Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for providing recommended contents of a set-

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a content providing method of a shopping data broadcast in a television apparatus connected to a set-top box, and more particularly to a content providing method of a T-Commerce (T-commerce) service.

Traditionally, home shopping broadcasting has been provided through television broadcasting. Television broadcasting uses the entire screen of the receiver. The broadcast program contents produced by the broadcasting company are broadcast through the entire screen of the receiver, and the viewer likewise views the home shopping broadcast on the entire television screen.

On the other hand, digital television broadcasting technology improves conventional broadcasting technology that only provides broadcast contents unilaterally through a television screen. In particular, we created an environment in which users interact with each other in real time. In particular, in the case of a TV data broadcasting home shopping for a user purchase event, an interactive relationship with a user is more important. In general, the user relies on a remote controller to select an exposed tree or list. A conventional user interface of a television broadcasting or data broadcasting home shopping includes a trigger area for displaying broadcast contents reproduced in real time or VOD on a full screen and reacting through an information area providing a series of information and a remote controller.

In such a conventional user interface, there is a problem that the broadcasting area is invaded by the information area, thereby causing the problem that the completeness of the broadcasting contents is infringed (phenomenon that the broadcasting screen is hidden) It is difficult to distinguish broadcasting and data broadcasting from viewers, that is, it is difficult to distinguish between television broadcasting home shopping and data broadcasting home shopping. In the prior art, it is difficult to reflect unique characteristics of various viewers such as viewing history of users or purchase history, Technical limitations, since only one broadcast content is broadcast on the screen, there is a problem that viewers who are less interested in broadcast content easily deviate from the channel.

The inventors of the present invention have sought and discussed various methodologies for solving such problems technically and efficiently. It was a study of how attractive to more viewers could attract more viewers' purchase events without allowing more viewers to leave home shopping.

As part of such research, we reviewed the RFM model. The RFM model is known as a data analysis method that selects customers who are likely to buy by classifying customers based on the transaction's recency, frequency of transaction, and monetary value. As a financial technique using this RFM model, Korean Patent Laid-Open No. 10-2010-0061098 constructed RFM information for a customer and proposed a royalty service of a credit card merchant using the RFM information. However, the application of the RFM model is unknown in the data broadcasting field. The inventors of the present invention have long studied how an RFM model can be applied in a data broadcasting home shopping and completed the present invention.

 It is an object of the invention to provide a new user experience to prevent more viewers from leaving the data broadcasting home shopping. This goal is embodied by a user interface that is created by structuring a user's specific viewing pattern by applying the RFM model.

In order to achieve this purpose, it is necessary to be able to clearly grasp which viewers have certain viewing patterns. The present invention further elaborates the customized promotion provided in T-commerce data broadcasting by embodying such contents.

On the other hand, other unspecified purposes of the present invention will be further considered within the scope of the following detailed description and easily deduced from the effects thereof.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may obscure the subject matter of the present invention.

In the present specification, the term " T-commerce " is defined as a data broadcasting service capable of conducting a series of commercial transactions including searching for goods information, purchasing, and settlement through digital TV. In the present invention, unless otherwise specified, the expression " home shopping broadcast " is specified as a home shopping broadcast provided by T-commerce data broadcast.

In the present specification, the term " content area " means an area including a region where a TV application and a home shopping broadcast content are displayed and an area where an event is announced in a home shopping broadcast user interface. The " screen area " refers to an area that is not a content area in the home shopping broadcasting user interface and that becomes a background skin of the content area.

<Data broadcasting home shopping service system>

1 schematically shows a network system configuration of the present invention. This network system is limited to conceptually explaining how the T-commerce data broadcasting service is systematically provided, and does not represent all networks related to TV broadcasting.

