A viewing analysis system according to an embodiment of the present invention will be described below. The viewing analysis system of this embodiment attempts to analyze the viewing status of moving images.

FIG. 1 is a diagram showing an example of a screen 1 showing the structure of a moving image output in the viewing analysis system of this embodiment. In the viewing analysis system of the present embodiment, a plurality of moving images are distributed, and the moving image to be reproduced after a certain moving image is determined by, for example, selecting options displayed on the screen of the moving image. A video to be played next is specified in advance in association with conditions such as which option is selected. Therefore, a tree structure is formed by a plurality of moving images. By reproducing the video corresponding to the root of the tree structure, following the link according to the conditions, and reproducing the video related to the next node, the story as a whole can be branched. On the display screen 1 shown in FIG. 1, such a structure of a branching story with a plurality of moving images can be displayed. For example, from the moving image 11, which is the root node of the tree structure, it is possible to branch to two moving images 12 and 13 according to conditions.

FIG. 2 is a diagram showing an example of the screen 4 showing the viewing status of the moving image output in the viewing analysis system of this embodiment. In the viewing analysis system of the present embodiment, for each video in a tree-structured video group in which the story branches, and for each layer of the tree structure, statistical values related to video viewing are displayed, so that in the entire branching story It allows you to understand how viewers browsed. Statistical values related to viewing include, for example, the total number of views, the total number of interactions (a viewer taking some action on the screen, such as a click, and inputting data into the system), the total number of exits, and the length of stay. The average value of (movie viewing time) may be included. These statistical values can be calculated in units of a predetermined period (for example, any period such as one month or three months can be set).

Here, the withdrawal of the viewer means that the viewer stopped watching the video. A typical example of viewer leaving is when the viewer closes the screen or window on which the video was being viewed, but when the video moves off the screen by scrolling the screen on which the video was being viewed. Or, if you start watching a different content such as another video or web page on the screen where you were watching a video, move from the time point of the video you were watching to another point (rewind and fast forward) will also be measured as leaving the viewed video.

In the example of FIG. 2, statistical information 21 is displayed for a moving image 21 related to the root of the tree structure, with the number of views being 5,000, the number of interactions (clicks) being 3,500, the number of withdrawals being 1,500, and the average length of stay being 01:24. ing. Similarly, for videos 12 and 13 branching from video 11, statistical information 22 and 23 are displayed for videos 12 and 13, respectively.

Furthermore, screen 4 also displays statistical information for each layer of the tree structure. For example, in the example of FIG. 2, the statistical information 24 about the first layer is displayed, and since the first layer is only the root, the same result as the statistical information 21 about the video 11 is displayed. . In addition, since the second layer can be branched into the two moving images 12 and 13, the statistical information 25 obtained by summarizing the viewing information of the moving images 12 and 13 is displayed.

FIG. 5 is a diagram showing a software configuration example of the analysis server 2. As shown in FIG. As shown in FIG. 4 , the analysis server 2 can include a video storage unit 231 , a viewing information storage unit 232 , a tag storage unit 233 , a video distribution unit 211 and a behavior analysis unit 213 .

The moving image storage unit 231 stores information on moving images to be distributed to viewers (hereinafter referred to as moving image information). For example, the moving image storage unit 231 can store moving image data in association with a moving image ID that identifies the moving image. The moving image data can be data recorded in a format such as MPEG, for example.

The viewing information storage unit 232 stores information (hereinafter referred to as viewing information) indicating behavior of viewers related to videos viewed for each viewer. The viewing information includes a viewer ID indicating the viewer who viewed the moving image, a moving image ID indicating the moving image, a point in time, and an action taken by the viewer at the point in time.

Actions taken by the viewer while viewing the video may include, for example, starting playback of the video (video playback), sending a comment, and the like. Also, in the present embodiment, the behaviors included in the viewing information may include the following withdrawals. In this embodiment, the following withdrawals are distinguished as (1) to (4) as positive withdrawals and (5) as negative withdrawals. It should be noted that, for example, (1) can be arbitrarily set as positive, negative, or neither (neutral) for each type of withdrawal, such as a negative evaluation.

(1) "external transition"
Indicates screen transition to content other than the video being viewed.
In the present embodiment, even among external transitions, the action that triggered the transition of the screen to the external content is distinguished and acquired. For example, the following categories of behavior may be included:
"Tag/end screen image click (direct external link)"
Indicates that the transition to the outside was made by clicking the tag in the image or the end screen of the video.
"Button click in popup"
Indicates that a button in a pop-up screen displayed while watching a video was clicked.
"Click external link in coupon"
Indicates that an external link set in a coupon provided while watching a video was clicked.

