Technical Field

The present invention relates to a hop-out rate measurement device for measuring a hop-out rate (round rate) of a broadcast service.

Background

With the development of communication technology and computing technology, broadcasting services are also rapidly developing. On the other hand, for the purpose of evaluating the efficiency of the broadcast service, the audience rating of the broadcast service is measured. For example, a broadcast service provider may use a rating as a reference for acquiring quality of broadcast service satisfaction such as a viewer watching a broadcast service, and an advertiser may use the rating as a reference for judging an advertisement effect when an advertisement is placed in the broadcast service.

The audience share is measured, for example, by collecting viewing behavior information on a broadcast service provided to a sample group after selecting the sample group evenly distributed by region, age, sex, and school calendar.

However, the conventional method of measuring the audience share is different from the actual audience share because the measurement is performed on a sample group. In addition, there is a disadvantage in that the rating of even a sample group cannot be accurately measured since a complicated manner is used for measuring the rating.

To solve such a problem, for example, korean patent No. 10-1751708 entitled "audience rating and advertisement effectiveness analysis method and system based on audience behavior recognition" filed by korea institute of electronic communications on year 2012, 8, 17 and granted on year 2017, 6, 22 discloses a technique for receiving an image of a viewer, generating viewer identification information based on the image, and then generating audience behavior information based on the viewer identification information, thereby more accurately measuring the audience rating of a sample group.

However, the method disclosed in the granted patent No. 10-1751708 also uses a complicated method such as pre-registering viewers for the purpose of measuring the rating as it is.

On the other hand, the pop-out rate generally refers to a rate at which a visitor of a website visits another page in the website or leaves the website without obtaining information. More specifically, for example, when a website has a start page and an underlying page linked to the start page, the pop-out rate refers to a rate at which a visitor leaves the website without visiting the underlying page although visiting the start page. A high hop rate means that the possibility that the visitor will bring about an action such as purchasing a product is low even if the visitor visits the web site, and a low hop rate means that the possibility that the visitor will bring about an action such as purchasing a product is high. Thus, the hop-out rate may be used, among other things, as a benchmark for evaluating websites of the internet.

However, the skip rate is a reference particularly applicable to internet services such as web pages, which has a disadvantage of being not applicable to broadcast services. That is, unlike web pages, broadcast services take the form of continuously providing content, so there is no starting page, and likewise, there is no underlying page. Therefore, the hop-out rate applicable to the internet service cannot be applied to the broadcast service as it is.

Disclosure of Invention

Technical problem

The present invention provides a skip rate measuring device for measuring a skip rate of a broadcast service by using service provision information generated based on a behavior of a viewer leaving from a channel after selecting the channel.

Technical scheme

In order to achieve the above technical object, the present invention provides a device for measuring a hop-out rate of a broadcast service, comprising: a first instruction to receive first to nth service provision information from first to nth receivers that receive and provide a broadcast service, respectively, the first to nth service provision information including at least details of one or more channels that are previously designated among first to mth channels that provide the broadcast service through the first to nth receivers, n being a natural number of 2 or more, m being a natural number of 2 or more; a second instruction for analyzing the first to nth service provision information, determining a first number of times based on a number of times for which the one or more channels are provided by the first to nth receivers for a time equal to or more than a first threshold during a predetermined period, and determining a second number of times based on a number of times for which the one or more channels are provided by the first to nth receivers for a time equal to or more than the first threshold and equal to or less than a second threshold during the predetermined period; and third instructions for extracting the one or more channel-related hop-out rate information based on the first number of times and the second number of times.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present invention, it is possible to provide a drop-out rate measuring apparatus that measures a drop-out rate of a broadcast service using service provision information generated based on a behavior of a viewer leaving from a channel after selecting the channel. For example, a specific channel related hop-out rate of the broadcast service may be measured, or a specific receiver related hop-out rate may be measured, or a specific content related hop-out rate provided by the broadcast service may be measured. In addition, it is possible to more efficiently evaluate the quality of a broadcast service or to acquire a viewer's interest based on the measured hop-out rate of the broadcast service.

Based on the measured hop-out rate according to the present invention, it is possible to extract additional information such as a reaction of the viewer, which cannot be acquired by means of the rating of the existing broadcasting service. Furthermore, based on the hop rate measured according to the present invention, it is also possible to extract the degree of interest for a particular channel, a particular content, or a viewer of a particular receiver. That is, a low hop-out rate means a high degree of interest, and a high hop-out rate means a low degree of interest. As such, the skip rate measured according to the present invention may be used as a reference for evaluating the quality of a broadcasting service or acquiring a viewer's interest, alone or in combination with an existing rating.

< first embodiment >

Fig. 1 is a block diagram showing an exemplary configuration of a trip-out rate measuring apparatus of the present invention.

Referring to fig. 1, the present invention provides a trip rate measurement apparatus 100 including one or more processors 110, one or more memories 130, and one or more programs 150 stored in the one or more memories 130 and executed by the one or more processors 110.

The one or more processors 110 read and execute the one or more programs 150 stored in the one or more memories 130. Although x (where x is a natural number) processors 110 are illustrated as one or more processors, for example, one or more processors may be provided. That is, the function of escape rate measuring apparatus 100 may be executed by one processor, or the function of escape rate measuring apparatus 100 may be executed by a plurality of processors in cooperation. For example, the function of the escape rate measuring apparatus 100 may be executed by executing an arithmetic function by a first processor and executing a communication function by a second processor.

One or more memories 130 store programs 150. The one or more memories 130 are storage media such as nonvolatile memories or volatile memories that can be stored and read, for example. Although one or more memories 130 are illustrated, a plurality of memories may be provided.

Although y (where y is a natural number) programs 150 are illustrated as one or more programs, for example, one or more programs may be provided. That is, the function of the slip-out rate measuring apparatus 100 may be realized by one program, or the function of the slip-out rate measuring apparatus 100 may be realized by cooperation of a plurality of programs. For example, the function of the escape rate measuring apparatus 100 may be realized by realizing the arithmetic function by the first program and realizing the communication function by the second program.

Hereinafter, the one or more processors 110, the one or more memories 130, and the one or more programs 150 are referred to as "processors 110", "memories 130", and "programs 150", respectively.

Fig. 2 is a diagram showing a system environment in which the inventive drop-out rate measuring apparatus is operated, and fig. 3 is a diagram exemplarily illustrating channel and schedule information of a broadcast service in the inventive drop-out rate measuring apparatus.

