Description

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

In recent years, an environment has been established in which individuals can easily distribute video content, and viewers can select what they want to watch from a wide variety of video content. When a distributor distributes video content in real time (live broadcast), the distributor and the viewer can communicate with each other by, for example, the viewer posting a comment, enabling the distributor to respond according to the viewer's reaction and enabling the viewer to enjoy the sense of realism that is unique to live broadcast.

In particular, if a broadcaster and a viewer have common tastes, it is expected that communication will be active and video content will become more popular. However, it is a time-consuming task for viewers to find videos that match their tastes from the vast amount of video content available.

In view of this, a technique has been proposed in the past that calculates a recommended value for each video for a user based on video attribute data corresponding to the content of the video and attribute data of the user of the viewer terminal (see, for example, Patent Document 1).

In addition, a technology has been proposed that extracts content tags that indicate the characteristics of each video scene, extracts topic tags associated with each set of video scenes classified based on the content tags, creates a user profile that indicates the user's preferences from the user's viewing behavior, and creates recommendation information that recommends video scenes from video data that match the user profile based on the content tags and topic tags (see, for example, Patent Document 2).

In the case of distributed video content, even if a viewer is able to find video content that interests them, if their tastes do not match those of the video content distributor, it may not lead to active communication.

The present invention has been made in consideration of the above circumstances, and aims to provide a video distribution device, a video distribution method, and a video distribution program that stimulate communication between viewers and distributors and provide a service that enhances video content.

A video distribution device according to a first aspect of the present invention comprises an information acquisition unit that acquires user identification information and candidate information for favorite tags for classifying distributors or viewers according to their hobbies or likes from user terminals that may include distributor terminals and viewer terminals, a user information management unit that refers to external dictionary data in order to suppress variation in the favorite tags registered for the distributors or viewers, and when the candidate information for the favorite tags is included in the dictionary data, associates the candidate information for the favorite tags as the favorite tags with the user identification information acquired by the information acquisition unit and records it in a database, a recommended distributor selection unit that selects one or more distributors as recommended distributors based on the information of the favorite tags recorded in association with the user identification information of the viewer, and a recommendation sending unit that sends information of the recommended distributors selected by the recommended distributor selection unit to the viewer terminal.

In a video distribution device according to a second aspect of the present invention, the recommended distributor selection unit selects the recommended distributor depending on the matching state between the information of the favorite tag recorded in association with the viewer's user identification information and the information of the favorite tag recorded in association with the distributor's user identification information.

In the video distribution device according to a third aspect of the present invention, the recommended distributor selection unit selects the recommended distributor based on the favorite tag recorded in association with user identification information of a distributor currently broadcasting live.

A video distribution method according to a fourth aspect of the present invention includes the steps of acquiring user identification information and candidate information of favorite tags for classifying a distributor or a viewer according to hobbies or favorite things from a user terminal that may include a distributor terminal and a viewer terminal, and referring to external dictionary data in order to suppress variation in the favorite tags registered for the distributor or the viewer;
When the candidate information of the favorite tag is included in the dictionary data, the candidate information of the favorite tag is associated with the user identification information as the favorite tag and recorded in a database; and based on the information of the favorite tag recorded in association with the user identification information of the viewer,
The method includes the steps of: selecting one or more distributors as recommended distributors; and transmitting information on the recommended distributors selected by the recommended distributor selection unit to the viewer terminal.

A video distribution program according to a fifth aspect of the present invention causes a computer to function as: means for acquiring user identification information and candidate information for favorite tags for classifying distributors or viewers according to their hobbies or likes from a user terminal which may include a distributor terminal and a viewer terminal; means for referring to external dictionary data in order to suppress variation in the favorite tags registered for the distributors or the viewers, and when the candidate information for the favorite tags is included in the dictionary data, means for recording the candidate information for the favorite tags as the favorite tags in a database in association with the user identification information; means for selecting one or more distributors as recommended distributors based on the information of the favorite tags recorded in association with the user identification information of the viewer; and means for transmitting information of the recommended distributors selected by the recommended distributor selection unit to the viewer terminal.

The viewer terminal 40, for example, has at least one processor and a memory in which a program executed by the processor is recorded, and is configured to be able to realize various functions by software or a combination of software and hardware.

Viewer terminal 40 is capable of receiving content data such as video data and audio data from video distribution device 20, and presenting the content to the viewer using display means and audio means (not shown).

The dictionary management device 30 is, for example, a computer having at least one processor, a memory in which a program executed by the processor is recorded, and a dictionary data storage unit for accumulating dictionary data, and is configured to be able to realize various functions by software or a combination of software and hardware.

The dictionary management device 30 can, for example, record in the dictionary data storage unit a word input via a network in association with an explanation of the word, such as its definition, meaning, origin, etc.
The dictionary management device 30 can generate a web page for a user to search for any word from the dictionary data stored in the dictionary data storage unit and upload the generated web page onto the network. The user can access the web page to search for a desired word and learn its definition, meaning, and origin, and can also add or modify the definition, meaning, and origin.

Figure 2 is a block diagram showing an example of the configuration of a video distribution device according to the first embodiment.

The video distribution device 20 includes a receiving unit 21 including a first acquisition unit 211, a second acquisition unit 212, a third acquisition unit 213 and a fourth acquisition unit 214, a distribution control unit 22, a generation unit 23, a distribution unit 24, a user information management unit 25, and a database 26.

The video distribution device 20 may include, for example, a processor that executes a program to realize the functions of the above configuration and a memory that stores the program. The processor is typically a CP.
U (Central Processing Unit) and/or GPU (Gra
phics Processing Unit), microcomputer, FPGA (Field Programmable Gate Array
ld Programmable Gate Array), or DSP (Digit
The memory may be a multimedia signal processor (MPLS processor), etc. The memory also temporarily stores programs executed by the processor to realize the operations of the video distribution device, data used by the processor, and the like.

The video distribution device 20 may further include a communication unit (not shown) connectable to a network, and a data storage unit (not shown) for storing a large amount of data. The data storage unit may include a database 26. The data storage unit may be built into the video distribution device 20, or may be externally attached to the video distribution device 20. The data storage unit may be, for example, a hard disk drive (HDD) or a hard disk drive (HDD).
The data storage device may include a non-volatile storage medium such as a hard disk drive (HDD) or a solid state drive (SSD).

