[0001] The present invention relates to Video distribution system and video distribution method .

Background Art

[0002] In recent years, with the evolution of networks, many video distribution services have been implemented. In particular, large-sized, large-screen television receivers can not only receive broadcasts as before, but also be connected to a network and play the distributed videos, enabling users to enjoy higher-quality and more immersive videos. This has become possible due to the high-speedization of the network and the improvement of the processing performance of television receivers. In the future, it is considered that the opportunities to display and operate various contents provided by the network on television receivers will increase.

[0003] Video distribution services have become more advanced, and not only simple video viewing, but also so-called interactive services that link videos and web information, such as guiding from video content to an EC (electronic commerce) site to purchase goods and checking details in a video from web information on the Internet (such as news and ticket information), have been developed.

[0004] In such a situation, it is a very important theme in the future progress of networking that a television receiver that can be easily used at home becomes a means to provide users with videos provided by the network, web site information, EC services, etc.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The evolution of networks has made it easier to implement video streaming services than before. However, there are various challenges in receiving online video streaming services on television receivers, and it has not achieved the same level of widespread reception as broadcast television. Furthermore, while information terminals such as PCs now offer more advanced network services through the linking of streamed videos and web content, such linked services have been difficult to implement on conventional television receivers.

[0007] While terrestrial broadcasting uses a unified standard for video content, network-based video content is distributed using multiple distribution methods. Therefore, in order to select and receive video content distributed from a specific video platform, the receiver needed to be equipped with special functions. Furthermore, in order to receive video content distributed to a television broadcast receiver, the television receiver needed to have the ability to connect to a network and the performance to play the received video content.

[0008] Depending on the functions and performance of the television receiver, some streaming video content can be received while others cannot. Therefore, traditional video streaming services relied on video platforms and receiving terminals each employing their own unique streaming technologies. From the video platform's perspective, this required individual support for multiple receiving terminals with varying performance and functions; conversely, from the receiving terminal's perspective, it required individual support for multiple video platforms with different streaming methods. Furthermore, the variety of methods for selecting video content meant that a consistent program selection method could not be provided, leading to user confusion. This situation not only hinders the widespread adoption of video streaming but also poses a significant challenge from the perspective of user convenience.

[0009] On the other hand, when linking video content and web content to provide interactive services, television receivers are operated via remote control, which is extremely inconvenient compared to the keyboard and mouse input functions of information terminals such as PCs. This makes it difficult for users to comfortably operate and receive advanced services. Furthermore, since such advanced services are implemented through the cooperation of video platforms and websites, it is difficult to provide such integrated services in common across different video platforms and television receivers with different functions and performance.

[0010] Figure 16 shows a configuration diagram of a conventional video distribution system. In Figure 16, CSPs (Content Service Providers) 101 to 108 provide video content. The video content is input to video platforms 1611 to 1613, respectively. Video platforms 1611 to 1613 send video streams to television receivers 141 to 150. Because each video platform has a different distribution method, each video stream is received by only a limited number of television receivers. In this conventional example, video platform 1611 is receivable by television receivers 141 to 143, video platform 1612 is receivable by television receivers 144 to 147, and video platform 1613 is receivable by television receivers 148 to 150. It is difficult to distribute video content widely and commonly to television receivers with different functions. Furthermore, when providing a service that links a website 1601 connected to the video platform 1613 with video output from the video platform 1613, the limited functionality of a standard television remote control, such as up, down, left, right, and number buttons, placed a significant burden on the user.

[0011] Figure 17 illustrates the operation of selecting video content from a conventional video distribution system. For example, television receivers 144-147 in Figure 16 receive signals from both video platforms 1612 and 1613. As shown in 1701, the user first selects from the platform selection screen 1701 using the video platform buttons 1702 and 1703. Each button is configured on the television receiver side by video platform selection metadata 1712 and 1722 provided by the respective video platform. Pressing either button proceeds to the content selection screen 1710, where content is selected by pressing the content buttons 1711-1716. These buttons are generated by content metadata 1723 provided by the video platform. This selection operation is performed using the television remote control 1731.

