Description

  The present invention relates to a video viewing history acquisition apparatus, method, and program, and in particular, when viewing video on a personal computer (hereinafter referred to as a personal computer), video viewing for estimating a viewer's video preference. The present invention relates to a history acquisition apparatus, method, and program. More specifically, the present invention relates to a video viewing history acquisition apparatus, method, and program for acquiring a history of video viewed by an individual on a personal computer and calculating a degree of preference for video using history information.

In recent years, video sharing sites and video distribution sites have become widespread, and many videos have been provided. Therefore, attention has been focused on services for selecting and recommending videos that match the user's preferences from the vast videos provided on these sites. In order to provide such a service, a technique has been proposed in which a user's preference is learned from an operation performed on a video by a user and a time / number of times viewed. For example, there is a technique for estimating the user's preference using information (operations such as skip operation and time until skip operation) during a certain period of time when viewing a video (see Patent Document 1).
JP 2005-011307 A

  However, in the above-described conventional technology, the user's preference for video is calculated according to the viewing time (or the ratio of viewing time to the video length) and points given for various operations. is there.

  First, as a first problem, there is a problem that the viewing state is not reflected in the preference degree calculation and the selection / recommendation of the video. In the conventional technique, the preference level is calculated using the viewing time and the operation history. In other words, when viewing a video, it is implicitly assumed that only one video is being watched at the same time. The difference from the case of viewing while performing work cannot be reflected in the preference calculation. For example, if you are devoted to watching one video, it is considered that the preference is higher than if you were watching while doing other work. The degree of preference is the same.

  In addition, since video selection / recommendation is performed according to the above-described preference level, there is a problem in that video selection / recommendation reflecting a difference in preference due to a difference in the viewing state of the user cannot be performed. For example, the video that the user wants to watch at leisure is different from the video that the user wants to watch while working, but in the conventional technology, the same video is selected and recommended in all viewing states.

  Next, as a second problem, when the preference level is calculated using the video operation history, there is a problem that the viewing intention of the user who has performed the operation is not sufficiently drawn. In the technique of the above-mentioned patent document 1, when calculating the preference degree from the video operation history, negative evaluations are uniformly given to negative operations (fast forward, image size reduction, etc.) with respect to the interest in the video. It is done. For this reason, although the video itself is of interest, when viewing is performed while skipping because the video is long or has many redundant parts, the preference level is estimated to be lower than the actual level.

  The present invention has been made in view of the above points. Video viewing that enables calculation of a preference that reflects a user's viewing state and selection / recommendation of a video, and calculates a preference that more reflects the user's viewing intention. It is an object of the present invention to provide a history acquisition apparatus, method, and program.

In the present invention (claim 9), in the viewing style discrimination step (step 4),
The intention of the viewing behavior is determined based on the section length of the section where the normal reproduction of the video operation history is performed and the section length of the section where the reproduction is performed.

  The present invention (Claim 10) is a video viewing history acquisition program for causing a computer to function as each means constituting the video viewing history acquisition apparatus according to any one of Claims 1 to 4.

  As described above, according to the present invention, in addition to viewing time and video operation history, viewing style information, specifically, viewing behavior was mainly performed, viewing was performed in parallel with other work, etc. It is possible to acquire viewing intention information such as the viewing state and viewing the video evenly for grasping the contents, and reproducing the video one after another to determine the video to be viewed.

  By using the viewing style information described above, it is possible to calculate a preference level more in line with the user's intention than the preference level calculated using only the viewing time and the video operation history. For example, in the case where video viewing is the main action and when viewing is performed while other work is being performed, in the related art, the same preference is calculated when the viewing time and video operation are the same. On the other hand, by using the viewing state information that can be acquired according to the present invention, the preference of the former video can be calculated higher than the preference of the latter video.

  In the prior art, when viewing with a lot of skipping in order to grasp the contents, the number of skip operations is large and the viewing time is short, so the degree of preference is calculated low. However, by using the viewing intention information that can be acquired according to the present invention, it is possible to adjust the preference level to a value that matches the user's intention.

  In addition, by using viewing style information in video selection and recommendation, in addition to conventional support based on preference (for example, ranking by preference), you want to watch carefully while you are working or want to watch while working It is possible to provide support reflecting the viewing state (for example, narrowing down by viewing state).

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  In the following description, “reproduction” indicates a state (including fast forward and rewind states) in which sound / image of video data is output by the reproduction device. Also, “normal playback” refers to forward normal speed playback of playback. The “playback position” indicates a position on the currently played video data (elapsed time from the top of the video data).

[First Embodiment]
In the present embodiment, an example in which a user uses a personal computer to view a video stored in the personal computer is shown.

  FIG. 3 shows the configuration of the video viewing history acquisition apparatus according to the first embodiment of the present invention.

