Description

Home shopping broadcast providing device and home shopping broadcast providing method {APPARATUS AND METHOD OF PROVIDING HOME SHOPPING}

The present invention relates to a home shopping broadcasting providing apparatus and a home shopping broadcasting providing method, and more particularly, to a home shopping broadcasting providing apparatus and a home shopping broadcasting providing method capable of providing a plurality of home shopping contents through one home shopping channel.

In general, home shopping refers to a service provided through a broadcasting network or a communication network in order to sell a product. The home shopping provider transmits the home shopping content for the product to the receiver of the viewer through a predetermined channel (ie, the home shopping channel). Home shopping content may be transmitted to a receiver of a viewer using various methods such as digital terrestrial broadcasting, digital cable broadcasting, digital satellite broadcasting, analog broadcasting, DMB broadcasting, and IPTV. The receiver may include, for example, a device such as a television, set-top box, personal computer, and mobile communication terminal (ie, smart phone) with computing functionality for receiving and providing home shopping content.

The viewer can watch the home shopping content through the receiver and purchase the product if he / she wants to purchase it. The viewer may purchase a product that is broadcast through the home shopping content, for example, using a payment interface or telephone order displayed by the receiver.

However, the conventional home shopping has the following disadvantages.

Home shopping content is collectively transmitted to a plurality of viewers according to a predetermined broadcast schedule. That is, the existing home shopping content is provided to all viewers in the form of broadcast. Therefore, the home shopping contents are transmitted in a batch to a user who is not interested in the home shopping contents among the plurality of viewers, that is, a user who does not intend to purchase.

To improve this, for example, according to Korean Patent Application Publication No. 10-2016-0041437, filed by Katie Co., Ltd. and published on April 18, 2016, entitled "Method, System and Server for Providing Variable Home Shopping Channel," Analyze the propensity of the household based on subscriber information and viewing history of the household, and map one or more home shopping channel numbers per household and one or more logical home shopping channel numbers per household based on the analyzed household propensity, and mapping information A method for transmitting one of one or more logical home shopping channels mapped to a selected home shopping channel from a broadcast device to the broadcast device is disclosed.

However, the method disclosed in Korean Patent Application Publication No. 10-2016-0041437 discloses at least one of subscriber information including at least one or more of a subscriber's age, place of residence, and gender, and a viewing time, a viewing period, and a preferred product of a home shopping channel of a household. It is disadvantageous to analyze the propensity of the furniture based on the viewing history including one or more. In other words, in order to analyze the propensity of households, subscriber information is necessary.

<First Embodiment>

1 is a block diagram illustrating a home shopping broadcast providing apparatus and a plurality of receivers for receiving and providing home shopping content from a home shopping broadcasting providing apparatus according to a first embodiment of the present invention.

Referring to FIG. 1, the home shopping broadcasting providing apparatus 100 according to the first embodiment of the present invention may include a preference information processing unit 110, a first home shopping content specifying unit 130, and a second home shopping content specifying unit 140. ). Also, referring to FIG. 1, the home shopping broadcasting apparatus 100 according to the first embodiment of the present invention may further include a proximity information calculator 120 and a transmitter 150. 1, a plurality of receivers receiving home shopping content from the home shopping broadcasting providing apparatus 100, and more specifically, the first receiver 200-1 to the m-th receiver 200-m are illustrated. (Where m is a natural number of 2 or more).

The home shopping broadcasting providing apparatus 100 transmits content (hereinafter, also referred to as "home shopping content") to the first receiver 200-1 to the m th receiver 200-m through a broadcasting network or a communication network. The home shopping broadcasting providing apparatus 100 may provide a plurality of home shopping contents to the first receiver 200-1 to the m-th receiver 200-m. In particular, the home shopping broadcasting providing apparatus 100 may include, for example, first home shopping content designated according to a programming table; And at least one of the second home shopping contents designated from among the plurality of contents may be provided to the first receiver 200-1 to the m-th receiver 200-m. Alternatively, the home shopping broadcasting providing apparatus 100 may include first home shopping content; Second home shopping content specified among a plurality of contents; And at least one of third home shopping contents designated from among the plurality of contents may be provided to the first receiver 200-1 to the m th receiver 200-m.