[0012] Furthermore, if video content and web content are linked after content selection, for example, if video content 1741 and web content 1742 are displayed simultaneously, more complex operations are required, increasing the user's operational burden on the TV remote control 1731. Consequently, limitations are placed on the display of content. [Means for solving the problem]

[0013] A video distribution system comprising a TV gateway and a TV cloud system connected between the TV gateway and a TV receiver, which provides a content service provider's content to a TV receiver, is characterized in that the TV gateway receives content information in different formats from multiple video platforms that aggregate and distribute content information from content service providers, converts the received content information into common content selection data, and the metadata present in the content selection data includes video and audio format information, and the TV cloud system converts the content selection data output from the TV gateway into information corresponding to the functions and performance of the TV receiver and distributes it to the TV receiver, and determines whether or not the content can be played by comparing the video and audio format information with the functions and performance information of the TV receiver. [Effects of the Invention]

[0014] This configuration allows each video platform to present content to all television receivers with a single format input, without having to worry about the different performance and functions of the television receivers, simply by inputting to the television gateway. Furthermore, by linking the television receiver with a mobile device such as a smartphone, it is possible to improve the usability of advanced services by using a mobile device instead of a single-function remote control with different operability, and to perform advanced smartphone-television coordination operations that are not possible with existing remote controls. In this process, by combining the ID of the television receiver and the ID of the mobile device, the system can automatically present services from websites linked to each video platform, significantly improving user convenience.

Embodiments for Carrying Out the Invention

[0016] Hereinafter, embodiments related to the present invention will be described in detail with reference to the drawings. The present invention enables easier selection of video content when selecting video content sent from a plurality of video distribution platforms, which is implemented using a network, on television receivers with different performances and functions. Furthermore, the present invention relates to an interlocking system for video distribution and web content that is suitable for operating in conjunction with services such as EC, news, or travel information, etc., provided as web content, along with the video content. The system is composed of a video platform with different functions and a television receiver with different functions and performances. The present invention implements a good video viewing environment and, furthermore, an advanced service that links video and web content in such a system environment.

[0017] In the present invention, these problems are solved by installing a TV gateway and enabling cooperation between a mobile terminal and a television receiver. Furthermore, in this invention, content from different video platforms is first received by a television gateway. The output from the television gateway is then input to a TV cloud connected to televisions having substantially equivalent performance and functionality. Here, the television gateway converts the input from the video platform into a format that can be commonly provided to the TV cloud. The TV cloud then generates screen data configurations that can be selected by the managed televisions connected to it, forming the optimal content selection screen for each television receiver.

[0018] (First Embodiment) A first embodiment relating to the present invention is shown in Figure 1. Unlike conventional video distribution systems, the TV gateway 121 and TV clouds 131-134 are located between the video platforms 111-113 and the TV receivers 141-150. The video content provided by CSP101~108 and the information for content selection are input to the TV gateway 121 by the video platforms 111~113, respectively. After the TV gateway 121 converts the information for video content selection, it inputs it to the TV clouds 131~134. TV clouds 131-134 receive information from the TV gateway 121, and this information is converted into data that the TV receiver uses to configure the screen for content selection.

[0019] TV Cloud 131 generates and transmits content selection screen data to the connected and managed television receiver groups 141-143, each with nearly equivalent functionality. Similarly, TV Cloud 132 outputs to television receiver groups 144-145, TV Cloud 133 outputs to television receiver groups 146-147, and TV Cloud 134 outputs to television receiver groups 148-150. Each of these television receiver groups is managed as a cluster with nearly equivalent functionality and performance. Here, TV clouds 131-134 each contain information about the functions and performance of the connected televisions, generate screen data for selecting receivable content for the television receivers, and each television receiver configures the optimal screen based on that data. The above operations make it possible to select video content from different video platforms on television receivers with different functionalities.

