Referring to
The broadcasting station server 30 may provide various broadcast content such as dramas, movies, commercial films (CFs), advertisements, documentaries, public videos, interviews, discussion content, and news or articles. For example, the broadcasting station server 30 may include a terrestrial broadcasting station that broadcasts the broadcast content through a terrestrial broadcasting system. Alternatively, the broadcasting station server 30 may be a cable broadcasting station that broadcasts the broadcast content through a cable broadcasting system. Alternatively, the broadcasting station server 30 may be an Internet protocol (IP) broadcasting station that provides the broadcast content through an IP network. Alternatively, the broadcasting station server 30 may be a public TV network that provides the broadcast content using sky waves.
Meanwhile, the NFT market server 20 may be a server that provides an NFT marketplace. The NFT Marketplace is a virtual space in which NFTs for digital products may be sold or purchased, and may refer to an e-commerce space in which digital products generated by artists or multiple individual sellers may be uploaded to be sold, and the uploaded digital products may be purchased by multiple purchasers.
Here, the digital products may mean all products that may be produced, distributed, consumed, and even stored in a digital form, e.g., images such as still images or moving images, sound such as music or sound of natural or artificial objects, etc. each playable on an electronic device.
Here, such digital products may be sold or purchased using the NFTs. An NFT stands for non-fungible token, which means ‘an irreplaceable token’ and may refer to a token that represents a digital asset with scarcity. An NFT certifies ownership of a digital product and verifies that ownership of the digital product is uniquely held by a person who owns the NFT. That is, the NFT means a token that verifies an owner of a digital asset.
The NFT may be configured such that a data block in which information regarding ownership and sale history is stored based on a blockchain is distributively stored in a plurality of terminals constituting a blockchain network through the blockchain network. Thus, counterfeiting, falsification, etc., may be prevented, and an original issuer may be confirmed at any time. However, unlike a cryptocurrency generally using a blockchain, since NFTs have a separate and unique recognition value, the NFTs cannot be exchanged with each other and are irreplaceable. Due to an irreplaceable and unique recognition value, the NFTs may provide a virtual asset with values of scarcity and uniqueness. The NFTs are used to sell or purchase digital products that may be generated using a digitalization method, such as an image, sound, a game item, etc.
Meanwhile, according to a request by the TV platform 10, the NFT market server 20 may transmit information related to digital products with respect to at least one piece of broadcast content to the TV platform 10. Here, the digital product-related information provided by the NFT market server 20 may be data for generating a database including identification information corresponding to at least one digital product and address information of a web page in which an NFT for the at least one digital product corresponding to the identification information may be purchased. Therefore, the TV platform 10 may generate a database including identification information corresponding to at least one digital product and web page address information corresponding to each of the identification information, based on data received from the NFT market server 20.
Here, a plurality of pieces of identification information may correspond to one digital product. In this case, the TV platform 10 may generate a database including the plurality of pieces of identification information corresponding to the one digital product.
Meanwhile, the at least one digital product may be a digital product related to broadcast content currently being played on the TV platform 10. That is, when broadcast content is played, the TV platform 10 may request the NFT market server 20 for digital product-related data regarding the played broadcast content. In response to the request by the platform 10, the NFT market server 20 may further transmit data regarding the at least one digital product. Then, the TV platform 10 may add the further transmitted data to a pre-generated database to update the pre-generated database. Conversely, the TV platform 10 may delete at least some data from an existing database based on data received from the NFT market server 20. Alternatively, an existing database may be deleted and a new database including only newly received data may be generated.
As an example, the TV platform 10 may delete, from an existing database, data that does not match newly received data. Then, the existing database may be updated by adding the newly received data to the existing database. To update a database, the NFT market server 20 may provide database version information together with transmitted data, and only different data according to respective versions may be transmitted as update data for updating the database. In this case, when a pre-generated database is present, the TV platform 10 may transmit version information of the pre-generated database to the NFT market server 20 and update the pre-generated database by receiving only update data according to the version information.
Meanwhile, the TV platform 10 may include a plurality of databases. For example, the databases may include a plurality of different databases according to types of broadcast content (e.g., a genre), a channel of the broadcast content, or time at which the broadcast content is played. To do so, the TV platform 10 may request the NFT market server 20 for data for generating different databases for respective types or channels of different pieces of broadcast content or time at which the different pieces of broadcast content are played, and the NFT market server 20 may provide the data according to the requesting.
Meanwhile, when a purchase request for an NFT for a specific digital product is received from the TV platform 10, the NFT market server 20 may proceed with an NFT transaction of the specific digital product according to the purchase request. Then, when the NFT transaction is completed, NFT status information of the specific digital product after being sold may be updated based on the NFT transaction included in the purchase request. To do so, the NFT market server 20 may transmit, to a blockchain network, transaction information for updating NFT information of the specific digital product for which the transaction has been completed, and update an NFT status of the specific digital product based on the transaction information. Then, information about the updated NFT status of the specific digital product may be received from the blockchain network, and the received NFT status information may be transmitted to the TV platform 10.