(2) "Story branch"
Indicates a transition to a subsequent video that connects to the video being viewed. For example, when a video contains multiple options and a video corresponding to the selection of the options is played back, it indicates that the video has transitioned to the subsequent video.
In the present embodiment, even among the story branches, the behavior that triggered the branching is to be acquired separately. For example, the following categories of behavior may be included:
"Click tag/end screen image (select story)"
Indicates that the transition to the next video was made by clicking the tag in the image or the end screen of the video.
"Clicking a submit button on a regular form with story selection"
A form containing options for branching the story is displayed on the display screen of the moving image, and the transmission of the form indicates transition to the subsequent moving image.
"Click Choice in Story Choice Only Form"
A dedicated form for selecting options for story branching is displayed on the display screen of the moving image, and the transmission of the form indicates transition to the subsequent moving image.
"Form link button click when form submission is complete"
A form for data input is displayed on the display screen of the moving image, and after the form is sent, the link to the subsequent moving image is clicked to indicate that the transition to the subsequent moving image has been performed.
"Story HOME button click"
It indicates that the transition of the moving image is made by clicking the button (HOME button) for returning to the beginning of the story on the moving image display screen.
"Story PREV button click"
Indicates that the transition of the video was made by clicking the button (PREV button) for returning to the previous video in the story development of the video.

(3) Transition within moving image Indicates that rewinding or fast-forwarding of the viewed moving image has been performed.
In the present embodiment, it is assumed that, even among intra-moving-image transitions, the behavior that triggered the transition is distinguished and acquired. For example, the following categories of behavior may be included:
"Click the tag/end screen image (link in the video)"
Indicates rewinding or fast-forwarding to a different point in the video by clicking on a tag in the image or the end screen of the video.
"seek"
Indicates that the moving image has been rewound or fast-forwarded to a different point in time by controlling the playback position of the moving image with a controller such as a seek bar.

(4) Switching Switching When a plurality of videos are simultaneously transmitted in parallel and viewed in a form in which a plurality of videos distributed at the same time are viewed on the viewer terminal 3 while being switched, it is possible that the videos are distributed in parallel. Indicates that the display has been switched from a certain video to another video.

(5) Leaving Indicates that the playback of the moving image has ended. It should be noted that cases where the viewing ends due to actions (1) to (4) described above are excluded.
In the present embodiment, even among the withdrawals, the behavior that triggered the withdrawal shall be acquired separately. For example, the following categories of behavior may be included:
"Screen close"
Indicates that the video display screen has been closed.
"Outview"
By scrolling the display screen, it indicates that the display area of the moving image is out of the window and the moving image cannot be visually recognized by the viewer.

The behavior of the viewer described above can be detected, for example, as an event on the video viewing screen. For example, a JavaScript embedded in a video viewing screen realized by a Web page detects a click or a video switching as an event, transmits the detected event to the analysis server 2, and the behavior analysis unit 213 Viewing information can be created by receiving . The behavior analysis unit 213 can register the viewing information in which the acquired items are set in the viewing information storage unit 232 .

The tag storage unit 233 (which can correspond to the structure storage unit of the present invention) stores information (hereinafter referred to as tag information) regarding tags set to moving images. The tag storage unit 233 can store tag information in association with, for example, a video ID that identifies a video. The tags are placed on the video display screen, and when the tags are clicked or tapped, for example, the displayed video can be switched or a screen showing preset product information can be displayed. or fast-forward or rewind to a particular transition of the video. The tag information includes the start time when the tag is displayed in the video, the end time when the tag display ends, the display position of the tag on the screen (it can be expressed as a point, or as information including the size of the tag). Also, when the tag is moved, information for specifying the moving trajectory may be included.), the shape of the tag (information for specifying the shape such as a polygon or a circle may also be included). Alternatively, the URL of an image or the like may be specified.), action (information for specifying the processing to be performed when a tag is operated on the screen. For example, a video to be displayed next, A URL of a web page may be set, or a specific point in the video for fast-forwarding or rewinding may be set.), parameters necessary for executing actions, etc. can be included.

In this embodiment, the action is set to play a moving image, and the parameter is set to a moving image ID indicating the moving image to be played. As a result, a tree-structured branching story can be set by combining a plurality of moving images.

The moving image distribution unit 211 distributes moving images. The video distribution unit 211 can distribute the video data stored in the video storage unit 231 in response to a request from the viewer terminal 3 or by broadcasting. For example, the video distribution unit 211 may distribute the video data by a streaming method, or may cause the viewer terminal 3 to download the file of the video data.

The behavior analysis unit 213 can display the screen 1 that displays the tree structure of the moving image group. In this embodiment, the tree structure can be grasped using tag information stored in the tag storage unit 233 . It is assumed that the root video (the video that is played first) is set in advance. Of the tag information corresponding to the root video, for those whose action is set to "play video", the next video to be played set in the parameter is the video linked from the root (second layer video). Then, for each moving image in the second layer, the moving image set in the parameter of the tag information related to "playing moving image" corresponding to the moving image can be specified as the moving image in the next layer. A moving image for which tag information related to "playing moving image" is not set can be a leaf of a tree structure. The behavior analysis unit 213 can display the screen 1 representing the tree structure based on the tag information stored in the tag storage unit 233, for example. The behavior analysis unit 213 can extract thumbnails of moving images and display them as nodes on the screen 1, as shown in FIG. Note that the behavior analysis unit 213 transmits the tree-structured video ID and/or thumbnail to the analyst's terminal (which may be the same as or different from the viewer terminal 3), and , the screen 1 may be constructed.

