Description

Technology Field

[0001] The present invention relates to an advertising system, and more specifically, to an intelligent store advertising management device for real-time operational control and Bluetooth-POS-linked visitor analysis in an advertising system. Background Technology

[0002] Generally, digital signage refers to a digital out-of-home (DOOH) advertising medium that delivers digital content, such as videos and images, through display terminals. Replacing traditional analog print, it allows for real-time content replacement and attracts high visual attention, making it widely used in retail stores, transportation facilities, and public spaces. In particular, within the franchise and franchise business sectors, it serves as a key tool for headquarters to centrally manage the promotion and operational status of each branch.

[0003] However, the advertising display devices installed in stores in conventional advertising systems have the following problems.

[0004] First, there are issues regarding visual clutter and cable management around the checkout counter. The point-of-sale (POS) area, which is the core of store operations, is connected to numerous peripheral devices for payment, leading to a chronic problem where power cords and data communication cables on the back of the devices are intricately tangled and exposed. These "messy cables" and the "clunky appearance" of the devices damage the store's brand image and undermine a clean impression. Conventional technology has focused solely on the function of displaying advertisements and has failed to provide a functional solution to organize the store environment by visually exposing these messy wiring and hardware elements.

[0005] Second, regarding the environmental aspects of retail applications, there are issues related to visual visibility and illumination optimization. Retail stores constantly operate high-intensity indoor lighting to highlight products. Conventional advertising display devices have limitations; under such strong external lighting, diffuse reflection occurs or contrast is reduced, causing a sharp decline in advertising effectiveness. Furthermore, given the nature of the store environment where customers' gazes move from various angles, optical design capable of delivering distortion-free information from the sides as well as the front is essential, along with hardware optimization technology that actively controls LED brightness according to ambient light levels.

[0006] Third, there is an issue regarding the ease of installation and maintenance. For advertising display devices operating in the aforementioned specialized environments, convenience in installation and management is also critical. Existing signage devices suffer from poor maintenance convenience, as installation involves separate bracket construction and complex wiring, and the entire unit must be removed in the event of a malfunction. Given the nature of retail sites where specialized personnel are not always present, a modular hardware structure is required that allows even non-expert store employees to manage the system easily. In particular, the absence of mechanical mechanisms that allow for the rapid opening and closing of the housing or the partial replacement of LED panel modules during frequent advertising content changes or internal equipment inspections acts as a factor hindering operational efficiency.

[0007] Fourth, there is a problem regarding the limited delivery of advertisements. The video content displayed on the screen is limited only to products related to the store, resulting in poor advertising effectiveness for customers. It fails to provide opportunities to stimulate consumer sentiment through diverse video content in convenience stores, which are used by a diverse and large number of consumers.

[0008] In other words, conventional advertising display devices suffer from several problems: poor aesthetics due to the absence of a shielding structure that conceals exposed wiring and bulky POS equipment while minimizing space occupation; insufficient hardware optimization to ensure visibility in high-light store environments; low ease of maintenance; a lack of convenience in installation and management during maintenance; and the inability to provide opportunities to stimulate consumer sentiment due to the limited transmission of advertisements.

[0009] In addition, conventional digital signage-based advertising management systems have the following problems.

[0010] First, there is a lack of integration between advertising and actual payment data. While integration with Point of Sales (POS) data is essential to determine whether ad content exposure led to actual sales, existing devices focused on independent ad playback functions and lacked the capability to quantitatively analyze the correlation between ad viewing and purchasing behavior.

[0011] Second, there is a lack of effectiveness in store operation management. Despite frequent instances where business hours announced by headquarters are not strictly observed at the branch level, the existing system lacked hardware control mechanisms to detect or enforce compliance in real time. This contributes to a decline in brand image and the loss of potential customers.

