  In the following, the connection device and the image display system will be described taking a live concert of an idol group X (artist) composed of two members A and B as an example. However, the environment using the connection device and the image display system of the present invention is not limited to various concerts such as live concerts, classical concerts, and film concerts. For example, operas, musicals, plays such as kabuki, circus, baseball, Soccer, rugby, horse racing, track and field, golf, basketball, marathon, sumo, judo, gymnastics, figure skating, motor sports, boxing and other sports (indoor and outdoor) games, motor shows, games It may be various events such as shows, medical equipment, industrial equipment exhibitions, and the like.

  First, the concert hall equipment will be briefly described. The concert hall is provided with a stage where the idol group X climbs, a plurality of cameras CA for photographing (imaging) the idol group X from various angles, and a large screen. ing. Images taken by a plurality of cameras CA are displayed on a large screen, used for live broadcasting to other venues, used for a TV program to be broadcast later, DVD, BD ( Blu-ray (registered trademark) Disc) and the like. An image selected by the person in charge from among images obtained from a plurality of cameras is displayed on the large screen. Therefore, from the viewpoint of each spectator, an image that he / she wants to see (for example, an image of a member who is his / her fan) is not always displayed on the large screen. The above-described configuration is a conventional general live concert system, and the superiority of the connection device and the image display system of the present invention is to the conventional general live concert system. It can be easily integrated.

  Hereinafter, the connection device and the image display system of the present invention will be described in detail. The “image” in the present specification includes both a moving image (video) and a still image, and may be either.

  In brief, the image display system 100 is a system that distributes to the image display terminal 200 an image suitable for each spectator using the image display terminal 200 in real time. According to such an image display system 100, for example, even when the seat is far from the stage and the idol group X cannot be seen well, or when the idol group X is not visible because the audience in the front seat is tall, The idle group X can be viewed by the image display terminal 200. Also, for example, it is possible to see the facial expressions of members A and B and performance techniques (for example, hand of guitar performance) that cannot be confirmed with the naked eye. Therefore, the audience can enjoy the live concert more.

  The image display terminal 200 is not particularly limited. For example, a smartphone, a tablet terminal, a notebook computer, a head-mounted display that is attached to the audience's head, a contact lens type display device that is attached to the audience's eyeball, and a film A display device of a type, for example, a wearable terminal worn on the arm like a watch, a monitor installed in front of the audience (for example, the back of the backrest of the front seat), a 3D hologram, or the like can be used.

  Further, the image display terminal 200 may be a terminal owned by an individual audience, or a terminal provided (lent or transferred) by a live concert organizer (including related parties). In this embodiment, a case where a smartphone owned by an individual audience is used as the image display terminal 200 will be described as a representative. By using a widespread smartphone as the image display terminal 200, the image display system 100 can be provided to more spectators. Moreover, the cost of the image display system 100 can be reduced by using a terminal owned by the individual audience as the image display terminal 200.

  When the organizer of the live concert lends the image display terminal 200 to the audience, the image display terminal 200 is lent to the desired audience at the venue before the live concert starts, and after the live concert ends, the image display terminal 200 at the venue. However, it is preferable to take a method of depositing compensation money at the time of lending and returning compensation money at the time of return. According to such a method, for example, it is possible to suppress an adverse effect that a spectator takes home without returning the image display terminal 200.

  The image display terminal 200 has been described above. The image display system 100 implemented using such an image display terminal 200 is configured to display an image captured by the camera CA on the image display terminal 200. More specifically, the image display system 100 acquires a plurality of images captured by a plurality of cameras CA, and displays a first display state (multi-image display) in which the two or more acquired images are displayed on the image display terminal 200. State) and a second display state (selected image display state) for displaying an image selected from two or more images displayed in the first display state.

  As shown in FIG. 1, such an image display system 100 includes an image acquisition unit 110 that acquires images (live video) from a plurality of cameras CA and a plurality of cameras CA acquired by the image acquisition unit 110. An image generation unit 120 that generates a multi-image signal from the image of the image, a distribution unit 130 (transmission unit) that performs streaming distribution (transmission) of the multi-image signal generated by the image generation unit 120, a network 140, It has a connection device 150 that is connected and used, and a data server 160 that stores session data of each image display terminal 200.

  The image acquisition unit 110 acquires images from a plurality of cameras CA. The number of images acquired by the image acquisition unit 110 is not particularly limited, and can be set as appropriate depending on the scale of the live concert, the number of members of the artist, and the like. The image acquisition unit 110 may acquire images from all installed cameras CA, or may acquire images from some selected cameras CA. Moreover, when acquiring an image from some selected cameras CA, selection of camera CA may be changed freely during a live concert.

