As shown, the video content providing server 100 for digital signage may include a communication module 110, a memory 120, a processor 130, a database 140, and an input module 150.

The communication module 110 communicates data with the connected server 100, the linked set-top box 200, and the content provider 400, respectively. The communication module 110 may be a device including hardware and software necessary to transmit and receive signals such as control signals or data signals through wired/wireless connection with other network devices.

A video content providing program for digital signage is stored in the memory 120. The digital signage video content providing program receives information on a category of video content to be provided through the digital signage set-top box as a user interest category from a user terminal that manages one or more set-top boxes for digital signage, and One or more keywords representing the characteristics of the video content are extracted from the video content to be transmitted to the digital signage set-top box through, and the number of occurrences of each keyword extracted from the video content and the category matched to each keyword A video content category is determined based on the determined video content category and a user interest category, and a set-top box playlist including at least one content to be provided to the digital signage set-top box is generated.

The memory 120 stores various types of data generated during execution of an operating system for driving the video content providing server 100 for digital signage or a video content providing program for digital signage.

In this case, the memory 120 collectively refers to a nonvolatile storage device that continuously maintains stored information even when power is not supplied and a volatile storage device that requires power to maintain the stored information.

In addition, the memory 120 may perform a function of temporarily or permanently storing data processed by the processor 130. Here, the memory 120 may include a magnetic storage media or a flash storage media in addition to a volatile storage device requiring power to maintain stored information, but the scope of the present invention is limited thereto. It does not become.

The processor 130 executes a program stored in the memory 140, and controls the entire process according to the execution of the digital signage video content providing program. Each operation performed by the processor 130 will be described in more detail later.

The processor 130 may include all types of devices capable of processing data. For example, it may refer to a data processing device embedded in hardware having a circuit physically structured to perform a function represented by a code or command included in a program. As an example of a data processing device built into the hardware as described above, a microprocessor, a central processing unit (CPU), a processor core, a multiprocessor, and an application-specific ASIC ( Integrated circuit), a field programmable gate array (FPGA), and the like may be covered, but the scope of the present invention is not limited thereto.

The database 140 stores or provides data necessary for a video content providing system for digital signage under the control of the processor 130. The database 140 may be included as a separate component from the memory 140 or may be built in a partial area of the memory 140.

2 is a block diagram showing the configuration of a system for providing video content for digital signage according to an embodiment of the present invention.

A system for providing video content for digital signage may include a server 100, one or more set-top boxes 200, a digital signage 300 connected to the set-top box, and a content provider 400.

The method of providing video content for digital signage may be implemented in the server 100 or the set-top box 200. In the method of providing video content for digital signage, the collection and analysis of video content is performed in the server 100, and the playlist generated as a result of the analysis may be provided to the set-top box 200. The server 100 may create and provide each playlist for each set-top box. In some cases, the same playlist may be shared among several set-top boxes.

The digital signage 300 refers to a display installed in a public place or a commercial space, and can provide various contents in combination with information and communication technology. The digital signage 300 corresponds to a display module and control may be performed through the set-top box 200.

The content provider 400 may be a server that provides video content. Since the video content directly provided by the content provider 400 does not include keyword analysis data or category information, the server 100 collects and analyzes the video content and then stores the analysis information including the playlist in a set-top box ( 200) can be provided.

3 is a flow chart showing the steps of a method for providing video content for digital signage according to an embodiment of the present invention.

The processor 130 receives information on a category of video content to be provided through the digital signage set-top box from a user terminal that manages one or more set-top boxes for digital signage as a user interest category (S110).

The user can directly register the user interest category through the user terminal. In addition, the user may input digital signage set-top box information including a set-top box registration number and set-top box installation location information in addition to the user interest category through the user terminal. For example, as illustrated in FIG. 4, the server 100 may receive a registration number of a set-top box and a user interest category, which is information on a video category of the set-top box, and store it in a database in order to manage information on the set-top box. The video category for each set-top box may be set as a single category, may include a plurality of categories, and when set to a plurality of categories, the weight of each category may be set differently. For example, as shown in FIG. 4, the user may set the video content to be provided with a 50% weight on each of the beauty category and the fashion category.

In order to register a set-top box, manage set-top box information, or register a user interest category, a user interface such as a separate web page or an application installed on the user terminal may be provided, and a user can input various information through this. have.