A set-top box 10 is connected to the digital TV 1, and data transmission / reception with the service server 20 is performed via the set-top box 10. When the digital TV 1 is connected to the service server 20 via the set top box 10, the service server 20 receives the unique identifier (ID: SAID) from the set top box 10, And obtains the user information corresponding to the ID of the set-top box 10 by inquiring the external or internal subscriber information management system. The set-top box 10 is usually connected to the digital TV 1 through a cable. The set-top box 10 and the service server 20 are connected via a network medium for executing TV broadcasting and data broadcasting. It includes wired and / or wireless networks. Preferably, a cable for data transmission / reception connected to the service server 20 may be connected to the set-top box 10 by entering the house. The remote controller 5 executes a control command for operating the digital TV 1. [

The service server 20 transmits the contents of the data broadcasting home shopping to the digital TV 1. [ The service server 20 may have various databases in managing data broadcast contents and resources. The database 21 may be a VOD content database. The database 23 may be a product information database. The database 25 may be a user rating database. Also, the database 27 may be a recommended content database, and the database 29 may be a screen content database. Although not shown in the drawings, a database for recording logs, a database for recording billing and settlement information, and the like may be further included. These databases may be located in a system managed by the service server 20, or may be located in a repository managed by an external server.

In addition, the service server 20 further includes storage means, means for managing and processing data, transmitting and receiving data, means for processing communication with an external device or external system, and means for authentication and security, This may include various hardware devices, server devices, and software. In the case of a series of procedures, such as a process for authenticating subscriber information matching a set-top box ID, a process for determining recommended content, and a process for making a payment transaction in connection with an external financial institution, It can be executed through communication with an external server and devices, if it resides or needs to be transmitted to the outside.

FIG. 2 conceptually illustrates a time point at which a user interface of a T-commerce data broadcast according to the present invention is output through a screen of a digital TV. Generally, when the television apparatus is turned on, the television broadcast screen 1a will normally be turned on. It may be a terrestrial television broadcast channel or a cable or satellite broadcast channel. The user, that is, the viewer, can transmit the control command so as to switch to the data broadcasting screen 1b by operating the remote controller 5. [ In the present invention, the user selects a T-commerce data broadcast requesting a TV home shopping VOD with data broadcasting. Thus, the user interface of the present invention is output through the digital TV screen.

<T Commerce  The user interface 100 of the home shopping broadcast>

FIG. 3 shows a schematic configuration example of a user interface 100 of a home shopping broadcast according to a preferred embodiment of the present invention. The hatched portion in the figure is the screen area 110. [ The area surrounded by the screen area 110 becomes a content area. The content area may include a TV application area 130, 140, 150 and an event area 160 having a plurality of independent functions and independent areas as well as a VOD area 120 in which home shopping broadcast contents are reproduced. Also, the content area may include a general mark (not shown) that provides information only as text and / or images. The general cover may include an address of a website, an order phone number, a consultation telephone number, price information, product information, remote controller trigger guide information, weather information, a data broadcast home shopping channel, and other guidance text or images. This can be seen by way of example through the scenarios of FIGS. 7 through 9.

In the case of a typical television home shopping broadcast, the broadcast content is reproduced on the TV while occupying the entire screen. However, in the home shopping broadcast of the present invention, it is preferable that the VOD area 120 in which the broadcast content is reproduced has a size of 30 to 50% of the entire screen of the TV in a preferred embodiment. By configuring the VOD area 120 to be 50% or less as in the above embodiment, the viewer can intuitively distinguish the difference between the data broadcast home shopping of the present invention and the general TV broadcast home shopping. If the VOD area 120 is less than 30%, it is possible to experience a side effect of deteriorating the visibility of broadcasting.

In this embodiment, the user interface 100 having the VOD area 120 in the range of 30 to 50% of the TV screen when connected to the service server can be displayed as a default. It goes without saying that the user can be instructed to view the full screen by using the remote controller button after the user interface 100 is displayed.

As shown in FIG. 3, the home shopping broadcasting user interface 100 of the present invention may include a plurality of TV application areas having independent functions and independent areas.