The first receiver 200-1 to the m-th receiver 200-m may be, for example, any one of a set top box, a television, a personal computer, and a mobile communication terminal having a computing function. As used herein, "digital broadcast" refers to broadcast services in the form of digital terrestrial broadcast, digital cable broadcast, digital satellite broadcast, DMB broadcast, IP-TV, over the top (OTT), and VOD broadcast. Preferably, the first receiver 200-1 to the m-th receiver 200-m are bi-directional communication such as, for example, IP-TV, and are configured to transmit and receive data with the home shopping broadcasting providing apparatus 100. do. m may be any one of a total number of receivers that can receive and provide a home shopping channel and a predetermined number of receivers that can receive and provide a home shopping channel.

Referring to FIG. 1, the preference information processor 110 may include contents of contents for the first product group to contents of the nth product group received from the first receiver 200-1 to the m th receiver 200-m. Based on the viewing information, the preference information P (i, j) and the first receiver 200-1 to the j-th product group of the i-th receiver are changed while changing i from 1 to m and j from 1 to n, respectively. The number N (j) of receivers whose P (i, j) is equal to or greater than the threshold preference for the j th product group among the m th receivers 200-m is calculated. N is a natural number of two or more.

Hereinafter, an example of calculating P (i, j) and N (j) based on the above-described viewing information will be described in detail. However, this is merely illustrative, and a method of calculating P (i, j) and N (j) is provided. Is not limited to this.

FIG. 2 is a diagram exemplarily illustrating viewing information used to calculate preference information P (i, j) of the home shopping broadcasting providing apparatus according to the first embodiment of the present invention. For convenience of description, the viewing information is described using only the information received by the home shopping broadcasting providing apparatus 100 from the i-th receiver.

For example, when the home shopping channel is designated as channel 53, the viewing information of the i-th receiver includes a time at which a user input for selecting channel 53 is input at the i-th receiver, and a time at which a user input for leaving channel 53 is input. can do. The user input leaving channel 53 may include, for example, a user input for switching from channel 53 to another channel, and may also include a user input for turning off the power of the i-th receiver. Or a time difference, i.e., a time difference between the time when the user input leaving the channel 53 is input and the time when the user input selecting the channel 53 is input, instead of the time when the user input leaving the channel 53 is input. You may.

In addition, when there are a plurality of home shopping channels such as channel 53, channel 58, and channel 60, the viewing information of the i-th receiver may include a time when a user input for selecting each of the plurality of home shopping channels is input from the i-th receiver. The user input deviating from the channel 53 may include an input time.

3 is a diagram illustrating a product group used in the home shopping broadcasting providing apparatus according to the first embodiment of the present invention.

Referring to Figure 3, the first product group to the n-th product group, for example, the first product group is "water purifier", the second product group is "insurance", the third product group is "men's sportswear", The fourth product group is "electronics (computer)" and the nth product group is designated as "fashion article". Such a product group may be appropriately determined by the manager of the home shopping broadcasting providing apparatus 100, for example. For example, each of the first to n-th product groups may include one or more products. For example, a "fashion article" may include articles such as "bags", "sunglasses" and "scarves".

4 is a block diagram illustrating an exemplary configuration of a preference information processing unit of a home shopping broadcasting providing apparatus according to the first embodiment of the present invention.

Referring to FIG. 4, the preference information processor 110 includes a bounce rate calculator 111 and a preference information calculator 113.

The return rate calculating unit 111 may perform a first reference number representing the number of times the content for the j-th product group is provided for a first threshold time or more from a point in time selected by the i-th receiver, and the i-th receiver during the aforementioned predetermined time period. Calculate a second reference frequency, the number of times the contents for the j article group are provided above the first threshold time and below the second threshold time greater than the first threshold time, respectively, and are ratios of the second reference times to the first reference times; The bounce rate BR (i, j) for the j th product group of the i th receiver is calculated.

