As the content distribution service, there are an IPTV service and the like. The IPTV service is a service to distribute contents, such as a movie film and a video distribution program, which contain a video, an audio, character information and the like, to an apparatus of a user on the Internet. The apparatus of the user is a content reproducing apparatus, and is a display apparatus such as a mobile terminal and a TV receiver.
The apparatus has account information for allowing the user to view contents by using the content distribution service. The user is registered as a regular user to a content distribution server of a service provider by registering the account information and the like. The content distribution server carries out authentication by using the account information in order to control authority of services and contents. The user and the apparatus are required to obtain certification by using the account information when to use a service and view contents. The control of authority using the authentication allows violation of laws, such as unapproved copy, movement, change and the like regarding the contents, to be prevented.
The authentication may be requested at the time of log-in to the content distribution service, or may be requested when to reproduce each of contents.
For example, the content distribution server carries out user authentication. The content distribution server compares and checks the registered account information with account information received from the apparatus of the user, thereby carrying out the user authentication. As the authentication, apparatus authentication may be carried out in addition to the user authentication. The apparatus authentication is authentication regarding the apparatus that the user uses to view contents. In the apparatus authentication, it is confirmed whether the apparatus is a permitted apparatus or recommended apparatus or not.
The account information is information that is associated with an account set to the user for each content distribution service. The account information is information on a combination of a user ID and a password, for example. However, it is not limited to this. As the user authentication, biometrics authentication may be included. In that case, information for the biometrics authentication may be contained in the account information.
Means for predetermined protection, for example, encryption or the like may be applied to the account information and contents to be distributed. For example, contents are encrypted in advance in a predetermined method, and key information for decoding is exchanged separately. The key information is managed together with a content reproducing condition.
In the content distribution service, a usage fee is often charged by the service provider. The charging is carried out in a predetermined method, and charging information is recorded. For example, the usage fee is calculated on the basis of counts when to accumulate data and view contents in the apparatus of the user.
The same user basically reproduces contents of the content distribution service by the same apparatus, but there is a service in which a plurality of users and a plurality of apparatuses are permitted to reproduce contents under a predetermined condition. As a content distribution method, there are streaming, download, progressive download, and the like. Contents may accompany a program such as application software. The program operates when to reproduce the contents by the apparatus of the user.

The display apparatus 1 displays the portal screen on the basis of communication with the content distribution server 7. The portal screen contains content list information and the like. The user is allowed to select or search target contents to be viewed on the portal screen. The user can view contents in a log-in state without requiring user authentication. The display apparatus 1 transmits a content reproducing request including a content ID of contents selected by the user to the content distribution server 7. When the content reproducing request is received, the content distribution server 7 distributes the specified contents.
In a case where user authentication for each content is carried out, it is as follows. The display apparatus 1 of the user transmits the content reproducing request, which contains the content ID of the contents selected by the user via the portal screen or the like, to the content distribution server 7. The content distribution server 7 transmits the user authentication information request to the display apparatus 1 for user authentication for each of the contents. When the user authentication information request is received, the display apparatus 1 transmits the user authentication information containing the account information to the content distribution server 7. The content distribution server 7 carries out the user authentication similarly. In a case where a result of the user authentication is success, the content distribution server 7 transmits a response that reproduction of the contents is permitted, and distributes the specified contents. In a case where the result is failure, the content distribution server 7 transmits a response that reproduction of the contents is not permitted. The content reproducing request and the user authentication information may be transmitted together.
[Initial Setting]
An operation and processing at the time of initial setting regarding the account information according to the first embodiment will be described with reference to
[Operating Sequence]
(S1) The mobile terminal 2 of the user U1 is connected to any display apparatus 1 of the home network 5, for example, the display apparatus 1a by wireless connection or the like. The display apparatus 1a to which the mobile terminal 2 is connected in this manner is also referred to as “first apparatus” for convenience of explanation.