[0020] The following describes the details of how this system works. Figure 2 shows an example of the program selection screen provided by this embodiment. From video platforms 111-113, information for content selection, including a timetable 201, content metadata 202, and banner data 203, is provided to the TV gateway 121. This data is dependent on video platforms 111-113 and is in a different format. Next, the TV gateway 121 converts this timetable 201, content metadata 202, and banner data 203 into a common content selection data 204 for supply to each TV cloud 131-134. Here, the content selection data 204 includes a timetable and channel number for banner placement, as well as metadata describing the content.

[0021] TV clouds 131-134, having received content selection data 204 from the TV gateway 121, generate content selection screen data 210 according to the functions and performance of each TV receiver. At this time, video content provided by video platforms 111-113 is assigned to one or more channels, allowing users to select video content without being aware of the differences between video platforms. This screen is ultimately created by the TV receiver's browser based on the content selection screen data 210. Here, metadata includes video and audio format information, and playback is determined by comparing this with the TV receiver's function and performance information. TV reception function and performance information is maintained by each TV cloud, and programs that cannot be played are grayed out on the content selection screen.

[0022] The details of the above operations are shown in Figure 3. The video platforms 111-113 provide the TV gateway 121 with datasets 301-303 containing timetables, content metadata, and banner data. However, datasets 301, 302, and 303 are not guaranteed to be interoperable and are provided in different formats. The TV gateway 121 converts these datasets into a common content selection data 204. Each TV cloud 131-134 receives the content selection data 204 provided by the TV gateway 121 and generates content selection screen data 341 and 344, respectively. Here, TV cloud 131 and TV cloud 134 are shown as examples. For example, TV cloud 131 generates content selection screen data 341 for the connected TV receivers 141-143, and TV cloud 134 generates content selection screen data 344 for the connected TV receivers 141-150. Each TV receiver then displays the content based on this data.

[0023] (Second embodiment) Figure 4 shows a second embodiment based on the present invention. This embodiment adds mobile terminals 401-410, a viewing data storage unit 451, an ID linking information storage unit 452, a content recommendation information storage unit 453, a recommended advertisement selection and insertion unit 454, and an advertisement server 455 compared to the first embodiment. In this embodiment, the process is the same as in the first embodiment up to the generation of the content selection screen, but the television receivers 441-450 and the mobile terminals 401-410 are linked by their respective IDs (individual identification data). In addition, each television receiver 441-450 has a function to measure what the user is watching as viewing data, and the measured viewing data is uploaded to the television gateway 421 via the television cloud 431-434.

[0024] The TV gateway 421 is connected to a viewing data storage unit 451 and an ID combination information storage unit 452. Viewing data obtained from TV receivers 441-450 is stored in the viewing data storage unit 451 via TV clouds 431-434 and the TV gateway 421. In addition, ID combination information of TV receivers 441-450 and mobile terminals 401-410 is added to the ID combination information storage unit 452. The content recommendation information storage unit 453 calculates which TV receivers tend to view what kind of content based on the information from the viewing data storage unit 451 and the ID combination information storage unit 452, and transmits this information to the video platforms 411-413. This calculation is achieved by measuring the viewing time for each genre of content viewed, etc.

[0025] Meanwhile, the recommended ad selection and insertion unit 454 calculates which television receiver should insert which ad based on the viewing data storage unit 451 and the ID linking information storage unit 452, retrieves the desired ad from the ad server 455, and inserts the ad into the video content of the video platforms 411 to 413.

[0026] Figure 5 shows an example of the ID configuration and combination in the present invention. Mobile terminals 401-410 have an SP-ID (Smartphone ID) 501. On the other hand, television receivers 441-450 have a TV-ID (Television ID) 511. The SP-ID consists of a PF-ID, which is the ID of the video platform, and a UR-ID, which is the ID of the user. The TV-ID consists of a TC-ID, which is the ID of the TV cloud, and a DV-ID, which represents the television receiver itself as a device. The ID combination information storage unit 452 contains a table 520 showing the combination information of the SP-ID and the TV-ID, and the television receiver and mobile terminals form a linked state by ID. Here, in Table 520, "○" indicates a linked state, and "―" indicates a non-linked state. Here, a single television receiver may be linked to multiple mobile terminals.

