Detailed Description

Hereinafter, an information integration system according to an embodiment will be described with reference to the drawings. In the following embodiments, the same reference numerals are used to perform the same operations, and overlapping descriptions are appropriately omitted. The following embodiments do not limit the disclosed technology. The embodiments can be appropriately combined within a range where the processing contents are not contradictory.

(embodiment 1)

Fig. 1 is a diagram schematically showing an overall configuration example of the information integration system S according to embodiment 1. The information united system S includes a television apparatus 2 (broadcast receiving apparatus), a TV cloud 3 (server apparatus), a video platform 4, a television gateway 5, and a user information database 6.

The television apparatus 2 can communicate with a mobile terminal (for example, a smart phone) possessed by a user (subscriber to the CSP). A CAS (Conditional Access System: conditional access system) card for utilizing broadcasting of a limited reception scheme is inserted into the television apparatus 2. Stored in the CAS card is: an inherent Identifier (ID) called CAS information; and a key (secret key) for decrypting the encrypted video signal. The CAS information can be associated with an identifier of the television apparatus 2.

In addition, the television apparatus 2 performs the combination of the HA-ID and the MA-ID. Here, HA-ID and MA-ID are abbreviations of Home Agent ID and Mobile Agent ID, respectively. The HA-ID is an identifier that identifies the TV cloud and the television apparatus. The MA-ID is an identifier that identifies the video platform 4 and the user (or a smart phone or the like that the user has), and is a composite identifier.

The TV cloud 3 is a server apparatus capable of transmitting and receiving information to and from the television apparatus 2 via a network, and is a so-called cloud server. The TV cloud 3 may be, for example, a server device used by a manufacturer of the television apparatus 2. The TV cloud 3 provides various services such as recommendation information based on a viewing program, a reserved program, and commodity recommendation information of a viewing program content to the television apparatus 2 via a network based on the result of information (viewing information) on viewing collected from the television apparatus 2.

The video platform 4 is a CSP content providing device that provides contents such as moving images. In addition, the video platform 4 is connected to a user information database 6.

The television gateway 5 is connected to the video platform 4, the TV cloud 3, and the television apparatus 2. The television gateway 5 provides a standard selection method of the dynamic image contents to the television apparatuses 2 with different functions and performances, thereby facilitating the selection of more dynamic image contents without impairing the convenience of the user.

The television gateway 5 further includes a connection information storage unit for storing connection information between the HA-ID and the MA-ID. The television gateway 5 is able to customize the program table based on the HA-ID combined with MA-ID information.

The user information database 6 is connected to the CSP's video platform 4. The user information database 6 associates and manages, for example, MA-IDs, CAS information associated with the television apparatus 2, user contract information (service contract contents, available programs, various conditions, and the like) on a user identifier for specifying a user. Thus, the video platform 4, by accessing the user information database 6, is able to determine the user, for example based on the MA-ID, and confirm the contract content.

The following describes the respective configurations of the television apparatus 2, the TV cloud 3 (server apparatus), the video platform 4, and the television gateway 5.

Next, information combining processing performed by the information combining system S will be described. Here, the information association processing is processing as follows: the CAS information associated with the television apparatus 2 is exchanged for the approval code on the video platform 4 side, and the identifier of the television apparatus 2, the user identifier, and the available service ID information are combined in the television gateway 5.

[ information Combined processing ]

Next, information combining processing performed by the information combining system S will be described. The information syndication processing performed by the information syndication system S simplifies the syndication of the service managed by the CSP side for each user and the information of the TV device on the user side by using the CAS information associated with the television apparatus 2.

Fig. 10 is a sequence diagram showing a flow of information syndication processing performed by the information syndication system S. In the information association process shown in fig. 10, the CAS information associated with the television apparatus 2 is transmitted to the video platform 4, and is set so that a user is given a reservation in advance. In addition, in the case where an offer from the user is obtained, the CAS information is used to acquire the service ID information that can be viewed.

As shown in fig. 10, the television apparatus 2 transmits an authorization code (Authorization Code) issuing request to the TV cloud 3 (step S101).

The TV cloud 3 transmits a code as an authorization code to the television apparatus 2 in response to the authorization code issuance request from the television apparatus 2, and also transmits a response including the state (state) of the random string (step S102).