The first TV application area 130 may be a real-time ranking list of home shopping broadcasts. For example, it is possible to indicate the order of sale of the best-selling goods today through the data broadcasting home shopping. In some preferred embodiments, the VOD content of the selected product as a full screen may be reproduced as a new user interface when selecting a product included in the list. In this case, the list functions as a data broadcasting home shopping channel. In another preferred embodiment, when a product included in the list is selected by a remote controller, the user interface may be changed to another predetermined user interface. The changed user interface may be a user interface providing more detailed information about the selected product.

The second TV application area 140 may be a recommended content displayed in the content area. In the case of the first TV application area 130, the list may be displayed. In contrast, the recommended content in the second TV application area 140 may be constituted by text and / or images of recommended product information by recommendation logic . Preferably, the user information specified by the ID of the set-top box can be used.

When a recommendation commodity displayed in the second TV application area 140 is selected by the remote controller, it is possible to display a plurality of recommendation contents lists preferably by using another user interface of the digital TV.

The third TV application area 150 may display the merchandise planning content predetermined by the service server. Or may be preset reference product information in other ways.

The type and arrangement of the TV app shown in Fig. 3 can be variously modified. Particularly important in the preferred embodiment of the present invention is that recommended content to which a later described RFM model is applied is provided through at least one of the content areas of the home shopping user interface 100. [ The recommendation content may be a promotion event that is registered in advance for a good customer or a promotional event that is registered in advance for a riskant customer.

Fig. 4 shows an example of such a conceptual principle in more detail. When a viewer requests a home shopping broadcast using a remote controller, the broadcast request is transmitted to the service server 20 via the set-top box 10, and the ID of the set-top box 10 may be transmitted to the service server 20 .

The service server 20 identifies the set-top box 10 ID. The service server 20 can obtain user information by inquiring the user information database residing outside or inside the service system. It is also possible to inquire the rank of the set-top box ID in the user class database (not shown) for each set-top box ID. The service server 20 receiving the viewer's request can extract the VOD broadcast content from the VOD broadcast content database 210. [ In addition, the above-described plurality of TV applications can be extracted in the databases 230 and 270 and the like. In addition, the screen contents can be extracted from the screen contents database 290. [ Each of the broadcast content, the TV application, and the screen content is positioned at a position allocated by the home shopping broadcast user interface 100 and is transmitted to the digital TV.

< RFM  Establishment of user class database by model>

5 is a diagram schematically showing a flow of a dynamic content providing method according to a preferred embodiment of the present invention.

First, the service server providing the data broadcasting home shopping service collects the viewing history log in the ID of the set-top box (S110). The history log may include time information of the user accessing the service server, cumulative viewing time information, and viewing date information.

Next, the history log is profiled according to the evaluation result according to the RFM model to classify the customer group to construct a user class database (S120).

The RFM (Recency, Frequency, Monetary) model according to the present invention evaluates the viewing last rating factor, viewing frequency rating factor and viewing frequency rating factor for data broadcasting home shopping by set-top box ID using the collected history log And modeling the evaluation result as a spatial coordinate concept.

The viewing last rating factor relates to a first profiling that evaluates how recently a user has watched (recency). The viewing frequency rating factor relates to a second profiling that evaluates how often a user has watched (frequency). And the number-of-views evaluation factor relates to a third profiling that evaluates how monetary is the total time the user has watched.

The first profiling according to an embodiment of the present invention divides a preset predetermined period into N (N is an integer greater than 1) intervals, and calculates a score from 1 to N according to which interval the user's recent viewing belongs And a process of giving a higher score to a user as the audience has been watching recently. For example, if the user's recent viewing was less than 7 days, the user would be given 5 points. If the user's viewing time was less than 7 days, the user would be given 28 points. In case of exceeding the work day, one point can be given.

The second profiling according to an embodiment of the present invention divides a viewing frequency of a user within a preset predetermined period into M (M is an integer larger than 1) intervals, and according to which section the user's viewing frequency belongs, M, and giving a higher score as the viewing frequency is higher. For example, if the viewing frequency of the user is divided into five periods from 0 to 9, from 10 to 19, from 20 to 34, from 35 to 49, and from 50 to 100 during the updating period described above and if the viewing frequency is 0 to 9 1 point, and 5 points for 50 to 100 points.

