  However, in the information transmission system as described above, when a part of a plurality of display screens (display terminals) breaks down, it is usually set so that only specific information is displayed on the display screen. Information cannot be displayed. In this case, there is a problem that information necessary for the user such as train departure time information and operation information is not displayed even though the other display screens are blank and empty. In addition, as shown in FIG. 18, even if it is normal time, if the display of important information (notice) or the like is secured as a dedicated area, the display screen of the dedicated area is blank when there is no important information. There is a problem that the display screen is not effectively used.

  An object of the present invention is to automatically perform a substitute display on the remaining display screen when a failure occurs in one display screen when there are a plurality of display terminals and display screens (display areas) in one area. To do. In addition, the information display system is intended to efficiently use all display screens.

  To achieve the above object, the present invention provides an information display system that distributes content information, schedule information, and group information of display terminals from a distribution server to a plurality of display terminals via a network.

FIG. 1 shows a system block diagram of the present invention. The information display system according to the present invention includes a distribution server 100 that is a provider that provides various information distribution services, and a plurality of display terminals 111-installed in a facility that displays information at a window or public facility such as a bank or securities. A, 111-B, 211-A, 211-B, 311-A, 311-B, 311-C and fault detection function 112-A, 112-B, 212-A, 212-B, 312-A, 312 -B and 312-C are connected to the respective display devices 110, 210, and 310 via the Internet 120, and the distribution server 100 is supplied by an external information provider such as a facility provider or a news provider. The acquired content data storage unit 101, group data storage unit 102, display terminal data storage unit 103, and display terminal state data storage unit 104 are included.

  The function of the distribution server 100 will be specifically described. The distribution server 100 has a display terminal registration function, a group registration function, a content registration function, a schedule registration function, a data distribution function, and a display terminal monitoring function, each of which will be described in detail. First, the distribution server 100 has a display terminal registration function for registering the display terminals 111-A, 111-B, 211-A, 211-B, 311-A, 311-B, 311-C. Specifically, as shown in FIG. 2, this is a function for registering on which display terminal to display each content as a distribution destination, and the display terminal name and the number of screens are registered in the display terminal data storage unit 103. The group ID is updated at the time of group registration described later.

  Next, the distribution server 100 has a group registration function, which is a function for registering a plurality of display terminals that link display contents as a group. Specifically, as shown in FIG. 3A, a group is created by giving a group name and a group ID, and a plurality of display terminals and the number of screens are registered in the group data storage unit 102 for each created group. Also, as shown in FIG. 3B, a display position ID is assigned to each screen of a plurality of display terminals in the same registered group and registered in the group data storage unit 102. The display position ID is used when designating a screen to be displayed in content registration. Thereby, the display terminal and screen which should be displayed can be decided. In addition, the state (normal or not) of each screen of a plurality of display terminals detected by the display terminal monitoring function described later can also be registered.

  Next, the distribution server 100 has a content registration function, which is a function of registering the content in the content data storage unit 101 with a priority order to be displayed on the content itself. Specifically, as shown in FIG. 4, when a distribution content list is created, priority is given to each content based on this distribution content list, and a plurality of contents are requested to be displayed on the same screen. Is a function for controlling display using the priority order of the contents registered in advance.

  Next, the distribution server 100 has a schedule registration function, which is a function for registering the schedule of the display terminal for each group. Specifically, as shown in FIG. 5, the display time (start to end) and the priority display position are set and registered in the group data storage unit 102 for the content to be displayed. Basically, the image is displayed at the priority display position 1 shown in FIG. 5, but when a failure occurs on the screen of the priority display position 1, it can be controlled to display at the next priority display position 2.

  Next, the distribution server 100 has a data distribution function, and the registered display terminals 111-A, 111-B, 211-A, 211-B, 311-A, 311-B, 311-C, This function distributes group information, display screen information, schedule information, and content information for each group via the Internet 120.

  Next, the distribution server 100 has a display terminal monitoring function, and the display terminals 111-A, 111-B, 211-A, 211-B, 311-A, 311-B, 311-C operate normally. It is a function to monitor whether or not. When a failure occurs in the display terminal, the state of the display terminal is registered in the display terminal state data storage unit 104 and is reflected in the management table for each group.