The television apparatus 2 transmits an OAuth token end point request to the TV cloud 3 (step S103). The TV cloud 3 receives the OAuth token end point request from the television apparatus 2 and transmits an OAuth token end point request including the PF-ID, HA-ID, TC-ID to the television gateway 5 (step S104). Here, the PF-ID is an Identifier (ID) that identifies the video platform. The HA-ID is an identifier that identifies both the television and the TV cloud. The TC-ID is an identifier that identifies the TV cloud.

The television gateway 5 receives the OAuth token endpoint request from the TV cloud 3, and responds to the TV cloud 3 with the OAuth token endpoint including the code (code) and the state (state) (step S105). The TV cloud 3 acquires the OAuth token endpoint from the response from the television gateway 5, and transmits the OAuth token endpoint as a response to the token endpoint request from the television apparatus 2 (step S103) (step S106).

The television apparatus 2 transmits, to the video platform 4, a client ID (client_id), a client key (client_secret), and CAS information associated with the television apparatus 2 issued in advance from the video platform 4 side, and makes a user information inquiry request (step S107). In addition, the CAS card storing the CAS information can be taken to other television apparatuses 2 by plugging in and out. The television apparatus 2 confirms whether the CAS card currently inserted has been registered.

The video platform 4 refers to the user information database 6 in response to the user information inquiry request from the television apparatus 2, and confirms the joining information of the client (step S108). That is, the video platform 4 confirms whether the client included in the user information inquiry request has joined (signed up), and in the case of joining, confirms the service ID that can be viewed.

The video platform 4 associates the CAS information contained in the user information inquiry request with the user identifier (user ID) of the user information database 6. Further, the video platform 4 issues a PS (Pre-Share Code) Code associated with the CAS information to be associated with the user identifier (step S109). Here, the PS code is a random string that corresponds to CAS information one-to-one, and is used to manage CAS information on the video platform 4 side. PS codes are one example of code information.

The video platform 4 transmits a response to the user information inquiry request for step S107 to the television apparatus 2 (step S110). The response contains information (true) or information (false) that the client has joined, information (services) of a service ID that can be viewed in the case of joining, and PS code (string). In addition, information (services) of viewable service IDs is an example of user contract information, such as information of services viewable under contract, information in period-limited free broadcasting.

The television apparatus 2 automatically performs the association using the OAuth token endpoint and PS code (< OAuth token endpoint.

The television gateway 5 transmits a token request to the video platform 4 (step S112). The token request contains the following information.

"client_id"：<client_id>,

"grant_type"："authorization_code"

"code"：<pscode>

"redirect_uri"：<redirect_uri>

The video platform 4 returns the following information about the joined user as a response to the token request from the television gateway 5 (step S113).

"access_token"：<access token>

"token__type"：<token type>

"refresh_token"：<refresh token>

"serviceids": [ viewable serviceids ]

"id_token"：<id token>

On the other hand, errors are reported for the non-joining users.

The television gateway 5 combines or updates the MA-ID with the HA-ID based on the information received in step S113 (step S114). That is, the television gateway 5 combines the identifier of the television apparatus 2, the user identifier, and the available service information based on the information received in step S113.

As described above, the information combining system S according to embodiment 1 includes: a television apparatus 2; a video platform 4 for distributing dynamic image contents; and a television gateway 5 for making a connection for providing the moving image content from the video platform 4 to the television apparatus 2. The television apparatus 2 transmits the 1 st information including the CAS information used in the television apparatus 2 to the video platform 4. The video platform 4 transmits, in response to the 1 st information, the 2 nd information including the PS code as the code information associated with the CAS information to the television apparatus 2. The television apparatus 2 transmits the code information to the television gateway 5 in response to the 2 nd information. The television gateway 5 receives a user identifier from the video platform 4 based on the code information received from the television apparatus 2 and associates the user identifier with the identifier of the television apparatus 2.

Thus, the association between the user identifier and the identifier of the television apparatus 2 can be automatically achieved using the PS code associated with the CAS information. Therefore, in this combination, it is no longer necessary to use a smart phone on the user side to read a two-dimensional barcode displayed on the TV device, input a user identifier and a password registered in advance in a Web page provided by the CSP, and the like. That is, the user needs to make only a job of making a purchase with respect to the use of the CAS information. As a result, the CSP side can combine the service managed for each user with the information of the TV device on the user side by a simpler procedure than before.

