Description

The present invention relates to a program, an information processing device, and an information processing method.

Conventionally, there is known technology that distributes video of an event in which multiple players participate to user terminal devices, increases the prize money for the event in accordance with contributions (so-called tips) made by each user in relation to the video, and distributes the increased prize money to the participating players (see Patent Document 1). This technology can increase the motivation of players participating in the event.

Japanese Patent Application Laid-Open No. 2021-144628

In the above-mentioned prior art, the act of providing video footage of an event brings benefits to the player, but the user only receives a merit award for having performed that act. For this reason, there is room for improvement in improving user motivation when it comes to actions that bring benefits to players related to videos of content such as events.

This disclosure provides a program, information processing device, and computer system that can increase users' motivation to engage in actions that bring benefits to players of content videos.

The first aspect is a program that causes a computer to function as: request accepting means for accepting a request from a viewer of a video distributed during a first period, the video being content in which multiple players participate, to purchase a medium of value related to the video during a second period based on the first period; first associating means for associating the medium of value with the viewer in response to the request; and second associating means for disassociating the viewer from the medium of value during a third period after the second period has elapsed, and associating the disassociated medium of value with a user different from the viewer.

Furthermore, in the first aspect, there are multiple viewers requesting purchases, and multiple value media can be generated according to the number of purchase requests from each of the multiple viewers.

Furthermore, in the first aspect, the value medium includes identification information that can uniquely identify each of the multiple value media and is issued in accordance with the number of purchase requests, and the first associating means can associate the value medium with each of the multiple viewers in accordance with payment by each of the multiple viewers of the purchase price for the value medium after the second period has elapsed.

Furthermore, in the first aspect, the value medium includes identification information that can uniquely identify each of the multiple value media and is issued according to the number of purchase requests, and the computer can function as a first granting means that grants a first benefit based on the identification information to each of the multiple viewers who purchase the value medium.

Furthermore, in the first aspect, the first granting means can grant the first benefit after the second period has elapsed in accordance with payment by each of the multiple viewers of the purchase price for the value-storing medium.

Furthermore, in the first aspect, the identification information can be assigned to the value medium based on the status of the content at the time a request to purchase the value medium is received.

Furthermore, in the first aspect, the first granting means can grant the first benefit to each of the multiple viewers based on the status of the content at the time the request to purchase the value medium is accepted.

Furthermore, in the first aspect, the computer is caused to function as a second granting means that grants a second benefit to a viewer based on a combination of multiple value media associated with the viewer, the content being each of multiple game parts played during a first period, and the second granting means can grant the second benefit further based on information that integrates the results of each of the multiple game parts.

In addition, in the first aspect, the computer functions as a setting acceptance means that accepts from a viewer the setting of a first purchase condition related to content for purchasing a medium of value regardless of a purchase request, and the first association means can associate the medium of value with the viewer when the status of the content satisfies the first purchase condition.

Furthermore, in the first aspect, the computer functions as a setting acceptance means for accepting from the viewer second purchase conditions for purchasing the value medium regardless of a purchase request, the second purchase conditions relating to purchases by other viewers, and the first association means can associate the value medium with the viewer when the number of purchase requests by other viewers satisfies the second purchase conditions.

FIG. 2 is a sequence diagram showing a series of operations of the platform system in this embodiment.

A platform system 1 according to an embodiment of the present disclosure (hereinafter also referred to as the "present embodiment") will be described with reference to the drawings.

<Explanation of the platform system>
The platform system 1 is one aspect of a computer system, and is a system for distributing videos of content (hereinafter simply referred to as "content") in which multiple players participate. The platform system 1 also provides a platform for generating, selling, and distributing value media (hereinafter simply referred to as "value media") related to the videos of this content. The value media related to the videos of the content may be defined by digital data (in other words, may be represented by digital data), such as a non-fungible token (hereinafter also referred to as "NFT"). In this embodiment, an example in which the value media is an NFT will be described. Furthermore, as a value media according to this embodiment, an NFT-ized digital trading card (hereinafter simply referred to as "card") will be referred to as an "NFT trading card" hereinafter.

For example, there may be multiple videos of content and/or audio corresponding to the videos of content for a single piece of content. For example, if the content is a competitive game, there may be multiple videos of the content, such as a main video that captures the entire competitive game and videos that focus on each of the multiple players competing. There may also be multiple audio, such as a main audio and a secondary audio.

For example, multiple value media are generated. The value media may include identification information (hereinafter also referred to as "medium identification information") for uniquely identifying each of the multiple value media. With this configuration, each of the multiple value media generated can be uniquely identified, and it can be proven that each is an irreplaceable, one-of-a-kind entity.

The medium identification information may be, for example, a series of numbers (so-called serial numbers) assigned to multiple value media.

Media identification information may be issued, for example, according to the number of purchase requests from each of multiple viewers.

The medium identification information may be assigned to the medium of value based on the status of the content at the time a request to purchase the medium of value is received, for example. The status of the content may be determined to be popular or not based on the amount of comments on the content. The amount of comments may include, for example, the number of comments on each play or each player, the presence or number of enthusiastic comments, and the amount of consumable media (tips) given to each player. The amount of comments may also be determined based on, for example, a history of comments from viewers posted on the content within a specified period. For example, if the status of the content at the time a purchase request is received is determined to be popular, a more valuable serial number may be assigned to the medium of value as the medium identification information.

In platform system 1, primary distribution allows companies that operate platform system 1, game operating companies, or distributors (e.g., retailers) to sell NFTs, such as NFT trading cards, online. Hereinafter, the environment for realizing primary distribution in platform system 1 (e.g., the operating environment for hardware, software, etc.) will also be referred to as the "first platform." Furthermore, in platform system 1, sold NFTs can be bought and sold in transactions between users, which will be secondary distribution. Hereinafter, the environment for realizing secondary distribution in platform system 1 will also be referred to as the "second platform."

The content according to this embodiment is, for example, a competitive game played by multiple players, a so-called e-sports game. However, the content according to this embodiment is not intended to be limited to this. For example, the content according to this embodiment may be a real sports match or live event that takes place in real space.

As shown in FIG. 1, the platform system 1 is composed of a server device 2, a distribution device 3, and multiple user devices 5. In the platform system 1, the server device 2 and the multiple user devices 5 are connected to each other so that they can communicate with each other via a communication network 6.

The server device 2 is an information processing device used by a vendor selling NFT trading cards (hereinafter also referred to as the "vendor"). By executing a predetermined program, the server device 2 realizes functions such as managing an EC server for selling NFTs to users and managing NFT transactions between users. For simplicity's sake, this embodiment describes an example in which the vendor is also the operator (hereinafter also referred to as the "system operator") that operates the platform system 1.

The distribution device 3 is an information processing device used by a person who distributes video content (hereinafter also referred to as the "distributor"). The distribution device 3 executes a predetermined program to output video content, such as game footage from an e-sports league, to a user device 5. The distribution device 3 also generates a value medium related to the video content. For simplicity's sake, this embodiment will describe an example in which the distributor is also the operator of the e-sports league.

