Description

Elevator remote video distribution system

[0001] The present invention relates to a remote video distribution system having a display device installed in an elevator car or landing that displays content to passengers, and a video distribution server that distributes content to the display device via a communication line.

[0002] In some cases, a display device that displays content to passengers is provided in an elevator cab or landing. For example, Patent Document 1 discloses a technology that includes a plurality of display devices (displays) that are provided in an elevator cab or landing and that display content to passengers, and that distributes content (video information) to each display device via a communication line.

[0003] The communication lines mentioned above are generally telephone lines. The telephone line usage fee pattern is that, for a specified period of time, if the data traffic is less than a basic data traffic volume, a fixed fee is charged, and if the basic data traffic volume is exceeded, the communication speed may be reduced or the usage fee may be increased. Therefore, when the data traffic volume exceeds a predetermined data traffic volume, which is set lower than the basic data traffic volume, communication costs are reduced by taking measures such as stopping the distribution of low-priority content or reducing the frequency of content distribution.

[0004] Special Publication No. 2003-523002

[0005] However, if an attempt is made to reduce communication costs as described above, the quality of the content distribution service to elevator users will be reduced.

[0006] Therefore, an object of the present invention is to provide an elevator remote video distribution system that can maintain the quality of content distribution services to elevator users while reducing communication costs.

[0007] The remote video distribution system of the present invention is a remote video distribution system having a display device that is installed in an elevator car or landing and displays content to users, and a remote video distribution server that distributes content to the display device via a communication line, wherein the remote video distribution server is characterized by comprising a data communication volume calculation unit that calculates the data communication volume of the communication line for a predetermined period of time, a distribution effect calculation unit that calculates the distribution effect of the content by the display device, and a data communication volume control unit that reduces the data communication volume when the data communication volume for the predetermined period becomes equal to or greater than a first data communication volume and the distribution effect calculated by the distribution effect calculation unit is low.

[0008] According to the above configuration, when the distribution effect of the content of the display device is calculated and the distribution effect is low, the amount of data communication is reduced, thereby reducing communication costs without compromising the quality of the content distribution service to elevator users.

[0009] In the remote video distribution system of the present invention, it is preferable that the system has a plurality of display devices, and that the data communication volume control unit reduces the data communication volume to a display device having a low distribution effect calculated by the distribution effect calculation unit when the data communication volume for a specified period of time becomes equal to or greater than a first data communication volume.

[0010] According to the above configuration, by calculating the content distribution effectiveness of the display device and reducing the amount of data communication to the display device with low distribution effectiveness, communication costs can be reduced without compromising the quality of the content distribution service to elevator users.

[0011] The remote video distribution system of the present invention is a remote video distribution system having a display device that is installed in an elevator car or landing and displays content to users, and a remote video distribution server that distributes content to the display device via a communication line, wherein the remote video distribution server is characterized by comprising a data communication volume calculation unit that calculates the data communication volume of the communication line for a predetermined period of time, a distribution effect calculation unit that calculates the distribution effect of the content by the display device, and a data communication volume control unit that increases the data communication volume when the data communication volume for the predetermined period is less than a second data communication volume and the distribution effect calculated by the distribution effect calculation unit is high.

[0012] According to the above configuration, the distribution effectiveness of the content of the display device is calculated, and if the distribution effectiveness is high, the data communication volume can be increased to improve the quality of the content distribution service to elevator users.

[0013] In the remote video distribution system of the present invention, it is preferable that the system has a plurality of display devices, and that the data communication volume control unit increases the data communication volume to the display device having a high distribution effect calculated by the distribution effect calculation unit when the data communication volume for a specified period is less than a second data communication volume.

[0014] According to the above configuration, the quality of content distribution services to elevator users can be improved by calculating the content distribution effectiveness of the display device and increasing the amount of data communication to the display device with the highest distribution effectiveness.

[0015] In the remote video distribution system according to the present invention, it is preferable that the distribution effect calculation unit calculates the distribution effect of the content based on whether or not there are passengers using the elevator.

[0016] In the remote video distribution system according to the present invention, it is preferable that the distribution effect calculation unit calculates the distribution effect of the content based on the number of users of the elevator.

[0017] According to the elevator remote video distribution system of the present invention, it is possible to maintain the quality of the content distribution service to elevator users while reducing communication costs.

It is a block diagram showing the configuration of a remote video distribution system as an example of an embodiment. It is a block diagram showing the configuration of a remote video distribution server as an example of an embodiment. It is a flow diagram showing the flow of data communication amount control of a remote video distribution system as an example of an embodiment.

