[User Authentication]
The timing of user authentication of the content distribution service and an example of communication procedure are as follows. When user authentication is performed when logging in to the content distribution service, it is as follows. The user's display device 1 accesses the content distribution service for login based on the user's operation. The content distribution server 7 transmits a user authentication information request to the display device 1 for user authentication at the time of login. Upon receiving the user authentication information request, the display device 1 transmits the user authentication information including the account information to the content distribution server 7. When the content distribution server 7 receives the user authentication information, it compares and collates with the registered user authentication information and performs user authentication. If the result of the user authentication is successful, the content distribution server 7 responds to the effect that login is permitted, and if it fails, Responds that login is not permitted.

A content viewing portal screen may be provided to a user's device that is a user-authenticated legitimate user. The display device 1 displays the portal screen based on the communication with the content distribution server 7. The portal screen includes content list information and the like. The user can select and search the content to be viewed on the portal screen. The user can view the content without user authentication in the logged-in state. The display device 1 transmits a content reproduction request including the content ID of the content selected by the user to the content distribution server 7. When the content distribution server 7 receives the content reproduction request, the content distribution server 7 distributes the specified content.

When user authentication is performed for each content, it is as follows. The user's display device 1 transmits a content reproduction request including the content ID of the content selected by the user on the portal screen or the like to the content distribution server 7. The content distribution server 7 transmits a user authentication information request to the display device 1 for user authentication for each content. Upon receiving the user authentication information request, the display device 1 transmits the user authentication information including the account information to the content distribution server 7. The content distribution server 7 similarly authenticates the user, and if the result of the user authentication is successful, it responds to the effect that the content reproduction is permitted, distributes the specified content, and if it fails, the content reproduction is not performed. Respond to the effect of permission. The content playback request and user authentication information may be sent together.

[Initial setting]
The operation and processing at the time of initial setting regarding the account information in the first embodiment will be described with reference to FIG. 5 and the like. Here, the initial setting is a setting necessary for the user to enable viewing of the content on the display device 1 in the system of FIG.

[Operation sequence]
FIG. 5 shows an example of an operation sequence between devices at the time of initial setting in the first embodiment. In FIG. 5, the plurality of display devices 1 have the same function including the account information sharing unit 45. In the example of FIG. 5, the mobile terminal 2 of the user U1 is connected to a certain display device 1a in the home network 5, and the account information 101 is transferred and registered. Then, the account information 101 is shared and made available to the plurality of display devices 1a to 1n of the home network 5. The initial setting of FIG. 5 includes an operation until the account information 101 possessed by the mobile terminal 2 is registered as shared account information in a plurality of display devices 1 of the home network 5. FIG. 5 has steps S1 to S9. Hereinafter, the steps will be described in order.

(S1) The mobile terminal 2 of the user U1 is connected to any display device 1 of the home network 5, for example, the display device 1a by wireless connection or the like. The display device 1a to which the mobile terminal 2 is connected in this way is also referred to as a "first device" for the sake of explanation.

(S2) The account information sharing unit 45 of the display device 1a, which is the first device, communicates with the mobile terminal 2 and transfers the account information 101 held in the mobile terminal 2 to the display device 1a for acquisition. At the time of this transfer, the first device may request the mobile terminal 2 to transfer, or the mobile terminal 2 may instruct the first device to transfer. In addition, the user may perform an input operation corresponding to the initial setting on the mobile terminal 2 or the display device 1. The mobile terminal 2 or the display device 1 may transfer the account information in response to the input operation.

(S3) The account information sharing unit 45 of the display device 1a, which is the first device, converts the account information 101 acquired from the mobile terminal 2 into the account information 504 of the user authentication information 503 in its own storage 26, and the shared account information. Register as.

(S4) On the other hand, another display device 1 of the home network 5, for example, the display device 1b does not have account information on its own at the time of initial setting. For the sake of explanation, another display device 1 such as the display devices 1b to 1n is also referred to as a "second device". The account information sharing unit 45 of the display device 1b, which is the second device, inquires about the account information to another display device 1 of the home network 5, for example, the display device 1a. This inquiry is an inquiry as to whether or not the account information is possessed, and is an inquiry including a forwarding request when the account information is possessed.

