Description

Technical Field

[0001] The present invention relates to a server system for delivering video, a receiving terminal for receiving video that receives video content, and a gateway device located therebetween.

Background Art

[0002] In recent years, with the evolution of the network, 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 the network and play the videos distributed, enabling users to enjoy higher-quality and more immersive videos. This has become possible due to the high-speed 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 sophisticated, and not only simple video viewing, but also so-called interactive services that link video and Web information, such as guiding from video content to an EC (electronic commerce) site to purchase goods and checking details in video from Web information on the Internet (such as news and ticket information), are being developed.

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

Summary of the Invention

Problems to be Solved by the Invention

[0006] With the evolution of the network, video distribution services have become easier to implement than before. However, there are various problems in receiving network video distribution services on a television receiver, and it has not reached the level of reception popularity like broadcasting. Furthermore, currently, on information terminals such as PCs, more advanced network services are being implemented through the linkage between the distributed video and web content. However, in conventional television receivers, it has been difficult to realize such linkage services.

[0007] While video content is broadcast according to a unified standard for terrestrial broadcasting, video content over the network is distributed by multiple distribution methods. Therefore, in order to select and receive video content distributed from a video platform that distributes a specific video, it was necessary to equip the receiver side with special functions. Also, in order to receive video content distributed to a television broadcast receiver, a function to connect to the network and the performance to play back the received video content are required of the television receiver.

[0008] Depending on the functions and performance on the television receiver side, there are distributed video contents that can be received and those that cannot be received. For this reason, the video platform and the receiving terminal that realize the conventional video distribution service have been realized by installing their own distribution technologies respectively. From the perspective of the video platform, it is necessary to individually respond to multiple receiving terminals with different performances and functions. From the perspective of the receiving terminal, it is necessary to individually respond to video platforms with multiple different distribution methods. Also, there are various methods when selecting video content, and a consistent program selection method cannot be provided, which causes confusion to users. Such a situation not only hinders the popularization of video distribution but also poses a major problem from the perspective of user convenience.

[0009] On the one hand, when providing interactive services by linking video content and web content with each other, since the operation of the television receiver is performed by a remote control, its operability is extremely poor compared to the input functions such as the keyboard and mouse of information terminals such as PCs, and it has been difficult for users to operate comfortably and receive advanced services. Since such advanced services are implemented by the cooperation of the video platform and the website, it is difficult to commonly provide such linked services with television receivers of different video platforms and different functions and performances.

[0010] FIG. 16 shows a configuration diagram of a conventional video distribution system. In FIG. 16, CSPs (Content Service Providers) 101 to 108 provide video content. The video content is input to video platforms 1611 to 1613 respectively. The video platforms 1611 to 1613 send video streams to television receivers 141 to 150. Since each video platform has a different distribution method, each video stream is received only by limited television receivers. In this conventional example, the video platform 1611 can be received by the television receivers 141 to 143, the video platform 1612 can be received by the television receivers 144 to 147, and the video platform 1613 can be received by the television receivers 148 to 150. It is difficult to widely and commonly distribute video content to television receivers with different functions. Also, when the website 1601 connected to the video platform 1613 and the video output from the video platform 1613 are interlocked to provide services, the functions of the remote control of a normal television receiver are limited to up, down, left, right, numeric buttons, etc., which has imposed a great burden on the user's operation.

[0011] Using FIG. 17, the operation of selecting video content from a conventional video distribution system will be described. For example, since the television receivers 144 to 147 in FIG. 16 receive from both the video platforms 1612 and 1613, as shown in 1701, the user first selects from the platform selection screen 1701, the video platform button 1702, and the video platform button 1703. Each button is configured on the television receiver side by the video platform selection metadata 1712 and 1722 provided from each video platform. When any button is pressed, the content selection screen 1710 is advanced, and the content is selected by pressing the buttons 1711 to 1716 of the content. These buttons are generated by the content metadata 1723 provided from the video platform. Such a selection operation is performed by the television remote control 1731.

