In addition to the preparatory process), the preparatory process in the second stage (ie, the preparatory process of “progress level 2”) is completed. In this case, the display processing terminal 20 can display the display content on the display device 40 only by performing the third stage preparation process and the final process (that is, in a short time).

When the event occurrence probability is equal to or higher than a predetermined third threshold (for example, 85%), the display processing terminal 20 performs the third stage preparation process in addition to the first stage and second stage preparation processes. (That is, the preparation process of “progress degree 3”) is completed. In this case, the display processing terminal 20 can display the display content on the display device 40 only by performing the final process (that is, in a very short time).

FIG. 3 is a diagram illustrating an example of a hardware configuration of the information display system according to the first embodiment. FIG. 3 shows a situation where a person 60 walking in area # 1 moves to area # 2. Based on the sensing data D0 acquired when the person 60 is in the area # 1, the system control device 30 determines the event occurrence probability that is the probability of occurrence of a situation in which the person 60 reaches the display device 40 in the area # 2.

<< 1-2 >> Operation FIG. 4 is a flowchart showing an example of operations of the sensing device 10 and the system control device 30 of the information display system according to the first embodiment.

In step S11, the camera as the sensing device 10 shoots the area and generates video data as the sensing data D0. The sensing device 10 may include a wireless LAN (Local Area Network) (registered trademark) receiver that receives a wireless signal transmitted from a mobile terminal possessed by a moving person (for example, a pedestrian). In this case, the sensing device 10 can acquire attribute information that a person has registered in advance in his mobile terminal, and the sensing data D0 includes attribute information. The attribute information can include, for example, one or more of a person's language, sex, age, origin, preference, and the like.

In step S12, the situation recognition unit 31 detects a person from the video data acquired from the sensing device 10 and generates first information D1 including the detected position of the person and identification information of the person. The person identification information may include a person identification number (ID) and person characteristic information. The feature information can include, for example, a person's height, weight, clothes, belongings, and the like. The first information D1 may include the moving direction of the person and the moving speed of the person. The situation recognition unit 31 may recognize person attribute information. The person identification information may include person attribute information and a person identification number. When the sensing device 10 includes a receiver, the situation recognizing unit 31 may include attribute information acquired from the mobile terminal possessed by the person in the person identification information. In addition, the situation recognition unit 31 may handle information about a person whose moving speed is equal to or higher than a predetermined speed so as not to be included in the first information D1. This is because a person who moves at a moving speed equal to or higher than a certain speed (for example, a running person) is highly likely not to see the display device 40.

In step S13, the situation prediction unit 32 predicts an event occurrence probability that is an occurrence probability of a situation in which the detected person moves in front of the display device 40 in each area. The situation prediction unit 32 is a list (for example, a data table) as event occurrence probability derivation information indicating a correspondence relationship between a person detection position or an area where a person is present and a display device 40 that is a target for predicting the event occurrence probability. May be created in advance, and using this list, one or more display devices 40 corresponding to the camera that is the sensing device 10 that has detected the person and for which the event occurrence probability is predicted may be determined. In addition, the situation prediction unit 32 selects one or more display devices 40 that are targets for predicting the event occurrence probability based on the event occurrence probability for the detected person and the scheduled time to reach each display device 40. You may decide. Further, the situation prediction unit 32 may store only persons whose event occurrence probability is equal to or higher than a predetermined value and discard information on other persons. When the estimated arrival time is shorter than a predetermined time, the situation prediction unit 32 generates an event for a display device with a short estimated arrival time (that is, a display device that is considered unable to present the display content in time). The probability may not be predicted.

In step S14, the control command determination unit 33 determines display content to be presented to each detected person, and generates identification information of the detected person and event information D1a associated with the detected person.

In step S15, the control command determination unit 33 determines whether an event occurrence probability (that is, an event occurrence probability for one person) that is the occurrence probability of a situation where a person reaches the display device 40 or a person with a specific attribute. A display processing terminal that controls the display device 40 in which an event occurrence probability (that is, an event occurrence probability for a plurality of persons) that is a probability of occurrence of a plurality of situations gathered in front of the same display device 40 is a predetermined value or more. 20 is determined.