  The image generation unit 120 generates a multi-image MS (multi-image image data) from a plurality of images from a plurality of cameras CA acquired by the image acquisition unit 110. That is, the multi-image MS includes images of a plurality of cameras CA in one image. A plurality of images included in the multi-image MS are synchronized with each other. That is, the multi-image MS includes a plurality of images at substantially the same time.

  Such a multi-image MS can be configured, for example, as shown in FIG. The multi-image MS shown in FIG. 2 has a total of eight image areas S1 to S8 divided in length × width = 2 × 4, and images P1 to P8 are displayed in the image areas S1 to S8, respectively. It is like that. Each of the images P1 to P8 is any of a plurality of images acquired by the image acquisition unit 110.

  For example, when the image acquisition unit 110 acquires images from eight cameras CA, all these images are displayed in the image areas S1 to S8 as images P1 to P8. When the image acquisition unit 110 acquires images from nine or more cameras CA, eight images selected from these images are displayed in the image areas S1 to S8 as images P1 to P8. . In addition, although it is preferable to select another image for each of the image areas S1 to S8, the same image may be selected in at least two areas of the image areas S1 to S8. The number of image areas included in the multi-image MS is not particularly limited, and may be 2 to 7, or 9 or more.

  The distribution unit 130 encodes the multi-image MS generated by the image generation unit 120 for live streaming, and distributes the streaming via the network 140. The network 140 is not particularly limited and may be wireless or wired. However, for example, it is preferable to use a wireless LAN (local area network) such as Wi-Fi (registered trademark). Further, it may be a network that is permanently installed in a live concert venue, or a network that is set up by a live concert organizer.

  As described above, by distributing the multi-image MS including the images P1 to P8, for example, it is possible to reduce the communication data capacity as compared with a case where images acquired from a plurality of cameras CA are respectively distributed. Therefore, smoother and more stable distribution is possible.

  The connection device 150 is a device used by being connected to the image display terminal 200, and as shown in FIG. A storage unit 153, a battery 154, a connector 155 connected to the image display terminal 200, and a regulation unit 157.

  Here, in the connection device 150, it is preferable that the application 151 is activated on the image display terminal 200 only by connecting the connector 155 to the image display terminal 200. That is, in addition to connecting the connection device 150 to the image display terminal 200, the individual viewer does not manually install the application 151 on the image display terminal 200 or manually perform various settings of the application 151. Preferably, the application 151 is started on the 200. Thereby, all the spectators using the connection device 150 can use the application 151 without any confusion.

  In addition, the connection device 150 has a terminal protection function that restricts use in the image display terminal 200 other than the registered image display terminal 200. Thereby, it is possible to prevent one connection device 150 from being reused by two or more image display terminals 200. Therefore, it is possible to suppress a decrease in the profit of the provider of the image display system 100 and to ensure fairness among users of the connection device 150. As a mechanism of such a terminal protection function, for example, the identification ID of the image display terminal 200 connected first is acquired and registered, and thereafter, it can be used only by the image display terminal 200 of the registered identification ID. To do. Note that such a terminal protect function may not be provided. Further, the number of image display terminals 200 that can be used by one connection device 150 is not limited to one, and may be two or more.

  In addition, the connection device 150 has an event protection function that restricts the use of the application 151 other than registered events. This prevents the application 151 from being reused for different events. Therefore, it is possible to suppress a decrease in the profit of the provider of the image display system 100 and to ensure fairness among users of the connection device 150. Note that the event protection function may not be provided.

  Next, a communication method using the image display terminal 200 and the connection device 150 will be described based on FIG.

  In the communication method shown in FIG. 4, first, some image display terminals 200 among a plurality of image display terminals 200 that have a wireless LAN communication unit and can be connected to the network 140 are set as parent nodes 200A (upper terminals). select. As the parent node 200A, for example, an image display terminal 200 having a good communication state with the network 140 such as close to an access point to the network 140 is selected.

  For example, when the application 151 is started on the image display terminal 200, the connection state between the image display terminal 200 and the network 140 is confirmed, and the image display terminal 200 with a good connection state is selected as the parent node 200A. Good. Further, for example, if the image display terminal 200 has a GPS function, the distance between the image display terminal 200 and the access point is obtained using the GPS function, and the image display terminal 200 with a short distance is set as the parent node 200A. You may choose. Note that the connection device 150 may have a GPS function and obtain the distance to the access point instead of the image display terminal 200. Here, since the communication environment changes over time depending on the surrounding situation (environment), it is preferable to periodically select the parent node 200A again.