Accordingly, a user of the TV platform 10 may check a specific digital product of an NFT purchased by the user based on received NFT status information, and play the digital product through the TV platform 10 or sell the NFT for the purchased digital product through the NFT market server 20.
Meanwhile, the TV platform 10 according to an embodiment of the present disclosure may receive and play broadcast content provided by the broadcasting station server 30. A user may play broadcast content provided by the broadcasting station server 30 corresponding to a channel selected through the TV platform 10. In this case, when the user changes the channel, the TV platform 10 may receive broadcast content from another broadcasting station server according to the changed channel. That is, different broadcast content from different broadcasting station servers may be received and played depending on selection of a channel by the user. In addition, when broadcast content is received and played as described above, the TV platform 10 may request the NFT market server 20 for data for generating a database related to at least one digital product with respect to the broadcast content received and being played currently.
Meanwhile, when broadcast content received from the broadcasting station server 30 according to a selected channel is played, the TV platform 10 may analyze a scene (a broadcast scene) of the played broadcast content. Here, the broadcast scene refers to a particular broadcast content scene, i.e., a scene, and may mean a broadcast screen currently being broadcast on the TV platform 10. In addition, the TV platform 10 may analyze the broadcast scene by detecting information related to people, objects, places, terrain, or the like included in the broadcast scene.
Additionally, the TV platform 10 may determine whether a digital product related to the broadcast scene currently being broadcast is present, based on information detected from the analyzed broadcast scene and a database constituted by data received from the NFT market server 20. For example, the TV platform 10 may match the information detected from the analyzed broadcast scene with digital product identification information in the database. Then, as a result of the matching, when digital product identification information corresponding to the information detected from the broadcast scene is present, the TV platform 10 may determine that a digital product related to the broadcast scene currently being broadcast is present, and display the presence of the related digital product through a preset graphic object.
Here, the graphic object may be a graphic object displayed, for a limited time according to a preset condition, on a part of a display area in which broadcast content is played. Then, the displaying may be ended after the limited time elapses. That is, the graphic object may be a drop-type graphic object displayed only for a designated time. In this case, considering that transaction of a digital product is performed by using an NFT as described above, based on an NFT indicating a digital product and a method of displaying a graphic object (a drop type), hereinafter, the graphic object displayed for a limited time according to output of a broadcast scene is referred to as an NFT drop object.
When NFT drop objects are displayed, the respective NFT drop objects may be configured differently depending on corresponding digital products so that a user may identify digital products for the displayed NFT drop objects. Particularly, as described above, an NFT drop object of a digital product corresponding to a result of analyzing a broadcast scene may include identification information of the digital product that matches the NFT drop object so that a user may identify which element of the result of analyzing the broadcasting scene matches the corresponding digital product.
Meanwhile, as described above, NFT drop objects may correspond to digital products related to broadcast content currently being played, respectively. Thus, the NFT drop objects may be generated by manufacturers of the respective digital products and provided together with the digital products. Therefore, when data of at least one digital product (e.g.: data including identification information of the at least one digital product and address information about a web page in which an NFT for the at least one digital product may be purchased) is transmitted upon request by the TV platform 10, the NFT market server 20 may further transmit an NFT drop object respectively corresponding to the at least one digital product. That is, digital product-related data provided by the NFT market server 20 upon request by the TV platform 10 may be data including identification information corresponding to at least one digital product, address information of a web page in which an NFT for the at least one digital product may be purchased, and an NFT drop object corresponding to the at least one digital product. In addition, a database generated by the TV platform 10 based on digital product-related data provided by the NFT market server 20 is referred to as a NFT drop database (DB).
Meanwhile, when the NFT drop object is displayed, the TV platform 10 may detect whether the displayed NFT drop object is selected by a user. Then, based on a result of the detection, a purchase request for purchasing an NFT for a digital product corresponding to the NFT drop object may be transmitted to the NFT market server 20. To do so, the TV platform 10 may access a web page corresponding to address information of an NFT purchase page included in an NFT drop DB. In addition, a transaction for requesting to purchase the NFT for the digital product may be generated upon a request by the user.
Here, the transaction may include a signature proving that the transaction is requested from a genuine user. To do so, the TV platform 10 may be configured to include a cryptocurrency wallet in which a key for generating the signature is stored, or be connected to a module including the cryptocurrency wallet. Then, a transaction signed through the key stored in the cryptocurrency wallet is generated, and a purchase request including the signed transaction may be transmitted to the NFT market server 20.
Hereinafter, a detailed structure of the TV platform 10 according to an embodiment of the present disclosure is described with reference to
Meanwhile, the TV platform 10 may further include an external input device 11 configured to remotely control the TV platform 10. The external input device 11 may receive an input signal input by a user to perform power control, channel selection, screen settings, etc., and transmit a control signal corresponding to the received input signal to the TV platform 10. To do so, the TV platform 10 may be wiredly or wirelessly connected to the external input device 11.