User device 5 is an information processing device used by users, such as viewers of content videos. User device 5 may be a general-purpose terminal device such as a smartphone or laptop, or a device dedicated to platform system 1. User device 5 provides users with a user interface for trading value media by executing a predetermined program. The predetermined program may be, for example, an application program dedicated to platform system 1 (hereinafter also referred to as a "distribution app"), or a general-purpose web browser provided on information processing devices. User device 5 receives (specifically, downloads and installs) the distribution app from server device 2 or an application store, for example, via communication network 6. The distribution app may, for example, have a wallet function for storing and managing NFTs owned by the user.

In platform system 1, each user is assigned account information including user identification information and a password for account authentication. This account information is sent from user device 5 to server device 2 when logging in from a distribution app or web browser, and account authentication processing is performed on server device 2. After account authentication, mutual communication between server device 2 and user device 5 becomes possible. After logging in, user device 5 receives data necessary for trading NFT trading cards from server device 2, and outputs images and sounds of the NFT trading cards to the display and speakers based on user operation.

<NFT trading card purchase process>
Now, with reference to FIG. 2, an example of a process for purchasing an NFT trading card in the platform system 1 will be described.

As shown in Figure 2, in platform system 1, viewers can purchase NFT trading cards associated with images (including at least one of still images and moving images; the same applies below) of each game in the e-sports league.

(1) During the first match of the e-sports league, viewers can request to purchase NFT trading cards for that match from user devices 5 while watching the first match. (2) Server device 2 accepts the request to purchase NFT trading cards for the first match from user devices 5. (3) During the second match, viewers can also request to purchase NFT trading cards for that match from user devices 5 while watching the second match. (4) Server device 2 accepts this purchase request from user devices 5.

The period during which videos of content such as each match in the e-sports league are distributed is also referred to as the "first period." The distribution format of videos during the first period may include archived distribution in addition to live distribution. Furthermore, the period during which requests to purchase valuable items such as NFT trading cards for each match are accepted is also referred to as the "second period." The second period may be the same as the first period or a different period. For example, the second period may start when the distribution of each match's video begins and end when the distribution of each match's video ends. As another example, the second period may end when the e-sports league ends for each match, or when the e-sports league award ceremony ends if the match is a final. Note that during the second period, the NFT trading card does not necessarily have to be associated with the requesting viewer until a purchase request for the NFT trading card is accepted. For example, the NFT trading card may be associated with the requesting viewer after the second period has elapsed in response to payment of the purchase price for the NFT trading card.

(5) When the e-sports league ends, the server device 2 causes the distribution device 3 to generate NFT trading cards for each match in the e-sports league for which purchase requests were accepted (in other words, to issue NFT trading cards). In other words, the server device 2 causes the distribution device to generate as many NFT trading cards as there are purchase requests for each match. (6) The server device 2 associates the requested NFT trading cards with the viewer for whom a purchase request was accepted (in other words, grants the NFT trading cards).

(7) Viewers who purchase NFT trading cards can list these NFT trading cards on the NFT e-commerce market (hereinafter also referred to as the "NFT Marketplace") from their user device 5. For example, another user who wishes to purchase an NFT trading card can select the listed NFT trading card displayed on the NFT Marketplace screen and issue a purchase instruction. Then, in response to this purchase instruction, the association between the viewer and the NFT trading card is released, and the NFT trading card is associated with this other user (in other words, the NFT trading card is transferred from the viewer to the other user).

The NFT marketplace is what is known as a secondary distribution market (resale market). In the NFT marketplace, for example, the digital data to be traded may be limited to NFTs only. In other words, in the NFT marketplace, the data to be traded may be limited to data for which the authenticity of the data and the authenticity of the data owner are ensured to a certain extent. The marketplace is realized, for example, by a website or distribution app provided by the server device 2.

With the above configuration, platform system 1 allows viewers to request the purchase of NFT trading cards related to the video of an e-sports league match, with revenues distributed to players, during the video broadcast. This allows viewers to support players in ways other than watching the match and posting comments about the match. Furthermore, even after the match ends, viewers can keep the NFT trading cards as part of their collection or earn revenue by selling them to other users. This increases players' motivation to participate in the content, while also increasing users' motivation to engage in actions that benefit players related to the content video. Furthermore, by limiting the period during which requests to purchase NFT trading cards for each match are accepted to within a second period, the number of NFT trading cards available for sale can be limited, ensuring their scarcity.

When a medium of value is traded between users, the price of that medium of value is determined by consensus between the users, and so the price can fluctuate. For this reason, if the primary distribution period, during which sellers accept requests from viewers to purchase the medium of value, overlaps with the secondary distribution period, during which the medium of value can be traded between users, including viewers, there is a concern that if the price of the medium of value rises in the secondary distribution period, it could lead to hoarding in the primary distribution period, hindering the stable supply of the medium of value. With the above configuration, platform system 1 can separate these periods, ensuring a stable supply of the medium of value in the primary distribution period.

<Distribution of revenue from NFT trading cards>
Now, with reference to FIG. 3, an example of a method for distributing profits from NFT trading cards in the platform system 1 in the example of FIG. 2 will be described.

As shown in FIG. 3, in platform system 1, revenues from the NFT trading cards of the Nth match (N: natural number) in which Player A and Player B compete in the e-sports league are distributed to parties involved in the e-sports league. The amount for distributing revenues generated from the purchase of value media such as NFT trading cards is also referred to as the "first distribution amount." For example, suppose that 10,000 NFT trading cards are issued for the Nth match, each costing 100 yen. In this case, 5% of the revenues, or 50,000 yen, may be determined as the first distribution amount and distributed to each of the multiple players (specifically, Player A and Player B) who competed in the Nth match. Alternatively, 30% of the revenues, or 300,000 yen, may be determined as the first distribution amount and distributed to the distributor as a sales commission for the NFT trading cards. 50% of the revenues, or 500,000 yen, may be determined as the first distribution amount and distributed to the distributor of the content images and the operator of the e-sports league. Additionally, 10% of the revenue, or 100,000 yen, may be determined as the first distribution amount and distributed to the eSports league prize pool.

With the above configuration, revenue from NFT trading cards can be distributed among multiple players, thereby increasing players' motivation to participate in the content.

<NFT trading card body and card parts>
In the platform system 1, an NFT trading card may be composed of a plurality of NFTs, such as a card body, card parts, etc. An example of the card body and card parts that make up an NFT trading card will now be described with reference to Fig. 4 .

As shown in Figure 4, viewers and other users can purchase the card body C1 that makes up the NFT trading card while the content video is being streamed, and can also purchase card parts P from an online shop operated by a retailer. This online shop is one of the online shop services provided by the first platform.