  The parent node 200A thus selected is connected to the network 140 by the wireless LAN communication unit, and receives the multi-image MS via the network 140. On the other hand, the image display terminal 200 other than the parent node 200A is a child node 200B (lower terminal), and each child node 200B is restricted from being connected to the network 140 by a restriction unit 157 included in the connection device 150. That is, the child node 200B is not connected to the network 140. Thereby, access to the network 140 of the image display terminal 200 other than the parent node 200A can be prevented. Therefore, the number of image display terminals 200 connected to the network 140 can be limited, and the occurrence of communication failures such as a decrease in communication speed and a down (puncture) of the network 140 can be suppressed.

  In the child node 200B, it is preferable that the connection with the network 140 is automatically restricted by the restriction unit 157. The number of parent nodes 200A is not particularly limited, and can be set as appropriate depending on the performance of the network 140 and the like.

  On the other hand, all the image display terminals 200 are connected to each other by the communication unit 152 of the connection device 150. The communication units 152 can be connected to each other by short-range wireless communication (communication not via the network 140) such as Bluetooth (registered trademark).

  Then, using the network 170 constructed by the communication unit 152, the parent node 200A checks the reception status of the multi-image MS between the parent nodes 200A and caches (stores) the received multi-image MS as a child node. Send to 200B. On the other hand, the child node 200B sends the multi images MS to each other while the child nodes 200B confirm and cache the reception status of the multi images MS from the parent node 200A. That is, the plurality of image display terminals 200 transmit and receive the multi-image MS via the network 170 while supplementing data with each other. Note that the network 170 can also be regarded as an overall network that connects a large number of image display terminals 200. For example, the two networks are two parent nodes 200A (two child nodes 200B, one parent node 200A and one child node). 200B). In the latter case, a plurality of networks 170 are formed.

  According to such a method, the multi-image MS can be received as long as it is connected to the network 170. Therefore, for example, even if a certain image display terminal 200 is far away from the access point and cannot be connected to the network 140, as long as it is connected to the network 170, the other image display terminal 200 (connection device 150) is connected. ) To receive the multi-image MS. Further, as described above, since the reception status is mutually confirmed and cached among the plurality of image display terminals 200 (connection device 150), for example, from the parent node 200A ′ in FIG. 4 to the child node 200B ′. Even if the network 170 is interrupted between the multi-image MSs for some reason during transmission of the multi-image MS (when the network 170 is viewed as a whole network, a part of the network 170 is blocked. The multi-image MS is transmitted from another parent node 200A ″ or another child node 200B ″ to the child node 200B ′ via the network 170. Thus, according to the communication method shown in FIG. 4, the reliability of transmission / reception of the multi-image MS can be improved.

  Here, since it is assumed that many spectators (connection devices 150) are crowded in the live venue, the network 170 is more reliably constructed and the number of connection devices 150 connected by the network 170 is also increased. In the communication method as described above, the more the number of image display terminals 200 and the denser the density, the more reliable the network 170 is constructed. From this point of view, the communication method as described above is It can be said that it is particularly suitable for use in live venues.

  As another communication method, for example, a communication method as shown in FIG. 5 may be used. In this communication method, each image display terminal 200 is connected to the network 140 and receives a multi-image MS. Instead of the image display terminal 200, each connection device 150 may be connected to the network 140 and receive the multi-image MS.

  As described above, two examples of the communication method have been described, but the communication method is not particularly limited. In the communication method described above, the image display terminal 200 has a communication function, but the image display terminal 200 may not have a communication function. For this reason, the communication unit 152 of the connection device 150 is preferably configured to be connectable to the network 140. Thereby, even a terminal having no communication function can be used as the image display terminal 200.

  Next, the application 151 will be described. The application 151 is appropriately customized for each event used. Such an application 151 has a function of performing live streaming reproduction of the received multi-image MS on the image display terminal 200 and displaying it on the screen 210 of the image display terminal 200. As described above, the multi-image MS is received by the parent node 200A itself if it is the parent node 200A, and is received by the connection device 150 if it is the child node 200B.

  Further, the application 151 can display a multi-image M on which a plurality of images are displayed on the screen 210 as shown in FIG. Hereinafter, for convenience of explanation, the state in which the multi-image M is displayed is also referred to as a first display state (multi-image display state).

