Description

System and method for controlling access of game content purchasers to broadcast content containing game content

[0001] The present invention relates to a technology for controlling a game content purchaser's access to a spoiler broadcast of game content.

[0002] Along with the continuous development of information and communication technology, the computer game market is also continuously developing.

[0003] Meanwhile, ordinary individuals also broadcast their gameplay through platforms that provide streaming services, such as YouTube.

[0004] However, when individuals who do not have broadcasting rights to game content, such as ordinary individuals, broadcast game content, viewers who watch it may lose interest in the game content, and as a result, the desire to purchase by potential customers who originally had an intention to purchase the game content may decrease.

[0005] In order to prevent such problems, it is necessary to limit the scope of exposure, etc., for spoiler content among the game content when broadcasting game content.

[0006] However, when it comes to live broadcasting of game content, it is difficult to broadcast while considering the spoiler content areas and conditions within the game content, and even if one attempts to comply, the conditions to be complied with are complex, and problems may arise where content outside the permitted broadcast scope is accidentally broadcast due to live broadcasting.

[0007] Therefore, the accidental exposure of spoiler content during a broadcast of game content may cause a problem that lowers viewers' desire to purchase the game content.

[0008] The present invention relates to a system and method for controlling access to broadcast content containing game content for game content purchasers, for enabling differentiation in access to broadcast content between purchasers and non-purchaser regarding spoiler broadcasts of spoiler content among game content.

[0009] The access control system for a purchaser of game content containing game content according to the present invention for solving the above problem comprises: a client terminal including a game module for executing game content and a broadcasting module for executing a streaming service for broadcasting said game content; and a broadcasting platform server that receives broadcast content for broadcasting said game content from said client terminal and transmits said received broadcast content to an online viewer terminal, wherein the client terminal generates viewer-specific spoiling level information and spoiling time information corresponding to a content allowance range that can be viewed by each viewer for said game content and transmits them to the broadcasting platform server.

[0010] The above game module is characterized by requesting electronic contract information related to the game content from an electronic contract server according to broadcast status information provided by the broadcast module, and generating spoiler level information for each viewer based on the electronic contract information provided by the electronic contract server.

[0011] The broadcast module is characterized by generating broadcast status information regarding whether the game content is included in the broadcast content being broadcast and transmitting it to the game module, and generating the broadcast status information by identifying a game status code on the screen of the game content.

[0012] The broadcasting module is characterized by generating spoiling time information using the viewer-specific spoiling level information transmitted from the game module, and transmitting the generated spoiling time information together with the broadcasting content to the broadcasting platform server.

[0013] The broadcasting platform server is characterized by performing a verification process regarding whether each viewer watching the broadcasting content has purchased the game content, and determining the viewing range of the broadcasting content for the viewer based on the spoiling level information and the spoiling time information for each viewer.

[0014]

[0015] The method for controlling access of a purchaser of a game content to a broadcast content containing game content according to the present invention for solving the above problem comprises: a step in which, when the game content is executed, the client terminal generates broadcast status information regarding whether the streaming service is executed; a step in which, according to the broadcast status information, the client terminal requests electronic contract information related to the game content from an electronic contract server; a step in which, upon receiving the electronic contract information from the electronic contract server, the client terminal generates spoiling level information and spoiling time information for the game content based on information regarding the content allowance range for each broadcast viewer of the game content included in the electronic contract information, and transmits the spoiling level information and spoiling time information for each viewer together with the broadcast content to the broadcast platform server; and a step in which, upon receiving the broadcast content, the spoiling level information for each viewer, and the spoiling time information, the broadcast platform server determines the viewing range of the broadcast content for a viewer who wishes to watch the broadcast content based on the spoiling level information for each viewer and the spoiling time information.

[0016] The step of generating the broadcast status information is characterized by generating the broadcast status information through the identification of a game status code on the screen of the game content.

[0017] The step of determining the viewing range of the broadcast content is characterized by receiving game content access rights information for the viewer from the game content distribution server, and determining the viewing range of the broadcast content based on the game content access rights information and spoiling level information for each viewer.

[0018] According to the present invention, instead of a person determining the spoiler content zone and conditions for broadcast content containing game content, a license agreement defining such content is digitized, and whether the current game state or the state of the game executed immediately thereafter is spoiler content is determined in real time. In the case of spoiler content, the game software, broadcast software, and broadcast platform can easily monitor whether it is spoiler content. Furthermore, the viewing access rights and content of the broadcast content regarding the game content are differentiated for each viewer based on whether the game content has been purchased, thereby promoting the viewer's desire to purchase.

