Hereinafter, with reference to the drawings will be described the present invention in more detail.

1 is a block diagram provided to explain a content receiving apparatus according to an embodiment of the present invention.

Referring to FIG. 1, the content receiving apparatus 100 may include a remote controller 110, a set top box 120, a rendering device 130, a service provider 140, And a contents provider 150.

The remote controller 110 includes an operation unit 111 and a remote control signal transmitter 112, and the operation unit 111 includes a play button 111-1, a stop button 111-2, A rewind button 111-3, a fast forward button 111-4, and a pause button 111-5 are provided.

The set top box 120 may include a remote controller signal receiver 121, a contents usage score calculator 122, a contents receiver 123, a controller 124, a storage 125, and an interface unit ( 126).

However, other components that may be included in the content receiving apparatus 100 are excluded from the drawings and only those components necessary for describing the present invention will be illustrated.

The remote controller 110 generates one of a play signal, a pause signal, a stop signal, a fast forward signal, and a rewind signal. In other words, the user plays the play button 111-1, the end button 111-2, the rewind button 111-3, the fast forward button 111-4, and the pause button 111 provided on the operation unit 111. When one of the buttons is pressed by the operation of -5), a signal of the corresponding button is generated.

Here, the playback signal is a case where the user presses the play button 111-1 provided on the operation unit 111 to view the corresponding content from the beginning, or presses the play button 111-1 to view again from the point where it was previously paused. It is a signal generated in the case.

The pause signal is a signal generated when the user presses the pause button 111-5 provided on the operation unit 111 to temporarily stop playback of the corresponding content being viewed at a different position from the start position while watching the corresponding content.

The end signal is a signal generated when the user presses the end button 111-2 provided on the operation unit 111 to completely end the viewing of the content being played.

The fast-forward signal is a signal generated when the user presses the fast-forward button 111-4 provided on the operation unit 111 to move forward while skipping a portion of the corresponding content being played.

The rewind signal is a signal generated when the user presses the rewind button 111-3 provided on the operation unit 111 to rewind the corresponding content being played back and watch the part that has passed.

The generated signal is received by the remote control signal transmitter 112 and transmitted to the set-top box 120. That is, the remote control signal transmitter 112 transmits one of a play signal, a pause signal, an end signal, a fast forward signal, and a rewind signal received from the operation unit 111 to the remote control signal receiver 121 of the set-top box 120. do.

The set-top box 120 calculates an IPFR (Inclination, Percentage, Frequency, Recency) factor by using the playback signal, the pause signal, the end signal, the fast forward signal, and the rewind signal received from the remote control signal transmitter 112, Finally, the content usage score is calculated through the combination of the calculated IPFR factors. Detailed description thereof will be described later.

Here, the content use index refers to an index indicating the degree of satisfaction and interest of the user with respect to the corresponding content.

The remote control signal receiving unit 121 receives one of a playback signal, a pause signal, an end signal, a fast forward signal, and a rewind signal from the remote control signal transmitter 112.

The contents usage score calculator 122 uses the playback signal, the pause signal, the end signal, the fast forward signal, and the rewind signal received from the remote control signal receiver 121 under the control of the controller 124. Calculate the content use index.

Specifically, it is as follows.

The content usage score calculator 122 receives the play signal, the pause signal, the stop signal, the fast forward signal, and the like, which are received from the remote controller signal receiver 121. And an IPFR (Inclination, Percentage, Frequency, Recency) factor is calculated using the rewind signal.

Herein, the Inclusion factor is a function of the exposure and the selection rate.

Exposure refers to the user's viewing of general information such as the title or story of the content. Most users are interested when the content is exposed even though they have not seen the content. In other words, as the content is exposed, the interest of the user increases.

Selection refers to the user selecting and viewing general information about the corresponding content, and Selection Rate refers to a value obtained by dividing the number of selections made by the user by the value of the exposure. This means how many events among the exposed contents lead to selection, which means that the user who selects is more likely to watch the content later than the user who does not.

As such, the inclusion factor refers to a factor that indicates the tendency or interest of the user's content.

Percentage factor refers to a factor indicating the degree of viewing of the content. For example, when a user stops playing the content and watches another content while watching the content, the content does not satisfy the user's preference, and thus the viewing of the content is low. In the case of watching the entire contents from the beginning to the end or repeatedly watching a specific section, the content satisfies the user's preference and thus the degree of viewing of the contents is high.

