Description

Method and system for providing cloud AI-based content through the construction of an integrated digital signage network.

[0001] The present invention relates to a method and system for providing content based on cloud AI through construction of a digital signage integration network, and more particularly, to a method and system for providing content based on cloud AI through construction of a digital signage integration network that connects a plurality of digital signages via the Internet and manages them in an integrated manner, and to a method and system for providing a method for increasing the effectiveness of integrated operation and information transmission for digital signages installed in various locations by generating new content based on specific content provided to each digital signage through AI in the cloud and transmitting it to the corresponding digital signage for display.

[0002] Digital signage, such as LED billboards, is an information delivery medium installed in various places such as public and commercial spaces to display content including information or advertisements.

[0003] Digital signage is installed not only outdoors but also in various places with high traffic and high visibility, such as subway stations, establishing itself as a medium for information delivery that can be accessed anytime and anywhere. Furthermore, digital signage continuously displays a variety of content, including information and advertisements, day or night, ensuring that people can view it.

[0004] In the past, digital signage was limited to displaying text and graphics in low-resolution, limited colors. However, recently, with the development and commercialization of LED digital signage, it has become possible to provide high-definition content with low power consumption.

[0005] Conventional digital signage has limitations in effectively conveying information because it repeatedly displays specific content to an unspecified number of people, making it boring due to the lack of change in information and content, and thus failing to attract people's attention or interest.

[0006] In addition, since conventional digital signage was installed independently and used individually, content had to be created individually according to the resolution of the digital signage, and in order to display content through the digital signage, the user (or administrator) had to visit the location where the digital signage was installed and play the content.

[0007] In other words, when content providers wanted to deliver information through multiple digital signage displays, they had to visit each digital signage location in person, which was inconvenient. For example, if there was a change in advertising schedule or an emergency disaster occurred, they had to visit each digital signage location, which was inconvenient.

[0008] In addition, because the content provider created and supplied a limited amount of content in advance, there was a problem in that it could not immediately reflect the environmental characteristics of the digital signage installation location, the personal characteristics of the content users, and the usage characteristics of the content.

[0009] Accordingly, the present invention proposes a method for efficiently utilizing and operating digital signage by constructing a digital signage integration network that integrates multiple digital signages installed in various locations and transmitting content for information transmission, including advertisements, from the cloud to each digital signage for display.

[0010] In addition, the present invention proposes a method of generating and providing new content for specific content in the cloud based on AI, based on environmental characteristics including weather, temperature, humidity, season or a combination thereof of a location where digital signage is located, human characteristics including trends, age groups, interests or a combination thereof of users of the content, or usage characteristics including public interest information, disaster information or advertising information to be provided through the content, or a combination thereof, thereby diversifying new content based on the content and displaying it through digital signage to attract people's attention, thereby increasing the effectiveness of information delivery and the usability of digital signage.

[0011] Next, we will briefly explain the prior art existing in the technical field of the present invention, and then describe the technical details that the present invention seeks to achieve differently from the prior art.

[0012] First, Korean Patent Publication No. 2018-0098073 (September 3, 2018) relates to a digital signage operating system and method, which transmits content and a schedule to be expressed as advertising information to digital signage, thereby enabling content to be displayed according to the schedule. Korean Patent Publication No. 2018-0098073 relates to a system in which digital signage recognizes customers and generates customer analysis information, and then displays advertising information according to the schedule or selects and displays advertising information based on the analysis information.

[0013] This Korean Patent Publication No. 2018-0098073 requires a separate device to recognize customers and generate analysis information on digital signage, and has the problem that it cannot be used in an environment where many people are watching.

[0014] On the other hand, the present invention utilizes AI to generate new content from the cloud for display on digital signage, thereby diversifying the content and attracting user interest, thereby enhancing the effectiveness of information delivery. Furthermore, it allows existing digital signage to be utilized as is. Therefore, the two inventions differ significantly in their technical structure, purpose, and effectiveness.

[0015] In addition, Korean Patent No. 1782087 (September 20, 2017) relates to a digital signage operating system and its operating method, which registers authentication information and advertising content to determine a digital signage on which to display an advertiser's advertising content, transmits the information to at least one digital signage, and displays the advertising content if the digital signage's own identification information and the received authentication information are identical.