In step S <b> 16, the control command determination unit 33 determines the preparation progress degree in each corresponding display processing terminal 20 according to the event occurrence probability in each display device 40.

In step S17, the control command determination unit 33 instructs each display processing terminal 20 according to the degree of preparation progress.

FIG. 5 is a flowchart showing an example of processing in step S17 of FIG. In the first embodiment, in order to simplify the description, the system control device 30 has an event occurrence probability (that is, an event occurrence probability) of 50% or more of the event that the target person who presents the display content reaches the display device 40. In this case, the processing data D3a is distributed to the display processing terminal 20, and the preparation progress in the display processing terminal 20 is advanced to the first stage (that is, the progress 1). Further, when the event occurrence probability is 70% or more, the system control device 30 advances the preparation progress degree in the display processing terminal 20 to the preparation process of the second stage (that is, the progress degree 2). Further, when the event occurrence probability is 85% or more, the system control device 30 advances the preparation progress degree in the display processing terminal 20 to the preparation process of the third stage (that is, the progress degree 3).

For example, in step S21, the control command determination unit 33 determines whether or not the event occurrence probability is 50% or more for the display control terminal 20 in each area and the processing data D3a has not been distributed to the display processing terminal 20. To do. If the process data D3a has not been distributed and the event occurrence probability is 50% or more, the control command determination unit 33 advances the process to step S22. When the processing data D3a has been distributed, or the event occurrence probability is less than 50%, or the processing data D3a has been distributed and the event occurrence probability is less than 50%, the control command determination unit 33 performs the processing. Proceed to step S23.

In step S22, the control command determination unit 33 distributes the processing data D3a to be distributed to the display processing terminal 20 in each area. That is, the system control device 30 causes the display processing terminal 20 in each area to receive the processing data D3a and the like, and causes the first stage (that is, the degree of progress 1) to perform the preparation processing.

In step S23, the control command determination unit 33 determines that the event occurrence probability is 85% or more for the display control terminal 20 in each area and the preparation progress degree of the processing data D3a in the display processing terminal 20 is the third stage (that is, the progress degree). It is determined whether or not 3). If the event occurrence probability is 85% or more and the preparatory process for the third stage (ie, degree of progress 3) has not been performed, the control command determination unit 33 advances the process to step S24. When the event occurrence probability is less than 85% or when the preparatory process of the third stage (that is, the degree of progress 3) is not performed or the event occurrence probability is less than 85%, That is, when the preparation process of progress 3) is not performed, the process proceeds to step S25.

In step S24, the control instruction determination unit 33 sets the third stage preparation process (ie, progress degree 3) as the preparation progress degree in the control instruction information D3 that transmits the processing data D3a to the display control terminal 20 in each area. To do.

In step S25, the control command determination unit 33 determines whether the event occurrence probability is 70% or more for the display control terminal 20 in each area. If the event occurrence probability is 70% or more, the control command determination unit 33 advances the process to step S26. In step S25, the control command determination unit 33 ends the process when the event occurrence probability is less than 70%.

In step S26, the control command determination unit 33 determines whether or not the second stage preparation process (ie, progress degree 2) is not performed as the preparation progress degree of the processing data D3a at the display processing terminal 20 in each area. If the second stage preparation process has not been performed, the control instruction determination unit 33 advances the process to step S27. In step S26, if the second-stage preparation process (that is, the degree of progress 2) has been performed, the control command determination unit 33 advances the process to step S28.

In step S27, the control instruction determination unit 33 sets the second stage preparation process as the degree of preparation progress in the control instruction information D3 that transmits the processing data D3a to the display processing terminal 20.

In step S28, the control command determination unit 33 transmits control command information D3 including the setting of the preparation progress level to the display processing terminal 20.

In step S31, the distribution data receiving unit 26 receives the distributed data. In step S <b> 32, the distribution data receiving unit 26 stores the received data in the data storage unit 23.

FIG. 7 is a flowchart showing an example of an operation when receiving a control command in the display processing terminal 20 of the information display system according to the first embodiment.

In step S41, the process progress control unit 22 receives the control command information D3 transmitted from the control command transmission unit 34 via the control command reception unit 21.