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

[0020] 1. Remote Video Distribution System A remote video distribution system 10 as an example of an embodiment will be described with reference to FIGS. 1 and 2. FIG.

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

[0022] The elevator 20 of this embodiment is a passenger elevator primarily intended 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 content distributed from the remote video distribution server 50. The content is information based on video data, and includes advertisements, news, weather forecasts, etc. If the elevator 20 is installed in a commercial facility, the advertisements may be advertisements for tenants in the commercial facility. The advertisements may also be commercials broadcast on regular TV.

[0024] Although the remote video distribution system 10 of this embodiment is configured to have a plurality of display devices 11, it may also be configured to have only one display device 11. The display devices 11 of this embodiment include a car display device 30 and a hall display device 40. Hereinafter, when referring to both the car display device 30 and the hall display device 40, they will be simply referred to 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 content to passengers in the car 21. Details of the car display device 30 will be described later. The hall display device 40 is provided in the hall 22 of the elevator 20. The hall display device 40 displays content to passengers waiting for a ride at the hall 22. Details of the hall display device 40 will be described later.

[0026] The remote video distribution server 50 distributes 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 a management company of the elevators 20. The remote video distribution server 50 of this embodiment distributes content to the display devices 11 of the elevators 20 provided in each of the plurality of buildings 13. The remote video distribution server 50 will be described in detail later.

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

[0028] Incidentally, as a usage fee pattern for the communication line 12, if the data communication volume during a predetermined period is equal to or less than the basic data communication volume, the fee may be flat, but if the data communication volume exceeds the basic data communication volume, the data communication speed may be reduced or the usage fee may be increased. For this reason, 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, communication costs are reduced by taking measures such as stopping the distribution of low-priority content or reducing the frequency of content distribution. However, attempts to reduce communication costs result in a decrease in the quality of service provided to users of the elevator 20.

[0029] Therefore, in the remote video distribution system 10 of this embodiment, as will be described in detail later, the content distribution effect of each display device 11 is calculated and the amount of data communication to display devices 11 with low distribution effect is reduced, thereby reducing communication costs while maintaining the quality of the content distribution service to passengers of the elevator 20.

[0030] 2, the elevator 20 has an elevator control device 23, which will be described in detail later, a car display device 30, and a hall display device 40. In this embodiment, the elevator 20 is configured to have the car display device 30 and the hall display device 40, but is not limited to this. The elevator 20 may also be configured to have at least one of the car display device 30 or the hall display device 40.

[0031] Elevator control device 23 controls the operation and speed of car 21 of elevator 20. Elevator control device 23 is connected to car display device 30 and hall display device 40. In addition, elevator control device 23 is connected to a human presence sensor 25 that detects the presence or absence of a passenger in car 21 and a human presence sensor 26 that detects the presence or absence of a passenger waiting at hall 22.

[0032] In this embodiment, the presence or absence of a passenger in the car room 21 is detected by the human presence sensor 25, but the present invention is not limited to this. 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 an image captured by a camera, a car weighing device, or the illuminated state of a destination button in the car.

[0033] In this embodiment, the presence or absence of a passenger at the hall 22 is detected by the human presence sensor 26, but the present invention is not limited to this. For example, the presence or absence of a passenger at the hall 22 may be detected by an ultrasonic sensor, a photoelectric sensor, analysis of an image captured by a camera, or the lighting state of a hall destination button.

[0034] 3. Display Device As described above, the display device 11 includes the car display device 30 and the hall display device 40. As shown in Fig. 2, the car display device 30 displays 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 that displays the distributed content.

[0035] 2, the hall display device 40 displays content distributed from the remote video distribution server 50 via the communication line 12. The hall display device 40 has a network interface 41 connectable to the communication line 12, and a display unit 42 that displays the distributed content.

[0036] 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 that can be connected to the communication line 12.

[0037] 3 , the remote video distribution server 50 includes a data traffic calculation unit 61, a distribution effect calculation unit 62, and a data traffic control unit 63, each of which will be described in detail 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 communication volume calculation unit> 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 for a predetermined period. Here, the data communication volume is the total sum of the data communication volumes between all the display devices 11 in the remote video distribution system 10 and the remote video distribution server 50. The predetermined period is a delimited period for determining the usage fee in the usage fee pattern of the communication line 12, and is, for example, one month.

[0039] <4-2. Distribution Effect Calculation Unit> The distribution effect calculation unit 62 calculates the distribution effect of 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 a passenger in the car room 21 or the hall 22.