[0016] The above Korean Patent No. 1782087 only displays advertising content on a specific digital signage selected by an advertiser based on the identification information of the digital signage and the authentication information of the digital signage that will display the advertising content, and does not describe, suggest, or imply any technical features that enable anyone to create and manage high-quality content in the cloud by creating new content for specific content based on AI proposed in the present invention, and transmit and display new content on at least one digital signage through a network.

[0017] The present invention was created to solve the above problems, and its purpose is to enable efficient use of digital signage installed in various locations by constructing a digital signage integrated network that connects multiple digital signages through a network and manages and operates them in an integrated manner.

[0018] The purpose of the present invention is to provide a method and system for enabling a user to diversify the viewing experience of a single piece of content by generating new content on the cloud using a generative AI based on specific content provided by a content provider and transmitting and displaying the new content on a digital signage desired by the user.

[0019] The purpose of the present invention is to support the creation of content even by non-experts through generative AI that can create new content based on specific content by individually classifying and learning related information related to content, such as environmental characteristics including weather, temperature, humidity, season or a combination thereof of a location where digital signage is located, human characteristics including trends, age groups, interests or a combination thereof of users of content, or usage characteristics including public interest information, disaster information or advertising information to be provided through the content.

[0020] The purpose of the present invention is to enable a user terminal to access a content server on the cloud, generate new content through generative AI, and provide the content to a specific digital signage of a digital signage integrated network, thereby effectively providing content to each digital signage without having to build a separate server.

[0021] The purpose of the present invention is to enable a user terminal to access a content server on the cloud and control the power on / off, dimming, and color temperature of a specific digital signage in a digital signage integrated network, thereby enabling each digital signage to be operated in an optimal manner adapted to the variable environment of the installation location.

[0022] A method for providing AI-based content through construction of a digital signage integrated network according to one embodiment of the present invention comprises: a content data receiving step of receiving content data including content, information related to the content, or a combination thereof from a user terminal at a content server; a new content generation step of automatically generating new content based on the received content data by utilizing generative AI according to a user request or a predetermined scenario at the content server; and a content transmission step of transmitting, at the content server, new content to at least one digital signage; characterized in that, without going through a separate content production process, modified new content automatically generated by utilizing the generative AI based on the received content data is transmitted to a digital signage desired by the user and provided.

[0023] The above digital signage integrated network is characterized in that the plurality of digital signages are connected to the network and are managed and operated in an integrated manner, and the at least one digital signage is connected to the content server through the digital signage integrated network, and the content server is configured to transmit the newly created content to the at least one digital signage according to a command from the user terminal.

[0024] The above AI-based content providing method further includes a step of controlling power on / off, dimming, color temperature, or a combination thereof for a specific digital signage of the digital signage integrated network according to a command received from a user terminal or a predetermined schedule at the content server; wherein at least one digital signage among the plurality of digital signages is configured to operate by receiving power through PoE (power of ethernet).

[0025] The above content data is characterized in that, in addition to the content received from the user terminal, it further includes content creation additional information including environmental characteristics including weather, temperature, humidity, or season of the location where each digital signage is located, personal characteristics including trends, age groups, or interests of users of the content, or usage characteristics including public interest information, disaster information, or advertising information to be provided through the content.

[0026] The user terminal can request the generative AI to create new content while providing the content data to the content server, and the content server provides the new content created in response to the request of the user terminal to the user terminal before it is displayed on the corresponding digital signage, and the user terminal and the content server exchange the content data and the created new content through a mutual script or conversation.

[0027] The above-mentioned generative AI is characterized in that it is configured to individually classify and learn environmental characteristics, human characteristics, and utilization characteristics of the content generation additional information based on the content and related information related to the content, thereby generating new content that reflects the individual characteristics of the content generation additional information to a specific content.

[0028] The above content transmission step is characterized in that it further includes a resolution adjustment step of adjusting the new content created in the content server to a resolution for at least one digital signage.

