Description

The present invention relates to a moving image distribution device, a moving image distribution method, and a moving image distribution program.

In recent years, an environment is being developed in which individuals can easily distribute video content, and viewers can select what they want to see from a large number of video content. When a distributor distributes video content in real time (live broadcast), viewers can post comments, for example, to communicate between the distributor and viewers, and the distributor responds to viewers' reactions. This makes it possible for viewers to enjoy the realism that is unique to live broadcasting.

In particular, if the distributor and the viewer have common tastes, it is expected that active communication will take place and animation content will become more exciting. However, it is a time-consuming task for viewers to find content that matches their tastes from a huge amount of video content being distributed.

Therefore, conventionally, there has been proposed a technique for calculating a recommended value for each moving image user based on moving image attribute data corresponding to the content of the moving image and attribute data of the user of the viewer terminal (see, for example, Patent Document 1). ).

In addition, it extracts content tags that indicate the characteristics of each video scene, extracts topic tags that are related to each group in which video scenes are classified based on the content tags, and creates a user profile that indicates the user's preferences from the user's viewing operation. A technology has been proposed for creating recommendation information for recommending video scenes that match a user profile from video data based on content tags and topic tags (see Patent Document 2, for example).

The database 26 records at least user identification information and information on one or more preference tags associated with the user identification information. Also, one or more emotion images (communication images) associated with the preference tag can be recorded in the database. An emotion image may be associated with all preference tags, an emotion image may be associated with only some preference tags, or a common emotion image may be associated with a plurality of preference tags.

A preference tag is, for example, a tag attached to a user, and is a label for classifying users according to their hobbies and interests. Emotion images are images that express the feelings and intentions of viewers through characters, colors, etc., and are displayed on the content display screen based on the viewer's operation to facilitate communication between viewers and distributors. is a means of facilitating

The database 26 may be built in the video distribution device 20 or externally attached to the video distribution device 20, for example. The database 26 may include non-volatile storage media such as HDDs (Hard Disk Drives) and SSDs (Solid State Drives).

The user information management unit 25 refers to the external dictionary data, and when the dictionary data contains the candidate information of the preference tag acquired from the user terminal, associates the candidate information of the preference tag with the user identification information as a preference tag and stores the information in a database. 26 can be recorded.

For example, when the user accesses the video distribution site, logs in to the video distribution site, or registers as a member of the video distribution site, the user information management unit 25 requests editing of the registration information of the preference tag. When doing so, the user can be guided to register the preference tag by presenting a preference tag registration dialog to the user. Note that the user information management unit 25 can be configured to communicate with a corresponding user terminal via the third acquisition unit 213 or a communication unit (not shown).

3 and 4 are diagrams schematically showing examples of dialogs presented to the user when registering a preference tag.

The user information management unit 25 presents a dialog DG1 shown in FIG. 3 to the user, for example, and prompts the user to register a preference tag. When starting the registration of the preference tag, the user can select by clicking or tapping the button A1 labeled "set preference tag" with a finger, and proceed with editing such as registration of the preference tag. I can.

Further, the user information management unit 25 further presents, for example, a dialog DG2 shown in FIG. 4 to the user who selects the button A1, thereby enabling the user to register a preference tag. User information management unit 25 receives user input information from third acquisition unit 213 and transmits the received input information to dictionary management device 30 via fourth acquisition unit 214 . The dictionary management device 30 searches for words containing information input by the user from among the words registered in the dictionary data, and transmits the search results to the video distribution device 20 . The user information management unit 25 can receive words of search results from the dictionary management device 30 and present them to the user in, for example, a dialog DG2.

The dialog DG2 includes, for example, a text box TBX in which the user enters a word to be registered as a favorite tag, a list of favorite tags already registered for the user, and a button A2 stating "Complete setting". ,including.

For example, when the user enters "Tokyo" in the text box TBX, the user information management unit 25 acquires words containing "Tokyo" from the dictionary of the dictionary management device 30, and Words that can be registered as favorite tags can be displayed below. In FIG. 4, "Tokyo, Tokyo Station, Tokyo Tower, 23 wards of Tokyo, . . . " are displayed as examples of words that can be registered as preference tags. The user can input the favorite tag to be registered by referring to the presented words.