[0012] Third, there is the issue of the reliability of visitor analysis data. Existing camera-based analysis methods have limitations in securing precise data due to lighting conditions or privacy concerns; furthermore, even when utilizing Bluetooth or Wi-Fi, it has been difficult to clearly distinguish between foot traffic simply passing by the store and customers actually staying inside, making it challenging to measure the effectiveness of advertising exposure. Prior art literature

[0013] Registered Patent Publication No. 10-1606491 (March 21, 2016) The problem to be solved

[0014] The present invention aims to solve the problems of the aforementioned conventional advertising display devices. Its purpose is to enhance the store's brand image and create a clean payment environment by physically concealing the bulky appearance and complexly exposed power and data cables around the POS terminal (improving the aesthetics and concealing the checkout environment); to ensure that advertising content is delivered without distortion even under strong indoor lighting conditions within the store by optimizing hardware illumination and securing a high-contrast viewing angle (securing optical visibility in high-illumination environments); to provide a mechanical mechanism that allows store employees to quickly open and close the housing, replace LED modules, or inspect internal devices without tools, even in environments without specialized personnel (maximizing maintenance convenience for non-experts); and to provide a retail-specific advertising platform that moves beyond monotonous advertisements limited to in-store products and effectively transmits diverse video content based on a hardware platform to stimulate the purchasing desires of a large consumer base in real time (securing diversity of advertising content and stimulating consumer psychology).

[0015] Furthermore, the present invention was created to solve the problems of the aforementioned conventional advertising system, and its purpose is to provide an intelligent store advertising management device capable of measuring the actual conversion efficiency of advertisements by combining precise visitor analysis based on Bluetooth signals with POS data, while simultaneously monitoring and forcibly controlling the operational status of a store in real time to induce mandatory compliance with business hours and maximize data-based marketing efficiency by linking digital signage with a store operation system and a visitor analysis algorithm. means of solving the problem

[0016] To achieve the aforementioned objectives, an intelligent store advertising management device for real-time operation control and Bluetooth-POS linked visitor analysis according to one aspect of the present invention is an intelligent store advertising management device included in a store server or a store display of an advertising management system comprising a main server, a store server, and a store display, and may include: a power management unit for automatically controlling the power of the store display according to a set operation schedule; an operation integrity maintenance unit for blocking arbitrary termination during an advertisement by periodically checking a heartbeat signal for the advertisement playback process of the store display; a first personnel counting unit for counting the number of mobile phones near the store display through Bluetooth signal scanning; and a second personnel counting unit for counting the actual number of visitors and purchases based on payment data linked with a POS terminal in the store; wherein the power management unit may cut off the power of the store display outside of the operating hours of the store based on the set operation schedule, and the operation integrity maintenance unit may include a watchdog process that immediately restarts (keep-alive) the advertisement playback process of the store display when the arbitrary termination signal is detected during the operating hours of the store.

[0017] According to another aspect of the present invention, the main server can calculate the purchase conversion rate of a specific advertising content by chronologically matching potential customer data collected from the first personnel counting unit with actual purchase data collected from the second personnel counting unit.

[0018] According to another aspect of the present invention, when a shortage of stock of a specific product is detected through the POS terminal or when payment data surges, the main server can control the frequency of sending advertisements related to the product to be changed in real time.

[0019] The power management unit can physically control the power on / off using the HDMI-CEC (Consumer Electronics Control) function of the store display, and the operational integrity maintenance unit can notify the main server when it detects an abnormal state of the store display to send a mobile push notification to the corresponding store manager terminal.

[0020] The first person counting unit can analyze the strength of the received Bluetooth signal (RSSI) to select and count only valid viewers within a set distance from the store display, and the main server can calculate an exposure performance index for each advertisement by matching the advertisement playback log received from the operational integrity maintenance unit with the time-based person count data received from the pedestrian traffic measurement unit.

[0021] To achieve the aforementioned purpose, an advertising display device (or store display) according to another aspect of the present invention may have the following features.

[0022] 1) It is configured as a standalone screen housing for shielding the area behind the checkout counter, thereby improving the aesthetics of the checkout environment and achieving the purpose of concealment. The main body of the device can be designed as a screen-shaped standalone housing that extensively covers the front of the area where POS terminals and auxiliary devices are located. As a separate structure that is not electrically connected to the payment system, it can serve as a 'visual barrier' that physically conceals the messy cables and bulky equipment located behind it when the device is installed. By being composed of a spatially separated support frame, the device itself stands firmly on its own, thereby blocking the cluttered environment behind it from the customer's view and creating an organized store image.

[0023] 2) Optical visibility in high-illumination environments can be secured by implementing a manager-configurable brightness optimization system. Instead of an automatic detection system, the device is equipped with physical control buttons or a manual operation board that allow store managers to directly set LED brightness according to the lighting environment. This enables the maintenance of optimal contrast so that content is displayed without distortion, even in brightly lit retail stores. By applying an anti-reflection hard coating film to the surface of the LED panel, the degradation of visibility caused by reflection from indoor lighting can be prevented hardware-wise.