When the user input for selecting channel 53, for example, is input by the i-th receiver included in the viewing information, for example, the viewing information of the i-th receiver, shown in FIG. When comparing the programming table of the home shopping broadcasting for the above-described predetermined period, for example, it is checked whether the viewer of the i-th receiver watched the content of the product belonging to the product group belonging to the first product group or the n-th product group at a specific time period. do.

The predetermined time period may be any one of periods such as, for example, one day, one week, and one month. The first threshold time is set to eliminate the case where the contents for the j th product group are selected according to channel zapping. For example, the first threshold time is set to 2 seconds. The second threshold time is a time for confirming that the viewer of the i-th receiver has switched to the channel because he is not interested in the contents while watching the contents for the j-th product group. For example, the second threshold time is set to 10 seconds. For example, referring to the example of FIG. 4, when channel 53 is selected at 7:50:23 AM and leaves at 7:50:25 AM, a simple channel zapping is performed. If channel 53 is selected at 8:52:10 AM and leaves at 8:52:17 AM, the viewer of the i-th receiver switched channels because he was not interested in watching the contents of the j product group. .

The return rate calculating unit 111 first calculates the first reference number of times and the second reference number of times, and then a bounce rate for the jth product group of the i th receiver, which is a ratio of the second reference number of times to the first reference number of times. Calculate BR (i, j). The conveyance rate calculation part 111 calculates BR (i, j), changing j from 1 to m, respectively, and changing j from 1 to n, respectively.

BR (i, j) is information for calculating a preference for the j-th product group of the viewer of the i-th receiver. For example, if BR (i, j) is low, it means that the viewer of the i th receiver has a high preference for the contents for the j th product group. If BR (i, j) is high, it means that the viewer of the i th receiver has a low preference for the contents for the j th product group.

The preference information calculating unit 113 calculates P (i, j) based on BR (i, j) calculated through the conveyance rate calculating unit 111. For example, BR (i, j) and P (i, j) are calculated based on a relationship where P (i, j) = 1-BR (i, j).

However, this relationship is merely exemplary, and if BR (i, j) is high, P (i, j) is low, and if BR (i, j) is low, P (i, j) is high, P (i, j) may be calculated using other calculation schemes. For example, P (i, j) may be calculated based on a relationship where P (i, j) = 1-W (i, j) x BR (i, j). W (i, j) is, for example, the weight specified for the i th receiver and the j th product group.

For example, preference information P (1, 1) for the first product group of the first receiver to preference information P (1, n) for the nth product group of the first receiver are calculated, and the first product of the second receiver is calculated. The preference information P (2, 1) for the group to the preference information P (2, n) for the nth product group of the second receiver are calculated. Similarly, the preference information P (m, 1) for the first product group of the mth receiver to the preference information P (m, n) for the nth product group of the mth receiver are calculated.

The preference information processor 110 calculates the number N (j) of receivers whose P (i, j) is greater than or equal to the threshold preference for the j-th product group by using the threshold preference. N (j) is calculated by changing j.

FIG. 5 is a diagram exemplarily illustrating the number of receivers having preference information and threshold information for a specific product group and preference information used in the home shopping broadcasting providing apparatus according to the first embodiment of the present invention.

Referring to FIG. 5, the first product group to the nth product group, that is, each product group that is, for example, “water purifier” to “fashion article” and the first receiver 200-1 to m-th receiver 200-m For example, the preference information P (i, j) calculated by the preference information processing unit 110 is shown.

For example, for the first product group "water purifier", the first receiver 200-1 has 78% of preference information, and the m-th receiver 200-m has 33% of preference information. That is, P (1, 1) is 78% and P (m, 1) is 33%. If the critical preference information is assumed to be 70%, for example, the number of preference information is 70% or more for the “water purifier” among the first receiver 200-1 to the mth receiver 200-m, that is, N (1) is, for example, 243,342. Dog. Similarly, for example, for the nth merchandise group "fashion article", the first receiver 200-1 has 25% preference information, and the m-th receiver 200-m has 51% preference information. That is, P (1, n) is 25% and P (m, n) is 51%. Assuming the threshold preference information is, for example, 70%, the number of preference information is 70% or more for the " fashion article " among the first receiver 200-1 to the m-th receiver 200-m, that is, N (n) is, for example. 34,195.