[0027] Figure 6 shows the ID combination method and the data stored in each. The television receiver 141 and a mobile terminal 401 such as a smartphone transmit an authentication code 611 to the mobile terminal 401 via a QR code (registered trademark) or the like displayed on the television receiver. This authentication code and the corresponding television are pre-stored in the television ID storage unit 603 of the television cloud 431. Authentication code 611 is a time-limited authentication code corresponding to the TV-ID individually assigned to the television receiver 141. This authentication code 611 is sent from the TV cloud 431 to the television receiver 141. At the same time, the TV cloud 431 sends the authentication code 611 along with address information for connecting to the video platform 411 to the mobile terminal 401.

[0028] The authentication code 611 is sent from the smartphone 401 to the video platform 411 as data 612 along with the SP-ID of the mobile terminal. The video platform 411 then retrieves user attributes from its customer data storage unit 601 based on the acquired authentication code 611 and the SP-ID of the linked mobile terminal 401, and sends them together with the SP-ID as data 613 to the television gateway 421. The TV gateway obtains the authentication code, SP-ID, and user attributes as data 613, and then queries the TV cloud 431 based on the authentication code to obtain the corresponding TV-ID. Here, the TV cloud 431 manages the TV-IDs of the TV receivers under its control, has a correspondence table between TV-IDs and authentication codes in the TV ID storage unit 602, and obtains which TV receiver is the target of the connection from the authentication code. The authentication code placed in data 612 and data 613 is the same as the authentication code 611. Through these operations, the TV gateway 421 combines the TV-ID and SP-ID and stores them in the ID combination information storage unit 602. Furthermore, it notifies the video platform 411 of the combined TV-ID and SP-ID information using the passkey 621. The passkey 621 is the key to the database of the ID combination information storage unit 602, and by sending the passkey 621 to the TV gateway 613, the SP-ID, TV-ID, and user attributes can be retrieved. Through the above operations, the mobile terminal and the television receiver are linked by ID. After the ID linking, the video platform 411 can then deploy services to the target television receiver using the passkey 621 transferred from the television gateway 421 to the video platform 411. The passkey 621 is stored in the customer data storage unit 601 so that its correspondence with the SP-ID can be identified. Although Figure 6 illustrates the case of video platform 411, the same operation is performed for video platforms 412 and 413.

[0029] Figure 7 shows the content selection screen when IDs are combined. When the TV-ID and SP-ID are linked, the PF-ID, a component of the SP-ID, allows the system to determine which video platform the user is a customer of. Therefore, channels provided by the corresponding video platform are displayed in an easily accessible location on the content selection screen. For example, in Figure 7, if SP-ID 501 includes the ID of video platform 411, channels provided by video platform 411 are displayed as the initial screen, making selection easier for the user. Furthermore, by inferring viewing trends from the viewing data of the television receiver identified by the TV-ID, recommended content 701, 702, and 703 are displayed simultaneously. In this way, by linking IDs, users can be given priority in receiving content from the corresponding video platform, making it easier for them to access the services offered by that platform.

[0030] Figure 8 shows an example of a screen display that links video content and web services. When TV-ID511 and SP-ID501 are connected, the TV receiver indicated by TV-ID automatically displays a web service screen linked to the video platform indicated by SP-ID501. This allows users to access not only video viewing but also related information and product descriptions from e-commerce sites. Furthermore, the mobile app 812 displayed on a mobile device can be linked with the video screen 811, enabling video content selection methods not possible with a regular remote control. For example, by touching an interesting news article on a news site within the mobile app on the mobile device, related video content can be played on the TV receiver, enabling unprecedented content selection. On the other hand, by displaying an e-commerce site on the mobile app and tapping an interesting product, users can view detailed product descriptions via video, providing an unprecedented user experience.