The frequency factor is a factor indicating a case where the user selects to view the content again after a predetermined time after viewing the content. This means that the user remembers the content even though a certain amount of time has elapsed, indicating that the user's interest in the content is high.

Recency factor is a factor that indicates when the content is viewed. In other words, the more recently the user has viewed the content, the more frequently the user views the content, indicating that the user is more interested in the content.

Here, a method of using a play signal, a pause signal, a stop signal, a fast forward signal, and a rewind signal received from the remote control signal receiver 121 is as follows. same.

The play time, the pause signal, and the stop signal are used to calculate the time and section of the user's viewing of the content. Specifically, when the contents usage score calculator 122 receives a play signal from the remote controller signal receiver 121, the contents usage score calculator 122 calculates the content of the corresponding content. When the playback start point is detected and the contents usage score calculator 122 receives the pause signal or the stop signal from the remote control signal receiver 121, the contents usage score is displayed. The calculation unit 122 detects a playback end point of the corresponding content.

The contents usage score calculation unit 122 calculates the time and the period in which the user viewed the content by using the playback start point of the corresponding content and the playback end point of the corresponding content detected as described above. In addition, the larger the calculated time and interval, the higher the user's interest in the corresponding content, and as a result, a high Contents Usage Score is obtained.

The fast forward signal lowers the contents usage score. In other words, since the contents usage score calculator 122 receives the fast-forward signal from the remote control signal receiver 121, the content usage score calculator 122 skips a certain portion of the corresponding content and views the content usage score calculator 122. ) Calculates the content usage index by subtracting the fast forward section from the entire section where the content is viewed, and consequently lowers the content usage index. In other words, the playback count is zero in the fast forward section among the entire sections of the content. Detailed description thereof will be described later.

The rewind signal raises the Contents Usage Score. In other words, the content usage score calculator 122 receives the rewind signal from the remote control signal receiver 121 to rewind and re-view a portion of the corresponding content being viewed, so the content usage index calculator 122 In step 122, the content usage index is calculated by adding the rewind section in the entire section where the content is viewed, thereby increasing the content usage index. In other words, the number of playbacks is 2 for the section which has been rewound among all sections of the content. Detailed description thereof will be described later.

The method of calculating the contents usage score described above will be described in more detail using a mathematical equation as follows.

Here, uid is a user ID, eid is an episode (content) ID, and CUS [uid, eid] is a content use index of the content eid of the user uid. The total time of D [eid] content, i [uid, eid] is the order in which the user uid watched the content eid, and D _i [uid, eid] is the total viewing time in which the user uid used the content eid for the i th time. V [eid] refers to the validity period of the content, that is, the time at which the content eid can be viewed. T ₀ [uid, eid] is the time when the user uid first used the content eid, T _i [uid, eid] is the time when the user uid used the eid the content for the i th time, λ is the viewing frequency and the latest factor ( A coefficient representing the recency factor, which is determined through experimental data.

As can be seen from the above equation, D _i [uid, eid], which is the total viewing time when the user uid uses the i-th content eid, and T _i [uid, eid], when the user uid uses the i-th content eid for the i Must be stored. In order to reduce the amount of information to be stored, the above equation is simplified by expressing each Contents Usage Score as a previous value as follows.

Here, CUS _{N - 1} [uid, eid] is a Contents Usage Score expressed based on the N-1th viewing of the corresponding content.

In addition, Equation 1 can be expressed as follows.

Here, V [eid] represents the total time that the user can view the content eid, which includes a case where the user can potentially use the content.

T _i [uid, eid] -T ₀ [uid, eid] refers to the time until the user uid remembers the content eid and replays the content. The longer the time, the more frequently the user views the content. The content usage score will increase.

{T _i [uid, eid] -T ₀ [uid, eid]} / V [eid] represents the time until the user uid remembers the content eid and re-views in proportion to the total time that the content eid can be viewed. .

That is, the more frequently the user watches the corresponding content, the higher the value of the factors expressed in Equation 3, so that the content usage score is larger.

Equation 1 and Equation 3 described above and IPFR (Inclination, Percentage, Frequency, Recency) factors are described as follows.

In Equation 1 and Equation 3, a percentage factor representing a degree of viewing of a corresponding content is expressed as D _i [uid, eid]. The longer the D _i [uid, eid] period is, the larger the content of the content will be. As a result, the larger the value of CUS _P [uid, eid], the greater the value of CUS [uid, eid].