[0029] The above content server is built on a cloud and generates new content through the generative AI according to a command received from the user terminal or a predetermined schedule, and provides it to a specific digital signage of a digital signage integrated network, and the generative AI is characterized in that a user inputs new input data into the model of the specific generative AI through the user terminal, using a model of a specific generative AI that is built and provided by a cloud service provider existing on the cloud, and trains the model.

[0030] In addition, the AI-based content provision system through the construction of a digital signage integrated network according to one embodiment of the present invention is characterized by including a memory storing a program for performing each of the above methods; and a processor configured to execute the program stored in the memory.

[0031] The present invention, configured as described above, has the effect of efficiently utilizing and operating digital signage by constructing a digital signage integration network that integrates multiple digital signages installed in various locations and transmitting and displaying content for information transmission, including advertisements, to each digital signage.

[0032] In addition, the present invention has the effect of increasing the effectiveness of information delivery and the usability of digital signage by diversifying new content based on the content by creating new content for specific content and displaying it through digital signage to attract people's attention.

[0040] Hereinafter, various embodiments of the present invention will be described in detail with reference to the attached drawings. Specific structural and functional descriptions of the embodiments disclosed in the specification or application of the present invention are merely illustrative for the purpose of explaining embodiments according to the present invention, and unless otherwise defined, all terms used in this specification, including technical or scientific terms, have the same meaning as commonly understood by a person of ordinary skill in the art to which the present invention pertains. Terms defined in commonly used dictionaries should be interpreted as having a meaning consistent with the meaning they have in the context of the related technology, and shall not be interpreted in an ideal or excessively formal meaning unless explicitly defined in this specification.

[0041] FIG. 1 is a diagram for explaining an AI-based content provision system through construction of a digital signage integrated network according to one embodiment of the present invention.

[0042] As illustrated in FIG. 1, an AI-based content provision system (10) through construction of a digital signage integrated network according to one embodiment of the present invention is configured to include a content server (100) and a database (400), and is configured to allow a user to access the content server (100) from a user terminal (200), create new content, and then transmit the created new content to a specific digital signage (300).

[0043] The above content server (100) is a cloud-based platform (server) configured to efficiently manage and operate multiple digital signages (300) installed and dispersed throughout the network through a digital signage integration network. The present invention provides a cloud-based content server, enabling effective provision of content to each digital signage without the need for a separate standalone server. However, it is reasonable to consider that constructing a standalone content server is also within the scope of the claims of the present invention.

[0044] The above content server (100) is basically configured to receive content from a user terminal (200) provided by a content provider and transmit and display the content on at least one digital signage (300) desired by the user (or content provider).

[0045] In addition, the content server (100) is configured to apply content received from a user terminal (200) to a generative AI to generate new content (i.e., new content) based on the content and transmit it to at least one digital signage (300) desired by the user.

[0046] In other words, rather than repeatedly displaying only specific content through digital signage (300), the content server (100) generates various new content based on the specific content and displays them through digital signage (300), thereby diversifying the specific content and attracting the attention of viewers (general users). This can expand and enhance the effectiveness of information delivery.

[0047] Additionally, the content server (100) transmits new content to the digital signage (300) desired by the user according to a schedule so that it can be displayed on each digital signage (300).

[0048] In addition, the content server (100) transmits the content or new content to digital signage (300) first when it is urgent public information related to a natural disaster, so that it can be displayed with priority over other content.

[0049] At this time, the content server (100) transmits disaster-related content to user terminals (smartphones) used by general users located adjacent to a specific digital signage in conjunction with a mobile communication service provider. In other words, the content server (100) is configured to transmit disaster-related content to users subscribed to the content server (100) in conjunction with the digital signage. In this case, this includes transmitting content related to public information using the CBS (cell broadcasting service) function of the user terminal.

[0050] The above-mentioned generative AI is configured to receive content generation additional information to be reflected in the above-mentioned specific content, or to generate new content (new content) based on specific content according to a pre-determined scenario, which will be described in detail with reference to FIG. 4.

[0051] The above user terminal (200) enables a content provider to display content on a desired digital signage (300) remotely through a content server (100), and by downloading and executing an application program for driving the digital signage (300) from the content server (100), the user can freely control the digital signage (300).