[0031] The above operations will be explained in detail using Figure 9. When video content from video platform 411 is linked to website 901, web link information 902 is input from video platform 411 to television gateway 421. In addition to the conventional timetable 201, content metadata 202, and banner data 203, recommended content data 901 is also input to television gateway 421. The TV gateway 421 transfers the combined TV-ID 501 and content selection data 204, as well as the recommended metadata 911 created from the recommended content data 901 and the destination URL obtained from the web link information, to the TV cloud 431. The TV cloud 431 then displays the recommended content on the content selection screen. data 914 is generated and sent to the television receiver 441. At that time, the destination URL is set in the television receiver 441 along with the channel and time information so that it can link to video content. Based on the specific channel and time of viewing, the television receiver 441 displays the web content indicated by the destination URL on the television screen when the user presses a link button or similar.

[0032] When using a mobile app, the mobile app is downloaded from website 901 to mobile terminal 401, and then the operation results of the mobile app and the SP-ID are sent to video platform 411. Subsequently, the video platform 411 sends the passkey and mobile operation to TV gateway 421, which converts them into common TV operation codes 903, and then TV cloud 431 converts them further into TV operation codes to control TV receiver 441. The passkey is obtained from customer data storage unit 601, which is a correspondence table with SP-ID. The above explanation pertains to video platform 411, but the same operation applies to other video platforms. Furthermore, the same operation applies to TV clouds other than TV cloud 411 and TV receivers other than TV receiver 441.

[0033] Figure 10 illustrates the content recommendation and advertisement insertion based on the present invention. The information from the viewing data storage unit 451 and the ID linking information storage unit 452 is input to the content recommendation information storage unit 453, which calculates television viewing trends and determines recommended content and desirable advertisement candidates. Based on the information from the content recommendation information storage unit 453, recommended advertisements are obtained from the advertisement server 455, and the video platform 411 inserts advertisements into the video content based on the output of the recommended advertisement selection and insertion unit 454. On the other hand, the receiving ad insertion unit transfers desirable ads from the ad server 455 based on the information in the content recommendation information storage unit 453, and the television receiver 141 inserts the ads into the content based on the output of the receiving ad insertion unit 456. For example, if video platform 411 distributes video using a multicast method, it is not possible to insert individual advertisements for each television receiver. In this case, video platform 411 first inserts an advertisement and distributes a common advertisement, and then the television receiver overwrites it with the desired advertisement individually. This operation makes it possible to present user-specific advertisements, such as targeted advertising, to individual television receivers.

[0034] Figure 11 shows a diagram of the configuration of a television receiver related to the present invention. The antenna 1101 receives the broadcast, and the tuner 1102 converts the broadcast content into a digital stream. The signal processing unit 1103 then converts the broadcast content into audio and video signals. The audio signal is processed by the audio processing unit 1104, and the audio is played back by the speaker 1106. The video signal is processed by the video processing unit 1105, and the video is played back by the video display unit 1107. The CPU 1109 is connected to the memory 1108 and the non-volatile memory 1110, and a control program is executed to control the tuner 1102 and the signal processing unit 1103. User operations are input from the remote control 1113 to the receiver 1112, and then to the control program. The communication interface 1111 receives video content and content selection screens distributed from the network, and the CPU 1109's control program processes them.

[0035] Figure 12 shows a configuration diagram of the video platform related to the present invention. The CPU 1202 is connected to the memory 1201 and the storage device 1203 and executes a control program. The operator controls the operation via the operation unit 1205. The communication interface 1204 is connected to the network and performs input / output of video content, video distribution, and input / output of content selection information. The video processing unit 1206 encodes and encrypts the input video content and generates a video distribution stream.

[0036] Figure 13 shows a diagram illustrating the configuration of a television gateway related to the present invention. The CPU 1302 is connected to the memory 1301 and the storage device 1303, and runs a predetermined processing program. The interface 1304 handles input / output from the video platform and input / output to the TV cloud. The operator controls the operation using the control unit 1305.