Referring to fig. 2, a system environment in which the apparatus for measuring a trip-out rate of the present invention operates includes the apparatus for measuring a trip-out rate 100 and first to nth receivers 200-1 to 200-n (where n is a natural number of 2 or more).

The hop-out rate measurement apparatus 100 is an apparatus for measuring the hop-out rate of a broadcast service. The hop-out rate measuring apparatus 100 may be, for example, a part of a broadcast service system that provides a broadcast service, but may be implemented independently of the broadcast service system. The hop-out rate measurement apparatus 100 may transmit and receive data by being connected to the first through nth receivers 200-1 through 200-n through a broadcast/communication network.

The first through nth receivers 200-1 through 200-n 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, which receive and provide digital broadcasting. In the specification of the present application, "digital broadcasting" refers to broadcasting services in the form of, for example, digital terrestrial broadcasting, digital cable broadcasting, digital satellite broadcasting, DMB broadcasting, IP-TV, OTT (Over the top, Over operator service), and VOD broadcasting. Preferably, the first receiver 200-1 to the nth receiver 200-n can perform bidirectional communication like an IP-TV, for example, and thus are configured to be able to transmit and receive data with the hop-out rate measurement apparatus 100.

n may be appropriately decided based on the number of receivers designated by the hop-out rate measurement apparatus 100 to measure the hop-out rate. For example, when the hop-out rate measurement apparatus 100 measures the hop-out rate associated with the entire receivers subscribed to the broadcast service system, n may be the number of the entire receivers subscribed to the broadcast service system. Further, for example, when the hop-out rate measurement apparatus 100 measures a hop-out rate associated with a particular group of receivers among receivers subscribed to the broadcast service system, n may be the number of receivers of the particular group. The specific group may be determined based on parameters such as region, performance of the receiver, charging system, and age of the subscriber, for example.

Referring to fig. 3, schedule information for first to mth channels (where m is a natural number of 2 or more) is exemplarily illustrated. The schedule information includes contents provided through the channel and a time when the contents are provided. m may be appropriately determined based on the number of channels designated by the hop-out rate measurement apparatus 100 to measure the hop-out rate. For example, when the hop-out rate measurement apparatus 100 measures a hop-out rate associated with an entire channel of the broadcast service, m may be the total number of channels of the broadcast service. Further, for example, when the hop-out rate measurement apparatus 100 measures a hop-out rate associated with a specific group of channels among the entire channels of the broadcast service, m may be the number of channels of the specific group.

Referring to fig. 3, the schedule information for the first channel 300-1 is configured to provide, for example, a first content, a first advertisement, a second content, a second advertisement, and a third content in order, the schedule information for the second channel 300-2 is configured to provide, for example, a fourth content, a third advertisement, a fifth content, a fourth advertisement, and a first content in order, and the schedule information for the m-th channel 300-m is configured to provide, for example, a sixth content, a fifth advertisement, a first content, a sixth advertisement, and a seventh content in order. As exemplarily illustrated in fig. 3, the schedule information for the first through mth channels 300-1 through 300-m may also each be configured to provide the first content. When the schedule information for the first through mth channels 300-1 through 300-m are configured to each provide the first content, the after-mentioned content-related skip rate information may be extracted.

In the specification of the present application, a "hop rate" is defined and used as a material for evaluating the quality of a broadcast service. In the specification of the present application, the jump rate is defined as follows.

a) Channel dependent drop out rate

The channel-dependent hop-out rate is calculated based on the specification of the ith channel (i is a natural number above 1 and below m) provided by the first through nth receivers 200-1 through 200-n for a particular channel of the first through mth channels 300-1 through 300-m:

[ formula 1]

The channel i associated hop-out rate (the number of times the channel i is provided by the first receiver 200-1 through the nth receiver 200-n for a pre-specified period of time for a time period above the first threshold and below the second threshold)/the total number of times the channel i is provided by the first receiver 200-1 through the nth receiver 200-n for a time period above the first threshold for a pre-specified period of time.

The predetermined period is a period for confirming the hop rate, for example, one day, one week, or one month.

The first critical value is a value determined in consideration of a delay time from signal processing to signal providing after receiving a user input selecting an i-th channel from the first receiver 200-1 to the n-th receiver 200-n. For example, the first receiver 200-1 may require a predetermined time until it receives a user input to select the i-th channel, for example, the 11 th channel, and then provides the channel by signal processing the 11 th channel. In addition, the viewer may change the channel by pressing the up button instead of the channel number in order to select a desired channel. The first threshold value is determined in consideration of such time. For example, the first critical value may be 3 seconds.

The second critical value is a value dynamically determined based on the identification information of the ith channel. Specifically, the second critical value is a value dynamically selected from a plurality of critical values based on the identification information of the ith channel, and may vary according to the characteristics of the channel or the characteristics of the content being broadcast in the channel. The second critical value may be differently set, for example, when the ith channel is a news channel, the second critical value is set to 10 seconds; when the ith channel is a movie channel, setting a second critical value as 20 seconds; when the ith channel is a home shopping channel, the second threshold value is set to 30 seconds. The second threshold means a time required for confirming contents and deciding whether to continue viewing or view the channel of the category when providing the contents after the viewer selects the ith channel. That is, the second threshold means a time required until the viewer selects whether to view the ith channel while excluding the zapping phenomenon (zapping).

Hereinafter, in the present specification, the ith channel-related hop-out rate is marked as follows:

BR (identification information of ith channel, start point of period, end point of period, first threshold, second threshold).

For example, BR (channel 11, 00 minutes and 00 seconds at 11/1/2017, 59 minutes and 59 seconds at 23/3 seconds, and 10 seconds at 11/30/2017) is the drop-out rate associated with channel 11, and represents the drop-out rate measured with the first threshold value set to 3 seconds and the second threshold value set to 10 during one month from 00 minutes and 00 seconds at 11/1/2017 to 59 minutes and 59 seconds at 23/30/2017 at 11/30.

b) Channel dependent hop-out rate for a receiver

The channel dependent hop-out rate of the receiver is calculated based on the specification of the specific channel, i.e., the ith channel (i is a natural number of 1 or more and m or less), among the first through nth receivers 200-1 through 200-n, provided by the specific receiver, i.e., the jth receiver (where j is a natural number of 1 or more and n or less) among the first through mth channels 300-1 through 300-m.

[ formula 2]

The i-th channel associated hop-out rate of the jth receiver (the number of times the ith channel is provided by the jth receiver for a predetermined period of time that is equal to or greater than the first threshold value and equal to or less than the second threshold value)/(the total number of times the ith channel is provided by the jth receiver for a predetermined period of time that is equal to or greater than the first threshold value).