Meanwhile, a selection signal by a user with respect to an NFT drop object displayed on a display unit of the TV platform 10 may be transmitted to the TV platform 10 through the external input device 11. To do so, the external input device 11 may include a preset key capable of directly selecting the displayed NFT drop object. When the user selects the preset key, the external input device 11 may transmit the selection signal for the NFT drop object to the TV platform 10. Then, the TV platform 10 may access an NFT purchase page of a digital product corresponding to the selected NFT drop object, and generate a purchase transaction for purchasing an NFT for the corresponding digital product according to a purchase request by the user through the accessed NFT purchase page.
Hereinafter, the TV platform 10 of
As illustrated in
In detail, among the components described above, the communication unit 110 may include one or more modules configured to allow wireless communication between the TV platform 10 and the broadcasting station server 30, or the TV platform 10 and a preset external server. The communication unit 110 may include at least one selected from a broadcast receiver module 111, a wireless Internet module 112, and a short-range communication module 113.
The broadcast receiver module 111 may receive a broadcast signal and/or broadcast-related information from a broadcasting station server through a broadcast channel. The broadcast receiver module 111 may include a tuner and a demodulator to receive radio frequency (RF) broadcast signals. That is, the broadcast receiver module 111 uses a tuner (not shown) to select an RF broadcast signal corresponding to a channel selected by a user, among RF broadcast signals received through an antenna, and converts the RF broadcast signal into an intermediate frequency signal or a baseband video/audio signal.
When the RF broadcast signal is a digital broadcast signal, the tuner may convert the RF broadcast signal into a digital intermediate frequency (IF) signal (DIF). On the other hand, when the RF broadcast signal is an analog broadcast signal, the tuner may convert the RF broadcast signal into an analog baseband video/audio signal (composite video banking sync (CVBS)/sound intermediate frequency (SIF)). As such, the tuner may be a hybrid tuner capable of processing a digital broadcast signal and an analog broadcast signal.
Meanwhile, the digital IF signal (DIF) output from the tuner may be input to the demodulator (not shown), and the analog baseband video/audio signal (CVBS/SIF) output from the tuner may be input to the control unit 180.

In this case, the first tuner may receive a first RF broadcast signal corresponding to a broadcast channel selected by the user, and the second tuner may sequentially or periodically receive a second RF broadcast signal corresponding to a pre-stored broadcast channel. The second tuner may convert the RF broadcast signal into a digital IF signal (DIF) or an analog baseband video/audio signal (CVBS/SIF) by using a same method as that by the first tuner.
The demodulator may receive the digital IF signal (DIF) obtained as a result of the converting by the tuner and perform a demodulation operation. To do so, the demodulator may include a trellis decoder, a de-interleaver, a Reed-Solomon decoder, etc., or a convolution decoder, a de-interleaver, a Reed-Solomon decoder, etc., depending on whether the digital IF signal is based on the ATSC method or the DVB method.
The demodulator may perform demodulation and channel decoding, and then, output a stream (transport stream (TS)) signal. In this case, the stream signal may be a signal in which an image signal, a voice signal, and a data signal are multiplexed. A signal output from the demodulator may be input to the control unit 180, and demultiplexing, image/voice signal processing, etc. may be performed on the input signal.
Meanwhile, the broadcast receiver module 111 may receive a broadcast signal received through a wired cable. A signal received through the wired cable may be a stream signal in which an image signal, a voice signal, and a data signal each related to broadcast content are multiplexed. In this case, the broadcast receiver module 111 may input the stream signal to the control unit 180. Then, the control unit 180 may perform demultiplexing and image/voice signal processing on the input stream signal and output a result of performing the processing through the output unit 150.

The sound output unit 152 may output audio signals related to functions performed by the TV platform 10 (e.g., an output of a broadcast image, an output of a digital product, etc.). To do so, the sound output unit 152 may include a speaker.
The interface unit 160 functions as a passage for various types of external devices connected to the TV platform 10. The interface unit 160 may include at least one selected from a wired/wireless headset port, a wired/wireless data port, a memory card port, a port which connects to a device equipped with an identification module, an audio input/output (I/O) port, a video I/O port, and an carphone port. In response to connection of an external device to the interface unit 160, the TV platform 10 may perform proper control related to the connected external device.
Meanwhile, the interface unit 140 may transmit a signal input by a user to the control unit 180 or transmit a signal transmitted from the control unit 180 to the user. To do so, the interface unit 140 may be connected to an external input device (e.g., a remote controller) (not shown) wiredly or wirelessly. Additionally, a user input signal input from a power key, a channel key, a volume key, a setting key, etc. through the connected external input device may be transmitted to the control unit 180. Here, the external input device may include at least one sensor configured to sense a gesture, a position, a touch, etc. of the user.
In addition, the memory 170 stores data supporting various functions of the TV platform 10. The memory 170 may store a plurality of application programs (or applications) run in the TV platform 10, information related to broadcast programs, or data and commands for operations of the TV platform 10. At least some of the application programs may be downloaded from an external server via wireless communication. In addition, at least some of the application programs may be present in the TV platform 10 from time of being released, to perform basic functions of the TV platform 10 (e.g., a broadcast signal reception function, a broadcast signal playback function, a broadcast program output function, etc.). The application programs may be stored in the memory 170 and installed in the TV platform 10 to be executed to perform an operation (or a function) designated by the control unit 180.