(S5) The display device 1a, which is the first device, responds when it receives an inquiry from the display device 1b, which is the second device. The account information sharing unit 45 of the first device reads the account information registered as shared account information in its own storage 26, and displays the information including the account information as the display device 1b which is the second device of the inquiry source. Transfer to.

(S6) When the inquiry source display device 1b receives the information including the account information transferred as a response from the inquiry destination display device 1a, the inquiry source display device 1b uses the account information as the account information of the user authentication information 503 in its own storage 26. Register in 504 as shared account information. As a result, the account information is also held in the display device 1b. In the display device 1n or the like, which is another display device 1, the above operation is performed in the same manner, and the same account information is held in each display device 1. As a result, the initial setting is completed. The above operation is the same regardless of which of the plurality of display devices 1 becomes the first device or the second device. For example, when the mobile terminal 2 is first connected to the display device 1b, the display device 1b becomes the first device and the other display device 1 becomes the second device.

(S7) After that, when the user authentication is performed with the content distribution server 7, the display device 1a, which is the first device, uses the account information registered in S3 by the user authentication unit 44. Then, processing related to user authentication can be performed.

(S8) After that, it is assumed that the mobile terminal 2 of the user U1 is connected to the display device 1b, which is the second device. In this case, since the account information is already registered in the display device 1b in S6, it is not necessary to transfer the account information from the mobile terminal 2 to the display device 1b, and the account registration process is unnecessary.

(S9) In the display device 1b, which is the second device, when the user authentication is performed with the content distribution server 7 as in the display device 1a, the user authentication unit 44 has already registered with itself in S6. It is possible to perform processing related to user authentication by using the account information of.

[Processing flow (1)]
FIG. 6 shows a processing flow at the time of initial setting in the display device 1 of the first embodiment. FIG. 6A shows a flow of the first process corresponding to the “first device” of FIG. FIG. 6B shows a second processing flow corresponding to the “second device” of FIG. FIG. 6A has steps S101 to S105. Hereinafter, the steps will be described in order.

(S101) The first device is connected to the mobile terminal 2.

(S102) The account information sharing unit 45 requests the mobile terminal 2 to transfer the account information possessed by the mobile terminal 2, whereby the account information is transferred from the mobile terminal 2 to the display device 1. The account information sharing unit 45 receives and acquires the transferred account information.

(S103) The account information sharing unit 45 registers the account information obtained in S102 in the account information 504 of the user authentication information 503 in the storage 26 as shared account information. At this time, the account information may be passed from the account information sharing unit 45 to the user authentication unit 44, and the user authentication unit 44 may register the account information.

(S104) The account information sharing unit 45 is waiting for an inquiry from a second device which is another display device 1 of the home network 5. When the account information sharing unit 45 receives an inquiry from the second device (S104-Y), the account information sharing unit 45 proceeds to S105.

(S105) In response to an inquiry from the second device, the account information sharing unit 45 determines whether or not there is no problem in providing the account information to the second device. After confirming that there is no problem, the account information sharing unit 45 reads out the shared account information held in the account information 504 in the storage 26, and inquires about the information including the account information via the home network 5 of the inquiry source. Transfer to 2 devices.

FIG. 6B has steps S111 to S115. Hereinafter, the steps will be described in order.

(S111) The account information sharing unit 45 of the second device confirms whether the account information is held in the account information 504 in its own storage 26, that is, whether the shared account information has been registered. If it is possessed (S111-Y), the initial setting process is completed, and if it is not possessed (S111-N), the process proceeds to S112.

(S112) The account information sharing unit 45 confirms whether another display device 1 is connected in the home network 5. If the connection and its display device 1 are known in advance, this step can be omitted. If another display device 1 is connected (S112-Y), the process proceeds to S113, and if it is not connected (S112-N), the process ends.

(S113) The account information sharing unit 45 transmits inquiries about account information to another display device 1 in the home network 5 via the home network 5. The other display device 1 of the inquiry destination may be a first device or a second device.

(S114) The account information sharing unit 45 proceeds to S115 when the account information is transferred as a response from the first device (S114-Y). If not transferred, the other display device 1 of the inquiry is the second device that does not have the account information. The account information sharing unit 45 makes an inquiry in the same manner when there is another display device 1, and ends the process when the account information is not transferred from any of the display devices 1 (S114-N). ..