Hereinafter, in this specification, the i-th channel-related hop-out rate of the j-th receiver is marked as follows:

BR (identification information of ith channel, identification information of jth receiver, start point of period, end point of period, first critical value, second critical value)

For example, BR (channel No. 11, identification information of the first receiver, 00 minutes 00 seconds at 1 st day 00 in 2017, 11 months at 30 th days 23 in 2017, 59 minutes 59 seconds, 3 seconds, 10 seconds) is the hop-out rate related to channel No. 11 of the first receiver 200-1, and indicates a hop-out rate measured by setting the first threshold value to 3 seconds and the second threshold value to 10 seconds in a month period from 00 minutes 00 seconds at 1 st day 00 in 2017 months at 11 months at 2017 to 59 minutes 59 seconds at 23 th day 23 in 2017 months at 11 months at 3 months in 2017.

c) Content dependent pop-out rate

The content-dependent skip rate is calculated based on the particulars of providing the specific content through the first through nth receivers 200-1 through 200-n.

[ formula 3]

Content-dependent hop rate (the number of times the content is provided by the first through nth receivers 200-1 through 200-n for a pre-specified period of time for a time above the first threshold and below the second threshold)/(the total number of times the content is provided by the first through nth receivers 200-1 through 200-n for a pre-specified period of time for a time above the first threshold).

On the other hand, preferably, the content-related skip rate may be calculated from a point of time when the viewer selects the content, for example, from a point of time when the viewer switches channels and selects the content. That is, in the specification of the present application, since the skip rate is measured with reference to, in particular, when the viewer switches channels, for example, when the viewer views the content in a state of not switching to a specific channel and broadcasts, for example, an advertisement or another content instead of the content at the time point of selecting the specific channel, the measurement of the skip rate may not be taken into account. For example, a content-dependent hop rate may be defined as shown in equation 4:

[ formula 4]

A content-dependent hop rate (the number of times the content is provided through the first channel 300-1 to the mth channel 300-m for the first receiver 200-1 to the nth receiver 200-n for a first critical value or more and for a time equal to or less than the second critical value from a time point of selecting the first channel 300-1 to the mth channel 300-m for the first receiver 200-1 to the nth receiver 200-n for a predetermined period)/(the total number of times the content is provided through the first channel 300-1 to the mth channel 300-m for the first critical value or more from a time point of selecting the first channel 300-1 to the mth channel 300-m for the first receiver 200-1 to the nth receiver 200-n for a predetermined period).

Hereinafter, the content and channel related skip rate in this specification is marked as follows:

BR (content identification information, period start point, period end point, first threshold value, second threshold value).

For example, BR (identification information of the first content, 00 minutes and 00 seconds at 11/1/2017/23/2017/59 minutes and 59 seconds at 23/2017/3 seconds, and 10 seconds) is a hop rate related to the first content, and indicates a hop rate measured by setting the first threshold value to 3 seconds and the second threshold value to 10 seconds in one month period from 00 minutes and 00 seconds at 11/1/2017/23/59 seconds at 11/30/2017/11/30.

d) Channel dependent pop-out rate for content

The channel-dependent drop-out rate of the content is calculated based on the particulars of the particular content provided by the first through nth receivers 200-1 through 200-n through a particular channel, e.g., the ith channel.

[ formula 5]

An ith channel-related hop-out rate of the content (the number of times the content is provided by the first receiver 200-1 to the nth receiver 200-n through the ith channel for a predetermined period of time for a time period greater than or equal to the first threshold value and less than or equal to the second threshold value)/(the total number of times the content is provided by the first receiver 200-1 to the nth receiver 200-n through the ith channel for a predetermined period of time for a time period greater than or equal to the first threshold value).

On the other hand, preferably, the channel-related skip rate of the content may be calculated from a point of time when the viewer switches to a specific channel and selects the content. That is, in the specification of the present application, since the skip rate is measured with reference to, in particular, when the viewer switches channels, for example, when the viewer views the content in a state of not switching to a specific channel and broadcasts, for example, an advertisement or another content instead of the content at the time point of selecting the specific channel, the measurement of the skip rate may not be taken into account. For example, a content-dependent hop rate may be defined as shown in equation 6:

[ formula 6]

The ith channel-related hop-out rate of the content ═ the number of times (the number of times the content is provided with the first critical value or more and the second critical value or less through the ith channel from the time point at which the ith channel is selected at the first receiver 200-1 to the nth receiver 200-n within a pre-specified period)/(the total number of times the content is provided with the first critical value or more through the ith channel from the time point at which the ith channel is selected at the first receiver 200-1 to the nth receiver 200-n within the pre-specified period).

Hereinafter, the ith channel-related drop-out rate of the content in this specification is marked as follows:

BR (identification information of content, identification information of ith channel, start point of period, end point of period, first critical value, second critical value).

For example, BR (identification information of the first content, identification information of the i-th channel, 00 minutes 00 seconds at 1 st day 00 in 2017, 00 minutes 00 seconds at 23 st day 23 in 2017, 11 th and 30 th months 23 in 2017, 3 seconds, and 10 seconds) is a skip rate related to the i-th channel of the first content, and indicates a skip rate measured by setting the first threshold value to 3 seconds and the second threshold value to 10 seconds in one month period from 00 minutes 00 seconds at 1 st day 00 in 2017 th month 1 to 59 minutes 59 seconds at 23 st day 23 in 2017 th month 30 in 2017.

e) Receiver dependent pop-out rate for content

The receiver-dependent skip rate of the content is calculated based on the specification of the specific content provided by a specific receiver among the first through nth receivers 200-1 through 200-n, that is, the jth receiver (where j is a natural number of 1 or more and n or less).

[ formula 7]

The content receiver-specific hop-out rate (the number of times the content is provided by the receiver j for a predetermined period of time that is equal to or greater than the first threshold value and equal to or less than the second threshold value)/(the total number of times the content is provided by the receiver j for a predetermined period of time that is equal to or greater than the first threshold value).