For example, as described above, if BR (i, j) and P (i, j) satisfy P (i, j) = 1-BR (i, j), the first receiver 200-1 to the mth receiver ( The number of receivers having a carrier rate of less than 30% for the "water purifier" among 200-m) is calculated as N (1), and the "fashion article" among the first receiver 200-1 to the m-th receiver 200-m. For example, the number of receivers whose carrier rate is less than 30% is calculated as N (n).

Referring back to FIG. 1, the first home shopping content specifying unit 130 designates the first home shopping content provided through the home shopping channel. The first home shopping content designation unit 130 may designate the first home shopping content according to, for example, a predetermined schedule. That is, preferably, the first home shopping content designation unit 130 designates the content broadcasted live on the basis of a predetermined schedule as the first home shopping content. Alternatively, the first home shopping content designation unit 130 may designate a content having the maximum N (j) as the first home shopping content among a plurality of predetermined contents.

The second home shopping content designator 140 designates the second home shopping content provided through the above-described home shopping channel among the first content to the x-th content. Where x is a natural number of two or more. More specifically, the second home shopping content designation unit 140 changes the y from 1 to x, and the number of receivers N (C0, Cy) excluding the receiver calculated by overlapping with N (C0) among N (Cy) is maximum. The y th content to be designated as the second home shopping content provided through the home shopping channel. However, the products corresponding to the first home shopping content belong to the C0 product group, the first content to the xth content belong to the C1 to Cx product groups, respectively, and C0 to Cx are different natural numbers of 1 or more and n or less. to be.

The process of designating the second home shopping content by the second home shopping content designation unit 140 will be described in more detail as follows.

For example, when the first home shopping content is designated by the first home shopping content designation unit 130, a product corresponding to the first home shopping content, ie, the first, among the first receiver 200-1 to the m -th receiver 200-m, is defined. The number of receivers whose preference information for the C0 product group is greater than or equal to the threshold preference is calculated as N (C0). That is, the viewer corresponding to the N (C0) receivers means that the product corresponding to the first home shopping content is preferred.

Meanwhile, in receivers other than N (C 0) receivers among the first receiver 200-1 to the m-th receiver 200-m, the preference information for the C0 product group is less than the threshold preference. That is, a viewer corresponding to receivers other than N (C0) receivers among the first receiver 200-1 to the m-th receiver 200-m does not prefer a product corresponding to the first home shopping content. do.

Accordingly, in order to provide home shopping content other than the first home shopping content to viewers who do not prefer a product corresponding to the first home shopping content, the second home shopping content is designated from the first content to the x-th content.

The number of receivers in which the preference information P (i, j) of the first receiver 200-1 to the m-th receiver 200-m is greater than or equal to the threshold preference for the C1 product group to which the product corresponding to the first content belongs is N. It is decided by (C1). Similarly, the number of receivers in which the preference information P (i, j) of the C2 product group to which the product corresponding to the second content belongs among the first receiver 200-1 to the m-th receiver 200-m is equal to or greater than the threshold preference. Is set to N (C2). Similarly, the number of receivers in which the preference information P (i, j) of the Cx product group to which the product corresponding to the x-th content belongs among the first receiver 200-1 to the m-th receiver 200-m is greater than or equal to the threshold preference. Is set to N (Cx).

However, when calculating N (C1), the number of receivers whose preference information for the C0 product group is greater than or equal to the threshold preference is also included. Therefore, among the first receivers 200-1 to m-th receivers 200-m, among the receivers other than the receiver whose preference information for the C0 product group is equal to or greater than the threshold preference, the preference information P (i, Calculate the number N (C0, C1) of receivers where j) is greater than or equal to the threshold preference. Similarly, among the first receivers 200-1 to m-th receivers 200-m, among the receivers except the receivers whose preference information for the C0 product group is equal to or greater than the threshold preference, the preference information P (i, The number N (C0, Cx) of the receivers whose j) is equal to or greater than the threshold preference is calculated as the number N (C0, Cx) of the preference information P (i, j) for the Cx product group.

The second home shopping content designation unit 140 designates the content corresponding to the maximum among N (C0, C1) to N (C0, Cx) as the second home shopping content provided through the home shopping channel.