In addition to the operations related to application programs, the control unit 180 generally controls all operations of the TV platform 10. The control unit 180 may process signals or data received or input through the components described above, or process signals or data to be output. To do so, the control unit 180 may run an application program stored in the memory 170, output information according to a request by a user, or provide a function requested by the user.
In detail, when various data is received through the communication unit 110, the control unit 180 may control the output unit 150 to output image information and sound information according to the various data through the display unit 151 and the sound output unit 152. As an example, the control unit 180 may control the output unit 150 to output an image and sound of a particular broadcast channel through the broadcast receiver module 111, or control the output unit 150 to output multimedia data stored in an external device connected through the interface unit 160.
Alternatively, the control unit 180 may control the communication unit 110 to be connected to the NFT market server 20. In addition, the communication unit 110 may be controlled to receive an NFT drop DB for at least one digital product related to broadcast content currently output through the output unit 150 from the NFT market server 20. Then, when the NFT drop DB is received, the received NFT drop DB may be stored in the memory 170.
Here, the NFT drop DB may be updated by the NFT market server 20. For example, when received broadcast content is changed, the control unit 180 may request the NFT market server 20 for an NFT drop DB according to the changed broadcast content. Then, the control unit 180 may update a prestored NFT drop DB according to an NFT drop DB received from the NFT market server 20 in response to the request. Alternatively, the NFT market server 20 may transmit an NFT drop DB updated at a certain interval to the TV platform 10, and the control unit 180 may receive the updated NFT drop DB to update a prestored NFT drop DB.
Meanwhile, the control unit 180 may match a received NFT drop DB with a result of analysis performed by the scene analysis unit 130. In detail, the control unit 180 may match identification information corresponding to at least one digital product included in the NFT drop DB with the result of the analysis by the scene analysis unit 130 to detect whether a current broadcast scene includes feature information corresponding to the at least one broadcast scene. In addition, the display unit 151 may be controlled to display an NFT drop object corresponding to the at least one digital product corresponding to the detected feature information according to a result of the detection.
As such, when the NFT drop object is displayed, the control unit 180 may control the communication unit 110 to access an NFT purchase page in which an NFT for a specific digital product may be purchased based on a selection of the displayed NFT drop object by a user. In addition, when the NFT purchase page is accessed, a UI screen for the accessed NFT purchase page may be displayed on at least a part of the display unit 151. In addition, based on a user input to the UI screen, transaction information required by the NFT market server 20 to purchase the NFT for the specific digital product may be generated, and the generated transaction information may be transmitted to the NFT market server 20.
The transaction information may be transaction information including a transaction signature for verifying the user, that is, a signed transaction. In addition, the transaction signature may be generated based on a private key of the user. To do so, the memory 170 may include a cryptocurrency wallet 171 including the private key of the user and a public key. In addition, the control unit 180 may read the private key from the cryptocurrency wallet 171 to generate a transaction signature, and transmit a transaction including the transaction signature, i.e., a signed transaction to the NFT market server 20.
The cryptocurrency wallet 171 may be configured in a hardware type stored in a separate external module, instead of a software type stored in the memory 170. In this case, a cryptocurrency wallet module 171 including the cryptocurrency wallet may be connected to the control unit 180 through the interface unit 160. In addition, upon the connection of the cryptocurrency wallet module 171, the control unit 180 may read a private key from the cryptocurrency wallet module 171 and generate a transaction signature according to a request by the user. In addition, a transaction (a signed transaction) including a signature may be transmitted to the NFT market server 20.
The power supply unit 190 may be configured to receive external power or internal power and supply power needed for operation of respective components according to control by the control unit 180.
Referring to
As an example, a first key 301 may be a key for selecting an NFT drop object displayed on the display unit 151. In this case, when the first key 301 is selected by a user, the external input device 11 may transmit a selection signal for an NFT drop object to the TV platform 10. Then, the control unit 180 of the TV platform 10 may access an NFT purchase page corresponding to the NFT drop object selected according to an input of the first key 301. In addition, a UI screen of an accessed web page may be displayed on the display unit 151.
Meanwhile, the first key 301 may be a key further including another selectable function in addition to selection of an NFT drop object. In addition, one of a plurality of a plurality of functions corresponding to the first key 301 may be selected according to a period of time or a number of times for which the first key 301 is input, or intensity of an input of the first key 301.
Alternatively, a function corresponding to an input of the first key 301 may vary depending on an operating state of the TV platform 10. For example, when an NFT drop object is not displayed on the display unit 151, the TV platform 10 may perform a function related to playback of broadcast content based on an input of the first key 301, regardless of a purchase of an NFT for a digital product. On the other hand, when the first key 301 is input while an NFT drop object is displayed on the display unit 151, the TV platform 10 may access a web page (an NFT purchase page) for purchasing an NFT for a digital product corresponding to the NFT drop object based on the input of the first key 301. In addition, when the web page is accessed and the first key 301 is input while a UI screen of the accessed NFT purchase page is displayed, the TV platform 10 may end the access to the NFT purchase page based on the input of the first key 301. In this case, when the access to the NFT purchase page is ended, a screen of broadcast content may be displayed again in an area of the display unit 151 in which the UI screen of the NFT purchase page was displayed. That is, when an NFT drop object is displayed, the first key 301 may function as a toggle key for determining whether to access an NFT purchase page according to the displayed NFT drop object.