Note that, in the moving image distribution device 20 of the present embodiment, words that can be registered as preference tags are limited to words registered in the dictionary data of the dictionary management device 30 . That is, the user information management unit records the candidate information of the preference tag as a preference tag in association with the user identification information in the database 26 only when the candidate information of the preference tag requested by the user terminal is included in the external dictionary data. is configured to

For example, in the moving image distribution device 20 of the present embodiment, the user information management unit 25 is provided at the end of the text box TBX, for example, when the word input in the text box TBX is a word registered in a dictionary. may be configured to activate a "Register" button. By limiting the words that can be registered as preference tags, it is possible to suppress variation in preference tags registered for users who have common interests and preferences, and to more effectively classify users according to their interests and preferences. It becomes possible.

Note that, if there are similar words included in the dictionary data, the user information management unit 25 may preferentially present to the user terminals, for example, words registered as favorite tags by a large number of users. As a result, variations in registered preference tags can be further suppressed.

The user information management unit 25 also refers to, for example, information on preference tags that have already been registered for the user, the user's viewing history, recent registration rankings of preference tags, and the like, and selects content that matches the user's preferences. Such a favorite tag may be presented to make a recommendation. In this case as well, it is desirable that the user information management unit 25 presents to the user words that are recommended as preference tags from among the words registered in the dictionary of the dictionary management device 30 .

For example, when the user selects by clicking or tapping a "registration" button provided at the end of the text box TBX (requests registration), the user information management unit 25 stores the text information entered in the text box TBX. is acquired, and the acquired text information can be registered in the database 26 as information of the preference tag in association with the user identification information.

Also, in the dialog DG2, it is possible for the user to delete a preference tag that has already been registered. In the example shown in FIG. 4, up to 10 preference tags can be registered, and a user whose hobbies or preferences have changed can delete the already registered preference tags and register a new preference tag. It is possible to edit attached preference tags.

For example, when the user selects by clicking or tapping the deletion means (the area indicated by "x") provided at the end of the display of the preference tag that has already been registered, the user information management unit 25 deletes the database 26 to delete the corresponding preference tag associated with the user identification information from database 26 .

When the user selects by clicking or tapping the button A2 labeled "Complete setting" in the dialog DG2, the user information management unit 25 terminates the preference tag registration processing.

In addition, in response to a request from the generation unit 23, the user information management unit 25 stores the information of the preference tag associated with the user identification information of the distributor and the information of the preference tag associated with the user identification information of the viewer in a database. 26 and can be provided to the generation unit 23 .

The distribution control unit 22 controls the operation of real-time distribution of image data. The distribution control unit 22 can receive a distribution request from the viewer terminal 40 from the second acquisition unit 212 and control the distribution unit 24 so that the image data is distributed to the viewer terminal 40 . The distribution control unit 22 also includes, for example, a clock (not shown), compares time information obtained from the clock with a time frame assigned to real-time distribution of image data, and manages the start and end of real-time distribution of image data. You may In addition, the distribution control unit 22 starts real-time distribution so that the distribution of the moving image content is started in real time when the moving image data for distribution is received, and the distribution of the moving image content is finished when the moving image data for distribution is finished. and may manage termination.

The generation unit 23 receives real-time video data from the first acquisition unit 211 and receives input information from the viewer from the second acquisition unit 212 . Real-time video data is associated with, for example, tag information attached to video content and user identification information of a distributor. The generation unit 23 can receive tag information associated with the real-time video data and user identification information of the distributor together with the real-time video data.

The generation unit 23 can generate moving image data for distribution such that comments and emotional images based on input information input from the viewer terminal 40 are superimposed on the real-time moving image data. The generation unit 23 may synthesize the comment and the emotion image EM with the real-time moving image data using known techniques such as alpha blending and picture-in-picture, for example. Further, the generation unit 23 may generate moving image data for distribution so that the comment and the emotion image EM can be combined with the real-time moving image data at the viewer terminal 40 . The generation unit 23 transmits the generated moving image data for distribution to the distribution unit 24 .

For example, the generation unit 23 may resize a part or all of the screen of the reproduced video of the real-time moving image data, or may trim a part of the screen and combine it with the input information, or may resize the reproduced video of the real-time moving image data. may be combined with the evaluation information so that part of the screen is exposed and the rest is hidden. In addition, the generating unit 23 generates a plurality of pieces of moving image data for distribution with different images to be displayed so that a plurality of moving image data for distribution can be switched and distributed in response to a distribution request from the viewer terminal. 24 may be sent.