On the other hand, preferably, the channel-related skip rate of the content may be calculated from a point of time when the viewer switches to a specific channel and selects the content. That is, in the specification of the present application, since the skip rate is measured with reference to, in particular, when the viewer switches channels, for example, when the viewer views the content in a state of not switching to a specific channel and broadcasts, for example, an advertisement or another content instead of the content at the time point of selecting the specific channel, the measurement of the skip rate may not be taken into account. For example, a content-dependent hop rate may be defined as shown in equation 8:

[ formula 8]

A j-th receiver-related hop-out rate of the content ═ (the number of times the content is provided with the time greater than or equal to the first critical value and less than or equal to the second critical value through the first channel 300-1 to the m-th channel 300-m from the time point when the j-th receiver selects the first channel 300-1 to the m-th channel 300-m within a pre-specified period)/(the total number of times the content is provided with the time greater than or equal to the first critical value through the first channel 300-1 to the m-th channel 300-m from the time point when the first receiver 200-1 to the n-th receiver 200-n selects the first channel 300-1 to the m-th channel 300-m within the pre-specified period).

Hereinafter, the jth receiver-related hop-out rate as contained in this specification is labeled as follows:

BR (identification information of content, identification information of jth receiver, start point of period, end point of period, first critical value, second critical value).

For example, BR (first content, identification information of the first receiver, 00 minutes 00 seconds at 1/2017, 00 minutes 00 seconds at 23/59 minutes 59 seconds at 11/30/2017, 3 seconds, 10 seconds) is a hop rate relating to the first content of the first receiver 200-1, and indicates a hop rate measured by setting the first threshold value to 3 seconds and the second threshold value to 10 seconds during one month period from 00 minutes 00 seconds at 1/11/2017 to 59 minutes 59 seconds at 23/30/2017/11/30 in 2017.

In addition, in the present specification, BR (identification information of content, identification information of jth receiver, start point of period, end point of period, first critical value, second critical value) is also simply labeled as BR (identification information of content, identification information of jth receiver, first critical value, second critical value).

f) Receiver of content and channel dependent pop-out rate

The receiver of the content and the channel-dependent drop-out rate are calculated based on the specification that a specific receiver, i.e., a jth receiver (where j is a natural number of 1 or more and n or less) among the first through nth receivers 200-1 through 200-n provides specific content through a specific channel, i.e., an ith channel (i is a natural number of 1 or more and m or less) among the first through mth channels 300-1 through 300-m.

[ formula 9]

The hop-out rate of the content with respect to the jth receiver and the ith channel (the number of times the content is provided by the jth receiver through the ith channel for a predetermined period of time, the time being equal to or greater than the first threshold value and equal to or less than the second threshold value)/(the total number of times the content is provided by the jth receiver through the ith channel for the predetermined period of time, the time being equal to or greater than the first threshold value).

On the other hand, preferably, the channel-related skip rate of the content may be calculated from a point of time when the viewer switches to a specific channel and selects the content. That is, in the specification of the present application, since the skip rate is measured with reference to, in particular, when the viewer switches channels, for example, when the viewer views the content in a state of not switching to a specific channel and broadcasts, for example, an advertisement or another content instead of the content at the time point of selecting the specific channel, the measurement of the skip rate may not be taken into account. For example, a content-dependent hop rate may be defined as shown in equation 10:

[ formula 10]

The hop-out rate of the content with respect to the jth receiver and the ith channel (the number of times the content is provided with a time equal to or greater than the first threshold value and equal to or less than the second threshold value via the ith channel from the time point when the jth receiver selects the ith channel within a predetermined period)/(the total number of times the content is provided with a time equal to or greater than the first threshold value via the ith channel from the time point when the jth receiver selects the ith channel within the predetermined period).

Hereinafter, the j receiver and i channel related hop-out rate of the content in this specification are marked as follows:

BR (identification information of content, identification information of ith channel, identification information of jth receiver, start point of period, end point of period, first critical value, second critical value).

For example, BR (first content, channel No. 11, identification information of the first receiver, 00 hour/00 minute/00 second on day 1 11/month 1 in 2017, 59 minute/59 second on day 23/30 on month 11/month 30 in 2017, 3 seconds, 10 seconds) is a skip rate relating to the first content and channel No. 11 of the first receiver 200-1, and indicates a skip rate measured by setting the first threshold value to 3 seconds and the second threshold value to 10 seconds in a month period from 00 minute/00 second on day 1/month 11/month 30 on month 23/59 minute/second in 2017.

In addition, in the present specification, BR (identification information of content, identification information of ith channel, identification information of jth receiver, start point of period, end point of period, first critical value, second critical value) is also simply labeled as BR (identification information of content, identification information of ith channel, identification information of jth receiver, first critical value, second critical value).

Referring again to fig. 2, the apparatus 100 for measuring a hop-out rate may transmit, for example, the first threshold value and the second threshold value to the first receiver 200-1 to the nth receiver 200-n. In addition, the first through nth receivers 200-1 through 200-n may generate the first through nth service provision information based on the first and second threshold values and then transmit the first through nth service provision information to the hop-out rate measurement apparatus 100, respectively. Furthermore, the hop-out rate measurement apparatus 100 may further transmit, for example, identification information of the ith channel or identification information of the content to the first receiver 200-1 to the nth receiver 200-n. The first through nth receivers 200-1 through 200-n may generate first service provision information to nth service provision information based on identification information of an ith channel or identification information of content and a first critical value and a second critical value, and then transmit the first service provision information to the nth service provision information, respectively, to the drop-out rate measuring apparatus 100.

The structure of the jump-out rate measuring apparatus 100 according to the present invention will be described in more detail below.

Fig. 4 is an exemplary block diagram of a program stored and executed by the step of measuring the skip rate of the present invention.

Referring to FIG. 4, the program 150 includes first through third instructions 150-1 through 150-3. The program 150 may also include at least one of the fourth instruction 150-4 through the ninth instruction 150-9. The second instruction 150-2 may include a first sub-instruction 150-2-1 and a second sub-instruction 150-2-2. The fourth instruction 150-4 may include a third sub-instruction 150-4-1 and a fourth sub-instruction 150-4-2. The sixth instruction 150-6 may include a fifth sub-instruction 150-6-1 and a sixth sub-instruction 150-6-2. The eighth instruction 150-8 may include a seventh sub-instruction 150-8-1 and an eighth sub-instruction 150-8-2.

The first instruction 150-1 is configured to receive first service provision information through nth service provision information from a first receiver 200-1 through nth receiver 200-n, respectively, which receive and provide a broadcast service, the first service provision information through nth service provision information including at least details of one or more channels designated in advance among first channels 300-1 through mth channels 300-m, through which the broadcast service is provided by the first receiver 200-1 through nth receiver 200-n.

The one or more channels may be, for example, an ith channel (where i is a natural number of days of 1 or more and m or less) designated from among the first to mth channels. Alternatively, the one or more channels may be two or more channels designated among the first to m-th channels, for example.