[0024] 3) By equipping a standalone content playback hardware platform, it is possible to ensure diversity in advertising content and stimulate consumer sentiment. An embedded playback board that operates independently without relying on POS system resources is installed inside the device, allowing for the independent transmission of not only store promotional videos but also high-definition advertisements from external partners and various information. By including a high-performance hardware decoder that supports various video sources, it can perform the function of a retail advertising medium by displaying dynamic and clear video content in real-time that can stimulate a large consumer base. Effects of the invention

[0025] As explained above, according to the advertising display device (or store display) of the present invention, there are: 1) an improvement in the aesthetics of the checkout counter environment and a shielding effect, 2) an effect of securing optical visibility in high-illumination environments, and 3) an effect of securing diversity of advertising content and stimulating consumer psychology.

[0026] In addition, as explained above, the advertising system of the present invention has the following effects: 1) It improves the completeness of advertising performance measurement. That is, by providing advertisers with complete data—such as "how many people viewed it (Bluetooth) and how many of them made a purchase (POS)"—rather than simply stating that "an advertisement was played," it enhances media value, thereby ensuring compliance with the Fair Trade Commission's advertising standard guidelines and transparency in advertising execution. 2) It improves operational efficiency and security. That is, it prevents arbitrary manipulation by store owners while simultaneously reducing management costs through automated power management. 3) It can provide additional business intelligence (BI), such as analyzing store congestion or optimizing staffing, through purchase rate data relative to foot traffic. 4) By utilizing physical power control with HDMI-CEC functionality rather than a simple software power-saving mode, it can fundamentally block standby power generated after closing and unnecessary power consumption by display panels, thereby maximizing energy efficiency and reducing carbon emissions. (This provides energy management efficiency that meets the strengthened corporate ESG management standards for 2026.) In addition, by automating the hassle of store managers having to manually turn displays on and off or check playback status, it increases the work engagement of field personnel and eliminates the risk of missed ads due to negligence, thereby optimizing store operation management and reducing costs. 5) Through the Watchdog process and Keep-alive function, immediate self-healing is enabled even in the event of system errors, memory shortages, or unauthorized shutdowns, thereby maximizing ad uptime. This prevents disputes with advertisers caused by ad interruptions and guarantees service reliability.6) In the event of a hardware failure that cannot be recovered via software, a proactive maintenance system can be established to minimize the time to detect the failure through real-time push notifications connecting the store server, main server, and administrator terminal. This enables an intelligent preventive maintenance system that moves away from reactive handling. 7) Moving beyond the method of simply counting all terminals within the signal range, only individuals within the effective line of sight of the display are selected through RSSI (Signal Signal Strength) analysis. This allows for the acquisition of actual 'Effective Impression' data, excluding pedestrians beyond walls or casual passersby. 8) By matching ad playback logs with real-time pedestrian traffic data on a one-to-one basis to calculate an impression performance index for each ad, objective performance reports can be provided to advertisers. 9) Since it utilizes only existing HDMI standard protocols and Bluetooth modules without the need for separate complex sensors or physical switch installations, it has high versatility that allows for the construction of an intelligent system at low cost even in aging store environments. Additionally, unlike camera-based facial recognition methods, it adopts a Bluetooth signal scanning method, which is free from controversies regarding privacy infringement while safely collecting large-scale pedestrian traffic statistics data.

Specific details for implementing the invention

[0028] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. In assigning reference numerals to the components of each drawing, identical components are given the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, when describing embodiments of the present invention, if it is determined that a detailed description of related known components or functions could obscure the essence of the present invention, such detailed description is omitted.

[0029] FIG. 1 is a configuration diagram of an intelligent store advertising management system for mandatory compliance with operating hours and Bluetooth-based pedestrian traffic analysis according to an embodiment of the present invention. As shown in FIG. 1, it may include a store display (1), a store server (3), a main server (5), a communication network (7), and a POS terminal (9).

[0030] The store display (1) represents an advertising display terminal device installed in each store to display advertisements through a screen, and can perform real-time advertisement output (rendering) and player software survival monitoring.

