Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram illustrating an overall configuration of the content distribution system 1.
As illustrated in FIG. 1, the content distribution system 1 includes a distribution server 2, a projector 3, a printer 4, and an IoT sensor 5 attached to a lighting device, an audio device, or the like. Connected to each other through. Furthermore, a host terminal 900 used by a user on the host side of the event and a guest terminal 950 used by a user on the guest side of the event are connected to the distribution server 2 via the network 7.

  The distribution server 2 is an example of the content distribution control device according to the present invention, and is a computer terminal on which the distribution program 22 (Web program) operates, but is not limited thereto. The distribution server 2 of this example detects a trigger related to the progress of the event based on the detection result from the IoT sensor 5 or the like, and transmits or transmits the content data by the host terminal 900 and the guest terminal 950 according to the detected trigger. The distribution direction of the content data is controlled by permitting or prohibiting the reception.

  The projector 3 is an example of a display device according to the present invention, and displays content based on content data received from a user (host terminal 900 or guest terminal 950). For example, the projector 3 projects image data posted from the guest terminal 950 on a screen according to an instruction from the distribution server 2.

  The printer 4 is a printing device that prints an image according to an instruction from the distribution server 2. For example, the printer 4 prints image data posted from the guest terminal 950 in accordance with an instruction from the distribution server 2.

  The IoT sensor 5 is a sensor with a communication function that detects a state of a device or a device. For example, the IoT sensor 5 is attached to a lighting device, an audio device, or the like, detects On / Off of a switch of the lighting device, the audio device, or the like, and transmits a detection result to the distribution server 2. The IoT sensor 5 of this example is attached to a lighting device such as a spotlight, an audio device such as a microphone, a human sensor, a door opening / closing sensor for detecting opening and closing of a door, and a curtain opening / closing sensor of a system for opening and closing a curtain. And transmits these states to the distribution server 2.

  The host terminal 900 and the guest terminal 950 are portable computer terminals operated by a user. More specifically, the host terminal 900 is a computer terminal operated by a user on the host side (organizer side) of the event, and the guest terminal 950 is a computer terminal operated by a user on the guest side (participant side) of the event. The host terminal 900 and the guest terminal 950 of this example are smartphones on which a Web program that operates on the Web operates, and can transmit the position information of the terminal to the outside based on a GPS signal.

FIG. 2 is a diagram illustrating the relationship between the progress of the event and the content distribution. In this example, a wedding is described as an example of an event, but the present invention is not limited to this.
As illustrated in FIG. 2, the wedding hall includes a plurality of halls (in this example, “chapel A” for a wedding and “banquet hall B” for a reception). Further, the chapel A includes the inside of the chapel where the wedding is performed (section A1) and the entrance area where the bouquets and the like are performed (section A2). Similarly, the reception hall B includes a section B1 in which the bride and groom seats are provided, a section B2 in which the guest seats are provided, and a lobby (section B3). The bride and groom, who are the hosts of the wedding, and the guests of the wedding participate in sub-events (ceremonies, bouquets, commemorative photography, receptions, etc.) while moving through these sections.
In each of these sub-events, effects are produced, and the content distribution is performed by the content distribution system 1 as a part thereof. Therefore, it is preferable that the content distribution by the content distribution system 1 is in accordance with the progress of the event. Further, since the content distribution is a part of the effect, it is preferable to distribute the content only to the guests who actually participate in the event.
Therefore, the content distribution system 1 according to the present embodiment detects a trigger related to the progress of an event based on the time, the position of the host terminal 900 or the guest terminal 950, and On / Off of a microphone or a spotlight, and detects the detected trigger. , The transmission and reception of content data by the host terminal 900 and the guest terminal 950 are controlled. Particularly, in this example, since the event is a guest participation type event, it is important to control transmission and reception of content data by the guest. For example, when a guest is asked to post an image (still image taken during a bouquet or commemorative photo) at a good timing, or when the guest is projecting an image on a screen during a reception, the guest can download and upload content. It is important for production to prohibit and get attention on the screen.

FIG. 3 is a diagram illustrating a hardware configuration of the distribution server 2.
As illustrated in FIG. 3, the distribution server 2 has a CPU 200, a memory 202, an HDD 204, a network interface 206 (network IF 206), a display device 208, and an input device 210. These components are mutually connected via a bus 212. Connected.
The CPU 200 is, for example, a central processing unit.
The memory 202 is, for example, a volatile memory and functions as a main storage device.
The HDD 204 is, for example, a hard disk drive, and stores a computer program (for example, the distribution program 22 in FIG. 4) and other data files as a nonvolatile recording device.
The network IF 206 is an interface for performing wired or wireless communication.
The display device 208 is, for example, a liquid crystal display.
The input device 210 is, for example, a keyboard and a mouse.