[0040] The delivery effect calculation unit 62 determines the delivery effect as the proportion of the time during which a passenger is present in the car 21 to the time during which content is displayed by the car display device 30. If this proportion is high, the delivery effect is high, and if this proportion is low, the delivery effect is low. The time during which a passenger is present in the car 21 is calculated based on the time when the above-mentioned human presence sensor 25 detects the presence of a passenger in the car 21.

[0041] Furthermore, the delivery effect calculation unit 62 determines the delivery effect as the proportion of the time during which a user is present at the hall 22 to the time during which content is displayed by the hall display device 40. If this proportion is high, the delivery effect is high, and if this proportion is low, the delivery effect is low. The time during which a user is present at the hall 22 is calculated based on the time during which the presence of a user at the hall 22 is detected by the human presence sensor 26 described above.

[0042] 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 using the car room 21 or the hall 22 .

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

[0044] Furthermore, the distribution effect calculation unit 62 may determine the number of passengers waiting at the hall 22 for dispatch during the time that content is being distributed by the hall display device 40 as the distribution effect. Specifically, the product of the time that content is being distributed and the number of passengers may be calculated as the distribution effect. The larger this product is, the higher the distribution effect is, and the smaller this product is, the lower the distribution effect is. The number of passengers at the hall 22 may be calculated by photographing passengers at the hall 22 with a camera installed at the hall 22 and analyzing the photographed image.

[0045] The number of passengers using elevator 20 is not limited to calculation by analyzing images taken by a camera installed in car room 21 or hall 22, but may also be calculated by the registration history of a destination forecast system or a car scale device. A destination forecast system is a system that allows passengers to register their destination floors before boarding, and guides passengers with the same destination floor to the same elevator 20, making operation more efficient.

[0046] As another example of the embodiment, the delivery effect calculation unit 62 may calculate the delivery effect of the content by indirectly checking whether the user has viewed the content.

[0047] For example, in a system in which an elevator 20 is linked to a customer's smartphone, if the content displayed by the display device 11 is linked to the content on the smartphone, the display device 11 on which the customer clicks on the smartphone content a small number of times may be calculated to have a low distribution effect, and the display device 11 on which the customer clicks on the smartphone content a large number of times may be calculated to have a high distribution effect.

[0048] Furthermore, the delivery effect calculation unit 62 may calculate the delivery effect of the content based on the number of times that a QR code (registered trademark) displayed on the display device 11 is read by passengers of the car room 21 or the hall 22. For example, the delivery effect may be calculated to be low for a display device 11 whose QR code has been read a small number of times, and the delivery effect may be calculated to be high for a display device 11 whose QR code has been read a large number of times.

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

[0050] As another example of an embodiment, the distribution effect calculation unit 62 may calculate the distribution effect of content based on the number of times or the display time of the content. Here, in addition to displaying normal content, the display device 11 may display interruption content related to the operation of the elevator 20. Examples of interruption content include warning content regarding the usage status of the elevator 20 and educational content on how to use the elevator depending on the attributes of users.

[0051] For example, the delivery effect may be calculated to be low for the display device 11 of the elevator 20 that has a lot of interruption content and a small number of times or a small amount of time for displaying normal content. Also, the delivery effect may be calculated to be high for the display device 11 of the elevator 20 that has a small amount of interruption content and a large number of times or a large amount of time for displaying normal content.

[0052] As another example of an embodiment, the delivery effect calculation unit 62 may calculate the delivery effect of content based on the amount of time that a user of the car 21 or the hall 22 is looking at the display device 11. For example, the delivery effect may be calculated to be low for the display device 11 of an elevator 20 for which the user is looking at the display device 11 for a short period of time, and the delivery effect may be calculated to be high for the display device 11 of an elevator 20 for which the user is looking at the display device 11 for a long period of time. The amount of time that the user is looking at the display device 11 may be calculated by analyzing an image captured by a camera installed in the car 21 or the hall 22 and detecting the user's line of sight.

[0053] <4-3. Data communication volume control unit> When the data communication volume becomes equal to or greater than the first data communication volume during a predetermined period, the data communication volume control unit 63 reduces the data communication volume to a display device 11 for which the distribution effect calculated by the distribution effect calculation unit 62 is low. Here, the first data communication volume is set to be lower than the basic data communication volume described above. Preferred means for reducing the data communication volume include reducing the number or types of content to be distributed, reducing the data size of the content to be distributed, stopping the distribution of content with low priority, reducing the frequency of content distribution, changing the encoding specifications or conditions of the content to be distributed, etc.