The receiving unit 21 can communicate with the distributor terminal 10, the dictionary management device 30, and the viewer terminal 40 via a network, and can include a first acquiring unit 211 and a second acquiring unit 212. For example, the receiving unit 21 receives video data from the distributor terminal 10 and acquires video data from the viewer terminal 40.
The receiving unit 21 transmits the delivery request received from the viewer terminal 40 to the delivery control unit 22 and the generating unit 23. The delivery request from the viewer terminal 40 may include identification information (user identification information) of the viewer or the viewer terminal 40, and identification information of the video content.

The first acquisition unit 211 is capable of receiving video data supplied from the distributor terminal 10 via the network. Specifically, the first acquisition unit 211 receives video data for real-time distribution sequentially transmitted from the distributor terminal 10. The first acquisition unit 211 transmits the received video data to the generation unit 23.

The second acquisition unit 212 is capable of receiving, from the viewer terminal 40, the user identification information of the viewer, a distribution request for video content, and input information corresponding to the video content.
The input information received by the second acquisition unit 212 from the viewer terminal 40 may include identification information of the video content being viewed, comments entered by the viewer, information (such as identification information) about the emotion image (communication image) EM to be entered into the content display screen, and operation information of the viewer's terminal 40 (such as the operation time length and the pressure applied during operation). The second acquisition unit 212 transmits the received input information to the generation unit 23. The second acquisition unit 212 can acquire the input information of the viewer terminal 40 in association with user identification information of the viewer (or the viewer terminal 40).

Incidentally, emotion images EM are images for expressing the viewer's emotions and intentions through text, color, etc., and are displayed on the content display screen based on the viewer's operation, facilitating communication between the viewer and the distributor.

The third acquisition unit 213 can receive a favorite tag registration request, input information (including candidate information for favorite tags) of users (distributors and viewers), and identification information (user identification information) of the users or user terminals from user terminals (distributor terminal 10 and viewer terminal 40). The third acquisition unit 213 transmits the acquired favorite tag registration request, user identification information, and user input information to the user information management unit 25.

The fourth acquisition unit 214 can receive user input information (including candidate information for favorite tags) from the user information management unit 25. Furthermore, the fourth acquisition unit 214 can refer to the dictionary data of the dictionary management device 30 based on the user input information, and receive words that can be registered as favorite tags and dictionary information including definitions of the words. The fourth acquisition unit 214 transmits the registerable words and the dictionary information of the words acquired from the dictionary management device 30 to the user information management unit 25.

The database 26 records at least user identification information and information on one or more favorite tags associated with the user identification information. The database may also record one or more emotion images (communication images) associated with the favorite tags. Note that emotion images may be associated with all favorite tags, emotion images may be associated with only some of the favorite tags, or a common emotion image may be associated with multiple favorite tags.

A favorite tag is, for example, a tag given to a user, and is a label for classifying users according to their hobbies and favorite things. An emotion image is an image for expressing the viewer's feelings and intentions using characters, colors, etc., and is inserted into the content display screen based on the viewer's operation, facilitating communication between the viewer and the distributor.

The database 26 may be, for example, built in the video distribution device 20 or may be externally attached to the video distribution device 20. The database 26 may be, for example, stored in a hard disk drive (HDD).
The internal memory may include a non-volatile storage medium such as a hard disk drive (HDD) or a solid state drive (SSD).

The user information management unit 25 can refer to external dictionary data, and when the candidate information for favorite tags obtained from the user terminal is included in the dictionary data, it can record the candidate information for favorite tags in the database 26 as favorite tags in association with the user identification information.

The user information management unit 25 can present the user with a dialogue for registering favorite tags and guide the user to register favorite tags, for example, when the user accesses a video distribution site, logs in to the video distribution site, registers as a member of the video distribution site, or requests editing of registration information for favorite tags. The user information management unit 25 can be configured to be able to communicate with a corresponding user terminal via the third acquisition unit 213 or a communication unit (not shown).

3 and 4 are diagrams each showing an example of a dialogue presented to the user when registering a favorite tag.

The user information management unit 25 presents the user with, for example, a dialogue DG1 shown in Fig. 3, and prompts the user to register favorite tags. When the user starts to register favorite tags, the user selects a button A1 labeled "Set favorite tags" by clicking or tapping with a finger,
You can proceed with editing, such as registering favorite tags.

4 to the user who selected button A1, allowing the user to register favorite tags. The user information management unit 25 receives user input information from the third acquisition unit 213 and transmits the received input information to the dictionary management device 30 via the fourth acquisition unit 214. The dictionary management device 30 searches for words that include the user's input information from among 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 the search result words from the dictionary management device 30 and present them to the user in, for example, the dialog DG2.

Dialog DG2 includes, for example, a text box TBX in which the user inputs words that he or she wishes to register as favorite tags, a list of favorite tags that have already been registered for the user, and a button A2 labeled "Complete settings."

For example, when a user inputs "Tokyo" in the text box TBX, the user information management unit 2
5 can obtain words that contain "Tokyo" from among those recorded in the dictionary of the dictionary management device 30, and display words that can be registered as favorite tags under the text box TBX. In Fig. 4, "Tokyo, Tokyo Station, Tokyo Tower, Tokyo 23 Wards, ..." are displayed as examples of words that can be registered as favorite tags. The user can input the favorite tags that he or she wants to register by referring to the presented words.

In the video distribution device 20 of the present embodiment, words that can be registered as favorite tags are limited to words registered in the dictionary data of the dictionary management device 30. In other words, the user information management unit is configured to record the candidate information of a favorite tag as a favorite tag in the database 26 in association with the user identification information only when the candidate information of a favorite tag requested to be registered from the user terminal is included in the external dictionary data.

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

In addition, if there is a similar word included in the dictionary data, the user information management unit 25
For example, a word that is registered as a favorite tag by a large number of users may be given priority and presented to the user terminal, thereby making it possible to further reduce variation in the favorite tags that are registered.

The user information management unit 25 may also present and recommend favorite tags that are likely to match the user's preferences, for example, by referring to information on favorite tags already registered for the user, the user's viewing history, a recent registration ranking of favorite tags, etc. In this case, too, it is desirable for the user information management unit 25 to present to the user words to be recommended as favorite tags from among those registered in the dictionary of the dictionary management device 30.

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

In addition, the dialogue DG2 allows a user to delete favorite tags that have already been registered. In the example shown in Fig. 4, up to 10 favorite tags can be registered, and a user whose hobbies or preferences have changed can edit the favorite tags attached to themselves by deleting the favorite tags that have already been registered and registering new favorite tags.