[0012] Furthermore, after the content is selected, when the video content and the web content are linked, for example, when the video content 1741 and the web content 1742 are simultaneously displayed, a more complex operation is required, and with the television remote control 1731, the operation load on the user becomes large. Therefore, there are restrictions on the expression of the content.

Means for Solving the Problem

[0013] In a system for providing a content distribution service from a content service provider to a television receiver, a television gateway is provided. The television gateway receives information including content information from a video platform that aggregates and distributes content information from the content service provider, and converts the received content information so that the information can be received by the television receiver.

Effect of the Invention

[0014] With this configuration, each video platform can input to the TV gateway without worrying about TV receivers with different performances and functions, and can present content to all TV receivers with a single format of input. Furthermore, by linking the TV receiver with a mobile terminal represented by a smartphone, instead of using single-function remote controls with different operability, using a mobile terminal can achieve improved operability for advanced services. Moreover, it is possible to perform advanced linkage operations between a smartphone and a TV that cannot be done with existing remote controls. At that time, by combining the ID of the TV receiver and the ID of the mobile terminal, the convenience of the user is greatly improved, such as automatically presenting the services of the website linked to each video platform.

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., which are web content provided in conjunction with the video content. The system is composed of a video platform with different functions and a television receiver with different functions and performances. In such a system environment, the present invention implements a good video viewing environment and, furthermore, an advanced service that links video and web content.

[0017] In the present invention, these problems are solved by installing a television gateway and linking a mobile terminal and a television receiver. Furthermore, in the present invention, content from different video platforms is once received by a TV gateway. Further, the output from the TV gateway is input to a TV cloud connected to a TV having substantially the same performance and substantially the same functions. Here, the TV gateway converts the input from the video platform into a format that can be commonly provided to the TV cloud. Further, the TV cloud generates a screen data configuration selectable on the TV under the management of the connection destination, and forms an optimal content selection screen on each TV receiver.

[0018] (First Embodiment) A first example according to the present invention is shown in FIG. 1. Different from the conventional video distribution system, the TV gateway 121 and the TV clouds 131 to 134 are located between the video platforms 111 to 113 and the TV receivers 141 to 150. The video content provided by the CSPs 101 to 108 and the information for content selection are input to the TV gateway 121 by the video platforms 111 to 113, respectively. After converting the information for selecting a predetermined video content, the TV gateway 121 inputs it to the TV clouds 131 to 134. The TV clouds 131 to 134 convert the information input to each of the TV clouds 131 to 134 from the TV gateway 121 into data for the TV receiver to configure a screen for content selection.

[0019] The TV cloud 131 generates and transmits content selection screen data to the TV receiver groups 141 to 143 having substantially the same functions and under connection and management. Similarly, the TV cloud 132 outputs to the TV receiver groups 144 to 145, the TV cloud 133 outputs to the TV receiver groups 146 to 147, and the TV cloud 134 outputs to the TV receiver groups 148 to 150. Each of these TV receiver groups is managed as a block having substantially the same functions and performance. Here, the TV clouds 131 to 134 have information on the TV functions and performance of their respective connection destinations, generate selection screen data for receivable content for the TV receiver, and each TV receiver configures the optimal screen based on that data. Through the above operations, it becomes possible to commonly select video content provided from different video platforms with TV receivers having different functions.

[0020] Next, the details of the operation of this system will be described. FIG. 2 shows an example of the program selection screen provided according to this embodiment. From the video platforms 111 to 113, the time table 201, content metadata 202, and banner data 203, which are information for content selection, are provided to the TV gateway 121. These data are dependent on the video platforms 111 to 113 and are in different formats. Next, the TV gateway 121 converts the time table 201, content metadata 202, and banner data 203 into common content selection data 204 in order to supply them to each of the TV clouds 131 to 134. Here, the content selection data 204 includes a time table for arranging banners, channel numbers, and metadata explaining the content of the content.