  The video viewing history acquisition apparatus shown in FIG. 1 includes an input / output unit 10, a video display screen information acquisition unit 20, a video operation history acquisition unit 30, a video information acquisition unit 40, a viewing style determination unit 50, a viewing style storage unit 60, and a storage. Section 70 and viewing history database 80.

  As shown in FIG. 4, the storage unit 70 includes, for each video ID, video display screen information (playback position, display position, display size), video operation history (operation time, operation content), video information (video length), A viewing style label (viewing state label, viewing intention label) is stored.

  The viewing history database (DB) 80 stores the display state determination result, the viewing style determination result, the degree of dedication, and the video information by the viewing style storage unit 60.

  Hereinafter, the process in said structure is demonstrated.

  FIG. 5 is a flowchart of video viewing history acquisition processing according to the first embodiment of the present invention.

  When the user starts viewing the video on the personal computer, the following processing is executed.

Step 10) Video ID acquisition step:
The input / output unit 10 acquires a video ID that is an ID for uniquely identifying a video that has been browsed. An example of the video ID is a file path, for example. The file path may be obtained from the window management information, or the user may manually specify the file path. In this step, the video ID is output to the video display screen information acquisition unit 20, the video operation history acquisition unit 30, and the video information acquisition unit 40.

Step 11) Image display screen information acquisition step:
Once this step is carried out, thereafter, it is periodically performed in one embodiment of the present invention at time intervals recorded in advance in the storage unit 70. When the video browsing is finished, the execution of the regular step is also finished. The video display screen information acquisition unit 20 receives the video ID, and uses the captured image of the display screen of the personal computer viewing the video or the window management information of the OS, and the personal computer viewing the video. In the display screen, the size and display position of the screen displaying the viewing video (video display screen) and whether the video display screen is hidden behind other screens or is visible to the user Are extracted together with the video ID to the viewing state discriminating unit 51 of the viewing style discriminating unit 50, and the process proceeds to step 141.

Step 12) Image operation history acquisition step:
Once this step is performed, the video operation history acquisition unit 30 acquires operations such as playback and fast-forwarding of the video while the video specified by the video ID acquired in step 10 is being browsed. And recorded in the storage unit 70. Each time an operation is detected, the operation may be sequentially stored in the storage unit 70, or information on the detected operation may be temporarily stored and periodically recorded in the storage unit 70 at predetermined time intervals. Also good. In the video ID acquisition step of step 10, when an operation indicating the end of browsing of the video specified by the video ID passed from the input / output unit 10 is detected, the video operation history acquisition in step 12 is ended, The video ID is output to the viewing style determination unit 50, and the process proceeds to step 14.

Step 13) Image information acquisition step:
In the video information acquisition unit 40, the video length of the video specified by the video ID passed from the input / output unit 10 is acquired and stored in the storage unit 70 in association with the video ID.

  The order in which the above steps 11, 12, and 13 are performed may be any order.

Step 14) Viewing style discrimination step:
Step 141) Viewing state determination step:
The viewing state discriminating unit 51 receives the discrimination result of the size, display position, and video state of the screen displaying the video ID and the viewing video (display screen during video), calculates the degree of viewing dedication, and based on this value Thus, the viewing state label to be given to the viewing image at the time when step 11 is performed is determined. The viewing state determination unit 51 outputs the determined viewing state label as an output to the viewing style storage unit 60 together with the video ID, and proceeds to step 143.

Step 142) Viewing intention determination step:
The viewing intention determination unit 52 receives the video ID as an input, and corresponds to the operation information corresponding to the video ID recorded in the storage unit 70 in step 12 and the video ID recorded in the storage unit 70 in step 13. The video length is acquired from the storage unit 70, the playback rate and skip rate are calculated, and the viewing intention label for the viewing video is determined based on these values. The viewing intention determination unit 52 passes the determined viewing intention label to the viewing style storage unit 60 and proceeds to step 143.

Step 143) Viewing style information storage step:
When the viewing style storage unit 60 receives the video ID and the viewing state label from the viewing state determination unit 51, the viewing style storage unit 60 stores them in the storage unit 70 in association with the video ID. When the video ID and the viewing intention label are received from the viewing intention determination unit 52, the video ID and the viewing intention label are recorded in the storage unit 70 in association with the video ID, and the process is terminated.

  Hereinafter, the viewing state determination step (step 141) in the viewing state determination unit 51 will be described in detail.

  FIG. 6 is a flowchart of the viewing state determination step in the first embodiment of the present invention. As shown in the figure, the processing includes a viewing dedication level calculation step and a viewing state label assignment step.

Step 1411) Dedication level calculation step:
The viewing state determination unit 51 calculates the degree of dedication of viewing behavior using the video display position and display size information acquired from the video display screen information acquisition unit 20 in step 11. This degree of dedication is calculated as a function that increases as the display position is closer to the center of the desktop image and as the display size is larger. The degree of dedication V is defined as the following formula, for example.