[0052] At this time, the user terminal refers to a wired or wireless communication terminal equipped by the user, including a dedicated terminal, a smartphone, a tablet PC, etc.

[0053] A content provider can control the display of various contents through at least one digital signage (300) by accessing a content server (300) through a user terminal (300) to create new contents, select a desired digital signage to display the created new contents, or set a schedule for displaying the contents.

[0054] The above digital signage (300) comprises a screen (e.g., an LED display board) for displaying content and is installed in various locations to convey information. Furthermore, the digital signage (300) can be installed in various locations, such as rooftops of large buildings, public spaces such as subway stations, and indoor and outdoor areas of buildings.

[0055] Here, the content server (300) is connected to at least one digital signage (300) through a network, and registers digital signage information including location information where the digital signage (300) is installed, device information related to resolution or screen configuration (type of display panel), and identifier of the digital signage (300) in a database (400) to perform the function of managing and operating the digital signage (300).

[0056] The above database (400) stores and maintains the generative AI model, content data, and digital signage information generated by the content server (200). Here, the database (400) may be a database built on the cloud or a separate standalone or custom database.

[0057] The present invention involves using a specific generative AI model built and provided by a cloud service provider existing on the cloud, allowing a user to train the model by providing / inputting new input data to the specific generative AI model through a user terminal, and then creating and using a new generative AI.

[0058] The above digital signage (300) is connected to a network using PoE (power of ethernet), PoE+, or PoE++, and can be configured to operate by receiving power from the network. The PoE method, including PoE+ and PoE++, refers to a technology that can transmit and receive power and data together through a cable (Ethernet cable) used for data traffic. Since it is a technology defined by a standard, a detailed description is omitted.

[0059] However, for a detailed explanation of the PoE-based digital signage integrated network, refer to Figure 2.

[0060] FIG. 2 is a diagram for explaining an AI-based content provision system through a PoE-based digital signage integrated network according to one embodiment of the present invention.

[0061] As illustrated in FIG. 2, a PoE-based digital signage integrated network according to one embodiment of the present invention is structured such that each digital signage is connected to a plurality of PoE switches constituting the network.

[0062] Each PoE switch includes at least one Power Source Equipment (PSE) to supply commercial power to each digital signage, and each digital signage has a Powered Device (PD).

[0063] Each digital signage connected to the Ethernet port of the PoE switch transmits and receives data and also receives power through the PoE switch.

[0064] The content server can control this power supply, and the content server further includes a function to turn the power on and off, or control the dimming or color temperature of each digital signage. That is, when the PSE of each port equipped in the PoE switch is turned off from the content server, the power is turned off, and when it is turned on, the power is turned on, so that power control is possible by controlling the port of each PoE switch. In addition, it is possible to control the dimming of each digital signage by adjusting the current supply from the PSE. In addition, if the digital signage is configured to change the color temperature through a combination of the arrangement of LED light sources, the content server is configured to be able to adjust the color temperature through power control according to the arrangement of the LED light sources.

[0065] Therefore, by enabling the user terminal to access a content server on the cloud and control the power on / off, dimming, and color temperature of a specific digital signage in the digital signage integrated network, each digital signage can be operated in an optimal manner adapted to the variable environment of the installation location.

[0066] FIG. 3 is a diagram for explaining the overall operation of an AI-based content provision system through construction of a digital signage integrated network according to one embodiment of the present invention.

[0067] As illustrated in FIG. 3, a content server (100) according to one embodiment of the present invention receives content data including specific content, information related to the content, content creation additional information for creating new content, or a combination thereof, from at least one user terminal (200).

[0068] That is, the user terminal (200) transmits content data to the content server (100) to request the creation of new content (new content) based on the specific content.

[0069] Information related to the above content refers to textual information describing the content. For example, if the content advertises a specific product, it includes the type of product (e.g., cosmetics), the advertising model (e.g., a specific celebrity), and the target age group.

[0070] The above content creation additional information includes environmental characteristics including weather, temperature, humidity, season or a combination thereof of the location where the digital signage (300) desired by the user is located, human characteristics including trends, age groups, interests or a combination thereof of the users of the content, or utilization characteristics including public interest (campaign) information, disaster information or advertising information to be provided through the content.

