Here, the contents may include various news (regional issues, cultures, disasters, accidents, events, etc.), advertisements, personal contents produced by creators, and the like.

The content providing device 100 includes code division multiple access (CDMA) technology, wideband CDMA (WCDMA) technology, time division multiple access (TDMA) technology, frequency division multiple access (FDMA) technology, orthogonal frequency division multiplexing (OFDM) technology , Filtered OFDM technology, CP (cyclic prefix)-OFDM technology, DFT-s-OFDM (discrete Fourier transform-spread-OFDM) technology, OFDMA (orthogonal frequency division multiple access) technology, SC (single carrier)-FDMA technology, NOMA (Non-orthogonal Multiple Access) technology, GFDM (generalized frequency division multiplexing) technology, FBMC (filter bank multi-carrier) technology, UFMC (universal filtered multi-carrier) technology, SDMA (Space Division Multiple Access) technology, 5G (fifth) Generation) technology, or the like, may perform wireless communication with the display devices 210 to 240.

The content providing device 100 may collect contents to be displayed on the display devices 210 to 240 through various paths. For example, the content providing device 100 may collect contents from an external public content providing server 310, a personal terminal 320, and a newsletter 330 such as a newspaper or magazine published on a regional or national basis. have.

The public content providing server 310 is a national or regional broadcaster server such as KBS, MBC, etc., various newspaper company servers, a portal server such as Naver or Daum, a social network service (SNS) server including Instagram, Twitter, etc. It may include.

The personal terminal 320 may be an influencer with influence, a smartphone, a PC, etc. owned by the general public (military, college student, and community associations).

The content providing device 100 includes various news from the personal terminal 320 (here, news may mean information reported by a third party), issues, culture, disasters, incidents, accidents, Contents, etc. can be reported and collected. The content providing device 100 may collect real-time news and broadcast content provided by the public content providing server 310. In this case, the content providing device 100 may collect contents from the public content providing server 310 or the personal terminal 320 by a method such as web crawling. In addition, the content providing device 100 may collect contents by receiving various types of contents for the newsletter 330 from an administrator.

The content providing device 100 may display collected contents using various types of display devices.

For example, the content providing device 100 includes a display device 210 installed in a building, a display device 220 installed on a public road, a display device 230 installed on a mobile vehicle, and a mobile device 240 with a display. Contents can be displayed using, for example.

The display device 210 installed in the building may include an outdoor LED (Light Emitting Diode) billboard installed on the roof of the building, a monitor installed inside a building such as a hospital, and the like.

The display device 220 installed on a public road may include an outdoor LED billboard or the like installed on a roadside of a major road in which vehicles are frequently driven.

2 is a conceptual diagram illustrating a content sequence provided by the display devices according to FIG. 1.

Referring to FIG. 2, the content providing device 100 may determine a content sequence CSC to display content on the fixed display device FDP and the mobile display device MDP.

The content sequence CSC may indicate a temporal order of displaying contents on the display devices 210 to 240. For example, the content sequence (CSC) includes main content (n1 to n4) and advertisement content (c1 to c14) including news or entertainment produced on the airwaves, videos generated by individual creators, etc. at a predetermined time interval ( ti~tf) can indicate the temporal order displayed within. Here, the time interval (ti to tf) may be an interval between a start time (ti) for starting to display contents and an end time (tf) for ending display of contents. The content sequence CSC may instruct the advertisement contents c1 to c14 to be displayed between the main contents n1 to n4.

This content sequence CSC may be determined by being input to the content providing apparatus 100 in advance by an administrator. Meanwhile, when the same content sequence CSC is provided by both the fixed display device FDP and the mobile display device MDP, it is difficult to maximize the propagation power of the content because the same content is always displayed on the display devices at the same time. In addition, there is a problem in that it is difficult for a general user to continuously watch content displayed on the display devices 210 to 240.

In order to solve this problem, the content providing apparatus 100 according to an exemplary embodiment may separate and set a content sequence for a fixed display device FDP and a mobile display device MDP.

3 is a graph illustrating distances between fixed display devices according to FIG. 1.

Fixed display devices FDPs have a distance between positions where the fixed display devices FDPs are installed as an edge, and a two-dimensional or three-dimensional graph having each of the fixed display devices FDPs as nodes ( graph).

Referring to FIG. 3, a graph in which fixed display devices FDPs are displayed as nodes A to G, and the distances between locations where the fixed display devices FDPs are installed, as weights, are expressed as edges can be seen. .

For example, node A may have a distance of 3.4 from node C, a distance of 3.1 from node D, a distance of 2.5 from node B, and a distance of 3.2 from node E. Here, the distance expressed by the weight of the edges may mean a distance according to a shortest route between two fixed display devices, not a linear distance between two fixed display devices. Specifically, 3.4, which is the weight of the edge between the node A and the node C, may mean a distance according to the shortest path between the node A and the node C. Meanwhile, the shortest path from node A to node C and the shortest path from node C to node A may not coincide with each other. That is, depending on road conditions or conditions, if the departure point and the destination are reversed, the shortest route may be different. Accordingly, the weight of the edge may be an average value of the shortest path from node A to node C and the shortest path from node C to node A.