[0019] The effects obtainable from the present invention are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art to which the present invention belongs from the description below.

[0020] The following drawings attached to this specification illustrate preferred embodiments of the present invention and serve to further enhance understanding of the technical concept of the present invention along with specific details for implementing the invention; therefore, the present invention should not be interpreted as being limited only to the matters described in such drawings.

[0021] FIG. 1 is a block diagram illustrating a configuration system for a game content purchaser's access control system for broadcast content including game content according to an embodiment of the present invention.

[0022] FIG. 2 is a flowchart for explaining a method for controlling access of a game content purchaser to broadcast content including game content according to an embodiment of the present invention.

[0023] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[0024] The embodiments of the present invention are provided to more fully explain the invention to those skilled in the art, and the following embodiments may be modified in various different forms, and the scope of the invention is not limited to the following embodiments. Rather, these embodiments are provided to make the disclosure more faithful and complete and to fully convey the spirit of the invention to those skilled in the art.

[0025] The terms used herein are for describing specific embodiments and are not intended to limit the invention. As used herein, the singular form may include the plural form unless the context clearly indicates otherwise. As used herein, the term "and / or" includes any one of the listed items and all combinations of one or more thereof.

[0026]

[0027] Generally, the reason broadcasters are prohibited from broadcasting all content, especially spoiler content, through game broadcasts is that if viewers see spoiler content through such broadcasts, their interest in the game will be fully satisfied, which may reduce their desire to purchase and consequently lead to a decline in sales.

[0028] However, for broadcasters, the inability to broadcast all content and only a portion of the game within a single broadcast is a source of significant dissatisfaction and inconvenience for both viewers and broadcasters in terms of the completeness of the broadcast.

[0029] However, since allowing viewers who have already purchased the game content to access the broadcast of that game content does not cause a decline in revenue, there is no need to restrict the broadcast of the game content. In other words, viewers who cannot prove that they have purchased the game should be restricted from watching the broadcast containing spoilers, while those who can prove that they have purchased the game should be allowed to watch the broadcast containing spoilers.

[0030] Rather, additional revenue can be expected because users purchase the game in order to watch the broadcast (before the broadcast), even if they have no interest in the game itself. This is because they buy the game before even watching it, rather than deciding whether to purchase it after watching the broadcast and judging whether the game is good or not.

[0031] Furthermore, if game advertisements are displayed at the location where game content would normally appear when a section is inaccessible due to spoilers, thereby inducing viewers to purchase the game and enabling them to watch the broadcast, the immediate conversion of viewers into buyers is maximized. Since the effectiveness of the advertisement is also easy to measure, the advertising effect of the game broadcast is also easy to verify.

[0032] The above description can be applied not only to games but also to videos / broadcasts of various primary works such as movies, dramas, animations, and sports broadcasts.

[0033] Movies, dramas, animations, sports broadcasts, etc., may be available only if the right to view the relevant work has been purchased or if one is subscribed to a platform where the relevant work is registered.

[0034]

[0035] FIG. 1 is a block diagram illustrating a system for controlling access to game content purchasers to broadcast content containing game content according to one embodiment of the present invention (hereinafter referred to as the broadcast content access control system).

[0036] Referring to FIG. 1, the broadcast content access control system (10) includes a client terminal (100), an electronic contract server (200), a broadcast platform server (300), and a game content distribution server (400).

[0037] The client terminal (100) is a device belonging to a game user who runs game content and a broadcaster who runs streaming services for broadcast content.

[0038] The client terminal (100) may include a desktop PC or a mobile terminal, etc. The client terminal (100) is connected to the electronic contract server (200) and the broadcasting platform server (300) via a wired / wireless communication network. The wired communication network may include an Ethernet communication network or a serial (USB) communication network, etc., and the wireless communication network may include a wireless internet such as WiFi (wireless fidelity), a 2G to 5G mobile communication network, etc.

[0039] The client terminal (100) includes a game module (110) for executing game content and a broadcast module (120) for executing a streaming service for broadcasting game content.

[0040] The game module (110) executes game content. The game module (110) is game software executed within the client terminal (100) and is a component that generates and manages state information (game level, event, scene, etc.) that occurs during gameplay. The game module (110) includes hardware and software (not shown) for executing game content.