  The multi-image M is not particularly limited. For example, as shown in FIG. 6, the screen 210 is divided into nine image areas SS1 to SS9, and one of the image areas SS1 is set as a main image, and the other images A configuration in which eight image areas SS2 to SS9 are used as sub-images can be given. Then, images P1 to P8 included in the received multi-image MS are displayed in the image areas SS2 to SS9 that are sub-images, and the image area SS1 that is the main image is selected from the images P1 to P8. One image (image P1 in FIG. 6) is displayed. That is, the application 151 divides the multi-image MS (images P1 to P8 combined into one image) into images P1 to P8, and assigns the divided images P1 to P8 to the image areas SS1 to SS9 for display. To do.

  Here, in order to view the images displayed in the image areas SS1 to SS9 without a sense of incongruity, it is important that the images displayed in the image areas SS1 to SS9 are synchronized with each other. In this respect, since the images P1 to P8 included in the multi-image MS are synchronized with each other as described above, the multi-image MS is divided into the images P1 to P9 by dividing the multi-image MS as described above. According to the method for displaying P8, it is not necessary to synchronize the images P1 to P8 on the image display terminal 200 side. Therefore, a function for synchronizing images with the application 151 is not necessary, and the application 151 can be simplified.

  The image areas SS2 to SS9 that are sub-images are displayed in the same size, and the image area SS1 that is a main image is displayed larger than the image areas SS2 to SS9 that are sub-images. In this way, the main image is easily displayed by displaying the main image in a large size.

  The method of displaying the received multi-image MS (images P1 to P8 combined into one image) by dividing it into nine image regions SS1 to SS9 is not particularly limited. For example, the following method is used. Is mentioned.

  One method is a pixel-based method. For example, the application 151 includes information indicating which pixel region (aggregation of pixels) in the multi-image MS includes the images P1 to P8. More specifically, as shown in FIG. 7, for example, the application 151 includes pixels in which the multi-image MS has pixels arranged in 18 rows × 64 columns, and the image P <b> 1 has a pixel area of 1-9 rows × 1-16 columns. The image P2 is composed of pixel regions of 1 to 9 rows × 17 to 32 columns, the image P3 is composed of pixel regions of 1 to 9 rows × 33 to 48 columns, and 1 to 9 rows × 49 to 64. An image P4 is composed of pixel regions of columns, an image P5 is composed of pixel regions of 10 to 18 rows × 1 to 16 columns, and an image P6 is composed of pixel regions of 10 to 18 rows × 17 to 32 columns. The image P7 is configured by a pixel area of ˜18 rows × 33 to 48 columns, and the image P8 is configured by a pixel region of 10 to 18 rows × 49 to 64 columns. Then, based on this information, the application 151 divides the received multi-image MS into images P1 to P8, and displays the divided images in nine image areas SS1 to SS9. According to such a method, the received multi-image MS can be divided into nine image areas SS1 to SS9 and displayed relatively easily. Note that the above-described information may be previously stored in the application 151 or may be received together with the multi-image MS.

  As another method, for example, as shown in FIG. 8, a frame BM that divides the images P1 to P8 is set in the multi-image MS, and the application 151 receives the multi-image received by recognizing the frame BM. The image MS is divided into images P1 to P8, and the divided images are displayed in nine image areas SS1 to SS9. Also by such a method, the received multi-image MS can be divided into nine image areas SS1 to SS9 and displayed relatively easily.

  For example, the application 151 has a function of dividing the received multi-image MS by the above-described method and a function of displaying the image in the image areas SS1 to SS9 corresponding to the divided images. ,have. However, the configuration of the application 151 is not particularly limited.

  The application 151 can switch between the main image and the sub image. That is, for example, as shown in FIG. 9, it is possible to switch from the state in which the image P1 is displayed as the main image to the state in which the image P8 is displayed as the main image. Thereby, since the video which was a sub image until then can be visually recognized as a big main image, each image P1-P8 can be visually recognized clearly.

  A method for switching between the main image and the sub image is not particularly limited, and the method varies depending on the structure of the image display terminal 200 and the connection device 150. For example, as shown in FIG. 9, when touch input with the finger F is possible, touch input (for example, a method of tapping a sub image to be set as a main image, or dragging a sub image to be set as a main image to the image area SS1 Or the like). Further, for example, when the image display terminal 200 or the connection device 150 has a configuration capable of detecting acceleration and angular velocity, it can be switched by physical input (giving vibration, changing direction, etc.). Further, when the image display terminal 200 or the connection device 150 is provided with a physical key, it can be switched by operating the physical key.