[0054] As a result, when the data communication volume exceeds the first data communication volume and there is no room left until the basic data communication volume, the communication cost can be reduced by calculating the content distribution effect of each display device 11 and reducing the data communication volume to display devices 11 with low distribution effect. Furthermore, since the data communication volume to display devices 11 with low content distribution effect is reduced, the quality of the content distribution service to users of the elevator 20 is not impaired.

[0055] On the other hand, when the data communication volume is less than the second data communication volume during a predetermined period, the data communication volume control unit 63 increases the data communication volume to the display device 11 having a high distribution effect calculated by the distribution effect calculation unit 62. Means for increasing the data communication volume are preferably to increase the number or types of content to be distributed, increase the data size of the content to be distributed, increase the content distribution frequency, change the encoding specifications or conditions of the content to be distributed, etc. The second data communication volume is less than the first data communication volume.

[0056] As a result, when the data communication volume is less than the second data communication volume and there is room up to the basic data communication volume, the quality of the content distribution service to passengers of the elevator 20 can be improved by calculating the content distribution effect of each display device 11 and increasing the data communication volume to the display device 11 with the highest distribution effect.

[0057] The data communication volume control unit 63 of this embodiment is configured to reduce the data communication volume to display devices 11 with a low delivery effect calculated by the delivery effect calculation unit 62 when the data communication volume becomes equal to or greater than a second data communication volume during a predetermined period, and to increase the data communication volume to display devices 11 with a high delivery effect calculated by the delivery effect calculation unit 62 when the data communication volume is less than a predetermined data communication volume. However, the data communication volume control unit 63 may be configured to only reduce the data communication volume to display devices 11 with a low delivery effect, or may be configured to increase the data communication volume to display devices 11 with a high delivery effect.

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

[0059] As another example of the embodiment, when a disaster occurs, the data communication volume control unit 63 may increase the data communication volume to the display device 11 of the building 13 in the disaster-stricken area and decrease the data communication volume to the display device 11 of the building 13 in other areas. This makes it possible to ensure the data communication volume in the disaster-stricken area in the event of a disaster.

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

[0061] 4, in step S11, the data communication amount calculation unit 61 of the remote video distribution server 50 starts adding up the data communication amount of the entire remote video distribution system 10. In step S12, it is confirmed whether the data communication amount of the entire remote video distribution system 10 is equal to or greater than a first data communication amount, and if it is equal to or greater than the first data communication amount, there is not enough data communication amount up to the basic data communication amount, so the process proceeds to step S13, and if it is less than the first data communication amount, 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 in 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 a low distribution effect, and proceeds to step S18.

[0063] In step S15, it is confirmed whether the data communication volume of the entire remote video distribution system 10 is less than the second data communication volume. If it is less than the second data communication volume, there is still room for the basic data communication volume, so the process proceeds to step S16. If it is equal to or greater than the second predetermined data communication volume, the process proceeds to step S18 (in particular, the normal mode is established without decreasing or increasing the data communication volume). In step S16, the distribution effect calculation unit 62 of the remote video distribution server 50 calculates the distribution effect of content for each display device 11 of the remote video distribution system 10. In step S17, the data communication volume control unit 63 of the remote video distribution server 50 increases the data communication volume for the display device 11 with the high distribution effect, and the process proceeds to step S18.

[0064] In step S18, the data communication amount 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 communication amount calculation unit 61 of the remote video distribution server 50 resets the data communication amount.

[0065] 6. Effects The remote video distribution system 10 can maintain the quality of the content distribution service to elevator users 20 while reducing communication costs. More specifically, when the data communication volume is equal to or greater than a first data communication volume, which is set lower than a basic data communication volume for which a flat fee is charged, the data communication volume to display devices 11 with low content distribution effectiveness is reduced so as not to exceed the basic data communication volume as much as possible. This reduces communication costs. Furthermore, because the data communication volume to display devices 11 with low content distribution effectiveness is reduced, the quality of the content distribution service to elevator users 20 is not compromised.

[0066] Furthermore, when the data communication volume is less than the second data communication volume, there is still room before it exceeds the basic data communication volume, so the quality of the content distribution service can be improved by increasing the data communication volume to display devices 11 that have a high content distribution effect.

[0067] It should be noted that the present invention is not limited to the above-described embodiment and its modifications, and various changes and modifications are possible within the scope of the claims of this application.
