Modes for Carrying Out the Invention

[0019] Hereinafter, an example of an embodiment of the present invention will be described in detail. In the following description, specific shapes, materials, directions, numerical values, etc. are examples for facilitating the understanding of the present invention and can be appropriately changed according to applications, purposes, specifications, etc.

[0020] <1. Remote Video Distribution System> With reference to FIGS. 1 and 2, a remote video distribution system 10 which is an example of an embodiment will be described.

[0021] As shown in FIG. 1, the remote video distribution system 10 includes a plurality of display devices 11 provided in the car compartment 21 or the landing 22 of the elevator 20 and configured to display content to users, and a remote video distribution server 50 that distributes content to each display device 11 via a communication line 12. According to the remote video distribution system 10, although details will be described later, it is possible to maintain the quality of the content distribution service to elevator 20 users while reducing communication costs.

[0022] The elevator 20 of this embodiment is a passenger elevator mainly for transporting passengers. The building 13 in which the elevator 20 of this embodiment is installed includes apartment buildings, offices, commercial facilities, accommodation facilities, medical facilities, etc.

[0023] The display device 11 displays the content distributed from the remote video distribution server 50. The content is the content of information based on video data and includes advertisements, news, weather forecasts, etc. The advertisement may be an advertisement of a tenant in the commercial facility when the elevator 20 is installed in the commercial facility. Also, the advertisement may be a CM broadcast on a general TV.

[0024] In the remote video distribution system 10 of this embodiment, a configuration having a plurality of display devices 11 is adopted, but a configuration having only one display device 11 may also be used. The display device 11 of this embodiment includes a car display device 30 and a landing display device 40. Hereinafter, when referring to both the car display device 30 and the landing display device 40, it is simply described as the display device 11.

[0025] The car display device 30 is provided in the car 21 of the elevator 20. The car display device 30 displays the content for the passengers in the car 21. Details of the car display device 30 will be described later. The landing display device 40 is provided at the landing 22 of the elevator 20. The landing display device 40 displays the content for the passengers waiting for the elevator at the landing 22. Details of the landing display device 40 will be described later.

[0026] The remote video distribution server 50 distributes the content to the display devices 11 provided in each of the plurality of elevators 20 via the communication line 12. The remote video distribution server 50 of this embodiment is owned by the management company of the elevator 20. The remote video distribution server 50 of this embodiment distributes the content to the display devices 11 of the elevators 20 installed in each of the plurality of buildings 13. Details of the remote video distribution server 50 will be described later.

[0027] The communication line 12 connects the remote video distribution server 50 and a plurality of display devices 11. The communication line 12 in the present embodiment is a general communication line and includes a telephone line, a data communication line, and an Internet line.

[0028] By the way, as a usage fee pattern of the communication line 12, within a predetermined period, when the data communication volume is less than or equal to the basic data communication volume, the fee is uniform, and when the data communication volume exceeds the basic data communication volume, the data communication speed may decrease or the usage fee may increase. Therefore, a predetermined data communication volume is set as a data communication volume lower than the basic data communication volume, and when the data communication volume exceeds the predetermined data communication volume, measures such as stopping the distribution of low-priority content and reducing the distribution frequency of content are taken to reduce the communication cost. However, if an attempt is made to reduce the communication cost, the quality of the service provided to the passengers of the elevator 20 will deteriorate.

[0029] Therefore, in the remote video distribution system 10 of the present embodiment, although details will be described later, by calculating the distribution effect of the content of each display device 11 and reducing the data communication volume to the display device 11 with a low distribution effect, it is possible to maintain the quality of the content distribution service to the passengers of the elevator 20 while reducing the communication cost.

[0030] <2. Elevator> As shown in FIG. 2, the elevator 20 has an elevator control device 23, a car display device 30, and a landing display device 40, the details of which will be described later. In the present embodiment, the elevator 20 is configured to have the car display device 30 and the landing display device 40, but is not limited thereto. The elevator 20 may be configured to have at least one of the car display device 30 or the landing display device 40.

[0031] The elevator control device 23 controls the operation and speed of the car 21 of the elevator 20. The elevator control device 23 is connected to the car display device 30 and the landing display device 40. Further, a human presence sensor 25 for detecting the presence or absence of passengers in the car 21 and a human presence sensor 26 for detecting the presence or absence of passengers waiting for car allocation at the landing 22 are connected to the elevator control device 23.