  As a modified example of such a multi-image M, for example, configurations shown in FIGS. 10 and 11 can be cited. In the multi-image M shown in FIG. 10, the image area SS1 as a main image is arranged larger than the configuration shown in FIG. 6, and image areas SS2 to SS9 as sub-images are arranged so as to overlap the image area SS1. Has been. On the other hand, in the multi-image M shown in FIG. 11, the image area SS1 that is the main image is located on the most front side of the screen, and the image areas SS2 to SS9 that are sub-images so as to overlap the back side of the image area SS1. Is arranged. In this case, for example, the main image can be switched by scrolling the screen 210 in the horizontal direction.

  Further, the application 151 can display an image selected from the plurality of images P1 to P8 displayed in the first display state (multi-image display state) in full screen. Hereinafter, for convenience of explanation, this state is also referred to as a second display state (selected image display state).

  As shown in FIG. 12, the image displayed in the second display state is the image (image P1 in FIG. 12) that was displayed immediately before as the main image in the first display state, and is displayed in the second display state. The image to be displayed is larger than the main image displayed in the first display state. In the second display state, images (sub-images) other than the selected image (main image) are not displayed. As a result, in the second display state, the main image in the first display state can be further enlarged and displayed, and the sub image is also not displayed. can do).

  The method for switching from the first display state to the second display state is not particularly limited, and differs depending on the structure of the image display terminal 200 and the connection device 150. For example, when touch input to the screen 210 is possible, switching can be performed by touch input (for example, a method of double-tapping or long-tapping the main image). Further, for example, when the image display terminal 200 or the connection device 150 has a configuration capable of detecting acceleration and angular velocity, it can be switched by physical input (giving vibration, changing direction, etc.). Further, when the image display terminal 200 or the connection device 150 is provided with a physical key, it can be switched by operating the physical key. In addition, switching from the first display state to the second display state and switching from the second display state to the first display state can be performed any number of times.

  Furthermore, in the second display state, the displayed image can be enlarged. Thereby, the user can visually recognize more details of the image. The method for enlarging the image is not particularly limited, and differs depending on the structure of the image display terminal 200 and the connection device 150. For example, when touch input to the screen 210 is possible, enlargement / reduction can be performed by touch input (for example, pinch out, pinch in). For example, when the image display terminal 200 or the connection device 150 has a configuration capable of detecting acceleration and angular velocity, the image can be enlarged or reduced by physical input (giving vibration, changing direction, etc.). When the image display terminal 200 or the connection device 150 is provided with a physical key, the enlargement / reduction can be performed by operating the physical key.

  Further, the image displayed in the second display state may be changed without switching to the first display state and changing the main image. That is, for example, the image may be changed from the image P1 to the image P2 in the second display state. Thereby, the operability of the application 151 is improved. The method for changing the image is not particularly limited, and varies depending on the structures of the image display terminal 200 and the connection device 150. For example, when touch input to the screen 210 is possible, the image can be changed by touch input (for example, scrolling in the horizontal direction or the vertical direction). Further, for example, when the image display terminal 200 or the connection device 150 is configured to detect acceleration and angular velocity, the image can be changed by physical input (giving vibration, changing direction, etc.). . When the image display terminal 200 or the connection device 150 is provided with a physical key, the image can be changed by operating the physical key.

  In the present embodiment, the main image is displayed over the entire screen in the second display state, but the size of the image in the second display state is larger than the size of the main image in the first display state. If it does not specifically limit. In the present embodiment, the configuration in which the main image in the first display state is enlarged and displayed in the second display state has been described. However, the image that is enlarged and displayed in the second display state is not limited to this. Sub image may be used. Further, the image that is enlarged and displayed in the second display state is not limited to one, and for example, two images may be enlarged and displayed.

  Although the first display state and the second display state have been described above, the images displayed in these states may or may not include sound. However, it is preferable that no voice is included. As a result, noise can be suppressed and live sound reverberating in the venue can be enjoyed. The application 151 may be configured to display only one of the first display state and the second display state, for example.

  For example, the application 151 may be able to switch the screen 210 to a display state other than the first and second display states. For example, it may be possible to switch to a third display state in which a live concert set list can be confirmed. Thereby, the audience can easily confirm the songs sung in the live concert and their order. Note that the set list displayed in the third display state is limited to songs that are currently sung and songs that have already been sung, and is preferably not displayed for songs that will be sung in the future. Thereby, the confidentiality of the song sung later is ensured.

  Further, the application 151 uses the image display terminal 200 to select a song (for example, a single song, a single CD containing the song, an album CD containing the song, etc.) included in the set list by the application 151. It may be possible to purchase on the spot (so-called “net purchase”). By having such a function, it is expected to contribute to sales promotion by the exhilaration of a live concert. Also, in the case of a song that the audience does not know, it can be purchased on the spot, so that it can be prevented that the song cannot be purchased without being able to remember the song later.