The configuration of the TV platform 10 according to an embodiment of the present disclosure and the external input device 11 capable of being connected to the TV platform 10 have been described above. Hereinafter, a process of operating the TV platform 10 to purchase an NFT for a digital product is described in detail with reference to a flowchart.
Referring to
When the NFT market application is activated in operation S400, the control unit 180 may determine whether a pre-generated NFT drop DB is present. According to whether a pre-generated NFT drop DB is present, digital product-related data for generating an NFT drop DB may be requested from the NFT market server 20 through the NFT market application activated in operation S400. Then, when the digital product-related data is received in response to the request, an NFT drop DB may be generated based on the received digital product-related data (S402).
Here, operation S402 may not be performed when a pre-generated NFT drop DB is present on the TV platform 10. Alternatively, operation S402 may include a process of, when a pre-generated NFT drop DB is present on the TV platform 10, transmitting version information of the pre-generated NFT drop DB to the NFT market server 20, and a process of, when the NFT market server 20 transmits the digital product-related data for updating the pre-generated NFT drop DB according to the version information, updating the pre-generated NFT drop DB based on the digital product-related data received from the NFT market server 20.
Accordingly, through operation S402, the TV platform 10 may include the NFT drop DB including information related to at least one digital product, i.e., identification information respectively corresponding to the at least one digital product, address information of an NFT purchase page respectively corresponding to the at least one digital product, and information about NFT drop objects respectively corresponding to the at least one digital product.
Then, the control unit 180 may receive broadcast content according to a channel selected by a user and output the received broadcast content (S404). Then, a feature point of a screen of the broadcast content currently being output, i.e., a broadcast scene may be analyzed (S406).
Here, the broadcast scene refers to a particular broadcast content scene, i.e., a scene, and may mean a scene of broadcast content is being currently broadcast on the TV platform 10 and displayed on a screen of the display unit 151. Alternatively, when the broadcast content is a drama or a movie, a scene may mean a series of situations or events that occur in a same background or location.
In addition, the feature point of the broadcast scene may mean at least one selected from a person, an object, a topographic feature, or a geographical location in the broadcast scene. For example, when broadcast content being output is a sports broadcast, a feature point of the broadcast scene may be a player or a team of players participating in a sports game. Alternatively, when the broadcast content being output is a movie or a drama, actors or actresses, costumes of actors or actresses, geographical features or geographical locations that serve as backgrounds for acting, etc. may be detected as a result of analyzing a feature point of the broadcast scene.
To analyze feature points of the broadcast scene, the control unit 180 may collect various information such as broadcasting program information (e.g.: EPG or IPG) of broadcast content, sound information such as a character's dialogue or a commentary, and a landmark included in the broadcast screen, and detect feature points of the broadcast scene based on the collected various information. In addition, the control unit 180 may detect feature points of the broadcast scene through face recognition or object recognition.
Then, the control unit 180 may determine whether a digital product related to the feature points of the broadcast scene detected in operation S406 is present, based on the pre-generated NFT drop DB (S408). As an example, the control unit 180 may detect whether identification information corresponding to the detected feature points of the broadcast scene, among identification information in the pre-generated NFT drop DB, is present.
Accordingly, when the currently output broadcast content is a sports broadcast and a play scene of a specific player is displayed on the display unit 151, the control unit 180 may identify a name of the specific player from an entry number or a face of the specific player whose play scene is displayed, or sports commentary information in operation S406. In addition, the identified player name may be detected as a feature point of a broadcast scene corresponding to the play scene. Then, the control unit 180 may search for presence of identification information of a digital product including the identified player name through the NFT drop DB described above with reference to operation S402. Then, based on a result of the searching, whether a digital product related to the detected feature point of the broadcast scene is present may be determined.
As a result of the determination in operation S408, when identification information of a digital product corresponding to the detected feature point of the broadcast scene is present, the control unit 180 may display, on one area of the unit 151, an NFT drop object corresponding to the identification information of the digital product, from the NFT drop DB (S410).
Here, the NFT drop object may include information corresponding to the feature point of the broadcast scene so that the user may identify the feature point of the broadcast scene. As an example, when the play scene of the specific player is displayed on the display unit 151 as described above, the control unit 180 may display an NFT drop object on one area of the display unit 151, the NFT drop object including at least one piece of feature information of a detected broadcast scene, i.e., a name or a signature of the specific player or information which enables to identify the specific player (e.g., a face image of the specific player).
Meanwhile, when the NFT drop object is displayed on one area of the display unit 151, the control unit 180 may determine whether the displayed NFT drop object is selected by a user (S412). For example, when a preset input is applied from the user, the control unit 180 may determine that the NFT drop object is selected by the user. Here, the preset input by the user may be a preset key input, a preset gesture, or an input of preset authentication information.