(S2) The account information sharing unit 45 of the display apparatus 1a that is the first apparatus communicates with the mobile terminal 2 to obtain the account information 101 that the mobile terminal 2 has therein by causing the display apparatus 1a to transfer it. At the time of this transfer, it may be transferred in response to a request from the first apparatus to the mobile terminal 2, or transferred in response to an instruction from the mobile terminal 2 to the first apparatus. Further, the user may carry out an input operation corresponding to the initial setting against the mobile terminal 2 or the display apparatus 1. The mobile terminal 2 or the display apparatus 1 may receive the input operation to carry out transfer of the account information.
(S3) The account information sharing unit 45 of the display apparatus 1a, which is the first apparatus registers, as the shared account information, the account information 101 obtained from the mobile terminal 2 to the account information 504 of the user authentication information 503 in the storage 26 of the display apparatus 1a.
(S4) On the other hand, other display apparatus 1 of the home network 5, for example, the display apparatus 1b does not hold account information therein at the time of the initial setting. The other display apparatus 1 such as the display apparatuss 1b to 1n is also referred to as “second apparatus” for convenience of explanation. The account information sharing unit 45 of the display apparatus 1b that is the second apparatus make an inquiry regarding the account information to the other display apparatus 1 of the home network 5, for example, the display apparatus 1a. This inquiry is an inquiry of whether to hold the account information or not, and is an inquiry containing a transfer request in a case where the account information is held.
(S5) The display apparatus 1a that is the first apparatus carries out a response when to receive the inquiry from the display apparatus 1b that is the second apparatus. The account information sharing unit 45 of the first apparatus reads out the account information, which has already been registered in its own storage as the shared account information, to transfer information containing the account information to the display apparatus 1b as an inquiry source, which is the second apparatus.
(S6) When the information containing the account information transferred from the display apparatus 1a as an inquiry destination is received as a response, the display apparatus 1b as the inquiry source registers the account information in the account information 504 of the user authentication information 503 in its own storage 26 as the shared account information. This causes a state where the account information is also held in the display apparatus 1b. The display apparatus 1n and the like that are the other display apparatuss 1 carry out the above operation similarly, thereby becoming a state the same account information is held in each of the display apparatuss 1. This causes a state where the initial setting has been finished. The above operation is similar even in a case where any of the plurality of display apparatuss 1 become the first apparatus and the second apparatus. For example, in a case where the mobile terminal 2 is first connected to the display apparatus 1b, the display apparatus 1b becomes the first apparatus and the other display apparatus 1 becomes the second apparatus.
(S7) Then, when user authentication with the content distribution server 7 is carried out, the display apparatus 1a that is the first apparatus can carry out a process related to the user authentication by using the account information, which has already been registered therein at S3, by means of the user authenticating unit 44.
(S8) Further, the mobile terminal 2 of the user U1 is then connected to the display apparatus 1b that is the second apparatus. In this case, the account information has already been registered in the display apparatus 1b at S6. For this reason, there is no need to transfer the account information from the mobile terminal 2 to the display apparatus 1b, and there is also no need to carry out an account registering process.
(S9) As well as the display apparatus 1a, when the user authentication with the content distribution server 7 is carried out, the display apparatus 1b that is the second apparatus can carry out the process related to the user authentication by using the account information, which has already been registered therein at S6, by means of the user authenticating unit 44.
[Processing Flow (1)]
(S101) The first apparatus is connected to the mobile terminal 2.
(S102) The account information sharing unit 45 requests the mobile terminal 2 to transfer account information that the mobile terminal 2 has. This causes the account information to be transferred from the mobile terminal 2 to the display apparatus 1. The account information sharing unit 45 receives and obtains the transferred account information.
(S103) The account information sharing unit 45 registers the account information obtained at S102 in the account information 504 of the user authentication information 503 in the storage 26 as the shared account information. At this time, the account information may be transferred or delivered from the account information sharing unit 45 to the user authenticating unit 44 to register the account information by the user authenticating unit 44.
(S104) The account information sharing unit 45 waits for inquiry from the second apparatus that is another display apparatus 1 of the home network 5. Ina case where the second apparatus receives inquiry from the account information sharing unit 45 (S104—Y), the processing flow proceeds to S105.
