[0027] In the following description, specific shapes, materials, directions, numerical values, etc. are exemplified to facilitate understanding of the present invention and can be appropriately changed according to application, purpose, specification, etc.

[0028] <1. Remote Image Distribution System>

[0029] use Figure 1 and Figure 2 , a remote image distribution system 10 as an example of an implementation method is described.

[0030] like Figure 1As shown, the remote image distribution system 10 includes: a plurality of display devices 11, which are installed in the elevator car room 21 or the landing 22 of the elevator 20 and display content to passengers; and a remote image distribution server 50, which distributes content to each display device 11 via a communication line 12. According to the remote image distribution system 10, the quality of the content distribution service for the passengers of the elevator 20 can be maintained while reducing the communication cost, and the details will be described later.

[0031] The elevator 20 of this embodiment is a passenger elevator, and its main purpose is to transport passengers. The building 13 in which the elevator 20 of this embodiment is installed includes a residential building, an office building, a commercial facility, an accommodation facility, a medical facility, and the like.

[0032] The display device 11 displays the content published from the remote video publishing server 50. The content is information based on video data, including advertisements, news, weather forecasts, etc. In the case where the elevator 20 is installed in a commercial facility, the advertisement may also be an advertisement of a tenant in the commercial facility. In addition, the advertisement may also be a CM broadcast on a general TV.

[0033] In the remote image distribution system 10 of the present embodiment, a plurality of display devices 11 are provided, but it is also possible to provide only one display device 11. The display device 11 of the present 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, only the display device 11 is recorded.

[0034] The car room display device 30 is installed in the car room 21 of the elevator 20. The car room display device 30 displays content to passengers in the car room 21. The details of the car room display device 30 will be described later. The landing display device 40 is installed in the landing 22 of the elevator 20. The landing display device 40 displays content to passengers waiting for the elevator at the landing 22. The details of the landing display device 40 will be described later.

[0035] The remote image distribution server 50 distributes content to the display devices 11 respectively installed in the plurality of elevators 20 via the communication line 12. The remote image distribution server 50 of this embodiment is owned by the management company of the elevators 20. The remote image distribution server 50 of this embodiment distributes content to the display devices 11 respectively installed in the plurality of elevators 20 of the buildings 13. The remote image distribution server 50 will be described in detail later.

[0036] The communication line 12 connects the remote video distribution server 50 and the plurality of display devices 11. The communication line 12 of the present embodiment is a general communication line, including a telephone line, a data communication line, and an Internet line.

[0037] In addition, as a usage fee model of the communication line 12, within a specified period, when the data communication volume is less than the basic data communication volume, the fee is fixed, and when the data communication volume exceeds the basic data communication volume, there is a case where the data communication speed is reduced or the usage fee is increased. Therefore, the specified data communication volume is set to a data communication volume lower than the basic data communication volume, and when the data communication volume exceeds the specified data communication volume, the communication cost is reduced by measures such as stopping the release of low-priority content and reducing the frequency of content release. However, if the communication cost is to be reduced, the service quality provided to the passengers of the elevator 20 will be reduced.

[0038] Therefore, in the remote image distribution system 10 of this embodiment, the distribution effect of the content of each display device 11 is calculated and the data communication volume for the display device 11 with low distribution effect is reduced, thereby reducing the communication cost while maintaining the quality of the content distribution service for the passengers of the elevator 20. The details will be described later.

[0039] <2. Elevator>

[0040] like Figure 2 As shown, the elevator 20 has an elevator control device 23, a car room display device 30, and a landing display device 40, which will be described in detail later. In the present embodiment, the elevator 20 is configured to have the car room display device 30 and the landing display device 40, but is not limited thereto. The elevator 20 may also be a structure having at least one of the car room display device 30 and the landing display device 40.

[0041] The elevator control device 23 controls the operation and speed of the elevator car 21. The elevator control device 23 is connected to the car display device 30 and the landing display device 40. In addition, the elevator control device 23 is connected to a human body sensor 25 for detecting whether there are passengers in the car 21 and a human body sensor 26 for detecting whether there are passengers waiting for the elevator at the landing 22.

[0042] In this embodiment, the presence or absence of a passenger in the car room 21 is detected by the human body sensing sensor 25, but the present invention is not limited thereto. For example, the presence or absence of a passenger in the car room 21 may be detected by an ultrasonic sensor, a photoelectric sensor, analysis of a captured image obtained by a camera, a car scale device, or the lighting state of a destination button in the car.