Referring back to FIG. 1, the apparatus for providing home shopping broadcasting according to the first embodiment of the present invention may further include the proximity information calculating unit 120.

The adjacency information calculating unit 120 changes the r and s from 1 to n based on P (i, j) calculated by the preference information processing unit 110 and the above-described threshold preferences, and the r product group and the first product. s Adjacency information A (r, s) representing correlation between product groups is calculated.

The high proximity between the r-th product group and the s-th product group means that viewers who prefer products belonging to the r-th product group are also more likely to prefer products belonging to the s-th product group. Similarly, the low proximity between the r-th product group and the s-th product group means that a viewer who prefers a product belonging to the r-th product group is unlikely to prefer a product belonging to the s-th product group.

FIG. 6 is a diagram illustrating proximity information used in the home shopping broadcasting providing apparatus according to the first embodiment of the present invention.

Referring to FIG. 6, for example, the proximity information A (1, 1) of the first product group "water purifier" and the second product group "insurance" is calculated as 0.64, and the first product group "water purifier" and the nth product. The adjacency information A (1, n) of the product group "fashion article" is calculated as 0.26.

The second home shopping content designation unit 140 may designate the second home shopping content more easily by using the proximity information A (r, s) described with reference to FIG. 6, for example.

For example, the product corresponding to the first home shopping content belongs to the "water purifier" product group, the product corresponding to the first content belongs to the "insurance" product group, and the product corresponding to the second content is the "men's sportswear" product. Assume that a product belonging to a group and corresponding to the third content belongs to a "electronics (computer)" product group, and a product corresponding to the xth content likewise belongs to a "fashion goods" product group.

 N (C0, Cy) may satisfy the relationship of N (C0, Cy) = [1-A (C0, Cy)] × N (Cy), for example. When N (C0, Cy) = [1-A (C0, Cy)] x N (Cy), referring to the adjacency information A (r, s) of FIG. 6 and N (j) of FIG. [1-A (C0, Cy)] × N (Cy) is calculated as (1-0.64) × 154,128 = 55,486 for the first content, and (1-0.35) × 75,732 = 49,225 for the second content. (1-0.73) x 132,563 = 35,792 for the third content, and (1-0.26) x 34,195 = 25,304 for the xth content.

Therefore, among the first to xth contents, the first content having the highest [1-A (C0, Cy)] × N (Cy) is designated as the second home shopping content.

However, such a relationship where N (C0, Cy) = [1-A (C0, Cy)] × N (Cy) is merely exemplary, and N (C0, Cy) is A (C0, Cy) and N ( Cy) may be calculated using another calculation method.

Referring back to FIG. 1, the home shopping broadcast providing apparatus 100 according to the first embodiment of the present invention may further include a transmitter 150.

The transmission unit 150 may include a first transmission mode for transmitting both the first home shopping content and the second home shopping content to the first receiver 200-1 to the m th receiver 200-m; And (i) if the P (i, C0) of the i-th receiver is greater than or equal to the threshold preference, transmit the first home shopping content to the i-th receiver, and (ii) P (i, C0) is less than the threshold preference and P (i, Ca1). Is greater than or equal to the threshold preference, transmits the second home shopping content to the i th receiver, and (iii) transmits the first home shopping content to the i th receiver if P (i, C0) and P (i, Ca1) are less than the threshold preference. To perform any one of the second transmission mode. However, the product corresponding to the second home shopping content belongs to the Ca1 product group.

For example, the transmitter 150 may transmit the multiplexed first home shopping content and the second home shopping content to the first receiver 200-1 to the m th receiver 200-m through the home shopping channel. Alternatively, the transmitter 150 transmits the first home shopping content and the second home shopping content to the first receiver 200-1 to the m th receiver 200-m through a physical channel, respectively, and the first receiver 200-. 1) to m-th receiver 200-m may select a suitable one from among the first home shopping content and the second home shopping content and provide it to the viewer. For example, the first receiver 200-1 to the m-th receiver 200-m may select one of the first home shopping content and the second home shopping content based on P (i, C0) and P (i, Ca1). It can be selected and provided to the viewer.

