direction (step S5). If there is no hidden display (N in step S5), similarly to step 3, control is performed so that the scroll direction mark 30 indicating the downward direction does not blink (step S6). If there is a hidden display (Y in Step 5), the CPU 252 controls the GUI control unit 254 to display the scroll direction mark 30 indicating the downward direction in a blinking manner in order to indicate that there is a hidden display in the downward direction ( Step S7).

  When the user scrolls the scroll direction mark 40 indicating the right direction that is blinking (step S8), a display hidden in the left-right direction in one record of the list may appear. The CPU 252 confirms whether or not there is a hidden display in the left and right direction in this one record (step S9), and if it is determined that there is still a hidden display in the right direction, the scroll direction mark 40 is flashed and displayed (step S10). When it is determined that there is a display hidden in the left direction (if the scrolling is performed in the right direction, the left direction is hidden), the scroll direction mark 50 is displayed blinking (step S11).

  Next, when the user scrolls the scroll direction mark 30 indicating the downward direction that is blinking (step S12), a list hidden in the vertical direction may appear. The CPU 252 checks whether or not there is a list hidden in the vertical direction (step S13), and if it is determined that there is a list still hidden in the downward direction, the scroll direction mark 30 blinks (step S14). If it is determined that there is a list hidden in the upward direction (upward notation is hidden when scrolling downward), the scroll direction mark 60 is displayed blinking (step S15).

  As described above, according to the embodiment, the scroll direction mark blinks to notify the user which item is hidden in which direction, which direction key of the remote control is currently active, It is possible to inform the consent which direction key can be pressed to scroll in which direction.