[0021] From the TV gateway 121, the TV clouds 131 to 134 that have received the content selection data 204 generate content selection screen data 210 according to the functions and performances of the respective TV receivers. At this time, the video content provided by the video platforms 111 to 113 is assigned to single or multiple channels, and the user can select the video content without being aware of the differences between the video platforms. Such a screen is finally composed by the browser of the TV receiver based on the content selection screen data 210. Here, the metadata includes video and audio format information, and by comparing it with the information on the functions and performances of the TV receiver, it is determined whether playback is possible. The information on the TV receiver functions and performances is held by each TV cloud, and the programs with additional playback are grayed out on the content selection screen.

[0022] The details of the above operations are shown in FIG. 3. The video platforms 111 to 113 provide data sets 301 to 303 of the time table, content metadata, and banner data to the TV gateway 121. Here, the data sets 301, 302, and 303 are not guaranteed to be mutually compatible and are provided in different formats. The TV gateway 121 converts these data sets into common content selection data 204. Each TV cloud 131 to 134 receives the content selection data 204 provided by the TV gateway 121, and in each TV cloud, content selection screen data 341 and 344 are generated. Here, as an example, TV cloud 131 and TV cloud 134 are shown. For example, TV cloud 131 generates content selection screen data 341 for the connected TV receivers 141 to 143, and TV cloud 134 generates content selection screen data 344 for the connected TV receivers 141 to 150. Each TV receiver presents a screen based on this data.

[0023] (Second Embodiment) FIG. 4 shows a second example according to the present invention. This embodiment adds mobile terminals 401 to 410, a viewing data storage unit 451, an ID combination information storage unit 452, a content recommendation information storage unit 453, a recommended advertisement selection and insertion unit 454, and an advertisement server 455 to the first embodiment. In this embodiment, until the generation of the content selection screen, the same operations as in the first embodiment are performed, but the TV receivers 441 to 450 and the mobile terminals 401 to 410 are connected by the IDs (individual identification data) they each have. Also, each of the TV receivers 441 to 450 has a function of measuring what the user is viewing as viewing data, and the measured viewing data is uploaded to the TV gateway 421 through the TV clouds 431 to 434.

[0024] The viewing data storage unit 451 and the ID combination information storage unit 452 are combined with the TV gateway 421. The viewing data obtained from the TV receivers 441 to 450 is stored in the viewing data storage unit 451 via the TV clouds 431 to 434 and the TV gateway 421. Also, the combination information of the IDs of the TV receivers 441 to 450 and the mobile terminals 401 to 410 is supplemented in the ID combination information storage unit 452. The content recommendation information storage unit 453 calculates, based on the information in the viewing data storage unit 451 and the ID combination information storage unit 452, which TV receivers have a viewing tendency for what kind of content, and conveys it to the video platforms 411 to 413. This calculation is realized by measuring the viewing time of the genre of each content viewed, etc.

[0025] On the other hand, the recommended advertisement selection and insertion unit 454 calculates, from the viewing data storage unit 451 and the ID combination information storage unit 452, which TV receivers should insert what kind of advertisement, acquires a desirable advertisement from the advertisement server 455, and inserts the advertisement into the video content of the video platforms 411 to 413.

[0026] An example of the configuration combined with the ID in the present invention is shown in FIG. 5. Mobile terminals 401 to 410 have SP-IDs (smartphone IDs) 501. On the other hand, television receivers 441 to 450 have TV-IDs (television IDs) 511. The SP-ID is composed of a PF-ID which is an ID of the video platform and a UR-ID which is a user ID. The TV-ID is composed of a TC-ID which is an ID of the television cloud and a DV-ID which represents the television receiver itself as a device. In the ID combination information storage unit 452, a table 520 showing the combination information of the SP-ID and the TV-ID is configured, and the television receiver and the mobile terminal form a connection state by the ID. Here, in table 520, "〇" indicates the connected state, and "―" indicates the unconnected state. Here, a plurality of mobile terminals may be connected to one television receiver.