[0041] The game module (110) can request profile information regarding game content and electronic contract information related to the broadcasting of game content, etc. from the electronic contract server (200).

[0042] Here, the electronic contract information includes information regarding the scope of content permission for each broadcast viewer of game content provided through a content supply channel (e.g., YouTube, Spotify, Netflix, etc.) concluded between the broadcaster and the game developer, and the channel (broadcaster) identifier within the said platform.

[0043] The game module (110) can generate viewer-specific spoiler level information corresponding to the content allowance range that each viewer can view for game content based on electronic contract information provided from the electronic contract server (200), and transmit the generated viewer-specific spoiler level information to the broadcasting platform server (300) through the broadcasting module (120).

[0044] First, when the game content is executed, the game module (110) transmits a request signal to the broadcast module (120) to inquire whether a streaming service for the game content is being executed, and receives broadcast status information from the broadcast module (120) in response to the request signal.

[0045] When the game content is executed, the game module (110) transmits a signal (e.g., a discovery_request JSON message) to confirm the presence of a nearby broadcast module (120). Accordingly, when a nearby broadcast module (120) transmits a response signal (e.g., a discovery_response message), the game module (110) receives the response signal.

[0046] When the game module (110) receives a response signal from a nearby broadcast module (120), it sends a request signal to the broadcast module (120) to check the broadcast status regarding whether the streaming service is running. The request signal is a signal requesting the broadcast status and channel information of the broadcast module (120), and may correspond, for example, to a “broadcast_check_request” message. When the game module (110) receives the request signal, the broadcast module (120) may send broadcast status information to the game module (110) in response to the request signal.

[0047] Accordingly, the game module (110) receives broadcast status information transmitted from the broadcast module (120). The broadcast status information includes information regarding whether a streaming service for broadcast content is being performed, identification information of the broadcaster (contractee), or information regarding whether game content is included.

[0048] When it is confirmed from the broadcast status information provided by the broadcast module (120) that the broadcast content includes game content, the game module (110) can request electronic contract information related to the game content from the electronic contract server (200).

[0049] Accordingly, when electronic contract information is received from the electronic contract server (200), the game module (110) generates spoiler level information for each viewer of the game content based on information regarding the content allowance range for each broadcast viewer of the game content included in the electronic contract information.

[0050] Viewer-specific spoiler level information is information intended to restrict viewing rights for broadcast content by distinguishing between viewers who have purchased game content and viewers who have not purchased game content. For example, viewer-specific spoiler level information is information that distinguishes the viewing scope of the broadcast of game content based on whether the game content has been purchased, and if purchased, whether the game content series has been purchased, and whether additional game content has been purchased.

[0051] Additionally, the game module (110) can perform spoiler marking to prevent spoiler in the spoiler section corresponding to the viewer-specific spoiler level information for the game content.

[0052] The game module (110) transmits viewer-specific spoiler level information for the game content to the broadcast module (120).

[0053] The broadcast module (120) performs a streaming service for broadcast content. In particular, the broadcast module (120) performs a broadcast service for broadcast content that includes game content. The broadcast module (120) is executed within the client terminal (100).

[0054] First, when the broadcast module (120) receives a request signal from the game module (110) to inquire whether a streaming service containing game content is running, it generates broadcast status information corresponding to the request signal and transmits the generated broadcast status information to the game module (110).

[0055] When the broadcast module (120) receives a request signal from the game module (110), it can transmit broadcast status information, including the plugin version, current broadcast status, and broadcast channel ID, to the game module (110) in the form of a “broadcast_check_response” message.

[0056] The broadcast module (120) can check whether the broadcast content being broadcast includes a status code for game content through a watermark or an explicit small code displayed on the game screen, and transmits information regarding whether the broadcast content includes game content to the game module (110) as broadcast status information.

[0057] After that, when the broadcast module (120) receives viewer-specific spoiling level information for game content from the game module (110), it generates spoiling time information corresponding to the viewer-specific spoiling level information.

[0058] To this end, the broadcasting module (120) can register a game ID for the game used in the video / broadcast in advance before starting a pre-recorded game video or a real-time game broadcast, and can register game advertising information such as an address for purchasing the game, a QR code, or an affiliator code for each game. The affiliator code corresponds to an identification ID for the advertiser, serves as a discount code, and also has the function of notifying the seller and copyright holder of which person's advertisement was used to make the purchase.

[0059] The broadcast module (120) generates spoiling time information as information about the spoiling section of the game content that has been spoiled.