(S115) The account information sharing unit 45 registers the account information received from the first device in the account information 504 of the user authentication information 503 in its own storage 26 as shared account information. This completes the initial setting process.

As a modification, the account information possession confirmation and the transfer request in the inquiry of S113 may be separated as separate communication steps. Further, at the time of inquiry, the second device may execute the inquiry to all the other display devices 1 of the home network 5 in the same manner, or may execute the inquiry to the specific display device 1. For example, if the first device in the home network 5 is known in advance, the account information sharing unit 45 may send a transfer request only to the first device. Further, when the account information is transferred between the display devices 1, the account information may be encrypted or the like.

The account information sharing unit 45 may manage information on the holding and sharing status of account information in a plurality of display devices 1 of the home network 5 in a table. For example, for each account information, information such as the device ID of each display device 1, the presence / absence of account information possession, and the role may be managed in the table. The role is a first device, a second device, and the like.

[Effects, etc.]
As described above, according to the content viewing system of the first embodiment, the user transfers the account information to the plurality of display devices 1 of the home network 5 while ensuring the control of the content viewing authority using the account information. The time and effort for setting can be reduced, and it is easy to use and highly convenient in various environments and situations.

For example, the user only needs to register the account information possessed by the mobile terminal 2 in the first device, which is one display device 1 of the home network 5, in the initial setting. As a result, the account information is automatically registered on the plurality of display devices 1 of the home network 5 and can be shared and used. It is not necessary to register the account information for each individual display device 1 of the home network 5, which saves the user time and effort.

The conventional technology is not a technology that considers the cooperation between the mobile terminal and the display device, and even if the mobile terminal has the account information, it is easy to share the account information with a plurality of display devices of the home network. is not it. On the other hand, according to the first embodiment, such sharing can be easily realized by a simple operation.

The following can be mentioned as a modification of the first embodiment. For example, first, it is assumed that there are a first television and a second television as a plurality of display devices 1 of the home network 5. It is assumed that the account information of the mobile terminal 2 is already registered in the first television. Suppose a third TV is newly added to the house. When the account information sharing unit 45 of the third television is connected to the home network 5, it makes an inquiry to another display device 1 of the home network 5, for example, the first television, for its own initial setting. The first television that receives the inquiry transfers the account information to the third television. The third television registers its account information with itself and completes the initial settings. That is, the account sharing function in the modified example realizes a function of registering for sharing account information when the display device 1 is connected to the home network 5.

As a modification, there may be a form of a home system that enables communication between a plurality of display devices 1 and between the display device 1 and an external device without going through the home network 5. In that case, the account sharing function is a function for sharing account information in the home system.

(S27) The account information sharing unit 45 of the second device uses the account information received from the first device for processing related to user authentication of the user authentication unit 44 without registering it with itself.

(S28) After that, when user authentication is performed with the content distribution server 7 for the display device 1a, which is an account server, the account information possessed by the user is used to perform processing related to user authentication. It can be carried out.

The above operation is the same regardless of which of the plurality of display devices 1 becomes the first device or the second device. In the above example, only one display device 1a is used as the account server, but the present invention is not limited to this, and two or more display devices may be used as the account server. In that case, the second device may access one of the account servers.

Further, among the plurality of display devices 1 of the home network 5, only a specific display device 1 may be set to be an account server. For example, using the user setting function of the display device 1, only the display device 1a is set so that it can be an account server. In that case, the devices other than the display device 1a are controlled so as not to become an account server based on the settings even if the mobile terminal 2 is connected for the first time.

[Processing flow]
FIG. 9 shows a processing flow at the time of initial setting in the display device 1 of the second embodiment. FIG. 9A shows a flow of the first process corresponding to the account server which is the first device. FIG. 9B shows a second processing flow corresponding to the second device. FIG. 9A has steps S141 to S145. Hereinafter, the steps will be described in order.

(S141 to S143) The steps of S141 to S143 are the same as those of S101 to S103 of the first embodiment.

(S144, S145) In S144, the account information sharing unit 45 of the first device, which is an account server, waits for a reference request for account information from the second device, which is another display device 1 of the home network 5. There is. When the account information sharing unit 45 receives the reference request, the account information sharing unit 45 proceeds to S145 at (S144-Y). In S145, the account information sharing unit 45 transmits its own account information to the second device as a response to the reference request.