  Next, the storage unit 153 will be described. The storage unit 153 stores the history of images displayed on the screen 210 (particularly, images displayed in the second display state) as session data. For example, when the corresponding image display terminal 200 is connected to the network 140, the session data stored in the storage unit 153 is transmitted to the data server 160 via the network 140 and stored in the data server 160.

  Each connection device 150 transmits its own session data to the other connection device 150, and conversely, receives and stores session data from the other connection device 150. That is, each connection device 150 stores session data of all connection devices 150 including itself. Thereby, the session data of all the connected devices 150 can be shared by all the connected devices 150. For example, there may be a case where part or all of the session data is not saved (updated) in the data server 160 for some reason. In such a case, session data shared by each connection device 150 is used to prove each other, thereby supplementing (restoring) the session data that could not be saved (updated) on the data server 160. can do. Therefore, the session data of each connected device 150 can be stored in the data server 160 more reliably.

  Further, in the image display system 100, after the live concert is finished, the audience may be able to watch a moving image based on the session data. Specifically, by accessing the data server 160 from a communication terminal such as a smartphone or a PC on the day after the live concert, the same image as the image selected using the image display terminal 200 can be viewed during the live concert. It may be. At this time, the image display system 100 can reproduce an image based on the session data stored in the data server 160. Note that the image provided here preferably includes sound synchronized with the image. As mentioned above, during a live concert, it is preferable that the image does not contain sound in order to enjoy a sense of reality, but conversely, the image that is viewed after the end of the live concert is more likely to contain sound. A sense of reality increases.

  Thus, if the image can be reviewed, it can be enjoyed after the live concert, such as remembering the excitement of the live concert. At this time, it is preferable that the connection device 150 used in the live concert functions as an access key. That is, for example, it is preferable that access to the data server 160 from a communication terminal other than the communication terminal to which the connection device 150 is connected is restricted. Accordingly, since only the owner of the connection device 150 can access the data server 160, it is possible to prevent a problem that an unspecified number of users are accessed (images are seen). For example, even if the connection device 150 is not connected, the data server 160 may be accessed by inputting a predetermined ID, password, etc. In this case, the ID and password are obtained. Then, anyone can access the data server 160. From this point, stricter security can be established by using the connection device 150 as an access key.

  Next, the battery 154 will be described. The battery 154 functions not only as a power source for the connection device 150 (power source for driving the application 151) but also as a standby power source for the image display terminal 200. If the image display terminal 200 is used for a long time during a live concert, a considerable amount of power is consumed, and the power source of the image display terminal 200 may not be held until the end of the live concert. Therefore, by installing the battery 154 that can function as a standby power source for the image display terminal 200, it is possible to reduce the power of the image display terminal 200 from being cut off during the live concert as described above. .

  Note that the battery 154 may be omitted. In this case, contrary to the present embodiment, the connection device 150 may be driven by supplying power from a battery built in the image display terminal 200. Regardless of whether the battery 154 is built-in or omitted, a connection unit (external battery) connected to the connection device 150 is separate from the connection device 150 and the image display terminal 200 ( A connector) is preferably provided. Thereby, for example, an external battery which is the property of the audience can be connected to the connection device 150, and this external battery can be used as a power source or a standby power source for the connection device 150 or the image display terminal.

  Next, the connector 155 will be described. The connector 155 has a function of electrically connecting the connection device 150 to the image display terminal 200. Therefore, the connector 155 has a structure (standard) that can be connected to the image display terminal 200.

  Here, in particular, when an image display terminal 200 is used by an individual audience, it is assumed that the OS (operating system) and the connector differ depending on the manufacturer of the image display terminal 200 and the like. Specific examples of smartphones based on the current situation include, for example, “iOS” provided by Apple Inc. and “android” (registered trademark) provided by Google Inc. are widely used as the OS. The “Lighting connector” used in a model equipped with an iOS and the “MicroUSB connector” used in a model equipped with an Android are widely used.

  Therefore, for example, the connection device 150 for the iOS terminal and the connection device 150 for the Android terminal may be prepared separately. For example, each connection device 150 may include an application for iOS and an application for Android as the application 151, and may further include a Lightning connector and a MicroUSB connector as the connector 155.

  Further, for example, as shown in FIG. 13, a conversion connector 180A for converting the connection device 150 for an iOS terminal and a conversion connector 180B for converting the connection device 150 for an Android terminal are provided. The connection device 150 may be connected to the image display terminal 200 via 180B. In this case, the conversion connectors 180A and 180B may include a conversion program for converting the application 151 for iOS or Android, a battery, and the like as necessary.