In the first platform, a consideration (hereinafter also referred to as the "first purchase consideration") is set for each of the first NFT defining the card body C1 and the second NFT defining the card parts P to associate the first NFT and the second NFT with a user. The second NFT is a different type of NFT from the first NFT and may, for example, be one that can be used in association with the first NFT. The first purchase consideration is the consideration paid by a consumer user to purchase an NFT from a seller or the like in an online shop, i.e., the consideration for a B2C transaction. In addition, the first purchase consideration for the card body C1 is distributed as a first distribution amount and a second distribution amount to parties other than the user, such as a system operator, game operator, retailer, player, video related parties, and/or audio related parties.

Specifically, on the first platform, a user selects the NFTs they wish to purchase from those displayed on the screen of a website (e.g., a video distribution site or an e-commerce site) or the official shop of a distribution app provided by the server device 2, requests a purchase, and associates the purchased NFT with the user in response to this purchase request (in other words, grants the NFT). Furthermore, when purchasing an NFT from this online shop, the user pays a first purchase consideration to a retailer or the like that sells the NFT at the online shop.

Card body C1 is the base and main body of an NFT trading card. Card body C1 can be used alone to form an NFT trading card. The data that defines card body C1 is NFT.

Card parts P are components that make up an NFT trading card. The data that defines card parts P is also NFT. Card parts P include, for example, a frame P1 (referred to as "card frame" in FIG. 4) that decorates the frame of the NFT trading card, a signature part P2 (referred to as "player signature" in FIG. 4) that shows the signature of a player such as an e-sports athlete displayed on the NFT trading card, and a sticker part P3 (referred to as "sticker" in FIG. 4) that shows a sticker of the team mark of the e-sports athlete or a sticker of a game character. The signature part P2 and sticker part P3 can be freely positioned in various locations on the image of the NFT trading card. In other words, card parts P are game media that can customize the card body C1. Furthermore, the issuer of the NFT information for signature part P2 may indicate, for example, the player who signed the signature.

In the platform system 1, for example, a user may purchase a first NFT of the card body C1 and a second NFT of the frame P1, and be given a second NFT of the signature part P2 as a first benefit, as described below.

In the platform system 1, a user can associate the first NFT of a purchased card body C1 with the second NFT of a similarly purchased frame P1 and the second NFT of an attached signature part P2. By associating them in this way, the user can decorate (so-called decorate) the card body C1 with the frame P1 and the signature part P2. In other words, the user can combine the frame P1 and the signature part P2 with the card body C1.

With the above configuration, platform system 1 allows users to associate multiple NFTs with each other, allowing them to freely change the state of the NFT trading card itself based on the frame, signature parts, etc. The value of an NFT trading card can change depending on its state, so when changing the state of an NFT trading card, users can have fun by being creative and inventive in increasing its value or exploring popular designs.

<Configuration of Server Device>
Continuing the explanation, returning to Fig. 1, the hardware configuration and functional configuration of the server device 2 will be explained below.

The server device 2 has a network interface 21, a memory unit 22, and a control unit 23. The network interface 21 and the memory unit 22 are electrically connected to the control unit 23 via a bus 29.

The network interface 21 is communicatively connected to each user device 5 via a communication network 6 such as the Internet or a LAN.

The storage unit 22 is a device that stores programs and data, such as a main storage device, auxiliary storage device, or external storage device. The storage unit 22 is composed of, for example, a hard disk drive (HDD), random access memory (RAM), read-only memory (ROM), and solid state drive (SSD). The storage unit 22 stores various programs, including some of the programs according to this embodiment, as well as various data such as a user DB 221 and a token DB 222.

The program according to this embodiment can be stored on a storage medium. The storage medium storing the program may be a non-transitory computer-readable medium. There are no particular limitations on the non-transitory storage medium, and it may be, for example, a USB memory stick, a CD-ROM, or other storage medium.

User DB221 stores, for each user identification information of a user playing a game, information such as medium identification information (e.g., NFT type and/or serial number for each type) that identifies the value medium held by the user, the balance of electronic value that can be used within platform system 1, and attribute information that indicates the user's attributes. Hereinafter, this information will be collectively referred to as "user information." Here, "electronic value" may be, for example, digital currency (e.g., electronic money or crypto assets).

Token DB 222 stores, for each medium identification information of an NFT circulating on platform system 1, parameters, release date and time (issue date and time), seller (issuer), total number issued, current holder, transaction history (in other words, holder history), and other information in association with each other. This information may be included in the corresponding NFT (specifically, the digital data defining the NFT). Furthermore, the transaction history may include, for example, the seller, buyer, and transaction date and time for each transaction. Furthermore, the serial number is a unique number assigned to each NFT issued for the same type of NFT. The NFT type and serial number, or the serial number, is one aspect of medium identification information. For example, in the example of Figure 2 above, the NFT type may distinguish each game. Furthermore, in the case of unsold NFTs, token DB 222 may store the unique digital data itself associated with each NFT, i.e., each serial number. An NFT may contain at least one of two digital certificates: one that certifies its authenticity and one that certifies its current owner. When sold to a user, the NFT may be moved (sent) to the user device 5 and deleted from the trading card DB 222. Hereinafter, this information will be collectively referred to as "NFT information."

"Parameters" refers to, for example, the combat power, attack power, defense power, stamina (HP), intelligence, skill level, skill type, rank, or rarity of a medium such as an NFT trading card.

The control unit 23 is a processing device (e.g., a processor) that is composed of a microcomputer including a CPU and semiconductor memory and controls the operation of the device 2 itself, i.e., performs data calculations, processing, and transfers, executes programs, and controls other devices. The control unit 23 can realize various functions of the server device 2 by executing programs stored in the memory unit 22.

By executing various programs, the control unit 23 functions as an information processing means 231, a matching means 232, a receiving means 233, a generation control means 234, a determination means 235, an identification means 236, an association means 237, and an assignment means 238.

-Information processing means-
The information processing means 231 transmits and receives various data to and from each user device 5. Examples of the main data received by the information processing means 231 include requests for output information, various requests in response to user operations (e.g., requests to purchase value media), user information, and NFT information (including the NFT itself). Examples of the main data transmitted by the information processing means 231 include distribution apps and NFT information. The information processing means 231 may also generate output information for causing the user device 5 to output NFT trading cards, for example, via a website or distribution app.

The information processing means 231 may, for example, execute processing for payment settlement of the purchase price of the value medium based on a request for the purchase of the value medium accepted by the request accepting means 2331. The processing for payment settlement of the purchase price may, for example, be executed using a payment method designated by the user. Possible payment methods include card payment, carrier payment, electronic money payment, or bank transfer payment. For example, if the payment method designated by the user is credit card payment, the information processing means 231 may, as processing for payment settlement of the purchase price, send a credit card payment instruction to the credit card company's system, including the purchase price, payee information, and credit card information.

- Verification method -
The verification means 232 uses the user identification information received from the user device 5 to authenticate the user account.

-Method of reception-
The receiving means 233 receives various selections, instructions, requests, etc. from the user. The receiving means 233 receives an instruction from the viewer to transfer the value medium to another user, or an instruction from a user other than the viewer to purchase the value medium.