[0043] In the present embodiment, the presence or absence of passengers at the landing 22 is detected by the human body sensing sensor 26, but the present invention is not limited thereto. For example, the presence or absence of passengers at the landing 22 may be detected by an ultrasonic sensor, a photoelectric sensor, analysis of a captured image obtained by a camera, or the lighting state of a landing destination button.

[0044] <3. Display device>

[0045] As described above, the display device 11 includes the car room display device 30 and the landing display device 40. Figure 2 As shown, the cage display device 30 displays the content distributed from the remote video distribution server 50 via the communication line 12. The cage display device 30 includes a network interface 31 connectable to the communication line 12 and a display unit 32 for displaying the distributed content.

[0046] like Figure 2 As shown, the hall display device 40 displays the content distributed from the remote video distribution server 50 via the communication line 12. The hall display device 40 includes a network interface 41 connectable to the communication line 12 and a display unit 42 for displaying the distributed content.

[0047] <4. Remote Image Publishing Server>

[0048] like Figure 2 As shown, the remote image distribution server 50 distributes content to a plurality of display devices 11 via the communication line 12. The remote image distribution server 50 is a computer having: a processor 51 having a CPU for information processing; a memory 52 storing software, programs or data executed by the processor 51; and a network interface 53 capable of connecting to the communication line 12.

[0049] like Figure 3 As shown, the remote video distribution server 50 includes a data communication volume calculation unit 61, a distribution effect calculation unit 62, and a data communication volume control unit 63, which will be described in detail later. The data communication volume calculation unit 61, the distribution effect calculation unit 62, and the data communication volume control unit 63 are implemented by the processor 51 executing a program stored in the memory 52.

[0050] <4-1. Data Communication Volume Calculation Unit>

[0051] The data communication volume calculation unit 61 calculates the data communication volume of the communication line 12. More specifically, the data communication volume calculation unit 61 calculates the data communication volume of the communication line 12 within a predetermined period. Here, the data communication volume refers to the total data communication volume of all display devices 11 of the remote image distribution system 10 and the remote image distribution server 50. In addition, the predetermined period refers to a segment period for determining the usage fee in the usage fee model of the communication line 12, for example, one month.

[0052] <4-2. Release effect calculation section>

[0053] The delivery effect calculation unit 62 calculates delivery effects of the content by each display device 11. The delivery effect calculation unit 62 of the present embodiment calculates delivery effects based on the presence or absence of passengers in the cage room 21 or the landing 22.

[0054] The publishing effect calculation unit 62 uses the ratio of the time when the passenger exists in the car room 21 to the time when the content is displayed by the car room display device 30 as the publishing effect. When the ratio is high, the publishing effect is high, and when the ratio is low, the publishing effect is low. The time when the passenger exists in the car room 21 is calculated based on the time when the human body sensing sensor 25 detects the presence of the passenger in the car room 21.

[0055] In addition, the publication effect calculation unit 62 uses the ratio of the time when there are passengers at the landing 22 to the time when the content is displayed by the landing display device 40 as the publication effect. When the ratio is high, the publication effect is high, and when the ratio is low, the publication effect is low. The time when there are passengers at the landing 22 is calculated based on the time when the human body sensing sensor 26 detects that there are passengers at the landing 22.

[0056] As another example of the embodiment, the delivery effect calculation unit 62 may calculate the delivery effect of the content based on the number of passengers in the car room 21 or the landing 22 .

[0057] For example, the publishing effect calculation unit 62 may also use the number of passengers in the car room 21 during the time when the content is published by the car room display device 30 as the publishing effect. Specifically, the product of the time when the content is published and the number of passengers may be calculated as the publishing effect. The larger the product, the higher the publishing effect, and the smaller the product, the lower the publishing effect. The number of passengers in the car room 21 may also be calculated by photographing the passengers in the car room 21 with a camera installed in the car room 21 and analyzing the photographed image.

[0058] In addition, the publishing effect calculation unit 62 may also use the number of passengers waiting for the elevator at the landing 22 during the time when the content is published by the landing display device 40 as the publishing effect. Specifically, the product of the time when the content is published and the number of passengers may be calculated as the publishing effect. The larger the product, the higher the publishing effect, and the smaller the product, the lower the publishing effect. The number of passengers at the landing 22 may also be calculated by photographing the passengers at the landing 22 with a camera installed at the landing 22 and analyzing the photographed image.