  Next, functions of the display devices 110, 210, and 310 will be specifically described. The display device 110 includes a plurality of display terminals 111-A and 111-B and a plurality of failure detection units 112-A and 112-B. The display terminals 111-A and 111-B include a content reception accumulation display function and a group. Since it has a cooperation function with other display terminals, the failure detection units 112-A and 112-B have a display terminal failure detection function, details will be described respectively. The display terminals 111-A and 111-B receive data such as group information, display screen information, schedule information, and content information from the distribution server 100, accumulate the received information, and according to the group information and schedule information, There is a content reception accumulation display function for content display / playback. With the content reception accumulation display function of the display terminals 111-A and 111-B, various data can be received from the distribution server 100, and the data can be accumulated and stored. Further, the content can be displayed on a predetermined screen at a predetermined time based on the received data. The content reception accumulation display function of the display devices 210 and 310 is the same as that of the display device 110.

  Next, the failure detection units 112-A and 112-B have a display terminal failure detection function. When it is detected that an abnormality has occurred in display or playback, the playback is stopped, and this is indicated in the group. This is a function of contacting the display terminals 111-A and 111-B. The communication route may define a master display terminal in the group, collect information once in the master display terminal, and then notify the display terminals 111-A and 111-B in other groups. After collecting information in a distribution device (not shown), the distribution device may notify the display terminals 111-A and 111-B. Further, when an abnormality is detected in the display terminals 111-A and 111-B, the information is also distributed to the display terminal state data storage unit 104 of the distribution server 100 via the Internet 120, and the management data for each group is displayed. Reflected.

  Here, although there are various failure detection methods for the display terminal failure detection function, three typical methods will be described. The first failure detection method is a self-diagnosis method. In the self-diagnosis method, the display terminal itself always monitors the display / playback program, and stops playback when an abnormality occurs. As a determination method of failure detection, an image may be monitored with an optical sensor, or in the case of an image including sound, the sound may be detected and an abnormality may be determined when the sound is interrupted for a long time. That is, the display terminal failure detection function itself of the display terminals 111-A and 111-B is a method of automatically detecting a failure according to a preset criterion.

  The second failure detection method is a method for manually inputting failure information. The failure information manual input method is a method in which failure information is manually input when a person notices that there is a failure in display or sound. Specifically, when a failure is confirmed on the display screen, a person inputs failure information at an input unit (not shown) connected to the display terminals 111-A and 111-B, and the failure detection is performed by the display terminal failure detection function. Information is registered.

  The third failure detection method is a network monitoring method. The network monitoring method periodically checks whether or not the display terminals 111-A and 111-B are operating via the network, and determines that the display device 110 has completely stopped if there is no response. It is a method to do. As a monitoring method in the network, the display terminals 111-A and 111-B in the group may mutually perform, or a master display terminal may be defined and the master display terminal may monitor the group. Further, a distribution device (not shown) may monitor all display terminals. The display terminal failure detection function of the display devices 210 and 310 is the same as that of the display device 110.

  Furthermore, the display terminals 111-A and 111-B have a cooperation function with other display terminals in the group, and display results of failure detection are used as display terminal state data to display the display terminals 111-A and 111-B in the group. Each display terminal 111-A and 111-B can display appropriate content according to the state of failure. With this function, when a failure occurs on one display screen, it can be displayed instead of the display screen on which no failure has occurred. The cooperation function with other display terminals in the group of the display devices 210 and 310 is the same as that of the display device 110.

  Next, a display position determination procedure when displaying content will be described. Originally, when a failure occurs on the display screen to be displayed, the content is arranged in the following procedure. When the display terminal itself determines, as shown in FIG. 5, the display position of the content is determined according to the order of the priority display positions 1 to 4 registered in the schedule distributed from the distribution server 100. Specifically, first, when the state of the display position of the priority display position 1 is normal, the content is arranged at the display position of the priority display position 1. On the other hand, when the state of the priority display position 1 is abnormal, it is checked whether the state of the display position is normal in the order of the priority display positions 2, 3, and 4, and is first arranged at the display position where the state is normal. Here, when another content has already been arranged at the display position to be displayed, the arrangement method is changed depending on the case. First, the distribution content list shown in FIG. 4 is confirmed, and if the priority of the content to be arranged is lower than the contents already arranged, the contents cannot be arranged. That is, the already arranged content is displayed. When the priority order of the contents to be arranged is the same as the contents already arranged, both of them can be arranged alternately. When the priority of the content to be arranged is higher than the contents already arranged, the already arranged contents can be deleted and new contents can be arranged. In addition to determining the display position of the content according to the order of the priority display positions 1 to 4 registered in the schedule, as shown in FIG. 6, the display position ID of its own screen is acquired from the group information, The content arranged at the display position ID may be displayed. Alternatively, a method may be used in which a master display terminal is defined within a group, the arrangement is determined by the master display terminal, and each display terminal is notified. At this time, a method of determining the arrangement by a distribution device (not shown) and notifying the display position of each display terminal may be used.