In addition, the behavior analysis unit 213 can identify the time point of withdrawal from the moving image for each viewer based on the viewing information, and can also identify the behavior after withdrawal. The behavior analysis unit 213 acquires, for example, each item of the viewing information related to the behavior of the viewer when viewing the moving image on the viewer terminal 3 . The behavior analysis unit 213 can receive items transmitted from the viewer terminal 3 by, for example, a script embedded in the screen displayed on the viewer terminal 3 .

Also, the behavior analysis unit 213 can acquire the behavior of the viewer during viewing from the behavior of the viewing information. Note that the behavior analysis unit 213 may, for example, analyze a viewing log in which a viewer views moving images, Web content, or the like to identify the behavior of the viewer.

In addition, the behavior analysis unit 213 can also output the type of behavior related to the time of withdrawal on the screen.

Also, the behavior analysis unit 213 can create statistical information for each moving image. For example, the behavior analysis unit 213 can calculate the number of views by counting the viewing information related to the behavior of “video playback”. The behavior analysis unit 213 counts the viewing information related to the behavior related to the interaction on the video display screen, such as “tag/end screen image click (story selection)” and “story HOME button click”, and calculates the number of interactions. can be calculated. For example, the behavior analysis unit 213 arranges the viewing information corresponding to the moving image ID of the moving image in chronological order for each viewer ID, and arranges the viewing information corresponding to the behavior of “playing the moving image” from the time of the viewing information related to the behavior of “playing the moving image”. The time up to the viewing information related to any of the above is calculated as the viewing time, and the viewing time for each viewer is averaged to calculate the average stay time. The behavior analysis unit 213 can display the statistical information on the screen 4 as shown in FIG. 2 by attaching it to the corresponding moving image. In addition, the behavior analysis unit 213 can create statistical information about all videos belonging to each layer of the tree structure. That is, the above-described statistical information can be calculated based on viewing information corresponding to each moving image belonging to the hierarchy. The behavior analysis unit 213 can display the calculated statistical information on the screen 4 so as to correspond to the hierarchy of the tree structure.

FIG. 6 is a diagram for explaining the operation of the viewing analysis system of this embodiment.

The analysis server 2 registers the moving images in the moving image information storage unit 231, and stores tag information (tag information including an action indicating the reproduction of the moving image and a parameter indicating the next moving image to be reproduced) related to branching of the moving images in the tag storage unit 233. , a moving image group related to a branching story is registered (S301), and moving images are distributed in order from a predetermined moving image (root of the tree structure) (S302). At the time of video distribution, the viewer terminal 3 can receive an interaction from the viewer, send viewing information related to the interaction to the analysis server 2, and the analysis server 2 can register the viewing information in the viewing information storage unit 232 ( S303).

The analysis server 2 periodically or in response to an instruction from the user creates a screen 1 showing the story of the video in a tree structure and transmits it to the terminal of the analyst (which may be the viewer terminal 3). (S304). The analysis server 2 can, for example, form a tree structure from the tag information, extract thumbnail images from the moving image data stored in the moving image storage unit 231, and arrange them on the screen 1 as nodes.

The analysis server 2 also periodically or in response to an instruction from the user, calculates statistical information related to the viewing status of the moving images for each moving image in the tree structure and for each layer in the tree structure (S305). The screen 4 displaying the statistical information in a tree structure can be transmitted to the analyst's terminal (which may be the viewer terminal 3) (S306).

As described above, according to the viewing analysis system of the present embodiment, it is possible to easily grasp the whole picture of branching stories by a tree-structured video group by displaying the tree structure.

In addition, according to the viewing analysis system of the present embodiment, the number of views, the number of withdrawals, the number of interactions, and the average viewing time can be drawn for each layer. Reaction can be grasped.

Although the present embodiment has been described above, the above-described embodiment is intended to facilitate understanding of the present invention, and is not intended to limit and interpret the present invention. The present invention can be modified and improved without departing from its spirit, and the present invention also includes equivalents thereof.

For example, the analysis server 2 can draw the breakdown of the interaction on the screen 4 for the designated layer or moving image. Further, for example, target hierarchies and moving images may be narrowed down using pop-ups, and what kind of interaction has occurred with respect to the narrowed down hierarchies and moving images may be displayed.

The analysis server 2 may also include an alert notification unit that issues an alert when the statistical information satisfies a predetermined condition. The alert notification unit can issue an alert when, for example, the ratio of the number of negative withdrawals to the total number of withdrawals exceeds a predetermined value. Alerts can, for example, send an email or message to the distributor.