The third profiling according to an embodiment of the present invention divides the total cumulative viewing time of the user into L sections (L is an integer greater than 1) within a preset time period, and divides the total cumulative viewing time of the user into L Accordingly, a score ranging from 1 to L may be given, and a higher score may be given as the total viewing time is increased. For example, the total cumulative viewing time of a user in a month is sorted in descending order and divided into five groups of 20%, 5 points for the top 20% group having the largest cumulative viewing time, One point can be assigned to the lowest 20% group.

The evaluation result of the RFM model can be expressed by a spatial function such as RFM (n, m, l). N is the first evaluation score, m is the second evaluation score, and l is the third evaluation score.

The results of the RFM evaluation are schematically illustrated in FIG. If the user corresponding to a certain set-top box ID has a spatial coordinate of (n, m, l) larger than a predetermined reference, it can be classified as a good customer. Conversely, if the spatial coordinates of RFM (n, m, l) are smaller than the predetermined reference, it can be classified as a departure risk customer.

One unit block shown in FIG. 6 may be a group of users. In other words, it can be classified into groups assigned to each set-top box ID. As shown in FIG. 6, the customer, which is the RFM (5, 5, 5), which is the spatial coordinate at the top right of the evaluation result, can be regarded as the best customer class in the customer grouping. Customers with ratings of RFM (1, 1, 1) can be classified as escape risk customer ratings.

In FIG. 6, only the best customer class and the departure risk customer class are shown for the sake of understanding, but the customer class classification classified by the set-top box ID of the present invention is not necessarily limited thereto. Based on the evaluation results of the RFM model, customer characteristics can be derived and more detailed customer grouping can be generated. For example, by analyzing the RFM evaluation results, it is possible to classify a customer group that frequently watches a home shopping broadcast but does not watch for a long time, and a customer group that is not frequently viewed but has a long cumulative watch time.

In the above embodiment of the present invention, the user class database is constructed with RFM (n, m, l) values, but in other embodiments it may be constructed with values of (n, m). Not all set-top box IDs have their own unique ratings with unique scores. As described above, a plurality of set-top box IDs can belong to a common rating group. That is, the rating group of the set-top box ID may refer to the customer group.

Through such RFM profiling, a user class database can be constructed. Preferably, the user rating is set-top box ID rating because it is done by identifying the set-top box ID.

When the set-top box accesses the service server, the service server can identify the ID of the set-top box. Then, the service server inquires the rank of the corresponding set-top box ID in the user class database. If there is a recommended content corresponding to the rating searched in the recommended content database, it is extracted and placed in the content area of the home shopping broadcasting user interface, and the home shopping broadcasting content is transmitted to the set top box. At this time, the extracted recommended contents are pushed to the screen of the digital TV through the home shopping broadcast user interface according to the characteristics of the customer class (S130).

If the evaluation score corresponding to the ID of the set-top box connected to the service server is larger than a predetermined standard, the event registered as the good customer promotion can be set as the recommended content. On the contrary, if the evaluation score corresponding to the ID of the set-top box connected to the service server is smaller than a predetermined standard, the event registered as the escape risk customer promotion can be set as the recommended content.

<Screen Scenario>

7 to 9 are examples of specific screen scenarios of the home shopping broadcasting user interface 100 provided by the T-commerce data broadcasting according to the present invention. As such, the user interface 100 of the present invention can be configured and modified in various ways. The user screen scenario of FIG. 7 is illustrated in an exaggerated manner to help understand the explanation. Therefore, the size, proportion, text content, image, etc. of the screen will be variously modified and optimized.

When the remote controller of the viewer requests home shopping broadcasting, the home shopping broadcasting user interface 100 can be displayed as a TV screen as in the scenario of FIG. The hatched portion is the screen area 110, and the other part is the content area. The screen area 110 may surround the remaining content area of the user interface 100, and the combination of the remaining user interface areas may have a rectangular shape as a whole. Of course, the shape in which the screen area 110 surrounds the remaining area is not limited to the rectangular shape.