(S105) The account information sharing unit 45 determines whether there is a problem or not even when the account information is provided to the second apparatus in response to the inquiry from the second apparatus. After it is confirmed that there is no problem, the account information sharing unit 45 reads out the shared account information held in the account information 504 of the storage 26, and transfers information containing the account information to the second apparatus that carried out the inquiry via the home network 5.
There are Steps S111 to S115 in (B) of
(S111) The account information sharing unit 45 of the second apparatus confirms whether the account information is held in the account information 504 of its own storage 26 or not, that is, whether the shared account information has already been registered or not. In a case where it is held (S111—Y), the processing flow terminates the process for the initial setting. In a case where it is not held (S111—N), the processing flow proceeds to S112.
(S112) The account information sharing unit 45 confirms whether the other display apparatus 1 is connected to the home network 5 or not. In this regard, this step may be omitted in a case where it is known in advance connection and the display apparatus 1 thereof. In a case where the other display apparatus 1 is connected (S112—Y), the processing flow proceeds to S113. In a case where no display apparatus 1 is connected (S112—N), the processing flow is terminated.
(S113) The account information sharing unit 45 transmits information on the inquiry regarding the account information to the other display apparatus 1 in the home network 5 via the home network 5. The other display apparatus 1 as an inquiry destination may be the first apparatus, or may be the second apparatus.
(S114) In a case where the account information is transferred to the account information sharing unit 45 as a response from the first apparatus (S114—Y), the processing flow proceeds to S115. In a case where it is not transferred, the other display apparatus 1 as the inquiry destination is the second apparatus in which the account information is not held. The account information sharing unit 45 similarly carries out an inquiry in a case where there is the other display apparatus 1. In a case where the account information is not transferred from any of the display apparatuss 1 (S114—N), the processing flow is terminated.
(S115) The account information sharing unit 45 registers the account information received from the first apparatus to the account information 504 of the user authentication information 503 in its own storage 26 as the shared account information. Herewith, the process for the initial setting is terminated.
In this regard, as a modification example, the confirmation of whether the account information is held or not and a request of transfer in the inquiry at S113 may be separated as separate communicating steps. Further, the second apparatus may similarly make an inquiry to all of the other display apparatuss 1 of the home network 5 at the time of the inquiry, or may make an inquiry to a specific display apparatus 1. For example, in a case where the first apparatus in the home network 5 is known in advance, the account information sharing unit 45 may transmit a request of transfer to only the first apparatus. Further, when to transfer the account information among the display apparatuss 1, the account information may be subjected to encryption or the like.
The account information sharing unit 45 may manage, as information, a state of holding and sharing of the account information in the plurality of display apparatuss 1 of the home network 5 in a table. For example, information on an apparatus ID, whether the account information of each of the display apparatuss 1 is held or not, a role thereof and the like may be managed in the table for each piece of account information. As the role, there are the first apparatus, the second apparatus and the like.
As described above, according to the content viewing system of the first embodiment, it is possible to reduce labor for the user to set the account information to the plurality of display apparatuss 1 of the home network 5 while securing control of authority to view contents by using the account information as a premise, and this makes it possible to user-friendly improve convenience in various environments and situations.
For example, the user may carry out a work to register the account information that the mobile terminal 2 has to the first apparatus that is one of the display apparatuss 1 of the home network 5 during the initial setting. This causes a state where the account information is automatically registered to the plurality of display apparatuss 1 of the home network 5 to become sharing available. There is no need to separately register the account information to each of the display apparatuss 1 of the home network, and this makes labor of the user smaller.
The prior art is not a technique in which it is not considered that a mobile terminal and a display apparatus work together. Even in a case where the mobile terminal has account information, it is not easy to share the account information with a plurality of display apparatuss of a home network. On the other hand, according to the first embodiment, such sharing can be easily realized by a simple operation.