For example, a deletion means ("x") provided at the edge of the display of favorite tags that the user has already registered may be used.
When the user selects the preferred tag by clicking or tapping on the preferred tag area (the area displayed as “Favorite Tag”), the user information management unit 25 can access the database 26 and delete the corresponding preferred tag associated with the user identification information from the database 26.

When the user selects, by clicking or tapping, button A2 labeled "Complete settings" in dialog DG2, user information management unit 25 ends the favorite tag registration process.

In addition, in response to a request from the generation unit 23, the user information management unit 25 can read out information on favorite tags associated with the distributor's user identification information and information on favorite tags associated with the viewer's user identification information from the database 26 and provide the information to the generation unit 23.

The distribution control unit 22 controls the operation of real-time distribution of image data.
can receive a distribution request from the viewer terminal 40 from the second acquisition unit 212 and control the distribution unit 24 so that image data is distributed to the viewer terminal 40.
For example, a clock (not shown) may be included, and time information obtained from the clock may be compared with a time frame allocated to the real-time distribution of image data to manage the start and end of the real-time distribution of image data. The distribution control unit 22 may also manage the start and end of real-time distribution so that distribution of video content is started in real time when video data for distribution is received, and distribution of video content is ended when the video data for distribution ends.

The generating unit 23 receives real-time video data from the first acquiring unit 211 and outputs the real-time video data to the second acquiring unit 212.
The real-time video data is associated with, for example, tag information attached to the video content and user identification information of the distributor.
3 can receive tag information and user identification information of the distributor associated with the real-time video data together with the real-time video data.

The generating unit 23 can generate video data for distribution so that comments and emotion images based on input information input from the viewer terminal 40 are superimposed on the real-time video data. The generating unit 23 may synthesize the comments and emotion images EM with the real-time video data using known techniques such as alpha blending and picture-in-picture. The generating unit 23 may also generate video data for distribution so that the comments and emotion images EM can be synthesized with the real-time video data at the viewer terminal 40. The generating unit 23 transmits the generated video data for distribution to the distributing unit 24.

The generating unit 23 may, for example, resize a part or all of the screen of the playback image of the real-time video data, or trim a part of the screen and combine it with the input information, or may combine it with the evaluation information so that a part of the screen of the playback image of the real-time video data is exposed and the remaining part is hidden. Furthermore, the generating unit 23 may generate a plurality of video data for distribution, each of which has a different image to be displayed, and transmit it to the distributing unit 24, in order to enable switching and distribution of a plurality of video data for distribution in response to a distribution request from a viewer terminal.

Furthermore, 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 illustrating an example of a recent page that presents video content being distributed in real time.

The recent page shown in Figure 5 includes an area A3 in which a plurality of favorite tags are presented, and an area A4 in which a plurality of video contents being distributed in real time by distributors who have registered the selected favorite tags are presented.

The generation unit 23, for example, obtains information on favorite tags attached to distributors of video content being distributed in real time from the user information management unit 25, and presents a list of favorite tags in area A3. In area A3, for example, favorite tags that are attached to a large number of distributors in real time (e.g., those that are attached above a predetermined threshold value) may be presented, favorite tags with a large number of registered users may be presented, or favorite tags that match the hobbies and preferences of viewers viewing the recent page may be presented.

The generation unit 23 presents, for example, in area A4, information on video content being distributed in real time by a distributor to which a favorite tag selected by a viewer from among the favorite tags presented in area A3 has been added. The information on the video content presented in area A4 may include, for example, a thumbnail of the video content, the title of the video content, the name of the distributor, the number of viewers, the number of followers, favorite tags registered by the distributor, etc. FIG. 5 shows an example of a display when the favorite tag "2020 Summer Anime" is selected as an example.

The generation unit 23 periodically updates the generated recent page and uploads it onto the network. The viewer terminal 40 can access the recent page via the network, and the viewer can select a favorite tag that interests him/her from area A3, refer to information on a plurality of video content items presented in area A4, and search for video content items by distributors whose hobbies and preferences match his/hers.

The generating unit 23 can generate video data for distribution so that a watch page is generated for each distributor. The watch page generated for each distributor can include information on video content currently being distributed by the distributor, information on past video content distributed by the distributor, favorite tag information registered by the distributor, and input information such as comments input by viewers on the video content.

Figure 6 is a schematic diagram showing an example of a watch page generated for each broadcaster.

For example, the generation unit 23 may display the registration information of the distributor together with the watch page when the viewer watches the video content. In the example shown in Fig. 6, the watch page includes at least an area A5 that displays the video content, an area A6 that displays comments input by the viewer, an area A7 that displays tags attached to the video content, and an area A8 that displays favorite tags attached to the distributor.

The generation unit 23 receives the real-time video data together with the user identification information of the distributor associated with the real-time video data from the first acquisition unit 211. In addition, the generation unit 23
The information input by the viewer is received from the second acquisition unit 212 together with the user identification information of the viewer associated with the input information.

The generation unit 23 can use the user identification information of the distributor to obtain information on favorite tags associated with the user identification information of the distributor and emotion images associated with the favorite tags of the distributor via the user information management unit 25. The generation unit 23 can also use the user identification information of the viewer to obtain information on favorite tags associated with the user identification information of the viewer via the user information management unit 25.

The generation unit 23 uses the information of the favorite tag associated with the user identification information of the distributor to display the information of the favorite tag, an input means A11 of an emotion image corresponding to the favorite tag, and an input means A12 of a request for video content of the favorite tag in the area A8 of the watch page. A viewer can notify the distributor of a request for video content related to the corresponding favorite tag by clicking or tapping the input means A12. When the viewer clicks or taps the input means A11, the generation unit 23 displays a window displaying an emotion image corresponding to the favorite tag near the area A8.

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

Here, an emotion image E corresponding to the streamer's favorite tag "Yakiniku" is displayed in the window.
1 shows an example of an emotion image EM displayed in a window. A viewer can select an emotion image EM displayed in the window by clicking or tapping it, and insert it into the video content display screen.

The distributed real-time video data, data for displaying comments, and distribution emotion video data can be synthesized and displayed on the viewer terminal 40.
In the third embodiment, the video data for distribution, data for displaying comments, and emotion video data for distribution may be synthesized in advance, and then distributed to the viewer terminal by the distribution unit 24.

FIG. 8 is a diagram showing an example of an emotion image being inserted on a display screen of a video content.