For example, when a service subscribed by a user is associated with information of a TV apparatus, from the viewpoint of personal information protection, it is necessary to obtain agreement for the user regarding a service provided by using the associated information and a purpose of use. Even in such a case, the information associating system S according to embodiment 1 can automatically perform association between the user identifier and the identifier of the television apparatus 2 by using the PS code associated with the CAS information.

(embodiment 2)

An information integration system S according to embodiment 2 will be described. The information associating system S according to embodiment 2, for example, transmits a public key to the manufacturer of the television apparatus 2 in advance, and performs identifier association using PS information obtained by encrypting CAS information with the public key. The overall configuration of the information integration system S according to embodiment 2 is the same as that of the example shown in fig. 1.

Fig. 11 is a sequence diagram showing a flow of information syndication processing performed by the information syndication system S. In the information association process shown in fig. 11, the CAS information associated with the television apparatus 2 is transmitted to the video platform 4, and is set so that a user is given a reservation in advance. In addition, in the case where an offer from the user is obtained, the CAS information is used to acquire the service ID information that can be viewed.

In fig. 11, steps S201 to S206 are similar to steps S101 to S106 shown in fig. 10.

The television apparatus 2 encrypts the CAS information associated with itself by using the public key acquired in advance, and generates a PS code (step S207).

The television apparatus 2 automatically performs the association using the OAuth token end point and PS code (< OAuth token end point >.

The television gateway 5 transmits a token request to the video platform 4 (step S209). The token request contains the following information.

"client_id"：<client_id>,

"grant_type"："authorization_code"

"code"：<pscode>

"redirect_uri"：<redirect_uri>

The video platform 4 decodes the encrypted CAS information (i.e., PS code) contained in the token request using the key (step S210). The video platform 4 refers to the user information database 6 using the decoded CAS information, and confirms the joining information of the client (step S211). That is, the video platform 4 confirms whether the client associated with the token request has joined (signed up), and in the case of joining, confirms the service ID that is available for viewing.

The video platform 4 returns the following information about the joined user as a response to the television gateway 5 (step S212).

"access_token"：<access token>

"token__type"：<token type>

"refresh_token"：<refresh token>

"serviceids": [ viewable serviceids ]

"id_token"：<id token>

On the other hand, errors are reported for the non-joining users.

The television gateway 5 combines or updates the MA-ID with the HA-ID based on the information received in step S212 (step S213). That is, the television gateway 5 combines the identifier of the television apparatus 2, the user identifier, and the available service ID information based on the information received in step S212.

The information integration system S according to embodiment 2 described above includes: a television apparatus 2; a video platform 4 for distributing dynamic image contents; and a television gateway 5 for making a connection for providing the television apparatus 2 with the moving image content from the video platform 4. The television apparatus 2 transmits 1 st information to the television gateway 5, the 1 st information including PS codes as code information obtained by encrypting CAS information used in the television apparatus 2. Video platform 4 decodes CAS information in response to a request from television gateway 5 to use the 1 st information, and transmits the user identifier associated with the PS code and the user contract information to television gateway 5. The television gateway 5 receives a user identifier from the video platform 4 based on the PS code received from the television apparatus 2 and associates the user identifier with the identifier of the television apparatus 2.

Thus, the association between the user identifier, the user contract information, and the identifier of the television apparatus 2 can be automatically achieved using the PS code associated with the CAS information. As a result, as in embodiment 1, services managed by the CSP side for each user can be joined with information of the TV device on the user side by a simpler procedure than in the related art.

(embodiment 3)

An information integration system S according to embodiment 3 will be described. The information syndication system S of embodiment 3 is an example of a case where there is no association between a user identifier and CAS information on the video platform 4 side.

Fig. 12 is a diagram schematically showing an overall configuration example of the information united system S according to embodiment 3. In comparison with the information integration system S of embodiment 1, the information integration system S of embodiment 3 further includes a smartphone 1 (terminal).