  Next, an operation example when performing content display of the present invention will be described. First, group registration of a plurality of display terminals will be described. As shown in FIG. 7, the display device 110 registers, for example, the display terminal 111 -A and the display terminal 111 -B, and subsequently registers these display terminals 111 -A and 111 -B as a group and displays each display terminal 111. A display position number (display position ID1 to display position ID4) is assigned to the display screens (screen 1 to screen 2) of -A, 111-B, for example, the display position ID1 corresponds to the screen 1 of the display terminal 111-A, The display position ID2 corresponds to the screen 1 of the display terminal 111-B, the display position ID3 corresponds to the screen 2 of the display terminal 111-A, and the display position ID4 corresponds to the screen 2 of the display terminal 111-B. This completes group registration and makes it clear which display screen of which display terminal displays the content. Examples of operations when displaying content are mainly classified into three cases: when content displays do not overlap, content displays with different priorities overlap, and content displays with the same priority overlap. Details of each will be described below.

  When the content display does not overlap on the same display screen, a distribution content list as shown in FIG. 8A is distributed from the distribution server 100, and the priority order of the distribution information is set. Further, as shown in FIG. Thus, for example, the schedule of the group 001 is set in advance and distributed from the distribution server 100. In the schedule of FIG. 8-2, since all contents are displayed at the priority display position 1 if they are normal, each content is set on a separate screen. Therefore, since the display of each content is not displayed on the same display position ID (display screen), as shown in FIG. 9, the content required for the display screen determined in the display screen in the registered group Is displayed without excess or deficiency.

  On the other hand, when content displays having different priorities overlap on the same display screen, a distribution content list as shown in FIG. 10A is distributed from the distribution server 100 and the priority order of distribution information is set. As shown in 10-2, for example, a schedule for the group 001 is set in advance and distributed from the distribution server 100. Here, based on the schedule of FIG. 10-2, if it is normal, all are displayed at the priority display position 1. However, when contents are scheduled twice on the same display screen, Based on the distribution content list, content with high priority (low value) is preferentially displayed. That is, in the case of the schedule of FIG. 10-2, “CM etc.” is scheduled independently from 7:00 to 10:00 for the display position ID4, but “Notification” is set at 10:00 to 15:00. ”Is also scheduled, and the content is scheduled twice, so in the time zone from 10:00 to 15:00, a plurality of content display requests of“ CM etc. ”and“ Notification ”are displayed at the same display position ID4. Since this occurs, the display position ID4 in this time zone overlaps. Therefore, in such a case, as shown in FIG. 11A, in the time zone from 10:00 to 15:00, “notice” having a high priority (small value) is displayed instead of “CM”. Is done. When the schedule of each display position ID of the group 001 is represented by a time axis band, as shown in FIG. 11B, the display position ID4 is not “CM etc.” in the time zone from 10:00 to 15:00. The “Notice” content is displayed so as to interrupt.

  Here, when content displays having different priorities overlap on the same display screen, when a failure occurs on the screen 2 of the display terminal 111-A having the display position ID3, that is, the priority display position of the content “operation information” When a failure occurs in the display position ID3 that is 1, the display screen of the content of “operation information” is changed from the display position ID3 that is the priority display position 1 to the priority display position 2 as shown in FIG. It is necessary to move to display position ID4. However, since “CM etc.” is already displayed at the display position ID 4 and a plurality of content display requests of “CM etc.” and “operation information” are generated at the same display position ID 4, two contents are displayed. It will overlap. In this case, content with a high priority (small value) is displayed on the basis of the distribution content list, and therefore, as shown in FIG. “Operation information” with high priority is displayed. If the schedule of each display position ID of the group 001 is represented by a band on the time axis, as shown in FIG. 12B, when a failure occurs at the display position ID3, the display position ID4 is not “CM”. The content of “operation information” is displayed.