Here, the shortest paths represented by edges may be the shortest paths excluding a path passing through at least one other fixed display device among all the shortest paths formed between any two fixed display devices among the fixed display devices. have. For example, when the shortest path from node A to node G passes through node D, the shortest path from node A to node G is excluded from the shortest path and may not be expressed as an edge.

When the fixed display devices FDPs are represented by nodes A to G on a graph, the content providing device 100 may select one of the nodes A to G as the reference display device rf. For example, the reference display device rf may be a display device having the largest number of shortest paths (or the number of edges) to other fixed display devices among the fixed display devices.

That is, in FIG. 3, the number of shortest paths between node A and node D is the largest as four. In this case, one of the node A and the node D (eg, node A) may be determined as the reference display device rf. Specifically, if there are two or more nodes having the largest number of shortest paths, the reference display device may be determined in an order according to a unique identification symbol assigned to the fixed display device (FDP), an ip address, and the like.

Here, the reference display device rf may be a fixed display device that displays content according to a reference content sequence. The reference content sequence may be a content sequence set according to input to the content providing device 100 in advance by an administrator.

After the reference display device rf is selected, the content providing device 100, among the other fixed display devices excluding the reference display device rf, the i-th order corresponding to the display device in which the reference display device is located at the shortest distance ( i is a natural number of 1 or more) display devices may be selected.

For example, nodes B to D corresponding to the display device in which the reference display device is located at the shortest distance may be selected as the primary display devices among the remaining nodes except for the node A. Because node B corresponds to the shortest distance from node A, node D, and node E, which is the reference display device, among node A, node D, and node E having the shortest path, node B is the primary display device (i=1). Can be selected.

When the primary display devices (nodes A to D) are also selected, the content providing device 100 is a display device in which the primary display devices are located at the shortest distance among the other fixed display devices excluding the reference display device and the primary display devices. Secondary display devices corresponding to may be selected.

For example, the node E of FIG. 3 may be selected as the secondary display device (i=2) because the shortest path to the node B, which is the primary display device, corresponds to the shortest distance among the shortest paths.

In the same way, third to nth display devices (n is the number of fixed display devices) may be selected for the remaining fixed display devices that are not selected.

Meanwhile, in FIG. 3, the node F has the shortest path to the node G among the shortest paths, and the node G also has the shortest path to the node F among the shortest paths. Accordingly, nodes F and G corresponding to the remaining fixed display devices that have not been selected are not selected as 3rd to nth display devices.

In this case, the content providing device 100 may select a reference display device again for fixed display devices that have not been selected and remain, and may select a first to an nth display device. For example, the content providing device 100 selects a node F with a large number of shortest paths among the node F and the node G as the reference display device, and the node F selected as the reference display device corresponds to a display device located at the shortest distance. Node G to be used may be selected as the primary display device.

Meanwhile, node G is a primary display device for node F, which is a reference display device rf, and nodes B, C, and D may be distinguished from each other as a primary display device for node A, which is a reference display device rf. .

Specifically, in the i-th display device, a content sequence time-shifted by a predetermined time interval may be applied to a reference content sequence applied to the reference display device.

4 is an exemplary diagram illustrating a content sequence applied to the i-th display device according to FIG. 3.

Referring to FIG. 4, a reference content sequence rcsc applied to a node A, which is a reference display device rf, is shown. For example, the reference content sequence rcsc indicates that the main contents n1 to n4 are sequentially played, but advertisement contents c1 to c3 are played between the main contents n1 and n2, and the advertisement contents are played between the main contents n2 and n3. It may be indicated that contents c4 to c6 are played, and advertisement contents c7 to c14 are played between main contents n3 and n4.

The primary content sequence csc1 in which the reference content sequence rcsc is time-shifted by a predetermined time interval may be applied to the primary display device i=1 for the reference display device rf. That is, the primary content sequence csc1 is the reference content rcsc by a value ts1 obtained by converting the distance along the shortest paths between the primary display devices i=1 and the reference display device rf into time. ) Can be obtained by shifting the time.

For example, the value ts1 converted to time may be determined as in Equation 1 below.

In Equation 1, the front end is the distance according to the shortest path from the reference display device rf to the primary display device i=1 and the shortest distance from the primary display device i=1 to the reference display device rf. This formula is applied when the distances according to the paths are different, and the rear end is the distance according to the shortest path from the reference display device rf to the primary display device i=1, and in the primary display device i=1 It may be an equation applied when the distances along the shortest path to the reference display device rf are the same.