[0031] The store server (3) can perform local content storage, monitoring and recovery of the display status within the store, etc.

[0032] The main server (5) can perform advertising scheduling, content distribution, and collection of the overall system status.

[0033] The communication network (7) represents a single or combined communication network for enabling communication between the store display (1), store server (3), main server (5), and POS terminal (9) via wired, wireless and / or the internet.

[0034] The POS terminal (9) is a point-of-sale information management system installed in each store, representing software and hardware devices that process product sales, payment, inventory management, and sales analysis in real time at offline stores.

[0035] The store display (1) may include a POS-linked display device in which a POS terminal (9) is coupled to the outlet of the store display (1) as shown in (a) and (b) of FIG. 8.

[0036] The store display (1) is placed at the front of the checkout counter to conceal the cluttered and unorganized appearance of the checkout counter and the bulky design of the POS machine, while simultaneously displaying video through the front display panel to maximize the promotional effect of the store. By allowing the store to possess its own advertising display panel, it can establish the store's unique identity and enable LED panels to become a popular item rather than being the exclusive property of large corporations (allowing the store to become Instagram-friendly).

[0037] The store display (1) is an interior-friendly product that does not feel out of place even when placed anywhere in the store other than the checkout counter, and can be customized in color to match the store atmosphere. It provides a more vivid and lively image compared to an LCD, which increases the concentration of the image even from a distance, making it excellent for store promotion and advertising effects. It also maintains vivid colors without color distortion even when viewing the display from the side, making it excellent for advertising effects. Furthermore, it has a long lifespan of over 100,000 hours on average with an LED panel, which reduces concerns and burdens regarding maintenance. It can also have high energy efficiency so that there is no burden on electricity costs even when operating 24 hours a day for a year (e.g., less than 23,000 won when used 24 hours a day for a year).

[0038] The expandable store display (1) is an all-in-one type that includes a mini PC, router, and power strip in addition to the basic product configuration, and has all the necessary components for system operation built in. Basically, these product lines (mini PC, router, power strip) are generally exposed to the outside, but the expandable product has all the necessary components for the system built into the product, thereby enabling the system to transmit and receive components and external components independently, and at the same time, can improve the aesthetics and reduce clutter with a single product.

[0039] The store server (3) is installed for each store and can control the store display (1), and the main server (5) is connected to the store server (3) through a communication network (7) to schedule operating times and provide advertising content accordingly.

[0040] The system of Fig. 1 may have feature 1 of automatic power management based on an operating time schedule (Auto-Power Scheduling), feature 2 of real-time status monitoring using a heartbeat mechanism (Live Status Tracking), feature 3 of anti-termination logic design to prevent arbitrary termination within operating time (Anti-Termination Logic), and feature 4 of proving the actual performance of advertising by combining the feature of Bluetooth-based pedestrian traffic measurement and the feature of purchase conversion analysis based on POS payment data.

[0041] According to Feature 1, for example, the main server (5) synchronizes the operating hours data for each store, and the store server (3) can control the display device (1) by issuing commands to the OS level or hardware controller (such as CEC control) based on the data to automatically switch to a physical power cut-off or low-power mode outside of the set time. This can be done not only by simply terminating the software, but also by using hardware control signals for energy saving and panel life extension.

[0042] According to feature 2, for example, a status packet (Heartbeat) is exchanged between the store display (1) and the store server (3) at regular intervals (e.g., 5 seconds), and if the packet is interrupted or the screen rendering process does not respond, an alarm can be sent immediately to the main server (5). In addition to checking whether the screen is turned on, it is possible to cross-verify in real time whether the actual advertisement video is playing normally (whether the content playback process is alive).

[0043] According to feature 3, for example, during the set advertising screening time, control of input devices (keyboard, mouse, remote control) for the operation of the store display device (1) may be restricted, or a watchdog process that is immediately restarted (Keep-alive) upon forced termination through the task manager may be executed. This can technically guarantee the fulfillment of the contract with the advertiser (securing advertising exposure time) by completely blocking the act of the store owner or outsiders arbitrarily stopping the advertisement.