The following description is based on a case where one or more channels are ith channels.

For example, the first instructions 150-1 receive a first service provision information from a first receiver 200-1 and an nth service provision information from an nth receiver 200-n.

The first to nth service providing information will be described in more detail with reference to fig. 5 to 8.

A procedure for generating service providing information based on at least a user input selecting channel No. 11 and a user input departing from channel No. 11 in a case where channel No. 11 is designated as channel i in the first receiver 200-1, for example, will be described with reference to fig. 5 to 8. Since another service provision information, for example, the nth service provision information can be generated in the nth receiver 200-n as in the first service provision information, a description of a process of generating the another service provision information will be omitted.

Fig. 5 is a diagram illustrating a process of selecting and leaving a channel at a receiver.

Referring to fig. 5, the first receiver 200-1 receives a user input by a viewer, for example, selecting channel number 11 via a remote controller, for example, at 15 minutes and 5 seconds at 7 am (S110). Thereafter, the first receiver 200-1 receives a user input by the viewer, for example, selecting channel number 9 via a remote controller, for example, at 15 minutes and 24 seconds at 7 am (S120). Thereafter, the first receiver 200-1 receives a user input by the viewer, for example, selecting channel No. 7 via a remote controller, for example, at 25 minutes and 17 seconds at 7 am (S130). Thereafter, the first receiver 200-1 receives a user input that the viewer selects channel number 11 again, for example, through a remote controller, for example, at 50 minutes 23 seconds at 7 am (S140). Thereafter, the first receiver 200-1 receives a user input that the viewer reselects channel No. 13, for example, through a remote controller, for example, at 50 minutes and 25 seconds at 7 am (S150). Thereafter, the first receiver 200-1 receives a user input that the viewer selects channel number 11 again, for example, through a remote controller, for example, at 5 minutes and 10 seconds at 8 am (S160). Thereafter, the first receiver 200-1 receives a user input by the viewer to turn off the power, for example, through a remote controller, for example, at 5 minutes and 30 seconds at 8 am (S170).

Fig. 6 to 8 are diagrams exemplarily illustrating service provision information generated according to the process illustrated in fig. 5.

Referring to fig. 6, first service provision information is exemplarily illustrated.

The first service providing information may include identification information of the first receiver 200-1 ("first receiver ID"), identification information of a channel, and a time when an event occurs through a remote controller. For example, as illustrated in fig. 6, the first service provision information may include "channel No. 11, 15 minutes and 5 seconds at 7 am", "channel No. 9, 15 minutes and 24 seconds at 7 am", "channel No. 7, 25 minutes and 17 seconds at 7 am", "channel No. 11, 50 minutes and 23 seconds at 7 am", "channel No. 13, 50 minutes and 25 seconds at 7 am", "channel No. 11, 5 minutes and 10 seconds at 8 am", and "off, 5 minutes and 30 seconds at 8 am".

Referring to fig. 6, the first receiver 200-1 is a means for generating first service provision information based on all user inputs for a change or departure of a channel and transmitting the first service provision information to the hop-out rate measurement apparatus 100 of the present invention. However, when the first service provision information is generated based on all user inputs for a change or a departure of a channel, the data size of the first service provision information may be large. Therefore, when the first service provision information is transmitted to the hop-out rate measurement apparatus 100, a communication load and a calculation load of the first receiver 200-1 may occur. In addition, there is a disadvantage that the measurement apparatus 100 performs calculation based on all user inputs for changing or leaving the channel.

Accordingly, the first service providing information can be simplified to include identification information of the first receiver 200-1, identification information of the ith channel, a time when the first receiver 200-1 receives a user input selecting the ith channel, and a time when the first receiver 200-1 receives a user input departing from the ith channel.

Referring to fig. 7, when channel No. 11 is designated as channel i, the first receiver 200-1 generates first service provision information based on a user input selecting channel No. 11 and a user input departing from channel No. 11. The user input for leaving channel No. 11 includes the input of the power button illustrated in step S170, i.e., the case of off.

Referring to fig. 7, the first service providing information may include identification information of the first receiver 200-1 ("first receiver ID"), identification information of the ith channel ("channel No. 11"), a time when the first receiver 200-1 receives a user input selecting the channel No. 11, and a time when the first receiver 200-1 receives a user input departing from the channel No. 11. For example, referring to fig. 7, the time when the user input selecting channel No. 11 is received and the time when the first receiver 200-1 receives the user input departing from channel No. 11 are illustrated as: "7 am 15 min 05 sec, 7 am 15 min 24 sec", "7 am 50 min 23 sec, 7 am 50 min 25 sec" and "8 am 5 min 10 sec, 8 am 5 min 30 sec".

On the other hand, referring to fig. 8, the first service providing information includes identification information of the first receiver 200-1 ("first receiver ID"), identification information of the ith channel ("channel No. 11"), a time when a user input selecting the channel No. 11 is received, and a difference between a time when a user input departing from the channel No. 11 is received by the first receiver 200-1 and a time when a user input selecting the channel No. 11 is received. For example, referring to fig. 8, the time and difference at which the user input selecting channel No. 11 is received is illustrated as "15 minutes 05 seconds at 7 am, 19 seconds", "50 minutes 23 seconds at 7 am, 2 seconds", and "5 minutes 10 seconds at 8 am, 20". The difference means the time, i.e., duration, at which channel number 11 is provided by the first receiver 200-1.

On the other hand, the first receiver 200-1 may also generate the first service provision information based on the first threshold value and the second threshold value.

For example, when the first critical value is 3 seconds, the first receiver 200-1 may generate the first service provision information only when the ith channel, for example, channel No. 11, is provided by the first receiver 200-1 for more than 3 seconds.

For example, in the first service provision information illustrated in fig. 8, "50 minutes 23 seconds at 7 am, 2 seconds" in the time and duration when the first receiver 200-1 receives the first user input is the ith channel, that is, the 11 th channel is provided by the first receiver 200-1 to be less than the first critical value. Therefore, when the first critical value is used, "50 minutes 23 seconds at 7 am, 2 seconds" may be excluded from the first service provision information.

Referring again to fig. 4, the second command 150-2 analyzes the first through nth service provision information received through the first command 150-1, and determines a first number of times based on the number of times the first through nth receivers 200-1 through 200-n provide the first through nth channels for a time greater than or equal to a first threshold value during a predetermined period, and determines a second number of times based on the number of times the first through nth receivers 200-1 through 200-n provide the first through nth channels for a time greater than or equal to the first threshold value and less than or equal to a second threshold value during the predetermined period.