-Means of accepting requests-
The accepting unit 233 may include a request accepting unit 2331. The request accepting unit 2331 accepts a request from a viewer of a video of content in which multiple players participate to purchase a medium of value related to the video. For example, as described in the example of FIG. 2 above, if the content is an event such as a game match, the medium of value related to the video may be an NFT trading card associated with an image of the game distributed at the event. Furthermore, the content video may be a video distributed during a first period, and the request accepting unit 2331 may accept a request to purchase a medium of value related to the video during a second period based on the first period. If the content is an e-sports league match, the first period may be the period during which the match video is being live-streamed, i.e., during the match, and the second period may be the period from the start of the match to the end of the e-sports league. As another example, the first period and the second period may be the same period.

-Selection acceptance method-
The accepting unit 233 may include a selection accepting unit 2332. The selection accepting unit 2332 accepts from the viewer a selection of a video or audio to be viewed from at least one of a plurality of videos and a plurality of audios in the content.

-Method of accepting settings-
The accepting unit 233 may include a setting accepting unit 2333. The setting accepting unit 2333 accepts the setting of a first purchase condition related to content from a viewer. The first purchase condition is a condition for purchasing a value medium regardless of a purchase request from the viewer. In other words, the first purchase condition is a condition for automatically purchasing a value medium depending on the content.

The setting receiving means 2333 receives, for example, from a viewer, the setting of second purchase conditions regarding purchases by other viewers. The second purchase conditions are conditions for purchasing a medium of value regardless of a purchase request from the viewer himself/herself. In other words, the second purchase conditions are conditions for automatically purchasing a medium of value in response to a purchase request from another viewer.

-Generation control means-
The generation control means 234 instructs the distribution device 3 to generate a value medium in response to a purchase request received by the request receiving means 2331. The generation control means 234 may acquire the generated value medium from the distribution device 3 in response to this instruction. The generation control means 234 may provide the acquired value medium to the user device 5 of the viewer who made the request. As another example, the value medium generated by the distribution device 3 may be provided directly from the distribution device 3 to the user device 5 of the viewer who made the request. The generation control means 234 may, for example, instruct to generate a number of value mediums equal to the total number of purchase requests and the number to be assigned to one or more players. Furthermore, the generation control means 234 may, for example, instruct to assign medium identification information to the generated value medium. If the medium identification information is a serial number, the number to be assigned to each value medium may be determined randomly or in the order in which the purchase requests are received.

There may be multiple viewers requesting the purchase of value media. In this case, the generation control means 234 may cause the distribution device 3 to generate multiple value media in accordance with the number of purchase requests from each of the multiple viewers. The generation control means 234 may, for example, cause the distribution device 3 to generate the same number of value media as the number of purchase requests. With this configuration, it is possible to generate the same number of value media as the number of purchase requests. This prevents viewers who wish to support a player by purchasing value media from being unable to purchase them because the number prepared in advance has sold out, i.e., they can avoid a situation where they want to support a player by purchasing an NFT trading card but are unable to do so. This makes it possible to provide a platform system 1 that provides a high level of satisfaction to viewers.

-Decision-making method-
The determining means 235 determines a first distribution amount for distributing the profits generated from the purchase of the value medium to each of one or more players among the plurality of players in response to the purchase request received by the request receiving means 2331. For example, as in the example of FIG. 3 above, the determining means 235 may determine the first distribution amount as 50,000 yen each to Player A and Player B who competed in the Nth match. With this configuration, the profits generated from the purchase of the value medium can be distributed to players participating in the content. This can increase players' motivation to participate in the content.

The determination means 235 may, for example, determine at least one of the first distribution amount and the quantity of media of value to be granted to players who participated in the content based on the degree of contribution identified by the contribution level identification means 2362. For example, if player A's degree of contribution in the Nth game is identified as "high" and player B's degree of contribution is identified as "low," the determination means 235 may adjust the distribution rate of the revenue from the Nth game's NFT trading cards to 7% for player A and 3% for player B, and determine the first distribution amount to be 70,000 yen for player A and 30,000 yen for player B. Furthermore, for example, if player A's degree of contribution in the Nth game is identified as "high" and player B's degree of contribution is identified as "low," the determination means 235 may determine the number of NFT trading cards to be granted to player A in the Nth game to be 10, and the number of NFT trading cards to be granted to player B to be 5.

The determination means 235 may, for example, determine the identification information of a medium of value to be associated with each of one or more players based on the level of contribution identified by the contribution level identification means 2362. For example, when the serial numbers of NFT trading cards range from #1 to #100, the determination means 235 may determine that the serial number of the NFT trading card to be associated with a player identified as having a contribution level of "A" is the lowest number, i.e., the most valuable number, #1. With this configuration, the identification information of a medium of value to be associated with a player can be determined based on the player's level of contribution to the video. This can motivate players to participate in content with the goal of obtaining a medium of value with better identification information.

The determination means 235 may, for example, determine a distribution amount (hereinafter also referred to as a "second distribution amount") to distribute revenue to video personnel involved in filming the video selected by the viewer or audio personnel involved in recording the selected audio, other than the multiple players. Video personnel involved in filming the video of the content (hereinafter also simply referred to as "video personnel") may include, for example, the cameraman who filmed the video selected by the viewer and/or the video editor who edited the video. Furthermore, audio personnel involved in recording the audio of the content (hereinafter also simply referred to as "audio personnel") may include, for example, the narrator who was responsible for the audio selected by the viewer and/or the audio editor who edited the audio. This configuration can increase the motivation of content personnel other than players to provide better video or audio to viewers.

- Specific means -
The identification unit 236 identifies various parameters. For example, the identification unit 236 may identify the status of the content when the purchase request was received. For example, the identification unit 236 may identify the status of the content based on one or more comment histories when the purchase request was received. For example, the identification unit 236 may identify the status of the content as "popular" if the amount of comments when the purchase request was received exceeds a threshold.

-Means of identifying value-
The identification means 236 may include, for example, a value identification means 2361. The value identification means 2361 identifies the value of the medium identification information of each of the multiple value media. The value identification means 2361 may, for example, identify the value of each serial number (one aspect of the medium identification information) of the multiple generated NFT trading cards. A method for identifying the value of the medium identification information may, for example, be registered in advance in the storage unit 22. For example, if the medium identification information is a series of numbers #1 to #100, the value identification means 2361 may sort this series of numbers in ascending order, with lower numbers having higher values. In other words, the value identification means 2361 may assign #1 to the number with the highest value, and assign numbers with decreasing values until #100 is the number with the lowest value.

-Means for identifying contribution level-
The identification unit 236 may include, for example, a contribution level identification unit 2362. The contribution level identification unit 2362 identifies a contribution level (hereinafter simply referred to as a "contribution level") indicating the degree of contribution of each of a plurality of players to the video of the content.

The contribution level determination means 2362 may, for example, determine the degree of popularity of the content at the time the purchase request was accepted (hereinafter also referred to as "excitement level") as the contribution level.