[0027] FIG. 6 shows the ID combination method and the data stored in each. The television receiver 141 and the mobile terminal 401 such as a smartphone transmit an authentication code 611 to the mobile terminal 401 by a QR code (registered trademark) or the like displayed on the television receiver. The correspondence table between this authentication code and the television is stored in advance in the television ID storage unit 603 of the television cloud 431. The authentication code 611 is an authentication code with a time limit corresponding to the TV-ID individually assigned to the television receiver 141. This authentication code 611 is sent from the television cloud 431 to the television receiver 141. At this time, the television cloud 431 adds address information for connecting to the video platform 411 together with the authentication code 611 and sends it to the mobile terminal 401.

[0028] The authentication code 611 is sent as data 612 together with the SP-ID of the mobile terminal from the smartphone 401 to the video platform 411. The video platform 411 acquires the user attributes from the customer data storage unit 601 it owns based on the acquired authentication code 611 and the SP-ID of the associated mobile terminal 401, and combines the SP-ID and sends it as data 613 to the television gateway 421. After the TV gateway obtains the authentication code, SP-ID, and user attributes as data 613, it queries the TV cloud 431 based on the authentication code to obtain the corresponding TV-ID. Here, the TV cloud 431 manages the TV-ID of the TV receivers under its control, has a correspondence table of TV-ID and authentication code in the TV ID storage unit 602, and obtains from the authentication code which TV receiver has become the target of connection. The authentication code arranged 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, the combination information of the TV-ID and SP-ID is notified to the video platform 411 by the pass key 621. The pass key 621 serves as the key of the database in the ID combination information storage unit 602. By sending the pass key 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 TV receiver are connected by the ID. After the ID combination, the video platform 411 can subsequently deploy services to the target TV receiver by the pass key 621 transferred from the TV gateway 421. Note that the pass key 621 is stored in the customer data storage unit 601 so that the correspondence with the SP-ID can be known. Although the sixth figure has been described for the case of the video platform 411, the same operations are also performed in the video platforms 412 and 413.

[0029] The selection screen of the content when the IDs are combined is shown in the seventh figure. When the TV-ID and the SP-ID are in a combined state, the PF-ID, which is a component of the SP-ID, enables the identification of the video platform to which the viewing user belongs. Therefore, on the content selection screen, channels composed of the corresponding video platform are presented at easily accessible positions. For example, in the case of Fig. 7, when the SP-ID 501 includes the ID of the video platform 411, presenting the channels provided by the video platform 411 as the initial screen facilitates user selection. Also, by inferring the viewing tendency from the viewing data of the TV receiver specified by the TV-ID, recommended contents 701, 702, and 703 are simultaneously displayed. In this way, due to the combination of the IDs, by preferentially presenting the content of the corresponding video platform to the user, the service provided by the video platform can be easily obtained.

[0030] Fig. 8 shows an example of the display of a screen in which video content and web services are linked. When the TV-ID 511 and the SP-ID 501 are in a combined state, the web service screen linked to the video platform indicated by the SP-ID 501 is automatically displayed on the TV receiver indicated by the TV-ID. As a result, the user can receive services such as related information and product descriptions on the EC site in addition to video viewing. Also, the mobile app 812 and the video screen 811 displayed on the mobile terminal can be linked, enabling a video content selection method that is not possible with a normal remote control. For example, by touching interesting news on the news site of the mobile app on the mobile terminal, the related video content can be played on the TV receiver, enabling unprecedented content selection. On the other hand, by displaying the EC site on the mobile app and tapping an interesting product, a user experience that has never been available before, such as viewing a detailed product description by video, can be obtained.