[0044] According to feature 4, POS-linked conversion tracking can be performed. The store server (3) collects data on the time of payment and the number of payments from the POS terminal (9) in real-time or in batch mode, analyzes the sales change of a specific product through the POS (advertisement-payment correlation) immediately after a specific advertisement is broadcast or during the broadcast time, and, for example, calculates the ratio of the 'actual payment number' aggregated by the POS to the 'store entry / stay number' measured by Bluetooth, i.e., the purchase rate relative to visitors (Capture Rate), thereby quantifying the effect of the advertisement on store inflow.

[0045] FIG. 2 is a configuration diagram of an intelligent store advertising management device (2) for real-time operation control and Bluetooth-POS linked visitor analysis according to an embodiment of the present invention.

[0046] According to the present embodiment as illustrated in the drawing, an intelligent store advertising management device (2) is installed in the store server (3) or store display (1) to perform functions such as power management, integrity maintenance, measurement of foot traffic, and analysis of actual purchases and conversion rates linked to POS terminals. To this end, the intelligent store advertising management device (2) may include a power management unit (21), an operational integrity maintenance unit (23), a first person counting unit (25), and a second person counting unit (27).

[0047] The power management unit (21) is designed to cut off the power to the store display (1) outside of store operating hours and operate it during operating hours based on an operating schedule. For example, by controlling the power to the store display (1) hardware physically on / off as well as shutting down at the operating system level through the HDMI-CEC (Consumer Electronics Control) function, which is an interface standard with the store display (1), unnecessary power waste can be prevented at the source.

[0048] The operational integrity maintenance unit (23) is designed to periodically monitor the heartbeat signal for the advertisement playback process of the store display (1) to block arbitrary termination during the advertisement and to perform a process of immediately restarting (Keep-alive) when termination is detected. If the abnormal state of the store display (1) persists despite software-based restart attempts, it immediately notifies the main server (5), and the main server (5) can form a three-dimensional management network that induces on-site action by sending a mobile push notification to the store manager's terminal based on the received fault information.

[0049] The operational integrity maintenance unit (23) can periodically monitor the heartbeat of the ad playback process through the screen rendering process, and if the monitoring result determines that the process is terminated, it can immediately keep-alive through the watchdog process.

[0050] In this embodiment, the screen rendering process may include a process in which a computer program interprets data in code (HTML, 3D models, etc.) and converts it into a graphic image or video that a user can see, and outputs it to the screen. The watchdog process may include a safety device that monitors whether the system is operating normally and automatically restores (restarts) the system when an error occurs and it falls into a state of no response (freezing).

[0051] The watchdog process acts as a timer with a set time (timeout), and performs a monitoring timer function that periodically resets (Kick / Petting) the timer when the system is normal. Additionally, if the system stops due to a software error or hardware defect and fails to reset the timer, it can perform an automatic recovery function that forcibly reboots the system or performs a recovery operation as soon as the time expires.

[0052] The first person counting unit (25) is for collecting population data by counting the number of mobile phones near the store display (1) through Bluetooth signal scanning, and can select and count only valid viewers existing within a set distance from the store display (1) by analyzing the strength (RSSI) of the received Bluetooth signal.

[0053] For example, the floating population measuring unit (25) can ensure data accuracy by analyzing the received signal strength indicator (RSSI) value in real time and not simply counting all people who receive the signal, but by selectively counting only terminals that are within a set effective distance (e.g., 2 to 5 m) from the display as valid viewers.

[0054] The second personnel counting unit (27) is linked with the POS terminal (9) in the store to count the actual number of visitors and purchases based on payment data. Since POS data is sensitive information, only non-identified statistical values ​​(such as the number of payments by time period) among the payment information can be used in accordance with the guidelines of the Personal Information Protection Commission.

[0055] The main server (5) can automatically calculate the exposure performance index for each advertisement content by matching the actual advertisement playback log transmitted from the operational integrity maintenance unit (23) with the number of people per time period transmitted from the population measurement unit (25), and by calculating how many valid people were present at the time a specific advertisement was broadcast.

[0056] The main server (5) can calculate the purchase conversion rate of a specific advertising content by matching potential customer data collected from the first personnel counting unit (25) and actual purchase data collected from the second personnel counting unit (27) in a time-series manner.

[0057] The intelligent store advertising management device (2) or main server (5) can control the frequency of sending advertisements related to a product in real time when a shortage of stock of a specific product is detected or payment data increases rapidly through the POS terminal (9).