FIG. 9B has steps S151 to S155. Hereinafter, the steps will be described in order.

(S151 to S153) In S151, the account information sharing unit 45 of the second device proceeds to S152 when the user authentication of the user authentication unit 44, that is, when the need for account information occurs (S151-Y). In S152, the account information sharing unit 45 confirms whether the account server, which is the first device, is connected to the home network 5. If it is connected (S152Y), proceed to S152. In S153, the account information sharing unit 45 transmits a reference request for account information to the account server, which is the first device.

(S154, S155) In S154, when the account information sharing unit 45 receives the account information transferred as a response from the account server which is the first device (S154), the process proceeds to S155. In S155, the account information sharing unit 45 uses the account information received in S154 for user authentication in the user authentication unit 44, and ends without registering in its own storage 26.

[Effects, etc.]
As described above, according to the second embodiment, the account information sharing of the home network 5 can be realized as in the first embodiment. In the second embodiment, a step of referencing from the second device to the first device is required at the time of user authentication, but there is an advantage that the account information may be securely held only by the first device. Further, when changing the setting for canceling the shared state, the shared account information may be deleted only with the first device.

(Embodiment 3)
The display device 1 and the like according to the third embodiment of the present invention will be described with reference to FIGS. 10 to 12. The basic configuration in the third embodiment is the same as that in the first embodiment. Hereinafter, components different from those of the first embodiment in the third embodiment will be described. In the third embodiment, it is assumed that a situation may occur when a plurality of account information of a plurality of mobile terminals 2 is registered in the display device 1 of the home network 5. The third embodiment has a function of deleting the account information registered in the display device 1 as a setting change depending on the situation.

[Content viewing system]
FIG. 10 shows an example of a content viewing system and an operation sequence according to the third embodiment. FIG. 10 shows that the user U2, such as a friend of the user U1, is invited to the house of the user U1 as a difference from FIG. The user U1 possesses the "smartphone A" which is his / her own mobile terminal 2a, and the user U2 possesses the "smartphone B" which is his / her own mobile terminal 2b. The user U1 has the account information 101 related to the content distribution service X1 in the mobile terminal 2a as in the first embodiment. Further, the user U2 has the account information 102 (indicated by A2) regarding the content distribution service X1 in the mobile terminal 2b. The user U2 can usually use the content distribution service X1 at the user U2's home or the like by using his / her display device, the mobile terminal 2b, and the account information 102 thereof.

In the example of FIG. 11, the user U2 who visits the house of the user U1 temporarily uses the display device 1 owned by the user U1 and uses the content distribution service X1 by using the account information 102 of the mobile terminal 2b. And watch the content. After that, the user U2 leaves the house of the user U1 and returns home. The user U2 uses the same content distribution service X1 from, for example, a display device at home. In the third embodiment, a function of controlling the shared account information of the display device 1 in the home of the user U1 in such a situation will be described.

[Operation sequence]
An example of the operation sequence of the third embodiment will be described with reference to FIG. FIG. 10 has steps S31 to S36. Hereinafter, the steps will be described in order.

(S31) First, the operation of the user U1 in the house is basically the same as the operation described in the first embodiment. That is, the account information 101 possessed by the mobile terminal 2a is registered as shared account information in, for example, the display device 1a.

(S32) The mobile terminal 2b of the user U2, who is a guest who visited the house of the user U1, is connected to, for example, the display device 1a.

(S33) The account information sharing unit 45 of the display device 1a, which is the first device, acquires the account information 102 held by the mobile terminal 2b by forwarding. The display device 1a registers the account information 102 in the account information 504 of the user authentication information 503 in its own storage 26. The account information 504 includes two items, the account information 101 of the user U1 and the account information 102 of the user U2.

In this example, as account information sharing, it is assumed that only one display device 1a holds the guest account information 102. Not limited to this, as in the first embodiment, the guest account information 102 can be held by the plurality of display devices 1 of the home network 5 by the account sharing function. In that case, the account information sharing unit 45 transfers the account information between the display devices 1 and the like, as in the first embodiment. As a result, the user U2 can view the content on each display device 1. Further, the account information 102 can be registered by connecting the guest mobile terminal 2b to any display device 1 of the home network 5. As will be described later, it is also possible to make user settings regarding whether or not guest account information can be registered in the display device 1.