In addition, the generation unit 23 can generate a recent page for presenting a plurality of video contents currently being distributed in real time to the viewer.

FIG. 5 is a diagram schematically showing an example of a recent page presenting video content distributed in real time.

The recent page shown in FIG. 5 has an area A3 presenting a plurality of preference tags, and an area A4 presenting a plurality of video content distributed in real time by distributors who have registered the selected preference tags. include.

For example, the generation unit 23 acquires from the user information management unit 25 the information of the preference tags attached to the distributor of the video content distributed in real time, and presents a list of the preference tags in the area A3. In area A3, for example, a preference tag attached to a large number of real-time distributors (for example, a predetermined threshold or more) may be presented, or a preference tag associated with a large number of registrants may be presented. Often, preference tags may be presented that match the tastes and preferences of the viewer viewing the recent page.

A generation unit 23 presents, in an area A4, information of moving image contents distributed in real time by a distributor attached with a preference tag selected by a viewer from among the preference tags presented in the area A3, for example. The video content information presented in the area A4 may include, for example, video content thumbnails, video content titles, distributor names, the number of viewers, the number of followers, preference tags registered by the distributor, and the like. FIG. 5 shows, as an example, a display example when the favorite tag of "summer 2020 anime" is selected.

The generation unit 23 periodically updates the generated recent page and uploads it to the network. The viewer terminal 40 can access the recent page via the network, and the viewer selects the favorite tag of his/her interest from the area A3, and a plurality of video contents presented in the area A4. You can search for video content by distributors who match your tastes and preferences by referring to the information on .

The generation unit 23 can also generate moving image data for distribution such that a watch page is generated for each distributor. The watch page generated for each distributor includes information on video content currently distributed by the distributor, information on past video content distributed by the distributor, favorite tag information registered by the distributor, and It may include input information such as comments entered on video content.

FIG. 6 is a diagram schematically showing an example of a watch page generated for each distributor.

For example, the generation unit 23 can display the registration information of the distributor together with the watch page when the viewer views the moving image content. In the example shown in FIG. 6, the watch page includes an area A5 for displaying video content, an area A6 for displaying comments input by viewers, an area A7 for displaying tags attached to the video content, and an area A7 for displaying tags attached to the video content. and an area A8 for displaying preference tags attached to the person.

The generation unit 23 receives the real-time video data from the first acquisition unit 211 and the user identification information of the distributor associated with the real-time video data. The generation unit 23 also receives the input information by the viewer from the second acquisition unit 212 and the user identification information of the viewer associated with the input information.

Using the user identification information of the distributor, the generation unit 23 generates preference tag information associated with the user identification information of the distributor via the user information management unit 25 and emotion images associated with the preference tag of the distributor. and can be obtained. In addition, using the user identification information of the viewer, the generation unit 23 can acquire the information of the preference tag associated with the user identification information of the viewer via the user information management unit 25 .

The generation unit 23 uses the preference tag information associated with the user identification information of the distributor to create the preference tag information, the emotion image input means A11 corresponding to the preference tag, and the preference tag in the area A8 of the watch page. , and an input means A12 for requesting moving image content are displayed. By clicking or tapping the input means A12, the viewer can notify the distributor of the video content request for the corresponding preference tag. When the viewer clicks or taps the input means A11, the generator 23 displays a window displaying the emotion image corresponding to the preference tag near the area A8.

FIG. 7 is a diagram schematically showing an example of a window displaying emotion images corresponding to preference tags.

Here, an example of the emotion image EM corresponding to the distributor's favorite tag "yakiniku" is shown in the window. The viewer can select the emotion image EM displayed in the window by clicking or tapping it, and input it to the display screen of the moving image content.

The delivered real-time video data, the data for displaying comments, and the emotion video data for delivery can be combined and displayed on the viewer terminal 40 . The moving image data for distribution, the data for displaying comments, and the emotion moving image data for distribution may be combined in advance by the generation unit 23 and then distributed to the viewer terminal by the distribution unit 24 .