[0059] In addition, the number of passengers in the elevator 20 is not limited to the means of calculating by analyzing the image captured by the camera installed in the car room 21 or the landing 22, but can also be calculated by the registration history of the destination prediction system and the car scale device. The destination prediction system is a system that guides users of the same destination floor to the same elevator 20 by registering the destination floor before taking the elevator, thereby making the operation more efficient.

[0060] As another example of the embodiment, the distribution effect calculation unit 62 may calculate the distribution effect of the content by indirectly confirming whether the passenger has viewed the content.

[0061] For example, in a system in which the elevator 20 is linked to a passenger's smartphone, when the content displayed by the display device 11 is linked to the content of the smartphone, the display device 11 on which the passenger clicks the smartphone content fewer times can be calculated as having a low publishing effect, and the display device 11 on which the passenger clicks the smartphone content more times can be calculated as having a high publishing effect.

[0062] Furthermore, the publishing effect calculation unit 62 may also calculate the publishing effect of the content based on the number of times the QR code (registered trademark) displayed on the display device 11 is read by passengers in the car room 21 or the landing 22. For example, a display device 11 with a small number of QR code readings may be calculated as having a low publishing effect, and a display device 11 with a large number of QR code readings may be calculated as having a high publishing effect.

[0063] As another example of an implementation, the publishing effect calculation unit 62 may also calculate the publishing effect of the content based on the operation rate of the elevator 20. For example, the publishing effect calculation unit 62 may calculate the display device 11 of the elevator 20 with a low operation rate as having a low publishing effect, and may calculate the display device 11 of the elevator 20 with a high operation rate as having a high publishing effect. In addition, the publishing effect calculation unit 62 may add up the operation rate of each time period of the elevator 20, calculate the time period with a low operation rate as having a low publishing effect, and calculate the time period with a high operation rate as having a high publishing effect.

[0064] As another example of an implementation, the publishing effect calculation unit 62 may also calculate the publishing effect of the content based on the number of times the content is displayed or the display time. Here, in addition to the display of normal content, the display device 11 may also display interruption content related to the operation of the elevator 20. The interruption content may include, for example, warning content for the use status of the elevator 20, and content of disclosure of the use method based on the attributes of the user.

[0065] For example, the display device 11 of the elevator 20 with many interruption contents and few display times or display time of normal contents can be calculated as having low publishing effect. In addition, the display device 11 of the elevator 20 with few interruption contents and many display times or display time of normal contents can be calculated as having high publishing effect.

[0066] As another example of implementation, the publishing effect calculation unit 62 may also calculate the publishing effect of the content based on the time that the passenger in the car room 21 or the landing 22 views the display device 11. For example, the display device 11 of the elevator 20 in which the passenger views the display device 11 less time may be calculated as having a low publishing effect, and the display device 11 of the elevator 20 in which the passenger views the display device 11 more time may be calculated as having a high publishing effect. The viewing time of the display device 11 may also be calculated by analyzing an image captured by a camera installed in the car room 21 or the landing 22 and detecting the line of sight of the passenger.

[0067] <4-3. Data Traffic Control Unit>

[0068] When the data communication volume becomes equal to or greater than the first data communication volume within a predetermined period, the data communication volume control unit 63 reduces the data communication volume for the display device 11 having a low publishing effect calculated by the publishing effect calculation unit 62. Here, the first data communication volume is set to be lower than the above-mentioned basic data communication volume. As a means of reducing the data communication volume, it is preferred to reduce the number or types of published contents, reduce the data size of the published contents, stop publishing low-priority contents, reduce the publishing frequency of contents, change the specification or conditions of the encoding of the published contents, etc.

[0069] Thus, when the data communication volume becomes equal to or larger than the first data communication volume and there is no margin up to the basic data communication volume, the content delivery effect of each display device 11 is calculated, and the data communication volume for the display device 11 with low delivery effect is reduced, thereby reducing the communication cost. In addition, since the data communication volume for the display device 11 with low content delivery effect is reduced, the quality of the content delivery service for the passengers of the elevator 20 is not impaired.

[0070] On the other hand, when the data communication volume is less than the second data communication volume within the prescribed period, the data communication volume control unit 63 increases the data communication volume for the display device 11 having a high publishing effect calculated by the publishing effect calculation unit 62. As a means for increasing the data communication volume, it is preferable to increase the number or types of published contents, increase the data size of the published contents, increase the publishing frequency of the contents, change the specification or condition of the encoding of the published contents, etc. In addition, the second data communication volume is an amount less than the first data communication volume.