The following is cited as a modification example of the first embodiment. First, for example, there is a first television and a second television as the plurality of display apparatuss 1 of the home network 5. Account information of the mobile terminal 2 has already been registered to the first television. A third television is newly added to home. An account information sharing unit 45 of the third television makes an inquiry to the other display apparatus 1 of the home network 5, for example, the first television for its own initial setting when the third television is connected to the home network 5. The first television that receives the inquiry transfers the account information to the third television. The third television registers the account information thereto, and terminates the initial setting. Namely, an account sharing function according to the modification example realizes a function to carry out registration for sharing the account information when the display apparatus 1 is connected to the home network 5.
As another modification example, it may be a form of a home system that allows communication between a plurality of display apparatuss 1 and between each of the display apparatuss 1 and an external apparatus without a home network 5. In that case, an account sharing function is a function to share account information in the home system.
The following is possible as a first modification example of the first embodiment. A first apparatus that is a display apparatus 1 registers therein account information obtained from a mobile terminal 2, and immediately transfers it to second apparatuses that are the other display apparatuss 1 in a home network 5. The second apparatus that receives the account information thus immediately transferred registers the account information thereto.
(S11 to S13) At S11, the mobile terminal 2 of the user U1 is connected to any display apparatus 1 of the home network 5, for example, the display apparatus 1a. At S12, the account information sharing unit 45 of the display apparatus 1a that is the first apparatus causes the mobile terminal 2 to transfer the account information 101 that the mobile terminal 2 has to the display apparatus 1a to obtain it. At S13, the account information sharing unit 45 registers the account information 101 obtained from the mobile terminal 2 to the user authentication information 503 therein as the shared account information.
(S14) Moreover, the account information sharing unit 45 of the display apparatus 1a that is the first apparatus immediately transfers information containing the account information at S13 to each of the second apparatuses that are the other display apparatuss of the home network 5. This information thus immediately transferred is also a registering instruction to the second apparatus. This immediate transfer may be carried out by broadcast transmission to the other display apparatuss 1 of the home network 5, for example, or may be carried out by sequential transmission to each of the other display apparatuss 1 in a predetermined order.
(S15) On the other hand, each of the second apparatuses that are the other display apparatuss 1 of the home network 5, for example, the display apparatus 1b receives the information immediately transferred at S14 from the first apparatus. The second apparatus registers the account information to the user authentication information 503 therein as the shared account information. This causes a state where the account information is also held in the display apparatus 1b. Similarly, it becomes a state where the account information is held in each of the display apparatuss 1. This causes a state where the initial setting has already been finished. The above operation is similar even in a case where any of the plurality of display apparatuss 1 become the first apparatus and the second apparatus.
(S16) Then, the display apparatus 1a or the display apparatus 1b can carry out the process related to the user authentication by using the account information that has already been registered thereto when the user authentication with the content distribution server 7 is carried out.
According to the first modification example of the first embodiment, the inquiry described above is not required, and by carrying out immediate transfer, it is possible to shorten a time required for the initial setting.
A display apparatus 1 and the like according to a second embodiment of the present invention will be described with reference to
In the second embodiment, a first apparatus that is a display apparatus 1 to which account information of a mobile terminal 2 is registered among a plurality of display apparatuss 1 of the home network 5 is set to an “account server”. The “account server” mentioned herein means an apparatus and a role that representatively manages account information in the home network 5. The account information is not registered to a second apparatus that is another display apparatus 1 in the home network 5. Whenever the account information is required for user authentication, the second apparatus accesses the account server that is the first apparatus, and refers to and uses the account information.
[Operating Sequence]
(S21) A mobile terminal 2 of a user U1 is connected to any display apparatus 1 of the home network 5, for example, a display apparatus 1a.
(S22) Account information sharing unit 45 of the display apparatus 1a that is the first apparatus causes the display apparatus 1a to transfer account information 101 that the mobile terminal 2 has thereto, and obtains it.
(S23) The account information sharing unit 45 registers, as shared account information, the account information 101 obtained from the mobile terminal 2 in account information 504 of user authentication information 503 of its own storage 26. The display apparatus 1a that is the first apparatus becomes the account server that manages the shared account information. The initial setting is basically terminated up to this point.