[0032] In this embodiment, the human presence sensor 25 is configured to detect the presence or absence of passengers in the car 21, but it is not limited to this. For example, it may be configured to detect the presence or absence of passengers in the car 21 by an ultrasonic sensor, a photoelectric sensor, analysis of a photographed image by a camera, a car weighing device, or the lighting state of the destination buttons in the car.

[0033] In this embodiment, the human presence sensor 26 is configured to detect the presence or absence of passengers at the landing 22, but it is not limited to this. For example, it may be configured to detect the presence or absence of passengers at the landing 22 by an ultrasonic sensor, a photoelectric sensor, analysis of a photographed image by a camera, or the lighting state of the destination buttons at the landing.

[0034] <3. Display Device> As described above, the display device 11 includes the car display device 30 and the landing display device 40. As shown in FIG. 2, the car display device 30 displays the content distributed from the remote video distribution server 50 via the communication line 12. The car display device 30 has a network interface 31 connectable to the communication line 12 and a display unit 32 for displaying the distributed content.

[0035] As shown in FIG. 2, the landing display device 40 displays the content distributed from the remote video distribution server 50 via the communication line 12. The landing display device 40 has a network interface 41 connectable to the communication line 12 and a display unit 42 for displaying the distributed content.

[0036] <4. Remote Video Distribution Server> As shown in FIG. 2, the remote video distribution server 50 distributes content to a plurality of display devices 11 via a communication line 12. The remote video distribution server 50 is a computer having a processor 51 with a CPU that performs information processing, a memory 52 that stores software, programs, or data executed by the processor 51, and a network interface 53 connectable to the communication line 12.

[0037] As shown in FIG. 3, the remote video distribution server 50 has a data traffic calculation unit 61, a distribution effect calculation unit 62, and a data traffic control unit 63, the details of which will be described later. The data traffic calculation unit 61, the distribution effect calculation unit 62, and the data traffic control unit 63 are realized by the processor 51 executing a program stored in the memory 52.

[0038] <4-1. Data Traffic Calculation Unit> The data traffic calculation unit 61 calculates the data traffic of the communication line 12. More specifically, the data traffic calculation unit 61 calculates the data traffic of the communication line 12 in a predetermined period. Here, the data traffic is the sum of the data traffic between all the display devices 11 of the remote video distribution system 10 and the remote video distribution server 50. Also, the predetermined period is a delimiting period for determining the usage fee in the usage fee pattern of the communication line 12, for example, one month.

[0039] <4-2. Distribution Effect Calculation Unit> The distribution effect calculation unit 62 calculates the distribution effect of the content by each display device 11. The distribution effect calculation unit 62 of the present embodiment calculates the distribution effect based on the presence or absence of users in the car compartment 21 or the boarding area 22.

[0040] The distribution effect calculation unit 62 uses the ratio of the time that a user is present in the car cabin 21 during the time when the content is being displayed by the car cabin display device 30 as the distribution effect. When the ratio is high, the distribution effect is high; when the ratio is low, the distribution effect is low. The time that a user is present in the car cabin 21 is calculated based on the time when the human presence sensor 25 described above detects the presence of a user in the car cabin 21.

[0041] Also, the distribution effect calculation unit 62 uses the ratio of the time that a user is present in the landing 22 during the time when the content is being displayed by the landing display device 40 as the distribution effect. When the ratio is high, the distribution effect is high; when the ratio is low, the distribution effect is low. The time that a user is present in the landing 22 is calculated based on the time when the human presence sensor 26 described above detects the presence of a user in the landing 22.

[0042] As another example of the embodiment, the distribution effect calculation unit 62 may calculate the distribution effect of the content based on the number of users in the car cabin 21 or the landing 22.

[0043] For example, the distribution effect calculation unit 62 may use the number of users in the car cabin 21 during the time when the content is being distributed by the car cabin display device 30 as the distribution effect. Specifically, the product of the time when the content is being distributed and the number of users may be calculated as the distribution effect. The larger the product, the higher the distribution effect; the smaller the product, the lower the distribution effect. The number of users in the car cabin 21 may be calculated by photographing the users in the car cabin 21 with a camera provided in the car cabin 21 and analyzing the photographed image.

[0044] Further, the distribution effect calculation unit 62 may use the number of passengers waiting for the elevator at the boarding area 22 during the time when the content is being distributed by the boarding area display device 40 as the distribution effect. Specifically, the product of the time when the content is being distributed and the number of passengers may be calculated as the distribution effect. The greater the product, the higher the distribution effect, and the smaller the product, the lower the distribution effect. The number of passengers in the boarding area 22 may be calculated by photographing the passengers in the boarding area 22 with a camera provided in the boarding area 22 and analyzing the photographed image.