For example, when a viewer selects an emotion image EM labeled "sure thing," the generating unit 23 can generate distribution video data so that the emotion image EM is inserted into the display screen of the video content being broadcast. Each emotion image EM has a predetermined video, and is set to perform a predetermined action on the display screen before being guided outside the display screen or gradually disappearing.

The movement of the emotion image EM can be determined, for example, by the generation unit 23 of the video distribution device 20 performing physical calculations of the movement of objects obtained from the laws of classical mechanics (mass, speed, friction, wind), collisions, fluids, etc. For example, the generation unit 23 can calculate the movement of the emotion image EM based on the laws of physics using values of mass, weight, elasticity, surface friction coefficient, hardness, etc. set for each emotion image EM.

The generating unit 23 can generate the distribution video data so that the emotion image EM is guided out of the display area or gradually disappears after staying on the screen for a predetermined time. The generating unit 23 may adjust the predetermined time until the emotion image EM is no longer displayed on the screen based on the number of emotion images EM per unit time that are input into the content video.

Furthermore, the generation unit 23 may thin out the emotion images EM when the number of emotion images EM added to the video content per unit time exceeds a predetermined threshold. As described above, by adjusting the time for which the emotion images EM are displayed and the number of emotion images EM to be displayed, the viewer is not prevented from watching the video content. For example, the generation unit 23 may adjust the number of emotion images EM added per certain number of seconds,
It is possible to control the number of emotion images EM that are displayed on the display screen of the video content.

Furthermore, the generating unit 23 can arrange a transparent obstacle on the display screen of the video content that is not visible to the viewer, and can guide the emotion image EM to the outside of the screen or to a surrounding area so as not to interfere with the viewing of the video content. For example, the generating unit 23 can arrange a transparent object on the screen as an obstacle to the emotion image EM, thereby guiding the emotion image E
The bottom of the screen on which M falls may be inclined with respect to the horizontal. This allows, for example, an emotion image EM falling from the top of the screen to the bottom to be guided outside the screen by rolling or sliding down on a transparent object placed at the bottom.

Also, for example, the generator 23 may place a transparent object in the center of the screen as an obstacle to the emotion image EM. This prevents, for example, an emotion image EM falling from the top of the screen to the bottom, or an emotion image EM thrown onto the screen from crossing the center of the screen, and an emotion image EM extending from the bottom to the top of the screen from reaching the center of the screen. Therefore, the emotion image EM will not hinder the viewer from watching the video content.

For example, the generation unit 23 may enable a viewer who has registered a favorite tag common to the distributor to upload an emotion image EM corresponding to the favorite tag. The generation unit 23 may also set the number of emotion images EM that can be uploaded for each viewer, and may further change the number of emotion images EM that can be uploaded depending on the level of the viewer.

By inserting an emotion image EM corresponding to a favorite tag on a display screen of a moving image content, communication through common hobbies and preferences between a distributor and a viewer becomes possible, and the moving image content being distributed in real time can be enlivened.

Furthermore, the generation unit 23 can compare information on favorite tags associated with the distributor with information on favorite tags associated with the viewer, and when there is a common favorite tag, generate a notification means for notifying on the watch page that a viewer who has added the common favorite tag has started watching. Note that in the video distribution device 20 of this embodiment, the notification means displayed on the watch page does not include information that identifies the viewer, and the anonymity of the viewer is respected.

Specifically, the generating unit 23 may generate a notification means for displaying, for example, a caption A9 stating "One person has entered from the broadcaster's preference "Yakiniku"" alongside the comment in the area A6 displaying the comment, and may generate, for example, a caption A10 stating "One person has entered from the broadcaster's preference "Yakiniku"" as a notification means in the display area A5 of the video content. Note that the generating unit 23 may generate the video data for distribution so as to display both the caption A9 and the caption A10, or may generate the video data for distribution so as to display at least one of the caption A9 and the caption A10.

By notifying broadcasters (and other viewers) of the presence of viewers who have shared preference tags, broadcasters will be able to develop content that takes into account the preferences of viewers, which is expected to increase excitement about video content being distributed in real time.

In addition, the generation unit 23 may periodically check the favorite tags attached to viewers of the video content during real-time video content distribution and generate statistical data (e.g., 0% of viewers have favorite tag A, △% have favorite tag B, ..., etc.). For example, the generation unit 23 may calculate the favorite tags attached to viewers of the video content and the ratio of viewers who attached the favorite tags during or after the distribution of the real-time video content, and present it to the distributor by, for example, displaying it on a watch page. By understanding what kind of viewers are watching their video content, the distributor can consider the content of the video content to liven up the video content.

The generating unit 23 may generate, for example, a community page that presents information about users who have a common favorite tag.

FIG. 9 is a diagram showing an example of a community page presenting information about users who have been tagged with a common preference.

Here, a community page presenting information on users who have added the common favorite tag "yakiniku" is shown as an example. The community page may display icons of the favorite tags and at least a part of the dictionary information of the favorite tags. The favorite tag icons may be configured so that the users who added the favorite tags can set them from their user terminals.

For example, on a community page, the generation unit 23 may arrange user information so that users who have a lot of common favorite tags with the viewer are ranked at the top, or so that users who are distributing video content in real time are ranked at the top, or so that users with a large number of followers are ranked at the top, and the viewer may be able to switch the order in which users are arranged.

Viewers of the community page can easily find users who share the same hobbies and tastes as themselves from the presented user information. This makes it possible to match viewers with similar hobbies and tastes with broadcasters in advance, even outside the period when videos are being broadcast in real time, which is expected to increase the popularity of video content.

In addition, the generating unit 23 may generate a page where users who have registered a common favorite tag can communicate with each other using a chat function, even during periods other than when real-time video content is being broadcast. For example, by having a lively chat among multiple users, including a distributor and a viewer, the distributor can increase the number of his/her followers.
It is believed that this will lead to increased popularity of streamers' real-time video content.

The distribution unit 24 is communicably connected to the network, receives video data for distribution from the generation unit 23, and distributes it to the viewer terminal 40 corresponding to the distribution request. The distribution unit 24 is controlled by the distribution control unit 22, for example, in terms of the distribution destination of the video data for distribution. For example, a viewer can view video content being broadcast by browsing the watch page of a distributor, and can make a distribution request to the video distribution device 20 by accessing the URL of the watch page on the viewer terminal 40, for example.