(S34) The account information 102 of the user U2 is registered in the display device 1a. Therefore, the user U2 can view the content of the content distribution service X1 on the display device 1a through the user authentication using the account information 102.

(S35) After that, the user U2 finishes viewing the content, leaves the user U1's house, and returns home, for example. The state 1101 indicates that the mobile terminal 2b of the user U2 is outside the home of the user U1, for example, at the home of the user U2. The user U2 uses the content distribution service X1 from the content distribution server 7 via the external network 6 through the display device at home and the mobile terminal 2b.

In this way, when the mobile terminal 2b, which is initially in the house of the user U1 and has registered the account information 102 in the display device 1a, goes out of the house, the account information 102 of the user U2 is used in the house of the user U1 and in the house of the user U1. It exists both outside and outside the home of user U1. In such a situation, in the conventional system, a request from the user U1's home and a request from the user U1's home may occur as a request to the content distribution server. In that case, depending on the service design, if the content distribution server does not allow content viewing in different locations, for example, the result of user authentication fails for one request and viewing is disallowed. do. The third embodiment is a technique that assumes such a situation.

(S35) The account sharing unit 45 of the display device 1a, which is the first device, periodically confirms the location of the mobile terminal 2, for example, the mobile terminal 2b in which the account information is registered. As a location confirmation, the account sharing unit 45 detects and determines whether or not the registration source mobile terminal 2 is in the home associated with the home network 5 of the user U1 through the home network 5. This location confirmation is realized, for example, as follows.

The display device 1 may detect and determine whether the mobile terminal 2 is inside or outside the home by determining whether or not the mobile terminal 2 is connected to the home network 5. This connection determination may be a determination of whether or not there is a wireless connection between the display device 1 and the mobile terminal 2, or a determination of a connection between the display device 1 and the mobile terminal 2 via the home network 5. Further, the display device 1 may try wireless connection to the mobile terminal 2 based on the information when the mobile terminal 2 is first wirelessly connected, and may make a determination based on the result. That is, the display device 1 determines that the display device 1 is in the house when the wireless connection with the mobile terminal 2 is possible or there is a response, and the display device 1 is outside the house when the wireless connection is not possible or there is no response. May be determined. The display device 1 may determine that it is outside the home when the wireless connection is disconnected from the mobile terminal 2 after the first wireless connection, or when a predetermined time has elapsed after the disconnection.

The location confirmation may be realized by using short-range wireless communication between the display device 1 or the device constituting the home network 5 and the mobile terminal 2. For the location confirmation, a method of detecting the beacon or the like by the display device 1 by using the beacon or the like emitted by the mobile terminal 2 may be used. That is, the display device 1 may determine that the mobile terminal 2 is outside the house when it comes out of the predetermined radius distance range associated with the inside of the house.

In S35, it is assumed that the display device 1a detects that, among the plurality of mobile terminals 2 in the home of the user U1, the specific mobile terminal 2b in which the account information is registered is not in the home, that is, outside the home.

(S36) The account information sharing unit 45 of the display device 1a deletes the account information 102 of the mobile terminal 2b registered and held by itself based on the out-of-home detection of S35. As a result, the setting state of the display device 1a is updated, and the account information 102 is invalidated so that it cannot be used for user authentication. This prevents the user U2 from continuing to use the content viewing on the display device 1 in the home of the user U1.

[Processing flow]
FIG. 11 shows a processing flow as the first device in the display device 1 of the third embodiment. FIG. 11 has steps S161 to S165. Hereinafter, the steps will be described in order.

(S161 to S163) In S161, the first device connects to the guest mobile terminal 2, for example, the mobile terminal 2b of the user U2. In S162, the account information sharing unit 45 of the first device acquires the account information of the guest's mobile terminal 2 by transfer. In S163, the account information sharing unit 45 registers the guest account information in the account information 504 of the user authentication information 503 in its own storage 26.

(S164, S165) In S164, the account information sharing unit 45 periodically confirms the location of the guest's mobile terminal 2 which is the registration source of the account information of S163. When the account information sharing unit 45 detects and determines that the guest's mobile terminal 2 is not inside the house, that is, outside the house (S164-N), the account information sharing unit 45 proceeds to S165. In S165, the account information sharing unit 45 deletes the account information of the guest's mobile terminal 2 registered in the account information 504 of the user authentication information 503 in its own storage 26.