[0045] Note that the means for calculating the number of passengers in the elevator 20 is not limited to analyzing the image photographed by the camera provided in the car cabin 21 or the boarding area 22, and may be calculated based on the registration history of the destination prediction system or the weighing device of the car. The destination prediction system is a system that guides users to the same destination floor to the same elevator 20 by registering the destination floor before boarding, thereby making the operation more efficient.

[0046] As another example of the embodiment, the distribution effect calculation unit 62 may indirectly confirm whether the passenger has viewed the content and calculate the distribution effect of the content.

[0047] For example, in a system where the elevator 20 and the passenger's smartphone are linked, when the content displayed on the display device 11 is linked to the content of the smartphone, it may be calculated that the distribution effect of the display device 11 with fewer clicks on the smartphone content is low, and the distribution effect of the display device 11 with more clicks on the smartphone content is high.

[0048] Further, the distribution effect calculation unit 62 may calculate the distribution effect of the content based on the number of times the QR code (registered trademark) displayed on the display device 11 by the passengers in the car cabin 21 or the boarding area 22 is read. For example, it may be calculated that the distribution effect of the display device 11 with fewer reads of the QR code is low, and the distribution effect of the display device 11 with more reads of the QR code is high.

[0049] As another example of the embodiment, the distribution effect calculation unit 62 may calculate the distribution effect of the content based on the operation rate of the elevator 20. For example, the distribution effect calculation unit 62 may calculate that the distribution effect is low for the display device 11 of the elevator 20 with a low operation rate, and may calculate that the distribution effect is high for the display device 11 of the elevator 20 with a high operation rate. Further, the distribution effect calculation unit 62 may total the operation rate of the elevator 20 for each time period, calculate that the distribution effect is low for the time period with a low operation rate, and calculate that the distribution effect is high for the time period with a high operation rate.

[0050] As another example of the embodiment, the distribution effect calculation unit 62 may calculate the distribution effect of the content based on the number of times the content is displayed or the display time. Here, in the display device 11, in addition to the display of normal content, interrupt content related to the operation of the elevator 20 may be displayed. The interrupt content includes, for example, warning content regarding the usage status of the elevator 20, enlightenment content on the usage method according to the attributes of the user, and the like.

[0051] For example, it may be calculated that the distribution effect is low for the display device 11 of the elevator 20 where there is a lot of interrupt content and the number of times or display time of normal content is small. Also, it may be calculated that the distribution effect is high for the display device 11 of the elevator 20 where there is little interrupt content and the number of times or display time of normal content is large.

[0052] As another example of the embodiment, the distribution effect calculation unit 62 may calculate the distribution effect of the content based on the time when the users in the car compartment 21 or the landing 22 view the display device 11. For example, it may be calculated that the distribution effect is low for the display device 11 of the elevator 20 where the time when the user views the display device 11 is short, and it may be calculated that the distribution effect is high for the display device 11 of the elevator 20 where the time when the user views the display device 11 is long. The time of viewing the display device 11 may be calculated by analyzing the image captured by the camera provided in the car compartment 21 or the landing 22 and detecting the line of sight of the user.

[0053] <4-3. Data traffic control unit> When the data traffic exceeds the first data traffic within a predetermined period, the data traffic control unit 63 reduces the data traffic to the display device 11 with a low distribution effect calculated by the distribution effect calculation unit 62. Here, the first data traffic is set lower than the basic data traffic described above. As means for reducing the data traffic, it is preferable to reduce the number or types of contents to be distributed, reduce the data size of the contents to be distributed, stop the distribution of contents with low priority, reduce the distribution frequency of the contents, change the encoding specifications or conditions of the contents to be distributed, and the like.

[0054] Thereby, when the data traffic exceeds the first data traffic and there is no margin up to the basic data traffic, the distribution effect of the content of each display device 11 is calculated, and the data traffic to the display device 11 with a low distribution effect is reduced, whereby the communication cost can be reduced. In addition, since the data traffic to the display device 11 with a low distribution effect of the content is reduced, the quality of the content distribution service to the users of the elevator 20 is not impaired.

[0055] On the other hand, when the data traffic is less than the second data traffic within a predetermined period, the data traffic control unit 63 increases the data traffic to the display device 11 with a high distribution effect calculated by the distribution effect calculation unit 62. As means for increasing the data traffic, it is preferable to increase the number or types of contents to be distributed, increase the data size of the contents to be distributed, increase the distribution frequency of the contents, change the encoding specifications or conditions of the contents to be distributed, and the like. The second data traffic is an amount less than the first data traffic.