The distribution unit 24 may immediately discard the video data for distribution that has already been distributed, or may buffer it for a predetermined period of time to enable replay or slow-motion playback, for example.

Next, we will explain the operation of the video distribution device of the first embodiment.

FIG. 10 is a flowchart illustrating an example of an operation for registering a user's favorite tag in the video distribution device according to the first embodiment.

The third acquisition unit 213 of the video distribution device 20 acquires user identification information and candidate information of favorite tags from the user terminals (from the distributor terminal 10 and the viewer terminal 40) (step SA
1) The third acquisition unit 213 transmits the acquired information to the user information management unit 25.

The user information management unit 25 refers to the dictionary data in the dictionary management device 30, and when the candidate information for the favorite tag is included in the dictionary data, records the candidate information for the favorite tag as a favorite tag in the database 26 in association with the user identification information (step SA2).

In addition, if the acquired candidate information for a favorite tag is not included in the dictionary data, the user information management unit 25 can present to the user terminal words similar to the candidate information for a favorite tag included in the dictionary data.

FIG. 11 is a flowchart illustrating an example of an operation of distributing live video content in the video distribution device according to the first embodiment.

The first acquisition unit 211 acquires real-time video data and user identification information of the distributor from the distributor terminal 10 , and transmits them to the generation unit 23 .

The generation unit 23 uses the user identification information of the distributor to obtain information on the distributor's favorite tags via the user information management unit 25. The generation unit 23 uses the information on the distributor's favorite tags and the real-time video data to generate video data for distribution that displays the distributor's watch page, and updates the recent page using the real-time video data and the information on the distributor's favorite tags (step SB1).

When the second acquisition unit 212 acquires the distribution request and the viewer's user identification information from the viewer terminal 40, it transmits the viewer's user identification information to the generation unit 23 (step SB2).

Using the user identification information of the viewer, the generation unit 23 acquires information on the viewer's favorite tag via the user information management unit 25. The generation unit 23 compares the information on the favorite tag of the distributor with the information on the favorite tag of the viewer, and when there is a common favorite tag, generates video data for distribution further including a notification means that a viewer who has added the common favorite tag has started viewing, and transmits the data to the distribution unit 24 (step SB3).

The distribution unit 24 distributes the distribution video data generated in step SB1 or step SB3 to the corresponding viewer terminal 40 under the control of the distribution control unit 22 (step SB4
).

While acquiring real-time video data from the distributor terminal 10, the video distribution device 20 periodically performs steps SB1 to SB4 to distribute real-time video content.

As described above, according to this embodiment, by managing user information by attaching preference tags to each user according to their hobbies and preferences, it is possible to easily match viewers with distributors. As a result, it is possible to provide a video distribution device, a video distribution method, and a video distribution program that provide a service that stimulates communication between viewers and distributors and enhances video content.

may be independent of.

The video distribution device 20 may include, for example, a processor that executes a program to realize the functions of the above configuration and a memory that stores the program. The processor is typically a CP.
U (Central Processing Unit) and/or GPU (Gra
phics Processing Unit), microcomputer, FPGA (Field Programmable Gate Array
ld Programmable Gate Array), or DSP (Digit
The memory may be a multimedia signal processor (MPLS processor), etc. The memory also temporarily stores programs executed by the processor to realize the operations of the video distribution device, data used by the processor, and the like.

The video distribution device 20 may further include a communication unit (not shown) connectable to a network, and a data storage unit (not shown) for storing a large amount of data. The data storage unit may include a database 26. The data storage unit may be built into the video distribution device 20, or may be externally attached to the video distribution device 20. The data storage unit may be, for example, a hard disk drive (HDD).
The hard disk drive may include a non-volatile storage medium such as a hard disk drive (HDD) or a solid state drive (SSD).

The recommended distributor selection unit 251 selects one or more distributors as recommended distributors based on information of favorite tags recorded in association with the viewer's user identification information. A recommended distributor indicates a distributor recommended to a viewer based on the viewer's favorite tags. A recommended distributor includes, for example, a distributor recommended based on a matching state with the viewer's favorite tags. The matching state includes, for example, a high degree of matching of favorite tags or a high tendency of matching of favorite tags. A recommended distributor includes a distributor who has registered a favorite tag that is common to the viewer's favorite tags.

According to this example, the recommended distributor selection unit 251 can perform matching between the distributor and the viewer based on the favorite tags without requiring any operation by the distributor. As a result,
The video distribution device 20 can provide the matching result by the recommended distributor selection unit 251 to the viewer terminal 40. This allows the viewer to easily find a distributor whose hobbies and tastes match. This is expected to increase the frequency with which viewers watch video content from distributors whose hobbies and tastes match, and to increase interest in the video content.

The recommended distributor selection unit 251 selects one or more distributors as recommended distributors, for example, depending on the degree of match between information of a favorite tag associated with the viewer and information of a favorite tag associated with the distributor.

According to this example, the recommended distributor selection unit 251 can perform matching based on the matching state of the favorite tags between the distributor and the viewer. As a result, the video distribution device 20 can provide the viewer terminal 40 with a matching result according to the matching state of the favorite tags by the recommended distributor selection unit 251. This allows the viewer to easily find a distributor with similar hobbies and preferences based on the common favorite tags. This is expected to increase the frequency with which viewers watch video content from distributors with similar hobbies and preferences, and to increase the popularity of the video content.

The matching state may be a degree of matching. In this case, the recommended distributor selection unit 251 compares information of a favorite tag associated with a viewer with information of a favorite tag associated with a distributor,
The number of common favorite tags is acquired as the degree of coincidence. For example, the degree of coincidence may be higher as the number of common favorite tags increases. The recommendation distributor selection unit 251 selects one or more of the common favorite tags according to the degree of coincidence.
Alternatively, a plurality of distributors may be selected as recommended distributors. For example, the recommended distributor selection unit 251 may select the recommended distributors in descending order of the degree of matching.

According to this example, the recommended distributor selection unit 251 can perform matching based on the degree of matching of the favorite tags between the distributor and the viewer. As a result, the video distribution device 20 transmits the matching result according to the degree of matching of the favorite tags by the recommended distributor selection unit 251 to the viewer terminal 4.
0. This allows viewers to easily find more compatible distributors, such as those with many common favorite tags. This is expected to increase the frequency with which viewers watch video content from distributors whose hobbies and preferences match theirs, and to boost interest in video content.