The first frequency and the second frequency are values for extracting the hop rate information on one or more channels by the third command 150-3 described later.

The first number may be directly used, for example, the number of times the one or more channels are provided with the time above the first threshold value by the first through nth receivers 200-1 through 200-n within a pre-specified period. In addition, the second number may be directly used, for example, the number of times the one or more channels provide the time above the first threshold value and below the second threshold value through the first to nth receivers 200-1 to 200-n within a predetermined period.

On the other hand, when the first frequency and the second frequency are determined in order to extract one or more pieces of channel-related skip rate information, for example, i-th channel-related skip rate information, it is preferable to exclude a case where advertisement information is provided through the i-th channel. That is, this is because, when the advertisement information is provided, the viewer does not continue to view the channel and changes to another channel in most cases.

The second instruction 150-2 may include a first sub-instruction 150-2-1 and a second sub-instruction 150-2-2.

The first sub-instruction 150-2-1 determines the first frequency by excluding the frequency of the time for which the first threshold value or more is provided through the first receiver 200-1 to the n-th receiver 200-n for the one or more channels during the period in which the advertisement information is scheduled for the one or more channels in the pre-designated period from the frequency of the time for which the first threshold value or more is provided through the first receiver 200-1 to the n-th receiver 200-n for the one or more channels in the pre-designated period, and the one or more channels are determined by comparing the first service provision information to the n-th service provision information and the schedule information for the one or more channels.

For example, in fig. 6, if advertisement information is provided through the i-th channel, for example, in the case where channel 11 is provided for 2 seconds from 50 minutes 23 seconds at 7 am, the case where channel 11 is provided for 2 seconds from 50 minutes 23 seconds at 7 am does not account for the first count. For example, if the one or more channels include another channel in addition to the ith channel, the number of times of calculation is not counted in the case where the advertisement information is provided from the channel.

The second sub-instruction 150-2-2 may determine the second number by excluding the number of times when the one or more channels are provided with the first threshold value or more and the second threshold value or less through the first receiver 200-1 to the nth receiver 200-n during the period in which the one or more channels are provided with the advertisement information for the one or more channels during the pre-designated period from the number of times when the one or more channels are provided with the first threshold value or more and the second threshold value or less through the first receiver 200-1 to the nth receiver 200-n during the pre-designated period.

The first sub-command 150-2-1 and the second sub-command 150-2-2 can more accurately extract the above-mentioned one or more channel-related skip rate information, for example, the i-th channel-related skip rate information.

Referring again to fig. 4, the third instruction 150-3 extracts the aforementioned one or more channel-related hop-out rate information based on the first number and the second number determined by the second instruction 150-2. For example, if the one or more channels are the ith channel, the third instruction 150-3 extracts the information about the hop-out rate of the ith channel.

The information on the number of hops associated with more than one channel includes a ratio of the second number to the first number. The one or more channel-related hop-out rate information may further include at least one of the first number, information on a pre-specified period, and identification information of the one or more channels.

The reason why the first frequency is included in the skip rate information related to one or more channels is to extract the frequency of access to the one or more channels based on the number of times the viewer selects the one or more channels.

The reason why the one or more pieces of channel-related skip rate information include information on a period designated in advance and identification information on one or more channels is to identify the period and the target channel from which the one or more pieces of channel-related skip rate information are extracted when, for example, skip rate measuring apparatus 100 transmits the one or more pieces of channel-related skip rate information to another external apparatus.

For example, BR (channel identification information, period start point, period end point, first threshold value, second threshold value) may be extracted by the first through third instructions 150-1 through 150-3.

In addition, the desired channel-related skip rate information can be extracted for the desired threshold and the desired period by changing the first threshold, the second threshold, the start point of the period, the end point of the period, and the channel identification information.

The associated hop-out rate for the ith channel may be used, for example, as an indicator to assess loyalty to viewers of the ith channel. That is, even if the audience rating of the ith channel is low, if the skip-out rate is low, the ith channel may mean that the loyalty of the audience is high. Conversely, even if the audience rating of the ith channel is high, if the skip rate is high, the ith channel may mean that the loyalty of the audience is low.

Modes for carrying out the invention

< second embodiment >

The foregoing first embodiment has been explained based on the case where the hop-out rate information relating to the ith channel is extracted. That is, the description has been made based on an example in which the i-th channel-related hop-out rate information is extracted for the first receiver 200-1 to the n-th receiver 200-n as a whole.

However, the hop-out rate information related to the i-th channel may be extracted for each receiver.

Referring again to FIG. 4, the program 150 may also include a fourth instruction 150-4 and a fifth instruction 150-5.

The fourth instruction 150-4 analyzes the jth service provision information (where j is a natural number of 1 or more and n or less) from the first to nth service provision information, determines the third number based on the number of times the aforementioned one or more channels are provided with the first threshold value or more by the jth receiver from among the first to nth receivers 200-1 to 200-n within a predetermined period, and determines the fourth number based on the number of times the aforementioned one or more channels are provided with the first threshold value or more and the second threshold value or less by the first to nth receivers 200-1 to 200-n within the predetermined period.

The one or more channels may be, for example, an i-th channel (where i is a natural number of 1 or more and m or less) designated from among the first to m-th channels. Alternatively, the one or more channels may be two or more channels designated from the first channel to the m-th channel, for example.

The third frequency and the fourth frequency are values for extracting the hop rate information on one or more channels by the fifth instruction 150-5 described later.

The third number may directly use, for example, the number of times the aforementioned one or more channels are provided with the time above the first critical value by the jth receiver among the first through nth receivers 200-1 through 200-n within a pre-specified period. In addition, the fourth time may be directly used, for example, the number of times the one or more channels provide the time above the first threshold value and below the second threshold value through the first to nth receivers 200-1 to 200-n within a predetermined period.

However, as in the first embodiment, when the third frequency and the fourth frequency are determined in order to extract the information on the hop-out rate of the one or more channels of the jth receiver, it is preferable to exclude the case where the advertisement information is provided from the jth receiver through the ith channel. That is, this is because, when the advertisement information is provided, the viewer does not continue to view the channel and changes to another channel in most cases.

The fourth instruction 150-4 may include a third sub-instruction 150-4-1 and a fourth sub-instruction 150-4-2.

The third sub-instruction 150-4-1 determines the third frequency by excluding the frequency of the time of the.