FIG. 4 is a diagram illustrating a functional configuration of the distribution server 2.
As illustrated in FIG. 4, the distribution program 2 is installed in the distribution server 2, and a content database 260 (content DB 260) and a setting information database 270 (setting information DB 270) are configured. The distribution program 22 is stored in a recording medium such as a CD-ROM, for example, and is installed in the distribution server 2 via the recording medium.
A part or all of the distribution program 22 may be realized by hardware such as an ASIC, or may be realized by partially borrowing the function of an OS (Operating System). Further, all of these programs may be installed on one computer terminal, or may be installed on a virtual machine on a cloud.

The distribution program 22 includes a trigger detection unit 220, a distribution direction control unit 222, a content reception unit 224, a content transmission unit 226, a content selection unit 228, a display control unit 230, and a printing unit 232.
In the distribution program 22, the trigger detection unit 220 detects a trigger related to the progress of the event. Here, detection of a trigger means detecting that a preset trigger condition is satisfied. For example, the trigger detecting unit 220 detects that the host terminal 900 or the guest terminal 950 is present in a predetermined area (for example, the section A2 in FIG. 2) as a trigger. Further, the trigger detection unit 220 may detect, as a trigger, the arrival of the time defined in the scenario according to the scenario of the event, or may detect, as a trigger, a switching operation of an audio device or a lighting device used in the event. Alternatively, these combinations may be detected as triggers.
The trigger detection unit 220 detects that the distance between the user (eg, host) belonging to the first user group and the user (eg, guest) belonging to the second user group has become a predetermined range. May be detected.
The trigger detection unit 220 may detect, as a trigger, that the number or data amount of content data transmitted from the guest-side user falls within a predetermined range.

  The distribution direction control unit 222 controls the distribution direction of the content data by permitting or prohibiting the transmission or reception of the content data by the user according to the trigger detected by the trigger detection unit 220. The distribution direction of the content data is, for example, the host terminal 900 to the guest terminal 950, the guest terminal 950 to the host terminal 900, the host terminal 900 or the guest terminal 950 to the distribution server 2, and the distribution server 2 to the host terminal 900 or the guest terminal. 950. For example, the distribution direction control unit 222 transmits content data from the first user group (host side) to the second user group (guest side) in response to a trigger detected by the trigger detection unit 220, or Transmission of content data from the second user group (guest side) to the first user group (host side) is permitted.

  In addition, the distribution direction control unit 222 determines that the user (the host terminal 900 or the guest terminal 950) exists outside the predetermined area including the event location, or when the time is outside the predetermined period including the event holding time. In addition, transmission and reception of content data are prohibited.

  The content receiving unit 224 receives content data from the host terminal 900 or the guest terminal 950 according to the control from the distribution direction control unit 222, and stores the received content data in the content DB 260. The content receiving unit 224 of this example receives content data from a user group (host terminal 900 or guest terminal 950) permitted by the distribution direction control unit 222.

  The content transmission unit 226 transmits the content data to the host terminal 900 or the guest terminal 950 according to the control from the distribution direction control unit 222. The content data may be transmitted to the host terminal 900 or the guest terminal 950 in a push type, or may be transmitted in response to a request from the host terminal 900 or the guest terminal 950. The content transmission unit 226 of this example reads out the content data selected by the content selection unit 228 from the content DB 260 and transmits the user data to the user group (host terminal 900 or guest terminal 950) permitted by the distribution direction control unit 222. I do.

  The content selection unit 228 selects content to be transmitted or displayed from the content data received from the user (host terminal 900 or guest terminal 950) according to the characteristics of the trigger detected by the trigger detection unit 220. For example, the content selection unit 228 selects, from among the content data received from the host terminal 900 and the guest terminal 950, the content data received from the host terminal 900 according to the characteristics of the trigger detected by the trigger detection unit 220, or The content data received from the guest terminal 950 is selected.

  The display control unit 230 permits display of content based on content data transmitted from the guest user (guest terminal 950). The display control unit 230 in this example causes the projector 3 to project the content data selected by the content selection unit 228.

  The printing unit 232 prints an image and information for accessing another content based on the image data transmitted from the user. For example, the printing unit 232 transmits the content data (still image) received from the host terminal 900 or the guest terminal 950 and a QR code (registered trademark) for accessing the content including the host side user's participation thanks message. The printer 4 is controlled to print on one print medium.