[0056] Thereby, when the data traffic is less than the second data traffic and there is a margin up to the basic data traffic, by calculating the distribution effect of the contents of each display device 11 and increasing the data traffic to the display device 11 with a high distribution effect, the quality of the content distribution service to the users of the elevator 20 can be improved.

[0057] The data traffic control unit 63 of the present embodiment is configured to decrease the data traffic to the display device 11 with a low distribution effect calculated by the distribution effect calculation unit 62 when the data traffic becomes equal to or more than the second data traffic within a predetermined period, and increase the data traffic to the display device 11 with a high distribution effect calculated by the distribution effect calculation unit 62 when the data traffic is less than the predetermined data traffic. However, a configuration that only decreases the data traffic to the display device 11 with a low distribution effect may be used, or a configuration that increases the data traffic to the display device 11 with a high distribution effect may be used.

[0058] As another example of the embodiment, as means for decreasing the data traffic, the data traffic control unit 63 may provide a memory in the display device 11, save the contents previously distributed by the remote video distribution server 50 in the memory, and distribute the contents saved in the memory. In this case, it is preferable to distribute and save the contents by the remote video distribution server 50 while there is a margin in the data traffic.

[0059] As another example of the embodiment, when a disaster occurs, the data traffic control unit 63 may increase the data traffic to the display device 11 of the building 13 in the disaster-stricken area and decrease the data traffic to the display device 11 of the building 13 in other areas. Thereby, the data traffic in the disaster area during a disaster can be ensured.

[0060] <5. Data Traffic Control> The flow of data traffic control of the remote video distribution system 10 will be described with reference to FIG. 4.

[0061] As shown in FIG. 4, in step S11, the data traffic calculation unit 61 of the remote video distribution server 50 starts adding up the data traffic of the entire remote video distribution system 10. In step S12, it is confirmed whether the data traffic of the entire remote video distribution system 10 is equal to or greater than the first data traffic. If it is equal to or greater than the first data traffic, since there is no margin up to the basic data traffic, the process proceeds to step S13. If it is less than the first data traffic, the process proceeds to step S15.

[0062] In step S13, the distribution effect calculation unit 62 of the remote video distribution server 50 calculates the distribution effect of the content of each display device 11 of the remote video distribution system 10. In step S14, the data traffic control unit 63 of the remote video distribution server 50 decreases the data traffic to the display device 11 with a low distribution effect and proceeds to step S18.

[0063] In step S15, it is checked whether the data traffic volume of the entire remote video distribution system 10 is less than the second data traffic volume. If it is less than the second data traffic volume, since there is a margin up to the basic data traffic volume, the process proceeds to step S16. If it is equal to or greater than the second predetermined data traffic volume, the process proceeds to step S18 (specifically, it is set to the normal mode without decreasing or increasing the data traffic volume). In step S16, the distribution effect calculation unit 62 of the remote video distribution server 50 calculates the distribution effect of the content of each display device 11 of the remote video distribution system 10. In step S17, the data traffic volume control unit 63 of the remote video distribution server 50 increases the data traffic volume to the display device 11 with a high distribution effect and proceeds to step S18.

[0064] In step S18, the data traffic volume calculation unit 61 of the remote video distribution server 50 checks whether a predetermined period has elapsed. If the predetermined period has elapsed, the process proceeds to step S19. In step S19, the data traffic volume calculation unit 61 of the remote video distribution server 50 resets the data traffic volume.

[0065] <6. Effect> According to the remote video distribution system 10, it is possible to maintain the quality of the content distribution service to the users of the elevator 20 while reducing the communication cost. More specifically, when the data traffic volume is equal to or greater than the first data traffic volume set lower than the basic data traffic volume where the so-called fee is uniform, by reducing the data traffic volume to the display device 11 with a low content distribution effect, it is made so as not to exceed the basic data traffic volume as much as possible. Thereby, the communication cost can be reduced. Also, since the data traffic volume to the display device 11 with a low content distribution effect is reduced, the quality of the content distribution service to the users of the elevator 20 is not impaired.

[0066] Also, when the data traffic volume is less than the second data traffic volume, since there is a margin until exceeding the basic data traffic volume, by increasing the data traffic volume to the display device 11 with a high content distribution effect, the quality of the content distribution service can be improved.

[0067] Note that the present invention is not limited to the above-described embodiments and their modifications, and it goes without saying that various changes and improvements can be made within the scope of the matters described in the claims of this application.