7 is a block diagram illustrating a home shopping broadcast providing apparatus according to a second embodiment of the present invention.

Referring to FIG. 7, the home shopping broadcasting providing apparatus 100 ′ according to the second embodiment of the present invention may include a preference information processing unit 110, a first home shopping content specifying unit 130, and a second home shopping content specifying unit ( 140 and a third content designation unit 160. In addition, referring to FIG. 7, the home shopping broadcasting providing apparatus 100 ′ according to the second embodiment of the present invention may further include a neighbor information calculating unit 120 and a transmitting unit 150 ′. The preference information processing unit 110, the proximity information calculating unit 120, the first home shopping content designating unit 130, and the second home shopping content of the home shopping broadcasting providing apparatus 100 ′ according to the second embodiment of the present invention. The designator 140 may include a preference information processor 110, a proximity information calculator 120, a first home shopping content designator 130, and the home shopping broadcast providing apparatus 100 according to the first embodiment of the present invention. It is substantially the same as the second home shopping content designation unit 140. Therefore, the preference information processing unit 110, the proximity information calculating unit 120, the first home shopping content designation unit 130, and the second of the home shopping broadcasting providing apparatus 100 ′ according to the second embodiment of the present invention. The description of the home shopping content designation unit 140 will be omitted.

The third content designation unit 160 designates the third home shopping content provided through the above-described home shopping channel among the contents other than the second home shopping content among the first content to the xth content. Where x is a natural number of two or more. More specifically, the third content designation unit 160 changes the number of receivers N (C0, Ca1 except for a receiver calculated by overlapping N (C0, Ca1) among N (C0, Cy) while changing y from 1 to x. , Cy) is designated as the third home shopping content provided through the home shopping channel. However, the products corresponding to the first home shopping content belong to the C0 product group, the products corresponding to the second home shopping content belong to the Ca1 product group, and the first to x th contents are the first to C x th Cx, respectively. C0 to Cx belong to the product group and are different natural numbers of 1 or more and n or less.

The process of designating the third home shopping content by the third content designation unit 160 will be described in more detail as follows.

For example, when the first home shopping content is designated by the first home shopping content designation unit 130 and the second home shopping content is designated by the second home shopping content designation unit 130, the first receiver 200-1 to the m-th. Among the receivers 200-m, the number of receivers whose preference information for the product corresponding to the first home shopping content, that is, the C0 product group, is equal to or greater than the threshold preference is calculated as N (C 0). In addition, among the receivers other than N (C0) among the first receiver 200-1 to the m-th receiver 200-m, preference information on a product corresponding to the second home shopping content, that is, a Ca1 product group is critical. The number of receivers above the preference is calculated as N (Ca1). That is, viewers corresponding to receivers other than N (C0) and N (Ca1) among the first receiver 200-1 to the m-th receiver 200-m may store goods corresponding to the first home shopping content and second home shopping content. This means that you do not prefer all of the corresponding items.

The third content designator 160 is configured to provide another home shopping content to viewers who do not prefer both the product corresponding to the first home shopping content and the product corresponding to the second home shopping content, from among the first content to the x-th content. 3 Specify home shopping content.

Among the first receiver 200-1 to the m-th receiver 200-m, the number of receivers whose product information corresponding to the y-th content, that is, the preference information on the Cy product group is greater than or equal to the threshold preference, is N (Cy). However, when N (Cy) is calculated, the number of receivers in which the preference information for the C0 product group is greater than or equal to the threshold preference and the number of receivers in which the preference information for the Ca1 product group is greater than or equal to the threshold preference are also included. Accordingly, the receivers excluding the receivers in which the preference information for the C0 product group is greater than or equal to the threshold preference among the first receivers 200-1 to 200m, and the receiver in which the preference information for the Ca1 product group is greater than or equal to the threshold preference The number N (C0, Ca1, Cy) of receivers whose preference information for the Cy product group is greater than or equal to the threshold preference is calculated.

An example in which the third content designation unit 160 designates the third home shopping content will be described using, for example, the proximity information A (r, s) described with reference to FIG. 6.