The fourth sub-instruction 150-4-2 determines the fourth frequency by excluding the number of times the one or more channels are provided with the time equal to or more than the first threshold value and equal to or less than the second threshold value through the jth receiver during the period in which the advertisement information is scheduled for the one or more channels during the pre-designated period from the number of times the one or more channels are provided with the time equal to or more than the first threshold value and equal to or less than the second threshold value through the jth receiver during the pre-designated period.

Since the descriptions of the third sub-instruction 150-4-1 and the fourth sub-instruction 150-4-2 are substantially the same as the descriptions of the first sub-instruction 150-2-1 and the second sub-instruction 150-2-2, further description is omitted.

The third sub-instruction 150-4-1 and the fourth sub-instruction 150-4-2 can more accurately extract the aforementioned more than one channel-related skip rate information of the jth receiver, for example, the ith channel-related skip rate information of the jth receiver.

Referring again to fig. 4, the fifth instruction 150-5 extracts the aforementioned one or more channel-related hop-out rate information of the jth receiver based on the third and fourth times determined by the fourth instruction 150-4. For example, if the one or more channels are ith channels, the fifth instruction 150-5 extracts the hop-out rate information related to the ith channel of the jth receiver.

The aforementioned one or more channel-related hop-out rate information for the jth receiver comprises a ratio of the fourth number to the third number. The aforementioned one or more channel-related hop-out rate information of the jth receiver may further include at least one of a third number of times, information on a pre-specified period, identification information of the jth receiver, and identification information of the aforementioned one or more channels.

For example, BR (identification information of a channel, identification information of a receiver, a start point of a period, an end point of a period, a first critical value, a second critical value) may be extracted by the first instruction 150-1, the fourth instruction 150-4 to the fifth instruction 150-5.

Furthermore, the desired channel-related skip rate information of the desired receiver may be extracted for the desired threshold and the desired period by changing the first threshold, the second threshold, and the channel identification information, the receiver identification information, the period start point, the period end point, and the receiver identification information.

The i-th channel related hop-out rate of the jth receiver may be used, for example, as an indicator to assess loyalty to viewers of the jth receiver of the ith channel. That is, even if the audience rating of the ith channel is low, if the hop-out rate related to the ith channel of the jth receiver is low, it may mean that the loyalty of the audience of the jth receiver to the ith channel is high. Conversely, even if the audience rating of the ith channel is high, if the associated hop-out rate of the ith channel of the jth receiver is high, it may mean that the audience of the jth receiver has low loyalty to the ith channel.

< third embodiment >

The foregoing first embodiment has been explained based on the case where the hop-out rate information relating to the ith channel is extracted. That is, the description has been made based on an example in which the i-th channel-related hop-out rate information is extracted for the first receiver 200-1 to the n-th receiver 200-n as a whole.

However, the skip rate information when the specific contents are provided through the aforementioned one or more channels by the first through nth receivers 200-1 through 200-n may be extracted.

Referring again to FIG. 4, the program 150 may also include sixth instructions 150-6 and seventh instructions 150-7.

The sixth instruction 150-6 analyzes the schedule information and the first to nth service provision information for the one or more channels, determines a fifth number based on the number of times for which the content previously designated within a previously designated period is provided for the first threshold or more through the one or more channels and the first to nth receivers 200-1 to 200-n, and determines a sixth number based on the number of times for which the content is provided for the second threshold or more through the one or more channels and the first to nth receivers 200-1 to 200-n within the previously designated period.

The one or more channels may be, for example, an i-th channel (where i is a natural number of 1 or more and m or less) designated from among the first to m-th channels. Alternatively, the one or more channels may be two or more channels designated from the first channel to the m-th channel, for example.

The seventh instruction 150-7 extracts the channel-related skip rate information of the one or more channels of the content based on the fifth and sixth times extracted by the sixth instruction 150-6. For example, if the at least one channel is the ith channel, the seventh instruction 150-7 extracts the corresponding skip rate information of the ith channel of the content.

The aforementioned one or more channel-related skip rate information of the content includes a ratio of the sixth number to the fifth number. The aforementioned one or more channel-related skip rate information of the content may further include at least one of a fifth number of times, information on a pre-specified period, identification information of the content, and identification information of the aforementioned one or more channels.

On the other hand, preferably, the aforementioned one or more channel-related skip rate information of the content may be calculated from a point of time when the viewer switches to a specific channel and selects the content.

That is, in the specification of the present application, since the skip rate is measured with reference to, in particular, when the viewer switches channels, for example, when the viewer views the content in a state of not switching to a specific channel and broadcasts, for example, an advertisement or another content instead of the content at the time point of selecting the specific channel, the measurement of the skip rate may not be taken into account.

The sixth instruction 150-6 may include a fifth sub-instruction 150-6-1 and a sixth sub-instruction 150-6-2.

The fifth sub-instruction 150-6-1 determines the fifth number based on the number of times that the content previously designated through the one or more channels provides the time greater than or equal to the first critical value from the time point when the one or more channels are selected at the first receiver 200-1 through the nth receiver 200-n within the previously designated period.

The sixth sub-instruction 150-6-2 determines the sixth number based on the number of times that the content previously designated through the one or more channels provides the time above the first critical value and below the second critical value from the time point when the one or more channels are selected at the first receiver 200-1 through the nth receiver 200-n within the previously designated period.

This enables more accurate calculation of the out-rate information on the one or more channels of the content.

For example, BR (identification information of contents, period start point, period end point, first threshold value, second threshold value) may be extracted by the first instruction 150-1, the sixth instruction 150-6 to the seventh instruction 150-7. That is, when more than one channel includes the first channel 300-1 to the mth channel 300-m at the same time, BR (identification information of contents, period start point, period end point, first threshold value, second threshold value) may be extracted by the first instruction 150-1, the sixth instruction 150-6 to the seventh instruction 150-7.

For example, BR (identification information of contents, identification information of channels, start point of period, end point of period, first critical value, second critical value) may be extracted by the first instruction 150-1, the sixth instruction 150-6 to the seventh instruction 150-7. That is, if one or more channels are, for example, the ith channel, BR (identification information of content, identification information of the ith channel, start point of period, end point of period, first threshold value, second threshold value) can be extracted by the first command 150-1, the sixth command 150-6 to the seventh command 150-7.

In addition, the desired channel-related skip rate information of the desired content may be extracted for the desired threshold and the desired period by changing the first threshold, the second threshold, the identification information of the content, the identification information of the channel, the start point of the period, and the end point of the period.