[0058] FIGS. 3 to 7 are flowcharts of an intelligent store advertising management method for real-time operation control and Bluetooth-POS linked visitor analysis according to an embodiment of the present invention, and since they are applied to the device of FIG. 1-2, they are explained in parallel with the operation of said device.

[0059] FIG. 3 is a flowchart showing an example of the control process of an HDMI-CEC-based store display (1) by a power management unit (21). As shown in the figure, the power management unit (21) performs a schedule matching process to check whether the current time is within the operating time by checking the operating schedule (e.g., 09:00~22:00) stored in internal memory (S301), performs an HDMI-CEC command transmission process to physically transmit a Power On command to the display along with a 'System Audio Mode Request' or 'Routing Change' signal via the HDMI-CEC (Consumer Electronics Control) protocol when the operating time is entered (S303), and performs a forced cut-off process to cut off power without administrator intervention by transmitting a Power Off signal via the same path when the operating time ends (S305).

[0060] FIG. 4 is a flowchart showing an example of a watchdog and notification process of an operational integrity maintenance unit (23). As shown in the figure, the operational integrity maintenance unit (23) performs heartbeat monitoring by receiving periodic signals from an ad playback process while a watchdog process is stationed to ensure the continuity of ad playback (S401). If the signal is disconnected or the process is terminated arbitrarily, the watchdog immediately detects this and restarts the process (Keep-alive) (S403). If the self-restart attempt fails or a hardware error is detected, an error log is transmitted from the store server (3) to the main server (5) via the communication network (7), and the main server (5) immediately sends a mobile push notification to the administrator terminal (S405).

[0061] FIG. 5 is an example diagram of the RSSI-based valid viewer selection principle of the first person counting unit (25). As shown in the figure, the pedestrian traffic measuring unit (25) detects surrounding smart devices through Bluetooth scanning, scans the Bluetooth signal of a surrounding device (e.g., a mobile phone) to collect the signal (S501), performs an RSSI analysis process to convert the received signal strength (RSSI) into a distance value (S503), excludes data with a signal weaker (far distance) than a set threshold (e.g., -60dBm or less, within about 3m), and performs a valid filtering process to increase the precision of the data by counting only valid viewers who remain within the line of sight of the store display (1) (S505).

[0062] FIG. 6 is a flowchart of the POS-linked purchase conversion data collection flowchart of the second personnel counting unit (27). As shown in the figure, when a payment occurs, POS data including payment time / item / amount data is collected in real time from the POS terminal (9) (S601), and after primary processing of the data regarding de-identification processing and sales change trends of advertised products (S603), the processed POS data is transmitted to the store server (3) or main server (5) (S605).

[0063] FIG. 7 is a flowchart of an algorithm for calculating an exposure performance index per advertisement of a main server (5). As shown in the figure, the main server (5) analyzes big data collected from the store server (3). For example, it performs a log matching process that synchronizes the time period when a specific advertisement content 'A' is played with the valid viewer data and processed POS data for that time period (S701), and calculates an exposure performance index per advertisement by integrating and analyzing all collected data (playback log + pedestrian traffic + POS sales), and issues a performance report including, for example, "ad exposure time compliance rate 100%, purchase conversion rate relative to exposure 2.5%" (S703).

[0064] According to the above-described embodiment, the following features are provided for maintaining integrity and correlation analysis regarding advertisements.

[0065] Double Watchdog System: A primary watchdog that prevents the process from ending on its own inside the store display (2) and a secondary watchdog that issues a forced reboot command when a heartbeat is not received from the store server (3) interact to ensure that advertisements are broadcast during operating hours.

[0066] Edge computing-based data processing: By performing primary filtering and anonymization processing on the store server (3) for the massive amount of raw data generated from Bluetooth (BT) and POS (9), and then transmitting only meaningful statistical values ​​to the main server (5), network load can be minimized and personal information protection can be enhanced.

[0067] Time series event matching algorithm : The main server (5) can statistically calculate the causal relationship between the advertisement and the purchase behavior by merging the three events in a time series: ‘advertisement A playback time - increase in Bluetooth recognition users - occurrence of sales of the advertisement product in the POS’.

[0068] According to the present invention, video content is transmitted, controlled, and managed through the main server (5) of the system of FIG. 1, and can receive content from the main server (5) through the server (3) installed in the store. The system can transmit and manage video content from any store nationwide where the system is installed through the main server (5).