[0031] The above operations will be described in detail with reference to Fig. 9. When the video content of the video platform 411 is linked to the website 901, the web link information 902 is input from the video platform 411 to the TV gateway 421. In addition to the conventional time table 201, content metadata 202, and banner data 203, the recommended content data 901 is input to the TV gateway 421. The TV gateway 421 transfers the combined TV-ID 501, content selection data 204, the recommended metadata 911 created from the recommended content data 901, and the linked destination URL obtained from the web link information to the TV cloud 431. The TV cloud 431 generates the recommended content display data 914 on the content selection screen and sends it to the TV receiver 441. At that time, the linked destination URL is set to the TV receiver 441 together with the channel and time information so that the video content can be linked. The TV receiver 441 displays the web content indicated by the linked destination URL on the TV screen when the user presses a link button or the like based on a specific channel and the viewing time zone.

[0032] When linked with the mobile app, after downloading the mobile app from the website 901 to the mobile terminal 401, the operation result of the mobile app and the SP-ID are sent to the video platform 411. Then, by sending the pass key and the mobile operation from the video platform 411 to the TV gateway 421, it is converted into the common TV operation code 903, and further converted into the TV operation code by the TV cloud 431 to control the TV receiver 441. The pass key is obtained from the customer data storage unit 601, which is a correspondence table with the SP-ID. The above has been described with respect to the video platform 411, but the same operation applies to other video platforms. Also, the same operation applies to TV clouds other than the TV cloud 411 and TV receivers other than the TV receiver 441.

[0033] FIG. 10 shows the explanation of the recommendation of content and the insertion of advertisements according to the present invention. The information of the viewing data storage unit 451 and the ID combination information storage unit 452 is input into the content recommendation information storage unit 453, which calculates the viewing tendency of the TV and determines recommended content and candidates for desirable advertisements. Based on the information in the content recommendation information storage unit 453, the recommended advertisements are obtained from the advertisement server 455, and the video platform 411 inserts the advertisements into the video content according to the output of the recommended advertisement selection and insertion unit 454. On the other hand, in the receiving-side advertisement insertion unit, based on the information in the content recommendation information storage unit 453, desirable advertisements are transferred from the advertisement server 455, and the receiving-side advertisement insertion unit 456 outputs to insert the advertisements into the operating content on the TV receiver 141. For example, when the video platform 411 distributes video by the multicast method, it is not possible to insert individual advertisements for each TV receiver. In this case, first, the video platform 411 inserts advertisements and distributes common advertisements, and then the TV receiver side individually overwrites the desirable advertisements. By this operation, it is possible to present advertisements suitable for users such as targeted advertisements to individual TV receivers.

[0034] FIG. 11 shows a configuration diagram of a TV receiver according to the present invention. The broadcast is received by the antenna 1101, and the broadcast content converted into a digital stream by the tuner 1102 is converted into an audio signal and a video signal by the signal processing unit 1103. The audio signal is processed by the audio processing unit 1104, and the audio is reproduced by the speaker 1106. Also, the video signal is processed by the video processing unit 1105, and the video is reproduced 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. The user's operation is input from the remote control 1113 to the receiving unit 1112 and then input to the control program. The communication interface 1111 receives video content and a content selection screen distributed from the network and processes them with the control program of the CPU 1109.

[0035] FIG. 12 shows a configuration diagram of a video platform according to the present invention. The CPU 1202 is connected to the memory 1201 and the storage device 1203, and executes a control program. The operation unit 1205 controls the operation by the operator. The communication interface 1204 is connected to the network, and performs input / output of video content, distribution of video, and input / output of content selection information. Note that the video processing unit 1206 generates a stream for video distribution without encrypting the input video content.

[0036] FIG. 13 shows a configuration diagram of a TV gateway according to the present invention. The CPU 1302 is connected to the memory 1301 and the storage device 1303, and a predetermined processing program operates. The interface 1304 performs input / output from / to the video platform and input / output to / from the TV cloud. Note that the operator controls the operation by the operation unit 1305.