The matching mode may be a matching tendency. In this case, the recommended distributor selection unit 251 compares the information of the favorite tag associated with the viewer with the information of the favorite tag associated with the distributor, and acquires distributors having a specific favorite tag in common as a matching tendency. The specific favorite tag includes, for example, a rare favorite tag with a small number of registered users, or a new favorite tag with a short elapsed time since registration. The matching tendency includes the number of users registered for the specific favorite tag, or the elapsed time since registration of the specific favorite tag. For example, the matching tendency may be higher as the number of users registered for the specific favorite tag is smaller, and higher as the elapsed time since registration of the specific favorite tag is shorter.
The recommended distributor selection unit 251 selects one or more distributors as recommended distributors according to the matching tendency. For example, the recommended distributor selection unit 251 may select the recommended distributors in descending order from the distributors with the highest matching tendency.

According to this example, the recommended distributor selection unit 251 can perform matching based on the tendency of matching between favorite tags between distributors and viewers. As a result, the video distribution device 20 can provide the viewer terminal 40 with a matching result according to the tendency of matching between favorite tags by the recommended distributor selection unit 251. This allows the viewer to easily find a distributor with whom they have a better compatibility, such as a distributor with a rare favorite tag in common. This is expected to increase the frequency with which viewers watch video content from distributors with similar hobbies and preferences, and to increase the popularity of the video content.

The recommended distributor selection unit 251 may select one or more distributors as recommended distributors from among all distributors based on information on a favorite tag associated with the viewer. All distributors include broadcasters currently broadcasting video content in a live broadcast and broadcasters other than those currently broadcasting live. In this case, the recommended distributor selection unit 251 selects one or more distributors as recommended distributors based on information on a favorite tag associated with the viewer and information on the favorite tags of all distributors.

According to this example, the recommended distributor selection unit 251 can perform matching based on the tendency of matching between the favorite tags of all distributors and the viewer. As a result, the video distribution device 20 can provide the viewer terminal 40 with the matching results with all distributors by the recommended distributor selection unit 251. This allows the viewer to easily find a distributor whose hobbies and preferences match based on information on video content currently being distributed by the recommended distributor and information on past video content distributed by the recommended distributor. This is expected to increase the frequency with which viewers watch video content from distributors whose hobbies and preferences match, and to increase the excitement of the video content.

The recommended distributor selection unit 251 may select one or more distributors as recommended distributors from among the distributors currently broadcasting live, based on information on a favorite tag associated with the viewer. In this case, the recommended distributor selection unit 251 selects one or more distributors as recommended distributors, based on information on a favorite tag associated with the viewer and information on a favorite tag of the distributor currently broadcasting live.

According to this example, the recommended distributor selection unit 251 can perform matching based on the tendency of matching between the favorite tags of the broadcaster and the viewer during live broadcast. As a result, the video distribution device 2
The service 200 can provide the viewer terminal 40 with the matching results with live broadcasters by the recommended broadcaster selection unit 251. This allows the viewer to easily find a broadcaster whose hobbies and preferences match based on the information on the video content currently being broadcast by the recommended broadcaster. This is expected to increase the frequency with which viewers watch video content from broadcasters who are live broadcasting and who match their hobbies and preferences, and to increase the popularity of the video content.

In addition, the recommended distributor selection unit 251 may select a recommended distributor excluding a specific distributor. For example, the recommended distributor selection unit 251 may select a recommended distributor excluding distributors who follow each other. According to this example, the video distribution device 20:
It is possible to recommend new distributors that the viewer is not following, so that the viewer can watch video content from new distributors that match his or her hobbies and preferences, and the video distribution device 20 can stimulate communication between the viewer and the distributors.

The recommended distributor selection unit 251 may select one or more distributors as recommended distributors, for example, when a user accesses a video distribution site, when a user logs in to a video distribution site, when a user registers as a member of the video distribution site, when a user requests editing of registration information of favorite tags, etc. The recommended distributor selection unit 251 may be configured to be able to communicate with a corresponding user terminal via the third acquisition unit 213 or a communication unit not shown.

The recommendation sending unit 252 sends information about the recommended distributor selected by the recommended distributor selecting unit 251 to the viewer terminal 40. The recommendation sending unit 252 may send the information about the recommended distributor to the generating unit 23 in response to a request from the generating unit 23.

The generation unit 23 can generate a recommendation page for presenting the information of the recommended distributors to the viewer by acquiring the information of the recommended distributors via the recommendation transmission unit 252. The generation unit 23 can generate a recommendation page for each viewer.

13 is a diagram showing an example of a recommended distributor window showing information on a recommended distributor included in a recommended page. A recommended page may include a plurality of recommended distributor windows. The number of recommended distributor windows may be preset.
It may be set according to the number of recommended distributors selected by the recommended distributor selection unit 251.

The generation unit 23 may generate a recommendation page every time a recommended distributor is selected by the recommended distributor selection unit 251. The generation unit 23 may generate a recommendation page, for example, when a user accesses a video distribution site, when a user logs in to a video distribution site, when a user registers as a member of the video distribution site, when a user requests editing of registration information of favorite tags, etc.

In the example shown in Figure 13, the recommended distributor window includes at least an area A21 that displays video content, an area A22 that displays the status of the video content, an area A23 that displays the time, an area A24 that displays numbers related to the video content, an area A25 that displays numbers related to viewer comments, an area A26 that displays the matching status of favorite tags, an area A27 that displays common favorite tags, and an area A28 that displays information identifying the recommended distributor.

The video content displayed in the area A21 may be, for example, a thumbnail of the video content,
Or a still image at a certain point in time of the video content. Area A22 may be a text display such as "LIVE" indicating that the video content is a live broadcast. The status of the video content may include live broadcast, after broadcast, before broadcast, etc. Area A23 may include the elapsed time from the start of real-time distribution, or the time until the start of real-time distribution, etc. Area A24 may include the number of viewers of the video content, the number of subscribers of the video content, or the number of followers of the distributor, etc. Area A25 may include the number of comments posted by viewers of the video content, etc. Area A26 may include the degree of agreement or tendency of agreement of favorite tags between the viewer and the distributor, etc. Area A27 may include common favorite tags and the number of subscribers of the favorite tags, etc. Area A28 may include an icon for identifying the distributor, the name of the distributor, etc.

In addition to the above information, the recommended distributor window may include information such as the title of the video content, and favorite tags other than the common favorite tags registered by the distributor.