In Equation 1 and Equation 3, a frequency factor representing a case of selecting a content to be viewed again after a predetermined time elapses after viewing the content and a latest factor indicating a time of viewing the content Recency factor was expressed as CUS _FR [uid, eid]. In other words, as the user uid frequently watches the content eid, the value of CUS _FR [uid, eid] is increased, and as a result, the value of CUS [uid, eid] is also increased. In addition, as the user uid watches the content eid more recently, the value of T _i [uid, eid] is increased, and as a result, the value of CUS [uid, eid] is also increased.

Λ of Equations 1, 2, and 3 are coefficients representing frequency factor and latest factor and are determined through experimental data. That is, the experimentally calculated lambda is used to determine the ratio between CUS _P [uid, eid] and CUS _FR [uid, eid].

As described so far, the contents usage score calculation unit 122 is a play signal, a pause signal, a stop signal, and a fast forward signal received from the remote control signal receiver 121. The fast forward signal and the rewind signal are used to calculate the inclination factor, the percentage factor, the frequency factor, and the latest factor, and the calculated IPFR. Contents Usage Score is calculated using the (Inclination, Percentage, Frequency, Recency) factor and the above equations.

In the above, the process of calculating the contents usage score of the content in the video format or the content in the audio format has been described, but the method of calculating the contents usage score of the present invention is the usage index of the content in the text format. It is also applicable to the calculation.

For example, the scroll signal in the use of textual content corresponds to the play signal of video / audio format content, and the signal generated by stopping scrolling in the use of textual content is a video / audio signal. It corresponds to the pause signal of the format content, and the signal generated by the fast scrolling or moving to other parts of the text content is the fast forward or rewind signal of the video / audio format content. The signal generated by going to the beginning of the textual content or closing the text itself corresponds to the stop signal of the video / audio format content.

The contents usage score calculation unit 122 receives the signals generated by the remote control signal receiving unit 121 and receives the IPFR (Inclination, Percentage, Frequency, Recency) of the video / audio format content as described above. The IPFR factor of the content in the text format is calculated in the same manner as the factor calculation method, and the content usage score in the text format is calculated from the combination of the calculated IPFR factors.

Three examples of the calculation of the Contents Usage Score described so far are as follows. The following examples are cases in which λ is 1/4 and the usage period of the content eid is 30 days.

Example 1) When a user has watched all the content and then does not watch it again.

In this case, since D ₁ [uid, eid] = D [eid], T ₁ [uid, eid] = T ₀ [uid, eid], CUS [uid, eid] = 1. This value is an average value, and it does not exceed 1 because the user uid does not see the content eid frequently. In this case, the viewing time is the same as the showing time of the entire contents.

Example 2) When a user watches the entire contents once and then watches the same contents again after 15 days.

This case is as follows. D ₁ [uid, eid] = D ₂ [uid, eid] = D [eid], T ₁ [uid, eid] -T ₀ [uid, eid] = 0, {T ₂ [uid, eid] -T ₀ [uid, eid]} / V [eid] = 1/2. As can be seen from this equation, there are two singers. Two singers indicate that the viewing behavior of the user uid is twice. That is, the first value is 1. This means that the user uid continuously watches the content eid without stopping from the beginning to the end. The second value is 1.125. This finally results in CUS [uid, eid] = 2.215. As can be seen from the result, a value of Contents Usage Score is greater than 1, which indicates that the user is interested in the content.

Example 3) When a user plays a 120-minute content at 6:00 pm and watches it for 60 minutes from the beginning, the user pauses the content and returns to work after 40 minutes while doing other work. When you have fast forwarded a 30-minute segment and watched the remaining 30-minute segment to the end.

In this case, the section viewed by the user is two sections, which corresponds to 90 minutes out of 120 minutes in total. The calculation results in this case are summarized as follows.

Watch start time City hall end time Minutes watched Impact Index on CUS 18:00 19:00 60 0.50000 19:40 20:10 30 0.25015

This finally results in CUS [uid, eid] = 0.75015. As can be seen, when a fast forward signal is input, the overall contents usage score decreases.

As described above, the content usage score of specific content has been described so far, but the present invention provides a content usage score when various users watch various contents through an aggregation process. ) Can also be calculated. For example, four cases are as follows.