The contribution level determination means 2362 may, for example, determine the level of excitement for each of one or more scenes (e.g., a predetermined unit frame period) included in the video of the content based on the amount of comments made by viewers on the video of the content. For example, the contribution level determination means 2362 first calculates the amount of comments made on the content based on the comment history. This amount of comments may include, for example, the number of comments made on each play, the presence or absence of highly enthusiastic comments or the number of such comments, and the amount of consumable media (e.g., tips) given to each player. Next, the contribution level determination means 2362 may determine the level of excitement for each of the multiple players who participated in the content (e.g., on a three-level scale: "high," "medium," or "low") based on these calculated amounts.

The contribution level determination means 2362 may determine the excitement level based on the situation of the content, in addition to the viewer's reaction to the video of the content. For example, if the content is a game, the contribution level determination means 2362 may determine an increased excitement level for a scene in which a big move is executed in a battle, or a scene in which the player character's parameters (HP, etc.) fluctuate greatly. On the other hand, the contribution level determination means 2362 may determine a decreased excitement level for a scene in which the competing player characters observe each other from a distance. Furthermore, the excitement level may be determined based on the viewer's reaction at a venue where a real-life event is held, in addition to the viewer's reaction to the game's distributed video. For example, the contribution level determination means 2362 may determine the excitement level based on the volume, volume, and content of the viewers' cheers.

- Association method -
The associating means 237 associates the user with the NFT in response to a purchase request from the user accepted by the request accepting means 2331 .

The associating means 237 associates the value medium with the viewer in response to the viewer's payment of the purchase price for the value medium. When making this association, the associating means 237 may perform processing to settle the price for this association (the first purchase price for the value medium) using a payment method designated by the viewer (for example, debit from a bank account or payment by electronic value). When the processing to settle this payment is completed, the associating means 237 may associate the value medium with the viewer who made the payment.

With the above configuration, viewers can purchase a medium of value that is related to the video content, and the revenue from that medium is distributed to players. Furthermore, even after the video distribution ends and the viewer purchases the medium of value, the viewer can use the medium of value for a variety of purposes, such as keeping the medium in their own collection or selling it to other users to earn revenue. This increases players' motivation to participate in the content, while also increasing users' motivation to take actions that benefit players.

The associating means 237 may, for example, associate one or more of the multiple media of value with at least one of the multiple players participating in the content. The associating means 237 may, for example, associate an NFT trading card generated for the Nth match to be associated with the winning player with the winning player of the Nth match.

With the above configuration, by participating in content, players can acquire value media related to the content's video, such as NFT trading cards from matches. For example, players can sell these acquired value media on a second platform, which is a secondary distribution market. Furthermore, if the value media is NFT, the player's name will be shown to the seller as part of the NFT information transaction history, which may result in higher value than if the item were listed by an ordinary user. This provides players with a new source of revenue, further increasing their motivation to participate in the content.

The associating means 237 may, for example, associate a medium of value having a higher value of medium identification information than the medium of value associated with the viewer with one or more of the multiple players.

With the above configuration, by participating in content, players can acquire valuable media such as NFT trading cards that contain medium identification information, such as highly rare serial numbers. Furthermore, players can acquire valuable media that are more valuable than those associated with viewers. Furthermore, players can sell these acquired valuable media, which are given serial numbers or other attributes that are more valuable than those sold by viewers, on the second platform, which is a secondary distribution market.

The associating means 237 may associate a medium of value with one or more players, for example, by designating at least one of the lower numbers in the series of numbers assigned to the medium of value and the truncated number as high-value numbers. The truncated number is a round number, and may be, for example, at least one of the following: a repeated number, a number with one or more consecutive zeros, a number that is a power of 10, a consecutive number, a palindrome, or a number that is a pun. For example, if the value identification means 2361 identifies the lower numbers among the serial numbers #1 to #100 assigned to the medium of value as high-value, the associating means 237 may associate NFT trading cards assigned serial numbers #1 and #2 with players A and B who competed in the match. The associating means 237 may also associate the remaining #3 to #100 with viewers whose purchase requests were accepted. This configuration allows players to associate medium of value assigned with medium identification information of lower numbers or truncated numbers, which are generally more likely to be premium numbers. This allows players to own premium value media and sell them to other users on the second platform.

The associating means 237 may, for example, associate the number of value media determined by the determining means 235 with the player. With this configuration, the player can acquire the number of value media determined according to the player's level of contribution to each video. This can increase the player's motivation to participate in the content.

-First association means-
The associating means 237 may include a first associating means 2371. The first associating means 2371 associates a value medium with a viewer during the second period. The first associating means 2371 may associate a value medium with the viewer in response to a request from the viewer received by the request receiving means 2331, for example.

The first associating means 2371 may, for example, associate a value medium with a viewer if the content satisfies a first purchase condition. The content may, for example, indicate whether a specific player will participate.

The first associating means 2371 may associate a value medium with a viewer, for example, when the content situation satisfies a first purchase condition. For example, if the content is a game part and the first purchase condition is "one of multiple players performing a great move," the first associating means 2371 may associate a value medium with a viewer when one of the players performs a great move in the game part. As another example, if the first purchase condition is "the excitement level is 'high'," the first associating means 2371 may associate a value medium with a viewer when the amount of comments exceeds a threshold and the excitement level of the content is identified as "high." With this configuration, a viewer can automatically purchase a value medium when the content situation satisfies the first purchase condition. Even if a viewer is so engrossed in watching the content video or posting comments of support that they forget to request the purchase of the value medium, i.e., forget to buy it, they can still purchase the value medium for the content video in a situation that satisfies the condition.

For example, the first associating means 2371 may associate the value medium with a viewer when the number of purchase requests for the value medium from other viewers satisfies a second purchase condition. If the second purchase condition includes a condition that "the number of purchase requests from other viewers is 100 or more," the first associating means 2371 may count the number of purchase requests for the Nth game by other viewers, and associate the Nth game's NFT trading card with the viewer when the number of purchase requests reaches 100. With this configuration, a viewer can automatically purchase the value medium when the number of purchase requests from other viewers satisfies the second purchase condition. Even if a viewer is so engrossed in watching content videos or posting comments of support that they forget to make a purchase request for the value medium, i.e., forget to buy it, they can still purchase the value medium if the number of purchase requests for the value medium from other viewers, i.e., the number of purchase orders, satisfies the condition.

- Second association means -
The associating means 237 may include second associating means 2372. During a third period after the second period has elapsed, the second associating means 2372 disassociates the viewer from the value medium in response to an instruction from the viewer or a user different from the viewer, and associates the disassociated value medium with the different user. In other words, the second associating means 2372 transfers the value medium from the viewer to the different user. This configuration allows the second period of primary distribution and the third period of secondary distribution to be separated. Therefore, trading (resale) of the value medium between users during the second period of primary distribution can be prevented. Therefore, while the price of the value medium is determined by consensus among users and thus the price may fluctuate, the same value medium can be prevented from being sold by a seller.

- Means of granting -
The granting means 238 grants benefits to users such as viewers.