13 shows an example of the display of the recommended distributor window when "2020 Summer Anime,""Ocean,""Yakiniku," and "Shiba Inu" are registered as the viewer's favorite tags. In this case, the generation unit 23 generates a recommendation page showing information on the recommended distributor selected by the recommended distributor selection unit 251.
A broadcaster who has registered "2020 Summer Anime,""TheSea,""Yakiniku," and "Shiba Inu" as favorite tags is selected as a recommended broadcaster. The generation unit 23 generates a recommended broadcaster window showing information of the broadcaster selected as a recommended broadcaster. In this example, the area A26 displays the number of common favorite tags "4" as the degree of matching of favorite tags between the viewer and the broadcaster.
The generating unit 23 may arrange the recommended distributor windows so that a distributor with a large number of common favorite tags between the viewer and the distributor is ranked higher, or may arrange the recommended distributor windows so that a distributor who distributes video content in real time is ranked higher. The arrangement order of the recommended distributor windows may be switchable by the operation of the viewer. In addition, when the recommended distributor selecting unit 251 selects a recommended distributor according to the matching tendency of the favorite tags, the generating unit 23 may arrange the recommended distributor windows so that a distributor with a high matching tendency is ranked higher. For example, when "Shiba Inu" is a rare favorite tag with a small number of user registrations, the generating unit 23 may arrange the recommended distributor windows so that a distributor who has registered "Shiba Inu" as a favorite tag is ranked higher. In addition, when the recommended distributor selection unit 251 selects a recommended distributor from distributors currently broadcasting live, the generation unit 23 may arrange the recommended distributor windows in accordance with the elapsed time since the start of real-time distribution. In addition, the generation unit 23 may arrange the recommended distributor windows in such a way that the distributors followed by the viewer are placed at the top or bottom.

Viewers of the recommendation page can easily find users with similar hobbies and tastes based on the recommended distributor window, without having to search for users who have registered common favorite tags. This is expected to increase the frequency with which viewers watch video content from distributors with similar hobbies and tastes, and to boost interest in video content.

The generating unit 23 may periodically update the generated recommendation page and upload it onto the network. The viewer terminal 40 can access the recommendation page via the network. The viewer can browse information on recommended distributors whose hobbies and tastes match the viewer's registered favorite tags, and can select and watch video content by the recommended distributors.

Next, we will explain the operation of the video distribution device of the second embodiment.

FIG. 14 is a flowchart illustrating an example of an operation of transmitting recommended distributor information in the moving image distribution device according to the second embodiment.

As a premise for the following operation, it is assumed that the video distribution device 20 performs an operation of registering a user's favorite tags in the same manner as in the first embodiment.

The first acquisition unit 211 of the moving image distribution device 20 acquires real-time moving image data and user identification information of the distributor from the distributor terminal 10 , and transmits them to the recommended distributor selection unit 251 .

The second acquisition unit 212 acquires the viewer's user identification information from the viewer terminal 40 and transmits it to the recommended distributor selection unit 251 .

The recommendation distributor selection unit 251 uses the user identification information of the distributor to select the recommended distributor from the database 2.
The recommended distributor selection unit 251 obtains information on the distributor's favorite tag associated with the user identification information of the distributor from the database 26 using the viewer's user identification information. The recommended distributor selection unit 251 selects one or more distributors as recommended distributors based on the information on the viewer's favorite tag (step SC1).

The recommendation sending unit 252 sends information about the recommended distributor selected by the recommended distributor selecting unit 251 to the viewer terminal 40 (step SC2).
In response to a request from the generation unit 23, the recommendation distributor selection unit 251 may transmit information on the recommended distributor selected by the recommendation distributor selection unit 251 to the generation unit 23. In this case, the generation unit 23 may transmit a recommendation page generated based on the information on the recommended distributor to the viewer terminal 40.

The video distribution device 20 may periodically perform steps SC1 to SC2 while acquiring real-time video data from the distributor terminal 10. The video distribution device 20 may also perform steps SC1 to SC2 in response to a viewer's operation on the viewer terminal 40. For example, the video distribution device 20 may perform steps SC1 to SC2 when a user accesses a video distribution site, when a user logs in to a video distribution site, when a user registers as a member of the video distribution site, or when a user accesses a video distribution site.
Steps SC1 and SC2 may be performed when, for example, editing of registered information of favorite tags is requested.

As described above, according to the present embodiment, the video distribution device 20 can easily match viewers with distributors by managing user information by attaching preference tags according to hobbies and preferences to each user. Furthermore, the video distribution device 20 can provide the matching results between viewers and distributors to the viewer terminal without the need for the viewer's operation. As a result, a viewer can easily find a distributor who matches his/her hobbies and preferences, and the follow rate of the preference tag can be improved. In addition, the preference tag can be used to encourage communication between the viewer and the distributor, and the rate at which comments are posted and acquired by the viewer can be improved. In this way, the video distribution device 20 can provide a video distribution device, a video distribution method, and a video distribution program that provide a service that activates communication between the viewer and the distributor and livens up the video content.

Furthermore, according to the present embodiment, the video distribution device 20 can provide the viewer terminal with the matching result between the viewer and the distributor. Therefore, the video distribution device 20 can increase the opportunities for the viewer to view various video contents, thereby improving the transition rate or viewing frequency.

<<Modifications>>
The second embodiment may include the following modifications.
In step SC1, the recommended distributor selection unit 251 selects one or more viewers as recommended viewers based on the information of the favorite tag recorded in association with the user identification information of the distributor. A recommended viewer indicates a distributor who is recommended by the distributor based on the distributor's favorite tag. A recommended viewer includes, for example, a distributor who is recommended based on a matching state with the distributor's favorite tag. A recommended viewer includes a viewer who has registered a favorite tag that is common to the distributor's favorite tag. In this case, the recommended distributor selection unit 25
The unit 251 uses the user identification information of the viewer to obtain information on the viewer's favorite tags associated with the user identification information of the viewer from the database 26. The recommended distributor selection unit 251 uses the user identification information of the distributor to obtain information on the distributor's favorite tags associated with the user identification information of the distributor from the database 26. The recommended distributor selection unit 251 compares the information on the favorite tags associated with the viewer with the information on the favorite tags associated with the distributor, and selects one or more viewers as recommended viewers depending on the matching form of the favorite tags.

In step SC2, the recommendation sending unit 252 selects the recommendation distributor selecting unit 251
The recommendation sending unit 252 may transmit information on the recommended viewer selected by the recommended distributor selection unit 251 to the distributor terminal 10 in response to a request from the generation unit 23. In this case, the generation unit 23
may transmit a recommendation page generated based on the information of the recommended viewers to the distributor terminal 10.