[0069] Store information can be registered through the main server (5), and after registering the device number of the display (1) product installed in the store in the main server (5) store information, when video content is transmitted to the corresponding store, the video is transmitted through the store server (3) and panel (1) of the device installed in the store.

[0070] Through the main server (5), video content can be scheduled and managed by day and time (e.g., Monday, Tuesday, Wednesday, Thursday, Friday, 01:00 to 24:00), and the video can be automatically turned off except at the start and end times of the video broadcast, thereby fulfilling the essential requirements for an advertising contract.

[0071] The system of Fig. 1 can transmit video by region, zone, and store. When transmitting video by designating a headquarters, it is possible to set it so that the video is automatically transmitted to all franchise stores registered under the headquarters. It is also possible to check in real-time which video is currently being transmitted to the store by checking the log information of the advertisement being transmitted from the main server (5), and to download it in the form of an Excel file.

[0072] It is very important to be able to check the current on / off status of the store's equipment in real time through the store status on the main server (5), as this operates based on the schedule according to the advertising transmission contract between the client company and our company.

[0073] The display (1) or server (3) installed in the store is designed so that the store owner or outsiders cannot arbitrarily shut it down, and even if the program is forcibly shut down, the program is played again, which is a very important feature since the video is broadcast on a schedule basis under an advertising broadcast contract with the client company.

[0074] The server (3) or display (1) of the store has a built-in Bluetooth-based people counting function, so that the number of people watching the advertisement video in the store can be checked in hours and minutes through the main server (5) and can be downloaded in the form of an Excel file. This is a function that counts people based on collecting the unique Bluetooth address information of the mobile phones of customers visiting the store, and can aggregate the number of people watching the advertisement video and provide it to the advertising company (e.g., can be viewed and downloaded in hours and minutes via an Excel file).

[0075] According to the embodiments of the present invention described above, beyond the question of "Did the advertisement come out well without turning off?", it is possible to maximize advertiser trust by providing objective indicators regarding "how many potential customers were actually near the advertisement?", and flexible intelligent operation is possible based on people counting data, such as exposing specific advertisements more frequently during times with many people or switching the display to a power-saving mode during times with few people, and it is possible to expand into a reasonable business model (performance-based billing model) that determines advertising costs in proportion to the actual number of people in the surrounding area rather than the number of exposures.

[0076] According to the embodiment of the present invention described above, by using physical power control with HDMI-CEC function rather than a simple software power saving mode, standby power and unnecessary power consumption of the display panel after closing can be completely eliminated. Additionally, by automating the hassle of store managers having to manually turn the display power on and off or check the playback status, the work engagement of on-site personnel can be increased and the risk of missing advertisements due to negligence in management can be eliminated.

[0077] According to the embodiments of the present invention described above, immediate self-healing can be achieved through a watchdog process and a keep-alive function even in the event of a system error, memory shortage, or arbitrary termination by an unauthorized user, thereby maximizing the uptime.

[0078] According to the aforementioned embodiment of the present invention, in the event of a hardware failure that cannot be recovered by software, a preemptive maintenance system can be established to minimize the time to recognize the failure through real-time push notifications leading from the store server to the main server to the administrator terminal. Furthermore, by moving away from a method of simply counting all terminals within the signal range, only the people within the effective line of sight of the display can be selected through RSSI (signal strength) analysis, and an exposure performance index for each advertisement can be calculated by matching the advertisement playback log with real-time pedestrian traffic data on a 1:1 basis.

[0079] According to the aforementioned embodiment of the present invention, since only existing HDMI standard protocols and Bluetooth modules are utilized without the need for separate complex sensors or physical switch installations, it possesses high versatility that enables the construction of an intelligent system at low cost even in aging store environments. Furthermore, by adopting a Bluetooth signal scanning method unlike camera-based facial recognition methods, it is free from controversies regarding personal information infringement while safely collecting large-scale pedestrian traffic statistics data.

[0080] The foregoing description is merely an illustrative explanation of the technical concept of the present invention, and those skilled in the art to which the present invention pertains will be able to make various modifications and variations within the scope of the essential characteristics of the present invention. Accordingly, the embodiments disclosed in the present invention are intended to explain, not limit, the technical concept of the present invention, and the scope of the technical concept of the present invention is not limited by these embodiments.