[0060] Spoiling time information is information indicating a time interval corresponding to a spoiling level for each viewer among the content of game content included in the broadcast content. That is, the broadcast module (120) generates information regarding which spoiling level for each viewer corresponds to the content of the game content currently being executed, and when the corresponding time is.

[0061] The broadcast module (120) transmits the broadcast content for the game content received from the game module (110), along with viewer-specific spoiling level information and spoiling time information, to the broadcast platform server (300). At this time, the broadcast module (120) can transmit game advertisement information for the game content to the broadcast platform server (300) along with the broadcast content, viewer-specific spoiling level information, and spoiling time information.

[0062] The electronic contract server (200) includes a Personal Data Store (PDS) and stores and manages electronic contract information that cannot be disclosed, including trade secrets and personal information.

[0063] The electronic contract server (200) is a platform for concluding and managing electronic contracts between a broadcaster and a game developer. It can perform settlement functions.

[0064] The electronic contract server (200) stores profile information for game content, along with guideline information regarding the viewing scope for each viewer of the game content broadcast as electronic contract information. For example, the electronic contract information includes information regarding the content allowance scope for each viewer of the game content broadcast provided through a content supply channel concluded between a broadcaster and a game developer.

[0065] The broadcasting platform server (300) corresponds to a platform that delivers broadcasting content transmitted from a client terminal (100) to a viewer, and has established infrastructure for this purpose. Such a broadcasting platform server (300) may include a server of a provider that services the aforementioned content supply channels (platforms), such as YouTube, Spotify, and Netflix.

[0066] The broadcasting platform server (300) receives broadcasting content for broadcasting containing game content from a client terminal (100) and transmits the received broadcasting content to an online viewer terminal.

[0067] The broadcasting platform server (300) performs a verification process regarding whether each viewer watching the broadcasting content has purchased the game content, and determines the viewing range of the broadcasting content for the viewer based on the spoiling level information and spoiling time information for each viewer.

[0068] The broadcasting platform server (300) determines whether the broadcasting content is a game content section allowed in the spoiling level information based on the spoiling time information and transmits the broadcasting content to the viewer's terminal.

[0069] When the broadcast content reaches a section marked with a spoiler mark, that is, a section corresponding to spoiler time information, the broadcast platform server (300) checks the access rights to the game content based on game profile information, such as whether the viewer has purchased the game content, subscribed to a pass containing the game content, or experienced specific events or content within the game content.

[0070] To this end, authentication for linkage is required in advance between the broadcasting platform server (300) and the game content distribution server (400) to exchange access rights information for game content for each viewer.

[0071] The broadcasting platform server (300) transmits an inquiry signal regarding access rights to game content, such as whether a viewer who intends to watch broadcast content containing game content is a purchaser of game content, to the game content distribution server (400). At this time, the broadcasting platform server (300) transmits identification information (e.g., game profile ID, etc.) regarding the viewer who intends to watch broadcast content to the game content distribution server (400) along with the inquiry signal.

[0072] After that, the broadcasting platform server (300) receives information from the game content distribution server (400) regarding whether the viewer corresponding to the identification information is a purchaser of the game content, that is, information on access rights to the game content.

[0073] Based on the game content access rights information and viewer-specific spoiling level information provided by the game content distribution server (400), the broadcast platform server (300) provides the broadcast content of the corresponding section only to viewers who have access rights to the game content, and transmits only limited broadcast content to viewers who do not.

[0074] Based on the received game content access rights information and viewer-specific spoiling level information, the broadcast platform server determines the viewing range of the broadcast content by providing the broadcast content of the corresponding section only to viewers who have access rights to the game content, and transmitting only limited broadcast content to viewers who do not. Additionally, the broadcast platform server (300) may decide to provide alternative content, such as game advertisement information, to viewers who do not have access rights in a limited manner.

[0075] After that, the broadcasting platform server (300) may not show any game content to the viewer according to spoiling time information corresponding to the viewing range of the determined broadcast content, or may transmit only limited broadcast content such as game broadcast information prepared by the broadcaster, game advertisement information, images, videos, or the broadcaster's voice.

[0076] When the game content distribution server (400) receives an inquiry signal from the broadcast platform server (300) regarding whether the viewer is a purchaser of the game content, it verifies the identification information of the viewer who intends to watch the broadcast content, and extracts information regarding the content access rights for the game being broadcast, i.e., game content access rights information, based on game profile information, such as whether the viewer corresponding to the identification information is a purchaser or a regular subscriber of the game content. After that, the game content distribution server (400) transmits the game content access rights information for the viewer to the broadcast platform server (300).