[0071] Additionally, a user can access a content server (100) via a user terminal (200) and select a digital signage (300) to display content. The selection is made via a command line, graphical interface, or chatbot.

[0072] To enable a user to select a digital signage, the content server (100) displays a digital signage map including location information, identification information, or a combination thereof where a plurality of digital signages (300) are installed through a user interface, and allows the user to select at least one digital signage located in an area or place where content is to be displayed from the digital signage map.

[0073] The above digital signage map is map data displaying digital signage (300) by region and location. The above map is preferably presented graphically, but can also be presented in text or sound.

[0074] Additionally, the content server (300) supports the ability to set a schedule (time) for displaying content. To this end, the content server (300) displays operational information for digital signage, including the time at which content is displayed, through a user interface for each new content selected by the user, allowing the user to set a schedule. Meanwhile, each new content can be scheduled in advance to be output in real time as soon as it is created.

[0075] Afterwards, the content server (300) transmits new data to each digital signage (300) through the network according to a schedule so that it can be displayed on each digital signage (300).

[0076] Of course, if another content provider is displaying its content through the digital signage (300), and another content provider wishes to display its content through the specific digital signage (300), the content server (100) sets a schedule to avoid the time when the content of the specific content provider is displayed, or sets a schedule to display both contents through an agreement between the two content providers. Of course, the design prioritizes each content provider and gives priority to the content provider with the highest priority.

[0077] The above content creation additional information may be received separately when new content is to be created. That is, it is preferable that the user transmit content data excluding the content creation additional information to the content server (100) and display it on the desired digital signage (300) according to a schedule, while requesting the creation of new content by transmitting the content creation additional information to the content server (100).

[0078] At this time, it is desirable for the content server (100) to provide new content to the user terminal (200) before transmitting it to at least one digital signage (300) desired (i.e. selected) by the user, so as to check whether there is a problem with the created content.

[0079] Afterwards, the user checks the new content through the user terminal (200) and, if he / she likes it, commands the new content to be transmitted to the desired digital signage (300).

[0080] In addition, when the above transmission command is received, the content server (100) transmits the new content to at least one digital signage (300) selected by the user so that it can be displayed. At this time, the transmission is configured so that the command can be executed immediately or according to a pre-set schedule.

[0081] When the content server (100) receives content data containing content creation additional information, it applies the content data to a generative AI to generate new content based on the specific content. That is, a user can access the content server, provide information on content to be created through the generative AI via a script or chat, referencing the content creation additional information, and thereby acquire new content.

[0082] For example, if a specific content is an advertisement promoting a specific product (e.g., home appliances) through a specific model (e.g., a celebrity), and the content generation additional information includes environmental characteristics including summer (season) and human characteristics including retro (trend), the generative AI can generate new content based on the specific content by replacing the clothes worn by the specific model with retro summer clothes and replacing the background of the advertisement with a cool background such as the ocean.

[0083] The above generative AI will be described in detail with reference to Fig. 4.

[0084] Meanwhile, new content can also be generated based on user-preset scenarios.

[0085] For example, a user can set up a scenario where generative AI generates new content based on a specific content by generating content data that includes environmental characteristics, such as the season (winter) in December, and personal characteristics, such as interests related to Christmas or New Year's. The generative AI can then replace the model and background with those related to Christmas or New Year's to generate new content.

[0086] FIG. 4 is a diagram for explaining an embodiment of generative AI in an AI-based content provision system through construction of a digital signage integrated network according to one embodiment of the present invention.

[0087] As illustrated in FIG. 4, a generative AI according to one embodiment of the present invention is a model configured to input additional information including environmental characteristics, human characteristics, utilization characteristics, or a combination thereof, information and content related to content (specific content), and to generate new content based on the specific content by reflecting the additional information to the specific content.

[0088] The model presented in Fig. 4 uses a variational autoencoder, and in the present invention, it includes a diffusion model, a generative adversarial network (GAN), and a transformer-based configuration.