Referring back to FIG. 3, the processor 130 extracts one or more keywords representing characteristics of the video content through audio data extraction from the video content to be transmitted to the digital signage set-top box through the network (S120).

The processor 130 receives video content from individual video content providers. In this case, since the received video content does not include separate information such as a category or keyword, analysis is required. The processor 130 may extract voice data from oriental content and extract keywords from the extracted voice data. The processor 130 may utilize big data analysis and natural language processing to extract keywords from voice data.

The processor 130 determines a category of the video content based on the number of occurrences of each keyword extracted from the video content and a category matched to each keyword (S130).

The processor 130 may determine a category matched with the keyword having the largest number of appearances among the extracted keywords as the category of the corresponding video content.

In order to determine the category of video content, the present invention uses a keyword category matching table. As shown in Fig. 5, the processor 130 matches one or more keywords and categories extracted from the video content using a keyword category matching table listing keywords matching the category, and based on this, Decide.

In this case, the category keyword matching table defines a plurality of keywords included in each category. That is, several keywords known to be associated with a specific category (eg, beauty) may be registered in the keyword category matching table. Such a keyword category matching table is provided for each category.

Meanwhile, the administrator of the server 100 may update each keyword category matching table by selecting a specific category and entering, modifying, or deleting keywords belonging to the corresponding category in a table format.

Next, a detailed method of determining a category based on keywords extracted from video content will be described. As illustrated in FIG. 6, the server 100 may enumerate keywords extracted from video content, number of appearances in an image for each keyword, keyword category, and weight, and calculate a score. The keyword category may be extracted through the keyword category matching table described above with reference to FIG. 5.

The weight is a value set in proportion to the number of appearances in the image, and a method of calculating the weight may be modified according to the configuration of the server 100. In addition, by multiplying the number of appearances in the video for each keyword and the weight, a score indicating the priority of each keyword may be calculated.

When a category is determined for each keyword in FIG. 6 and a score is calculated, the server 100 may add up the scores for each category of video content. That is, the scores of each keyword are summed among the same categories, and the summed result is the same as the table of FIG. 7. The category of the video is determined as the category with the highest score, and in the case of FIG. 7, the beauty category received the highest score at 39.8. Accordingly, the server 100 may determine the category of the video as the beauty category.

In a method different from the method of calculating the weight in a single video content, the weight can be calculated according to the number of occurrences of keywords in a plurality of video content provided by the server 100. That is, keywords that appear more frequently in the entire video content have a greater influence on determining the category, and keywords that occur only within a single video can be weighted so that they have relatively little influence in determining the category. When the weights for each keyword are calculated, the server 100 may utilize the calculated weights when calculating scores for individual video contents.

Referring back to FIG. 3, the processor 130 generates a set-top box playlist including at least one content to be provided to the digital signage set-top box based on the determined category of video content and the user interest category. Do (S140).

The processor 130 may add the content to the set-top box playlist when the determined category of the video content is the same as the user interest category.

For example, as shown in FIG. 8, a digital signage set-top box installed in a beauty salon may be registered as 50% beauty and 50% fashion as user interest categories. In this case, the playlist automatically generated by the server 100 may include 50% of video content classified into a beauty category and video content classified into a fashion category. That is, if the user initially registers the user interest category of the set-top box once, after that, the server 100 automatically classifies the video content supplied by a third party and automatically classifies the video content corresponding to the user interest category in the playlist. Will be added.

As another method of generating a playlist, the processor 130 calculates a similarity score between the determined video content category and the user interest category, and adds the content to the set-top box playlist when the calculated similarity score is equal to or greater than a preset reference value. can do. In this case, the similarity score is calculated based on the keyword category matching table, the number of occurrences for each keyword, and the weight for each keyword, and the weight for each keyword may be calculated according to a ratio of the occurrence of keywords in one or more video contents.

An embodiment of the present invention may also be implemented in the form of a recording medium including instructions executable by a computer, such as a program module executed by a computer. Computer-readable media can be any available media that can be accessed by a computer, and includes both volatile and nonvolatile media, removable and non-removable media. Further, the computer-readable medium may include a computer storage medium. Computer storage media includes both volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data.

Although the methods and systems of the present invention have been described in connection with specific embodiments, some or all of their components or operations may be implemented using a computer system having a general-purpose hardware architecture.