According to this example, the video distribution device 20 can provide the distributor terminal with a matching result between the distributor and the viewer without requiring any operation by the distributor.
It is possible to distribute video content according to the hobbies and preferences of the viewer. As a result, it is possible to provide a video distribution device, a video distribution method, and a video distribution program that provide a service that stimulates communication between the viewer and the distributor and enhances the video content.

In step SC1, the recommended distributor selection unit 251 selects one or more viewers and distributors as matching users based on the information of the favorite tag recorded in association with the user identification information of the distributor and the information of the favorite tag recorded in association with the user identification information of the viewer. The matching users indicate viewers and distributors who are matched based on the favorite tags of the viewers and distributors. The matching users include, for example, distributors associated with favorite tags that have a high degree of agreement or tendency to match with the favorite tags of the viewers, or viewers associated with favorite tags that have a high degree of agreement or tendency to match with the favorite tags of the distributors. The matching users include users who have registered common favorite tags. In this case, the recommended distributor selection unit 251 uses the user identification information of the viewers to obtain information on the favorite tags of the viewers associated with the user identification information of the viewers from the database 26. The recommended distributor selection unit 251 uses the user identification information of the distributor to obtain information on the favorite tags of the distributor associated with the user identification information of the distributor from the database 26. The recommended distributor selection unit 251 compares information of favorite tags associated with the viewer with information of favorite tags associated with the distributor, and selects one or more viewers and distributors as matching users according to the matching form of the favorite tags.

In step SC2, the recommendation sending unit 252 selects the recommendation distributor selecting unit 251
The recommendation sending unit 252 sends information about the matching users selected by the above to at least one of the distributor terminal 10 and the viewer terminal 40 in response to a request from the generation unit 23.
Information on the recommended viewer selected by the recommended distributor selection unit 251 may be transmitted to the generation unit 23. In this case, the generation unit 23 may transmit a recommendation page generated based on the information on the recommended viewer to at least one of the distributor terminal 10 and the viewer terminal 40. The recommendation transmission unit 252 may transmit information on the matching user to an administrator terminal (not shown). The administrator terminal is a terminal used by an administrator or the like who manages the video distribution device 20. The administrator terminal may have the same configuration as the distributor terminal 10 or the viewer terminal 40.

According to this example, the video distribution device 20 can provide the matching results between the distributor and the viewer to the distributor terminal, the viewer terminal, or the administrator terminal without requiring any operation by the distributor, the viewer, or the administrator. As a result, the distributor, the viewer, or the administrator can distribute video content according to the hobbies and preferences of the distributor and the viewer. Therefore, it is possible to provide a video distribution device, a video distribution method, and a video distribution program that provide a service that stimulates communication between the viewer and the distributor and enhances the video content.

It has been explained that when candidate information for favorite tags obtained from a user terminal is included in the dictionary data, the user information management unit 25 can associate the candidate information for favorite tags with user identification information as favorite tags and record the information in the database 26, but this is not limited to this.
For example, when a word similar to or related to the acquired candidate information of a favorite tag is included in the dictionary data, the user information management unit 25 may record, for example, a word that is registered by a large number of users as a favorite tag in the database 26 as the favorite tag.
5 will be described in the case where another word "YY" which is an abbreviation or another name of the word "XXXXX" is acquired from the user terminal as candidate information for a favorite tag. In this case, it is assumed that both the word "XXXXX" and the other word "YY" which is an abbreviation or another name of the word "XXXXX" are registered in the dictionary data. The user information management unit 25 determines whether the word "YY" is related to the word "XX" in the dictionary data.
In the case where a large number of users have registered "XXX" as a favorite tag, "XXXXX" may be recorded as a favorite tag in the database 26. This makes it possible to prevent the favorite tags registered for users from varying, and to more effectively classify users according to their hobbies and preferences.

Another example will be described below in which another word "YY", which is an abbreviation or alias of the word "XXXXX", is acquired from the user terminal as candidate information for a favorite tag. In this example, it is assumed that the word "XXXXX" and another word "YY" are registered in the dictionary data. If it is registered in the dictionary data that the word "YY" is related to the word "XXXXX" and that "XXXXX" is correct as a regular expression, the user information management unit 25 will select "XX
XXX" may be recorded as a favorite tag in the database 26. According to this example, it is possible to suppress the variation in favorite tags registered for users, and to more effectively classify users according to their hobbies and preferences.

Another example will be described below in which another word "YY", which is an abbreviation or another name for the word "XXXXX", is acquired from the user terminal as candidate information for a favorite tag. In this example, it is assumed that the word "XXXXX" is registered in the dictionary data, but the other word "YY", which is an abbreviation or another name for the word "XXXXX", is not registered. The user information management unit 25:
If the word "YY" is registered in the dictionary data as a word related to the word "XXXXX," then "XXXXX" may be recorded in the database 26 as a favorite tag.
In this way, the words registered in the dictionary data and the words to be searched for in the dictionary data are correlated with each other, and the information is not the candidate information of the favorite tag requested to be registered by the user, but
Another word associated with the candidate information may be registered as a favorite tag. According to this example, it is possible to suppress the variation in favorite tags registered for users, and to more effectively classify users according to their hobbies and preferences. In addition, there is no need to register items for abbreviations or aliases in the dictionary data, and the amount of information in the dictionary data can be reduced. Furthermore, it is also possible to prevent inconsistencies in the description contents and update status in both items for the word "XXXXX" and the other word "YY".

When the user has not registered a favorite tag, the user information management unit 25 may, for example, refer to the user's viewing history or a recent registration ranking of favorite tags to recommend a favorite tag that is likely to match the user's preferences and encourage the user to register the favorite tag. In this case, it is also desirable for the user information management unit 25 to present to the user words that are registered in the dictionary of the dictionary management device 30 as recommended favorite tags. According to this example, the user information management unit 25 can encourage the user to register a favorite tag, and the recommended distributor selection unit 251 can select a recommended distributor based on the registered favorite tag. Therefore, the video distribution device 20 can provide a service that promotes communication between viewers and distributors and enhances video content.

The present invention is not limited to the above-mentioned embodiment, and can be modified in various ways without departing from the gist of the present invention. The embodiments may be combined as appropriate, and in that case, the combined effect can be obtained.
