Hereinafter, an audiovisual analysis system according to an embodiment of the present invention will be described. The viewing analysis system of the present embodiment is intended to analyze the viewing situation of a moving image.

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 the present embodiment. In the viewing analysis system of the present embodiment, where a plurality of moving images are distributed, the moving image to be played next to a certain moving image is determined, for example, by selecting an option displayed on the screen of the moving image. The video to be played next is specified in association with conditions such as which option is selected in advance. Therefore, a tree structure is composed of a plurality of moving images. By playing the video corresponding to the root of the tree structure and playing the video related to the next node by following the link according to the condition, the story as a whole can be branched. On the display screen 1 shown in FIG. 1, it is possible to display the structure of such a branch story by a plurality of moving images. For example, the moving image 11 which is the root node of the tree structure can be branched into two moving images 12 and 13 depending on the conditions.

FIG. 2 is a diagram showing an example of a screen 4 showing a viewing status of a moving image output by the viewing analysis system of the present embodiment. In the viewing analysis system of the present embodiment, by displaying the statistical values related to the viewing of the video for each video of the tree-structured video group in which the story branches and each layer of the tree structure, the story branches in the entire story. It makes it possible to understand how the viewer was browsing. The viewing statistics include, for example, the total number of views, the total number of interactions (clicks, etc., the viewer taking some action on the screen to input to the system), the total number of withdrawals, and the length of stay. The average value of (video viewing time) may be included. These statistical values can be calculated in units of predetermined periods (for example, any period such as 1 month or 3 months can be set).

Here, the withdrawal of the viewer means that the viewer has stopped watching the video. The withdrawal of the viewer is typically, for example, when the viewer closes the screen or window where the video was being viewed, but when the video is scrolled to the screen where the video was being viewed and the video is moved off the screen. Or, if you start watching content that is different from the video you were viewing, such as other videos or web pages, on the screen you were viewing the video, you will move (rewind) from the time of the video you were viewing to another time. And fast forward), it will be measured as a withdrawal of the video you were viewing.

In the example of FIG. 2, statistical information 21 is displayed for the moving image 21 related to the root of the tree structure, that is, the number of views is 5,000, the number of interactions (clicks) is 3,500, the number of exits is 1,500, and the average stay time is 01:24. ing. Similarly, for the moving images 12 and 13 branching from the moving image 11, the statistical information 22 and 23 for each of the moving images 12 and 13 are displayed.

Further, on the screen 4, statistical information about each layer of the tree structure is also displayed. For example, in the example of FIG. 2, the statistical information 24 for the first layer is displayed, and since the first layer is only the route, the same result as the statistical information 21 for the moving image 11 is displayed. .. Further, since the second layer can be branched into two moving images 12 and 13, the statistical information 25 that aggregates the viewing information about the two moving images 12 and 13 is displayed.

The moving image storage unit 231 can store moving image data in association with, for example, a moving image ID that identifies a moving image. The moving image data can be, for example, data recorded in a format such as MPEG.

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

The actions taken by the viewer while watching the video may include, for example, starting the playback of the video (playing the video), sending a comment, and the like. Further, in the present embodiment, the behavior included in the viewing information may include the following withdrawal. 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 to be positive, negative, or neither (neutral) for each type of withdrawal, such as giving a negative evaluation.

(1) "External transition"
Shows the screen transition to content other than the video you are watching.
In the present embodiment, among the external transitions, the action that triggered the screen transition to the external content is separately acquired. For example, the following behavioral categories may be included.
"Tag / end screen image click (direct external link)"
It indicates that the transition to the outside has been made by clicking the tag in the image or the end screen of the moving image.
"Click the button in the pop-up"

"Story PREV button click"
By clicking the button (PREV button) to return to the previous video of the story development of the video, it indicates that the video has changed.

(3) Transition in video Indicates that rewinding or fast-forwarding has been performed in the video that was being watched.
In the present embodiment, even in the transition in the moving image, the action that triggered the transition is separately acquired. For example, the following behavioral categories may be included.
"Tag / End screen image click (link in video)"
Indicates that the tag in the image or the end screen of the video has been rewound or fast-forwarded to different points in the video by clicking.
"seek"
It indicates that the video was rewound or fast-forwarded to different points in the video by controlling the playback position of the video by a controller such as a seek bar.

(4) Switching switching When a plurality of videos are transmitted in parallel and viewed in a form of switching and viewing a plurality of videos simultaneously distributed on the viewer terminal 3, the videos are distributed in parallel. Indicates that the display has been switched from one video to another.

(5) Withdrawal Indicates that the playback of the moving image has ended. In addition, the case where the viewing is terminated by the above-mentioned actions (1) to (4) is excluded.
In the present embodiment, even in the withdrawal, the action that triggered the withdrawal is separately acquired. For example, the following behavioral categories may be included.
"Screen close"
Indicates that the video display screen has been closed.
"Outview"
By scrolling the display screen, it is shown that the display area of the moving image has moved out of the window and the moving image cannot be seen by the viewer.