[0071] Therefore, when the data communication volume is less than the second data communication volume and there is a surplus until the basic data communication volume, the publishing effect of the content of each display device 11 is calculated, and the data communication volume for the display device 11 with a high publishing effect is increased, thereby improving the quality of the content publishing service for the passengers of the elevator 20.

[0072] The data communication volume control unit 63 of the present embodiment is configured to reduce the data communication volume for the display device 11 with a low publication effect calculated by the publication effect calculation unit 62 when the data communication volume is greater than the second data communication volume within a specified period, and to increase the data communication volume for the display device 11 with a high publication effect calculated by the publication effect calculation unit 62 when the data communication volume is less than the specified data communication volume. However, it may also be a structure that only reduces the data communication volume for the display device 11 with a low publication effect, or it may be a structure that increases the data communication volume for the display device 11 with a high publication effect.

[0073] As another example of implementation, the data communication volume control unit 63 may also provide a memory in the display device 11 as a means for reducing the data communication volume, store the content published by the remote image publishing server 50 in the memory in advance, and publish the content stored in the memory. In this case, it is preferred that the remote image publishing server 50 publishes and stores the content during a period when the data communication volume is sufficient.

[0074] As another example of implementation, the data communication volume control unit 63 may also increase the data communication volume for the display device 11 of the building 13 in the disaster-hit area and reduce the data communication volume for the display device 11 of the building 13 in other areas when a disaster occurs. In this way, the data communication volume in the disaster area during a disaster can be ensured.

[0075] <5. Data Traffic Control>

[0076] use Figure 4 , the process of data communication volume control of the remote image distribution system 10 is explained.

[0077] like Figure 4 As shown, in step S11, the data communication volume calculation unit 61 of the remote image distribution server 50 starts to add the data communication volume of the entire remote image distribution system 10. In step S12, it is confirmed whether the data communication volume of the entire remote image distribution system 10 is greater than the first data communication volume. If it is greater than the first data communication volume, since there is no surplus until the basic data communication volume, it is transferred to step S13. If it is less than the first data communication volume, it is transferred to step S15.

[0078] 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 communication volume control unit 63 of the remote video distribution server 50 reduces the data communication volume to the display device 11 with low distribution effect, and transfers to step S18.

[0079] In step S15, it is confirmed whether the data communication volume of the entire remote image distribution system 10 is less than the second data communication volume. If it is less than the second data communication volume, since there is a margin up to the basic data communication volume, the process proceeds to step S16. If it is greater than the second predetermined data communication volume, the process proceeds to step S18 (the data communication volume is not particularly reduced or increased, and is set to a normal mode). In step S16, the distribution effect calculation unit 62 of the remote image distribution server 50 calculates the distribution effect of the content of each display device 11 of the remote image distribution system 10. In step S17, the data communication volume control unit 63 of the remote image distribution server 50 increases the data communication volume for the display device 11 with a high distribution effect, and the process proceeds to step S18.

[0080] In step S18, the data communication volume calculation unit 61 of the remote video distribution server 50 checks whether a predetermined period has passed. If the predetermined period has passed, the process proceeds to step S19. In step S19, the data communication volume calculation unit 61 of the remote video distribution server 50 resets the data communication volume.

[0081] <6. Effect>

[0082] According to the remote video distribution system 10, it is possible to maintain the quality of the content distribution service for the passengers of the elevator 20 while reducing the communication cost. More specifically, when the data communication volume is equal to or greater than the first data communication volume set lower than the so-called basic data communication volume with a fixed fee, the data communication volume for the display device 11 with a low content distribution effect is reduced so as not to exceed the basic data communication volume as much as possible. In this way, the communication cost can be reduced. In addition, since the data communication volume for the display device 11 with a low content distribution effect is reduced, the quality of the content distribution service for the passengers of the elevator 20 is not impaired.

[0083] Furthermore, when the data communication amount is smaller than the second data communication amount, there is room to exceed the basic data communication amount, so the quality of content delivery service can be improved by increasing the data communication amount for display device 11 having a high content delivery effect.

[0084] In addition, the present invention is not limited to the above-mentioned embodiment and its modified examples, and various changes and improvements can be made within the scope of the matters described in the claims of the present application.