Example 1) Content usage index when a specific content is viewed by multiple users instead of one user (hereinafter referred to as Episode Contents Usage Score (ECUS)).

In this case, the content use index is calculated based on data obtained from all users or specific users who have viewed the content, and the following equation is used.

Here, ECUS [eid] is the content usage index of the content eid, U [eid] is the total number of users who watched the content eid, and CUS [j, eid] is the content usage index of the user j with respect to the content eid. As can be seen from Equation 4 above, this corresponds to an average value of the content use index values obtained from all users.

Example 2) Content usage index of all stations when the related contents are collected and grouped into one station (hereinafter referred to as Station Contents Usage Score (SCUS)).

In this case, the station content usage index is calculated based on the data obtained from each of the related contents, and the following equation is used.

Here, SCUS [sid] is the content usage index of the station sid, E [sid] is the total number of contents belonging to the station sid, and ECUS [e] is the content usage index of the content e. As can be seen from Equation 5 above, this corresponds to an average value of the content use index values obtained from the related contents.

Example 3) Content usage index for a specific user when a specific user watches a plurality of contents (hereinafter referred to as User Contents Usage Score (UCUS)).

In this case, the user content use index is calculated by clustering data obtained from the respective contents viewed by a specific user, and the following equation is used.

Where UCUS [uid] is the user content usage index for the user uid, E [uid] is the number of contents watched by the user uid, and CUS [uid, j] is the content usage index when the user uid watched the content j. . As can be seen in Equation 6 above, this corresponds to an average value of content use index values obtained from respective contents viewed by a specific user.

Example 4) Content usage index for a group of users (hereinafter referred to as Group Contents Usage Score (GCUS)). Demographic methods are used for this. That is, users are grouped by statistical criteria such as age, gender, education level, occupation, region, marital status, number of children, and the content usage index for this group is calculated. The following equation is used for this.

Here, GCUS [gid] is the content usage index of the group gid, U [gid] is the number of people of the group gid, and UCUS [u] is the content usage index of the user u. As shown in Equation 7 above, this corresponds to an average value of the content use index values for each of a specific group of users.

The clustered content use indexes described above are mainly used in the service provider 140 or the content provider 150.

Here, the content provider 150 refers to a device for dynamically providing content to the service provider 140 through a RSS (Really Simple Syndication) method.

Here, the RSS (Really Simple Syndication) method is a kind of rule made to easily distribute and subscribe to newly generated information on a website, and refers to a standard made to summarize, share, and exchange various contents.

The advantages of the RSS (Really Simple Syndication) method include the ability to select a channel that exactly matches the information desired by the user, to simultaneously access various channel sources, to record the history of various channels, to facilitate automated content linkage, and to structured XML data. Furnace conversion and processing is easy.

In addition, the content provider 150 may calculate its own content use index through a monitoring system (not shown). Through the content usage index calculated as described above, it is possible to provide content suitable for a user's preference.

The service provider 140 refers to a device that periodically provides the set-top box 120 with contents provided from the contents provider 150.

In addition, the service provider 140 may calculate its own content use index through a monitoring system (not shown) provided therein. Through the content usage index calculated as described above, it is possible to dynamically provide content suitable for a user's preference.

The content receiver 123 receives content from a service provider 140.

The interface unit 126 provides the content receiving index 123 and the content using index calculated by the content using index calculator 122 to the connected external rendering device 130.

The storage 125 stores the content usage index calculated by the content usage index calculator 122.

The rendering device 130 displays the content transmitted through the interface unit 126 and the content use index so that the user can view it. An example of a rendering device 130 is a digital television.

The controller 124 generally controls the content receiving apparatus 100. Specifically,

The controller 124 processes the play signal, the pause signal, the stop signal, the fast forward signal, and the rewind signal received by the remote controller signal receiver 121. The content usage index is transferred to the content usage index calculator 122, and the content usage index calculated by the content usage score calculator 122 is transferred to the storage 125. In addition, when the content receiving unit 123 receives the content from the service provider 140, the control unit 124 processes the content and renders the content through the interface unit 126 in a form that the user can view. Forward to 130.

2 is a flowchart provided to explain a method of calculating a content use index according to an embodiment of the present invention.

1 and 2, the remote controller signal receiver 121 receives a play signal from the remote controller signal transmitter 112 (S210).