The above-mentioned behavior of the viewer can be detected as an event on the viewing screen of the moving image, for example. For example, JavaScript incorporated in the video viewing screen realized by the Web page detects clicks, video switching, etc. as events, and sends the detected events to the analysis server 2, and the behavior analysis unit 213 does this. 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 may correspond to the structural storage unit of the present invention) stores information related to tags set in the moving image (hereinafter, referred to as tag information). The tag storage unit 233 can store tag information in association with, for example, a moving image ID that identifies a moving image. The tag is placed on the video display screen, and depending on the operation such as clicking or tapping on the tag, for example, the video to be displayed can be switched or a screen showing preset product information is displayed. Actions such as fast-forwarding or rewinding to a specific transfer of video are performed. The tag information includes the start time when the tag is displayed in the video, the end time when the tag display ends, and the display position of the tag on the screen (may be represented by dots, or as information including the size of the tag). Also, when moving the tag, information for specifying the moving trajectory may be included), and also as information for specifying the shape of the tag (a shape such as a polygon or a circle). Alternatively, a URL such as an image may be specified), an action (information for specifying a process to be performed when a tag is operated on the screen, for example, a moving image to be displayed next or the like. The URL of the Web page may be set, a specific time point in the moving image for fast-forwarding or rewinding may be set), parameters necessary for executing the action, and the like can be included.

In the present embodiment, it is assumed that 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. This makes it possible to combine a plurality of videos to set a tree-structured branch story.

The video distribution unit 211 distributes the video. The moving image distribution unit 211 can distribute the moving image data stored in the moving image 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 have the viewer terminal 3 download the video data file.

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

In addition, the behavior analysis unit 213 can specify the time of withdrawal from the moving image based on the viewing information and the behavior after withdrawal for each viewer. The behavior analysis unit 213 acquires, for example, each item of viewing information regarding the behavior that the viewer has taken when viewing the moving image on the viewer terminal 3. The behavior analysis unit 213 can, for example, receive an item transmitted from the viewer terminal 3 by a script embedded in the screen displayed on the viewer terminal 3.

In addition, the behavior analysis unit 213 can acquire the behavior of the viewer at the time of viewing from the behavior of the viewing information. The behavior analysis unit 213 may, for example, analyze the viewing log in which the viewer has viewed a video, Web content, or the like to specify the behavior of the viewer.

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

In addition, the behavior analysis unit 213 can create statistical information for each moving image. The behavior analysis unit 213 can calculate the number of viewings by counting the viewing information related to the behavior of "video playback", for example. The behavior analysis unit 213 counts the viewing information related to the behavior related to the interaction with the video display screen, such as "tag / end screen image click (story selection)" and "story HOME button click", and counts the number of interactions. Can be calculated. For example, the behavior analysis unit 213 arranges the viewing information corresponding to the video ID of the video in the order of the time point for each viewer ID, and from the time of the viewing information related to the action of "video playback", the above-mentioned withdrawal action. The time until the time of the viewing information according to any of the above can be calculated as the viewing time, and the average staying time can be calculated by averaging the viewing time for each viewer. The behavior analysis unit 213 can display these statistical information on the screen 4 as shown in FIG. 2 in association with the corresponding moving image. In addition, the behavior analysis unit 213 can create statistical information about all the moving images belonging to the hierarchy for each hierarchy of the tree structure. That is, it is possible to calculate the statistical information as described above based on the viewing information corresponding to each of the moving images belonging to the layer. 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 illustrating the operation of the viewing analysis system of the present embodiment.

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

The analysis server 2 creates a screen 1 showing a story of a moving image in a tree structure on a regular basis or in response to an instruction from a user, and transmits the screen 1 to an analyst's terminal (which may be a viewer terminal 3). Can be done (S304). For example, the analysis server 2 can form a tree structure from 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 calculated and calculated statistical information related to the viewing status of the video for each video of the tree structure and for each layer of the tree structure on a regular basis or in response to an instruction from the user (S305). The screen 4 for displaying the statistical information in the tree structure can be transmitted to the terminal of the analyst (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 the branch story by the moving image group of the tree structure by displaying the tree structure.

Further, 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, so that the analyst can draw the number of viewers according to the depth of branching. You can grasp the reaction.

Although the present embodiment has been described above, the above embodiment is for facilitating the understanding of the present invention, and is not for limiting the interpretation of the present invention. The present invention can be modified and improved without departing from the spirit thereof, and the present invention also includes an equivalent thereof.

For example, the analysis server 2 may be configured to draw a breakdown of the interaction on the screen 4 for the designated hierarchy or moving image. Further, for example, the target hierarchy or moving image may be narrowed down by a pop-up, and what kind of interaction may have occurred with respect to the narrowed down hierarchy or moving image may be displayed.

Further, the analysis server 2 may be provided with an alert notification unit that issues an alert when the statistical information satisfies a predetermined condition. The alert notification unit can, for example, notify an alert when the ratio of the number of negative withdrawals to the total number of withdrawals is equal to or greater than a predetermined value. Alerts can, for example, send emails or messages to distributors.