As described above, the VOD area 120 has a size ranging from 30% to 50% of the entire screen of the TV, and reproduces the broadcast content at a position that is most visible in the viewing view of the viewer. In the upper area 101 on the VOD area 120, a guide text may be displayed informing the viewer that the broadcast is a home shopping as a data broadcast, rather than a home shopping as a television broadcast. In addition, the left side area 125 of the VOD area 120 may display first additional information on a broadcast product while having a vertically rounded shape, ) Can display the second additional information. And a trigger area 129 for guiding the user to switch to the full screen by pressing the &quot; OK &quot; button on the remote controller.

On the right side of the VOD area 120, the first TV application area 130 can display a real-time ranking list of T-commerce data broadcasting. The recommended content recommended by the service server to the user may be displayed in the second TV application area 140 arranged on the lower left side of the first TV application area 130 and the recommended content may be displayed on the third TV application area 150 adjacent to the right side The merchandise planning content predetermined by the service server can be displayed. Event areas 161, 162, and 163 may be formed below the VOD area 120. The event area may include a button for guiding an event to be executed by the remote controller or for executing a predetermined event according to a selection command of the remote controller .

The bottom area 180 of the user interface 100 may include a web site address of the service server, an order phone number, a quick menu button, and the like. In the upper right area 190 of the user interface 100, an area, a weather icon, and temperature information specified by the ID of the set-top box can be displayed.

In a preferred embodiment of the present invention, the recommended content corresponding to the rating of the set-top box ID according to the spirit of the present invention may be displayed in the second TV application area 140 in the user interface 100 of FIG. It is needless to say that the recommended content of the present invention can be displayed in the area 120, the area 150 or the area 160.

Figure 8 illustrates another embodiment of the present invention. As can be seen in FIG. 8, the dynamic content 310 including the best customer promotion may be popped up on the user interface 100 and pushed to the user interface where the customer grouping is the best customer class. The Best Customer Promotion may include holding a special discount product exhibition, offering a special discount coupon, providing a special gift coupon, or providing a coupon for shipping.

Figure 9 illustrates another embodiment of the present invention. As shown in FIG. 9, the dynamic content 320 including the departure prevention promotion may be pushed to the user interface of the departure risk customer class. A departure-free promotion may include providing an attendance event that provides a deposit at attendance, providing a celebration event, and providing a discount coupon for escape prevention.

[Additional explanation and various modifications]

1. In order to execute the method of the present invention, it is necessary to collect the viewing history log for each set-top box ID and to manage it well by the file system.

When the set-top box 10 connects to the service server 20 and executes the TV application through the home shopping broadcasting user interface 100, the corresponding SAID is recorded. A viewing history log for each SAID is generated through a database including a merchandise log file viewed in the application, home shopping combination information, product information, and purchase information. Each generated log is collected by the data collector and stored in the distributed file system. Then, based on the DAISY logic, the SAID-based viewing history is profiled and then the SAID-specific user rating database is created. The DAISY system can be used as a set of management systems for customer classification logic performed by software in collecting structured and unstructured data, storing and analyzing logs and metadata, and classifying customers.

2. In the present invention, since the rating is set for each set-top box ID, the screen content displayed on the screen area 110 of the home shopping broadcasting user interface can be changed accordingly. The background skin displayed in the screen area 110 of the home shopping broadcasting user interface 100 can be configured to be changed according to the rating given to the set-top box ID. In this embodiment, both the visual content and the content of the home shopping broadcasting user interface 100 are configured differently according to the viewing history of each set-top box ID. This makes it possible to make home shopping broadcasting more intimate and more attractive to users.

The scope of protection of the present invention is not limited to the description and the expression of the embodiments explicitly described in the foregoing. It is again to be understood that the present invention is not limited by the modifications or substitutions that are obvious to those skilled in the art.