  According to each of these methods, it is possible to obtain the connection device 150 that can handle each of the different types of image display terminals 200 relatively easily. Note that the above description is merely a specific example for convenience of explanation, and the type of OS or connector is not particularly limited.

  The connection device 150 has been described above. However, the configuration of the connection device 150 is not particularly limited. For example, in addition to the functions described above, various functions can be mounted as necessary. For example, the connection device 150 may have a beacon function. Thereby, for example, when a beacon oscillator is installed in a concert venue and the connection device 150 receives the beacon, it automatically excites some action (for example, display of various information on the screen 210). Can do.

  The basic configuration of the image display system 100 has been described above. Next, a specific usage example of the image display system 100 will be described with an example of the live concert of the idol group X described above.

  For example, it is assumed that a spectator using a certain image display terminal 200 (the image display terminal 200 to which the connection device 150 is connected) is a fan of member A of the idol group X. In such a case, the spectator checks the screen 210 in the first display state, and selects an image in which the member A is shown from a plurality of images, thereby displaying an image in which the member A is shown on the main screen. This image can be enlarged and displayed as the second display state. For this reason, while watching the live concert with the naked eye, in addition to this, the user can further enjoy the live concert by watching the image on the image display terminal 200.

  In addition, for example, among many audiences, there is an audience who knows well what kind of pose determines which member at what timing of which song and wants to see that pose. In such a case, in accordance with the timing, the member who determines the pose selects the image shown at the best angle and displays it in the full screen display (second display state). You can appreciate the pose clearly. In this way, the function of switching images according to the audience's own desire is also referred to as “selection function”.

  Here, the connection device 150C for the audience that is a fan of the member A and the connection device 150D for the audience that is a fan of the member B are distinguished, and the image display terminal 200C to which the connection device 150C is connected is mainly used. The image showing the member A may be distributed to the image display terminal 200D to which the connection device 150D is connected, and the image mainly showing the member B may be distributed. In other words, different images may be distributed to the plurality of image display terminals 200 according to the user's attributes. According to such a configuration, since the image is displayed on the image display terminal 200 so as to track the members who are fans (because it is possible to deliver an image that meets the needs of each spectator), the audience will You can enjoy more live concerts. Thus, the function of displaying an image for tracking a specific member on the image display terminal 200 is also referred to as a “tracking function”.

  In this case, as illustrated in FIG. 14, the image generation unit 120 selects the image in which the member A is shown from the plurality of images acquired by the image acquisition unit 110 and generates a multi-image MS for the connected device 150C. A generation unit 121, and a member B generation unit 122 that selects an image in which member B is shown from a plurality of images acquired by the image acquisition unit 110 and generates a multi-image MS for the connected device 150D. doing. Further, the distribution unit 130 encodes the multi-image MS generated by the member A generation unit 121 as one image for live streaming, and performs streaming distribution to the image display terminal 200C (parent node) via the network 140. The member B for encoding the multi-image MS generated by the distribution unit 131 and the member B generation unit 122 as a single image for live streaming and streaming distribution to the image display terminal 200D (parent node) via the network 140 And a distribution unit 132.

  In the above description, the connection device 150 (150C, 150D) having a different setting is used to distinguish whether the fan is the member A fan or the member B fan. 150, members whose fans are fans can be selected using the image display terminal 200.

  Heretofore, an example of a specific usage example of the image display system 100 has been described. According to such an image display system 100, a live concert that can be enjoyed by each person can be held. In particular, in the present embodiment, since the “selection function” and the “tracking function” are combined, a live concert and the like that can be enjoyed by each person can be held.

  Next, further functions of the image display system 100 will be described. The functions described above were functions for the audience side, but the functions described below can be said to be functions for the organizer side.

  First, the image display system 100 has a totaling function. Specifically, the image display system 100 includes a counting unit that counts and stores in real time which images are displayed in the second display state in the plurality of image display terminals 200. Which image is displayed in the second display state can be specified using, for example, session data. For example, as shown in FIG. 15, which image is displayed in the second display state in the plurality of image display terminals 200 is stored in the counting unit in real time together with the time. The data stored in the counting unit can be used as follows.

  For example, an image that is often displayed in the second display state can be assumed to be a more popular image. Therefore, an image that is most frequently displayed in the second display state (hereinafter referred to as “popular image”). Is the main image of the multi-image displayed in the first display state. Thus, by making the more popular image the main image, it becomes easier for the audience to find the image, and an image that better meets the needs can be effectively provided to the audience. The timing for switching the popular image to the main image is not particularly limited. For example, when switching from the second display state to the first display state, the selection of the main screen in the first display state has elapsed for a predetermined time or more. However, it could be when it was not implemented.