[0089] The variational autoencoder model described above uses neural networks called encoders and decoders. The encoder neural network maps input data to the mean and variance for each dimension of the latent space. It randomly generates a sample from a normal distribution, which represents a point in the latent space and represents a compressed and simplified version of the input data. The decoder neural network then takes this sampled point in the latent space and reconstructs it into data similar to the original input. A mathematical function is used to measure how well the reconstructed data matches the original data.

[0090] The above generative AI learns the environmental characteristics, human characteristics, and utilization characteristics of the additional information for content creation by individually classifying the content and related information related to the content based on text and images, respectively, through a clip encoder, which is a neural network that takes text or images as input, and embedding tokens for each.

[0091] Additionally, for specific content, each image is trained through a clip encoder neural network. The results of the encoder neural network are decoded through a decoder neural network, and then tokens embedded in each content-generated additional information are used to perform semantic classification to generate the final content. In other words, new content based on the specific content is generated by reflecting the individual characteristics of the content-generated additional information.

[0092] The above learning is performed based on text, images, videos, or a combination thereof, and learning can be performed by organizing learning data according to any field.

[0093] The above generative AI can be used by fine-tuning an existing commercially available model for content production to generate new content of the present invention.

[0094] FIG. 5 is a block diagram showing the core modules of a content server and the hardware structure of a content server in an AI-based content provision system through construction of a digital signage integrated network according to one embodiment of the present invention.

[0095] As illustrated in FIG. 5, a content server (100) according to one embodiment of the present invention is configured to include a content data receiving unit (110), a scenario setting unit (120), a digital signage selection unit (130), a new content creation unit (140), a new content provision unit (150), a content transmission unit (160), a content management unit (170), and a signage control unit (180).

[0096] The above content data receiving unit (110) receives content data from at least one user terminal (200). The above content data has been described with reference to FIG. 3, and thus is omitted here.

[0097] That is, the content data receiving unit (110) receives a request for creation of new content for specific content from at least one user terminal (200) by receiving content data including content creation additional information.

[0098] The above scenario setting unit (120) sets a scenario for creating new content. That is, a user can access the content server (100) via a user terminal (200) and set a scenario for creating new content for a specific content.

[0099] Ultimately, new content can be generated upon receiving a new content creation request or according to a pre-defined scenario. The above scenario has been described with reference to Figure 2, so it is omitted here.

[0100] The above digital signage selection unit (130) provides a digital signage map through a user interface, allowing the user to select the desired digital signage. The selection of the above digital signage has been described with reference to FIGS. 1 and 3, and thus is omitted here.

[0101] The above-mentioned new content generation unit (140) applies (inputs) the received content data or content data generated according to a scenario to a generative AI to generate new content based on the content data. In other words, new content is generated by reflecting content generation additional information on the received content (or specific content).

[0102] The creation of the above new content is described with reference to FIGS. 3 and 4, so it is omitted here.

[0103] The above new content provision unit (150) provides new content created to the user terminal (200). That is, it allows the user to check the new content and decide whether to display it through digital signage (300).

[0104] The above content transmission unit (160) is configured to transmit and display content or new content to at least one digital signage (300) selected by the user, and includes a schedule setting unit (161), a transmission command receiving unit (162), a resolution adjustment unit (163), and a content transmission unit (164).

[0105] The above schedule setting unit (161) sets a schedule (time) for displaying content (or new content) for each digital signage (300) selected by the user.

[0106] The above transmission command receiving unit (162) receives a command from the user terminal (200) to transmit content or new content to a digital signage (300) selected by the user.

[0107] For example, if a user who has confirmed new content provided through a new content provider (150) inputs a transmission command to transmit the new content through a user terminal (200), the user terminal (200) transmits the transmission command to a content server (100), so that the content server (200) that has received the transmission command transmits the new content to at least one digital signage (300). The transmission is performed according to a set schedule.

[0108] The above resolution adjustment unit (163) stores and manages resolution information for multiple digital signages (300) in advance, and adjusts the resolution of the digital signage (300) to be transmitted to the newly generated content. Of course, it is natural that existing content is also transmitted after being adjusted to the resolution of each digital signage (300).