FIG. 8 is a diagram exemplifying how an emotion image is displayed on the display screen of moving image content.

For example, when the viewer selects an emotion image EM written as "iron plate", the generation unit 23 generates moving image data for distribution such that the emotion image EM is displayed on the display screen of the moving image content being broadcast. can do. A moving image is determined for each emotion image EM, and is set such that after performing a predetermined action within the display screen, it is guided out of the display screen or gradually disappears.

The operation of the emotion image EM is, for example, in the generation unit 23 of the video distribution device 20, the movement of objects obtained from the laws of classical mechanics (mass, velocity, friction, wind), etc., and physical calculations such as collisions and fluids. can be determined by For example, the generation unit 23 uses values such as mass, weight, elastic modulus, surface friction coefficient, and hardness set for each of the emotion images EM to calculate the motion of the emotion image EM based on the laws of physics. can be done.

The generation unit 23 can generate moving image data for distribution such that the emotion image EM is guided out of the display area or gradually disappears after the emotion image EM stays on the screen for a predetermined time. The generation unit 23 may adjust the predetermined time until the emotion image EM is no longer displayed on the screen, based on the number of the emotion image EM inserted into the content moving image per unit time.

Further, when the number of emotion images EM inserted into the moving image content per unit time exceeds a predetermined threshold value, the generation unit 23 may thin out the emotion images EM for display. As described above, by adjusting the display time and the number of displayed emotion images EM, the viewer is prevented from viewing moving image content. The generation unit 23 can control, for example, the number of emotional images EM that are input per a certain number of seconds, and the number of emotional images EM that stay on the video content display screen of the viewer terminal 40 . .

In addition, the generation unit 23 arranges transparent obstacles that cannot be visually recognized by the viewer on the display screen of the video content, and places the emotion image EM on the outside of the screen or in the surrounding area so as not to interfere with the viewing of the video content. can be guided to For example, the generation unit 23 may arrange a transparent object as an obstacle for the emotion image EM on the screen so that the bottom on which the emotion image EM falls is inclined with respect to the horizontal. As a result, for example, an emotional image EM that has fallen from the top of the screen to the bottom can be guided out of the screen by rolling or sliding down on a transparent object placed at the bottom.

Further, for example, the generating unit 23 may place a transparent object as an obstacle in the emotion image EM at the center of the screen. As a result, for example, the emotion image EM falling from the top to the bottom of the screen and the emotion image EM thrown into the screen do not cross the center of the screen, and the emotion image EM extending from the bottom to the top of the screen reaches the center of the screen. will disappear. Therefore, the viewer is not prevented from viewing the moving image content by the emotion image EM.

The generation unit 23 may allow, for example, viewers who have registered a common favorite tag with the distributor to input the emotion image EM corresponding to that favorite tag. The generation unit 23 may set the number of emotion images EM that can be inserted for each viewer, and may change the number of emotion images EM that can be inserted according to the level of the viewer.

By inserting emotional images EM corresponding to preference tags on the video content display screen, it becomes possible to communicate through common hobbies and preferences between the distributor and the viewer, and videos distributed in real time. It is possible to liven up the content.

In addition, the generation unit 23 compares the information of the preference tag associated with the distributor and the information of the preference tag associated with the viewer, and when there is a common preference tag, the common preference tag is determined. A notifier can be generated to notify on the watch page that a tagged viewer has started watching. In addition, in the moving image distribution apparatus 20 of the present embodiment, the notification means displayed on the watch page does not include information specifying the viewer, and respects the anonymity of the viewer.

Specifically, the generating unit 23 generates notification means for displaying, in an area A6 where comments are displayed, side by side with a telop A9 comment, for example, "One person has entered from the broadcaster's favorite 'Yakiniku'". Alternatively, in the video content display area A5, for example, a telop A10 stating "One person has entered from the broadcaster's favorite 'Yakiniku'" may be generated as notification means. Note that the generating unit 23 may generate the moving image data for distribution so as to display both the telop A9 and the telop A10, or may generate the moving image data for distribution so as to display at least one of the telop A9 and the telop A10. may be generated.

By notifying the broadcaster (and other viewers) of the presence of viewers with common taste tags, the broadcaster can develop broadcasts with content that takes into account the tastes of the viewers, enabling real-time It is expected that the video content being distributed will be exciting.