-First providing means-
The granting unit 238 includes a first granting unit 2381. The first granting unit 2381 grants a first benefit based on the medium identification information to each of a plurality of viewers who purchase a medium of value. This first benefit may be, for example, a card part P for decorating an NFT trading card or an effect to be applied to the NFT trading card. For example, if the issued serial number is #1, the first granting unit 2381 may grant the first benefit by referencing the association between the number #1 and the first benefit. As another example, the first granting unit 2381 may draw the first benefit using a lottery table associated with the serial number #1, which is used to draw the first benefit. This configuration can motivate viewers to obtain better medium identification information in order to obtain a better first benefit.

The first granting means 2381 may grant the first benefit after the second period has elapsed, in response to the payment by each of the multiple viewers of the purchase price for the value medium. If the first benefit were granted within the second period, the content of the first benefit could have an impact, causing a sudden increase or decrease in purchase requests. With this configuration, the first benefit is granted after the second period during which purchase requests are accepted has elapsed, thereby avoiding the risk of such an impact.

The first granting means 2381 may grant a first benefit to each of a plurality of viewers, for example, based on the status of the content at the time a request to purchase the value medium is received. If the content status is determined to be "exciting," the first granting means 2381 may grant a first benefit that is rarer or more valuable than standard to the viewer whose purchase request was received at that time. With this configuration, viewers can be made to request the purchase of the value medium when the content status is in a better state, i.e., when the content is exciting. This makes it possible to further boost excitement for the content by viewers requesting the purchase of the value medium.

- Second providing means -
The granting means 238 includes a second granting means 2382. The second granting means 2382 grants a second benefit to the viewer based on a combination of multiple value media associated with the viewer. For example, if the value media is an NFT trading card, the second benefit may be a card part P that decorates the NFT trading card. Furthermore, if the combination of multiple value media is a combination of value media related to a video of content in which a specific player participated, the second benefit may be a signature part P of the specific player. As another example, if the combination of multiple value media is a combination of value media related to a video of content in which a specific player participated, the second benefit may be a video associated with the NFT trading card that includes historical data of the specific player's operation inputs. In the latter case, for example, if the content is a competitive game, not only may a video of the competitive game be output as an NFT trading card, but historical data of the specific player's operation inputs in the competitive game may also be output as the second benefit. With this configuration, the NFT trading card also outputs historical data on operational inputs that cannot be obtained by hard capture of the screen, further increasing its rarity.

If the content is each of multiple game parts played during the first period, the second granting means 2382 may grant the second benefit based on, for example, information that integrates the results of each of the multiple game parts. For example, if the game parts are each match in an e-sports league and the multiple NFT trading cards purchased by the viewer are NFT trading cards for videos of all matches in which player A participated, and player A won all of the matches, the second granting means 2382 may grant the second benefit as a benefit for player A, the winner, completing all of the matches. With this configuration, the second benefit is granted based on the results of each of the multiple game parts, allowing the viewer to request the purchase of a medium of value while taking into account the progress of the multiple game parts. This can increase the interest in requesting the purchase of a medium of value.

<Examples of screens and screen transitions>
5, an example of screens and screen transitions related to video distribution of content in the platform system 1 will be described. In this example, the content is Game G, which is one of the tournament matches in an e-sports league.

As shown in FIG. 5, the distribution device 3 distributing the video of Game G outputs a viewing screen 810 to the viewer's user device 5. The viewing screen 810 includes a video display area 811, a video switching operation area 812, an audio switching operation area 813, a purchase request button 814 (labeled "Purchase Support NFT" in FIG. 5), an automatic purchase setting screen button 815, and a chat section 816 that displays chat messages posted in response to the video of Game G.

The video display area 811 is an area that displays video of the e-sports match G. The video switching operation area 812 is an area for switching the video displayed in the video display area 811. The video switching operation area 812 includes a main camera button 812a for switching to the main camera, a player A button 812b for switching to a camera that focuses on player A, and a player B button 812c for switching to a camera that focuses on player B.

For example, by default, the distribution device 3 displays the video captured by the main camera in the video display area 811. When a viewer presses the Player A button 812b, the viewing screen 810 switches the video displayed in the video display area 811 from the video captured by the default main camera to the video captured by the camera focused on Player A, i.e., the video centered on Player A. Similarly, when a viewer presses the Player B button 812c, the video displayed in the video display area 811 switches to the video captured by the camera focused on Player B, i.e., the video centered on Player B.

For example, if a request to purchase NFT trading cards for match G is received from a viewer while video centered on player A is displayed in video display area 811, determination means 235 may determine the first distribution amount in response to this request so that the amount to be distributed to player A is greater than the amount to be distributed to player B. Specifically, determination means 235 may determine the first distribution amount by setting player A's distribution rate at 7% and player B's distribution rate at 3%. Conversely, if a request to purchase NFT trading cards for match G is received from a viewer while video centered on player B is displayed, determination means 235 may determine the first distribution amount by setting player B's distribution rate at 7% and player A's distribution rate at 3%, for example.

For example, if a request to purchase an NFT trading card for match G is received from a viewer while video centered on player A is being displayed in video display area 811, the determination means 235 may, in response to this request, determine a second distribution amount so that the profits from the NFT trading card are also distributed to the cameraman who shot the video centered on player A.

The audio switching operation area 813 is an area for switching the audio to be output along with the video of match G. The audio switching operation area 813 includes a main audio button 813a for outputting the main audio including the game audio, commentator C's audio, and commentator D's audio, a commentator audio button 813b for outputting the secondary audio of commentator C, and a commentator audio button 813c for outputting the secondary audio of commentator D.

For example, by default, the distribution device 3 outputs the main audio along with the video of match G. When the user presses the commentator audio button 813b, the viewing screen 810 switches the audio output along with the live video of the match from the main audio to the secondary audio of commentator C.

For example, if a request to purchase an NFT trading card for match G is received from a viewer while a secondary audio track for commentator C is being output, the determination means 235 may determine the second distribution amount in response to this request so that the profits from the NFT trading card are also distributed to commentator C.

When a viewer presses the purchase request button 814, the user device 5 sends a request to purchase an NFT trading card for Match G to the server device 2. When the request acceptance means 2331 of the server device 2 accepts this purchase request, after the end of Match G, the NFT trading card for Match G is associated with the viewer who made the request (in other words, the NFT trading card is granted) in response to the viewer's payment of the purchase price for the NFT trading card.

The automatic purchase settings screen button 815 is a button for displaying the automatic purchase settings screen 820. When the viewer presses the automatic purchase settings screen button 815, the user device 5 displays the automatic purchase settings screen 820.

The automatic purchase settings screen 820 is a screen for setting the first and second purchase conditions. The automatic purchase settings screen 820 includes a game status setting area 821, a sales status setting area 822, and a player setting area 823.