In other words, when the user presses the Play button 111-1 provided on the operation unit 111 to view the corresponding content from the beginning, or the Play button to replay from the point where it was previously paused. The remote controller signal receiving unit 121 receives a play signal generated when the user presses 111-1. In operation S210, if the play signal is not received, the remote controller signal receiver 121 maintains the standby state until the play signal is received.

When the contents usage score calculation unit 122 receives a play signal from the remote control signal receiving unit 121, the relation index λ, the total length of the content eid (time), and the valid period of the content eid are detected. (S220).

As described above in Equation 1, the total length (time) of the content eid is represented by D [eid], and the validity period of the content eid is represented by V [eid].

When the first access of the content (S230), the content usage score calculation unit 122 sets the current time to the first time to use the content, and set the value of the content usage index to 0 storage unit In operation S240, it is stored in 125.

Subsequently, when the remote control signal receiving unit 121 receives the stop signal from the remote control signal transmitting unit 112, the contents usage score calculator 122 detects the playback end point.

In other words, when the user receives the end signal generated when the user presses the stop button 111-2 provided on the operation unit 111 to completely end the viewing of the content being played, the contents usage index Score) The calculation unit 122 detects a playback end point in the corresponding content at the time when the stop signal is received.

As such, the contents usage score calculator 122 calculates the contents usage score by using the first time of using the detected content in step S240 and the playback end point detected in the step S260. (S270).

The above process is summarized as follows.

When the content usage score calculator 122 receives a play signal from the remote control signal receiver 121, the content usage score calculator 122 determines a playback start point of the corresponding content. When the content usage score calculator 122 receives the pause signal or the stop signal from the remote control signal receiver 121, the content usage score calculator 122 detects the contents usage score calculator. 122 detects the playback end point of the content.

The contents usage score calculation unit 122 calculates the time and the period in which the user viewed the content by using the playback start point of the corresponding content and the playback end point of the content detected as described above, and finally, Calculate the contents usage score. It has been described above that Equation 1 or Equation 3 below is used to calculate the content use index.

Here, in step S230, when the access of the corresponding content is not the first time, the content usage score calculation unit 122 detects the pre-stored contents usage score and the time when the pre-stored contents are used for the first time. In operation S245, the remote controller signal receiving unit 121 detects a playback end point at the time when the stop signal is received, and calculates a contents usage score.

In addition, the final content is used by adding the previously used contents usage score to the contents usage score calculated using the playback start point of the content and the playback end point of the content in the above process. Calculate the Contents Usage Score

As such, when there is a pre-stored Contents Usage Score because the access of the corresponding content is not the first time, Equation 3 in which the previously stored Contents Usage Score is expressed rather than Equation 1 is used. It will be efficient to calculate the final Contents Usage Score for the content.

The control unit 124 stores the content usage score calculated in the two processes described above in the storage unit 125, and processes it in a form that can be viewed by the user, thereby rendering the rendering device through the interface unit 126. Transmit to 130 (S280).

3 is a diagram provided to explain a method of calculating a content use index according to an embodiment of the present invention.

1 to 3, as described above, when the user stops playing the content and watches another content while watching the content, the content does not satisfy the user's preference. When the viewing degree of the content is low, and the user watches the entire contents from the beginning to the end, or when the user watches the specific section repeatedly, the content satisfies the user's preference and thus the viewing degree of the contents is high.

The above process is divided into sections and described in more detail as follows.

The time t _{1 is a} time when the user presses the Play button 111-1 provided on the operation unit 111 to watch the corresponding content. As such, when a play signal is input to the remote controller signal receiving unit 121 at time t ₁ , the corresponding content is screened through the rendering device 130 under the control of the controller 124, and the contents usage index (Contents Usage) Score calculation unit 122 sets a time point t _{1 as} a playback start point of the corresponding content in order to calculate a contents usage score.

The time t _{3 is a} time when the user presses the rewind button 111-3 provided on the operation unit 111 to watch the content from the time t ₁ and watch again from the time t ₂ . That is, the T ₂₃ section is a section where the user repeatedly watches the corresponding content.

At the time t _4, the T ₂₃ section is repeatedly displayed and the user continues watching the content, and the fast forward button 111-4 provided on the operation unit 111 is skipped to skip a certain section of the content screening. It is time to press. That is, the section T _{45 is a} section in which the user does not watch the corresponding content.

t ₅ is a time control section 124 presses the fast-forward (Fast Forward), the user of the reproduction running and the command is provided to the operation unit 111 to re-view the content (Play) button 111-1 of the content It's time.