The associated hop-out rate for the ith channel of the content may be used, for example, as an indicator to assess loyalty to viewers of the ith channel of the content. That is, even if the audience rating of the ith channel is low, if the jumping-out rate related to the ith channel of the content is low, it may mean that the loyalty of the audience of the ith channel to the content is high. Conversely, even if the audience rating of the ith channel is high, if the associated drop-out rate of the ith channel of the content is high, it may mean that the audience of the ith channel has low loyalty to the content.

< fourth embodiment >

The third embodiment has been described based on the case where the above-described one or more pieces of channel-related skip rate information of the specific content are extracted. That is, an example in which specific content is provided through the aforementioned one or more channels by the first through nth receivers 200-1 through 200-n is explained.

However, the skip rate information when a specific receiver, for example, the jth receiver, among the first through nth receivers 200-1 through 200-n provides a specific content through the aforementioned one or more channels may be extracted.

Referring again to FIG. 4, the program 150 may also include eighth instructions 150-8 and ninth instructions 150-9.

The eighth instruction 150-8 analyzes the jth service provision information from among the first service provision information to the nth service provision information, determines the seventh number based on the number of times the content previously designated within the previously designated period is provided by the jth receiver from among the first receiver 200-1 to the nth receiver 200-n for the time equal to or more than the first threshold value through the one or more channels, and determines the eighth number based on the number of times the content is provided by the jth receiver within the previously designated period for the time equal to or more than the first threshold value and equal to or less than the second threshold value through the one or more channels.

The ninth command 150-9 extracts the hop-out rate information on the jth receiver of the content and the one or more channels based on the seventh frequency and the eighth frequency determined by the eighth command 150-8. For example, if the at least one channel is the ith channel, the ninth command 150-9 extracts the skip rate information related to the jth receiver and the ith channel of the content.

The hop-out rate information associated with the jth receiver of the content and the one or more channels includes a ratio of the eighth number of times to the seventh number of times. The information on the number of times of the skip of the receiver j of the content and the one or more channels may further include at least one of information on a period designated in advance, identification information of the content, identification information of the receiver j, and identification information of the one or more channels.

On the other hand, it is preferable that the skip rate information on the jth receiver of the content and the one or more channels is calculated from a time point when the viewer switches to the one or more channels in the jth receiver and selects the content. That is, in the specification of the present application, since the skip rate is measured with reference to, in particular, when the viewer switches channels, for example, when the viewer views the content in a state of not switching to a specific channel and broadcasts, for example, an advertisement or another content instead of the content at the time point of selecting the specific channel, the measurement of the skip rate may not be taken into account.

The eighth instruction 150-8 may include a seventh sub-instruction 150-8-1 and an eighth sub-instruction 150-8-2.

The seventh sub-instruction 150-8-1 determines the seventh number based on the number of times the previously designated content is provided for the time equal to or more than the first threshold value through the one or more channels from the time point when the jth receiver among the first through nth receivers 200-1 through 200-n selects the one or more channels within the previously designated period.

The eighth sub-instruction 150-8-2 determines the eighth number based on the number of times the content previously designated through the one or more channels provides a time equal to or more than the first threshold value and equal to or less than the second threshold value from the time point when the j-th receiver selects the one or more channels within a previously designated period.

This makes it possible to more accurately calculate the hop-out rate information on the jth receiver of the content and the one or more channels.

For example, BR (identification information of content, identification information of jth receiver, start point of period, end point of period, first critical value, second critical value) may be extracted by the first instruction 150-1, the eighth instruction 150-8 to the ninth instruction 150-9. That is, when more than one channel includes the first channel 300-1 to the mth channel 300-m at the same time, BR (identification information of contents, identification information of the jth receiver, a period start point, a period end point, a first critical value, a second critical value) may be extracted by the first instruction 150-1, the eighth instruction 150-8 to the ninth instruction 150-9.

For example, BR (identification information of content, identification information of ith channel, identification information of jth receiver, start point of period, end point of period, first critical value, second critical value) may be extracted by the first instruction 150-1, the eighth instruction 150-8 to the ninth instruction 150-9. That is, if one or more channels are, for example, the ith channel, BR (identification information of content, identification information of the ith channel, identification information of the jth receiver, start point of period, end point of period, first threshold value, second threshold value) can be extracted by the first command 150-1, the eighth command 150-8 to the ninth command 150-9.

Further, the first threshold, the second threshold, the identification information of the content, the identification information of the channel, the identification information of the receiver, the start point and the end point of the period may be changed to extract the desired receiver of the desired content and the desired channel-related skip rate information for the desired threshold and the desired period.

The hop-out rate associated with the jth receiver and ith channel of the content may be used, for example, as an indicator for assessing loyalty to viewers of the ith channel of the content in the jth receiver. That is, even if the audience rating of the ith channel is low, if the drop-out rate of the jth receiver of the content and the ith channel is low, it may mean that the loyalty of the audience of the ith channel in the jth receiver to the content is high. Conversely, even if the audience rating of the ith channel is high, if the j-th receiver of the content and the associated skip-out rate of the ith channel are high, the loyalty of the audience of the ith channel in the j-th receiver to the content is low.

As described above, according to the present invention, it is possible to provide a drop-out rate measuring apparatus that measures a drop-out rate of a broadcast service using service provision information generated based on a behavior of a viewer leaving from a channel after selecting the channel. For example, a specific channel related hop-out rate of the broadcast service may be measured, or a specific receiver related hop-out rate may be measured, or a specific content related hop-out rate provided by the broadcast service may be measured. In addition, it is possible to more efficiently evaluate the quality of a broadcast service or to acquire a viewer's interest based on the measured hop-out rate of the broadcast service.

Based on the measured hop-out rate according to the present invention, it is possible to extract additional information such as a reaction of the viewer, which cannot be acquired by means of the rating of the existing broadcasting service. Furthermore, based on the hop rate measured according to the present invention, it is also possible to extract the degree of interest for a particular channel, a particular content, or a viewer of a particular receiver. That is, a low hop-out rate means a high degree of interest, and a high hop-out rate means a low degree of interest. As such, the skip rate measured according to the present invention may be used as a reference for evaluating the quality of a broadcasting service or acquiring a viewer's interest, alone or in combination with an existing rating.

Although the structure of the present invention has been described in detail, it is merely an exemplary description of the present invention and those skilled in the art to which the present invention pertains may implement various modifications within the scope not departing from the essential characteristics of the present invention.

Therefore, the embodiments disclosed in the present specification are intended to illustrate rather than to limit the invention, and the spirit and scope of the invention is not limited to such embodiments. The scope of the invention should be construed by the claims that follow, and all techniques that come within the range of equivalents thereof should be construed as being within the scope of the claims.