In Equation 1, p is the number of primary display devices (i=1), l _L is the distance from the reference display device rf to the primary display device (i=1) and the primary display device according to the shortest path It is a relatively large value among the distances along the shortest path from (i=1) to the reference display device rf, and ls is the shortest path from the reference display device rf to the primary display device (i=1). It is a relatively small value among the distance and the distance along the shortest path from the primary display device (i=1) to the reference display device rf, and v is the reference display device rf and the primary display device (i=1) It may be the average travel speed between. l denotes the distance according to the shortest path from the reference display device rf to the primary display device (i=1) and the distance according to the shortest path from the primary display device (i=1) to the reference display device rf When they are equal to each other, it may be a distance according to the shortest path between the reference display device rf and the primary display device i=1.

At this time, when the traffic amount from the reference display device rf to the primary display device (i=1) is greater than the traffic amount from the primary display device (i=1) to the reference display device rf, v is a positive sign And when the traffic amount from the reference display device rf to the primary display device is less than the traffic amount from the primary display device to the reference display device rf, v may be set to have a negative sign.

That is, when the traffic amount from the reference display device rf to the primary display device (i=1) is greater than the traffic amount from the primary display device (i=1) to the reference display device rf, you can watch fixed display devices. Also, it can be predicted that viewers will have a high tendency to move from the reference display device rf to the primary display device i=1. Accordingly, the primary content sequence csc1 may be generated by moving the reference content sequence rcsc in the direction of time. Accordingly, a viewer who has watched a specific content on the reference display device rf may continue to watch the content viewed on the reference display device rf on the primary display device (or view content that is temporally behind the viewed content). The likelihood of being able to do it can be increased.

On the other hand, when the traffic amount from the reference display device rf to the primary display device (i=1) is less than the traffic amount from the primary display device (i=1) to the reference display device rf, you can watch fixed display devices. Also, it can be predicted that viewers will have a high tendency to move from the primary display device (i=1) to the reference display device rf. In this case, the primary content sequence csc1 may be generated by moving the reference content sequence rcsc in the opposite direction of time.

In the same manner as the method of generating the primary content sequence csc1, the content providing device 100 includes shortest distances and traffic between the primary display device (i=1) and the secondary display device (i=2). Based on, the secondary content sequence csc2 may be generated by moving the primary content sequence csc1 in the flow direction of time or in the opposite flow direction of time. The secondary content sequence csc2 may be applied to a secondary display device (i=2).

The above-described process may be extended to a process of generating a k-th content sequence to be applied to the k-th display device. For example, the content providing device 100 includes the k-order display devices in the shortest distance among the remaining fixed display devices excluding the reference display device rf and the first-order k (k is a natural number of 2 or more)-order display devices. The k+ primary display devices corresponding to the located display devices may be selected.

5 is a conceptual diagram illustrating a content sequence applicable to mobile display devices that access the fixed display devices of FIG. 4.

In an embodiment, a content sequence in which the reference content sequence rcsc described above is basically shifted by a predetermined time interval may be applied to the mobile display devices. Meanwhile, there may be a case where the mobile display device MDP approaches the fixed display device FDP within a threshold distance.

In the content providing device 100 according to an exemplary embodiment, when the mobile display device MDP approaches the fixed display device FDP, the content displayed on the fixed display device FDP is displayed on the mobile display device MDP. It can support to be displayed by maintaining continuity.

For example, referring to FIG. 5, a case in which a specific mobile device mvn approaches a node A, which is a reference display device rf, within a certain threshold distance may be considered. Currently, node A, which is a reference display device rf, displays one of advertisement content c1 to c3, and a specific mobile device mvn transfers the reference content sequence rcsc in the opposite flow direction of the time tsm time. It is assumed that one of advertisement contents c7 to c14 is displayed by shifting by time by an interval.

At this time, the content providing device 100, based on the time tt it takes for the specific mobile device mvn to reach the reference display device rf, the specific mobile device mvn arrives at the reference display device rf A predetermined time (arrival) may be determined, and main contents to be played back on the reference display device rf may be determined at an expected arrival time (arrival).

Referring to FIG. 5, the content providing device 100 may determine that main contents n2, n3, and n4 are to be reproduced on the reference display device rf at an arrival scheduled time (arrival).

Next, the content providing device 100 includes the remaining main contents n2, excluding the main contents n3 already played on the specific mobile device mvn among the main contents n2, n3, and n4 to be played. By reconstructing n4) in chronological order, a content sequence to be applied to a specific mobile device mvn can be generated.

For example, in FIG. 5, the main content n3 is a content that has already been played back at the current time on a specific mobile device mvn, and thus the content providing device 100 includes the remaining main content ( A content sequence mcsc to be applied to a specific mobile device mvn may be generated by reconstructing the reference content sequence rcsc only with n2 and n4 and advertisement content before or after the main content. The content sequence mcsc generated here may be applied to a specific mobile device mvn when advertisement content is being played on a specific mobile device mvn. For example, when the advertisement content c7 is being played at the current point in time, it may be applied to a specific mobile device mvn within a time period c7 to c9 are sequentially played. Therefore, when the owner of the specific mobile device mvn arrives at the reference display device rf after the current point in time (current), the main content n2 that was displayed on the reference display device rf at the expected arrival time (arrival) You can watch from the beginning.