In this regard, after S23, a step of notifying, from the display apparatus 1a that is the first apparatus, each of second apparatuses that are the other display apparatuss 1 that the display apparatus 1a becomes an account server may further be provided.
(S24) On the other hand, the second apparatus that is the other display apparatus 1 of the home network 5 does not hold the account information. User authentication with a content distribution server 7 occurs in the second apparatus, for example, the display apparatus 1b. Namely, necessity of account information occurs for the user authentication.
(S25) An account information sharing unit 45 of the second apparatus transmits a reference request of the account information to the account server that is the first apparatus of the home network 5.
(S26) In a case where a reference request is received from the second apparatus, the account information sharing unit 45 of the first apparatus transmits, as a response, the account information, which has already been registered thereto at S23, to the second apparatus as a requestor.
(S27) The account information sharing unit 45 of the second apparatus does not register the account information received from the first apparatus to the second apparatus, but uses it in a process related to the user authentication of the user authenticating unit 44.
(S28) Further, then, when user authentication with the content distribution server 7 is carried out, the display apparatus 1a that is the account server can use the account information held therein to carry out a process related to the user authentication.
The above operation is similar even in a case where any of the plurality of display apparatuss 1 become the first apparatus and the second apparatus. Only one display apparatus 1a is set as the account server in the above example. However, it is not limited to this. Two or more display apparatuss 1 may become the account server. In that case, the second apparatus may access any of the account servers.
Moreover, only a specific display apparatus 1 of the plurality of display apparatuss 1 of the home network 5 may be set so as to become the account server. For example, by using a user setting function of the display apparatus 1, only the display apparatus 1a is set so as to become the account server. In that case, even though the mobile terminal 2 is first connected to any of apparatuses other than the display apparatus 1a, it is controlled so as not to become an account server on the basis of setting.
[Processing Flow]
(S141 to S143) Steps S141 to S143 are similar to Steps S101 to S103 in the first embodiment.
(S144, S145) At S144, the account information sharing unit 45 of the first apparatus that is the account server waits for a reference request of the account information from the second apparatus that is another display apparatus 1 of the home network 5. In a case where the account information sharing unit 45 receives a reference request (S144—Y), the processing flow proceeds to S145. At S145, the account information sharing unit 45 transmits, as a response to the reference request, the account information that the first apparatus has to the second apparatus.
There are Steps S151 to S155 in (B) of
(S151 to S153) At S151, in a case where user authentication by the user authenticating unit 44, that is, necessity of the account information occurs (S151—Y), the account information sharing unit 45 of the second apparatus causes the processing flow to proceed to S152. At S152, the account information sharing unit 45 confirms whether the account server that is the first apparatus is connected to the home network 5 or not. In a case where they are connected to each other (S152—Y), the processing flow proceeds to S152. At S153, the account information sharing unit 45 transmits a reference request of the account information to the account server that is the first apparatus.
(S154, S155) At S154, in a case where the account information sharing unit 45 receives the account information, which is transferred as the response, from the account server that is the first apparatus (S154), the processing flow proceeds to S155. At S155, the account information sharing unit 45 causes the user authenticating unit 44 to use the account information received at S154 for the user authentication, and terminates the processing flow without registering it in its own storage 26.
As described above, according to the second embodiment, it is possible to realize sharing of the account information of the home network 5 as well as the first embodiment. In the second embodiment, a step of referring to the first apparatus from the second apparatus becomes necessary at the time of the user authentication. However, there is an advantage that the account information may be held securely only in the first apparatus. Further, in a case where setting for releasing a sharing state is to be changed, deletion of the shared account information and the like may be carried out only in the first apparatus.
A display apparatus 1 and the like according to a third embodiment of the present invention will be described with reference to
[Content Viewing System]
In the example of
[Operating Sequence]
An example of an operating sequence according to the third embodiment will be described with reference to
(S31) First, an operation in home of the user U1 is basically similar to the operation that has been explained in the first embodiment. Namely, the account information 101 that the mobile terminal 2a has is registered to the display apparatus 1a as the shared account information, for example.