[0077]

[0078] FIG. 2 is a flowchart for explaining a method for controlling access of a game content purchaser to broadcast content including game content according to an embodiment of the present invention.

[0079] The access control method for a purchaser of game content according to the present invention is performed by a client terminal that executes game content and a streaming service for broadcasting said game content, and by a broadcasting platform server that transmits said received broadcast content to an online viewer terminal.

[0080] First, when game content is executed, the client terminal generates broadcast status information regarding whether the streaming service is executed (step S1000).

[0081] When game content is executed, the game module of the client terminal transmits a signal to check for the presence of nearby broadcast modules. Accordingly, upon receiving a response signal transmitted from a nearby broadcast module, the game module transmits a query signal to that broadcast module to verify the broadcast status regarding whether the streaming service is running.

[0082] Upon receiving an inquiry signal from the game module, the broadcast module can generate broadcast status information corresponding to the inquiry signal and transmit it to the game module. The broadcast module can generate broadcast status information by identifying a game status code displayed on the screen of the game content. Such broadcast status information includes information regarding whether a streaming service for the broadcast content is being performed, identification information of the broadcaster (contractee), or information regarding whether game content is included.

[0083] After step S1000, according to the broadcast status information, the client terminal requests electronic contract information related to the game content from the electronic contract server (step S1100).

[0084] If it is confirmed from the generated broadcast status information that the broadcast content includes game content, the client terminal can request electronic contract information related to the game content from the electronic contract server. The client terminal can request electronic contract information along with profile information for the game content from the electronic contract server.

[0085] The electronic contract information includes information regarding the scope of content permission for each broadcast viewer of game content provided through the content supply channel concluded between the broadcaster and the game developer, and the channel (broadcaster) identifier within the relevant platform.

[0086] Accordingly, the client terminal receives electronic contract information from the electronic contract server.

[0087] After step S1100, upon receiving electronic contract information from the electronic contract server, the client terminal generates viewer-specific spoiling level information and spoiling time information for the game content based on information regarding the content permission range for each broadcast viewer of the game content included in the electronic contract information, and transmits the viewer-specific spoiling level information and spoiling time information together with the broadcast content to the broadcast platform server (step S1200).

[0088] When electronic contract information is received from the electronic contract server, the client terminal generates viewer-specific spoiler level information that distinguishes the viewing range of the game content broadcast based on, for example, whether the game content has been purchased, whether the game content has been purchased by series if purchased, whether additional game content has been purchased, etc.

[0089] In addition, the client terminal can perform spoiler marking to prevent spoiler in spoiler sections corresponding to viewer-specific spoiler level information for game content.

[0090] After step S1200, when the broadcast content, viewer-specific spoiling level information, and spoiling time information are received, the broadcast platform server performs a verification process regarding the access rights to the game content, such as whether the game content has been purchased for each viewer watching the broadcast content, and determines the viewing range of the broadcast content for the viewer based on the viewer-specific spoiling level information and spoiling time information (step S1300).

[0091] When the broadcast platform server receives broadcast content, spoiler level information and spoiler time information for each viewer, it requests information regarding whether the viewer corresponding to the identification information is a purchaser of the game content, that is, game content access rights information, from the game content distribution server. After that, the broadcast platform server receives the game content access rights information from the game content distribution server.

[0092] Based on the received game content access rights information and viewer-specific spoiler level information, the broadcasting platform server determines the viewing scope of the broadcast content by providing the relevant section of broadcast content only to viewers who have access rights to the game content, and transmitting only limited broadcast content to viewers who do not. Additionally, the broadcasting platform server may decide to provide alternative content, such as game advertisement information, on a limited basis to viewers who do not have access rights.

[0093] After that, the broadcasting platform server may not show the game content to the viewer at all, or may transmit only limited broadcasting content such as game broadcasting information, game advertising information, images, videos, or the broadcaster's voice, according to spoiling time information corresponding to the viewing range of the determined broadcast content.

[0094]

[0095] Although the invention has been described above with reference to embodiments, this is merely illustrative and does not limit the invention. Those skilled in the art will understand that various modifications and applications not exemplified above are possible within the scope of the essential characteristics of the embodiments. For example, each component specifically shown in the embodiments may be modified and implemented.