[0037] (Third Embodiment) FIG. 14 shows a configuration diagram of a third example according to the present invention. The difference from the second example is that conversion units 1411 to 1413 are inserted between the video platforms 411 to 413 and the TV gateway 1412. In this example, different data output from different video platforms 411 to 413 is converted into common data by the converters 1411 to 1413 in advance and input to the TV gateway 1412. By this process, since the TV gateway 1412 processes common data, the processing load can be reduced. These conversion units 1411 to 1413 may be provided inside the TV gateway 1412 as an input interface of the TV gateway 1412, or may be provided inside the video platforms 411 to 413 as an output interface of the video platforms 411 to 413. In the second embodiment, different data was directly input from the video platforms 411 to 413 and converted into common data internally, while in the third embodiment, the conversion to common data is requested from each of the video platforms 411 to 413. As a result, the load can be dispersed.

[0038] FIG. 15 shows an operation explanatory diagram of a third embodiment according to the present invention. What is different from the operation explanation of the second embodiment shown in FIG. 9 is the point where the conversion unit 1411 is inserted. By the conversion unit 1411, data conversion is performed, and the common time table 1501, the common content metadata 1502, the common banner data 1503, the common content data 1501, and the common web link information 1502 are input to the TV gateway 421. These converted data become data in a common format by the conversion units 1411 to 1413 for any of the different video platforms 411 to 413.

[0039] The definitions of the mobile terminals 401 to 410 in the first to third embodiments include a camera and are devices capable of network connection, and also include computer terminals such as smartphones, personal computers, laptop computers, and desktop computers.

[0040] For the cooperation between the mobile terminals 401 to 410 and the television receivers 141 to 150, 441 to 450 in the first to third embodiments, QR codes are displayed on the television receivers 141 to 150, 441 to 450, but other codes may be used instead. For example, a group of numbers such as a PIN code, or address information for connecting to the video platform 411 together with the authentication code 611 that can be optically detected by the mobile terminals 401 to 410, such as a barcode, may be used. Further, in the above embodiments, an example of optical detection has been given, but any function that enables cooperation between the mobile terminals 401 to 410 and the television receivers 141 to 150, 441 to 450 may be used. For example, address information for connecting to the video platform 411 together with the authentication code 611 may be sent by wireless connection or wired connection.

[0041] [Appendix] · A gateway device connecting a plurality of video distribution platforms and a plurality of cloud systems connected to a plurality of television receivers. This gateway device is characterized by converting metadata output from different video platforms (video distribution platforms) into data for common content selection. A plurality of cloud systems configure screen control data so that the data for common content selection output from the gateway device is in the optimal form for each connected television, and a content selection screen is configured on the television. The content selection screen is composed of banner displays of past and future distributed content based on information provided by the television gateway. The IDs of the television receiver and the mobile terminal are combined, and the combined ID is used to change the display method of the content selection screen. For example, channels related to the distribution platform included in the ID are preferentially displayed. The ID of the television receiver is composed of the ID of the television cloud connected to the television and the ID of the device representing the television main body, and the mobile ID is composed of the distribution platform ID for distributing videos and the user ID. When multiple mobile IDs are combined with a TV ID, prioritize the channels of the distribution platform launched from the mobile application related to the distribution platform included in the mobile ID. When the mobile ID and the TV receiver ID are in a combined state, display the video content provided from the distribution platform included in the mobile ID as recommended content. When the mobile ID and the TV receiver ID are in a combined state, make related video content available for VoD viewing from the video content provided by the distribution platform included in the mobile ID. When the mobile ID and the TV receiver ID are in a combined state, simultaneously display or switch the display of related web content from the video content provided by the distribution platform included in the mobile ID. When the mobile ID and the TV receiver ID are in a combined state, play related video content from the mobile app. A gateway device connected to multiple video platforms sorts and analyzes the viewing data obtained from the TV by the mobile ID, and recommends video content or selects inserted advertisements according to the results.