In step S42, the process progress control unit 22 extracts the preparation progress information D3b from the control command information D3, and extracts content identification information for identifying display content.

In step S43, the processing progress control unit 22 and the data processing unit 24 proceed with the display content preparation process based on the preparation progress information D3b, and store information related to the preparation process in each data storage unit 23.

FIG. 8 is a diagram showing the contents of the preparation process according to the preparation progress in step S43 of FIG.

When the preparation process of the first stage (that is, the degree of progress 1) is set as the degree of preparation progress, the control command determination unit 33 instructs the distribution processing unit 35 to distribute the display content. The display processing terminal 20 stores display content such as an HDD that is a mass storage device of the data storage unit 23, for example.

When the preparation process of the second stage (that is, the degree of progress 2) is set as the preparation progress degree, the display processing terminal 20 executes the preparation process of the second stage. For example, the data processing unit 24 of the display processing terminal 20 reads and decodes the image file encoded in the main memory in the data storage unit 23 and stores the decoded data in the main memory.

When the preparation process of the third stage (that is, the degree of progress 3) is set as the preparation progress degree, the display processing terminal 20 executes the preparation process of the third stage. For example, the data processing unit 24 of the display processing terminal 20 transfers the image data on the main memory to the video memory in the data storage unit 23.

When the preparation progress is in the second stage or later in the moving image display, the display processing terminal 20 may construct a pipeline for reading and reproducing the moving image file. When the preparation progress is the third stage in the moving image display, the display processing terminal 20 may reproduce the moving image file for several frames in advance and buffer it on the video memory.

When the preparation progress is the second stage in CG (Computer Graphics) display, the display processing terminal 20 may read the vertex data, texture image data, motion data, etc. to be reproduced and expand them on the main memory. . When the preparation progress is the third stage in the CG display, the display processing terminal 20 may buffer the data on the main memory on the video memory.

FIG. 9 is a flowchart showing an example of an operation when an event occurs in the display processing terminal 20 of the information display system in the first embodiment (when the target person arrives in front of the display device 40).

In step S51, the processing data selection unit 25 detects event information D1a (identification information of the target person in front of the display processing terminal) from the first information D1 transmitted from the situation recognition unit 31.

In step S52, the processing data selection unit 25 determines the processing data D3a to be output based on the event information D1a.

In step S53, the processing data selection unit 25 outputs the processing data D3a. In the first embodiment, the display content selected in step S52 is displayed. If there is an unimplemented preparation process for the display content at the time of execution of step S53, the process data selection unit 25 collectively executes the unimplemented preparation process and the final process. Alternatively, if there is an unprepared preparation process for the display content when step S53 is performed, the processing data selection unit 25 may complete the process without displaying the display content.

In step S52, when the processing data selection unit 25 receives the scheduled processing time, that is, the scheduled display time of the display content, the processing data selection unit 25 may perform display processing at the scheduled display time in step S53. Thereby, information can be presented to the target person at a more appropriate timing.

<< 1-3 >> Effect As described above, according to the information display system and the information display method according to the first embodiment, the progress of the output preparation process for the processing data D3a that is the display content is performed based on the event occurrence probability. Control. As a result, a lot of output preparation processing of the processing data D3a for an event having a high event occurrence probability is advanced, and the processing time until the final output data creation is completed can be greatly shortened. On the other hand, the output preparation process of the processing data D3a for an event having a low event occurrence probability is advanced to reduce the processing time until the final output data creation is completed. By such control, it is not necessary to store all the data immediately before the output of the processing data D3a in the data storage unit 23 having a limited storage capacity, and the event occurrence probability in the data immediately before the output of the processing data D3a is increased. A corresponding amount of data may be stored in the data storage unit 23. Specifically, a person who moves in the area is detected, and information for the person is presented to the display processing terminal 20 of the display device 40 in each of the movement destination areas of the person at an appropriate timing. can do.

<< 1-4 >> Modifications When each display processing terminal 20 stores processing data D3a as display content in advance, the distribution processing unit 35 of the system control device 30 and the distribution data reception of each display processing terminal 20 It is not necessary to provide the part 26.