As an example, the control unit 180 may detect a gesture of the user from the user's image detected through the camera 121. In addition, when the gesture of the user detected through the camera 121 corresponds to a preset gesture, it may be determined that the NFT drop object is selected by the user. Alternatively, the preset gesture may be determined based on movement of the external input device 11. That is, when the user performs a preset gesture while holding the external input device 11, the external input device 11 may detect movement according to the preset gesture by the user, based on a detection value detected from at least one motion detection sensor such as a gyroscope, an acceleration sensor, etc. Then, when the detected movement matches the movement corresponding to the preset gesture, the external input device 11 may determine that the user has performed the preset gesture, and determine that the NFT drop object is selected by the user.
Alternatively, when the preset authentication information is input, the control unit 180 may determine that the NFT drop object is selected by the user. For example, when biometric information such as the user's voice information input through the microphone 122 or the user's fingerprint information detected from the external input device 11 held by the user's hand is detected, the control unit 180 may determine that the NFT drop object is selected by the user. To do so, the external input device 11 may include at least one sensor configured to detect the biometric information of the user.
Alternatively, when a preset key is input, the control unit 180 may determine that the NFT drop object is selected by the user. Here, the preset key may be one of keys on the user input unit 123 included in the TV platform 10. Alternatively, the preset key may be any one of the keys included in the external input device 11 as shown in
Meanwhile, as a result of the determination in operation S412, when the NFT drop object is not selected by the user, the control unit 180 may determine whether time that has clapsed since the NFT drop object was displayed exceeds designated time (S418). When the time that has elapsed since the NFT drop object was displayed is less than the designated time, operation S412 may be performed again to determine whether the NFT drop object is selected by the user. However, when the NFT drop object is not selected by the user until the designated time is exceeded, the control unit 180 may end the displaying of the NFT drop object (S420). Then, the control unit 180 may proceed back to operation S404 to output a broadcast screen according to the received broadcast content on the display unit 151.
Meanwhile, the designated time in operation S418 may be determined differently depending on a type of broadcast content being output or characteristics of a broadcast scene. For example, like a movie or a drama, when images captured in a same place or background or in a same space for a certain period of time constitute one broadcast scene, the designated time may be time corresponding to time for which the broadcast scene is output onto a screen That is, while the images captured for a certain period of time in the same place or background or the same space are output via the display unit 151, an NFT drop object related to the broadcast scene may be displayed.
On the other hand, in a case when a particular event (e.g.: appearance of a specific player or a play of a specific player) constitutes a broadcast scene like sports broadcasting, the control unit 180 may maintain a state of displaying the NFT drop object for a certain period of time. This is because when a broadcast scene is constituted by an event that occurs irregularly like sports broadcasting, time for outputting the broadcast scene may be too short, and therefore, when displaying of the NFT drop object is ended too quickly, a user may not easily purchase an NFT for a digital product related to the broadcast scene. Accordingly, while a screen of broadcast content such as sports broadcasting is output, even when a broadcast scene corresponding to an NFT drop object is no longer displayed on a screen, the control unit 180 may maintain a state in which the NFT drop object is output for preset minimum time.
Meanwhile, as a result of the determination in operation S412, when the displayed NFT drop object is selected by the user, the control unit 180 may detect, from the NFT drop DB, an address of an NFT purchase page corresponding to the currently selected NFT drop object. Then, the detected NFT purchase page may be accessed (S414). Then, a UI screen of the currently accessed NFT purchase page may be displayed on at least a part of the display unit 151. To do so, the TV platform 10 may include a web browser capable of accessing a web page and displaying a UI screen of the web page, and display a screen of the web page (an NFT purchase page) accessed by the web browser on at least a part of the display unit 151.
Here, the NFT purchase page may include various information related to purchase of the digital product corresponding to the NFT drop object selected by the user. For example, the NFT purchase page is an NFT purchase page in which the NFT for the digital product may be purchased, and may be a web page provided in an NFT marketplace. That is, when the user selects an NFT drop object, the TV platform 10 may perform an access to the NFT market server 20, and access the NFT marketplace through the NFT market server 20.
Meanwhile, the NFT purchase page may include various information related to an NFT for a specific digital product. As an example, the NFT purchase page may include a name of a current owner (an owner of an NFT) of a digital product. In addition, NFT history information (history) including information about an original owner of the NFT and a previous owner of the NFT may be included. In addition, information about a price of the NFT for the digital product may be included.
As such, when various information related to the NFT for the digital product corresponding to the output NFT drop object is displayed, the control unit 180 may detect an input by the user to purchase the NFT for the digital product. In addition, when the input by the user is detected, the NFT for the digital product may be purchased (S416).
Here, the input by the user may be a preset key input, a preset gesture, or an input of preset authentication information. Here, the gesture may be detected from movement of the camera 121 in the TV platform 10 or the external input device 11. In addition, the preset authentication information may be input through the user input unit 123 or the microphone 122 of the TV platform 10, or a biometric information detection sensor disposed in the external input device 11. In addition, the preset key may be input through the user input unit 123 in the TV platform 10 or a particular key on the external input device 11.