In addition, time t _{6 is a} time point when the user presses the stop button 111-2 provided on the operation unit 111 to end viewing of the corresponding content. As such, when a stop signal is input to the remote controller signal receiving unit 121 at time t ₆ , the corresponding content, which has been screened through the rendering device 130 under the control of the controller 124, is terminated, and the content usage index ( contents Usage Score) the calculation unit 122 sets the time t ₆ to the end point of the reproduction of the content.

As shown in the above process, the T ₁₂ section corresponds to the playback section, and the number of times the corresponding content plays on this section becomes 1, and the Contents Usage Score of the T ₁₂ section becomes 1, and the T ₂₃ section rewinds. The number of times the content of this section is played is 2, and the contents usage score of the T ₂₃ section is 2. And, the T ₃₄ section corresponds to the playback section, the number of playback of the corresponding content of this section is 1, the Contents Usage Score of the T ₃₄ section is 1, and the T ₄₅ section corresponds to the fast forward section. The number of times the content is played in this section is 0, and the contents usage score in the T ₄₅ section is 0. In addition, the T ₅₆ section corresponds to a playback section, and the number of times of playing the corresponding content of the section is 1, and the contents usage score of the T ₅₆ section is 1.

As described above, the present invention can calculate a contents usage score for each internal section of the corresponding content.

In addition, as seen in the above process, the fast forward signal lowers the contents usage score. In other words, the content usage score calculation unit 122 receives the fast forward signal from the remote control signal receiving unit 121 because the content usage score is to skip a certain portion of the corresponding content and watch the content usage index. The content usage score calculator 122 calculates a contents usage score by subtracting a fast forward section from all sections in which the corresponding content is viewed. As a result, the contents usage score is calculated. Will be lowered.

In addition, the rewind signal increases the contents usage score. In other words, since the contents usage score calculator 122 receives the rewind signal from the remote control signal receiver 121, the content usage score calculator 122 rewinds a portion of the corresponding content and re-views the contents usage score. Contents Usage Score calculation unit 122 calculates a Contents Usage Score by adding the rewind section in the entire section where the content is viewed, and consequently increases the Contents Usage Score. do.

That is, according to the present invention, the content usage index for the internal section of the corresponding content may also be calculated as described above together with the contents usage index for the corresponding content itself, so that the service providing apparatus 140 ) Or the content providing device 150 may determine which part of the corresponding content the user has focused on, and may direct future content provision based on the identified information.

4 is a flowchart provided to explain a method of calculating a content use index according to a received signal according to an embodiment of the present invention.

1 to 4, when the remote controller signal receiver 121 receives a play signal from the remote controller signal transmitter 112 (S410), the contents usage score calculator 122 corresponds to the corresponding content. The playback start point in the content is detected (S420).

In other words, as described above, when a Play signal is input to the remote controller signal receiving unit 121 at time t ₁ , the Contents Usage Score calculator 122 calculates the Contents Usage Score. In order to calculate, t ₁ is set as a playback start point of the corresponding content.

The detected playback start point is stored in the storage unit 125, and the corresponding content is played back from a position where a play signal in the corresponding content is input (S430). That is, the content is displayed from the position where the rendering device 130 receives the Play signal under the control of the controller 124.

If the remote control signal receiving unit 121 receives the stop signal from the remote control signal transmitting unit 112 while the corresponding content is being reproduced (S440), the contents usage score calculator 122 reproduces the content. The end point is detected (S450).

In other words, when the stop signal is inputted to the remote control signal receiver 121 at time t ₆ , the contents usage score calculator 122 calculates the contents usage score. To calculate, the time t ₆ is set as the playback end point of the content.

Using the playback start point detected in step S420 and the playback end point detected in step S450, the contents usage score calculator 122 calculates a contents usage score (S460).

Here, the calculated content usage index (CUS: Contents Usage Score) is the content usage index (CUS: Contents Usage Score) of the entire contents.

The control unit 124 stores the calculated total content use index in the storage unit 125 (S470).

Here, in step S440, if the remote control signal receiving unit 121 receives the rewind signal instead of receiving the stop signal from the remote control signal transmitting unit 112 while playing the corresponding content (S443), the content usage index ( Contents Usage Score) The calculating unit 122 detects a time point at which the rewind signal is received as the playback end point (S453).