The product corresponding to the first home shopping content belongs to the "water purifier" product group, the product corresponding to the second home shopping content belongs to the "insurance" product group, and the product corresponding to the second content is the "men's sportswear" product Assume that a product belonging to a group and corresponding to the third content belongs to a "electronics (computer)" product group, and a product corresponding to the xth content likewise belongs to a "fashion goods" product group.

N (C0, Ca1, Cy) can satisfy, for example, the relationship of N (C0, Ca1, Cy) = [1-A (Ca1, Cy)] × [1-A (C0, Ca1)] × N (Cy) have.

N (C0, Ca1, Cy) = [1-A (Ca1, Cy)] × [1-A (C0, Ca1)] × N (Cy), the adjacency information A (r, s of FIG. 6 is satisfied ) And N (j) of FIG. 5, [1-A (Ca1, Cy)] × [1-A (C0, Ca1)] × N (Cy) for the second content is (1-0.54). X (1-0.64) x 75,732 = 12,541 are calculated, (1-0.47) x (1-0.64) x 132,563 = 25,293 for the third content, and (1-0.31) x (for the x content) 1-0.64) x 34,195 = 8,494 is calculated.

Therefore, the third content having the highest [1-A (Ca1, Cy)] × [1-A (C0, Ca1)] × N (Cy) is designated as the third home shopping content.

However, such a relationship in which N (C0, Ca1, Cy) = [1-A (Ca1, Cy)] × [1-A (C0, Ca1)] × N (Cy) is merely exemplary, and N (C0). , Ca1, Cy)) may be calculated using A (Ca1, Cy), A (C0, Ca1) and N (Cy) using other calculation methods.

Referring back to FIG. 7, the home shopping broadcast providing apparatus 100 ′ according to the second embodiment of the present invention may further include a transmitter 150 ′.

The transmitter 150 ′ may include a third transmission mode for transmitting all of the first home shopping content, the second home shopping content, and the third home shopping content to the first receiver 200-1 to the m-th receiver 200-m; And (i) if the P (i, C0) of the i-th receiver is greater than or equal to the threshold preference, transmit the first home shopping content to the i-th receiver, and (ii) P (i, C0) is less than the threshold preference and P (i, Ca1). ) Transmits the second home shopping content to the i-th receiver if the threshold preference is greater than or equal to (iii) P (i, C0) and P (i, Ca1) are less than the threshold preference and P (i, Ca2) is greater than or equal to the threshold preference. Transmit the third home shopping content to the i th receiver, and (iv) if the P (i, C0), P (i, Ca1) and P (i, Ca2) are all below the threshold preferences, send the first home shopping content to the i th receiver. One of the fourth transmission modes for transmission is performed. However, the product corresponding to the second home shopping content belongs to the Ca1 product group, and the product corresponding to the third home shopping content belongs to the Ca2 product group.

For example, the transmitter 150 ′ may transmit the multiplexed first home shopping content, the second home shopping content, and the third home shopping content to the first receiver 200-1 to the m th receiver 200-m through the home shopping channel. . Alternatively, the transmission unit 150 ′ transmits the first home shopping content, the second home shopping content, and the third home shopping content to the first receiver 200-1 to the m th receiver 200-m through a physical channel, respectively. The first receiver 200-1 to the m-th receiver 200-m may select a suitable one from among the first home shopping content, the second home shopping content, and the third home shopping content, and provide the same to the viewer.

<Modifications>

The first to fourth embodiments of the present invention described above are merely exemplary and may be variously modified.

For example, according to the first and third embodiments of the present invention, after the first home shopping content is designated, the content of which N (C0, Cy) is the maximum among the first to x-th content is the second home shopping content. Is specified. Thereafter, the home shopping broadcasting providing apparatus 100 transmits at least one of the first home shopping content and the second home shopping content to the first receiver 200-1 to the m-th receiver 200-m, respectively. Further, according to the second and fourth embodiments of the present invention, after the first home shopping content and the second home shopping content are designated, N (C0, Ca1 among content except for the second home shopping content among the first to xth contents are specified. , Cy) is designated as the third home shopping content. Thereafter, the home shopping broadcasting providing apparatus 100 transmits at least one of the first home shopping content, the second home shopping content, and the third home shopping content to the first receiver 200-1 to the m-th receiver 200-m, respectively. . However, these embodiments are merely exemplary, and the number of home shopping contents that the home shopping broadcasting providing apparatus 100 may provide to the first receiver 200-1 to the m th receiver 200-m is not limited thereto. .