The game status setting area 821 is an area for setting first purchase conditions related to the game status. The game status setting area 821 displays check boxes for setting first purchase conditions, such as (a) a specific round (e.g., semi-finals or later), (b) the level of chat excitement displayed in the chat box 816 being "medium" (indicated as "Chat excitement" in FIG. 5), and (c) a specific technique being used (indicated as "Showplay included" in FIG. 5). When a viewer specifies the conditions they wish to adopt in these check boxes and presses the OK button 824, the user device 5 generates specified condition information indicating the specified first purchase conditions and transmits it to the server device 2. The setting acceptance means 2333 of the server device 2 receives the specified condition information from the user device 5 and accepts the setting of the first purchase conditions related to the content.

The sales status setting area 822 is an area for setting second purchase conditions related to the sales status of NFT trading cards. The sales status setting area 822 displays check boxes for setting second purchase conditions, such as the number of purchase requests from other viewers being within a specified range (shown as "greater than or equal to XX and less than or equal to XX" in FIG. 5). The upper and lower limits of this specified range may be implemented so that they can be adjusted by the viewer using a drop-down list, for example. When the viewer specifies a check box and presses the OK button 824, the user device 5 generates specified condition information indicating the specified second purchase condition and transmits it to the server device 2. The setting acceptance means 2333 of the server device 2 receives the specified condition information from the user device 5 and accepts the setting of the second purchase condition related to purchases by other viewers.

The player setting area 823 is an area for setting first purchase conditions related to the player. The sales status setting area 822 displays check boxes for setting first purchase conditions, such as content in which a specific player, such as Player A or Player B, participates. When a viewer specifies the player to be used in these check boxes and presses the OK button 824, the user device 5 generates specified condition information indicating the specified second purchase conditions and transmits it to the server device 2. The setting acceptance means 2333 of the server device 2 receives the specified condition information from the user device 5 and accepts the setting of the first purchase conditions related to the content.

<Operational flow of the platform system>
An example of transaction processing in each of primary and secondary distribution in the platform system 1 will be described with reference to FIGS.

Figure 6(a) is a sequence diagram showing the process flow and interactions during the first and second periods, from when the video of the content is output until a request to purchase a medium of value as primary distribution is received from the first user, who is the viewer. Figure 6(b) is a sequence diagram showing the process flow and interactions after the second period has elapsed, from when the medium of value is generated and the purchase price is paid until the medium of value is associated with the first user. In this example, the first and second periods are the same period.

As shown in Figure 6(a), during the first and second periods, the server device 2, the first user device 5a, and the distribution device 3 perform processing within the area indicated by the combined fragment opt1 (Option1).

Specifically, first, the distribution device 3 generates output information for outputting a video of content in which multiple players participate, in order to distribute the video to the first user device 5a of the first user who is viewing the content (step st11). Next, the distribution device 3 transmits the generated output information to the first user device 5a (step st12). Next, the first user device 5a outputs the video of the content to the first user based on the output information (step st13).

The first user device 5a then receives a request from the first user to purchase a value medium related to the video of the content being output (step st14). The first user device 5a then transmits this request to the server device 2 (step st15). The request receiving means 2331 of the server device 2 then receives the request to purchase the value medium (step st17). The first user device 5a also transmits this request to the distribution device 3 (step st16). The distribution device 3 then receives the request to purchase the value medium (step st18). As another example, the first user device 5a may transmit a request to purchase the value medium to the distribution device 3, and the request receiving means 2331 of the server device 2 may then receive the request via the distribution device 3.

As shown in Figure 6(b), after the second period has elapsed, the server device 2, the first user device 5a, and the distribution device 3 execute processing within the area indicated by the combined fragment opt2 (Option2).

Specifically, first, the distribution device 3 counts the number of received requests to purchase value media (step st21). Next, the distribution device 3 generates multiple value media equal to the number of counted purchase requests, and assigns medium identification information to each of the multiple generated value media to uniquely identify it (step st22). Next, the distribution device 3 transmits the generated value media to the server device 2 (step st23).

Then, the information processing means 231 of the server device 2 executes processing for payment settlement of the purchase price of the value medium based on the received request for the purchase of the value medium (step st24). Next, in response to this purchase request, the determination means 235 of the server device 2 determines a first distribution amount for distributing the revenue generated by the purchase of the value medium to each of one or more players among the multiple players who participated in the content (step st25).

Next, the first associating means 2371 of the server device 2 associates the value medium with the first user in response to the purchase request and payment of the purchase price of the value medium (step st26). The first associating means 2371 of the server device 2 transmits the associated value medium to the first user device 5a via the network interface 21 (step st27). The first user device 5a receives the value medium from the server device 2 and stores it in the wallet function of the distribution app (step st28).

Figure 7 is a sequence diagram showing the process flow and interactions from when a second value medium is listed by a first user as a secondary distribution item until it is purchased by a second user.

As shown in Figure 7, during the third period after the second period has elapsed, the server device 2, the first user device 5a, and the second user device 5b perform processing within the area indicated by the combined fragment opt3 (Option 3).

Specifically, first, the first user device 5a receives a request from the first user to list the associated value medium on the NFT marketplace for resale (hereinafter also referred to as the "listing request") (step st31). Next, the first user device 5a transmits this listing request and the value medium to be listed to the server device 2 (step st32).

Next, the request receiving means 2331 of the server device 2 receives the listing request for the value medium and acquires the value medium to be listed (step st33). Based on this listing request, the information processing means 231 of the server device 2 generates output information for displaying the listing of the value medium on the NFT marketplace (step st34). The information processing means 231 transmits the generated output information to each user device 5 (step st35). Based on the received output information, each user device 5 displays the listing of the value medium on the NFT marketplace via a website or distribution app (step st36).

The second user device 5b then receives a request from the second user to associate the displayed value medium with the second user in order to purchase the value medium from the first user (step st38). The second user device 5b then transmits this request to the server device 2 (step st37). The request receiving means 2331 of the server device 2 then receives this request from the second user device 5b (step st39). The second associating means 2372 of the server device 2 then disassociates the value medium from the first user based on this request (step st40). The second associating means 2372 of the server device 2 then transmits the value medium acquired from the first user device 5a to the second user device 5b (step st42). The second user device 5b receives the value medium from the server device 2 and stores it in the wallet function of the distribution app (step st43).

To summarize the above, the control unit 23 (computer) of the server device 2 functions as: request receiving means (2331) for receiving a request from a viewer of a video distributed during a first period and having content in which multiple players participate, to purchase a medium of value related to the video, during a second period based on the first period; first associating means (2371) for associating the medium of value with the viewer in response to the request; and second associating means (2372) for releasing the association between the viewer and the medium of value and associating the released medium of value with a user different from the viewer during a third period after the second period has elapsed.

<Effects>
According to this embodiment, viewers can purchase a value medium related to a video of content, and after the video distribution ends and they have purchased the content, they can use the value medium for various purposes, such as keeping the value medium or selling it to other users to earn profits. This increases players' motivation to participate in the content and also increases users' motivation to take actions that bring benefits to players.

[Variations]
Although the present invention has been described based on the above embodiment, the present invention is not limited to the above embodiment. The following cases are also included in the present invention.