[Effects, etc.]
As described above, according to the third embodiment, even when a person such as a friend who has come to the user's house temporarily uses the display device 1 of the home network 5 to view the content, the setting can be easily set. It can be carried out. In that case, the guest account information registered in the display device 1 in the house is deleted when the guest's mobile terminal 2 leaves the house. As a result, there is no need to worry that the account information will continue to be used. It is also prevented that the guest user uses the display device 1 to view the content from outside the house.

[First modification]
The following is possible as a first modification of the third embodiment. In this first modification, the location confirmation of the mobile terminal 2 and the deletion of the account information are executed according to the result of the user authentication.

FIG. 12 shows a processing flow of the display device 1 as the first device in the first modification of the third embodiment. FIG. 12 has steps S171 to S176. Hereinafter, the steps will be described in order.

(S171) Similar to the third embodiment, the account information of the guest mobile terminal 2 is registered in the display device 1.

(S172, S173) In S172, user authentication with the content distribution server 7 occurs. The display device 1 transmits a content reproduction request or the like to the content distribution server 7 according to a normal content viewing operation sequence based on the operation of the guest user. At that time, the user authentication unit 44 uses the guest account information registered in itself to transmit the user authentication information including the account information to the content distribution server 7. The user authentication unit 44 receives the result of user authentication from the content distribution server 7. In S173, the display device 1 proceeds to S174 when the result of user authentication is unsuccessful (S173-Y).

(S174, S175) In S174, the account information sharing unit 45 of the display device 1 confirms the location of the guest's mobile terminal 2 which is the registration source of the account information. If the guest's mobile terminal 2 is in the house (S174-Y), there is no problem, so the process ends. If you are not at home (S174-N), proceed to S175. In S175, the account information sharing unit 45 cooperates with the user authentication unit 44 to delete the account information of the guest's mobile terminal 2 registered in itself.

When the account information is deleted, the first device has a plurality of display devices 1 held in the home network 5, and if the account information is held in the plurality of display devices 1, a plurality of display devices 1 held in the plurality of display devices 1. Delete the account information in the same way. In this case, for example, the first device transmits an instruction to delete the account information to the second device, which is another display device 1 of the home network 5. The second device that receives the instruction deletes the corresponding account information registered in itself.

In the first modification of the third embodiment, the account information is deleted when the result of the user authentication fails in the situation where the user U1 has the account information inside and outside the house as described above. As a result, the same effect as that of the third embodiment can be obtained. It should be noted that the step of confirming the location of S174 may be omitted, and the account information may be deleted immediately when the result of user authentication is unsuccessful.

(Embodiment 4)
The display device 1 and the like according to the fourth embodiment of the present invention will be described with reference to FIGS. 13 to 16. The basic configuration of the fourth embodiment is the same as that of the first embodiment. Hereinafter, components different from those of the first embodiment in the fourth embodiment will be described. In the fourth embodiment, regarding the account sharing function, the operation and setting are not the same for the plurality of display devices 1 of the home network 5, but different operations and settings are possible for each display device 1. In the fourth embodiment, the account sharing function is restricted for each display device 1. In the fourth embodiment, it is possible to set whether or not to use the account sharing function, that is, whether or not to share the account information, etc. for each individual display device 1.

The display device 1 of the fourth embodiment provides a user setting function that enables settings related to the account sharing function as user settings. This user setting function is realized by using the user setting unit 46 of FIG. The user setting unit 46 cooperates with the account information sharing unit 45. The state of the user setting is managed by using the setting information 505. The account information sharing unit 45 controls whether or not to share account information for each display device 1 based on the setting information 505 of the user setting unit 46.

In the display device 1 of the fourth embodiment, when the account information related to the account sharing function is set for the first time, the account registration screen is provided and the account registration process is performed. The first device registers account information through the account registration screen.

In the display device 1 of the fourth embodiment, the setting screen is displayed on the display device 1 by using the user setting function. The user can make settings related to the account sharing function related to the plurality of display devices 1 of the home network 5 while looking at the setting screen.