In other words, as described above, when a rewind signal is input to the remote control signal receiving unit 121 at time t ₃ , the contents usage score calculator 122 calculates the contents usage score. In order to calculate, the time t ₃ is set as the content playback end point of the corresponding section. In other words, one playback section is provided from the time point t _{1 to the} time point t ₃ .

Using the playback start point detected in step S420 and the playback end point detected in step S453, the contents usage score calculator 122 calculates a contents usage score (S463).

Here, the calculated content usage index (CUS: Contents Usage Score) is a content usage index (CUS: Contents Usage Score) from time t _{1 to} time t ₃ .

The controller 124 stores the content usage index from the time t _{1 to the} time t ₃ in the storage 125 (S473).

The control unit 124 performs a rewind command from time t ₃ according to the received rewind signal (S483).

If the remote control signal receiving unit 121 receives the playback signal from the remote control signal transmitting unit 112 during the rewinding command, the remote control signal receiving unit 121 detects the reception time as the playback starting point (S493).

In other words, when a play signal is input to the remote control signal receiving unit 121 at the time t ₂ while the rewinding command is performed from the time t ₃ as described above, the contents usage score calculation unit 122 is performed. Sets the time point t _{2 as} the playback start point of the corresponding section.

Thereafter, a time point at which the end signal is input is detected as a play end point, and a content use index of the corresponding section is calculated. For example, t ₂ when the end signal is input to the time point t ₆ while trying to play back the content from the time, t ₂ calculates the usage index of the contents from time to time t _6. Further, when the end signal is input to the time point t _4, and t ₂ calculates the usage index of the content from the time t ₄ to time.

As can be seen from the above description, the total number of times of playback of the T ₂₃ section reproduced by rewinding is two, and the content usage index of the T ₂₃ section is two.

Here, while playing the corresponding content in step S440, the remote control signal receiving unit 121 receives a stop signal from the remote control signal transmitting unit 112, or instead of receiving a rewind signal in step S443, the fast forward ( When the fast forward signal is received (S445), the contents usage score calculation unit 122 detects the time when the fast forward signal is received as the playback end point (S455).

In other words, when the fast-forward signal is input to the remote control signal receiver 121 at time t ₄ as described above, the contents usage score calculator 122 calculates the contents usage score. T ₄ is set as the content playback end point of the corresponding section. That is, one playback section is provided from the time point t _{1 to the} time point t ₄ .

Using the playback start point detected in step S420 and the playback end point detected in step S455, the contents usage score calculator 122 calculates a contents usage score (S465).

Here, the calculated content usage index (CUS: Contents Usage Score) is a content usage index (CUS: Contents Usage Score) from time t _{1 to} time t ₄ .

The controller 124 stores the content use index from the time t _{1 to the} time t ₄ in the storage 125 (S475).

The control unit 124 performs a fast forward command from time t ₄ according to the received fast forward signal (S485).

If the remote control signal receiving unit 121 receives the playback signal from the remote control signal transmitter 112 while performing the fast forward command, it detects the time when the playback signal is received as the playback start point (S495).

In other words, as described above, when a play signal is input to the remote controller signal receiving unit 121 at a time t ₅ while performing a fast forward command from time t ₄ , the contents usage score calculation unit 122 is performed. ) Sets time t _{5 as} the playback start point of the corresponding section.

Thereafter, a time point at which the end signal is input is detected as a play end point, and a content use index of the corresponding section is calculated. For example, the t ₅ when the end signal is in the time t ₆ while trying to play back the content from the time input, t ₅ calculates the usage index of the content from the time t ₆ to time.

As can be seen from the above description, the total number of replays of the fast forward section T ₄₅ is zero, and the content usage index of the section T ₄₅ is zero.

Through the above process, the present invention, the content usage index (Contents Usage Score) for the content itself can be calculated with the content usage index (Contents Usage Score) for each internal section of the content.

As described above, according to the present invention, by calculating the content usage score of the content based on the analysis of the signal generated from the remote control, by the internal section of the content along with the content usage index for the content itself; It is possible to calculate the number of contents pages.

In addition, although the preferred embodiment of the present invention has been shown and described above, the present invention is not limited to the above-described specific embodiment, the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims Of course, various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.