  When content displays having the same priority order overlap the same display screen, a distribution content list as shown in FIG. 13A is distributed from the distribution server 100 to set the priority order of the distribution information. As shown in -2, for example, the schedule of the group 001 is set in advance and distributed from the distribution server 100. Here, based on the schedule of FIG. 13-2, if it is normal, all are displayed at the priority display position 1. However, when content is scheduled twice on the same display screen, It is necessary to display contents having the same priority order based on the distribution contents list. That is, in the case of the schedule of FIG. 13-2, “CM etc.” is scheduled independently for display position ID4 from 7:00 to 10:00, but “Notification” is set at 10:00 to 15:00. Is also scheduled, and the content is scheduled twice. As a result, in the time zone from 10:00 to 15:00, a plurality of content display requests “CM etc.” and “Notification” are generated at the same display location ID4, so that the display of the display location ID4 in this time zone overlaps. End up. Therefore, it is determined which one is displayed based on the priority order of the distribution content list of FIG. 13A. However, according to the distribution content list of FIG. When the contents having the same priority are scheduled to be displayed on the same display screen, the contents are alternately displayed. When the schedule of each display position ID of the group 001 is represented by a time axis band, as shown in FIG. 14, “CM etc.” and “Notification” are displayed in the time period from 10:00 to 15:00 at the display position ID4. They are displayed alternately. Depending on the display contents, there are not only a method of alternately displaying but also a method of dividing and displaying the screen at the same time or a method of dividing and displaying the time. In addition, even in the case of alternately displaying, various timings for exchanging the display are conceivable and can be changed at the intention of the user company. In any case, when content with the same priority in the distribution content list is displayed on the same display screen, a display method is devised so that it is displayed evenly.

  Here, when content displays having the same priority order overlap on the same display screen, when a failure occurs on the screen 2 of the display terminal 111-A having the display position ID3, that is, the priority display position of the content “operation information” When a failure occurs in the display position ID3 that is 1, it is necessary to move the display screen of the content of “operation information” to the display position ID4 that is the priority display position 2, as shown in FIG. However, since “notification” has already been displayed at the display position ID4, and a plurality of content display requests for “notification” and “operation information” are generated, the display of two contents overlaps at the same display position ID4. End up. In this case, the priority order of the contents is confirmed based on the distribution contents list shown in FIG. 15A. However, since the priority order of “notice” and “operation information” is the same, both are displayed on the same display screen. There is a need. Therefore, when the schedule of each display position ID of the group 001 is represented by a time axis band, as shown in FIG. 16, when a failure occurs at the display position ID3, “notification” and “operation” are displayed at the display position ID4. The content of “information” is displayed alternately. Depending on the display contents, there are not only a method of alternately displaying but also a method of dividing and displaying the screen at the same time or a method of dividing and displaying the time. In addition, even in the case of alternately displaying, various timings for exchanging the display are conceivable and can be changed at the intention of the user company. In any case, when content with the same priority in the distribution content list is displayed on the same display screen, a display method is devised so that it is displayed evenly.

  The overall flow of the above operation example will be described with reference to the flowchart of FIG. First, when an event such as a failure or a display change request occurs, a) content placement processing is started in order to rearrange the content. a) When the content placement process is started, if it is desired to change the schedule, b) the contents of the schedule to be changed are extracted by extracting one line of data to be changed from the schedule. Next, c) Confirm the display of the start time and the end time according to the content display time in the changed schedule by the display time check, and determine whether it is within the display time or outside the display time.

  c) If the result of the display time check indicates that it is within the display time, for example, in order to confirm a change in the state of the display device 110, the process proceeds to d) a state check of the display position n. On the other hand, if it is outside the display time, it is not necessary to d) check the state of the display position n, e) check the position of the display position, and f) compare the priority order of the contents. If it is within the display time, d) check the state of the display position n in order to confirm the state change of the display device 110, and determine whether it is normal or abnormal. If it is normal, e) proceed to display position arrangement check. On the other hand, if there is a failure, g) compare the number of screens in the group with the number of display positions n, and schedule if the number of display screens in the group is greater than or equal to the number of display positions n. Changes can be made. On the other hand, if the number of screens in the group is smaller than the number of display positions n, d) the state of the display position n is checked again.

  d) If the status check of the display position is normal, e) check the arrangement of the display position n, and determine whether it has been arranged or not arranged. If the content has already been arranged, f) the priority order of the content to be arranged and the arranged content is compared. On the other hand, if it is not arranged, new contents are arranged, and h) the schedule is changed and the process is terminated. If it has already been placed, f) Compare the priority of the content to be placed with the placed content, and if the priority of the content to be placed is high, replace the placed content with new content and try to place it. If the priority order of the content to be set and the arranged content is the same, new content is additionally arranged. On the other hand, if the priority of the content to be arranged is low, g) compare the number of screens in the group with the number of display positions n, and the number of display screens in the group is greater than the number of display positions n or In the case of the same number, the schedule can be changed. On the other hand, if the number of screens in the group is smaller than the number of display positions n, d) the state of the display position n is checked again. Through the above flow, the content display schedule according to the present invention can be changed.

  As described above, the present invention relates to a display system that performs display based on content information and schedule information distributed from a distribution server when there are a plurality of display terminals and display screens (display areas) in one area. It is an invention, and by giving a display priority to content information to be displayed in advance, when a failure occurs in one display screen, an alternative display can be automatically performed on another display screen. is there.