The method to be used can be selected and set from the various methods shown in the above-described first to third embodiments according to the setting using the user setting function. For example, it is possible to set that the specific display device 1 can be the first device and the specific display device 1 cannot be the first device as in the first embodiment. .. Further, the specific display device 1 can be an account server as in the second embodiment, and the other display devices cannot be an account server. Further, the specific display device 1 can be set to be a first device capable of registering guest account information, as in the third embodiment.

In the fourth embodiment, the following are also possible as settings related to the account sharing function. When one mobile terminal 2 has a plurality of account information, it is possible to set the display device 1 to select to register a part of the account information instead of registering all the account information. be. Further, when there are a plurality of mobile terminals 2 having account information, the account information of some of the mobile terminals 2 is stored in the display device 1 instead of registering the account information of all the plurality of mobile terminals 2. It is possible to set to select to register. In addition, among the content group of the content distribution service related to the account information, it is possible to set to allow viewing of specific content and disable viewing of specific content.

Account information sharing can be set for each account information and each mobile terminal 2. For example, it is assumed that the first mobile terminal has the first and second account information. In the user setting, the first account information can be shared by all the display devices of the home network 5, and the second account information can be held only by the specific display device 1.

The user setting unit 46 displays the setting screen on the display unit 20, and the user can set the user by inputting the display device 1 through the input means 23 while looking at the setting screen. Further, as described above, the user may operate the display device 1 from the mobile terminal 2, which enables user setting in the same manner. In that case, the user setting unit 46 may display the setting screen on the screen of the mobile terminal 2.

The timing of user setting using the user setting function can be as follows. The user can call and use the setting screen by the user setting function by operating the display device 1 or the mobile terminal 2 at basically arbitrary timing. For example, the user can be set in advance before the initial setting. In addition, user settings can be made even after the initial settings. At the time of initial setting, the account registration screen is displayed, but it is possible to transition to the setting screen at that time as well.

[Content viewing system]
FIG. 13 shows an example of the content viewing system and the operation sequence according to the third embodiment. FIG. 13 differs from FIG. 1 in that the mobile terminal 2A of the user U1 has the account information 111 (indicated by A001), and the other mobile terminal 2B has the other account information 112 (indicated by A002). The account information 111 is for the content distribution service X1 of the content distribution server 7a, and the account information 112 is for the content distribution service X2 of the content distribution server 7b.

The display device 1a displays the account registration screen at the time of initial setting by the user setting unit 46, and also displays the setting screen at an arbitrary timing.

[Operation sequence]
An example of the operation sequence at the time of initial setting in the fourth embodiment will be described with reference to FIG. In this example, the account information 111 possessed by the mobile terminal 2A is registered in the display device 1a and shared by all the display devices 1 in the home network 5. The account information 112 held in the mobile terminal 2B is registered only in the specific display device 1 based on the user settings. FIG. 13 has steps S41 to S48. Hereinafter, the steps will be described in order.

(S41) First, the registration of the account information 111 will be described. For example, the mobile terminal 2A is connected to the display device 1a.

(S42) The user setting unit 46 of the display device 1a, which is the first device, displays the account registration screen (FIG. 14 described later) on the screen of the display unit 20 of the display device 1a at the time of initial setting. The user looks at the account registration screen and confirms whether or not to register the account information 111 held in the mobile terminal 2A as the shared account information of all the display devices 1 including the display device 1a. When registering, the user inputs to the effect of registration.

(S43) The user setting unit 46 performs an account registration process based on the user confirmation input through the account registration screen of S42, and registers the account information 111 in the display device 1a. Specifically, this process includes S44 to S46.

(S44 to S46) In S44, the account information sharing unit 45 acquires the account information 111 from the mobile terminal 2 by forwarding. In S45, the account information sharing unit 45 registers the account information 111 in the account information 504 of the user authentication information 503 in the storage 26 as shared account information. In S46, the account information sharing unit 45 performs transfer or the like in the same manner as in the first embodiment so that the account information 111 is shared among the plurality of display devices 1 of the home network 5. For example, the account information sharing unit 45 of the display device 1n registers the account information 111 transferred from the display device 1a to itself.

(S47) After that, for example, the user can connect the mobile terminal 2A to the display device 1n and use the content distribution service X1 from the display device 1n. At this time, since the account information 111 has already been registered in the display device 1n as the shared account information, the display device 1n does not output the account registration screen. The display device 1n requests the content distribution server 7a, for example, the content C1 based on the user operation. At the time of user authentication, the display device 1n creates user authentication information using the account information 111 held by the display device 1n and transmits the user authentication information to the content distribution server 7a. As a result, the user can view the content C1 from the content distribution server 7a on the display device 1n without the trouble of registering the account information.