[First Modification]
In the above embodiment, an example was described in which the content was a game, but the content according to the present invention is not limited to this. For example, the content may be a live event by an artist or idol. In this case, the multiple players participating in the content may be artists or idols. Furthermore, if the content is a live event, the medium of value associated with the video of the content may be an NFT trading card associated with an image from the live performance. If the content is a live event by an idol group, there may be multiple videos of the live event, such as a main video capturing the entire group and videos capturing each member of the group.

[Second Modification]
In the above embodiment, an example was described in which the value medium was a digital card such as an NFT trading card, but the value medium according to the present invention is not limited to this. The value medium may be, for example, any digital data related to the video of the content. For example, if the content is a live event, the value medium may be a fungible live cut image of a specific artist who participated in the live event.

[Third Modification]
In the above embodiment, an example has been described in which the device that distributes the content video and generates the value medium is the distribution device 3, but the entity that distributes the content video and generates the value medium according to the present invention is not limited to this. For example, a seller may also serve as a distributor, and the server device 2 may distribute the content video to the user device 5 and generate the value medium. In this case, the control unit 23 of the server device 2 may include a distribution means and a generation means.

The distribution means distributes the video of the content to the user device 5. Specifically, the distribution means generates output information for outputting the video of the content on the user device 5, and transmits the generated output information to the user device 5 via the network interface 21. The output information may be, for example, information for outputting the viewing screen 810 and automatic purchase setting screen 820 described in the example of Figure 5 above.

The generating means generates value media in response to purchase requests received by the request receiving means 2331. The generating means may, for example, generate a number of value media equal to the total number of purchase requests and the number to be granted to one or more players. The generating means may also, for example, assign medium identification information to the generated value media. If the medium identification information is a serial number, the number to be assigned to each value media may be determined randomly, or may be determined in the order in which the purchase requests are received.

There may be multiple viewers requesting the purchase of value media. In this case, the generation means may generate multiple value media in accordance with the number of purchase requests from each of the multiple viewers, or may have a third-party system generate multiple value media. With this configuration, it is possible to generate as many value media as there are purchase requests. This prevents viewers who wish to support a player by purchasing value media from being unable to purchase them because the number prepared in advance has sold out, i.e., unable to support the player. This makes it possible to provide a platform system 1 that provides a high level of satisfaction to viewers.

[Fourth Modification]
Although not shown in the above embodiment, the second period may be extended depending on the status of viewers' purchases of the value medium. Specifically, the request accepting means 2331 counts the number of requests for the purchase of the value medium received per unit period. For example, the number of requests for the purchase of the value medium received per minute may be counted. If the number of counted requests exceeds a threshold, the request accepting means 2331 may extend the second period (e.g., by an additional minute) and accept requests for the purchase of the value medium. With this configuration, the second period, which is the period for accepting purchase requests, can be extended in consideration of the status of the purchase of the value medium. This allows for more flexible primary distribution.

[Fifth Modification]
Although not shown in the above embodiment, the content of the benefits granted to viewers and the manner in which the medium identification information to be assigned to the value medium is issued may be changed depending on the manner in which the content video is distributed (for example, whether it is live distribution or archive distribution).

In platform system 1, for example, the serial numbers assigned to NFT trading cards may be different for requests to purchase NFT trading cards received during the live streaming period of a content video and requests to purchase NFT trading cards received during the archive streaming period. During the live streaming period, only serial numbers such as #1, #2, etc. may be assigned, while during the archive streaming period, a combination of a single alphabet character and a serial number such as #M1, M2, etc. may be assigned.

In the platform system 1, for example, the second granting means 2382 may not grant the second benefit to the viewer based on a combination of multiple value media associated with a purchase request received during the archive distribution period. For example, purchasing an NFT trading card during the archive distribution period does not support the player participating in the content while they are playing, as would be the case in a live distribution, and therefore contributes relatively little to livening up the content. Furthermore, during the archive distribution period, there is a possibility that NFT trading cards that were sold in primary distribution during the live distribution period may already be circulating in secondary distribution. With this configuration, by changing the content of the benefit and the manner in which the medium identification information is issued between the live distribution and the archive distribution, the degree of contribution to the content can be appropriately evaluated and the circulation of value media of the same value in primary and secondary distribution can be avoided.

[Sixth Modification]
Although not shown in the above embodiment, the request accepting unit 2331 of the server device 2 may accept a request from a viewer via the user device 5 to cancel a previously accepted request for the purchase of a value medium (hereinafter also referred to as a "purchase cancellation"). The request accepting unit 2331 may also accept a purchase cancellation request within a fourth period. The fourth period is a period during which a purchase cancellation request can be accepted, and may be, for example, a period based on the first period. For example, if the first period is the period from the start to the end of each game in the e-sports league, the fourth period may be the period from the start of each game to the end of the semi-finals of the e-sports league. As another example, if the first period is the period from the start to the end of each game in the e-sports league, the fourth period may be the period until a predetermined time has elapsed after the end of each game (for example, up to one hour after the end of the game). This configuration can limit the time during which cancellations can be made, and can prevent, for example, a situation in which a viewer makes a large purchase request and then cancels all requests except for requests to purchase value media that are likely to become more valuable as the game progresses.

[Seventh Modification]
Although not shown in the above embodiment, distributed ledger technology (e.g., blockchain technology) may be utilized in transactions between users of the second platform of the platform system 1. For example, in the second platform, in order to decentralize and manage transaction information on the user (edge) side, the transaction information may be decentralized and stored in each of multiple user devices 5, including the first user device 5a and the second user device 5b. With this configuration, transaction information indicating transactions between users can be decentralized to the user devices 5 and shared between users, thereby preventing tampering with the transaction information.

In the second platform, for example, the value of an NFT, i.e., the consideration for transferring an NFT between users, may be set based on consensus among multiple users participating in the network of platform system 1, rather than just the users who conduct the transaction to transfer the NFT (in the above example, the first and second users).

Other Embodiments
The various control means and processing procedures described in the above embodiments are merely examples and are not intended to limit the scope of the present invention, its applications, or its uses. The various control means and processing procedures can be appropriately modified in design within the scope that does not change the gist of the present invention.

Games may include action games, shooting games, role-playing games, simulation games, board games, and puzzle games, and can be applied to a variety of games.

In the above embodiment, an example was given of a case in which the server device 2 and multiple user devices 5 function as a single unit to make the program work, but this is not limited to this. All of the means of the program, i.e., the reception means, generation control means, determination means, identification means, association means, and assignment means, may be provided in the server device 2 alone, the user device 5 alone, a communication terminal separate from the server device and user device 5, or two of these devices combined (e.g., distributed processing between the server device 2 and the user device 5). Furthermore, when the server device, user devices, and communication terminals function as a single unit, it is also possible to change which means function in which device as appropriate.

Even when these other embodiments are adopted, the effects of this embodiment will be achieved. It is also possible to combine this embodiment with other embodiments, and other embodiments with each other, as appropriate.