(S32) The mobile terminal 2b of the user U2 who is a guest visiting home of the user U1 is connected to the display apparatus 1a, for example.
(S33) Account information sharing unit 45 of the display apparatus 1a that is the first apparatus obtains the account information 102 that the mobile terminal 2b has by means of transfer. The display apparatus 1a registers the account information 102 to the account information 504 of the user authentication information 503 in its own storage 26. The account information 504 becomes a state where two of the account information 101 of the user U1 and the account information 102 of the user U2 are contained.
In the present embodiment, as sharing of the account information, the account information 102 of the guest is held in only one display apparatus 1a. It is not limited to this. As well as the first embodiment and the like, the account information 102 of the guest can be held in the plurality of display apparatuss 1 of the home network 5 by means of the account sharing function. In that case, the account information sharing unit 45 carries out transfer of the account information among the display apparatuss 1 and the like as well as the first embodiment. This makes it possible for the user U2 to view contents via each of the display apparatuss 1. Further, the mobile terminal 2b of the guest can be connected to any of the display apparatuss 1 of the home network 5 to register the account information 102. Although it will be described later, user setting about whether the account information of the guest can be registered to the display apparatus 1 or not is possible.
(S34) It becomes a state where the account information 102 of the user U2 is registered to the display apparatus 1a. Therefore, the user U2 can view contents of the content distribution service X1 on the display apparatus 1a through the user authentication using the account information 102.
(S35) Then, the user U2 terminates to view the contents, and goes out from the home of the user U1 to his or her home, for example. A state 1101 shows a state where the mobile terminal 2b of the user U2 exists outside the home of the user U1, for example, in 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 apparatus in the home and the mobile terminal 2b.
Thus, in a case where the mobile terminal 2b whose account information 102 is registered to the display apparatus 1a becomes a situation to first exist in the home of the user U1 and go to the outside of the home, the account information 102 of the user U2 exists at both the home of the user U1 and the outside of the home of the user U1. In the case of such a situation, in the conventional system, a request from the home of the user U1 and a request from the outside of the home of the user U1 may occur as requests for a content distribution server. In that case, in a case where the content distribution server does not permit to view contents at a different place depending upon a service design, for example, a result of the user authentication for one request is set to failure not to permit viewing. The third embodiment is a technique in which such a situation is supposed.
(S35) The account information sharing unit 45 of the display apparatus 1a that is the first apparatus, for example, regularly carries out whereabouts confirmation for the mobile terminal 2 to which the account information is registered, for example, the mobile terminal 2b. The account information sharing unit 45 carries out, as the whereabouts confirmation, detection and determination of whether the mobile terminal 2 of a registration source is in home associated with the home network 5 of the user U1 or not through the home network 5. This whereabouts confirmation is realized as follows, for example.
The display apparatus 1 may detect and determine whether the mobile terminal 2 is in or outside home by determining whether the mobile terminal 2 is connected to the home network 5 or not. This connection determination may be determined on the basis of presence or absence of wireless connection between the display apparatus 1 and the mobile terminal 2, or may be determined on the basis of presence or absence of connection between the display apparatus 1 and the mobile terminal 2 via the home network 5. Further, the display apparatus 1 may try wireless connection to the mobile terminal 2 on the basis of information when to first carry out wireless connection to the mobile terminal 2, and determine it on the basis of its result. Namely, in a case where the wireless connection to the mobile terminal 2 is possible or there is a response therefrom, the display apparatus 1 may determine that the mobile terminal 2 exists in the home. In a case where the wireless connection is impossible or there is no response therefrom, the display apparatus 1 may determine that the mobile terminal 2 exists outside the home. In a case where wireless connection to the mobile terminal 2 is first established and the wireless connection is then cut or a predetermined time elapses after cutting the wireless connection, the display apparatus 1 may determine that the mobile terminal 2 exists outside the home.
