  The first conventional technique described above is a technique for displaying in order from the user with the highest degree of interest based on the display instruction / display time by the user. However, this conventional technique has a problem that only simple control for increasing priority based on user operation can be performed, and fine control based on, for example, a display location cannot be performed.

  The second prior art described above can also perform only simple control of controlling (displaying longer) the display time during fast-forward playback based on user evaluation (display count). For example, the display order is changed. Such a fine control cannot be performed.

  Furthermore, in the prior art, even when an action from the user (reference) is possible for the display content (for example, displaying more detailed information by touching the screen, etc.), the action from the user is fed back to the content display schedule. I couldn't. For this reason, there has been a problem that the intention of the content provider cannot be quickly reflected in the scheduling.

  In view of this, the disclosed technique aims to make it possible to reflect user actions and usage environments in scheduling of content display.

An example of the mode is based on a content display method that displays content based on a preset schedule.
In the display device that displays the content, the following process is executed.

  Next, when an action occurs, the current state information in the target data set of the held schedule information corresponding to the content displayed when the action occurs is updated.

Next, the current state information updated in the target data set is compared with the state threshold information in the current data set.
Based on the comparison result, the operation corresponding to the operation type information in the target data set is executed on the content corresponding to the content identification display information in the target data set.

In another example of the aspect, in addition to the above-described process, the following process is further performed.
First, based on the comparison result, information related to the target data set of the schedule information is notified to the display device management server.

In the display device management server, installation information defining a group of display devices to be operated in synchronization is held.
Next, in the display device management server, the group to which the display device that has notified the information related to the target data set of the schedule information belongs is searched from the installation information, and the target data set of the schedule information notified to each display device belonging to the group is retrieved. Information about is notified.

  On the other hand, in each display device belonging to the group, the schedule information held by the own device is updated based on the information on the target data set of the schedule information notified from the display device management server.

  Based on the updated schedule information, the operation corresponding to the operation type information in the target data set is synchronized with other display devices for the content corresponding to the content identification display information in the target data set. Executed.

In the display device, the display state of the screen content can be controlled based on the action by the user.
Further, it is possible to control the display state of the display content of the plurality of display devices in synchronization with each other based on the action by the user on one display device.

This control operation is performed not only when the schedule information data set is transmitted from the display device management server 102 by the synchronization processing in step S704 of FIG. 7 described above, but also when the display device 101 starts operation. This includes the case where all data sets constituting the schedule information stored in the schedule information storage unit 203 for the display device 101 are transmitted in a batch.

First, a data set of schedule information is received from the display device management server 102 (step S801).
Next, the corresponding data set in the schedule information stored in the schedule information storage unit 203 is rewritten by the data set of the schedule information received in step S801 (step S802).

Thereafter, the control operation shown in the operation flowchart of FIG.
Through the series of control operations described above, in the present embodiment, in each display device 101, for example, when the action by the touch operation on the display screen or the like by the user exceeds a predetermined number of times, the point in time when the touch operation is performed is performed. It is possible to execute control to hide the screen content.

  For example, in the operation example of FIG. 9A, for each screen content of the screen 1, the screen 2, and the screen 3, the schedule information data set stored in the schedule information storage unit 203 corresponding to “4. Since the “number of actions” (see FIG. 3A) is “0”, each of the screen contents 1 to 3 is “2” of the schedule information data set stored in the corresponding schedule information storage unit 203. .. Display interval ”=“ 1 minute ”is repeatedly displayed.

  For example, when the information on the screen 3 of the data set of the schedule information stored in the schedule information storage unit 203 is “6. Action action type” = “Hidden”, it is determined by the user when the screen 3 is displayed. When the touch operation reaches 50 times, as shown in FIG. 9B, the screen 3 is not displayed by the control operation that transitions from step S602 to step S604 in FIG. 6, and only the screen contents 1 and 2 are displayed. Are repeatedly displayed at a display time of “2. Display interval” = “1 minute” of the schedule information data set stored in the corresponding schedule information storage unit 203.

  As another embodiment, in each display device 101, for example, when the action by the touch operation on the display screen or the like by the user exceeds a predetermined number of times, the screen content at the time when the touch operation is performed is given priority. It is also possible to execute control such as displaying or lengthening or shortening the display time.

  Furthermore, in this embodiment, when the display state of a certain display content changes based on the user's action in one display device 101, the display device 101 has a schedule corresponding to the display content that has changed. The data set of schedule information stored in the information storage unit 203 is transmitted to the display device management server 102. Based on the installation information stored in the installation information storage unit 207, the display device management server 102 sets the schedule information stored in the schedule information storage unit 203 to the display devices 101 synchronized with each other. Send. Thereby, based on the action by the user in one display device 101, it becomes possible to control the display state of the display content of the plurality of display devices 101 in synchronization.