ここで、ｖ（ｘ，ｙ）はデスクトップ画像中の座標（ｘ，ｙ）で示される画素に与えられるポイントであり、中心に近いほど高いポイントとなる（例えば、中心からの距離）。また、Ｉはデスクトップ画像中の映像表示部分に含まれる画素の集合である。

Here, v (x, y) is a point given to a pixel indicated by coordinates (x, y) in the desktop image, and becomes a higher point as it is closer to the center (for example, a distance from the center). I is a set of pixels included in the video display portion in the desktop image.

Step 1412) Viewing state label giving step:
The viewing state determination unit 51 determines the viewing state using the video display position and display size information acquired from the video display screen information acquisition unit 20 in step 11. A flowchart of the determination method is shown in FIG. If the video is not displayed in the desktop image (step 101, No), it is labeled [not viewing] (step 102). When the video is displayed on the desktop, the display position includes a point at the center of the desktop, and the display size is equal to or larger than the threshold value (step 101, Yes, step 103, Yes), label it as [viewing main] ( Step 104), otherwise (Step 101, Yes, Step 103, No), label [view while] (Step 105).

  Specific examples to which each label is given are shown in FIGS.

  The example of FIG. 8 is a case where only one video is viewed near the center of the desktop. In this case, the video is displayed near the center of the desktop, and the screen size (120000 pixels) is equal to or greater than the threshold (60000 pixels), and thus is labeled [viewing main].

  The example of FIG. 9 is a case where a video is viewed while performing other work (for example, document creation). In this case, the screen size (60000 pixels) is equal to or larger than the threshold value (60000 pixels), but since the video display position is at the end (not including the center of the desktop), it is labeled as [view while].

  The example of FIG. 10 is a case where the next video (video 2) is played back without erasing the previously watched video (video 1) while continuously watching the video. . In this case, the video (video 2) reproduced later is labeled as [viewing main] because the entire video is displayed, and the video (video 1) that was viewed before is partially hidden. Therefore, it is labeled [Non-viewing].

  Note that the threshold is set by performing learning as learning data to which a correct answer label is assigned in advance. [Viewing main] is a case where only viewing behavior is being performed, [Watching while] is a case where other work is being performed in parallel with the viewing behavior, and [No viewing] is a video playback But not watched.

  Next, step 142 in FIG. 5 in the viewing intention determination unit 52 will be described in detail.

  FIG. 11 is a flowchart of the viewing intention determination step in the first embodiment of the present invention.

  The viewing intention determination unit 52 determines the viewing intention using the video operation history acquired by the video operation history acquisition unit 30 in step 12. This step includes a normal playback section / playback section calculation step, a playback rate / skip rate calculation step, and a viewing intention label assignment step.

Step 1421) Normal playback section / playback section calculation step:
The viewing intention determination unit 52 calculates a normal playback section length that is a total section length of a section that has been viewed by normal playback and a playback section length that is a total section length of a section that has been played back including fast-forwarding. .

  In the determination of a section, when there is normal playback and other playback states in the same section due to rewinding, the section is regarded as a normal playback section. FIG. 12 is a diagram for explaining a normal playback section and a playback section in the first embodiment of the present invention. In the example of the figure, normal reproduction from 0:00 to 1:00, fast-forwarding from 1:00 to 2:00, normal reproduction from 2:00 to 5:00, fast-forwarding from 5:00 to 7:00, 6: A case in which rewinding to 00 and normal reproduction to 9:00 is schematically shown. As shown in the figure, a section (0: 00 to 9:00) in a playback state including normal playback and fast forward is a playback section, and a section in which normal playback is performed once or more (0: 00 to 1: 00). 2:00 to 5:00, 6:00 to 9:00) are set as the normal playback section. From 6:00 to 7:00, fast-forward is performed for the first time, but normal playback is performed after rewinding.

Step 1422) Playback rate / skip rate calculation step:
The viewing intention determination unit 52 calculates the playback rate and skip rate defined by the following equations (1) and (2).

上記の再生率、スキップ率を算出する式は、上記に限られるわけではなく、式（１）で通常再生区間長の代わりに再生区間長を用いることも可能である。

The formulas for calculating the playback rate and skip rate are not limited to the above, and it is also possible to use the playback section length instead of the normal playback section length in Formula (1).

Step 1423) Viewing intention label assignment step:
The viewing intention determination unit 52 determines the viewing intention according to the values of the playback rate and skip rate. FIG. 13 is a flowchart of the viewing intent label assigning step in the first embodiment of the present invention.