  Further, for example, the data aggregated by the aggregation unit can be used to select an image to be displayed on the screen, such as displaying a popular image on the screen. In addition, for example, for those who cannot purchase tickets or who live far away and cannot participate in live concerts, in recent years, live broadcasts have been planned in movie theaters. In such an event, the data aggregated by the aggregation unit can be used to select the video to be displayed on the screen.

  Further, the data aggregated by the aggregation unit can be used as a reference when producing recording media (including download-type programs) such as DVDs and BDs that record live concerts at a later date. For example, by using a lot of popular images, it is possible to produce a recording medium that better meets the needs of the buyer.

  The summary function of the image display system 100 has been described above. In addition, the above-mentioned total may be totaled from all the image display terminals 200, or may be totaled from some arbitrarily selected image display terminals 200. In addition, when counting from a part of the image display terminals 200, the image display terminals 200 may be selected at random or may be selected with a certain degree of regularity.

For example, how to use the application 151, CM (commercial message) of a sponsoring company, introduction of past live DVDs, directions to the nearest station of the venue, and when returning Examples include traffic congestion. Further, for example, the product introduced in the image P10 may be purchased on the spot (so-called online purchase) using the image display terminal 200. Note that the image P10 is preferably not displayed in the second display state.

  Third, the image display system 100 has a billing function. Specifically, for example, if a predetermined amount is paid, all or a part of the image displayed on the image display terminal 200 can be recorded, and the stored data can be transferred and stored in, for example, his / her smartphone or the like. Functions. However, such a function is provided on the assumption that various problems of the copyright law are solved.

  Fourth, the image display system 100 has a participation function that allows a spectator to participate live. As a result, the organizer can accumulate marketing data and can effectively use the marketing data for future activities. In addition, the consciousness of the audience to participate in the live concert can be enhanced, and each audience can enjoy the live concert more, and the concert venue can become more integrated, resulting in a better live concert.

  An example of such a participation function is a questionnaire function. This is a function that allows the audience to answer a questionnaire using the image display terminal 200. Thereby, the organizer can accumulate more effective marketing data. In order to increase the collection rate of the questionnaire, for example, the application 151 may be configured so that an image of a live concert can be viewed only after the questionnaire is answered. The contents of the questionnaire are not particularly limited and vary depending on the contents of the event, but in the example of this embodiment, for example, demographic information such as age, gender, birthplace, current address, etc., participation frequency in live concerts, fans Preference information such as the names of members. The totaling result of the information may be displayed as a graph (for example, a pie chart or a bar chart) on a screen in the hall. In addition, for example, after the live concert, the impression of the live concert may be collected in a questionnaire format using the image display terminal 200.

  An example of the participation function is a voting function. This is a function that allows the audience to vote using the image display terminal 200. Thereby, the organizer can accumulate more effective marketing data. The content of the vote is not particularly limited and varies depending on the content of the event, but in the example of this embodiment, the song that you want to sing in the encore, the taste of the song (original version, acoustic version, classic version, etc.), the entertainment you want to do Etc. For example, by voting a song desired to be sung by encore among a plurality of pre-selected songs and singing the song having the highest number of votes by encore, the venue can be further excited.

  Moreover, as a participation function, a lottery function is mentioned, for example. This is a function in which a prize or the like is presented to a spectator using a specific image display terminal 200. According to such a function, it is possible to make the venue more exciting. The present is not particularly limited, and examples include live original goods and goods signed by members.

  Moreover, as a participation function, a message transmission function is mentioned, for example. This is a function that enables the audience to send a message using the image display terminal 200. For example, a message transmitted using the image display terminal 200 is displayed on the screen, and members A and B of the idol group X respond to the message, thereby allowing the idol group X and the audience to respond. Conversations are established and live concerts can be more exciting.

  Moreover, as a participation function, a game function is mentioned, for example. This is a function that allows the audience to participate in the game using the image display terminal 200. This can make live concerts more exciting. The game is not particularly limited, and examples include a bingo game, a janken game with the idol group X, and a quiz (particularly, a quiz related to the idol group X).

  Fifth, the image display system 100 has a point addition function. This is a function in which points are added each time a particular live concert is participated and can be exchanged for various types of prizes according to the number of points acquired. By adopting such a point system, the audience can be more satisfied. The point addition mechanism is not particularly limited. For example, if the application 151 is activated, a point may be automatically added, or the point addition mechanism may be installed at a specific place in the live concert.