The smartphone 1 is an example of an information terminal that the user of the television apparatus 2 has. The smart phone 1 includes a communication I/F (interface), a sound input unit (microphone), a sensor group, a display unit, a graphics controller, a touch panel controller, a CPU (Central Processing Unit: central processing unit), a memory, a camera, a speaker, and the like. The smartphone 1 is capable of wireless communication with the video platform 4, TV cloud 3 via a base station.

Fig. 13 is a sequence diagram showing a flow of information syndication processing performed by the information syndication system S. In the information association process shown in fig. 13, the CAS information associated with the television apparatus 2 is also set to be previously offered from the user for delivery to the video platform 4. The television apparatus 2 is set to acquire the PS code by the information combining process shown in fig. 10 and 11.

In fig. 13, steps S301 to S306 are similar to steps S101 to S106 shown in fig. 10.

The television apparatus 2 generates a two-dimensional bar code including the OAuth token end point acquired in step S306 and the PS code acquired separately, and displays the two-dimensional bar code on, for example, a screen (step S307).

The smartphone 1 reads the two-dimensional barcode displayed on the television apparatus 2, performs Web access to the television gateway 5, and automatically performs association using the OAuth token endpoint and the PS code (step S308).

The television gateway 5 sends a token request to the video platform 4 (step S309). The token request contains the following information.

"client_id"：<client_id>,

"grant_type"："authorization

"code"：<pscode>

"redirect_uri"：<redirect_uri>

The smartphone 1 performs member registration and registration on the video platform 4 by Web access (steps S310 and S311).

The video platform 4 associates and registers the user identifier, the joining information, the CAS information with the user information database 6 in response to the access from the smartphone 1 (step S312).

The video platform 4 returns the following information about the joined user as a response to the television gateway 5 (step S313).

"access_token"：<access token>

"token__type"：<token type>

"refresh_token"：<refresh token>

"serviceids": [ viewable serviceids ]

"id_token"：<id token>

On the other hand, errors are reported for the non-joining users.

The television gateway 5 combines or updates the MA-ID with the HA-ID based on the information received in step S313 (step S314). That is, the television gateway 5 combines the identifier of the television apparatus 2, the user identifier, and the available service ID information based on the information received in step S313.

According to the information associating system S of embodiment 3 described above, even when there is no association between the user identifier and the CAS information on the video platform 4 side, association between the user identifier and the identifier of the television apparatus 2 can be achieved by using the PS code associated with the CAS information. As a result, as in embodiment 1, services managed by the CSP side for each user can be joined with information of the TV device on the user side by a simpler procedure than in the conventional one.

Fig. 14 is a flowchart showing a flow of processing until the program table is displayed, including the information association processing of any one of embodiments 1 to 3.

As shown in fig. 14, CAS information is displayed on the screen of the smartphone 1 using an offer screen (step SA 1). By this display, a query is made to the user side as to whether or not to offer the use of CAS information.

The user makes a response of whether or not to offer the CAS information utilization via the CAS information utilization offer screen displayed on the screen of the smartphone 1 (step SA 2).

When the user makes a decision for the use of CAS information (yes in step SA 2), the information association processing of any one of embodiments 1 and 2 is executed (step SA 3).

The information association processing of step SA3 is performed, and as a result, on the video platform 4 side, it is determined whether the CAS information has been associated with the service identifier of the user (step SA 4).

When it is determined that the CAS information and the service identifier of the user are not associated (no in step SA 4), an ID association screen and a two-dimensional barcode are displayed on the screen of the television apparatus 2, and the information association process according to embodiment 3 is executed. That is, since the CAS information and the user identifier are not yet associated on the video platform 4 side, the user is guided to the user identifier and service identifier registration (new creation) by the information association process of embodiment 3 (step SA 5).

On the other hand, when it is determined that the CAS information is associated with the service identifier of the user (yes in step SA 4), the television apparatus 2 requests and acquires a viewable service (content) from the TV cloud 3 and the television gateway 5 (step SA 6).

In addition, when the user does not offer the CAS information utilization (no in step SA 2), the television apparatus 2 acquires the service (content) that is currently available (step SA 6).

The television apparatus 2 generates and displays a program table corresponding to the content acquired in step SA6 (step SA 7).