The whereabouts confirmation may be realized by using short-range wireless communication between an apparatus constituting the display apparatus 1 or the home network 5 and the mobile terminal 2. The whereabouts confirmation may use a method to use a beacon emitted by the mobile terminal 2 or the like and detect the beacon or the like by the display apparatus 1. Namely, the display apparatus 1 may determine that the mobile terminal 2 exists outside the home in a case where the mobile terminal 2 goes out from within a predetermined radius distance range associated with the home.
At S35, the display apparatus 1a detects that a specific mobile terminal 2b whose account information is registered of a plurality of mobile terminals 2 that exists in the home of the user U1 does not exist in the home, that is, exists outside the home.
(S36) The account information sharing unit 45 of the display apparatus 1a deletes the account information 102 of the mobile terminal 2b, which is registered and held thereto on the basis of detection of outside home at S35. Herewith, a setting state of the display apparatus 1a is updated to be invalidated so that the account information 102 cannot be used for the user authentication. This causes the user U2 to be set so that the user U2 cannot continue to use viewing of contents via the display apparatus 1 in the home of the user U1.
[Processing Flow]
(S161 to S163) At S161, the first apparatus is connected to the mobile terminal 2 of a guest, for example, the mobile terminal 2b of the user U2. At S162, the account information sharing unit 45 of the first apparatus obtains account information of the mobile terminal 2 of the guest by means of transfer. At S163, the account information sharing unit 45 registers the account information of the guest to the account information 504 of the user authentication information 503 in its own storage 26.
(S164, S165) At S164, the account information sharing unit 45 regularly carries out whereabouts confirmation of the mobile terminal 2 of the guest, which is a registration source of the account information at S163. In a case where the account information sharing unit 45 detects and determines that the mobile terminal 2 of the guest does not exist in the home, that is, exists outside the home (S164—N), the processing flow proceeds to S165. At S165, the account information sharing unit 45 deletes the account information of the mobile terminal 2 of the guest, which is registered to the account information 504 of the user authentication information 503 in its own storage 26.
As described above, according to the third embodiment, even in a case where a person such as a friend who comes to the home of the user temporarily uses the display apparatus 1 of the home network 5 to view contents, it is possible to carry out its setting easily. Further, in that case, the account information of the guest, which is registered to the display apparatus 1 in the home is deleted in a case where the mobile terminal 2 of the guest goes out from the home. Herewith, there is no worry that the account information is kept being used. The user as the guest is prevented from using the display apparatus 1 from the outside to view contents and the like.
The following is possible as a first modification example of the third embodiment. In this first modification example, whereabouts confirmation and account information deletion for a mobile terminal 2 are carried out in accordance with a result of user authentication.
(S171) As well as the third embodiment, account information of the mobile terminal 2 of a guest is registered in the display apparatus 1.
(S172, S173) At S172, user authentication with a content distribution server 7 occurs. The display apparatus 1 transmits a content reproducing request and the like to the content distribution server 7 on the basis of an operation of the user as the guest in accordance with a normal content view operating sequence. At that time, the user authenticating unit 44 transmits user authentication information containing the account information to the content distribution server 7 by using the account information of the guest that has already been registered thereto. The user authenticating unit 44 receives a result of user authentication from the content distribution server 7. At S173, in a case where in the display apparatus 1 the result of the user authentication is failure (S173—Y), the processing flow proceeds to S174.
(S174, S175) At S174, the account information sharing unit 45 of the display apparatus 1 carries out the whereabouts confirmation of the mobile terminal 2 of the guest, which is a registration source of the account information. In a case where the mobile terminal 2 of the guest is in home (S174—Y), the processing flow is terminated because there is no problem. In a case where it is not in home (S174—N), the processing flow proceeds to S175. At S175, the account information sharing unit 45 works together with the user authenticating unit 44 to delete the account information of the mobile terminal 2 of the guest, which is registered thereto.
In this regard, in a case where the account information is held in a plurality of display apparatuss 1 of a home network 5 when to delete the account information, the first apparatus similarly deletes plural pieces of account information held in the plurality of display apparatuss 1. In this case, for example, the first apparatus transmits an instruction to delete the account information to a second apparatus that is another display apparatus 1 of the home network 5.