For example, after the first home shopping content, the second home shopping content, and the third home shopping content are designated according to the second and fourth embodiments of the present invention, the second home shopping content and the third home shopping content among the first to x-th content are specified. The fourth home shopping content may be designated among the contents other than the content. The fourth home shopping content may be selected in a manner similar to that of designating the third home shopping content.

For example, overlapping with N (C0, Ca1, Ca2) in N (C0, Ca1, Cy) while changing y from 1 to x among contents other than the second home shopping content and the third home shopping content among the first to xth contents The y-th content having the maximum number N (C0, Ca1, Ca2, Cy) excluding the calculated receiver may be designated as the fourth home shopping content provided through the home shopping channel. However, the product corresponding to the third home shopping content belongs to the Ca2 product group. The home shopping broadcasting providing apparatus 100 may include a first home shopping content and a second home shopping content. At least one of the third home shopping content and the fourth home shopping content may be transmitted to the first receiver 200-1 to the m-th receiver 200-m, respectively.

Also, after the fourth home shopping content is designated, the fifth home shopping content may be designated in the same manner. The home shopping broadcasting providing apparatus 100 may include a first home shopping content and a second home shopping content. At least one of the third home shopping content, the fourth home shopping content, and the fifth home shopping content may be transmitted to the first receiver 200-1 to the m-th receiver 200-m through the home shopping channel, respectively.

Further, in the first and third embodiments, each of the first receiver 200-1 to the m -th receiver 200-m preferably includes preference information among the received first home shopping content and the second home shopping content. A higher value of may be selected and provided to the viewer.

For example, the first receiver 200-1 selects the second home shopping content if the value of the preference information of the second home shopping content is higher than the preference information of the first home shopping content in the first receiver 200-1. After the signal processing, it can be provided to the viewer.

Similarly, the m-th receiver 200-m selects the first home shopping content if the value of the preference information of the first home shopping content is higher than the preference information of the second home shopping content in the m-th receiver 200-m. After the signal processing, it can be provided to the viewer.

Similarly, in the second and fourth embodiments, each of the first receiver 200-1 to the m-th receiver 200-m preferably receives the first home shopping content. Among the second home shopping content and the third home shopping content, the highest value of the preference information may be selected and provided to the viewer.

In addition, the above-described first content to x-th content may be designated in advance according to the home shopping broadcasting policy or regulation of the home shopping operator. The home shopping broadcasting policy may include, for example, at least one of a price of a product, a selling date, an order method, and a broadcasting time zone. More specifically, only contents when a sale condition (eg, price) of a corresponding product is valid among the plurality of contents may be designated as the first content to the xth content. For example, if the home shopping broadcasting policy specifies that a product such as "adult underwear" is not broadcasted at 6 pm to 8 pm, the product corresponding to the adult underwear cannot be designated as the first content or the x content at that time. .

In addition, as described above, m may be any one of a total number of receivers that can receive and provide a home shopping channel and a predetermined number of receivers that can receive and provide a home shopping channel.

For example, if m is the total number of receivers that can receive and provide a home shopping channel, preference information may be more accurately calculated for each receiver. However, there is a disadvantage that the load for calculating the preference information also increases.

Thus, m may be, for example, the number of predetermined receivers among receivers that can receive and provide a home shopping channel. For example, m may be designated by dividing all receivers that can receive and provide a home shopping channel into a plurality of groups according to a predetermined criterion, and selecting a receiver that is a reference among each group. For example, m may be the number of the plurality of groups described above.

Although the configuration of the present invention has been described in detail based on embodiments and modifications, the above-described embodiments are merely illustrative of the present invention. Therefore, those skilled in the art will be able to further modify the above-described embodiments and modifications without departing from the essential characteristics of the present invention.