FIG. 5A illustrates trigger setting information registered in the setting information DB 270, and FIG. 5B illustrates user group information registered in the setting information DB 270.
As illustrated in FIG. 5A, the trigger information and the control content are registered in the setting information DB 270 in association with each other. For example, in the trigger condition, a combination of the arrival of a predetermined date and time and the fact that the user is present in a predetermined area (for example, section A) is set. That is, the trigger detection unit 220 refers to the trigger setting information and detects that a predetermined date and time (10:00 on August 19, 2018) has arrived and that the guest terminal 950 is present in the section A as a trigger. The distribution direction control unit 222 instructs automatic distribution (push-type distribution) of the content (file A) from the distribution server 2 to the guest terminal 950.
Similarly, at 11 o'clock on August 19, 2018, and when it is detected as a trigger that the host terminal 900 and the guest terminal 950 are present in the section A and the microphone is turned on, the host terminal 900 Transmission of content data to the guest terminal 950 is permitted. In addition, it is detected as a trigger that at 15:00 on August 19, 2018, the guest terminal 950 is present in the section B, the projector 3 is turned on, and the music file A is reproduced by the audio device. Then, the upload of the content data from the guest terminal 950 to the distribution server 2 is permitted.

  Users involved in the event are managed by being divided into a plurality of user groups. In this example, as illustrated in FIG. 5B, a terminal operated by a user on the host side of the event is managed as a host terminal 900, and a terminal operated by a user on the guest side of the event is defined as a guest terminal 950. Be managed. In this example, a form in which two types of user groups, an event host and a guest, are defined will be described as a specific example. However, the present invention is not limited to this, and three or more user groups may be defined. Good.

FIG. 6 is a diagram exemplifying content selection setting information registered in the setting information DB 270.
As illustrated in FIG. 6, in the setting information DB 270, the type of content selected by the content selection unit 228 is registered in association with the characteristics of the trigger. For example, with respect to a trigger related to lighting, when it is estimated that the lighting device is turned on and a specific section is brighter than a reference, selection of an audio file is permitted and selection of an image file is prohibited.
As described above, it is possible to set such that a content that reduces the effect of the effect due to the characteristics of the trigger is not selected.

FIG. 7 is a flowchart illustrating the content distribution process (S10) by the distribution server 2.
As illustrated in FIG. 7, in step 100 (S100), the trigger detection unit 220 of the distribution server 2 waits until a start trigger is detected, and when a start trigger is detected, the process proceeds to S105. The start trigger is, for example, the arrival of a preset time (such as a wedding reception start time).

In step 105 (S105), the trigger detection unit 220 collects the detection result received from the IoT sensor 5, the position information received from the host terminal 900 and the guest terminal 950, the current time, and the like as trigger elements.
In step 115 (S115), the trigger detection unit 220 proceeds to the process of S120 when the collected trigger element matches any of the trigger conditions, and proceeds to S105 when the collected trigger element does not match any of the trigger conditions. Return.

In step 120 (S120), the trigger detection unit 220 notifies the distribution direction control unit 222 of the control content corresponding to the detected trigger.
The distribution direction control unit 222 controls transmission and reception of content data according to the control content notified from the trigger detection unit 220. The transmitted / received content data is selected by the content selection unit 228.

  In step 125 (S125), the trigger detection unit 220 determines whether or not an end trigger has been detected. If the end trigger has been detected, the process proceeds to step S135. If the end trigger has not been detected, the process proceeds to step S105. Return to the processing of. The end trigger is, for example, the arrival of a preset time (n hours after the end of the reception).

  In step 135 (S135), the distribution direction control unit 222 deletes the content data stored in the content DB 260.

  As described above, the content distribution system 1 distributes content data at a timing that matches a preset trigger condition.

FIG. 8 is a diagram illustrating an example of the relationship between the disclosure / non-disclosure of the content and the progress of the event.
As illustrated in FIG. 8, in the event preparation period, a pre-registration period in which guests can upload content in advance can be set. In this case, when the trigger detection unit 220 detects the arrival of the pre-registration period (May 1, 2018), the distribution direction control unit 222 permits the transmission of the content from the guest terminal 950 to the distribution server 2 and And the transmission from the distribution server 2 to the guest terminal 950 is prohibited, and the pre-registered content is kept private. The host terminal 900 can refer to the content registered in advance by the distribution direction control unit 222.
Even on the day of the event, a pre-registration period (7:00 to 10:00) can be set before the event holding time (10:00 to 16:00).
Then, when the event holding time has arrived and the trigger detection unit 220 detects that the guest terminal 950 is present in a section within a radius of 20 m of the venue, the distribution direction control unit 222 determines the distribution server 2 is permitted to be transmitted to the guest terminal 950 so that the guest can refer to it. In this example, the public content can be referred to by the dedicated application installed in the guest terminal 950, and if the public content is set to SNS distribution disabled, it can be browsed only within this dedicated application. Yes, SNS distribution is prohibited.