[0037] (Third embodiment) Figure 14 shows a diagram illustrating the configuration of a third embodiment related to the present invention. The difference from the second embodiment is that conversion units 1411-1413 are inserted between the video platforms 411-413 and the telegateway 1412. In this embodiment, different data output from different video platforms 411-413 are converted into common data in advance by the converters 1411-1413 and then input to the television gateway 1412. This process reduces the processing load on the television gateway 1412 because it processes common data. These conversion units 1411-1413 may be provided within the television gateway 1412 as an input interface for the television gateway 1412, or they may be provided within the video platforms 411-413 as an output interface for the video platforms 411-413. In the second embodiment, different data was directly input from video platforms 411-413 and converted to common data internally, whereas in the third embodiment, the conversion to common data is requested from each video platform 411-413. This allows for load distribution.

[0038] Figure 15 shows an explanatory diagram of the operation of a third embodiment related to the present invention. The difference from the operation description of the second embodiment shown in Figure 9 is that a conversion unit 1411 is inserted. The conversion unit 1411 performs data conversion, and the common timetable 1501, common content metadata 1502, common banner data 1503, common content data 1501, and common web link information 1502 are input to the TV gateway 421. These converted data are converted into a common format by the conversion units 1411-1413 for each of the different video platforms 411-413.

[0039] In the first to third embodiments, the definition of mobile terminals 401 to 410 is a network-connected device that includes a camera, and also includes computer terminals such as smartphones, personal computers, laptop computers, and desktop computers.

[0040] In the first to third embodiments, QR codes are displayed on the television receivers 141-150 and 441-450 to facilitate communication between the mobile terminals 401-410 and the television receivers 141-150 and 441-450. However, other types of codes are acceptable. For example, a set of numbers such as a PIN code or a barcode would suffice, as long as the mobile terminals 401-410 can optically detect the address information necessary to connect to the video platform 411 along with the authentication code 611. Furthermore, while the above embodiments use optical detection as an example, any function that enables communication between the mobile terminals 401-410 and the television receivers 141-150 and 441-450 would suffice. For example, the address information necessary to connect to the video platform 411 along with the authentication code 611 could be sent wirelessly or via a wired connection.

[0041] [Note] A gateway device connecting multiple video distribution platforms and multiple cloud systems that connect multiple television receivers. This gateway device is characterized by converting metadata output from different video platforms into common data for content selection. Multiple cloud systems configure screen control data from the common content selection data output from the gateway device, ensuring it is in the optimal format for each connected television, and then configure the content selection screen on the television. The content selection screen consists of banner displays of past and future streaming content, based on information provided by the TV Gateway. The IDs of the TV receiver and the mobile device are linked, and the way the content selection screen is displayed changes depending on the linked ID. For example, channels associated with the distribution platform included in the ID are displayed preferentially. The TV receiver ID consists of the ID of the TV cloud connected to the TV and the device ID representing the TV itself, while the mobile ID consists of the ID of the streaming platform that delivers the video and the user's ID. If multiple mobile IDs are combined into a TV ID, priority will be given to channels from the streaming platform launched from the mobile application associated with the streaming platform included in the mobile ID. When a mobile ID and a TV receiver ID are linked, video content provided by the distribution platform included in the mobile ID will be displayed as recommended content. When a mobile ID and a TV receiver ID are linked, related video content can be viewed via VoD (Video on Demand) from the video content provided by the distribution platform included in the mobile ID. When a mobile ID and a TV receiver ID are linked, related web content will be displayed simultaneously or switched between from the video content provided by the distribution platform included in the mobile ID. When the mobile ID and TV receiver ID are linked, the mobile app plays the associated video content. A gateway device connected to multiple video platforms sorts and analyzes viewing data obtained from televisions using mobile IDs, and then recommends video content or selects inserted advertisements based on the results.