[0109] Through this, the resolution adjustment unit (141) enables the content to be displayed at a resolution optimized for each digital signage (300), thereby enabling the viewing of clear content.

[0110] The above content transmission unit (164) transmits (sends) content with adjusted resolution or new content to at least one digital signage (300) selected by the user.

[0111] The above content management unit (170) stores and manages content and new content created based on the content in a database (400) for each content provider.

[0112] Meanwhile, if the content generation additional information included in the content data includes disaster information in its utilization characteristics, the content transmission unit (160) immediately transmits the content included in the content data to all digital signage (300) located in the area related to the disaster, thereby enabling general users in the area to quickly recognize the disaster. At this time, the content transmission unit (160) can also transmit the content to the user terminals of general users located in the area in cooperation with a mobile carrier.

[0113] The above signage control unit (180) is configured to include a power control unit (181), a dimming control unit (182), and a color temperature control unit (183). Based on information about the configuration status of each signage, the power supplied to each signage via PoE is controlled to be turned on and off, the dimming is controlled by controlling the intensity of the current supplied to each signage, and if each signage is configured to change the color temperature, the color temperature can be changed by controlling the power supplied to each signage via the PoE switch.

[0114] The above power control unit (181) controls a PoE switch provided in a content server on a user terminal or in a cloud according to a pre-established schedule, thereby instructing the PoE switch to turn on and off the PSE connected to a specific digital signage, thereby turning off the signage late at night or in the early morning, thereby saving power consumption. In addition, when a digital signage is installed indoors, the digital signage is turned off when no one is moving around in the building, thereby saving energy.

[0115] The above dimming control unit (182) is said to control the dimming of a specific digital signage by adjusting the intensity of the current supplied from the PSE port connected to the specific digital signage in the PoE switch through a function of controlling the PoE switch provided in the content server on the cloud in accordance with a user terminal or a pre-established schedule.

[0116] For example, digital signage using LEDs needs to control its brightness depending on the surrounding environment. If the surroundings are too bright, the digital signage must be brightened to ensure visibility. However, if the surroundings are dark, the digital signage can be lowered to maintain visibility. Furthermore, since digital signage can cause light pollution, adjusting its brightness over time can help reduce complaints about light pollution and conserve energy for efficient operation.

[0117] The above color temperature control unit (183) provides a function that allows the color temperature to be adjusted so that the digital signage can be in harmony with the characteristics of the location where the digital signage is located and other digital signage or billboards in the vicinity. In some cases, the color temperature is adjusted to further improve the visibility of the digital signage so that advertisements or information can be provided in clearer or more comfortable colors. In order to control the color temperature, it is necessary for the content server to control the on / off or current intensity of the power supplied from the PSE to each port of the PoE switch connected to each digital signage. In order to control the color temperature, multiple ports of the PoE switch can be connected to a specific digital signage. The multiple ports are each connected to individually supply power to an array of LED light sources provided in the digital signage. In this case, the content server can control the power supply to the array of corresponding light sources by turning the power supply on / off or controlling the current intensity for the multiple ports, thereby controlling the power supply to the corresponding light source, thereby enabling control to display a desired color temperature.

[0118] Additionally, the above content data and new content can be transmitted and received through mutual scripts or conversations between the user terminal (200) and the content server (100).

[0119] In addition, the hardware structure of the content server (100) is configured to include a processor (1000), memory (2000), a user interface (3000), a database interface (4000), a network interface (5000), and a web server (6000).

[0120] The above memory (2000) stores a program (application program) that performs a method for utilizing digital signage (300), and the processor (1000) is configured to execute the program to utilize digital signage (300).

[0121] The user interface (3000) provides input and output interfaces to the user by using a graphical user interface (GUI).

[0122] The database interface (4000) provides a storage interface between the database (300) and the hardware structure.

[0123] The network interface (5000) provides a network connection between a device held by a user (i.e., a user terminal) and the digital signage (300). The network interface (500) supports various types of network connections.

[0124] The web server (6000) provides a means for the user to access the content server (100) via a network. Most users can access the content server (100) by remotely accessing the web server.