When the input by the user is detected, the control unit 180 may generate a purchase transaction for purchasing an NFT for a digital product corresponding to the output NFT drop object. Then, the TV platform 10 may transmit the generated purchase transaction to the NFT marketplace. In this case, the purchase transaction may include a signature of an authenticated user, and when it is proved that the signature of the authenticated user is genuine, the purchase of the NFT according to the purchase transaction may be completed. Then, the NFT market server 20 may update an NFT status of the digital product by distributively storing NFT owner change history according to sale of the NFT in a plurality of terminals through the blockchain network.
Meanwhile, when the purchase of the NFT for the digital product is completed through operation S416, the control unit 180 may end the displaying of the NFT purchase page. Therefore, the access to the NFT purchase page may also be ended. Then, the control unit 180 may proceed to operation S404 to output a broadcast screen according to the received broadcast content on the display unit 151. Then, a process after operation S404 may be performed again.
Meanwhile, the TV platform 10 according to an embodiment of the present disclosure may include a plurality of NFT drop DBs. For example, the TV platform 10 may include a plurality of different NFT drop DBs corresponding to a type of broadcast content (e.g., a genre), a broadcasting station server providing the broadcast content, or a broadcast channel. In addition, as such, when the plurality of different NFT drop DBs respectively corresponding to a type of the broadcast content, a broadcasting station server, or a broadcast channel are included, the control unit 180 may select at least one NFT drop DB among the plurality of NFT drop DBs based on broadcast content currently output on the display unit 151, and output, onto the display unit 151, an NFT drop DB that matches a feature point of a broadcast scene based on the selected at least one NFT drop DB.
Referring to
In this case, the at least one NFT drop DB selected in operation S502 may be used to detect identification information of a digital product corresponding to the detected feature point of the broadcast scene in operation S408 of
Meanwhile, when the at least one NFT drop DB is selected in operation S502, the control unit 180 may check whether broadcast content output through the display unit 151 is changed (S504). Here, the change of the broadcast content means that broadcast content received to the TV platform 10 is changed, and may occur when a user changes a broadcast channel. In other words, operation S504 may be an operation of checking whether the user has changed the broadcast channel.
Here, in a case when the broadcast channel is changed, the control unit 180 may determine that the broadcast channel has been changed only when broadcast content of a broadcast channel obtained as a result of the changing is output for more than a certain period of time. Accordingly, when the user changes a broadcast channel for channel search, whether broadcast content is changed may not be checked with respect to broadcast content output through broadcast channels temporarily selected for the channel search.
As a result of the checking in operation in S504, when the broadcast channel is changed, the control unit 180 may detect characteristics of a broadcast content of a broadcast channel obtained as a result of the changing (S506). In this case, the control unit 180 may detect a type of the broadcast content received through the broadcast channel obtained as a result of the changing, a broadcasting station server providing the broadcast content, or the broadcast channel obtained as a result of the changing. Then, whether characteristics of the detected broadcast content are different from those of the broadcast content detected in operation S500 may be checked (S508). In addition, when the characteristics of the broadcast content are different, the control unit 180 may proceed back to operation S502 to select at least one NFT drop DB corresponding to the broadcast content obtained as a result of the changing.
For example, when a user changes a broadcast channel from a first channel to a second channel, both the first channel and the second channel may be sports broadcast channels. Accordingly, both the first channel and the second channel may be channels through which broadcast content related to sports broadcasting is output. Then, the control unit 180 may determine that the characteristics of the broadcast content are not changed in operation S508. In this case, the control unit 180 may not newly select an NFT drop DB.
In this case, the control unit 180 may check whether the broadcast content output through the first channel and the second channel both correspond to a same type of sports game. Then, only in a case when the first and second channels output broadcast content about a same type of sports game, it may be determined that characteristics of the broadcast content are not changed. Accordingly, when the broadcast content in the first channel is about a sports game different from that in the second channel, the control unit 180 may determine that characteristics of the broadcast content are changed, and proceed back to operation S502 to reselect at least one NFT drop DB corresponding to broadcast content obtained as a result of changing the broadcast channel.
Also, as described above, when a user changes a broadcast channel from the first channel to the second channel, although the first and second channels are different from each other, the first and second channels may be channels that transmit broadcast content from a same broadcasting station server. In this case, the control unit 180 may determine that the characteristics of the broadcast content are not changed in operation S508. Then, the control unit 180 may not newly select an NFT drop DB.
Meanwhile, when the broadcast content output in operation S504 is not changed, that is, when the broadcast channel is not changed or when characteristics of the broadcast content being output are not changed as a result of the determination in operation S508 although the broadcast content being output is changed, the control unit 180 may check whether update data for updating an NFT drop DB is received from the NFT market server 20 (S510). In addition, when the update data is not received, the control unit 180 may proceed back to operation S504 to check whether the broadcast content output through the display unit 151 is changed.
On the other hand, as a result of the checking in operation S510, when update data is received from the NFT market server 20, at least one of a plurality of pre-generated NFT drop DBs may be updated based on the received update data (S512). In this case, when an NFT drop DB corresponding to the update data is not present, a new NFT drop DB including the update data may be generated. In addition, the control unit 180 may proceed back to operation S504 to check whether the broadcast content output through the display unit 151 is changed.