(S48) The registration of the account information 112 held in the mobile terminal 2B is as follows. The user U1 calls the user setting function by an input operation to any display device 1, for example, the display device 1a. At this time, the user U1 may connect the mobile terminal 2B to the display device 1a to perform an input operation. The user setting unit 46 displays a setting screen (FIG. 15 described later) on the display device 1a. The setting screen has setting items such as whether or not to share account information for each display device 1 for a plurality of display devices 1 of the home network 5. When the user U1 wants to register the account information 112 only in the display device 1a, for example, the user U1 selects and sets the account information 112 to be registered only in the display device 1a on the setting screen. The user setting unit 46 saves the setting state in the setting information 505. When the user U1 subsequently completes the registration of the account information 112, the user U1 connects the mobile terminal 2B to, for example, the display device 1a. The account information sharing unit 45 of the display device 1a registers the account information 112 in its own storage 26 based on the setting information 505, and prevents the account information 112 from being registered in the other display device 1.

[Account registration screen]
FIG. 14 shows an example of an account registration screen output by the display device 1 to which the mobile terminal 1 is connected at the time of initial setting. This account registration screen includes item f1, item f2, and item f3.

In item f1, a registration confirmation message or the like is displayed. In this example, in item f1, "Do you want to register the account information on the mobile terminal as shared account information on all TVs including" TV1 "? Is displayed. Further, in item f1, the content of the account information is displayed for confirmation. In addition, in item f1, a yes / no button corresponding to whether or not to register is displayed. The user can select whether or not to register in the item f1. When registration (yes) is selected, it corresponds to the setting that the account sharing function is used on all the display devices 1 of the home network 5. Then, the operation sequence shown in the first embodiment or the like is automatically executed.

Further, when not registered (No) is selected in the item f1, the item f2 may be displayed. Item f2 is an item corresponding to the case where the account information is registered only in one display device 1 as in the conventional case. In this example, in item f2, "Do you want to register the account information on the mobile terminal as account information only on" TV1 "? Is displayed. When registration (yes) is selected, the account sharing function is not applied, and the account information is not registered in the other display device 1 of the home network 5.

Further, in item f3, a button that enables user setting related to the account sharing function is displayed. When this item f3 is selected, the screen transitions to the setting screen as shown in FIG.

The user setting unit 46 displays a table having contents corresponding to the current setting state based on the setting information 505. In this table, the items include the name of the display device 1 which is a device, the device ID, account sharing availability, and content availability. In the "account sharing possibility" item, it is possible to set whether or not to apply the account sharing function for each display device 1 indicated by the device ID. The user can set whether or not to allow each display device 1 by operating a check button, for example, in the "account sharing availability" item. The display device 1 set to be acceptable in this item operates by the account sharing function. The display device 1 set to be disabled in this item does not operate by the account sharing function. For example, the display device 1n indicated by "TVn" in the fourth line is set to be disabled, does not become the first device and the second device described above, and does not have account information.

Item g4 is a display example at the time of initial setting before registering account information, and items of individual account information and information related to the mobile terminal 2 are not displayed. Items that enable individual settings for each account information and individual settings for each mobile terminal 2 can also be realized in the same manner.

Further, the "content availability" item is a setting item relating to viewing availability for each content on the display device 1 indicated by the device ID. Regarding the setting of the content of the "content availability" item, it is possible in the item g5. Item g5 is a setting item for whether or not to allow each content. In item g5, the ID of the content distribution service associated with the account information can also be selected. In item g5, a content list is displayed for each account information and content distribution service. The display device 1 acquires the content list information based on the communication with the content distribution server 7. In this example, the item g5 displays a list of contents corresponding to a certain account information in a table. Not limited to this, a format in which icons for each content are arranged may be used. Each content in the list has items such as explanatory information (not shown) and viewing availability. The user can set whether or not to allow each content in the "viewability" item, for example, by operating a check button. In addition, basically all the contents may be shared and non-shared contents may be selected, or basically all contents may be non-shared and shared contents may be selected.