  When the playback rate is equal to or higher than the threshold (step 201, Yes), [view] is assigned as the viewing intention label (step 202), and when the playback rate is lower than the threshold and the skip rate is lower than the threshold (step 201, No) , Step 203, No) is given [viewing interruption] as the viewing intention label (step 205), and the playback rate is smaller than the threshold and the skip rate is greater than or equal to the threshold (step 201, No, step 203, Yes). In the case of [1], a label [Skipping] is added (step 204).

  Specific examples to which each label is given are shown in FIGS.

  FIG. 14 shows viewing on the basis of normal reproduction, but viewing is performed while partially skipping redundant portions and the like. In this case, since the normal reproduction is basic, the reproduction rate is high and exceeds the threshold value. Therefore, it is leveled as [viewing].

  Next, FIG. 15 shows a case where the entire video is viewed little by little in order to grasp the contents of the entire video. In this case, since the number of normally reproduced parts is small, the reproduction rate is low and smaller than the threshold value, while the reproduction interval length is long and the skip rate is high. Therefore, it is labeled “Flying”.

  Finally, FIG. 16 shows a case where viewing of video is stopped halfway. Since the normal reproduction is basically performed until the stop is performed, the skip rate is low and smaller than the threshold value. In addition, since the playback is stopped at the beginning of the video, the playback rate is also low and smaller than the threshold value. Therefore, it is labeled [viewing interruption].

  The threshold is set by learning using learning data to which a correct answer label is assigned in advance. [Viewing] means watching for enjoying the video, [Interruption] is when the video is no longer interested and the video is stopped halfway, and [Take a look] is to grasp the subject of the video This is a case of viewing to a certain extent.

  Next, the processing of the viewing history storage step of step 143 in FIG. 5 in the viewing style storage unit 60 will be described.

  The viewing style storage unit 60 stores the determination result in the viewing state determination unit 51, the viewing style determination result in the viewing intention determination unit 52, and the degree of dedication in the viewing history database 80 together with video information.

  In this way, by storing the viewing style discrimination result in the database 80, in addition to the conventional video viewing support based on the degree of preference, the video that the user wants to watch carefully mainly as the main viewing, the video that the user wants to watch while working, etc. It is also possible to provide support through the viewing style axis of how you want to see the video.

  For example, a viewing state of [viewing main] [viewing while] can be used as a key for searching for a video that the user wants to view. Even if the user does not intentionally search, when the user is viewing the video, the viewing state can be determined in step 141 and a video matching the current viewing state can be recommended. .

[Second Embodiment]
In the present embodiment, a case will be described in which the preference level is calculated using information in the viewing history database 80 generated in the first embodiment.

  FIG. 17 is a flowchart of preference degree calculation according to the second embodiment of the present invention.

Step 301) Preference level calculating step:
In this step, the display state determination result, the viewing intention determination result, and the degree of dedication are read from the viewing history database 80, and the preference level is calculated by the preference level calculation technique as described in Patent Document 1 described above. .

Step 302) Preference level adjustment step:
In this step, the preference level calculated in step 301 is adjusted using the viewing style classification and dedication level values as shown by the following algorithm.

If Viewing status = [Not viewing]
P = 0
else
P = w ₀ P _o + w ₁ I _i + w ₂ V I = 0,1,2,
Note that P is the adjusted preference degree, P ₀ is the preference degree calculated in step 301, P _i is the evaluation score corresponding to the viewing intention determined in step 142, V is the degree of dedication calculated in step 1412, and w0 to w2. Is a weight at the time of addition and takes a positive value. Further, in I _i , the evaluation point I ₀ corresponding to [viewing], the preference level I ₁ for [skipping], and the preference level I ₂ for [viewing interruption] have a relationship represented by the following expression.

I ₀ > I ₁ > I ₂
[Other embodiments]
In the first embodiment described above, the case where the various units are in the same device has been described. However, even when the various units are in different devices, the present invention can be implemented by transmitting and receiving acquired data to each other. For example, FIG. 18 shows an apparatus configuration when viewing a video by streaming distribution.

  Information acquired by the video operation history acquisition unit 110 and the video display screen information acquisition unit 120 on the client 100 side is transmitted to the server 200 side. On the server 200 side, the transmitted information and video information acquisition unit 210 acquires the information. Using the information, the viewing style determination unit 220 determines the viewing style. Even when the various means are divided into three or more devices, it can be implemented by transmitting and receiving data generated by the various means.

  In this embodiment, the case where video is displayed on the screen of a personal computer has been described. However, the present invention can also be applied to a case where a plurality of programs are viewed simultaneously on a television.

  It is possible to construct the operation of the components of the apparatus shown in FIG. 3 as a program and install it in a computer used as a video viewing history acquisition apparatus, or distribute it via a network.

  Further, the constructed program can be stored in a portable storage medium such as a hard disk, a flexible disk, or a CD-ROM, and can be installed or distributed in a computer.

  The present invention is not limited to the above-described embodiment, and various modifications and applications can be made within the scope of the claims.