[0125] The above-described configuration and method of utilizing digital signage (300) through each configuration may be implemented as computer-readable code on a computer-readable recording medium or transmitted via a transmission medium. A computer-readable recording medium is a data storage device capable of storing data that can be read by a computer system. Examples of computer-readable recording media include, but are not limited to, databases, ROMs, RAMs, CD-ROMs, DVDs, magnetic tapes, floppy disks, and optical data storage devices. The transmission medium may include a carrier wave transmitted via the Internet or various types of communication channels.

[0126] Additionally, the computer-readable recording medium can be distributed through a network-coupled computer system so that the computer-readable code is stored and executed in a distributed manner.

[0127] Additionally, at least one component applied to the present invention may include or be implemented by a processor (1000) that performs each function, and two or more of the components may be combined into a single component that may perform all operations or functions of the two or more combined components. Additionally, a portion of at least one component applied to the present invention may be performed by another component among these components. Additionally, communication between the components may be performed via a bus (not shown).

[0128] Accordingly, the AI-based content provision system through the construction of a digital signage integrated network according to the present invention is configured to store a program for performing each processing step of the AI-based content provision method through the construction of a digital signage integrated network in a memory (2000), and includes a processor (1000) configured to execute the program stored in the memory (2000).

[0129] Figure 6 is a flowchart illustrating a processing process of a method for providing AI-based content through construction of a digital signage integrated network according to one embodiment of the present invention.

[0130] As illustrated in FIG. 6, a procedure for utilizing multiple digital signages according to one embodiment of the present invention first performs a content data reception step in which a content server (100) receives content data including content, content-related information, and content creation additional information including environmental characteristics, human characteristics, and utilization characteristics from a user terminal (200) (S110).

[0131] That is, in the user terminal (200), content data is transmitted to the content server (100) to request the creation of new data.

[0132] Next, in the content server (100), a new content creation step is performed to create new content based on content data using a generative AI (S120).

[0133] The above new content creation step creates new content based on the content data when a new content creation request including content data is received.

[0134] Meanwhile, the new content creation step can generate new data based on a scenario previously set by the user. The process of generating the new data has been described with reference to FIGS. 3 and 4, and thus is omitted here.

[0135] Next, in the content server (100), a new content provision step is performed to provide new content created through the new content creation step to the corresponding user terminal (200) (S130).

[0136] The above new content provision step provides new content to the user terminal (200) so that the user can check it.

[0137] Next, the content server (100) waits for a transmission command for new content and a designation of a digital signage to be transmitted from a user terminal (200), and when a transmission command for new content is received (S140), a resolution adjustment step is performed to adjust the new content to the resolution of the digital signage (300) desired by the user (S150).

[0138] That is, the user terminal (200) performs a transmission command transmission step of transmitting a transmission command for the new content to the content server (100) according to the user's selection.

[0139] The digital signage (300) desired by the user is pre-selected, and the content server (200) performs a digital signage selection step to display a digital signage map to the user so that at least one digital signage can be selected.

[0140] Next, in the content server (100), a content transmission step is performed to transmit (send) new content adjusted to each resolution to each digital signage (300) desired by the user (S160).

[0141] The above content transmission step transmits the new content to at least one digital signage (300) according to a pre-set schedule. The schedule is set through the schedule setting step.

[0142] Meanwhile, if a transmission command for new content is not received (S140), the content server (100) does not transmit new content and creates new content again according to the user's selection (S110 to S130).

[0143] In addition, multiple new contents can be created in advance, and a schedule can be set for each new content so that each new content can be transmitted and displayed on digital signage (300) according to each schedule.

[0144] In this way, the present invention has the effect of efficiently utilizing and operating digital signage by constructing a digital signage integration network that integrates multiple digital signages installed in various locations and transmitting and displaying content for information transmission, including advertisements, to each digital signage.

[0145] In addition, the present invention has the effect of increasing the effectiveness of information delivery and the usability of digital signage by generating new content for specific content, diversifying new content based on the content, and displaying it through digital signage to attract people's attention.

[0146] In addition, although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and various modifications can be implemented by a person having ordinary skill in the art to which the invention pertains without departing from the gist of the present invention claimed in the claims, and such modifications should not be understood individually from the technical idea or prospect of the present invention.