Meanwhile, according to a result of the determination in operation S508, when operation S502 is performed again to select at least one new NFT drop DB according to the broadcast content obtained as a result of the changing, an NFT drop DB corresponding to the broadcast content obtained as a result of the changing may not be present in the TV platform 10. In this case, the control unit 180 may request the NFT market server 20 for digital product-related data according to characteristics of the broadcast content obtained as a result of the changing. Then, the control unit 180 may generate a new NFT drop DB based on digital product-related data received in response to the request, and the generated new NFT drop DB may be selected.
As such, when a plurality of NFT drop DBs are included and an NFT drop object is output based on one NFT drop DB determined according to broadcast content which is received and output, a size of an NFT drop DB in which identification information according to a feature point of a broadcast scene is to be searched for may be reduced. Accordingly, time needed to detect an NFT drop object corresponding to a feature point of a broadcast scene may be reduced. Thus, time needed to purchase an NFT for the digital product according to the operation process of
The operation process of the TV platform 10 has been described above in detail, the operation process being configured such that an NFT drop object indicating that a digital product related to a broadcast scene is present is output as a result of analyzing the broadcast scene through the TV platform 10 according to an embodiment of the present disclosure, and a user may purchase an NFT for a digital product related to the broadcast scene based on a selection by the user with respect to the NFT drop object.
Hereinafter, an example of outputting an NFT drop object from the TV platform 10 according to an embodiment of the present disclosure, and purchasing an NFT for a digital product according to selection of the NFT drop object is described with reference to
Referring to
As such, when at least one NFT drop DB according to characteristics of the broadcast content being output is selected, the control unit 180 of the TV platform 10 may analyze a broadcast scene output onto the display unit 151, that is, a broadcast scene. Accordingly, as shown in
As a result of the detection, when digital product-related data corresponding to the detected name of the player is present, the control unit 180 may output an NFT drop object 600 included in the detected digital product-related data onto the display unit 151. In this case, the NFT drop object 600 may include information about a relevant digital product. For example, when the relevant digital product is a player card including a handwritten signature of the specific player, the NFT drop object 600 may include an image related to the handwritten signature of the specific player.
In addition, the NFT drop object 600 may further include information that allows to identify a player corresponding to the displayed NFT drop object 600, among players appearing in the broadcast scene. As an example, as shown in
As such, when the NFT drop object 600 is displayed in one area of the display unit 151, the control unit 180 of the TV platform 10 may determine whether the user has selected the NFT drop object 600. As an example, as shown in
Meanwhile, when the user has selected the NFT drop object 600 output onto the display unit 151, the control unit 180 of the TV platform 10 may access an address of an NFT purchase page corresponding to the NFT drop object 600 to display a web page in which an NFT for a digital product corresponding to the NFT drop object 600 may be purchased, i.e., an NFT purchase page.
Referring to
For example, as presented in the NFT purchase page accessed screen 700 of
As such, when the NFT purchase page accessed screen 700 for the digital product corresponding to the NFT drop object 600 is displayed, the control unit 180 of the TV platform 10 may request to purchase the NFT for the digital product 720 according to a selection by the user. As an example, when a user selection such as an input of a designated key is present, the control unit 180 may display a purchase option menu 710 including an NFT purchase request 711 and a purchase cancellation 712 for the digital product 720 as shown in
In addition, when the user selects the NFT purchase request 711 in the purchase option menu 710, the control unit 180 may generate a purchase transaction for purchasing an NFT for the digital product 20. Then, the generated purchase transaction may be transmitted to the NFT market server 20. Then, the NFT market server 20 may update an NFT status of the digital product 20 through a blockchain network to purchase the NFT for the digital product 20.
An example in which only one NFT drop object is displayed has been described above. However, when feature points detected in a broadcast scene match identification information corresponding to one or more digital products, the one or more NFT drop objects may be displayed on the display unit 151. In this case, the control unit 180 of the TV platform 10 may select one of a plurality of NFT drop objects output based on an input via the user input unit 123 or the external input device 11, or a gesture or a voice signal. Then, the TV platform 10 may access an NFT marketplace and output an NFT purchase page in which an NFT for a digital product corresponding to the selected one NFT drop object may be purchased.
Meanwhile, as described above, when the NFT for the digital product is purchased through the TV platform 10, the control unit 180 of the TV platform 10 may obtain information about the NFT for the digital product purchased by a user. Accordingly, the control unit 180 may determine whether identification information of a digital product corresponding to a feature point detected from a currently output broadcast scene is identification information of a digital product previously purchased by the user. In addition, as a result of the determination, when the identification information of the digital product corresponding to the feature point detected from the currently output broadcast scene is one of pieces of the identification information of the digital product previously purchased by the user, the control unit 180 may not display an NFT drop object corresponding to the digital product. That is, the control unit 180 may limit displaying of an NFT drop object corresponding to the digital product previously purchased by the user on the display unit 151 not to display the NFT drop object.