FIG. 9A is a diagram exemplifying a case where content is distributed by a trigger by a human sensor, and FIG. 9B is a diagram exemplifying a case where content is distributed triggered by passage of a plurality of points. It is.
As illustrated in FIG. 9A, a human sensor to which the IoT sensor 5 is connected is installed in a specific section of the hall (in this example, Dandan), and the trigger detection unit 220 is connected to the guest terminal. If the event 950 is present in the venue, the time of the event has arrived, and the presence sensor has detected the detection of a person's appearance as a trigger, the distribution direction control unit 222 The distribution of the content data to the terminal 950 is started. For example, at the timing of the performer's presentation, content related to the performance can be delivered to the guests in the venue, and timely production can be achieved. If the content is distributed only according to the time schedule, it is not possible to respond when the performer's stage is delayed, etc. Content distribution becomes possible.

  Further, as illustrated in FIG. 9B, the trigger condition may be that the host terminal 900 has passed a plurality of points (points A and B). For example, in the scenario, when the host user passes the point A and then distributes the content at the timing of arriving at the point B, if only the arrival at the point B is set as a trigger condition, the host user is inadvertently Even if the user stops at the point B, the content is distributed. Using the passage of a plurality of points as a trigger condition is preferable because the content distribution according to the scenario is performed only when the user moves along the scenario.

FIG. 10A is a diagram exemplifying a case where a content posting is received by using a microphone On as a trigger, and FIG. 10B is a diagram showing a case where content is distributed by combining a time defined in a scenario with another trigger element. It is a figure which illustrates the case where it does.
As illustrated in FIG. 10A, an IoT sensor 5 is connected to a microphone installed in the venue, and a beacon transmitter is installed in the center of the venue. When the trigger detection unit 220 detects, as a trigger, that the microphone connected to the IoT sensor 5 is turned on and that the guest terminal 950 is in a range where a beacon signal can be received from a beacon transmitter, the distribution direction is set. The control unit 222 permits uploading of content data from these guest terminals 950. For example, the distribution server 2 can accept the upload of a photo from the timing when the moderator calls for uploading a photo using a microphone.

Further, as exemplified in FIG. 10B, a dynamic distribution period of the content can be set on the scenario, and another trigger condition can be added to these distribution periods. For example, for the dynamic distribution period A, the fact that the number of guest terminals 950 in the venue is equal to or greater than the reference value is used as a trigger element for projector projection, and for the dynamic distribution period B, the guest terminal 950 uploads the distribution server 2. The fact that the number or the data size of the performed photos is equal to or larger than the reference value is set as a print trigger element. In this case, when the trigger detection unit 220 detects that the dynamic distribution period A has arrived and that the number of existing guest terminals 950 in the venue has exceeded the reference value, the distribution direction control unit 222 In step 3, the display controller 230 is instructed to project a content (such as a slide show). Thus, for example, when the number of guests in the reception hall reaches a certain number or more, projector projection can be started.
When the trigger detection unit 220 detects that the dynamic distribution period B has arrived and that the number of photos or data details uploaded from the guest terminal 950 has exceeded the reference value, the distribution direction control unit 222 And instructs the printing unit 232 to print the photo uploaded to the distribution server 2 by the printer 4. The printed matter 8 to be printed includes, for example, a photograph (content 800) uploaded from a guest and access information 802 for accessing another content (moving image provided by the host), as illustrated in FIG. including. The printed matter 8 allows not only the sharing of the content between the guests, but also the interaction between the guest and the host via the printed matter 8.

As described above, according to the content distribution system 1 of the present embodiment, the distribution direction of the content data can be controlled according to the trigger related to the progress of the event. Thereby, according to the progress of the event, it is possible to broadcast the content from the host to the guest all at once or to receive the posting of the content from the guest. It is particularly suitable for guest participation events.
Further, by using On / Off of an audio device or a lighting device as a trigger element, timely content distribution can be realized even when an event progresses behind a scenario.

[Modification 1]
Next, a modified example of the above embodiment will be described.
In the first modification, a case will be described in which a plurality of sub-events are prepared in the event, and the progress of the sub-event is determined according to the number of votes cast by the guests for the sub-event. That is, the number of votes of the guest for the sub-event is a trigger element.
FIG. 12 is a diagram illustrating an example of the result of counting the number of votes for sub-events.
As illustrated in FIG. 12, the trigger detection unit 220 counts the number of votes for each sub-event, and on the condition that the total number of votes exceeds a reference value set for each sub-event, Is notified to start, and the distribution direction control unit 222 automatically distributes the content for starting the sub-event according to the notification.
In this example, the sub-event B and the sub-event C are set at the same time and at the same venue, and one of the sub-events is performed in advance according to the number of votes cast by the guest. That is, the scenario branches, and the content and order of the events change according to the voting of the guest.
Thereby, it is possible to more strongly encourage the guest to participate in the event.
